Gemini in Google Drive may finally be useful now that it can analyze videos

AI, Artificial Intelligence, Gemini, Google, Tech / Kris Guyer / May 30, 2025

Google’s rapid adoption of AI has seen the Gemini “sparkle” icon become an omnipresent element in almost every Google product. It’s there to summarize your email, add items to your calendar, and more—if you trust it to do those things. Gemini is also integrated with Google Drive, where it’s gaining a new feature that could make it genuinely useful: Google’s AI bot will soon be able to watch videos stored in your Drive so you don’t have to.

Gemini is already accessible in Drive, with the ability to summarize documents or folders, gather and analyze data, and expand on the topics covered in your documents. Google says the next step is plugging videos into Gemini, saving you from wasting time scrubbing through a file just to find something of interest.

Using a chatbot to analyze and manipulate text doesn’t always make sense—after all, it’s not hard to skim an email or short document. It can take longer to interact with a chatbot, which might not add any useful insights. Video is different because watching is a linear process in which you are presented with information at the pace the video creator sets. You can change playback speed or rewind to catch something you missed, but that’s more arduous than reading something at your own pace. So Gemini’s video support in Drive could save you real time.

Suppose you have a recorded meeting in video form uploaded to Drive. You could go back and rewatch it to take notes or refresh your understanding of a particular exchange. Or, Google suggests, you can ask Gemini to summarize the video and tell you what’s important. This could be a great alternative, as grounding AI output with a specific data set or file tends to make it more accurate. Naturally, you should still maintain healthy skepticism of what the AI tells you about the content of your video.

Trump admin tells SCOTUS: ISPs shouldn’t be forced to boot alleged pirates

Cox, Policy, Sony / Kris Guyer / May 29, 2025

Enhanced damages can be $150,000 per work, instead of the usual cap of $30,000. The jury in the case “was instructed that it could find Cox’s violations willful if Cox knew that its subscribers had committed infringement,” Sauer wrote. “That instruction was mistaken because it allowed the jury to award enhanced damages even if Cox reasonably believed that its own conduct in declining to terminate infringing subscribers’ Internet access was consistent with the Copyright Act.”

Reject Sony petition, US says

Sony wasn’t happy with the 4th Circuit ruling, either, because it threw out the $1 billion award and a finding of vicarious infringement. Sony argued that Cox profited from infringement by failing to terminate infringing subscribers and that the ruling “eliminates an especially important tool in the digital age where pursuing direct infringers—in this case, thousands of faceless individuals who cannot be identified except through an Internet service provider like Respondent—is impractical at best and impossible at worst.”

Sauer urged the Supreme Court to reject Sony’s petition for a review. “The court of appeals correctly held that Sony had not satisfied its burden of showing that Cox financially benefited from infringement on its network. As the court explained, Cox charges its customers a flat fee for Internet service, regardless of what its users do online,” Sauer wrote.

Sauer compared Cox to a landlord who charges a fixed rent regardless of what tenants use the leased premises for. “There was no evidence that Cox would be forced to collect a lower fee if the users of its Internet service ceased to infringe; that subscribers were drawn to Cox’s Internet service because of the ability to engage in copyright infringement using that service; or that Cox had used the opportunity for customers to infringe to lend credibility to the service it offered,” Sauer wrote.

On the vicarious liability question, “there is no conflict among the circuits, which all apply the same financial-benefit requirement to different fact patterns,” Sauer wrote. “Sony has not identified any court of appeals decision that reached a different result on facts similar to those here.”

Cox issued a statement welcoming the US court brief. “We are pleased the solicitor general agrees the Supreme Court should review this significant copyright case that could jeopardize Internet access for all Americans and fundamentally change how Internet service providers manage their networks,” Cox said.

Fun With Veo 3 and Media Generation

Media / Kris Guyer / May 29, 2025

Since Claude 4 Opus things have been refreshingly quiet. Video break!

First up we have Prompt Theory, made with Veo 3, which I am considering the first legitimately good AI-generated video I’ve seen. It perfectly combining form and function. Makes you think.

Here’s a variant, to up the stakes a bit, then here is him doing that again.

What does it say about the medium, or about us, that these are the first legit videos?

This was the second clearly good product. Once again, we see a new form of storytelling emerging, a way to make the most of a series of clips that last a maximum of eight seconds each. The script and execution are fantastic.

I predict that will be the key for making AI videos at the current tech level. You have to have a great script and embrace the style of storytelling that AI can do well. It will be like the new TikTok, except with a higher barrier to entry. At this level, it is fantastic for creatives and creators.

Or you can do this (thread has a bunch more):

Tetraspace: finally we made the most beautiful woman in the world saying I love you from the famous QC short story Don’t Do That.

Sound is a game changer, and within an eight second clip I think we’re definitely ‘there’ with Veo 3 except for having more fine control and editing tools. What we don’t see yet is anyone extending the eight second clips into sixteen second clips (and then more by induction), but it feels like we’re only a few months away from that being viable and then the sky’s the limit.

Is Veo 3 too expensive for ‘personal fun’ uses?

Near Cyan: veo3 is far too pricey to use just for personal fun all the time, so the primary high-volume use case will be for bulk youtube shorts monetization. this is the first time (i think?) an sota genai model provider also owns the resulting distribution of much of what users will make.

For now, basically yes, once you run through your free credits. It’s $21 marginal cost per minute of silent video or $45 with sound, and any given generation might not be what you want. That’s not casual use territory. If you can produce a good two-hour movie for $10k (let’s say you get to use about half the footage?) then that’s obviously great, but yeah you gotta be going for real distribution here.

I predict that sometime soon, someone will make a good Veo 3 rules video, about the existential situation of the actors involved being AI, where the twist is that the video was made by human actors. I also predict that the cost of making this video will be, shall we say, not small in relative terms.

Hasan Can: $0.17 per image for OpenAI’s GPT Image 1 model is insanely expensive. How are developers supposed to use this at scale without going broke? OpenAI seriously needs to cut costs and optimize this model. In its current form, it’s just not viable for indie developers.

Rijn Hartman: INSANELY expensive – I tried building on it and while testing alone is costed $15. Not worth.

Insanely expensive? My lord is this ‘everything is amazing and nobody’s happy.’ You’re getting a complete artistic image for $0.17. Can you imagine you can commission art to your specifications for $0.17? Hot damn. Compare that to the previous options for an indie (game) developer. I get that you might want to use a different option now that’s cheaper, or that you might want to disable your users from using it if you can’t charge. And of course who is to say the images are any good. But we have a huge bug in our understanding of value.

Seb Krier predicts that as AI offers a low cost alternative way to create content, we will see a further bifurcation into high culture versus low culture, between art made to scale in the market and make big bucks, and art made for self-satisfaction and novelty-driven reasons, and both will improve in quality. I’d add we also should see a third category of highly personalized content that can’t scale at all, which seems distinct in many ways from artisan production, and also a split between ‘embrace AI’ versus ‘make a point of in many or all ways avoiding AI.’

Seb thinks all this is good, actually. I think it could be, but I’m highly unsure.

We should beware the further shattering of the cultural commons, for many reasons, and also a lack of sufficient incentives to drive creatives, even if their costs are down. And a lot of this will depend on our ability to use AI or rely on others to do selection. That seems like a highly solvable problem, and we’ve made great strides in solving it for some areas but we still struggle a lot, especially with the inability to make the selection mechanism be maximizing user experience rather than work for a platform.

Another big issue Gwern raises is that ‘bad money crowds out good’ is totally a thing.

Gwen: The higher-order effects here are going to be a problem. You could run the same argument about LLMs: “if you don’t like ChatGPTese creative writing, you don’t have to read it; therefore, everyone is strictly better off for it.”

In the current landscape, does that seem true?

(You might defend it on net, but there are obviously lots of places where things have gotten worse, and there are compounding effects: what is the long run effect on creative writing of all the young people learning to write like ChatGPT, rather than themselves?)

I think we are definitely better off at least for now on both video and text, but yeah there isn’t going to be any getting around it, especially for people who scroll TikTok or Instagram, unless we get good widely distributed AI filtering.

Seb Krier: Yes I don’t think it will be without cost for sure. I think we’re still in the early days and I imagine we’ll come up with more tools, UIs, customisation options, finetuned models, ways of teaching writing, and other tricks that could help incentivise diversity. Some degree of homogenisation is likely but I’m not sure it’s permanent or the only way things go.

Even today I’m finding it boring and bland when I read ChatGPTese and it turns me off from the rest of the text (sometimes). I assume many will feel that way and that might incentivise different styles, particularly in domains where individuality matters.

But it’s true that you might get a lot of slop music and slop art; for those who don’t want it I assume we’ll also get better at developing curation tools and communities. Today even if one doesn’t like Spotify recs, there are so many ways of accessing more interesting music!

Yes, this is true, you can work around Spotify recs being bad, but in practice it is so so much better if the recs that are natural and easy to access are good. Netflix illustrates this even more clearly, yes you can in theory do a search for anything you want, but who will do that? How they organize your list and recommendations determines (I think?) most of what most people watch.

Until Veo 3, nothing anyone made with AI video was interesting to me as more than a curiosity. Now, we have a few good meta things. Soon, it’s going beyond that.

Also, in sort of related news, here’s a funny thing that happened this week:

Anthropic’s Long Term Benefits Trust appoints Reed Hastings, chairman and cofounder of Netflix, to Anthropic’s board. That’s certainly a heavy hitter, he clearly does worry about AI and has written a $50 million check to prove it. The only worry is that his concerns could be too focused on the mundane.

Also I’d love to see a Netflix-Anthropic partnership, Claude giving me my Netflix recommendations and having full access to their catalogue with subscription when?

Elon Musk: There is an 80 percent chance Starship’s engine bay issues are solved

elon musk, Mars, Space, spacex / Kris Guyer / May 28, 2025

Ars: Ten years ago you kind of made big bets on Starship and Starlink, and most people probably expected one or both of them to fail.

Musk: Including me.

Ars: Yeah. These were huge bets.

Musk: I was interviewed in the early days of Starlink, and they were asking me what’s the goal of Starlink? I said goal number one: don’t go bankrupt, as every other [low-Earth orbit] communications constellation has gone bankrupt, and we don’t want to join them in the cemetery. So any outcome that does not result in death would be a good outcome.

Ars: Starlink has become really successful. It helped me during a hurricane. And Starship is coming along. As you look out for the next 10 years, what are you betting on big now that will really bear fruit for SpaceX a decade from now?

Musk: Well, by far the biggest thing is Starship. If the Starship program is successful—and we see a path to success—it’s just a question of when we will have created the first fully reusable orbital launch vehicle, which is the holy grail of rocketry, as you know. So no one has ever made a fully reusable orbital vehicle, and even the parts that have been reusable have been extremely arduous to reuse, such that the economics actually were worse than an expendable rocket in a lot of cases. The canonical example being the shuttle, where the shuttle’s fully loaded, cost of the whole program, I believe, was about a billion dollars a flight.

Ars: I saw one research paper that estimated the fully loaded cost was about $1.5 billion.

Musk. Yeah. And that is roughly equivalent to a Saturn V cost. But the Saturn V as an expendable rocket had four times the payload capacity of the shuttle. So the shuttle was like the principle of reusability was a good one, but the execution, unfortunately, was not. The shuttle got burdened by so many crazy requirements. You know, I’ve got this five-step first principles process thing for making things better. And step one of my five-step process is make the requirements less dumb. And for the government, it’s the opposite. The government is making requirements more dumb.

Ars: So getting a rapid and reusable Starship is the main goal for SpaceX over the next 5 to 10 years?

Musk: Yeah, absolutely.

Ars: You’ve been in the space industry now for almost 25 years. And in that time, SpaceX has gone a long way toward solving launch. So if you were coming into the industry today as a 20-something, you know, with a couple $100 million, what would be the problem you would want to solve? What should new companies, philanthropists, and others be working on in space?

Musk: We’re building the equivalent of the Union Pacific Railroad and the train. So once you have the transportation system to Mars, then there’s a vast set of opportunities that open up to do anything on the surface of Mars, which includes, you know, doing everything from building a semiconductor fab to a pizza joint, basically building a civilization. So we want to solve the transport problem, and that can enable philanthropists and entrepreneurs to do things on Mars, which is everything needed for civilization. Look at, say, California. There were very few people in California until the Union Pacific was completed, and then California became the most populous state in the nation. And look at Silicon Valley and Hollywood and everything. So that’s our goal. We want to get people there, and if we can get people there, then there’s a literal world of opportunity.

Where hyperscale hardware goes to retire: Ars visits a very big ITAD site

The details of each unit—CPU, memory, HDD size—are taken down and added to the asset tag, and the device is sent on to be physically examined. This step is important because “many a concealed drive finds its way into this line,” Kent Green, manager of this site, told me. Inside the machines coming from big firms, there are sometimes little USB, SD, SATA, or M.2 drives hiding out. Some were make-do solutions installed by IT and not documented, and others were put there by employees tired of waiting for more storage. “Some managers have been pretty surprised when they learn what we found,” Green said.

With everything wiped and with some sense of what they’re made of, each device gets a rating. It’s a three-character system, like “A-3-6,” based on function, cosmetic condition, and component value. Based on needs, trends, and other data, devices that are cleared for resale go to either wholesale, retail, component harvesting, or scrap.

Full-body laptop skins

If a device has retail value, it heads into a section of this giant facility where workers do further checks. Automated software plays sounds on the speakers, checks that every keyboard key is sending signals, and checks that laptop batteries are at 80 percent capacity or better. At the end of the line is my favorite discovery: full-body laptop skins.

Some laptops—certain Lenovo, Dell, and HP models—are so ubiquitous in corporate fleets that it’s worth buying an adhesive laminating sticker in their exact shape. They’re an uncanny match for the matte black, silver, and slightly less silver finishes of the laptops, covering up any blemishes and scratches. Watching one of the workers apply this made me jealous of their ability to essentially reset a laptop’s condition (so one could apply whole new layers of swag stickers, of course). Once rated, tested, and stickered, laptops go into a clever “cradle” box, get the UN 3481 “battery inside” sticker, and can be sold through retail.

200 mph for 500 miles: How IndyCar drivers prepare for the big race

Cars, Features, Indianapolis 500, Indy 500, IndyCar, racing, simulation / Kris Guyer / May 25, 2025

Andretti Global’s Kyle Kirkwood and Marcus Ericsson talk to us about the Indy 500.

This coming weekend is a special one for most motorsport fans. There are Formula 1 races in Monaco and NASCAR races in Charlotte. And arguably towering over them both is the Indianapolis 500, being held this year for the 109th time. America’s oldest race is also one of its toughest: The track may have just four turns, but the cars negotiate them going three times faster than you drive on the highway, inches from the wall. For hours. At least at Le Mans, you have more than one driver per car.

This year’s race promises to be an exciting one. The track is sold out for the first time since the centenary race in 2016. A rookie driver and a team new to the series took pole position. Two very fast cars are starting at the back thanks to another conflict-of-interest scandal involving Team Penske, the second in two years for a team whose owner also owns the track and the series. And the cars are trickier to drive than they have been for many years, thanks to a new supercapacitor-based hybrid system that has added more than 100 lbs to the rear of the car, shifting the weight distribution further back.

Ahead of Sunday’s race, I spoke with a couple of IndyCar drivers and some engineers to get a better sense of how they prepare and what to expect.

Concentrate

It all comes “from months of preparation,” said Marcus Ericsson, winner of the race in 2022 and one of Andretti Global’s drivers in this year’s event. “When we get here to the month of May, it’s just such a busy month. So you’ve got to be prepared mentally—and basically before you get to the month of May because if you start doing it now, it’s too late,” he told me.

The drivers spend all month at the track, with a race on the road course earlier this month. Then there’s testing on the historic oval, followed by qualifying last weekend and the race this coming Sunday. “So all those hours you put in in the winter, really, and leading up here to the month of May—it’s what pays off now,” Ericsson said. That work involved multiple sessions of physical training each week, and Ericsson says he also does weekly mental coaching sessions.

“This is a mental challenge,” Ericsson told me. “Doing those speeds with our cars, you can’t really afford to have a split second of loss of concentration because then you might be in the wall and your day is over and you might hurt yourself.”

When drivers get tired or their focus slips, that’s when mistakes happen, and a mistake at Indy often has consequences.

Simulate

Being mentally and physically prepared is part of it. It also helps if you can roll the race car off the transporter and onto the track with a setup that works rather than spending the month chasing the right combination of dampers, springs, wing angles, and so on. And these days, that means a lot of simulation testing.

The multi-axis driver in the loop simulators might look like just a very expensive video game, but these multimillion-dollar setups aren’t about having fun. “Everything that you are feeling or changing in the sim is ultimately going to reflect directly to what happens on track,” explained Kyle Kirkwood, teammate to Ericsson at Andretti Global and one of only two drivers to have won an Indycar race in 2025.

Andretti, like the other teams using Honda engines, uses the new HRC simulator in Indiana. “And yes, it’s a very expensive asset, but it’s also likely cheaper than going to the track and doing the real thing,” Kirkwood said. “And it’s a much more controlled environment than being at the track because temperature changes or track conditions or wind direction play a huge factor with our car.”

A high degree of correlation between the simulation and the track is what makes it a powerful tool. “We run through a sim, and you only get so many opportunities, especially at a place like Indianapolis, where you go from one day to the next and the temperature swings, or the wind conditions, or whatever might change drastically,” Kirkwood said. “You have to be able to sim it and be confident with the sim that you’re running to go out there and have a similar balance or a similar performance.”

“So you have to make adjustments, whether it’s a spring rate, whether it’s keel ballast or just overall, maybe center of pressure, something like that,” Kirkwood said. “You have to be able to adjust to it. And that’s where the sim tool comes in play. You move the weight balance back, and you’re like, OK, now what happens with the balance? How do I tune that back in? And you run that all through the sim, and for us, it’s been mirror-perfect going to the track when we do that.”

More impressively, a lot of that work was done months ago. “I would say most of it, we got through it before the start of this season,” Kirkwood said. “Once we get into the season, we only get a select few days because every Honda team has to run on the same simulator. Of course, it’s different with the engineering sim; those are running nonstop.”

Sims are for engineers, too

An IndyCar team is more than just its drivers—”the spacer between the seat and the wheel,” according to Kirkwood—and the engineers rely heavily on sim work now that real-world testing is so highly restricted. And they use a lot more than just driver-in-the-loop (DiL).

“Digital simulation probably goes to a higher level,” explained Scott Graves, engineering manager at Andretti Global. “A lot of the models we develop work in the DiL as well as our other digital tools. We try to develop universal models, whether that’s tire models, engine models, or transmission models.”

“Once you get into to a fully digital model, then I think your optimization process starts kicking in,” Graves said. “You’re not just changing the setting and running a pretend lap with a driver holding a wheel. You’re able to run through numerous settings and optimization routines and step through a massive number of permutations on a car. Obviously, you’re looking for better lap times, but you’re also looking for fuel efficiency and a lot of other parameters that go into crossing the finish line first.”

As an example, Graves points to the dampers. “The shock absorber is a perfect example where that’s a highly sophisticated piece of equipment on the car and it’s very open for team development. So our cars have fully customized designs there that are optimized for how we run the car, and they may not be good on another team’s car because we’re so honed in on what we’re doing with the car,” he said.

“The more accurate a digital twin is, the more we are able to use that digital twin to predict the performance of the car,” said David Taylor, VP of industry strategy at Siemens DISW, which has partnered with Andretti for some years now. “It will never be as complete and accurate as we want it to be. So it’s a continuous pursuit, and we keep adding technology to our portfolio and acquiring companies to try to provide more and more tools to people like Scott so they can more accurately predict that performance.”

What to expect on Sunday?

Kirkwood was bullish about his chances despite starting relatively deep in the field, qualifying in 23rd place. “We’ve been phenomenal in race trim and qualifying,” he said. “We had a bit of a head-scratcher if I’m being honest—I thought we would definitely be a top-six contender, if not a front row contender, and it just didn’t pan out that way on Saturday qualifying.”

“But we rolled back out on Monday—the car was phenomenal. Once again, we feel very, very racy in traffic, which is a completely different animal than running qualifying,” Kirkwood said. “So I’m happy with it. I think our chances are good. We’re starting deep in the field, but so are a lot of other drivers. So you can expect a handful of us to move forward.”

The more nervous hybrid IndyCars with their more rearward weight bias will probably result in more cautions, according to Ericsson, who will line up sixth for the start of the race on Sunday.

“Whereas in previous years you could have a bit of a moment and it would scare you, you usually get away with it,” he said. “This year, if you have a moment, it usually ends up with you being in the fence. I think that’s why we’ve seen so many crashes this year—because a pendulum effect from the rear of the car that when you start losing it, this is very, very difficult or almost impossible to catch.”

“I think it’s going to mean that the race is going to be quite a few incidents with people making mistakes,” Ericsson said. “In practice, if your car is not behaving well, you bring it to the pit lane, right? You can do adjustments, whereas in the race, you have to just tough it out until the next pit stop and then make some small adjustments. So if you have a bad car at the start a race, it’s going to be a tough one. So I think it’s going to be a very dramatic and entertaining race.”

SteamOS 3.7 brings Valve’s gaming OS to other handhelds and generic AMD PCs

asus rog ally, asus rog ally x, gaming, lenovo legion go, steam deck, steamos, Tech, valve / Kris Guyer / May 25, 2025

Valve’s instructions will walk you through downloading a SteamOS recovery image and copying it to a USB drive using either the Rufus tool (on Windows) or Balena Etcher (the preferred macOS and Linux utility). After turning Secure Boot off, you should be able to boot from the USB drive and install SteamOS as you would on a regular Steam Deck.

Note that there’s no simple, officially supported way to dual-boot SteamOS and Windows; if you decide to turn your handheld, laptop, or desktop into a new Steam Machine, the only way to make it back into a Windows PC is to re-enable Secure Boot and install a fresh copy from another USB drive.

The SteamOS 3.7 update (officially, version 3.7.8) also includes a bunch of other updates to the underlying software: version 6.11 of the Linux kernel (up from version 6.5 in SteamOS 3.6), “a newer Arch Linux base,” version 6.2.5 of the Plasma interface in desktop mode, new Mesa graphics drivers, and various other tweaks and bug fixes.

A second act for SteamOS

The original version of SteamOS was designed to be widely compatible with all kinds of PC hardware and was available both from major PC manufacturers and as a standalone OS that you could (and which we did) install on custom, self-built PCs. But these computers and that version of SteamOS mostly flopped, at least in part because they only ran a small subset of games that natively supported Linux.

The current version of SteamOS launched with more modest aims as the first-party operating system for a single piece of hardware. But by focusing on the game compatibility problem first and leading the way with category-defining hardware, Valve has actually built a much stronger foundation for the current version of SteamOS than it did for the original.

That doesn’t make SteamOS a drop-in replacement for Windows—without strong support for Intel or Nvidia hardware, it’s not a great candidate for the majority of gaming PCs, or even Intel-powered gaming handhelds like the MSI Claw A1M. And Windows is set up to be a multipurpose general-use operating system in ways that SteamOS isn’t; Valve still says that, despite the presence of desktop mode, “users should not consider SteamOS as a replacement for their desktop operating system.” But for certain kinds of systems that are primarily used as gaming PCs, SteamOS is a real contender.

Uncertainty loomed as FDA advisors met to discuss this year’s COVID shot

annual shots, COVID-19, fda, health, seasonal shots, vaccines / Kris Guyer / May 25, 2025

Calling it a “practical question,” he asked, “If we were to change strains, can we assume that age-specific licensure won’t change for any of these [vaccine] products?” Currently, COVID-19 boosters are accessible to those aged 6 months and up.

Weir reiterated that there was no answer. Another FDA official, David Kaslow, chimed in to say only, “Rest assured that we’re engaging with the manufacturers on this topic.”

As a follow-up to that exchange, VRBPAC member and infectious disease expert Eric Rubin of Harvard University shot down the FDA’s plan to use randomized placebo-controlled trials for licensure for healthy children and adults. The plethora of observational data—aka real-world data—on the boosters shows clear efficacy, Rubin pointed out. That suggests that requiring people in a trial to take placebos despite the availability of a clearly effective treatment could be unethical.

It suggests “that a randomized controlled trial (RCT) has no equipoise right now, and that you cannot do one,” Rubin said. “I don’t think the RCT is feasible,” he added.

The selection

While the pushback and the questions lingered, the committee still had to select a strain. For now, omicron still reigns, and variants in the JN.1 lineage are still dominant. That is largely unchanged from last year, when vaccine makers were advised to target their seasonal shots against the JN.1 lineage generally, or KP.2, the leading variant in the JN.1 lineage at the time, specifically.

This year, advisors unanimously voted to stick with vaccines that target the JN.1 lineage, in line with recommendations from the World Health Organization. The question of targeting the JN.1 lineage was the only voting question the FDA tasked them with. But there was open discussion on a more specific recommendation. Given the regulatory uncertainty, advisors were divided on whether to stick with the JN.1 and KP.2 formulations from last year or recommend switching to the latest leading variant in the JN.1 family, LP.8.1.

Shortly after the meeting, the FDA announced that it would essentially leave it up to manufacturers; they could stick with JN.1 or KP.2 but, if feasible, switch to LP.8.1.

“The COVID-19 vaccines for use in the United States beginning in fall 2025 should be monovalent JN.1-lineage-based COVID-19 vaccines (2025–2026 Formula), preferentially using the LP.8.1 strain,” it said.

Ammonia aerosols from penguin guano likely play a part in the formation of heat-shielding clouds.

New research shows that penguin guano in Antarctica is an important source of ammonia aerosol particles that help drive the formation and persistence of low clouds, which cool the climate by reflecting some incoming sunlight back to space.

The findings reinforce the growing awareness that Earth’s intricate web of life plays a significant role in shaping the planetary climate. Even at the small levels measured, the ammonia particles from the guano interact with sulfur-based aerosols from ocean algae to start a chemical chain reaction that forms billions of tiny particles that serve as nuclei for water vapor droplets.

The low marine clouds that often cover big tracts of the Southern Ocean around Antarctica are a wild card in the climate system because scientists don’t fully understand how they will react to human-caused heating of the atmosphere and oceans. One recent study suggested that the big increase in the annual global temperature during 2023 and 2024 that has continued into this year was caused in part by a reduction of that cloud cover.

“I’m constantly surprised at the depth of how one small change affects everything else,” said Matthew Boyer, a coauthor of the new study and an atmospheric scientist at the University of Helsinki’s Institute for Atmospheric and Earth System Research. “This really does show that there is a deep connection between ecosystem processes and the climate. And really, it’s the synergy between what’s coming from the oceans, from the sulfur-producing species, and then the ammonia coming from the penguins.”

Climate survivors

Aquatic penguins evolved from flying birds about 60 million years ago, shortly after the age of dinosaurs, and have persisted through multiple, slow, natural cycles of ice ages and warmer interglacial eras, surviving climate extremes by migrating to and from pockets of suitable habitat, called climate refugia, said Rose Foster-Dyer, a marine and polar ecologist with the University of Canterbury in New Zealand.

A 2018 study that analyzed the remains of an ancient “super colony” of the birds suggests there may have been a “penguin optimum” climate window between about 4,000 and 2,000 years ago, at least for some species in some parts of Antarctica, she said. Various penguin species have adapted to different habitat niches and this will face different impacts caused by human-caused warming, she said.

Foster-Dyer has recently done penguin research around the Ross Sea, and said that climate change could open more areas for land-breeding Adélie penguins, which don’t breed on ice like some other species.

“There’s evidence that this whole area used to have many more colonies … which could possibly be repopulated in the future,” she said. She is also more optimistic than some scientists about the future for emperor penguins, the largest species of the group, she added.

“They breed on fast ice, and there’s a lot of publications coming out about how the populations might be declining and their habitat is hugely threatened,” she said. “But they’ve lived through so many different cycles of the climate, so I think they’re more adaptable than people currently give them credit for.”

In total, about 20 million breeding pairs of penguins nest in vast colonies all around the frozen continent. Some of the largest colonies, with up to 1 million breeding pairs, can cover several square miles.There aren’t any solid estimates for the total amount of guano produced by the flightless birds annually, but some studies have found that individual colonies can produce several hundred tons. Several new penguin colonies were discovered recently when their droppings were spotted in detailed satellite images.

A few penguin colonies have grown recently while others appear to be shrinking, but in general, their habitat is considered threatened by warming and changing ice conditions, which affects their food supplies. The speed of human-caused warming, for which there is no precedent in paleoclimate records, may exacerbate the threat to penguins, which evolve slowly compared to many other species, Foster-Dyer said.

“Everything’s changing at such a fast rate, it’s really hard to say much about anything,” she said.

Recent research has shown how other types of marine life are also important to the global climate system. Nutrients from bird droppings help fertilize blooms of oxygen-producing plankton, and huge swarms of fish that live in the middle layers of the ocean cycle carbon vertically through the water, ultimately depositing it in a generally stable sediment layer on the seafloor.

Tricky measurements

Boyer said the new research started as a follow-up project to other studies of atmospheric chemistry in the same area, near the Argentine Marambio Base on an island along the Antarctic Peninsula. Observations by other teams suggested it could be worth specifically trying to look at ammonia, he said.

Boyer and the other scientists set up specialized equipment to measure the concentration of ammonia in the air from January to March 2023. They found that, when the wind blew from the direction of a colony of about 60,000 Adélie penguins about 5 miles away, the ammonia concentration increased to as high as 13.5 parts per billion—more than 1,000 times higher than the background reading. Even after the penguins migrated from the area toward the end of February, the ammonia concentration was still more than 100 times as high as the background level.

“We have one instrument that we use in the study to give us the chemistry of gases as they’re actually clustering together,” he said.

“In general, ammonia in the atmosphere is not well-measured because it’s really difficult to measure, especially if you want to measure at a very high sensitivity, if you have low concentrations like in Antarctica,” he said.

Penguin-scented winds

The goal was to determine where the ammonia is coming from, including testing a previous hypothesis that the ocean surface could be the source, he said.

But the size of the penguin colonies made them the most likely source.

“It’s well known that sea birds give off ammonia. You can smell them. The birds stink,” he said. “But we didn’t know how much there was. So what we did with this study was to quantify ammonia and to quantify its impact on the cloud formation process.”

The scientists had to wait until the wind blew from the penguin colony toward the research station.

“If we’re lucky, the wind blows from that direction and not from the direction of the power generator,” he said. “And we were lucky enough that we had one specific event where the winds from the penguin colony persisted long enough that we were actually able to track the growth of the particles. You could be there for a year, and it might not happen.”

The ammonia from the guano does not form the particles but supercharges the process that does, Boyer said.

“It’s really the dimethyl sulfide from phytoplankton that gives off the sulfur,” he said. “The ammonia enhances the formation rate of particles. Without ammonia, sulfuric acid can form new particles, but with ammonia, it’s 1,000 times faster, and sometimes even more, so we’re talking up to four orders of magnitude faster because of the guano.”

This is important in Antarctica specifically because there are not many other sources of particles, such as pollution or emissions from trees, he added.

“So the strength of the source matters in terms of its climate effect over time,” he said. “And if the source changes, it’s going to change the climate effect.”

It will take more research to determine if penguin guano has a net cooling effect on the climate. But in general, he said, if the particles transport out to sea and contribute to cloud formation, they will have a cooling effect.

“What’s also interesting,” he said, “is if the clouds are over ice surfaces, it could actually lead to warming because the clouds are less reflective than the ice beneath.” In that case, the clouds could actually reduce the amount of heat that brighter ice would otherwise reflect away from the planet. The study did not try to measure that effect, but it could be an important subject for future research, he added.

The guano effect lingers even after the birds leave the breeding areas. A month after they were gone, Boyer said ammonia levels in the air were still 1,000 times higher than the baseline.

“The emission of ammonia is a temperature-dependent process, so it’s likely that once wintertime comes, the ammonia gets frozen in,” he said. “But even before the penguins come back, I would hypothesize that as the temperature warms, the guano starts to emit ammonia again. And the penguins move all around the coast, so it’s possible they’re just fertilizing an entire coast with ammonia.”

Google’s Will Smith double is better at eating AI spaghetti … but it’s crunchy?

AI, Ai video generator, Biz & IT, Deepfakes, Google, Google Veo, machine learning, Spaghetti, Veo, Veo 3, video synthesis, will smith / Kris Guyer / May 24, 2025

On Tuesday, Google launched Veo 3, a new AI video synthesis model that can do something no major AI video generator has been able to do before: create a synchronized audio track. While from 2022 to 2024, we saw early steps in AI video generation, each video was silent and usually very short in duration. Now you can hear voices, dialog, and sound effects in eight-second high-definition video clips.

Shortly after the new launch, people began asking the most obvious benchmarking question: How good is Veo 3 at faking Oscar-winning actor Will Smith at eating spaghetti?

First, a brief recap. The spaghetti benchmark in AI video traces its origins back to March 2023, when we first covered an early example of horrific AI-generated video using an open source video synthesis model called ModelScope. The spaghetti example later became well-known enough that Smith parodied it almost a year later in February 2024.

Here’s what the original viral video looked like:

One thing people forget is that at the time, the Smith example wasn’t the best AI video generator out there—a video synthesis model called Gen-2 from Runway had already achieved superior results (though it was not yet publicly accessible). But the ModelScope result was funny and weird enough to stick in people’s memories as an early poor example of video synthesis, handy for future comparisons as AI models progressed.

AI app developer Javi Lopez first came to the rescue for curious spaghetti fans earlier this week with Veo 3, performing the Smith test and posting the results on X. But as you’ll notice below when you watch, the soundtrack has a curious quality: The faux Smith appears to be crunching on the spaghetti.

On X, Javi Lopez ran “Will Smith eating spaghetti” in Google’s Veo 3 AI video generator and received this result.

It’s a glitch in Veo 3’s experimental ability to apply sound effects to video, likely because the training data used to create Google’s AI models featured many examples of chewing mouths with crunching sound effects. Generative AI models are pattern-matching prediction machines, and they need to be shown enough examples of various types of media to generate convincing new outputs. If a concept is over-represented or under-represented in the training data, you’ll see unusual generation results, such as jabberwockies.

US solar keeps surging, generating more power than hydro in 2025

coal, Energy, hydro, natural gas, Science, solar, Wind / Kris Guyer / May 24, 2025

Under those circumstances, the rest of the difference will be made up for with fossil fuels. Running counter to recent trends, the use of natural gas dropped during the first three months of 2025. This means that the use of coal rose nearly as quickly as demand, up by 23 percent compared to the same time period in 2024.

Despite the rise in coal use, the fraction of carbon-free electricity held steady year over year, with wind/solar/hydro/nuclear accounting for 43 percent of all power put on the US grid. That occurred despite small drops in nuclear and hydro production.

Solar power also passed a key milestone in 2025, although it requires digging through the statistics to realize it. In terms of power on the grid, there was less solar than hydro. But the Energy Information Agency also estimates the production from small-scale solar, like the kind you’d find on people’s roofs. Some of this never enters the grid and instead simply offsets demand locally (in that it gets used by the house that sits beneath the panels). If you combine the TW-hr produced by small- and grid-scale solar, however, they surpass the production from hydropower by a significant margin.

This surge in solar comes on top of a 30 percent increase in production the year prior. The growth curve is clearly not slowing down.

That dynamic is also not likely to change immediately in response to cuts to tax breaks for renewable power that were part of the budget package passed by the House of Representatives on Thursday, and not only because some Republican senators might object to budget changes that will harm their states. Solar power in most areas is now cheaper than alternatives, even without subsidies, and any power plant (renewable or otherwise) will likely see its costs rise due to the tariff environment. Finally, the tax breaks don’t expire immediately, and most power plant construction requires significant advanced planning.

All of those factors should continue the solar boom for at least a couple more years before all of the expected changes apply the brakes.

Rocket Report: SpaceX’s expansion at Vandenberg; India’s PSLV fails in flight

rocket report, Science, Space / Kris Guyer / May 23, 2025

China’s diversity in rockets was evident this week, with four types of launchers in action.

Welcome to Edition 7.45 of the Rocket Report! Let’s talk about spaceplanes. Since the Space Shuttle, spaceplanes have, at best, been a niche part of the space transportation business. The US Air Force’s uncrewed X-37B and a similar vehicle operated by China’s military are the only spaceplanes to reach orbit since the last shuttle flight in 2011, and both require a lift from a conventional rocket. Virgin Galactic’s suborbital space tourism platform is also a spaceplane of sorts. A generation or two ago, one of the chief arguments in favor of spaceplanes was that they were easier to recover and reuse. Today, SpaceX routinely reuses capsules and rockets that look much more like conventional space vehicles than the winged designs of yesteryear. Spaceplanes are undeniably alluring in appearance, but they have the drawback of carrying extra weight (wings) into space that won’t be used until the final minutes of a mission. So, do they have a future?

Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

One of China’s commercial rockets returns to flight. The Kinetica-1 rocket launched Wednesday for the first time since a failure doomed its previous attempt to reach orbit in December, according to the vehicle’s developer and operator, CAS Space. The Kinetica-1 is one of several small Chinese solid-fueled launch vehicles managed by a commercial company, although with strict government oversight and support. CAS Space, a spinoff of the Chinese Academy of Sciences, said its Kinetica-1 rocket deployed multiple payloads with “excellent orbit insertion accuracy.” This was the seventh flight of a Kinetica-1 rocket since its debut in 2022.

Back in action … “Kinetica-1 is back!” CAS Space posted on X. “Mission Y7 has just successfully sent six satellites into designated orbits, making a total of 63 satellites or 6 tons of payloads since its debut. Lots of missions are planned for the coming months. 2025 is going to be awesome.” The Kinetica-1 is designed to place up to 2 metric tons of payload into low-Earth orbit. A larger liquid-fueled rocket, Kinetica-2, is scheduled to debut later this year.

French government backs a spaceplane startup. French spaceplane startup AndroMach announced May 15 that it received a contract from CNES, the French space agency, to begin testing an early prototype of its Banger v1 rocket engine, European Spaceflight reports. Founded in 2023, AndroMach is developing a pair of spaceplanes that will be used to perform suborbital and orbital missions to space. A suborbital spaceplane will utilize turbojet engines for horizontal takeoff and landing, and a pressure-fed biopropane/liquid oxygen rocket engine to reach space. Test flights of this smaller vehicle will begin in early 2027.

A risky proposition … A larger ÉTOILE “orbital shuttle” is designed to be launched by various small launch vehicles and will be capable of carrying payloads of up to 100 kilograms (220 pounds). According to the company, initial test flights of ÉTOILE are expected to begin at the beginning of the next decade. It’s unclear how much CNES is committing to AndroMach through this contract, but the company says the funding will support testing of an early demonstrator for its propane-fueled engine, with a focus on evaluating its thermodynamic performance. It’s good to see European governments supporting developments in commercial space, but the path to a small commercial orbital spaceplane is rife with risk. (submitted by EllPeaTea)

Dawn Aerospace is taking orders. Another spaceplane company in a more advanced stage of development says it is now taking customer orders for flights to the edge of space. New Zealand-based Dawn Aerospace said it is beginning to take orders for its remotely piloted, rocket-powered suborbital spaceplane, known as Aurora, with first deliveries expected in 2027, Aviation Week & Space Technology reports. “This marks a historic milestone: the first time a space-capable vehicle—designed to fly beyond the Kármán line (100 kilometers or 328,000 feet)—has been offered for direct sale to customers,” Dawn Aerospace said in a statement. While it hasn’t yet reached space, Dawn’s Aurora spaceplane flew to supersonic speed for the first time last year and climbed to an altitude of 82,500 feet (25.1 kilometers), setting a record for the fastest climb from a runway to 20 kilometers.

Further along … Aurora is small in stature, measuring just 15.7 feet (4.8 meters) long. It’s designed to loft a payload of up to 22 pounds (10 kilograms) above the Kármán line for up to three minutes of microgravity, before returning to a runway landing. Eventually, Dawn wants to reduce the turnaround time between Aurora flights to less than four hours. “Aurora is set to become the fastest and highest-flying aircraft ever to take off from a conventional runway, blending the extreme performance of rocket propulsion with the reusability and operational simplicity of traditional aviation,” Dawn said. The company’s business model is akin to commercial airlines, where operators can purchase an aircraft directly from a manufacturer and manage their own operations. (submitted by EllPeaTea)

India’s workhorse rocket falls short of orbit. In a rare setback, Indian Space Research Organisation’s (ISRO) launch vehicle PSLV-C61 malfunctioned and failed to place a surveillance satellite into the intended orbit last weekend, the Times of India reported. The Polar Satellite Launch Vehicle lifted off from a launch pad on the southeastern coast of India early Sunday, local time, with a radar reconnaissance satellite named EOS-09, or RISAT-1B. The satellite was likely intended to gather intelligence for the Indian military. “The country’s military space capabilities, already hindered by developmental challenges, have suffered another setback with the loss of a potential strategic asset,” the Times of India wrote.

What happened? … V. Narayanan, ISRO’s chairman, later said that the rocket’s performance was normal until the third stage. The PSLV’s third stage, powered by a solid rocket motor, suffered a “fall in chamber pressure” and the mission could not be accomplished, Narayanan said. Investigators are probing the root cause of the failure. Telemetry data indicated the rocket deviated from its planned flight path around six minutes after launch, when it was traveling more than 12,600 mph (5.66 kilometers per second), well short of the speed it needed to reach orbital velocity. The rocket and its payload fell into the Indian Ocean south of the launch site. This was the first PSLV launch failure in eight years, ending a streak of 21 consecutive successful flights.

SES makes a booking with Impulse Space. SES, owner of the world’s largest fleet of geostationary satellites, plans to use Impulse Space’s Helios kick stage to take advantage of lower-cost, low-Earth-orbit (LEO) launch vehicles and get its satellites quickly into higher orbits, Aviation Week & Space Technology reports. SES hopes the combination will break a traditional launch conundrum for operators of medium-Earth-orbit (MEO) and geostationary orbit (GEO). These operators often must make a trade-off between a lower-cost launch that puts them farther from their satellite’s final orbit, or a more expensive launch that can expedite their satellite’s entry into service.

A matter of hours … On Thursday, SES and Impulse Space announced a multi-launch agreement to use the methane-fueled Helios kick stage. “The first mission, currently planned for 2027, will feature a dedicated deployment from a medium-lift launcher in LEO, followed by Helios transferring the 4-ton-class payload directly to GEO within eight hours of launch,” Impulse said in a statement. Typically, this transit to GEO takes several weeks to several months, depending on the satellite’s propulsion system. “Today, we’re not only partnering with Impulse to bring our satellites faster to orbit, but this will also allow us to extend their lifetime and accelerate service delivery to our customers,” said Adel Al-Saleh, CEO of SES. “We’re proud to become Helios’ first dedicated commercial mission.”

Unpacking China’s spaceflight patches. There’s a fascinating set of new patches Chinese officials released for a series of launches with top-secret satellites over the last two months, Ars reports. These four patches depict Buddhist gods with a sense of artistry and sharp colors that stand apart from China’s previous spaceflight emblems, and perhaps—or perhaps not—they can tell us something about the nature of the missions they represent. The missions launched so-called TJS satellites toward geostationary orbit, where they most likely will perform missions in surveillance, signals intelligence, or missile warning.

Making connections … It’s not difficult to start making connections between the Four Heavenly Gods and the missions that China’s TJS satellites likely carry out in space. A protector with an umbrella? An all-seeing entity? This sounds like a possible link to spy craft or missile warning, but there’s a chance Chinese officials approved the patches to misdirect outside observers, or there’s no connection at all.

China aims for an asteroid. China is set to launch its second Tianwen deep space exploration mission late May, targeting both a near-Earth asteroid and a main belt comet, Space News reports. The robotic Tianwen-2 spacecraft is being integrated with a Long March 3B rocket at the Xichang Satellite Launch Center in southwest China, the country’s top state-owned aerospace contractor said. Airspace closure notices indicate a four-hour-long launch window opening at noon EDT (16: 00–20: 00 UTC) on May 28. Backup launch windows are scheduled for May 29 and 30.

New frontiers … Tianwen-2’s first goal is to collect samples from a near-Earth asteroid designated 469219 Kamoʻoalewa, or 2016 HO3, and return them to Earth in late 2027 with a reentry module. The Tianwen-2 mothership will then set a course toward a comet for a secondary mission. This will be China’s first sample return mission from beyond the Moon. The asteroid selected as the target for Tianwen-2 is believed by scientists to be less than 100 meters, or 330 feet, in diameter, and may be made of material thrown off the Moon some time in its ancient past. Results from Tianwen-2 may confirm that hypothesis. (submitted by EllPeaTea)

Upgraded methalox rocket flies from Jiuquan. Another one of China’s privately funded launch companies achieved a milestone this week. Landspace launched an upgraded version of its Zhuque-2E rocket Saturday from the Jiuquan launch base in northwestern China, Space News reports. The rocket delivered six satellites to orbit for a range of remote sensing, Earth observation, and technology demonstration missions. The Zhuque-2E is an improved version of the Zhuque-2, which became the first liquid methane-fueled rocket in the world to reach orbit in 2023.

Larger envelope … This was the second flight of the Zhuque-2E rocket design, but the first to utilize a wider payload fairing to provide more volume for satellites on their ride into space. The Zhuque-2E is a stepping stone toward a much larger rocket Landspace is developing called the Zhuque-3, a stainless steel launcher with a reusable first stage booster that, at least outwardly, bears some similarities to SpaceX’s Falcon 9.

FAA clears SpaceX for Starship Flight 9. The Federal Aviation Administration gave the green light Thursday for SpaceX to launch the next test flight of its Starship mega-rocket as soon as next week, following two consecutive failures earlier this year, Ars reports. The failures set back SpaceX’s Starship program by several months. The company aims to get the rocket’s development back on track with the upcoming launch, Starship’s ninth full-scale test flight since its debut in April 2023. Starship is central to SpaceX’s long-held ambition to send humans to Mars and is the vehicle NASA has selected to land astronauts on the Moon under the umbrella of the government’s Artemis program.

Targeting Tuesday, for now … In a statement Thursday, the FAA said SpaceX is authorized to launch the next Starship test flight, known as Flight 9, after finding the company “meets all of the rigorous safety, environmental and other licensing requirements.” SpaceX has not confirmed a target launch date for the next launch of Starship, but warning notices for pilots and mariners to steer clear of hazard areas in the Gulf of Mexico suggest the flight might happen as soon as the evening of Tuesday, May 27. The rocket will lift off from Starbase, Texas, SpaceX’s privately owned spaceport near the US-Mexico border. The FAA’s approval comes with some stipulations, including that the launch must occur during “non-peak” times for air traffic and a larger closure of airspace downrange from Starbase.

Space Force is fed up with Vulcan delays. In recent written testimony to a US House of Representatives subcommittee that oversees the military, the senior official responsible for purchasing launches for national security missions blistered one of the country’s two primary rocket providers, Ars reports. The remarks from Major General Stephen G. Purdy, acting assistant secretary of the Air Force for Space Acquisition and Integration, concerned United Launch Alliance and its long-delayed development of the large Vulcan rocket. “The ULA Vulcan program has performed unsatisfactorily this past year,” Purdy said in written testimony during a May 14 hearing before the House Armed Services Committee’s Subcommittee on Strategic Forces. This portion of his testimony did not come up during the hearing, and it has not been reported publicly to date.

Repairing trust … “Major issues with the Vulcan have overshadowed its successful certification resulting in delays to the launch of four national security missions,” Purdy wrote. “Despite the retirement of highly successful Atlas and Delta launch vehicles, the transition to Vulcan has been slow and continues to impact the completion of Space Force mission objectives.” It has widely been known in the space community that military officials, who supported Vulcan with development contracts for the rocket and its engines that exceeded $1 billion, have been unhappy with the pace of the rocket’s development. It was originally due to launch in 2020. At the end of his written testimony, Purdy emphasized that he expected ULA to do better. As part of his job as the Service Acquisition Executive for Space (SAE), Purdy noted that he has been tasked to transform space acquisition and to become more innovative. “For these programs, the prime contractors must re-establish baselines, establish a culture of accountability, and repair trust deficit to prove to the SAE that they are adopting the acquisition principles necessary to deliver capabilities at speed, on cost and on schedule.”

SpaceX’s growth on the West Coast. SpaceX is moving ahead with expansion plans at Vandenberg Space Force Base, California, that will double its West Coast launch cadence and enable Falcon Heavy rockets to fly from California, Spaceflight Now reports. Last week, the Department of the Air Force issued its Draft Environmental Impact Statement (EIS), which considers proposed modifications from SpaceX to Space Launch Complex 6 (SLC-6) at Vandenberg. These modifications will include changes to support launches of Falcon 9 and Falcon Heavy rockets, the construction of two new landing pads for Falcon boosters adjacent to SLC-6, the demolition of unneeded structures at SLC-6, and increasing SpaceX’s permitted launch cadence from Vandenberg from 50 launches to 100.

Doubling the fun … The transformation of SLC-6 would include quite a bit of overhaul. Its most recent tenant, United Launch Alliance, previously used it for Delta IV rockets from 2006 through its final launch in September 2022. The following year, the Space Force handed over the launch pad to SpaceX, which lacked a pad at Vandenberg capable of supporting Falcon Heavy missions. The estimated launch cadence between SpaceX’s existing Falcon 9 pad at Vandenberg, known as SLC-4E, and SLC-6 would be a 70-11 split for Falcon 9 rockets in 2026, with one Falcon Heavy at SLC-6, for a total of 82 launches. That would increase to a 70-25 Falcon 9 split in 2027 and 2028, with an estimated five Falcon Heavy launches in each of those years. (submitted by EllPeaTea)
