Solar power from space? Actually, it might happen in a couple of years.

Space / /

That approach starts in low-Earth orbit rather than 36,000 km away from the surface of the Earth. Aetherflux plans to begin with a single satellite, launching into an orbit about 500 km above the planet on a SpaceX transporter mission about 12 to 15 months from now.

This initial satellite will be based on a commercially available bus from Apex, which will produce, on average, about 1 kilowatt of power. It’s a modest amount, enough electricity to power a dishwasher. This satellite will also include a high-powered infrared laser to transmit this power back to Earth. A mobile ground station, about 10 meters across, will receive the energy.

With a single satellite in low-Earth orbit, power beaming will only be available for any location on Earth for a few minutes as the spacecraft passes from horizon to horizon.

“We’ve spent a lot of time over the last year with folks within Department of Defense, and with some of the folks within DARPA,” Bhatt said. “The idea is like do a demonstration mission which kind of establishes the core functionality.”

Where is all this headed?

One of the key aspects of the test is to determine both the safety and efficiency of collecting the solar energy in space, transmitting it through the atmosphere, and then producing a usable source of power on the ground.

If the demo mission works, Aetherflux plans to develop a constellation of satellites in low-Earth orbit that could provide power continuously and at greater amounts. Initially, the company seeks to deliver power in remote locations, such as disaster relief areas, off-the-grid mining operations, or forward operating bases for the military.

“If we can make that business model work, that’s kind of the jumping-off point to being able to say, hey, could we put this on things like freight shipping?” Bhatt said. “Could we meaningfully address the ability to do freight shipping across large bodies of water with renewable energy?”

Long term, there’s the potential to provide a base load of power to augment the intermittent availability of terrestrial wind and solar energy—a key need if the world is to de-carbonize its electricity generation.

But that’s probably putting the cart before the horse. One of the biggest challenges of space-based solar power is that it has always been theoretical. It should work. But will it work? Trying out a low-cost demonstrator mission in the next couple of years is a fine way of finally putting that question to rest.

The planned May 2014 release of that module was eventually delayed until December. At the time, we noted that “a full release of the Star Citizen MMORPG [would be] expected near the end of 2016,” a date that now seems as naive as the original 2015 launch window for Squadron 42.

“We will build the game you are dreaming about”

Back in 2014, Roberts Space Industries had raised a mere $67 million from crowdfunders eager to see Roberts’ lofty vision for a new era of space simulation games. Now, that funding has climbed past a staggering $731 million from players buying pricey virtual ships in a game that still exists only as an unpolished alpha plagued with significant gameplay issues.

Roberts said in a March update that the team had “spent significant time looking at what Star Citizen 1.0 means and what it would take to get there.” For now, though, the team “is hard at work, heads down, driving toward the finish line” for Squadron 42, as highlighted by the game’s public progress tracker.

The extremely lengthy development path for Star Citizen and Squadron 42 has become something of a joke in the 12 years since it first became a crowdfunding darling. But it’s not like we weren’t warned. In 2012, Roberts Space Industries offered a public pledge that the use of crowdfunding meant the developer would “focus on quality free of the pressure to deliver by a certain financial quarter.” The team also warned that “there may be delays and there may be changes; we recognize that such things are inevitable and would be lying to you if we claimed otherwise.”

“You’ve done your part, and we will now do our utmost to live up to your expectations,” the team wrote in that now 12-year-old pledge. “We will build you the game you are dreaming about.”

SpaceX prevails over ULA, wins military launch contracts worth $733 million

falcon 9, launch, military space, Science, Space, space force, space systems command, spacex / /

These missions require medium-lift rockets, or smaller rockets capable of a high-rate launch cadence to match the capability of a larger launch vehicle. In June, the Space Force selected SpaceX, ULA, and Blue Origin, Jeff Bezos’s space company, to compete for Lane 1 launch task orders.

Military officials will add more companies to the pool of available Lane 1 launch providers as they mature their rockets. These companies may include Rocket Lab, Firefly Aerospace, Relativity Space, Stoke Space, and others.

While Blue Origin is on the Space Force’s list of available launch providers, the company’s New Glenn rocket was not eligible for the contracts announced Friday. That’s because military officials require a rocket to complete at least one successful orbital launch to become qualified for a Lane 1 task order. New Glenn’s first test flight is scheduled some time later this year.

This rule left SpaceX’s Falcon 9 and ULA’s Vulcan rockets as the only launch vehicles eligible for the task orders, setting up a head-to-head competition between the rival rocket companies. SpaceX prevailed, winning all nine Lane 1 missions up for competition this year.

Lane 2 of the Space Force’s National Security Space Launch program covers more challenging military missions, typically larger, more expensive payloads destined for higher orbits. The Space Force is expected to soon select launch providers for Lane 2 missions. These launches will require the Space Force to certify the rockets, whereas the military is comfortable accepting a little more risk for the Lane 1 missions.

SpaceX’s Falcon 9 and Falcon Heavy are currently certified for national security launches, and the Space Force is in the process of certifying ULA’s Vulcan launcher after two successful test flights. The Space Force and Blue Origin also have a certification plan for the New Glenn rocket, but it must first complete multiple successful test flights.

Updated October 19 with additional information about the launch task orders.

Finally upgrading from isc-dhcp-server to isc-kea for my homelab

Broken down that way, the migration didn’t look terribly scary—and it’s made easier by the fact that the Kea default config files come filled with descriptive comments and configuration examples to crib from. (And, again, ISC has done an outstanding job with the docs for Kea. All versions, from deprecated to bleeding-edge, have thorough and extensive online documentation if you’re curious about what a given option does or where to apply it—and, as noted above, there are also the supplied sample config files to tear apart if you want more detailed examples.)

Configuration time for DHCP

We have two Kea applications to configure, so we’ll do DHCP first and then get to the DDNS side. (Though the DHCP config file also contains a bunch of DDNS stuff, so I guess if we’re being pedantic, we’re setting both up at once.)

The first file to edit, if you installed Kea via package manager, is /etc/kea/kea-dhcp4.conf. The file should already have some reasonably sane defaults in it, and it’s worth taking a moment to look through the comments and see what those defaults are and what they mean.

Here’s a lightly sanitized version of my working kea-dhcp4.conf file: 

    "Dhcp4":       "control-socket":         "socket-type": "unix",        "socket-name": "https://arstechnica.com/tmp/kea4-ctrl-socket"      ,      "interfaces-config":         "interfaces": ["eth0"],        "dhcp-socket-type": "raw"      ,      "dhcp-ddns":         "enable-updates": true      ,      "ddns-conflict-resolution-mode": "no-check-with-dhcid",      "ddns-override-client-update": true,      "ddns-override-no-update": true,      "ddns-qualifying-suffix": "bigdinosaur.lan",      "authoritative": true,      "valid-lifetime": 86400,      "renew-timer": 43200,      "expired-leases-processing":         "reclaim-timer-wait-time": 3600,        "hold-reclaimed-time": 3600,        "max-reclaim-leases": 0,        "max-reclaim-time": 0      ,      "loggers": [      {        "name": "kea-dhcp4",        "output_options": [          {            "output": "syslog",            "pattern": "%-5p %mn",            "maxsize": 1048576,            "maxver": 8          }        ],        "severity": "INFO",        "debuglevel": 0              ],      "reservations-global": false,      "reservations-in-subnet": true,      "reservations-out-of-pool": true,      "host-reservation-identifiers": [        "hw-address"      ],      "subnet4": [        {          "id": 1,          "subnet": "10.10.10.0/24",          "pools": [            {              "pool": "10.10.10.170 - 10.10.10.254"            }          ],          "option-data": [            {              "name": "subnet-mask",              "data": "255.255.255.0"            },            {              "name": "routers",              "data": "10.10.10.1"            },            {              "name": "broadcast-address",              "data": "10.10.10.255"            },            {              "name": "domain-name-servers",              "data": "10.10.10.53"            },            {              "name": "domain-name",              "data": "bigdinosaur.lan"            }          ],          "reservations": [            {              "hostname": "host1.bigdinosaur.lan",              "hw-address": "aa:bb:cc:dd:ee:ff",              "ip-address": "10.10.10.100"            },            {              "hostname": "host2.bigdinosaur.lan",              "hw-address": "ff:ee:dd:cc:bb:aa",              "ip-address": "10.10.10.101"            }          ]              ]    }  }

The first stanzas set up the control socket on which the DHCP process listens for management API commands (we’re not going to set up the management tool, which is overkill for a homelab, but this will ensure the socket exists if you ever decide to go in that direction). They also set up the interface on which Kea listens for DHCP requests, and they tell Kea to listen for those requests in raw socket mode. You almost certainly want raw as your DHCP socket type (see here for why), but this can also be set to udp if needed.

Biden administration curtails controls on some space-related exports

Commercial space, Export controls, ITAR, national security, Science, Space / /

The US Commerce Department announced Thursday it is easing restrictions on exports of space-related technology, answering a yearslong call from space companies to reform regulations governing international trade.

This is the most significant update to space-related export regulations in a decade and opens more opportunities for US companies to sell their satellite hardware abroad.

“We are very excited about this rollout,” a senior Commerce official said during a background call with reporters. “It’s been a long time coming, and I think it’s going to be very meaningful for our national security and foreign policy interests and certainly facilitate secure trade with our partners.”

Overdue reform

One of the changes will allow US companies to export more products related to electro-optical and radar remote sensing, as well as space-based logistics, assembly, or servicing spacecraft destined for Australia, Canada, and the United Kingdom.

“They’re easing restrictions on some of the less sensitive space-related technologies and on spacecraft-related items going to our closest allies, like Australia, Canada, and the UK,” the senior Commerce official said. “These changes will offer relief to US companies and they’ll increase innovation without comprising the critical technologies that keep our nation safe.”

Another update to the Commerce Department’s regulations will remove license requirements for exports of “certain spacecraft components” to more than 40 allied nations, including NATO and European Union member states, Argentina, Australia, Canada, India, Israel, Japan, Mexico, New Zealand, Singapore, South Africa, South Korea, and Taiwan. This will also create more license exceptions to support NASA’s cooperative programs with other nations, officials said.

A third change, which hasn’t been finalized and must go through a public comment period, proposes to transfer some space-related item—spacecraft capable of in-space docking, grappling, and refueling, autonomous collision avoidance, and autonomous detection of ground vehicles and aircraft—from the highly restrictive State Department’s US Munitions List to the more flexible Commerce Control List.

MechWarrior 5: Clans is supposed to be newbie-friendly, and I put it to the test

battletech, gaming, mechwarrior, mechwarrior 5, mechwarrior 5 clans, strategy / /

There are multiple layers to a Clans battle. There is your actual movement, which can take getting used to, with your legs moving on their own trajectory while you swivel your torso. There is your squad and how they’re deployed, which takes up many of your background thought cycles. And there is your mech, its heating levels, its armor condition, its speed, and everything else you set yourself up for during customization.

Your enemies and your copilots are, well, pretty dumb. There’s good variety in what you face and what you must do, but nobody besides you on the field seems to have a great sense of how verticality works or what the most important thing on the field is at that moment. Once you accept that your squad mates are powerful dummies, you’ll learn to let go of your own mech a bit and spend more time nudging them around or jumping into their cockpits and taking over for a spell.

The nature of mech combat in these games did not, after a half-dozen missions, click with me. On some level, it’s interesting juggling various weapons, positioning yourself with limited movement, and directing teammates. I’m going slow, and it feels like a slog, but I could go faster if I had made a different choice during loadout. I’d just have to make somebody else the heavy.

But it’s also a crunchy simulation game, simulating machinery that does not actually exist. Everything that stands between you and your sense of capable combat is a choice made by the developers.

Mecha culpa

Based on my conversations with longtime MechWarrior fans and reading lots of positive reviews to figure out if there’s something wrong with me, I think MechWarrior 5: Clans is a very juicy offering for mech fans who have been hungry for something new (and especially something set in this Clans-coming-back period) for quite some time. I’m just not entranced as a newcomer, and I’m now thinking something like Armored Core VI would be more my speed if I’m looking for rocking or possibly socking robots. I also didn’t engage with multiplayer at all, so my standard dismissal of combatant AI would only half-apply there.

By all means, though, tell me and each other how this game looks or plays to you. I was not bio-engineered for MechWarrior (I mean, just look at how many contractions I use), but I can still appreciate that it looks pretty good for those who fit better into the chassis.

Amazon exec tells employees to work elsewhere if they dislike RTO policy

Amazon, AWS, Policy, return-to-office / /

Amazon workers are being reminded that they can find work elsewhere if they’re unhappy with Amazon’s return-to-office (RTO) mandate.

In September, Amazon told staff that they’ll have to RTO five days a week starting in 2025. Amazon employees are currently allowed to work remotely twice a week. A memo from CEO Andy Jassy announcing the policy change said that “it’s easier for our teammates to learn, model, practice, and strengthen our culture” when working at the office.

On Thursday, at what Reuters described as an “all-hands meeting” for Amazon Web Services (AWS), AWS CEO Matt Garman reportedly told workers:

If there are people who just don’t work well in that environment and don’t want to, that’s okay, there are other companies around.

Garman said that he didn’t “mean that in a bad way,” however, adding: “We want to be in an environment where we’re working together. When we want to really, really innovate on interesting products, I have not seen an ability for us to do that when we’re not in-person.”

Interestingly, Garman’s comments about dissatisfaction with the RTO policy coincided with him claiming that 9 out of 10 Amazon employees that he spoke to are in support of the RTO mandate, Reuters reported.

Some suspect RTO mandates are attempts to make workers quit

Amazon has faced resistance to RTO since pandemic restrictions were lifted. Like workers at other companies, some Amazon employees have publicly wondered if strict in-office policies are being enacted as attempts to reduce headcount without layoffs.

In July 2023, Amazon started requiring employees to work in their team’s central hub location (as opposed to remotely or in an office that may be closer to where they reside). Amazon reportedly told workers that if they didn’t comply or find a new job internally, they’d be considered a “voluntary resignation,” per a Slack message that Business Insider reportedly viewed. And many Amazon employees have already reported considering looking for a new job due to the impending RTO requirements.

However, employers like Amazon “can face an array of legal consequences for encouraging workers to quit via their RTO policies,” Helen D. (Heidi) Reavis, managing partner at Reavis Page Jump LLP, an employment, dispute resolution, and media law firm, told Ars Technica:

Qualcomm cancels Windows dev kit PC for “comprehensively” failing to meet standards

copilot, copilot+ PC, microsoft, snapdragon x, snapdragon x elite, Tech, Windows 11, windows 11 24h2, windows on arm / /

It’s been a big year for Windows running on Arm chips, something that Microsoft and Arm chipmakers have been trying to get off the ground for well over a decade. Qualcomm’s Snapdragon X Elite and X Plus are at the heart of dozens of Copilot+ Windows PCs, which promise unique AI features and good battery life without as many of the app and hardware compatibility problems that have plagued Windows-on-Arm in the past.

Part of the initial wave of Copilot+ PCs was a single desktop, an $899 developer kit from Qualcomm itself that would give developers and testers a slightly cheaper way to buy into the Copilot+ ecosystem. Microsoft put out a similar Arm-powered dev kit two years ago.

But Qualcomm has unceremoniously canceled the dev kit and is sending out refunds to those who ordered them. That’s according to a note received by developer and YouTuber Jeff Geerling, who had already received the Snapdragon Dev Kit and given it a middling review a couple of weeks ago.

“The launch of 30+ Snapdragon X-series powered PCs is a testament to our ability to deliver leading technology and the PC industry’s desire to move to our next-generation technology,” reads Qualcomm’s statement. “However, the Developer Kit product comprehensively has not met our usual standards of excellence and so we are reaching out to let you know that unfortunately we have made the decision to pause this product and the support of it, indefinitely.”

Qualcomm’s statement also says that “any material, if received” will not have to be returned—those lucky enough to have gotten one of the Dev Kits up until now may be able to keep it and get their money back, though the PC is no longer officially being supported by Qualcomm.

dvd, privacy, redbox, Tech / /

Thousands of Redboxes getting dumped

It’s worth noting that the amount of data expected to be stored on Redboxes is small compared to Redbox’s overall business. Since Redbox once rented out millions of DVDs weekly, the data retrieved only represents a small portion of Redbox’s overall business and, likely, of business conducted on that specific kiosk.  That might not be much comfort to those whose data is left vulnerable, though.

The problem is more alarming when considering how many Redboxes are still out in the wild with uncertain futures. High demand for Redbox removals has resulted in all sorts of people, like Turing, gaining access to kiosk hardware and/or data. For example, The Wall Street Journal reported last week about a “former Redbox employee who convinced a 7-Eleven franchisee” to give him a Redbox, a 19-year-old who persuaded a contractor hauling a kiosk away from a drugstore to give it to him instead, as well as a Redbox landing in an Illinois dumpster.

Consumer privacy concerns

Chicken Soup’s actions may violate consumer privacy regulations, including the Video Privacy Protection Act outlawing “wrongful disclosure of video tape rental or sale records.” However, Chicken Soup’s bankruptcy (most of its assets are in a holding pattern, Lowpass reported) makes customer remediation more complicated and less likely.

Mario Trujillo, staff attorney for the Electronic Frontier Foundation, told Ars that this incident “highlights the importance of security research in uncovering flaws that can leave customers unprotected.”

“While it may be hard to hold a bankrupt company accountable, uncovering the flaw is the first step,” he added.

Turing, which reverses engineers a lot of tech, said that the privacy problems she encountered with Redbox storage “isn’t terribly uncommon.”

Overall, the situation underscores the need for stricter controls around consumer data, whether it comes internally from companies or, as some would argue, through government regulation.

“This security flaw is a reminder that all companies should be obligated to minimize the amount of data they collect and retain in the first place,” Trujillo said. “We need strong data privacy laws to do that.”

It’s increasingly unlikely that humans will fly around the Moon next year

artemis II, ground systems, orion, Science, Space / /

Don’t book your tickets for the launch of NASA’s Artemis II mission next year just yet.

We have had reason to doubt the official September 2025 launch date for the mission, the first crewed flight into deep space in more than five decades, for a while now. This is principally because NASA is continuing to mull the implications of damage to the Orion spacecraft’s heat shield from the Artemis I mission nearly two years ago.

However, it turns out that there are now other problems with holding to this date as well.

No schedule margin

A new report from the US Government Accountability Office found that NASA’s Exploration Ground Systems program—this is, essentially, the office at Kennedy Space Center in Florida responsible for building ground infrastructure to support the Space Launch System rocket and Orion—is in danger of missing its schedule for Artemis II.

During this flight a crew of four astronauts, commanded by NASA’s Reid Wiseman, will launch inside Orion on a 10-day mission out to the Moon and back. The spacecraft will follow a free-return trajectory, which is important, because if there is a significant problem with Orion spacecraft’s propulsion system, the trajectory of the vehicle will still carry it back to Earth. At their closest approach, the crew will come within about 6,500 miles (10,400 km) of the surface of the far side of the Moon.

The new report, published Thursday, finds that the Exploration Ground Systems program had several months of schedule margin in its work toward a September 2025 launch date at the beginning of the year. But now, the program has allocated all of that margin to technical issues experienced during work on the rocket’s mobile launcher and pad testing.

“Earlier in 2024, the program was reserving that time for technical issues that may arise during testing of the integrated SLS and Orion vehicle or if weather interferes with planned activities, among other things,” the report states. “Officials said it is likely that issues will arise because this is the first time testing many of these systems. Given the lack of margin, if further issues arise during testing or integration, there will likely be delays to the September 2025 Artemis II launch date.”

EU considers calculating X fines by including revenue from Musk’s other firms

Digital Services Act, elon musk x, Policy / /

“After Breton resigned in September, he bequeathed his fining powers to competition and digital boss Margrethe Vestager. Decisions on the penalties and how they are calculated would ultimately lie with Vestager,” Bloomberg wrote. The European Commission would have the final say.

“The commission hasn’t yet decided whether to penalize X, and the size of any potential fine is still under discussion,” Bloomberg wrote, citing its anonymous sources. “Penalties may be avoided if X finds ways to satisfy the watchdog’s concerns.”

X says SpaceX revenue should be off-limits

Although X faces potential DSA fines, it will avoid penalties under the EU’s Digital Markets Act (DMA). The European Commission announced yesterday that X does not “qualify as a gatekeeper in relation to its online social networking service, given that the investigation revealed that X is not an important gateway for business users to reach end users.”

But documents related to the DMA probe of X raise the possibility of treating multiple Musk-led companies as a single entity called the “Musk Group” for compliance purposes. In a March 2024 letter to Musk and X Holdings Corp., “the Commission set out its preliminary views on the possible designation of Mr. Elon Musk and the companies that he controls (‘the Musk Group’) as a gatekeeper,” according to a document signed by Breton.

X has argued that it wouldn’t make sense to include Musk’s other companies in revenue calculations when issuing penalties. “X Holdings Corp. submits that the combined market value of the Musk Group does not accurately reflect X’s monetization potential in the Union or its financial capacity,” the document said. “In particular, it argues that X and SpaceX provide entirely different services to entirely different users, so that there is no gateway effect, and that the undertakings controlled by Mr. Elon Musk ‘do not form one financial front, as the DMA presumes.'”

We contacted X and SpaceX today and will update this article if they provide any comment.
