I’ll readily grant you that Houston might not be the most idyllic spot in the world. The summer heat is borderline unbearable. The humidity is super sticky. We don’t have mountains or pristine beaches—we have concrete.

But we also have a pretty amazing melting pot of culture, wonderful cuisine, lots of jobs, and upward mobility. Most of the year, I love living here. Houston is totally the opposite of, “It’s a nice place to visit, but you wouldn’t want to live there.” Houston is not a particularly nice place to visit, but you might just want to live here.

Except for the hurricanes.

Houston is the largest city in the United States to be highly vulnerable to hurricanes. At a latitude of 29.7 degrees, the city is solidly in the subtropics, and much of it is built within 25 to 50 miles of the Gulf of Mexico. Every summer, with increasing dread, we watch tropical systems develop over the Atlantic Ocean and then move into the Gulf.

For some meteorologists and armchair forecasters, tracking hurricanes is fulfilling work and a passionate hobby. For those of us who live near the water along the upper Texas coast, following the movements of these storms is gut-wrenching stuff. A few days before a potential landfall, I’ll find myself jolting awake in the middle of the night by the realization that new model data must be available. When you see a storm turning toward you, or intensifying, it’s psychologically difficult to process.

Beryl the Bad

It felt like we were watching Beryl forever. It formed into a tropical depression on June 28, became a hurricane the next day, and by June 30, it was a major hurricane storming into the Caribbean Sea. Beryl set all kinds of records for a hurricane in late June and early July. Put simply, we have never seen an Atlantic storm intensify so rapidly, or so much, this early in the hurricane season. Beryl behaved as if it were the peak of the Atlantic season, in September, rather than the beginning of July—normally a pretty sleepy time for Atlantic hurricane activity. I wrote about this for Ars Technica a week ago.

At the time, it looked as though the greater Houston area would be completely spared by Beryl, as the most reliable modeling data took the storm across the Yucatan Peninsula and into the southern Gulf of Mexico before a final landfall in northern Mexico. But over time, the forecast began to change, with the track moving steadily up the Texas coast.

I was at a dinner to celebrate the birthday of my cousin’s wife last Friday when I snuck a peek at my phone. It was about 7 pm local time. We were at a Mexican restaurant in Galveston, and I knew the latest operational run of the European model was about to come out. This was a mistake, as the model indicated a landfall about 80 miles south of Houston, which would bring the core of the storm’s strongest winds over Houston.

I had to fake joviality for the rest of the night, while feeling sick to my stomach.

Barreling inland

The truth is, Beryl could have been much worse. After weakening due to interaction with the Yucatan Peninsula on Friday, Beryl moved into the Gulf of Mexico just about when I was having that celebratory dinner on Friday evening. At that point, it was a strong tropical storm with 60 mph sustained winds. It had nearly two and a half days over open water to re-organize, and that seemed likely. Beryl had Saturday to shrug off dry air and was expected to intensify significantly on Sunday. It was due to make landfall on Monday morning.

The track for Beryl continued to look grim over the weekend—although its landfall would occur well south of Houston, Beryl’s track inland would bring its center and core of strongest winds over the most densely populated part of the city. However, we took some solace from a lack of serious intensification on Saturday and Sunday. Even at 10 pm local time on Sunday, less than six hours before Beryl’s landfall near Matagorda, it was still not a hurricane.

However, in those final hours Beryl did finally start to get organized in a serious way. We have seen this before as hurricanes start to run up on the Texas coast, where frictional effects from its outer bands aid intensification. In the last six hours Beryl intensified into a Category 1 hurricane, with 80-mph sustained winds. The eyewall of the storm closed, and Beryl was poised for rapid intensification. Then it ran aground.

Normally, as a hurricane traverses land it starts to weaken fairly quickly. But Beryl didn’t. Instead, the storm maintained much of its strength and bulldozed right into the heart of Houston with near hurricane-force sustained winds and higher gusts. I suspect what happened is that Beryl, beginning to deepen, had a ton of momentum at landfall, and it took time for interaction with land to reverse that momentum and begin slowing down its winds.

First the lights went out. Then the Internet soon followed. Except for storm chasers, hurricanes are miserable experiences. There is the torrential rainfall and rising water. But most ominous of all, at least for me, are the howling winds. When stronger gusts come through, even sturdily built houses shake. Trees whip around violently. It is such an uncontrolled, violent fury that one must endure. Losing a connection to the outside world magnifies one’s sense of helplessness.

In the end, Beryl knocked out power to about 2.5 million customers across the Houston region, including yours truly. Because broadband Internet service providers generally rely on these electricity services to deliver Internet, many customers lost connectivity. Even cell phone towers, reduced to batteries or small generators, were often only capable of delivering text and voice services.

Welcome to Edition 7.01 of the Rocket Report! We’re compiling this week’s report a day later than usual due to the Independence Day holiday. Ars is beginning its seventh year publishing this weekly roundup of rocket news, and there’s a lot of it this week despite the holiday here in the United States. Worldwide, there were 122 launches that flew into Earth orbit or beyond in the first half of 2024, up from 91 in the same period last year.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). 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.

Firefly launches its fifth Alpha flight. Firefly Aerospace placed eight CubeSats into orbit on a mission funded by NASA on the first flight of the company’s Alpha rocket since an upper stage malfunction more than half a year ago, Space News reports. The two-stage Alpha rocket lifted off from Vandenberg Space Force Base in California late Wednesday, two days after an issue with ground equipment aborted liftoff just before engine ignition. The eight CubeSats come from NASA centers and universities for a range of educational, research, and technology demonstration missions. This was the fifth flight of Firefly’s Alpha rocket, capable of placing about a metric ton of payload into low-Earth orbit.

Anomaly resolution … This was the fifth flight of an Alpha rocket since 2021 and the fourth Alpha flight to achieve orbit. But the last Alpha launch in December failed to place its Lockheed Martin payload into the proper orbit due to a problem during the relighting of its second-stage engine. On this week’s launch, Alpha deployed its NASA-sponsored payloads after a single burn of the second stage, then completed a successful restart of the engine for a plane change maneuver. Engineers traced the problem on the last Alpha flight to a software error. (submitted by Ken the Bin)

Two companies added to DoD’s launch pool. Blue Origin and Stoke Space Technologies — neither of which has yet reached orbit — have been approved by the US Space Force to compete for future launches of small payloads, Breaking Defense reports. Blue Origin and Stoke Space join a roster of launch companies eligible to compete for launch task orders the Space Force puts up for bid through the Orbital Services Program-4 (OSP-4) contract. Under this contract, Space Systems Command buys launch services for payloads 400 pounds (180 kilograms) or greater, enabling launch from 12 to 24 months of the award of a task order. The OSP-4 contract has an “emphasis on small orbital launch capabilities and launch solutions for Tactically Responsive Space mission needs,” said Lt. Col. Steve Hendershot, chief of Space Systems Command’s small launch and targets division.

An even dozen … Blue Origin aims to launch its orbital-class New Glenn rocket for the first time as soon as late September, while Stoke Space aims to fly its Nova rocket on an orbital test flight next year. The addition of these two companies means there are 12 providers eligible to bid on OSP-4 task orders. The other companies are ABL Space Systems, Aevum, Astra, Firefly Aerospace, Northrop Grumman, Relativity Space, Rocket Lab, SpaceX, United Launch Alliance, and X-Bow.

Italian startup test-fires small rocket. Italian rocket builder Sidereus Space Dynamics has completed the first integrated system test of its EOS rocket, European Spaceflight reports. This test occurred Sunday, culminating in a firing of the rocket’s kerosene/liquid oxygen MR-5 main engine for approximately 11 seconds. The EOS rocket is a novel design, utilizing a single-stage-to-orbit architecture, with the reusable booster returning to Earth from orbit for recovery under a parafoil. The rocket stands less than 14 feet (4.2 meters) tall and will be capable of delivering about 29 pounds (13 kilograms) of payload to low-Earth orbit.

A lean operation … After it completes integrated testing on the ground, the company will conduct the first low-altitude EOS test flights. Founded in 2019, Sidereus has raised 6.6 million euros ($7.1 million) to fund the development of the EOS rocket. While this is a fraction of the funding other European launch startups like Isar Aerospace, MaiaSpace, and Orbex have attracted, the Sidereus’s CEO, Mattia Barbarossa, has previously stated that the company intends to “reshape spaceflight in a fraction of the time and with limited resources.” (submitted by EllPeaTea and Ken the Bin)

NASA (labels by Ars Technica)

United Launch Alliance and Blue Origin are worried about SpaceX’s plans to launch its enormous Starship rocket from Florida.

In documents submitted to the Federal Aviation Administration last month, ULA and Blue Origin raised concerns about the impact of Starship launch operations on their own activities on Florida’s Space Coast. Blue Origin, Jeff Bezos’ space company, urged the federal government to consider capping the number of Starship launches and landings, test-firings, and other operations, and limiting SpaceX’s activities to particular times.

Elon Musk, founder and CEO of SpaceX, called Blue Origin’s filing with the FAA “an obviously disingenuous response. Not cool of them to try (for the third time) to impede SpaceX’s progress by lawfare.” We’ll get to that in a moment.

The FAA and SpaceX are preparing an environmental impact statement for launches and landings of the Super Heavy booster and Starship rocket at Launch Complex 39A at NASA’s Kennedy Space Center (KSC), while the US Space Force is working with SpaceX on a similar environmental review for Starship flights from Space Launch Complex 37 at nearby Cape Canaveral Space Force Station (CCSFS).

These reviews likely won’t be complete until late 2025, at the earliest, and only then will SpaceX be cleared to launch Starship from Florida. SpaceX also must construct launch infrastructure at both sites, which could take a couple of years. This is already underway at Launch Complex 39A.

Big rocket with a big footprint

During the environmental review process, the FAA should weigh how regular flights of the reusable Starship—as many as 120 launches per year, according to TechCrunch—will affect other launch providers operating at Cape Canaveral, ULA and Blue Origin said. SpaceX’s final proposed launch cadence from each site will be part of draft environmental assessments released for public comment as soon as the end of this year.

SpaceX plans to launch Starlink satellites, customer payloads, and missions to support NASA’s Artemis lunar landings from the launch pads in Florida. Getting a launch pad up and running in Florida is one of several schedule hurdles facing SpaceX’s program to develop a human-rated lunar lander version of Starship, alongside demonstrating orbital refueling.

Starship-Super Heavy launches and landings “are expected to have a greater environmental impact than any other launch system currently operating at KSC or CCSFS,” Blue Origin wrote. In its current configuration, Starship is the most powerful rocket in history, and SpaceX is developing a larger version standing 492 feet (150 meters) tall with nearly 15 million pounds (6,700 metric tons) of propellant. This larger variant is the one that will fly from Cape Canaveral.

“It’s a very, very large rocket, and getting bigger,” wrote Tory Bruno, ULA’s CEO, in a post on X. “That quantity of propellant requires an evacuation zone whenever fueled that includes other people’s facilities. A (weekly) launch has injurious sound levels all the way into town. The Cape isn’t meant for a monopoly.”

Enlarge / SpaceX’s Starship rocket launches from Starbase during its second test flight in Boca Chica, Texas, on November 18, 2023.

At SpaceX’s privately owned Starbase launch site in South Texas, the evacuation zone is set at 1.5 miles (2.5 kilometers) when Starship and Super Heavy are filled with methane and liquid oxygen propellants. During an actual launch, the checkpoint is farther back at more than 3 miles (5 kilometers) from the pad.

“The total launch capacity of the Cape will go down if other providers are forced to evacuate their facilities whenever a vehicle is fueled,” Bruno wrote.

We don’t yet know the radius of the keep-out zones for Starship operations in Florida, but Blue Origin wrote that the impact of Starship activities in Florida “may be even greater than at Starbase,” presumably due to the larger rocket SpaceX plans to launch from Cape Canaveral. If this is the case, neighboring launch pads would need to be evacuated during Starship operations.

Purely based on the geography of Cape Canaveral, ULA seems to have the bigger worry. Its launch pad for the Vulcan and Atlas V rocket is located less than 2.2 miles (3.5 kilometers) from Launch Complex 39A (LC-39A). SpaceX’s proposal for up to 44 launches from LC-39A “will result in significant airspace and ground closures, result in acoustic impacts felt at nearby operations, and potentially produce debris, particulates, and property damage,” ULA said.

ULA said these hazards could prevent it from fulfilling its contracts to launch critical national security satellites for the US military.

“As the largest rocket in existence, an accident would inflict serious or even catastrophic damage, while normal launch operations would have a cumulative impact on structures, launch vehicle hardware, and other critical launch support equipment,” ULA said.

Enlarge / Complex space systems like the International Space Station could be vulnerable to hackers.

If space systems such as GPS were hacked and knocked offline, much of the world would instantly be returned to the communications and navigation technologies of the 1950s. Yet space cybersecurity is largely invisible to the public at a time of heightened geopolitical tensions.

Cyberattacks on satellites have occurred since the 1980s, but the global wake-up alarm went off only a couple of years ago. An hour before Russia’s invasion of Ukraine on February 24, 2022, its government operatives hacked Viasat’s satellite-Internet services to cut off communications and create confusion in Ukraine.

I study ethics and emerging technologies and serve as an adviser to the US National Space Council. My colleagues and I at California Polytechnic State University’s Ethics + Emerging Sciences Group released a US National Science Foundation-funded report on June 17, 2024, to explain the problem of cyberattacks in space and help anticipate novel and surprising scenarios.

Space and you

Most people are unaware of the crucial role that space systems play in their daily lives, never mind military conflicts. For instance, GPS uses signals from satellites. GPS-enabled precision timing is essential in financial services where every detail—such as time of payment or withdrawal—needs to be faithfully captured and coordinated. Even making a mobile phone call relies on precise coordination of time in the network.

Besides navigation for airplanes, boats, cars, and people, GPS is also important for coordinating fleets of trucks that transport goods to stock local stores every day.

Earth-observation satellites are “eyes in the skies” with a unique vantage point to help forecast the weather, monitor environmental changes, track and respond to natural disasters, boost agricultural crop yields, manage land and water use, monitor troop movements, and much more. The loss of these and other space services could be fatal to people vulnerable to natural disasters and crop failure. They could also put global economics and security at serious risk.

Many satellites are crucial for tracking natural and human activity on Earth.

Enlarge / Many satellites are crucial for tracking natural and human activity on Earth.

Factors in play

In our report, we identified several factors that contribute to the increasing threat of space cyberattacks. For instance, it’s important to recognize that the world is at the start of a new space race.

By all accounts, space is becoming more congested and more contested. Both nation-states and private companies, which are underregulated and now own most of the satellites in orbit, are gearing up to compete for resources and research sites.

Because space is so remote and hard to access, if someone wanted to attack a space system, they would likely need to do it through a cyberattack. Space systems are particularly attractive targets because their hardware cannot be easily upgraded once launched, and this insecurity worsens over time. As complex systems, they can have long supply chains, and more links in the chain increase the chance of vulnerabilities. Major space projects are also challenged to keep up with best practices over the decade or more needed to build them.

And the stakes are unusually high in space. Orbital trash zips around at speeds of 6 to 9 miles per second and can easily destroy a spacecraft on impact. It can also end space programs worldwide given the hypothesized Kessler syndrome in which the Earth is eventually imprisoned in a cocoon of debris. These consequences weigh in favor of space cyberattacks over physical attacks because the debris problem is also likely to affect the attacker.

Moreover, given critical space infrastructure and services, such as GPS, conflicts in space can spark or add more fuel to a conflict on Earth, even those in cyberspace. For instance, Russia warned in 2022 that hacking one of its satellites would be taken as a declaration of war, which was a dramatic escalation from previous norms around warfare.

In a short video released Thursday, possibly to celebrate the US Fourth of July holiday with the biggest rocket’s red glare of them all, SpaceX provided new footage of the most recent test of its Starship launch vehicle.

This test, the fourth of the experimental rocket that NASA is counting on to land its astronauts on the Moon, and which one day may launch humans to Mars, took place on June 6. During the flight, the first stage of the rocket performed well during ascent and, after separating from the upper stage, made a controlled reentry into the Gulf of Mexico. The Starship upper stage appeared to make a nominal flight through space before making a controlled—if fiery—landing in the Indian Ocean.

The new video focuses mostly on the “Super Heavy” booster stage and its entry into the Gulf. There is new footage from a camera on top of the 71-meter-tall first stage as well as a nearby buoy at water level. The video from the buoy, in particular, shows the first stage making an upright landing into the ocean.

Starship fourth flight test.

Perhaps most intriguingly, at the end of the video, SpaceX teases an image of Starship’s large launch tower in South Texas at the Starbase facility. Prominently featured are the two “chopsticks,” large arms intended to catch the first stage booster as it slowly descends back toward its launch pad.

Then, in simulated footage, the video shows Starship’s first stage descending back toward the launch tower with the title “Flight 5.” And then it fades out.

To land, or not to land?

This supports the idea that SpaceX is working toward attempting a Starship booster catch on its next flight test, which likely will occur later this summer. Doubtless, the company still has both technical and regulatory work before this can happen.

In the days immediately following the fourth flight test, SpaceX founder Elon Musk said it was the company’s goal to make such a landing attempt on the next launch. However, during a talk last week with local residents in south Texas, Starbase General Manager Kathy Lueders said this attempt might not occur on Flight 5.

However, the new video released Thursday indicates that a catch attempt is still on the table as a possibility, and perhaps even a likelihood. Such a landing would be both stunning visually, as well as a calculated risk to SpaceX’s launch tower infrastructure, as the booster likely would be landing with a few spare tons of methane and liquid oxygen propellant in its tanks.

If SpaceX decides to press ahead with the attempt, it must still obtain a launch and reentry license from the Federal Aviation Administration, which is tasked with ensuring the safety of people and property on the ground. It seems probable that the next test flight will not occur before August.

Meanwhile, activities at the South Texas launch site may well be curtailed for a couple of days as Hurricane Beryl enters the Gulf of Mexico later on Friday and then tracks toward the Texas coast early next week. The center of Beryl is expected to pass near or north of the launch site late on Sunday night or Monday, bringing winds and surges.

However, because Beryl is not expected to be a major hurricane in terms of wind speed, these impacts should not prove catastrophic to SpaceX facilities. Heavy rainfall and inland flooding in the low-lying Starbase area is also a possibility on Monday and Tuesday before the storm pulls away.

The peril of pointing —

Did OHB really not test the satellite antennas on the ground?

SpaceX

On the day before Christmas last year, a Falcon 9 rocket launched from California and put two spy satellites into low-Earth orbit for the armed forces of Germany, which are collectively called the Bundeswehr.

Initially, the mission appeared successful. The German satellite manufacturer, OHB, declared that the two satellites were “safely in orbit.” The addition of the two SARah satellites completed a next-generation constellation of three reconnaissance satellites, the company said.

However, six months later, the two satellites have yet to become operational. According to the German publication Der Spiegel, the antennas on the satellites cannot be unfolded. Engineers with OHB have tried to resolve the issue by resetting the flight software, performing maneuvers to vibrate or shake the antennas loose, and more to no avail.

As a result, last week, German lawmakers were informed that the two new satellites will probably not go into operation as planned.

Saving SARah

The three-satellite constellation known as SARah—the SAR is a reference to the synthetic aperture radar capability of the satellites—was ordered in 2013 at a cost of $800 million. The first of the three satellites, SARah 1, launched in June 2022 on a Falcon 9 rocket. This satellite was built by Airbus in southern Germany, and it has since gone into operation without any problems.

The two smaller satellites built by OHB, flying with passive synthetic aperture radar reflectors, were intended to complement the SARah 1 satellite, which carries an active phased-array radar antenna.

“The new SARah satellites ensure that the Bundeswehr has the capability for worldwide imaging reconnaissance independent of the time of day or the weather,” the German military said at the time of the SARah 1 satellite launch. “At the same time, they provide support in the early detection and management of crises.”

This new constellation was intended to replace an aging fleet of similar, though less capable, satellites known as  SAR-Lupe. This five-satellite constellation launched nearly two decades ago.

OHB said to be at fault

According to the Der Spiegel report, the Bundeswehr says the two SARah satellites built by OHB remain the property of the German company and would only be turned over to the military once they were operational. As a result, the military says OHB will be responsible for building two replacement satellites.

Shockingly, the German publication says that its sources indicated OHB did not fully test the functionality and deployment of the satellite antennas on the ground. This could not be confirmed.

This setback comes as OHB is attempting to complete a deal to go private—the investment firm KKR is planning to acquire the German space company. OHB officials said they initiated the effort to go private late last year because public markets had “structurally undervalued” the company.

OHB has its hands in many different space businesses in Europe. The small launch firm Rocket Factory Augsburg was spun out of OHB in 2018 and is working toward its debut launch later this year or in 2025. The company is also a supplier for the larger Ariane 6 rocket and one of several private companies that is part of a coalition bidding to build a Starlink-like satellite constellation for the European Union known as IRIS2.

A small research satellite designed to study the violent processes behind the creation and destruction of chemical elements will launch on a SpaceX Falcon 9 rocket in 2027, NASA announced Tuesday.

The Compton Spectrometer and Imager (COSI) mission features a gamma-ray telescope that will scan the sky to study gamma-rays emitted by the explosions of massive stars and the end of their lives. These supernova explosions generate reactions that fuse new atomic nuclei, a process called nucleosynthesis, of heavier elements.

Using data from COSI, scientists will map where these elements are forming in the Milky Way galaxy. COSI’s observations will also yield new insights into the annihilation of positrons, the antimatter equivalent of electrons, which appear to be originating from the center of the galaxy. Another goal for COSI will be to rapidly report the location of short gamma-ray bursts, unimaginably violent explosions that flash and then fade in just a couple of seconds. These bursts are likely caused by merging neutron stars.

The COSI mission will be sensitive to so-called soft gamma rays, a relatively unexplored segment of the electromagnetic spectrum. The telescope is based on a design scientists have flown on research balloon flights.

NASA selected COSI in a competition for funding to become the next mission in the agency’s Explorers program in 2021. Earlier this year, NASA formally approved the mission to proceed into development for launch in August 2027, with an overall budget in the range of $267 million to $294 million, according to NASA budget documents.

From Florida to the equator

COSI is a relatively small spacecraft, built by Northrop Grumman and weighing less than a ton, but it will ride alone into orbit on top of a Falcon 9 rocket. That’s because COSI will operate in an unusual orbit about 340 miles (550 kilometers) over the equator, an orbit chosen to avoid interference from radiation over the South Atlantic Anomaly, the region where the inner Van Allen radiation belt comes closest to Earth’s surface.

SpaceX’s Falcon 9 will deliver COSI directly into its operational orbit after taking off from Cape Canaveral, Florida, then will fire its upper stage in a sideways maneuver to make a turn at the equator. This type of maneuver, called a plane change, takes a lot of energy, or delta-V, on par with the delta-V required to put a heavier satellite into a much higher orbit.

SpaceX

NASA awarded SpaceX a firm-fixed-price contract valued at $69 million to launch the COSI mission. This is about a 37 percent increase in the price NASA paid SpaceX in a 2019 contract for launch of the similarly sized IXPE X-ray telescope into a similar orbit as COSI. The higher price is at least partially explained by inflation.

The space agency didn’t have much of a decision to make in the COSI launch contract. The Falcon 9 is the only rocket certified by NASA that can launch a satellite with the mass of COSI into its equatorial orbit.

In the next couple of years, NASA hopes United Launch Alliance’s Vulcan rocket and Blue Origin’s New Glenn launcher will be in the mix to compete for launch contracts for missions like COSI. All of ULA’s remaining Atlas V rockets are already booked by other customers.

One of the most promising Chinese space startups, Space Pioneer, experienced a serious anomaly this weekend while testing the first stage of its Tianlong-3 rocket near the city of Gongyi.

The rocket was undergoing a static fire test of the stage, in which a vehicle is clamped to a test stand while its engines are ignited, when the booster broke free. According to a statement from the company, the rocket was not sufficiently clamped down and blasted off from the test stand “due to a structural failure.”

Video of the accidental ascent showed the rocket rising several hundred meters into the sky before it crashed explosively into a mountain 1.5 km away from the test site. (See various angles of the accident here, on the social media site X, or on Weibo.) The statement from Space Pioneer sought to downplay the incident, saying it had implemented safety measures before the test, and there were no casualties as a result of the accident. “The test site is far away from the urban area of ​​Gongyi,” the company said.

This is not entirely true, however. Located in the Henan province in eastern China, alongside the Yellow River, Gongyi has a population of about 800,000 people. The test stand is only about 5 km away from the city’s downtown and less than a kilometer from a smaller village.

Such accidents are rare in the launch industry but not unprecedented. Typically, during a static fire test, the mass of propellant on board a vehicle combined with strong clamps hold a rocket down. However, in 1952, a US Viking rocket broke loose of its moorings at White Sands Missile Range in New Mexico. It crashed 6 km downrange of the launch site without casualties.

How big of a setback?

It is unclear how big of a setback this will be for Space Pioneer, a quasi-private company founded in 2019. A little more than a year ago, Space Pioneer became the first Chinese company to reach orbit with a liquid-fueled rocket. It did so, impressively, on the first attempt of its small Tianlong-2 rocket. This was a notable achievement, but the rocket’s engines were provided by a Chinese state-operated firm, the Academy of Aerospace Liquid Propulsion Technology, rather than the private company.

For the larger Tianlong-3 rocket, Space Pioneer says it is manufacturing its own kerosene-fueled engines, known as TH-12. (They appear to have performed as expected this weekend.) Nine of these engines will power the Tianlong-3 rocket, which is intended to have a thrust of 17 tons to low-Earth orbit. The rocket’s design and the planned reuse of its first stage mimic the Falcon 9 rocket developed by SpaceX.

Space Pioneer had been prepping the vehicle for its debut launch later this summer or fall—and first-stage static-fire tests are indicative of a rocket’s final testing phase before liftoff. The company’s statement did not set a new timeline for a launch attempt but said it would complete the fault analysis “as soon as possible.”

China has the most vibrant commercial space industry in the world after the United States. Nearly a decade ago, the country’s leadership committed to sharing state-owned technology with companies that raised private funding, seeking to emulate the commercial success of SpaceX and other US companies.

Today, there are dozens of Chinese firms developing rockets, satellites, and other spaceflight products. Space Pioneer has been among the most promising, having raised more than $400 million since its inception five years ago.

NASA and SpaceX misjudged the risks from reentering space junk

Since the beginning of the year, landowners have discovered several pieces of space junk traced to missions supporting the International Space Station. On all of these occasions, engineers expected none of the disposable hardware would survive the scorching heat of reentry and make it to Earth’s surface.

These incidents highlight an urgency for more research into what happens when a spacecraft makes an uncontrolled reentry into the atmosphere, according to engineers from the Aerospace Corporation, a federally funded research center based in El Segundo, California. More stuff is getting launched into space than ever before, and the trend will continue as companies deploy more satellite constellations and field heavier rockets.

“The biggest immediate need now is just to do some more work to really understand this whole process and to be in a position to be ready to accommodate new materials, new operational approaches as they happen more quickly,” said Marlon Sorge, executive director of Aerospace’s Center for Orbital and Reentry Debris Studies. “Clearly, that’s the direction that spaceflight is going.”

Ideally, a satellite or rocket body at the end of its life could be guided to a controlled reentry into the atmosphere over a remote part of the ocean. But this is often cost-prohibitive because it would require carrying extra fuel for the de-orbit maneuvers, and in many cases, a spacecraft doesn’t have any rocket thrusters at all.

In March, a fragment from a battery pack jettisoned from the space station punched a hole in the roof of a Florida home, a rare instance of terrestrial property damage attributed to a piece of space junk. In May, a 90-pound chunk of a SpaceX Dragon spacecraft that departed the International Space Station fell on the property of a “glamping” resort in North Carolina. At the same time, a homeowner in a nearby town found a smaller piece of material that also appeared to be from the same Dragon mission.

These events followed the discovery in April of another nearly 90-pound piece of debris from a Dragon capsule on a farm in the Canadian province of Saskatchewan. NASA and SpaceX later determined the debris fell from orbit in February, and earlier this month, SpaceX employees came to the farm to retrieve the wreckage, according to CBC.

Pieces of a Dragon spacecraft also fell over Colorado last year, and a farmer in Australia found debris from a Dragon capsule on his land in 2022.

NASA orders more tests on Starliner, but says crew isn’t stranded in space

NASA and Boeing officials pushed back Friday on headlines that the commercial Starliner crew capsule is stranded at the International Space Station but said they need more time to analyze data before formally clearing the spacecraft for undocking and reentry.

Two NASA astronauts, commander Butch Wilmore and pilot Suni Williams, will spend at least a few more weeks on the space station as engineers on the ground conduct thruster tests to better understand issues with the Starliner propulsion system in orbit. Wilmore and Williams launched June 5 aboard an Atlas V rocket and docked at the station the next day, completing the first segment of Starliner’s first test flight with astronauts.

NASA managers originally planned for the Starliner spacecraft to remain docked at the space station for at least eight days, although they left open the possibility of a mission extension. The test flight is now likely to last at least a month and a half, and perhaps longer, as engineers wrestle with helium leaks and thruster glitches on Starliner’s service module.

Batteries on this Starliner spacecraft were initially only certified for a 45-day mission duration, but NASA officials said they are looking at extending the limit after confirming the batteries are functioning well.

“We have the luxury of time,” said Ken Bowersox, associate administrator for NASA’s space operations mission directorate. “We’re still in the middle of a test mission. We’re still pressing forward.”

Previously, NASA and Boeing officials delayed Starliner’s reentry and landing from mid-June, then from June 26, and now they have bypassed a potential landing opportunity in early July. Last week, NASA said in a statement that the agency’s top leadership will meet to formally review the readiness of Starliner for reentry, something that wasn’t part of the original plan.

“We’re not stuck on ISS”

Steve Stich, manager of NASA’s commercial crew program, said Friday that he wanted to clear up “misunderstandings” that led to headlines claiming the Starliner spacecraft was stuck or stranded at the space station.

“I want to make it very clear that Butch and Suni are not stranded in space,” Stich said. “Our plan is to continue to return them on Starliner and return them home at the right time. We have a little bit more work to do to get there for the final return, but they’re safe on (the) space station.”

With Starliner docked, the space station currently hosts three different crew spacecraft, including SpaceX’s Crew Dragon and Russia’s Soyuz. There are no serious plans under consideration to bring Wilmore and Williams home on a different spacecraft.

“Obviously, we have the luxury of having multiple vehicles, and we work contingency plans for lots of different cases, but right now, we’re really focused on returning Butch and Suni on Starliner,” Stich said.

“We’re not stuck on the ISS,” said Mark Nappi, Boeing’s vice president in charge of the Starliner program. “It’s pretty painful to read the things that are out there. We’ve gotten a really good test flight that’s been accomplished so far, and it’s being viewed rather negatively.”

Stich said NASA officials should have “more frequent interaction” with reporters to fill in gaps of information on the Starliner test flight. NASA’s written updates are not always timely, and often lack details and context.

NASA officials have cleared the Starliner spacecraft for an emergency return to Earth if astronauts need to evacuate the space station for safety or medical reasons. But NASA hasn’t yet approved Starliner for reentry and landing under “nominal” conditions.

“When it is a contingency situation, we’re ready to put the crew on the spacecraft and bring them home as a lifeboat,” Bowersox said. “For the nominal entry, we want to look at the data more before we make the final call to put the crew aboard the vehicle, and it’s a serious enough call that we’ll bring the senior management team together (for approval).”

Mere days before its debut, the Ariane 6 rocket loses a key customer to SpaceX

Zut Alors! —

“I am impatiently waiting to understand what reasons could have led Eumetsat to such a decision.”

–

The flight hardware core stage for Europe’s new rocket, Ariane 6, is moved onto the launch pad for the first time. A launch is due to occur on July 9, 2024.

ESA-M. Pédoussaut

In a shocking announcement this week, the European intergovernmental organization responsible for launching and operating the continent’s weather satellites has pulled its next mission off a future launch of Europe’s new Ariane 6 rocket. Instead, the valuable MTG-S1 satellite will now reach geostationary orbit on SpaceX’s Falcon 9 rocket in 2025.

“This decision was driven by exceptional circumstances” said Phil Evans, director general of the organization Eumetsat. “It does not compromise our standard policy of supporting European partners, and we look forward to a successful SpaceX launch for this masterpiece of European technology.”

The decision, taken at a council meeting of Eumetsat’s 30 member nations on Wednesday and Thursday, comes less than two weeks before the debut of the Ariane 6 rocket, scheduled for July 9.

Stabbed in the back

Outwardly, at least, this decision reflects a lack of confidence in the reliability of the Ariane 6 rocket, the ability of European companies ArianeGroup and Arianespace to produce future versions of the Ariane 6, or both. It comes not just on the eve of the long-awaited debut of the Ariane 6, but also at a time when European officials are trying to close ranks and ensure that satellites built in Europe get launched on European rockets.

The retirement of the Ariane 5 rocket last July, and years of delays in the readiness for the Ariane 6 rocket, have led to a painful period in which European officials have had to come hat-in-hand to their longtime competitor and nemesis in the rocket industry, SpaceX, for launch services. As a result some of Europe’s most valuable missions, including the Euclid space telescope and several Galileo satellites, have already launched on the Falcon 9.

This has been embarrassing enough for European launch officials, who effectively created the concept of “commercial” space launch with the first Ariane rockets decades ago. For a long time, they, alongside Russia, were the kings of launching other people’s satellites. But now, on the eve of restoring European access to space, Eumetsat has effectively stabbed this industry in the back.

That is not too strong of language, either. In its release, Eumetsat described its new Meteosat Third Generation-Sounder 1 satellite as a “unique masterpiece of European technology.” The organization added, “This first European sounding satellite in a geostationary orbit will bring a revolution for weather forecasting and climate monitoring in Europe and Africa, and make it possible, for the first time, to observe the full lifecycle of a convective storm from space.” Critically, Eutmetsat was not willing to entrust this spacecraft to Europe’s new flagship rocket.

Philippe Baptiste, the chairman and chief executive of the French space agency CNES, certainly felt the sting, calling the decision a “brutal change” and saying it was a “disappointing day” for European space efforts.

“I am impatiently waiting to understand what reasons could have led Eumetsat to such a decision, at a time where all major European space countries as well as the European Commission are calling for launching European satellites on European launchers!” Baptiste wrote on LinkedIn. “Not mentioning the fact that we are 10 days away from the maiden flight of Ariane 6. How far will we, Europeans, go in our naivety?”

Why did they do this?

It is difficult to fully understand the motivations of Eumetsat in this decision. Most probably, there were some timing and reliability concerns. The MTG-S1 satellite was due to launch on the third flight of the Ariane 6 rocket, a mission nominally scheduled for early 2025. On this timeline the satellite very likely would have gotten to space more quickly than it otherwise would now on a Falcon 9.

However, because this 4-ton satellite is going to geostationary orbit, it would have been the first mission to require the use of a more powerful version of the Ariane 6 rocket. Instead of using two solid-rocket boosters, this “64” version of the rocket uses four solid-rocket boosters. It seems likely that Eumetsat officials had concerns that the timeline for this launch would drag out and perhaps some mission assurance concerns about being the first launch of an Ariane 64 rocket.

Whatever their reasons, the European satellite officials have thrown a massive turd into the punchbowl at festivities for the debut of the Ariane 6 rocket.

Welcome to Edition 6.50 of the Rocket Report! SpaceX launched its 10th Falcon Heavy rocket this week with the GOES-U weather satellite for NOAA, and this one was a beauty. The late afternoon timing of the launch and atmospheric conditions made for great photography. Falcon Heavy has become a trusted rocket for the US government, and its next flight in October will deploy NASA’s Europa Clipper spacecraft on the way to explore one of Jupiter’s enigmatic icy moons.

Sir Peter Beck dishes on launch business. Ars spoke with the recently knighted Peter Beck, founder and CEO of Rocket Lab, on where his scrappy company fits in a global launch marketplace dominated by SpaceX. Rocket Lab racked up the third-most number of orbital launches by any US launch company (it’s headquartered in California but primarily assembles and launches rockets in New Zealand). SpaceX’s rideshare launch business with the Falcon 9 rocket is putting immense pressure on small launch companies like Rocket Lab. However, Beck argues his Electron rocket is a bespoke solution for customers desiring to put their satellite in a specific place at a specific time, a luxury they can’t count on with a SpaceX rideshare.

Ruthlessly efficient … A word that Beck returned to throughout his interview with Ars was “ruthless.” He said Rocket Lab’s success is a result of the company being “ruthlessly efficient and not making mistakes.” At one time, Rocket Lab was up against Virgin Orbit in the small launch business, and Virgin Orbit had access to capital through billionaire Richard Branson. Now, SpaceX is the 800-pound gorilla in the market. “We have a saying here at Rocket Lab that we have no money, so we have to think. We’ve never been in a position to outspend our competitors. We just have to out-think them. We have to be lean and mean.”

Firefly reveals plans for new launch sites. Firefly Aerospace plans to use the state of Virginia-owned launch pad at NASA’s Wallops Flight Facility for East Coast launches of its Alpha small-satellite rocket, Aviation Week reports. The company plans to use Pad 0A for US military and other missions, particularly those requiring tight turnaround between procurement and launch. This is the same launch pad previously used by Northrop Grumman’s Antares rocket, and it’s the soon-to-be home of the Medium Launch Vehicle (MLV) jointly developed by Northrop and Firefly. The launch pad will be configured for Alpha launches beginning in 2025, according to Firefly, which previously planned to develop an Alpha launch pad at Cape Canaveral Space Force Station in Florida. Now, Alpha and MLV rockets will fly from the same site on the East Coast, while Alpha will continue launching from the West Coast at Vandenberg Space Force Base, California.

Hello, Sweden… A few days after the announcement for launches from Virginia, Firefly unveiled a collaborative agreement with Swedish Space Corporation to launch Alpha rockets from the Esrange Space Center in Sweden as soon as 2026. Esrange has been the departure point for numerous suborbital and sounding rocket for nearly 50 years, but the spaceport is being upgraded for orbital satellite launches. A South Korean startup named Perigee Aerospace announced in May it signed an agreement to be the first user of Esrange’s orbital launch capability. Firefly is the second company to make plans to launch satellites from the remote site in northern Sweden. (submitted by Ken the Bin and brianrhurley)

China hops closer to reusable rockets. The Shanghai Academy of Spaceflight Technology (SAST), part of China’s apparatus of state-owned aerospace companies, has conducted the country’s highest altitude launch and landing test so far as several teams chase reusable rocket capabilities, Space News reports. A 3.8-meter-diameter (9.2-foot) test article powered by three methane liquid-oxygen engines lifted off from the Gobi Desert on June 23 and soared to an altitude of about 12 kilometers (7.5 miles) before setting down successfully for a vertical propulsive touchdown on landing legs at a nearby landing area. SAST will follow up with a 70-kilometer (43.5-mile) suborbital test using grid fins for better control. A first orbital flight of the new reusable rocket is planned for 2025.

Lots of players … If you don’t exclusively follow China’s launch sector, you should be forgiven for being unable to list all the companies working on new reusable rockets. Late last year, a Chinese startup named iSpace flew a hopper rocket testbed to an altitude of several hundred meters as part of a development program for the company’s upcoming partially reusable Hyperbola 2 rocket. A company named Space Pioneer plans to launch its medium-class Tianlong 3 rocket for the first time later this year. Tianlong 3 looks remarkably like SpaceX’s Falcon 9, and its first stage will eventually be made reusable. China recently test-fired engines for the government’s new Long March 10, a partially reusable rocket planned to become China’s next-generation crew launch vehicle. These are just a few of the reusable rocket programs in China. (submitted by Ken the Bin)

Spanish launch startup invests in Kourou. PLD Space says it is ready to start construction at a disused launch complex at the Guiana Space Center in Kourou, French Guiana. The Spanish launch startup announced this week a 10 million euro ($10.7 million) investment in the launch complex for its Miura 5 rocket, with preparations of the site set to begin “after the summer.” The launch pad was previously used by the French Diamant rocket in the 1970s and is located several miles away from the launch pads used by the European Ariane 6 and Vega rockets. PLD Space is on track to become the first fully commercial company to launch from the spaceport in South America.

Free access to space … Also this week, PLD Space announced a new program to offer space aboard the first two flights of its Miura 5 rocket for free, European Spaceflight reports. The two-stage Miura 5 rocket will be capable of delivering about a half-ton of payload mass into a Sun-synchronous orbit. PLD Space will offer free launch services aboard the first two Miura 5 flights, which are expected to take place in late 2025 and early 2026. The application process will close on July 30, and winning proposals will be announced on November 30. (submitted by Ken the Bin and EllPeaTea)
