The Air Force today released its environmental impact statement for SpaceX’s proposed Starship/Superheavy launch site at Cape Canaveral, generally approving an launch rate of 76 launches per year, noting that this would cause “no significant impact” on the environment while providing “beneficial impact” on the local economy.

You can read the impact statement here [pdf]. It lists 69 areas where these new operations could impact something, and found in almost all no significant impact. The beneficial impact was found in the areas where the operations would boost the local economy.

The single area where these additional launches might have an impact is the issue of noise, noting that “community annoyance may increase” due to the launches. Considering the wealth that the local community will gain from jobs, industry, and tourism due to those launches, I suspect the only whining about this noise will come from fake environmental groups opposed to anyone doing anything.

None of this is any surprise. Launches have been occurring at Cape Canaveral and the Kennedy Space Center for more than three quarters of a century, and the only significant impact to the ecology has been beneficial, reserving large areas from development where wildlife has prospered. If anything, the obviousness of this proves the utter waste of money we now spend on such reports.

The statement notes that it still will require FAA input on coordinating the closure of air space during launches, but it also appears to consider this part of normal routine actions, not a requirement the FAA can use to block operations or approval.

The number of proposed launches however is quite impressive. SpaceX’s plan would close to match the annual number of global launches by everyone for most of the space era. Nor is it impossible considering the design of the rocket and the plans the company has for getting to Mars. The site plan includes two launch mounts for Starship/Superheavy (as shown in the map above). This is in addition to the two Starship/Superheavy launch facilities the company wants to build at Kennedy.

The statement is now open to public comment through July 28, 2025. The Air Force also plans three public meetings in the Cape Canaveral area on July 8, 9, and 10. It will also make a fourth virtual public meeting available from July 15 to July 28.

Ispace confirms that its Resilience lunar lander has failed, apparently crashing on the Moon

According to an update issued several hours after the planned landing, the Japanese lunar lander startup confirmed that its Resilience lunar lander apparently crashed in its attempt to soft land on the Moon.

Ispace engineers at the HAKUTO-R Mission Control Center in Nihonbashi, Tokyo, transmitted commands to execute the landing sequence at 3:13 a.m. on June 6, 2025. The RESILIENCE lander then began the descent phase. The lander descended from an altitude of approximately 100 km to approximately 20 km, and then successfully fired its main engine as planned to begin deceleration. While the lander’s attitude was confirmed to be nearly vertical, telemetry was lost thereafter, and no data indicating a successful landing was received, even after the scheduled landing time had passed.

Based on the currently available data, the Mission Control Center has been able to confirm the following: The laser rangefinder used to measure the distance to the lunar surface experienced delays in obtaining valid measurement values. As a result, the lander was unable to decelerate sufficiently to reach the required speed for the planned lunar landing. Based on these circumstances, it is currently assumed that the lander likely performed a hard landing on the lunar surface.

After communication with the lander was lost, a command was sent to reboot the lander, but communication was unable to be re-established.

This explanation fits with the very high velocity numbers seen as the spacecraft approached the surface, much higher than intended.

Ispace has now attempted to land on the Moon twice, with both landers crashing upon approach. In this sense its record is not quite as good as the American startup Intuitive Machines, which had two landers touch down but immediately tip over, causing both to fail.

Ispace presently has three contracts to build landers with NASA, JAXA (Japan’s space agency), and the European Space Agency. The American lander is being built in partnership with the company Draper. Whether this second failure today will impact any of those contracts is uncertain at this time.

China launches another set of satellites for one of its giant internet constellations

China earlier today successfully launched the sixth set of satellites for the Thousand Sails internet constellation, its Long March 6A rocket lifting off from its Taiyuan spaceport in northern China.

Very little information appears available about this specific payload. No word also was released about where the rocket’s lower stages and four strap-on boosters crashed inside China.

SpaceX still leads the rest of the world in successful launches, 69 to 53.

Landing of Ispace’s Resilience lander uncertain

Resilence landing

The landing of Ispace’s Resilience lander on the Moon at present appears uncertain, and could be a failure. Though the announcers of the live stream had warned beforehand that it might take awhile after the planned touchdown time to confirm a successful landing, the circumstances just before landing did not appear to go as expected.

At T-1:45 minutes, with the spacecraft at an altitude of 32 feet and still moving at a speed of 116 miles per minute, all telemetry disappeared from the broadcast. Mission controllers did then indicate the spacecraft was “pitching up”, which means it was re-orienting itself for landing. At that point however no further updates were provided. Moments later we could see the engineer in mission control in the lower left of the screen capture to the right, obviously disturbed by something.

In ending the live stream a few minutes later, with no further information, the announcers added that a full report will be made during a press conference later today.

Watch the landing attempt of Ispace’s Resilience lunar lander

I have embedded the live stream below of the landing of the Japanese startup Ispace’s Resilience lunar lander, presently scheduled to occur at 3:17 pm (Eastern) today (June 6, 2025 in Japan).

The live stream goes live at about 2:00 pm (Eastern).

Resilience will attempt to land on the near side of the Moon at 60.5 degrees north latitude and 4.6 degrees west longitude, in the region dubbed Mare Frigoris (Latin for “the Sea of Cold”), as shown on the map to the right. That map also shows a number of other landings on this quadrant of the Moon, including Ispace’s previous failed attempt with its first lander, Hakuto-R1, in Atlas Crater in 2023.

For Ispace, today’s landing is critical for its future. It has contracts for future three landers with NASA, with Japan’s space agency JAXA, and with the European Space Agency, but a failure today could impact whether those contracts proceed to completion.

SpaceX launches more Starlink satellites

SpaceX this afternoon successfully launched another 27 Starlink satellites, its Falcon 9 lifting off from Vandenberg Space Force Base in California.

The first stage completed its 26th flight, landing on a drone ship in the Pacific. Also, as noted by regular reader Richard M, this was also the 500th orbital launch of a Falcon rocket, including the Falcon 1, the Falcon 9, and the Falcon Heavy. And the company has done this in only a bit over fifteen years. Quite amazing.

Orbital tug startup Impulse raises $300 million in private investment capital

Following several large contract announcements in recent weeks, the orbital tug startup Impulse has now raised an additional $300 million in private investment capital, in addition to the $150 million it raised last year.

Impulse plans to use the funding for several initiatives. One is to scale up production of its Mira and Helios vehicles to better meet demand for them. The company says it has more than 30 signed contracts for those vehicles, a backlog worth nearly $200 million. Romo said the company is seeing increasing demand for Mira, the smaller of the two vehicles, for defense applications.

The company was founded by Tom Mueller, who was one of the principal engineers during SpaceX’s development of the Falcon 9. Mira is the smaller of the two tugs, and has flown one demo mission. The larger Helios tug has not yet flown, but the company recently won a contract with the satellite company SES to use it.

The company has also said it is developing its own rocket, but I suspect its first launch that will come later.

Voyager announces first public stock offering, valued at $1.6 billion

Starlab design in 2025

The space station startup Voyager Technologies yesterday announced its first public stock offering, with the hope of raising almost $400 million in investment capital.

Underwriters have a 30-day option to purchase up to 1.65 million additional Class A shares, on top of the 11 million initially offered, which are expected to be priced between $26 and $29 each. If fully subscribed at the top end of the range, the IPO could raise as much as $367 million in gross proceeds.

Voyager plans to build the Starlab space station, launched as a single large module by SpaceX’s Starship/Superheavy rocket, but so far has cut no metal, focusing its work entirely on designs. It has also signed deals with several foreign companies in Europe and Japan as well as the European Space Agency, positioning itself as providing the international community a station to replace ISS when it is gone.

At the moment however I rank Starlab fourth among the four commercial space stations under development, mostly because it has built nothing. Hopefully the funds raised by this stock offering will allow it to start some construction work.

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for an estimated 30 days total. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS, with a fourth scheduled for early June, carrying passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreement with the European Space Agency. It recently had its station design approved by NASA, but it has built nothing. This might change once it obtains several hundred million dollars from its initial public offering of stock.

Proposed commercial spaceport in Nova Scotia gets launch customer

The proposed commercial spaceport in Nova Scotia, operated by Maritime Launch Services, announced this week that it has signed a contract with a Netherlands rocket startup, T-Minus, whereby the latter will do two suborbital launches of its new Barracuda sounding rocket.

On 3 June 2023, Maritime Launch Services, a Canadian commercial launch facility operator, announced that it had signed an agreement with T-Minus Engineering for the launch of two Barracuda rockets. According to the press release, the two launches will carry various scientific and educational payloads for several customers, whose names were not disclosed. The launches are expected to take place from Spaceport Nova Scotia in October 2025.

The viability of both the rocket startup and spaceport are open to question. T-Minus was founded in 2011, and has apparently done little in that time period. It claims it is flown this rocket many times, but if so there is little solid information confirming this fact. Most of its business appears to have been flying very small sounding rockets for European defense agencies.

Maritime Launch Services first proposed this spaceport in 2017, but has seen only one student suborbital launch in that time. Its original plan was to offer both the launchpad and rocket to satellite manufacturers. The rocket however was Ukrainian-built, and when Russia invaded the Ukraine that rocket was no longer available. Furthermore, red tape in Canada stalled launch approvals for years.

Recently the spaceport has been marketing itself to multiple rocket companies, announced a number of deals with unnamed startups or named startups that haven’t flown anything yet. It has also signed a partnership deal with the space station company (Voyager), apparently to bring some real technical expertise to the operation.

Nothing real at this spaceport however has actually yet occurred. Whether this new deal is real will have to wait for something to happen.

Two launches today by American companies

The beat goes on: Two different American rocket companies today completed successful launches.

First, Rocket Lab placed a BlackSky high resolution Earth imaging satellite into orbit, its Electron rocket lifting off from one of its two launchpads in New Zealand. This was the second of four launches that BlackSky has purchased from Rocket Lab.

Next, SpaceX continued its unrelenting launch pace, placing 23 Starlink satellites into orbit (with 13 having phone-to-satellite capabilities), its Falcon 9 rocket lifting off from Cape Canaveral. The first stage completed its 21st flight, landing on a drone ship in the Atlantic.

Texas legislature gives Starbase power to close Boca Chica beaches

The Texas legislature this week approved language that now gives the new government of Starbase the power to close the road to Boca Chica’s beaches, taking that power from the local county.

House Bill 5246 revises the power and duties of the Texas Space Commission and the Texas Aerospace Research and Space Economy Consortium. A conference committee report of the bill added a section that allows the Space Commission to coordinate with a city to temporarily close a highway or venue for public safety purposes.

In South Texas, that will give the Starbase city commissioners the authority to approve those closures which would affect State Highway 4, a road that runs through Starbase and leads to the beach, as well as the beach itself.

As is usual for the particular news outlet at the link, it magnifies the opposition to SpaceX, amplifying the size of the several tiny leftist activist organizations that have been trying to shut down SpaceX at Boca Chica since the day Elon Musk announced he was now voting Republican. In reality, that opposition is nil. The region is thrilled by the wealth and jobs that SpaceX is bringing to the area, and is willing do help it grow in all ways. This action by the state legislature only reflects that support.

I must also note that the opposition in the legislature came entirely from the Democratic Party, once again taking the 20% side of an 80-20 issue.

Trump’s NASA budget cuts and rejection of Jared Isaacman for NASA administrator signal a very bright future for American space

To most Americans interested in space exploration, my headline above must seem extremely counter-intuitive. For decades Americans have seen NASA as our space program, with any cuts at NASA seen as hindering that effort. Similarly, Isaacman, a businessman and private astronaut who has personally paid for two flights in space, had initially been nominated by Trump to become NASA administrator expressly because of that commercial space background. For Trump to reject such a person now seems at the surface incredibly damaging to NASA’s recent effort to work with the private sector.

All of that seems true, but it really is not. Both of these actions by Trump are simply what may be the last acts in the major change that has been engulfing the American space industry now for the past decade.

Jared Isaacman

Jared Isaacman during his spacewalk
Jared Isaacman during his spacewalk in September 2024

First, let’s consider Isaacman. Before Trump had nominated him for NASA administrator, he had been a free American doing exactly what he wanted to do. As a very wealthy and successful businessman, he had decided to use that wealth to not only fly in space — fulfilling a personal dream — but to also use those flights to raise money for St. Jude’s Children’s hospital, whose work he considered priceless and wanted supported. He ended up flying two space missions, becoming the first private citizen to do a spacewalk, while also raising more than $200 million for St. Jude’s.

Isaacman’s second flight was also the first in what he hoped would be his own long term manned space program, which he dubbed Polaris. The first mission did this spacewalk from a SpaceX capsule. The second would hopefully do a repair mission to Hubble, or if rejected by NASA some other work in orbit. And the third would fly in SpaceX’s Starship around the Moon.

As this program was funded entirely by Isaacman and used no government funds, it was generally free from criticism. If anything, Americans hailed it as ambitious and courageous. He was following his own American dream, and doing it on his own dime.

This history however made him appear on the surface to be a perfect choice for NASA administrator under Trump, especially in a time where America’s space effort is shifting more and more to the private sector.

Everything changed however once Trump nominated him. He had to suspend his private Polaris program. He had to kow-tow to politicians, telling them what they wanted to hear. And he was no longer his own boss.

Proposed Australian spaceport changes name

A proposed Australian spaceport company that was previously called Equatorial Launch Australia and was forced to shift its location because of red tape has apparently changed its name to Space Centre Australia and named its proposed spaceport the Atakani Space Centre.

It is also possible there was a major shake-up in management, but this is unclear from available sources.

The map to the right shows the location where Atakani is planned, on Cape York in Queensland. Previously this company hoped to build the spaceport to the west in the Northern Territory, but local bureaucracy made that impossible.

Right now the company hopes to open for launches by 2029.

Judge rules that SpaceX’s lawsuit against the California Coastal Commission can go forward

A federal judge yesterday ruled that SpaceX’s lawsuit against the California Coastal Commission for its actions attempting to block Falcon 9 launches at Vandenberg because a majority of the commissioners don’t like Elon Musk’s politics can now go forward.

U.S. District Judge Stanley Blumenfeld Jr., a Donald Trump appointee, denied in part California’s request to dismiss the case at a hearing Friday in Los Angeles federal court. In a tentative decision, which wasn’t made publicly available, the judge rejected the state’s argument that four of SpaceX’s claims for declaratory relief weren’t “ripe” because the commission hadn’t enforced a threatened requirement for SpaceX to obtain a coastal development permit for the expanded launch schedule. “The tentative doesn’t find that the evidence is compelling, but that it is sufficient at this stage,” the judge said at the hearing.

This same judge had earlier ruled in favor of the coastal commission, noting that the commission has no real power to limit SpaceX operations at the military base and thus the company could not demonstrate harm. SpaceX amended its complaint to emphasize the harm caused to Musk’s free speech rights, and this was sufficient for the judge to change his ruling in favor of SpaceX.

This ruling doesn’t mean SpaceX and Musk have won. It means the judge considers their case sufficient for it to the lawsuit to proceed.

SpaceX’s complaint stems from an insane October 2024 hearing before the commission, where multiple commissioners came out against a SpaceX request to increase its launches at Vandenberg not because it might harm the environment but because Elon Musk now supported Donald Trump.

Their actions that day were a clear abuse of power for political reasons, and a clear violation of Elon Musk’s right to free speech.

Supreme Court unanimously rules the federal government’s regulatory overuse of environmental impact statements is wrong

In a ruling that will have wide-ranging impacts across multiple industries, including rocketry, the Supreme Court yesterday ruled 8-0 that the mission creep expansion of federal government’s regulatory use of environmental impact statements (EIS) to hinder all new construction projects is incorrect and must stop.

The case involved a planned railroad in Utah, that had gotten all its permits for construction, including approval of its environmental impact statement, but was then stymied by lawsuits by political activist groups that claimed the impact statement, issued under the National Environmental Policy Act (NEPA), had not considered the impact of the industries the railroads would serve, including impacts far from the railroad’s location itself.

This is a perfect example of the broad expansion of NEPA that has been imposed in the last two decades by federal bureaucracy working hand-in-glove with these leftist political groups.

The Supreme Court, including all of the Democratic Party appointees, said enough!

In its majority opinion, authored by Justice Brett Kavanaugh, the Court clarified that under NEPA the STB “did not need to evaluate potential environmental impacts of the separate upstream and downstream projects.” The Court concluded that the “proper judicial approach for NEPA cases is straightforward: Courts should review an agency’s EIS to check that it addresses the environmental effects of the project at hand. The EIS need not address the effects of separate projects.”

This statement “is particularly significant for infrastructure projects, such as pipelines or transmission lines, and should help reduce NEPA’s burdens (at least at the margins),” wrote Jonathan Adler, a law professor at the Case Western Reserve University School of Law, in The Volokh Conspiracy. “The opinion will also likely hamper any future efforts, perhaps by Democratic administrations, to expand or restore more fulsome (and burdensome) NEPA requirements.”

The article notes (and confirms) what I have been writing now for the past five years in connection with the FAA’s demand that rocket companies require new impact statements every time they revise their operations, even when those changes are relatively minor.

This point could reduce one of the largest delays caused by NEPA: litigation. Since its passage in 1969, NEPA has been weaponized by environmental groups to stunt disfavored projects—which has disproportionately impacted clean energy projects. On average, these challenges delay a permitted project’s start time by 4.2 years, according to The Breakthrough Institute.

The increased threat of litigation has forced federal agencies to better cover their bases, leading to longer and more expensive environmental reviews. With courts deferring more to agency decisions, litigation could be settled more quickly.

This ruling is an excellent move in the right direction, but no one should assume it will be followed honestly by the next Democrat who sits in the White House. Just as Biden expanded red tape by simple forcing the FAA to slow-walk its launch licensing process, future presidents could do the same.

Nor should be expect the lawsuits by these luddite leftists to cease. They will find other legal challenges and will push those instead.

The real solution is to reduce the bureaucracy’s size entirely, so there won’t be paper-pushers for these petty dictators to utilize for their authoritarian purposes. Eliminating or simplifying these environmental regulations would help as well, giving the activists fewer handles on which to hang their lawsuits.

SES cleared by the United Kingdom to buy Intelsat

The long-established Luxembour satellite company SES has now gotten regulatory approval from the United Kingdom to buy another long-established satellite company, Intelsat, with the purchase price €2.8 billion.

SES’s €2.8 billion acquisition of Intelsat was cleared by the UK’s competition regulator, in a move that will create a satellite giant to better compete with Elon Musk’s Starlink. The Competition and Markets Authority decided on the basis of “the information currently available to it,” to not subject the deal to an in-depth probe, it said in a statement on Friday.

The deal still needs to be approved by the European Union, which has set June 10th as the deadline for a decision.

This merger is because these older satellite companies are presently losing in competition with the many new low-orbit satellite constellations by new companies, led mostly by Starlink. By merging they hope to compete better.

SpaceX launches GPS satellite for military

SpaceX this morning successfully placed a military GPS satellite into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its fourth flight, landing on a drone ship in the Atlantic. As of posting the satellite has not yet been deployed.

This was the second military GPS launch that the Space Force has taken from ULA and its Vulcan rocket and given to SpaceX instead. Even though Vulcan was certified in late March by the military for these kinds of military launches, delays in getting Vulcan operational forced the Space Force to find another more reliable launch provider. Even now, two months after that certification, ULA has still not announced a launch schedule for this rocket. The company in December 2024 had predicted it would launch 20 times in 2025, with 16 of those launches being by Vulcan. The year is almost half over now and ULA has only launched once, using an Atlas 5 rocket.

SpaceX: We are targeting 170 launches in 2025

According to a statement by a SpaceX official during a telephone press conference on May 28, 2025, the company is now hoping to complete 170 total launches in 2025.

“We’re targeting 170 launches by the end of the year,” Anne Mason, director of national security space launch at SpaceX, said during a call with reporters on Wednesday (May 28).

…”I always find it amazing that this cadence has become somewhat normal,” Mason added during Wednesday’s call, which served to preview SpaceX’s planned Friday (May 30) launch of the GPS III SV08 satellite for the U.S. Space Force. “But if we look back just five years ago, in 2020 when we launched roughly 25 times, which is still a healthy rate at twice a month, and now launching on average every two to three days — I think this demonstrates how Falcon’s reusability and reliability, plus the hard work and dedication of the SpaceX team, has been critical to supporting assured access to space,” she said.

Last year SpaceX set a record of 137 successful orbital launches, a number that also exceeded what the entire world had accomplished yearly for most of the space age since Sputnik in 1957. This new goal however appears to be a reduction from its earlier hopes. Near the start of the year SpaceX officials had predicted it would complete 180 launches.

There is also the possibility that Mason above was only referring to Falcon 9 and Falcon Heavy launches, and not counting the test flights of Starship and Superheavy.

Either way, SpaceX continues to prove that freedom and private enterprise can do far more than government, and do it faster and cheaper as well.

Northrop Grumman invests $50 million in Firefly and new rocket

Northrop Grumman and the rocket startup Firefly announced yesterday that the former has invested $50 million in the latter in order to develop a fully new rocket, dubbed Eclipse, with capabilities allowing it to compete with SpaceX for customers.

“Firefly is incredibly grateful for Northrop Grumman’s investment that further solidifies our first-of-its-kind partnership to build the first stage of Antares 330 and jointly develop Eclipse,” said Jason Kim, CEO of Firefly Aerospace. “…With a 16 metric ton to orbit capability, Eclipse is a sweet spot for programs like NSSL Lane 1 and a natural fit to launch proliferated constellations in LEO, MEO, GEO, and TLI.”

Built upon Northrop Grumman’s Antares and Firefly’s Alpha rocket, Eclipse offers a significant leap in power, performance, production cadence, and payload capacity. The launch vehicle retains the flight-proven avionics from the Antares program with additional upgrades, including a larger 5.4 meter payload fairing. Eclipse also utilizes the same first stage Firefly is developing for Antares 330 and retains scaled-up versions of Alpha’s propulsion systems and carbon composite structures, allowing the team to rapidly build and test Eclipse with significant production efficiencies and economies of scale.

The companies say that because of its reliance on already proven launch rockets, they hope Eclipse’s first launch will take place in 2026 from Wallops Island.

As I noted yesterday, the demand for launch services — especially for heavier payloads — presently exceeds the supply, as already established rocket companies ULA and Blue Origin have so far failed to deliver as promised. Rocket Lab is developing its medium-lift Neutron expressly to grab this market. It now appears Northrop Grumman wants a share as well, and is partnering with Firefly to get it.

If all goes as planned this partnership will soon have two rockets to offer customers, the Antares 330 and Eclipse.

Chinese pseudo-company completes successful hop test of rocket

The Chinese pseudo-company Space Epoch (also called SEpoch) announced today a successfully hop test yesterday where its prototype YXZ-1 grasshopper-type test prototype completed a vertical launch to an altitude of about 1.5 miles, shut down its engines, then relit them to achieve a soft splashdown over water.

The test article used thin-walled stainless steel and had a diameter of 4.2 meters, a total height of 26.8 meters and a takeoff mass of about 57 tons, according to Space Epoch. The test lasted 125 seconds and reached around 2.5 kilometers in altitude. The test article used Longyun methane-liquid oxygen engines provided by [pseudo]-commercial firm Jiuzhou Yunjian (JZYJ).

Sepoch says the test has laid a solid foundation for the first full flight of the YXZ-1, also known as Hiker-1 in English, later this year.

Without question China’s pseudo-companies as well as its official state space divisions are aggressively pursuing reusable rockets, far more aggressively than any companies (other than SpaceX) in the west. There are at least nine Chinese pseudo-companies or government agencies testing rockets that can land vertically (Space Epoch, Landspace, Deep Blue, Shanghai Academy of Spaceflight Technology, Chinese Academy of Sciences, Space Pioneer, Ispace, Galactic Energy, Linkspace), with eight having attempted hop tests with mixed results.

In the west, only SpaceX is flying reusable rockets. Blue Origin’s New Glenn is supposed to be reusable, but it has only launched once and on that flight its first stage failed to land successfully. The company has only done hop flights with its small suborbital New Shepard spacecraft. Rocket Lab is building its reusable Neutron rocket, but it also has never done any hop tests with that rocket. Stoke Space plans a completely reusable rocket, with the second stage returning as well, and has done one short hop test of a prototype of that stage. Other rocket companies are designing or developing such rockets, but none have done any hop tests.

In general China’s rocket industry appears far ahead in this race.

China launches classified satellite

China today successfully launched a classified Earth observation satellite to do “national land surveys, environmental management and other fields,” its Long March 4B rocket lifting off from its Jiuquan spaceport in northwest China.

South Korea rocket startup launches small prototype rocket

Unastella rocket at launch
Unastella rocket at launch

A South Korea rocket startup dubbed Unastella on May 28, 2025 successfully launched a small prototype suborbital rocket from its own launch site near the country’s southern coast.

UNA EXPRESS-I is 9.45 meters long and has a total weight of 2 tons. It is a small launch vehicle that uses kerosene (jet fuel) and liquid oxygen as fuel, with a thrust of 5 tons. The vehicle successfully completed its flight to the target distance of 10 kilometers and fell into the maritime safety zone set by Goheung County, the company stated. Park Jae-hong, the CEO of Unastella, noted, “For the first launch, we lowered the altitude for safety and extended the reach.”

This is South Korea’s second rocket startup that has launched a small test prototype, the first being Innospace which launched its test rocket from Brazil in 2023 and hopes to do an orbital launch before the end of the year.

It appears that South Korea is shifting successfully to the capitalism model. Back in 2023 it was trying to develop its government-built Nuri rocket, but that development seems to have stalled. Since then its newly formed space agency has established policies encouraging private space commercialization, which has apparently resulted in these two new rocket companies.

China launches its first asteroid sample return mission

China today successfully launched Tianwen-2, its first mission attempting to return a sample from a near Earth asteroid, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

Video of the launch can be found here. The probe will take about a year to reach asteroid Kamo’oalewa, where it will fly in formation studying it for another year, during which time it will attempt to grab samples by two methods. One method is a copy of the touch-and-go technique used by OSIRIS-REx on Bennu. The second method, dubbed “anchor and attach,” is untried, and involves using four robot arms, each with their own drill.

Some data suggests Kamo’oalewa is possibly a fragment from the Moon, but that is not confirmed.

After a year studying Kamo-oalewa, Tienwen-2 will then return past the Earth where it will release its sample capsule. The spacecraft will then travel to Comet 311P/PANSTARRS, reaching it in 2034. This comet is puzzling because it has an asteroid-like orbit but exhibits activity similar to a comet.

As for the launch, there is no word where the Long March 3B’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China. It should be noted that the video I link to above was taken by an ordinary citizen watching from a hill nearby, bringing with him a group of children as well. Considering the nature of the rocket’s fuel (which can dissolve your skin if it touches you), China’s attitude is remarkably sanguine to not only drop these stages on its people, but to allow tourists to get so close to launches.

The leaders in the 2025 launch race:

65 SpaceX
31 China (with one more launch scheduled later today)
6 Rocket Lab (with one launch scheduled for today SCRUBBED)

The beat goes on! SpaceX this morning successfully placed another 27 Starlink satellites into orbit (including 13 with cell-to-satellite capabilities), its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida.

The first stage completed its nineteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

65 SpaceX
30 China (with two launches scheduled later today)
6 Rocket Lab (with one launch scheduled for today SCRUBBED)
6 Russia

SpaceX now leads the rest of the world in successful launches, 65 to 49.

SpaceX launches Starship/Superheavy on ninth test flight, but experiences issues in orbit

SpaceX today was able to successfully launch Starship and Superheavy on its ninth test flight, lifting off from SpaceX’s Starbase spaceport at Boca Chica.

The Superheavy booster completed its second flight, with one of its Raptor engines actually flying for the third time. Rather than recapture it with the launchpad chopsticks, engineers instead decided to push its re-entry capabilities to their limit. The booster operated successfully until it was to make its landing burn over the Gulf of Mexico, but when the engines ignited all telemetry was lost. Apparently that hard re-entry path was finally too much for the booster.

Starship reached orbit and functioned successfully for the first twenty minutes or so. When engineers attempted a test deployment of some dummy Starlink satellites, the payload door would not open properly. The engineers then closed the door and canceled the deployment.

Subsequently leaks inside the spacecraft with its attitude thrusters caused the attitude system to shut down and Starship started to spin in orbit. At that point the engineers cancelled the Raptor engine relight burn. The spacecraft then descended over the Indian Ocean as planned, but in an uncontrolled manner. Mission control then vented its fuel to reduce its weight and explosive condition. It essentially broke up over the ocean, with data was gathered on the thermal system until all telemetry was lost.

Though overall this was a much more successful flight than the previous two, both of which failed just before or as Starship reached orbit, the test flight once again was unable to do any of its objectives in orbit. It did no deployment test, no orbital Raptor engine burn test, and no the re-entry tests of Starship’s thermal protection system. Obviously the engineers gathered a great deal of data during the flight, but far less than hoped for.

SpaceX has a lot of Superheavy and Starship prototypes sitting in the wings. I expect it will attempt its next flight test, the tenth, relatively quickly, by July at the very latest. I also do not expect the FAA to stand in the way. It will once again accept SpaceX’s investigative conclusions instantly and issue a launch license, when SpaceX stays it is ready to launch.

As Starship reached orbit as planned, I am counting this as a successfully launch. The leaders in the 2025 launch race:

64 SpaceX
30 China
6 Rocket Lab
6 Russia

SpaceX now leads the rest of the world in successful launches, 64 to 49.

SpaceX launches 24 Starlink satellites

SpaceX today successfully placed another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force base in California.

The first stage completed its thirteenth flight, landing on a drone ship in the Pacific. At least, it appeared so, though there were problems this time with the live stream, which cut off just before touchdown.

The leaders in the 2025 launch race:

63 SpaceX
30 China
6 Rocket Lab
6 Russia

SpaceX now leads the rest of the world in successful launches, 63 to 49.

Live stream of Elon Musk’s speech to SpaceX employees today

FINAL UPDATE: It appears his talk has been called off, for the present. I suspect he wants a better idea what happened on today’s flight before speaking.

UPDATE: It appears Musk has rescheduled his speech for 6 pm (Central) tonight, after the launch of the ninth test flight of Starship/Superheavy. The embedded live stream below is for this rescheduled broadcast.

I have embedded below the Space Affairs live stream of Elon Musk’s speech that he plans to give to his SpaceX employees today at 10 am (Pacific) today. Musk has entitled it “The road to making life interplanetary.” He has already indicated that he will outline in more detail SpaceX’s program for getting Starship/Superheavy operational, including the likelihood of test flights to Mars in the near future.

Cargo Dragon splashes down and is recovered successfully

A SpaceX cargo Dragon capsule was recovered successfully earlier today after it splashed down off the coast of California.

The spacecraft carried back to Earth about 6,700 pounds of supplies and scientific experiments designed to take advantage of the space station’s microgravity environment after undocking at 12:05 p.m., May 23, from the zenith port of the space station’s Harmony module.

Some of the scientific hardware and samples Dragon will return to Earth include MISSE-20 (Multipurpose International Space Station Experiment), which exposed various materials to space, including radiation shielding and detection materials, solar sails and reflective coatings, ceramic composites for reentry spacecraft studies, and resins for potential use in heat shields. Samples were retrieved on the exterior of the station and can improve knowledge of how these materials respond to ultraviolet radiation, atomic oxygen, charged particles, thermal cycling, and other factors.

Other cargo returned included a robot hand that tested its grasping and handling capabilities in weightlessness, as well as other experiments.

The capsule itself spent three months in orbit after launching at the end of April.

SpaceX launches more Starlinks

Earlier today SpaceX successfully placed another 23 Starlink satellites into orbit (including 13 with cell-to-satellite capability), its Falcon 9 lifting off from Cape Canaveral in Florida.

The first stage completed its 24th flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

62 SpaceX
30 China
6 Rocket Lab
6 Russia

SpaceX now leads the rest of the world in successful launches, 62 to 49. The company also has another Starlink launch planned for tomorrow morning. The launch was scrubbed, rescheduled for May 27th.
