First unmanned Gaganyaan mission facing delay

9:33 am

Though this is not yet confirmed, sources inside India’s space agency ISRO are saying that the first unmanned Gaganyaan orbital test mission, presently targeting a March launch, is likely to be delayed in order to do additional safety checks, following the two consecutive launch failures of the agency’s PSLV rocket.

After the dual PSLV setbacks, there is zero appetite for risk at Isro. Every component, fitting, system, and subsystem of Gaganyaan is being re-examined in minute detail to ensure mission success.

The PSLV, traditionally regarded as Isro’s workhorse launcher, suffered rare back-to-back failures over the past two years, prompting a comprehensive review of quality assurance and mission readiness protocols across launch vehicles. While Gaganyaan is slated to fly aboard the Human-Rated Launch Vehicle Mark-3 (HLVM3), an upgraded version of the GSLV Mk-III, the recent setbacks have cast a shadow over the broader launch ecosystem.

The actual manned mission is presently scheduled for early next year, after a series of unmanned orbital test flights are completed in ’26. This schedule is significantly later than ISRO’s original schedule. When the program was first proposed in 2018, ISRO said the manned mission would happen in 2022.

SpaceX launches 29 Starlink satellites

9:04 am

SpaceX early today successfully launched another 29 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its 26th flight, landing on a drone ship in the Atlantic, within the territorial waters of the Bahamas for the second time.

The 2026 launch race:

20 SpaceX
8 China
2 Rocket Lab
2 Russia
1 ULA
1 Europe (Arianespace)

As it did in both ’24 and ’25, SpaceX in ’26 so far has more launches than the entire rest of the world combined.

NASA today completes SLS wet dress rehearsal with few problems

8:35 pm

NASA today successfully completed its SLS wet dress rehearsal countdown with few problems, fueling the rocket completely and then running the countdown down to T-33 seconds and then recycling back to T-10 minutes and running the countdown down again, this time to T-29 seconds.

During the day-long event there were only two minor issues, neither of significance. Early in the day there was “an issue with ground communications” that required mission control to shift to “backup communication methods” for about a half hour before the issue was resolved.

Then, during the first countdown to T-33 the count was paused and recycled once “due to a booster avionics system voltage anomaly.” This also appeared to be minor issue quickly resolved.

NASA will hold a press conference tomorrow at 11 am (Eastern) to discuss the results of the entire rehearsal.

NASA administrator Jared Isaacman had stated previously that he needed to see a perfect rehearsal before he would approve the launch of Artemis-2, carrying four astronauts on a ten-day mission around the Moon. While today’s rehearsal was not “perfect,” the issues were very minor. I suspect he will give the okay, with a tentative launch date of March 6, 2026 already being considered. The present launch window closes on April 6, 2026.

That mission, should it fly, still carries enormous risk. The Orion capsule will be using a life support system never tested in space before. It will also be using a heat shield that is questionable, having failed to behave as expected in the first Artemis mission in 2022.

NASA on Starliner: Too much freedom caused the failure!

2:59 pm

Starliner docked to ISS
Starliner docked to ISS in 2024.

NASA today released its final investigation report on the causes behind the Starliner thruster issues during that capsule’s only manned mission in ISS, issues that almost prevented the spacecraft from docking successfully and could have left it manned and out-of-control while still in orbit.

You can read the report here [pdf]. NASA administrator Jared Isaacman made it clear in his own statement that the Starliner incident was far more serious than originally let on.

“To undertake missions that change the world, we must be transparent about both our successes and our shortcomings. We have to own our mistakes and ensure they never happen again. Beyond technical issues, it is clear that NASA permitted overarching programmatic objectives of having two providers capable of transporting astronauts to-and-from orbit, influence engineering and operational decisions, especially during and immediately after the mission. We are correcting those mistakes. Today, we are formally declaring a Type A mishap and ensuring leadership accountability so situations like this never reoccur. We look forward to working with Boeing as both organizations implement corrective actions and return Starliner to flight only when ready.”

A Type A mishap is one in which a spacecraft could become entirely uncontrollable, leading to its loss and the death of all on board. Though Starliner was NOT lost, for a short while as it hung close to ISS that result was definitely possible. Its thrusters were not working. It couldn’t maneuver to dock, nor could it maneuver to do a proper and safe de-orbit. Fortunately, engineers were able to figure out a way to get the thursters operational again so a docking could occur, but until then, it was certainly a Type A situation.

The report outlines in great detail the background behind Starliner’s thruster issues, the management confusion between NASA and Boeing, and the overall confused management at Boeing itself, including its generally lax testing standards.

The report’s recommends that NASA impose greater control over future commercial contracts, noting that under the capitalism model that NASA has been following:

Pluto’s splotched surface

Pluto's splotched surface
For original images go here and here.

Cool image time! The panorama above was created using two photographs (found here and here) taken by New Horizons during its close fly-by of Pluto on July 14, 2015. It looks at Pluto’s western limb, well lit by the Sun, from a distance of approximately 60,000 miles.

I pulled these images from the New Horizons’ archive specifically because I don’t remember ever seeing them publicly released by the science team. More important, they show a surface far more alien than other more well-known New Horizon pictures. Are those round splotches impact craters or some alien type of volcanic caldera? Note also the vertical cracks that appear to divide this terrain near the center.

It would be a serious mistake to make any conclusions. In the emptiness of the outer solar system, the impact rates are going to be far less than in the inner solar system, so assuming impacts is dangerous. Pluto meanwhile has an alien surface of frozen nitrogen seas often filled with floating mountains of frozen water ice. For it to also produce weird volcanic eruptions of nitrogen, sublimating away like bubbling tomato sauce when it is simmering, is quite possible.

Chinese pseudo-company Landspace targeting April-June for 2nd Zhuque-3 launch

10:24 am

Zhuque-3 at launch
Screen capture from China’s
state-run press of the first Zhuque-3
launch on December 2, 2025.

The Chinese pseudo-company Landspace now hopes to make its second orbital launch and recovery attempt of its Zhuque-3 rocket sometime in the April-June ’26 time frame.

The first launch in December ’25 was a success, getting its upper stage into its planned orbit. The attempt to vertically land the first stage however failed. The stage came down almost precisely on its target landing pad, but the engines failed and so it crashed instead of landing softly.

Officials say that they also hope to begin reusing the first stage quickly, if it should land successfully, with the first reuse planned for late this year. The rocket itself has about two-thirds the capacity of SpaceX’s Falcon 9, and is being marketed to launch the half-dozen giant satellite constellations China is presently attempting to place in orbit.

Since the beginning of this year there has been a decided pause of news from China’s pseudo-companies. I have speculated this dearth of the normal stream of PR announcements might be related to a power-play by the new government agency created last year to supervise these pseudo-companies. It also could simply be the government has told them to tone it down a bit. Better to sell actual achievement than empty plans.

The dimmest galaxy yet found

9:57 am

The dimmest galaxy yet found
Click for original image.

The uncertainty of science: Using ground-based and orbiting telescopes, astronomers think they have identified what might be the dimmest galaxy yet discovered, revealed almost entirely not from its stars but from the four globular clusters that reside within or near it.

The image to the right, cropped and sharpened to post here, shows that galaxy, dubbed CDG-2, along with those four globular clusters. From the press release:

To confirm one of the dark galaxy candidates, astronomers employed a trio of observatories: the NASA/ESA Hubble Space Telescope, ESA’s Euclid space observatory, and the ground-based NAOJ Subaru Telescope in Hawaii. Hubble’s high-resolution imaging revealed a close collection of four globular clusters in the Perseus galaxy cluster, 300 million light-years away. Follow-up studies using Hubble, Euclid, and Subaru data then revealed a faint, diffuse glow surrounding the star clusters – strong evidence of an underlying galaxy.

“This is the first galaxy detected solely through its globular cluster population,” said David. “Under conservative assumptions, the four clusters represent the entire globular cluster population of CDG-2.”

Preliminary analysis suggests CDG-2 has the luminosity of roughly 1 million Sun-like stars, with the globular clusters accounting for 16% of its visible content.

The scientists next claim that 99% of the galaxy’s mass is made up of dark matter, a material no one has yet detected except for the gravitational influence its invisible mass imposes on visible objects. It appears the astronomers don’t believe the mass that has been detected is sufficient to hold this galaxy together, and thus they need dark matter to explain its existence.

I simply wonder if the distances involved simply make the matter hard to see.

No matter. This is a cool discovery, because it tells us there is much out there hidden in the darkness we will always find difficult if not impossible to detect.

Engine problems for Japan’s lunar lander company Ispace

9:27 am

According to company officials, the Japanese lunar lander company Ispace is having issues with the engine is has been developing for its next (and third) lander mission — a joint project with the American company Draper — problems that have now delayed the mission from ’26 to ’27.

In an earnings call discussing its fiscal third-quarter financial results this month, ispace executives said issues with development of the new VoidRunner engine could delay the company’s next lander mission. VoidRunner is a joint project between ispace’s U.S. subsidiary and Agile Space Industries, a U.S. space propulsion company, announced in May 2025. It replaced an Agile Space engine originally planned for use on the Apex 1.0 lander that ispace U.S. is developing.

Changing the engine required modifications to the lander design, Ispace said at the time, delaying its use on a mission led by Draper for NASA’s Commercial Lunar Payload Services, or CLPS, program from 2026 to 2027. That mission to the lunar farside is designated Mission 3 by Ispace.

Ispace has made two attempts to land on the Moon. In both cases, the mission worked perfectly until the last moments, resulting in a crash rather than a soft landing. In the first case software had the engines shut down when the spacecraft was still about three miles above the ground, while in the second case the spacecraft’s laser range-finder provided incorrect altitude data.

It presently has contracts for three more missions, the one for NASA working with Draper, a second for Japan in ’28, and a third for Europe in ’29. That it has had to replace the engines on the first (and might have to do it on the second) is a very bad sign. Usually it is best practice to build and test the engine first, get it right, and then build the spacecraft or rocket around it. Replacing an engine usually signals larger design problems that are difficult if not impossible to fix.

The United Arab Emirates (UAE) yesterday announced it is extending the mission of its Al-Amal Mars orbiter (“Hope” in English) to 2028, significantly beyond its initial planned mission of two years.

Launched in July 2020, the Hope Probe successfully entered Mars orbit in February 2021 after a seven-month interplanetary journey, marking a historic achievement as the first Arab nation to reach the Red Planet. Originally designed as a two-year mission to observe and study Mars’ atmosphere, the probe has far exceeded expectations. Since reaching Mars, it has gathered around 10 terabytes of scientific data, shared through more than a dozen datasets with research institutions worldwide.

The probe itself was mostly built by American engineers and organizations, as part of a deal to train UAE students. Once in operation around Mars, the UAE and those students took over almost all operations. It orbits Mars in a very wide orbit, allowing it to study global weather and atmosphere conditions, such as dust storms.

Bahamas allows SpaceX to resume Falcon 9 landings inside Bahamian waters

8:49 am

The Civil Aviation Authority of the Bahamas (CAAB) this week announced that it is allowing SpaceX to resume Falcon 9 landings inside Bahamian waters.

In a statement, CAAB said that one landing is scheduled for Wednesday night between 5:00 pm and 9:30 pm (local time). “All requisite regulatory and environmental reviews and clearances have been completed in accordance with established aerospace safety and operations protocols,” CAAB said, reminding the population that, depending on weather and atmospheric conditions, “one or more sound booms may be heard during the landing sequence”.

SpaceX had completed one landing in February 2025, but the CAAB then paused further landings two months later, claiming it wanted to do a full environmental review.

There was also the issue of a SpaceX $1 million donation to the University of the Bahamas. Maybe the CAAB wanted to wait until the check cleared.

As should be expected, a fringe of anti-Musk activists began screaming “environmental disaster” and getting the full support of the propaganda press. The claim is utterly stupid, considering SpaceX has landed hundreds of Falcon 9s in the past decade harmlessly.

Pluto’s floating mountains of frozen ice

10:18 am

Pluto's floating mountains
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and sharpened to post here, was taken by New Horizons on July 14, 2015 when it made its close fly-by of Pluto.

The picture looks at the part of Pluto that was close to sunset. Hence the mountain’s long dramatic shadow. The raw image webpage provides little information, including a scale of 0.0 meters, which means nothing. My guess is that these mountains could be several hundred to several thousand feet high based on data from other New Horizon mountain images, but that is a pure guess.

What we think we know is that these mountains are likely made of ice, which at Pluto’s eternally cold environment is as hard as granite. We also think we know that they float on a layer of frozen nitrogen, but because that nitrogen can sublimate into gas when Pluto’s climate warms as its orbit brings it closer to the Sun, the foundation of these mountains is quite unstable. They can roll and drift about, even if they are the size of the Appalachian mountains in the eastern U.S.

I continue to delve into the New Horizons’ archive, and have discovered a trove of quite amazing pictures that hadn’t been featured by the science team during the fly-by. Pluto really is an alien place. Stay tuned, there is more to come!

NASA now targeting February 19, 2026 for 2nd SLS wet dress rehearsal countdown

8:20 am

According to an announcement yesterday afternoon, NASA is now targeting February 19, 2026 for the second SLS wet dress rehearsal countdown.

During the rehearsal, the team will execute a detailed countdown sequence. Operators will conduct two runs of the last ten minutes of the countdown, known as terminal count. They will pause at T-1 minute and 30 seconds for up to three minutes, then resume until T-33 seconds before launch and pause again. After that, they will recycle the clock back to T-10 minutes and conduct a second terminal countdown to just inside of T-30 seconds before ending the sequence. This process simulates real-world conditions, including scenarios where a launch might be scrubbed due to technical or weather issues.

If this dress rehearsal goes off perfectly, NASA is considering the possibility of an actual launch attempt on March 6, 2026, though it admits that date is very preliminary That launch will carry four astronauts on a ten-day mission slingshot around the Moon and back to Earth, using an Orion capsule with untested life support system and a questionable heat shield.

The present launch window for this mission closes on April 6th, so NASA’s margins will shrink considerably if this second dress rehearsal has any further problems.

A realistic plan to send a spacecraft to interstellar Comet 3I/Atlas

8:01 am

Scientists have devised a mission profile that could actually get a spacecraft close to Comet 3I/Atlas sometime around 2085.

…the team found that an intercept could be achieved via a Solar Oberth maneuver, but the launch would have to occur in 2035 to achieve optimal alignment between Earth, Jupiter and 3I/ATLAS. The flight duration would be 50 years (though Hibberd notes that this could be reduced marginally). “2035 is optimal because the alignments of the celestial bodies involved (i.e. the Earth, Jupiter, Sun, and 3I/ATLAS) are the most propitious to reach 3I/ATLAS with a minimum Solar Oberth propulsion requirement from the probe, a minimum performance requirement for the launch vehicle, and a minimum flight time to the target,” he said.

The Solar Oberth maneuver has the spacecraft fire its engines at the moment it is zipping past the Sun at its closest and fastest, taking full advantage of that gravitational velocity.

You can read their paper here [pdf] As they note in their conclusion, this entire mission is based on using “a Starship Block 3 upper stage fully-refuelled in Low Earth Orbit.” It assumes that by 2035 Starship will be flying routinely and cheaply, and could be purchased at a reasonable cost for such a mission.

Or maybe donated in the name of science by some billionaire who happens to care about making the human race multi-planetary. Know anyone?

Personally, I wonder it this mission profile could be adapted to reach the first known interstellar object, Oumuamua. 3I/Atlas appears to simply be a comet. Though a visit would be of value it would not Earth-shaking. Oumuamua however was not a comet, but more importantly it was strange in every way. Though astronomers in 2019 declared based on the available data that it was definitely not an alien spaceship, that conclusion remains very uncertain. As I wrote at the time:

…for anyone to assume there is any certainty to this conclusion would be a grave mistake. It is merely the best guess, based on the available but somewhat limited data. The data however does not preclude more exotic explanations. Nothing is certain.

To me this object should get top priority.

A sinuous Martian ridge of uncertain origin

A sinuous ridge of uncertain origin
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 21, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It was posted today by the camera team as a captioned image, with the caption as follows:

The sinuous ridge is approximately 10 meters wide and several kilometers long. The floor surrounding this ridge has been eroding laterally, forming pits and circular features suggestive of removal (sublimation) of subsurface ice. However, landforms such as channels or moraines that might suggest the presence of water or ice are lacking, so the ridge itself does not appear to have formed by fluvial or glacial processes.

Perhaps this curious feature is an exhumed dike formed from magma emanating from Alba Mons in subsurface fractures.

Alba Mons is a gigantic shield volcano to the west.

Rocket Factory Augsburg getting close to launch

9:16 am

Screen capture of test failure
Screen capture from video of test failure in 2024.
Note the flame shooting out sideways.

The German rocket startup Rocket Factory Augsburg appears to finally be getting close to launching its RFA-1 rocket after a static fire test explosion in 2024 seriously delayed its plans.

Speaking to European Spaceflight in early February, Rocket Factory Augsburg CEO Prof. Dr. Indulis Kalnins, who replaced Dr. Stefan Tweraser in April 2025, explained that the rocket’s first stage is in the process of being transported from Augsburg in Germany to the launch site on Unst. The rocket’s upper stage, which has received upgrades to its single Helix engine and the associated control software, is expected to follow in the next few weeks.

On 10 February, the company announced that the new umbilical tower had been raised, standing at 52 metres high. The tower will support and stabilise the rocket and provide propellant, power, and data connections. The company has begun commissioning the repaired and upgraded launch pad. The only element still to be added is the water tanks for the water deluge system. Kalnins, however, stressed that the company is taking its time with all pre-flight testing.

It appears my speculation that the company had not yet received its launch licenses from the Civil Aviation Authority (CAA) was wrong. Those licenses were issued in January 2025, only five months after the static fire launchpad explosion. For the CAA to respond that quickly is quite surprising. Maybe it decided it shouldn’t kill a third rocket company trying to launch from the UK.

Right now the race to be the first orbital rocket launched from a European spaceport is coming down to Rocket Factory and its German competitor Isar Aerospace. Isar is gearing up to make its second attempt to launch its Spectrum rocket from Norway’s Andoya spaceport in March.

Fairing from India’s Bahubali rocket launched in December found in Maldives

9:00 am

A man fishing off an uninhabited island in the Maldives discovered what appears to be pieces from the fairing used by India’s LVM3 rocket, also dubbed Bahubali, when it launched AST SpaceMobile’s sixth Bluebird satellite in December.

A similar discovery was made on December 28, 2025 in Sri Lanka. In both cases it is theorized that the material came from the fairings of the December Bahubali launch.

I am unable to determine the flight path of the Bluebird launch, but the location of this debris suggests it headed strongly south from India’s east coast spaceport. The fairing pieces then drifted south and west to reach the Maldives after two months.

SpaceX routinely recovers its fairing and resuses them, which due to the fairing’s basic shape has turned out to be relatively straightforward. They have the shape of a boat’s hull, and after parachuting softly down can simply float on the surface until they can be picked up. It is absurd no one else does this.

Chinese pseudo-company raises $729 million

10:35 pm

The Chinese pseudo-company rocket startup Ispace announced on February 13, 2026 that it has raised $729 million in new investment capital.

Beijing Interstellar Glory Space Technology Ltd., also known as iSpace, announced the D++ funding worth 5.037 billion yuan Feb. 12, following a D+ round of $98 million (700 million yuan) in September 2025. The round appears to be the largest disclosed funding round so far for a Chinese launch startup, eclipsing the previous rounds secured by Space Pioneer ($350 million) and Galactic Energy ($336 million) in 2025.

A press statement outlines a hybrid syndicate of numerous funding round participants, incgovernment industrial funds, state-linked strategic ecosystem investors, municipal and provincial investment vehicles and private equity. This follows a trend of strong strategic investment in space companies in China over the past couple of years since the central government identified commercial space as a strategic emerging industry and key driver of high-tech development. Co-leads Tongchuang Weiye and existing shareholder Jingming Capital represent market-oriented investors focused on advanced manufacturing and aerospace, and were joined by repeat backing from private equity players such as CDH Baifu and Ganquan Capital. [emphasis mine]

It is hard to determine how independent these Chinese investment firms are from the government. I suspect the communists are closely involved in some manner or another.

The press release made no mention of a timeline for when Ispace will attempt the first launch and recovery of its Hyperbola-3 rocket. It had previously targeted a 2025 launch, but that never happened.

NASA testing SLS fuel leak repairs; UPDATE: Problems!

10:33 am

UPDATE: NASA posted a late update today describing vaguely the results of this fueling test, and revealed that while the test of the replacement seals appeared to go well, there were other problems:

During the test, teams encountered an issue with ground support equipment that reduced the flow of liquid hydrogen into the rocket. … Engineers will purge the line over the weekend to ensure proper environmental conditions and inspect the ground support equipment before replacing a filter suspected to be the cause of the reduced flow.

In other words, the SLS fueling system is like playing whack-a-mole. You fix one problem, and others show up.

I predicted this. It remains entirely possible NASA will not be able to complete a perfect full wet-dress rehearsal countdown in time to launch before April 6th, when this present launch window closes.

Original post:
———————-
NASA yesterday did an unannounced test fueling of its SLS rocket to check out the repairs in the fueling system.

NASA is loading liquid hydrogen aboard its Space Launch System moon rocket at the Kennedy Space Center on Thursday for an unpublicized but crucial test of the repairs made to a leaky umbilical that derailed a countdown rehearsal on Feb. 2.

The operation to load liquid hydrogen into the huge fuel tank on the rocket’s core stage was thought to be already underway at launch complex 39B on Thursday morning. The test will determine if new seals installed in the launch pad umbilical are working. “As part of our work to assess the repair we made in the area where we saw elevated hydrogen gas concentrations during the previous wet dress rehearsal, engineers are testing the new seals by running some liquid hydrogen across the interface and partially filling the core stage liquid hydrogen tank. The data will inform the timeline for our next wet dress rehearsal,” a NASA spokesperson said about the previously unannounced test.

If the new seals work on these fueling tests, another full dress rehearsal countdown could take place as early as next week.

Posting is going to very light for the rest of the day. I am fighting a bad head cold and just want to go back to bed.

FAA confirms “no significant impact” to environment for Starship/Superheavy at Boca Chica

9:42 am

The FAA today released [pdf] its final environmental assessment reviewing SpaceX’s request to expand operations of Starship/Superheavy at Boca Chica, confirming that it has determined there will be “no significant impact” to environment.

The 2022 PEA and April 2025 Tiered EA examined the potential for significant environmental impacts from Starship-Super Heavy launch operations at the Boca Chica Launch Site and defined the regulatory setting for impacts associated with Starship-Super Heavy. The areas evaluated for environmental impacts in this Tiered EA include noise and noise‐compatible land use; aviation emissions and air quality; hazardous materials, solid waste, and pollution prevention; and socioeconomics. In each of these areas, the FAA has concluded that no significant impacts would occur as a result of the Proposed Action.

The approval will allow SpaceX to do 25 launches per year (three of which are at night). The approval also appears to lay the groundwork for bringing Superheavy back not only to Boca Chica, but to Florida. It also lays the groundwork for bringing Starship back to Boca Chica after completing an orbital flight, to be caught by the tower chopsticks.

Vast wins sixth ISS slot for tourist mission

5:11 pm

Haven-2
Vast’s full Haven-2 station once completed

NASA today announced that it has awarded the space station startup Vast its sixth slot for a manned commercial mission to ISS, scheduled for 2027.

The mission is expected to spend up to 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.

…Vast will submit four proposed crew members to NASA and its international partners for review. Once approved and confirmed, they will train with NASA, international partners, and SpaceX for their flight. The company has contracted with SpaceX as launch provider for transportation to and from the space station.

Vast already intends to fly four two-week missions to its single module Haven-1 demo station, scheduled to launch in the first quarter of 2027. This new ISS mission will demonstrate to NASA directly that Vast can handle manned missions. In both cases, the company is hoping its actions will convince NASA to award it a full construction contract to build its Haven-2 full-sized station, as shown in the graphic to the right.

Below are my rankings of the five private commercial space stations being developed. At this point the first three (Haven, Axiom, Starlab) are essentially tied, while the fourth (Thunderbird) is only trailing because it came late to the game. The fifth, Orbital Reef, seems practically out of the game.

Four launches today with mostly positive results

10:15 am

This morning saw a string of launches from China, Russia, America, and Europe, with all four appearing to get their payloads into orbit though the American launch, by ULA’s Vulcan rocket, appeared to have a problem with one of its solid-fueled boosters.

First, a Chinese pseudo-company owned entirely by a Chinese government agency successfully placed seven satellites in orbit, its Smart Dragon-3 rocket (also called Jielong-3) lifting off from a platform off the coast of northeast China. Of the satellites, the prime payload was a Pakistani Earth observation satellite.

Though this launch was from a pseudo-company, I think I can safely say that the pause in launches by China’s so-called commercial market continues. Smart Dragon-3 was built by the China Aerospace Science and Technology Corporation (CASC), which while structured as a private company is owned and controlled by several agencies of the Chinese government.

Next, Russia successfully launched a new weather satellite, its Proton rocket launching from Baikonur in Kazakhstan. This was the first Proton launch in three years, a pause partly because Russia is in the process of retiring that rocket. The lower stages crashed in a range of spots in Kazakhstan and across southern Russia, just missing China in two places.

The American company ULA then followed with its first launch in 2026, its Vulcan rocket lifting off from Cape Canaveral in Florida and carrying two military satellites designed to track other satellite operations in high geosynchronous orbit.

Unexpected debris falling from rocket at about T-1:00
Unexpected debris falling from rocket at about T-1:00

While it appears the launch was able to get the satellites into their correct orbits, the Vulcan rocket had an issue during the launch. According to ULA, one of the rocket’s four solid-fueled boosters had a problem during its flight. More details can be found here, suggesting the booster, built by Northrop Grumman, might have had a been a failure of the booster’s nozzle, similar to the same burn-through that occurred on a booster during Vulcan’s second launch in 2024, and also occurred during a Northrop Grumman static fire test in 2025.

This issue is likely going to delay further Vulcan launches, and will likely make it impossible for ULA to meet its goal of launching 16 to 18 Vulcan missions this year. It will also raise hackles within the Pentagon, which certified Vulcan for military launches in 2025. That certification will likely be questioned, and possibly even pulled.

Finally, Arianespace sent 32 Leo satellites into orbit for Amazon, its Ariane-6 rocket lifting off from French Guiana. This was the first Ariane-6 launch in its most powerful variant, using four strap-on boosters.

Amazon has now launched 212 Leo satellites. Its FCC license however requires it to have 1,616 in orbit by July. The company has requested a waiver on that requirement, and is likely to get it, since it is now demonstrating that it is serious about launching the constellation.

The 2026 launch race:

16 SpaceX
8 China
2 Rocket Lab
2 Russia
1 ULA
1 Europe (Arianespace)

British rocket startup Skyrora might buy Orbex assets

9:24 am

The British rocket startup Skyrora, which has been around since 2018 and has yet to complete an orbital launch, today indicated it might buy the remaining assets of the now bankrupt British rocket startup Orbex.

The company, which has a manufacturing facility in Cumbernauld, said its move would ensure Orbex technology and the spaceport remained under UK ownership. It also said its bid would safeguard products that had received public funding.

Skyrora has been making promises for almost a decade with no clear progress. It did two successful suborbital tests in 2020 (here and here), had a failed suborbital test in 2022, and applied for an orbital launch license with Britain’s Civil Aviation Authority (CAA) in January 2024. Not surprisingly, it is unclear whether that license has been approved. The company said last year it wants to do that orbital launch in ’26 from the Saxavord spaceport in the Shetland Islands. That gives the CAA two years to approve the license, which based on that agency’s track record might be enough time to get the job done. Or not.

Getting Orbex’s assets might actually be a good thing for Skyrora, which has not been very successful getting anything going with its own engineering. It will still face that odious regulatory regime of the United Kingdom, that has now killed two different rocket startups.

Engineers have shut down the Gehrels-Swift space telescope in a last attempt to save it

In order to delay the moment the orbit of the Gehrels-Swift Observatory decays — to increase the chance a rescue mission can get there in time — engineers have now stopped almost all scientific observations temporarily.

On Feb. 11, NASA’s Neil Gehrels Swift Observatory temporarily suspended most science operations in an effort to reduce atmospheric drag and slow the spacecraft’s orbital decay. Halting these activities will enable controllers to keep the spacecraft in an orientation that minimizes drag effects, extending its time in orbit in anticipation of a reboost mission.

“Normally, Swift quickly turns to view its targets — especially the fleeting, almost daily explosions called gamma-ray bursts — with multiple telescopes,” said principal investigator S. Bradley Cenko at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Swift’s Burst Alert Telescope will continue to detect gamma-ray bursts, but the spacecraft will no longer slew to observe targets with its other telescopes.”

…To maximize the orbit boost’s chances of success, Swift’s average altitude needs to be above about 185 miles. As of early February, Swift’s average altitude had fallen below about 250 miles.

NASA has awarded the orbital repair startup Katalyst the contract to rescue Gehrels-Swift, but the company has a very challenging mission. It got the contract only a few months ago, in September 2025, and is refitting its planned satellite rescue demo mission to save the space telescope instead. The graphic to the right shows how its rescue robot will approach and grab Gehrels-Swift to raise its orbit, but it must be noted that the telescope has no planned grapple points, and Katalyst’s robot has never done this before.

Moreover, the robot will be launched using the last Pegasus rocket in Northrop Grumman’s warehouse, with a launch scheduled now for sometime this summer. That means Katalyst has had to go from contract award to launch in less than a year, a pace that up until now has been unheard of in the space business. If successful however Katalyst will once again demonstrate the benefits of the capitalism model, whereby NASA buys the product from the private sector rather than building it itself. Left to NASA, this rescue mission would never happen.

And even if Katalyst’s rescue fails, that the company could get it built and launched in such a short time still proves the value of the capitalism model. Freedom and capitalism and competition at least made the attempt possible.

SpaceX completes extensive tank tests on next Superheavy booster

1:05 pm

Link here. The story details the repeated tank tests just completed on Superheavy booster prototype #19, intended to fly on the 12th Superheavy/Starship test flight now targeting a mid-March launch.

The article also describes the extensive repairs and upgrades to the Massey test stand facility following the explosion during a static fire test in 2025.

It does appear that the issues that caused the two recent blow-outs of Superheavy boosters in the past few months have been fixed, and that flight testing will resume in about a month.

A sculptured Martian landscape

Weird Martian landscape
Click for original.

Cool image time! The picture to the right, cropped and sharpened to post here, was taken on December 4, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this landscape “olivine-rich plains”, which is a magnesium iron silicate mineral of some industrial value that is quite common on Earth. Its presence here suggests there could be other valuable minerals in this region.

I post the image because the landscape is so weird and beautiful. The orange color suggests these ridges are covered with dust, if not made of dust entirely. The small areas with a greenish tint that appear to mostly appear on north-facing cliffs could be frost, except this is in the southern hemisphere where north-facing cliffs get more sunlight. As it was autumn when this picture was taken frost is an unlikely explanation.

More likely the green indicates exposures of bedrock or coarser boulders.

SpaceX launches 24 more Starlink satellites

10:17 am

SpaceX today successfully launched another 24 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its third flight, landing on a drone ship in the Pacific.

The 2026 launch race:

16 SpaceX
7 China
2 Rocket Lab
1 Russia

These numbers will definitely change in the next 24 hours, as there are launches planned from China, Russia, Europe, and ULA tomorrow, and a SpaceX Dragon manned launch to ISS the next day.
