Ariane-6 gets more launch contracts

9:14 am

Despite high launch cost of the Ariane-6 rocket, the European Space Agency (ESA) this week arranged three more launch contracts with Arianespace, which manages the rocket.

During the 17th European Space Conference, held in Brussels on 28 and 29 January, Arianespace was awarded contracts to launch PLATO [an ESA science mission to study exoplanets], Sentinel-1D [an ESA Earth observation satellite], and a pair of second-generation Galileo satellites. [part of ESA’s GPS-type satellite constellation]. Arianespace currently has a backlog of 30 Ariane 6 launches, 18 of which are for Amazon’s Kuiper constellation.

These new launch deals are expressly because ESA wants to force feed contracts to Ariane-6 to keep it whole, as part of its policy to launch its European payloads on European rockets. The result is that ESA is also forced to pay too much for its launches. Note too that these payloads are expressly ESA science or research projects, which also applies to most of Ariane-6’s backlog of launches outside of its Kuiper launches. Profit is not the main goal of these payloads. I doubt this rocket will get much additional business from commercial satellite companies that must make a profit to survive. It costs too much.

This is also the reason ESA member nations Germany, Italy, France, and the United Kingdom are pushing hard to get new European private rocket startups operational. They don’t like being forced to pay too much for launches, and want commercial options outside of Ariane-6.

For the moment however ESA is propping up Ariane-6 and Arianespace. It means Ariane-6 will be around for awhile, even as it limits what ESA can do in space.

SpaceX launches Spanish communications satellite

7:06 pm

SpaceX tonight successfully launched the first satellite in a constellation of two Spanish communications satellites, the Falcon 9 rocket lifting off from the Kennedy Space Center in Florida.

The first stage completed its 21st flight. Because of the fuel needed to get the satellite into its proper orbit, the stage was not recovered.

Astroforge names the target asteroid for its first commercial interplanetary mission

3:48 pm

The asteroid mining startup Astroforge today finally named the asteroid that its first commercial interplanetary mission will do a close fly-by, set to launch as a secondary payload on a SpaceX Falcon 9 on February 26, 2025.

The mining startup is headed to asteroid 2022 OB5 as soon as Feb. 26, launching alongside Intuitive Machines’ second lunar mission. CEO Matt Gialich told Payload that they picked that asteroid for the initial mission for a few reasons:

  • It’s under a kilometer wide.
  • It could be a high-value, metal-filled M-type asteroid.
  • AstroForge’s spacecraft will fly by the asteroid when it’s close to Earth, so imagery can be sent back quickly.

This will be Astroforge’s second mission, the first being an Earth-orbit demo flight to prove out its systems. The spacecraft, dubbed Odin, was quickly prepped when the planned satellite satellite failed vibration testing. The company quickly replaced it with the cubesat intended for the third mission.

The company is also proud that the entire cost for this asteroid mission is just $6.5 million. “Hopefully we’re going to show the world that NASA doesn’t need to be funded for $5B missions when we can do it for much less,” said Gialich. The company also announced it has signed a multi-launch contract with the rocket startup Stoke Space, though no specifics were released.

Apple joins T-Mobile’s project to use Starlink satellites as orbiting cell towers

12:52 pm

In releasing a new update on its Iphone operating system, Apple quietly revealed that it has joined T-Mobile’s partnership with SpaceX to use a subconstellation of Starlink satellites with direct-to-cellphone capability, thus acting as orbiting cell towers to fill in gaps in T-Mobile’s service.

Originally spotted by Bloomberg, it seems that Apple has secretly worked with SpaceX and T-Mobile U.S. to provide an alternative satellite service. This is quite a surprise, as T-Mobile had previously specified Starlink as an option for Samsung phones, like the Galaxy S25 Ultra and the Galaxy Z Fold 6. Meanwhile, Apple has an in-house Satellite connection service due to a partnership with Globalstar Inc.

However, the Bloomberg report states that a select number of iPhone users have been able to enable the Starlink beta through T-Mobile. While we don’t know which models will be compatible as of yet, T-Mobile told Bloomberg that the full release will support the vast majority of iPhones.

The system is being tested right now, but still requires FCC license approval.

Musk posts a silly tweet saying Trump wants SpaceX to rescue the Starliner astronauts and the press goes stupid again

10:51 am

Yesterday Elon Musk posted what appeared to be a completely silly tweet stating that Trump “has asked SpaceX to bring home the 2 astronauts stranded on the Space_Station as soon as possible. We will do so. Terrible that the Biden administration left them there so long.”

Since a Dragon capsule for bringing these astronaut back to Earth is already docked to ISS and is scheduled to return in April, there is nothing really new about Musk’s tweet. Moreover, that April return was delayed an extra two months because of SpaceX, not Boeing or Biden. The company had requested that extra time to prepare the next crew capsule for launch, because it is a new capsule never used before.

It is of course possible that Trump requested SpaceX and NASA to reconsider this extra two month delay, and move the crew return back to February, but that change would either require SpaceX to find a different older capsule for the next crew, fly the new capsule sooner than planned, or have the total number of NASA astronauts on ISS reduced to just one until the new capsule launches with the new crew in March. None of these options seems wise.

I suspect nothing will change, and Musk was merely trolling the press. And the press mostly fell for it, hook, line, and sinker.

Most of these stories fail to outline the reasons for the most recent delays, having nothing to do with Biden. The last four especially make it sound as if SpaceX has suddenly been enlisted for a rescue mission, a claim that is utterly false.

None have been able to get any confirmation of any change of schedule from NASA or SpaceX, suggesting that Musk’s tweet was entirely blarney that a smart press would have ignored without that confirmation. Our stupid mainstream press however could not do that. It went whole hog based on nothing.

Until NASA announces a change in schedule there simply is no story here, and that’s what I am reporting.

200-foot-wide asteroid has a 1-in-83 chance of hitting the Earth in 2032

10:12 am

New data that has refined the solar orbit of 200-foot-wide asteroid discovered in 2024, dubbed 2024 YR4, suggests it has a 1-in-83 chance of hitting the Earth on December 22, 2032.

“Odds have slightly increased to 1 in 83,” Catalina Sky Survey engineer and asteroid hunter David Rankin wrote on BlueSky. “This is one of the highest probabilities of an impact from a significantly sized rock ever.”

Amateur astronomer Tony Dunn shared a simulation of the asteroid approach on his X feed. “Recently-discovered #asteroid 2024 YR4 may make a very close approach to Earth in 8 years. It is thought to be 40-100 meters wide. Uncertainty is still high and more and more observations are needed confirm this.”

The asteroid is rated three on the Torino risk scale, which indicates a close encounter that warrants close attention from astronomers and an over 1% chance of impact.

Though most reports say the asteroid is about 200 feet across, there is great uncertainty in that number. It could also be as large as 320 feet, or as small as 130 feet.

At the moment the risk of impact is still small. If it does occur, there is a chance it could either cause a major airburst similar to the Chelyabinsk meteor impact in 2013 that injured more than 400 people, or even impact the ground or ocean. If it hits the ocean there is a considerable risk of tsunamis. At the moment it appears its path will cross from South America to Africa in the southern hemisphere, but this data remains very uncertain at this time.

Though there will be doom-sayers, overall this is not a world destroyer. It carries some risk, but we have eight years to refine our knowledge significantly, especially when it will make a close approach of five million miles in 2028. At that time scientists should be able to better measure its size as well as its future orbit, determining more precisely whether it will even hit the Earth in 2032.

Using Juno’s Italian JIRAM infrared instrument image as well as its optical camera, scientists have detected what appears to be the largest volcanic event yet measured on the Jupiter moon Io, covering an area larger than Lake Superior,

Scientists with NASA’s Juno mission have discovered a volcanic hot spot in the southern hemisphere of Jupiter’s moon Io. The hot spot is not only larger than Earth’s Lake Superior, but it also belches out eruptions six times the total energy of all the world’s power plants.

…The JIRAM science team estimates the as-yet-unnamed feature spans 40,000 square miles (100,000 square kilometers). The previous record holder was Io’s Loki Patera, a lava lake of about 7,700 square miles (20,000 square kilometers). The total power value of the new hot spot’s radiance measured well above 80 trillion watts.

The pictures above were taken by Juno’s optical camera during the last three close flyby’s, looking down at the south pole, with the red arrows indicating the change to the pole’s right during each pass. The infrared image to the right shows a similar view during the fly-by, and shows that same hot spot as the bright area to the pole’s right.

Juno will do another fly-by of Io in March, though from a greater distance. Scientists plan to use both instruments to see how this hot spot has changed again since the end of December.

United Kingdom awards rocket startup Orbex $25 million

9:29 am

The government of the United Kingdom has made a sudden and unexpected $25 million grant to the British rocket startup Orbex, which recently announced it was abandoning its launchpad at the Sutherland spaceport and switching to the Saxavord spaceport on the Shetland Islands.

While the UK Government has supported Orbex through grants awarded via the European Space Agency’s Boost! programme, the £20 million investment appears to represent the state acquiring a stake in the company and its future. This signals a significant show of support from the government as the company gears up to compete in the European Launcher Challenge.

Channeling former NASA Administrator Jim Bridenstine, Technology Secretary Peter Kyle declared that the government’s backing of Orbex would enable the launch of “British rockets carrying British satellites from British soil.”

It seems to me that this cash award is less an investment in the company and more a kind of guilt payment by the United Kingdom government because the red tape of its bureaucracy, the Civil Aviation Authority, prevented Orbex from launching at Sutherland for almost three years, delays that eventually forced the switch to Saxavord, which after its own long red tape delays finally has its license approvals not yet issued to Sutherland.

Orbex has probably indicated to the government that these delays have caused it significant cash flow problems, similar to what happened to Virgin Orbit where red tape delays eventually drove it to bankruptcy. The company also probably told the government it needed extra cash to prepare the launchpad at Saxavord for its rocket, money it had already spent at Sutherland and no longer had.

Thus, this $25 million government grant. The UK government realized that if a second rocket company went belly-up due to its red tape, it would likely end forever any chance of getting any rocket company from considering launching from the United Kingdom.

Firefly’s Blue Ghost lunar lander has successfully completed its second orbital burn, raising its Earth orbit in preparation for its shift into lunar orbit in the coming weeks.

Routine assessments while Blue Ghost is in transit show that all NASA payloads continue to be healthy. Firefly and NASA’s payload teams will continue to perform payload health checkouts and operations before reaching the Moon, including calibrating NASA’s Lunar Environment Heliospheric X-ray Imager (LEXI), continued transit operations of the Lunar GNSS Receiver Experiment (LuGRE), and analysis of radiation data collected from the Radiation Tolerant Computer (RadPC) technology demonstration.

The picture to the right looks across the top of Blue Ghost, with the small bright object beyond its first image of the Moon. The actual landing is at least four weeks away.

The blobby bottom of Utopia Basin

The blobby bottom of Utopia Basin
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 25, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely as a “terrain sample,” it was likely taken not as part of any specific research project, but to fill a gap in the camera’s schedule so as to maintain the camera’s proper temperature.

The terrain is definitely blobby, with some hollows appears to have ripple dunes suggesting dust and sand. The rounded mounds and some hollows however suggest instead near surface ice or places where sublimation of that underground ice caused the hollows.

Some of the circular depressions might suggest impact craters, but if so, those craters have been significantly modified and softened since impact. Some do appear to be filled with glacial debris.

Arianespace to launch Ariane-6 five times in 2025, with the first launch targeting February 26th

9:27 am

Arianespace now plans to launch the Ariane-6 rocket five times in 2025, with the first launch scheduled for February 26, 2025.

On 13 and 14 January, the Ariane 6 core stage stack and two solid-fuel boosters were successfully brought together on the ELA-4 launch pad. While this process was occurring, an Antonov transport plane touched down at Felix Eboué Airport carrying the rocket’s payload, the CSO-3 reconnaissance satellite.

This will be the first commercial payload launched by Ariane-6, a military reconnaissance satellite for France.

In addition, the Vega-C rocket is scheduled for six flights, though some of those flights might be arranged and controlled by the rocket’s Italian builder, Avio, not the European Space Agency’s commercial arm, Arianespace. Sometime in the next two years Arianespace’s responsibiilty for Vega-C is being phased out, so that Avio will own and sell all further launches.

Firefly planning five launches from Vandenberg in 2025

9:00 am

In announcing its plans to begin launches from both Wallops Island in Virginia and Esrange in Sweden in 2026, Firefly has also said it is planning five launches from Vandenberg in 2025.

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

The company is also building a launchpad at Cape Canaveral, so if these plans reach fruition it will eventually have four different launch sites. One issue for all these sites remains red tape. For example:

[Firefly VP Adam] Oakes said Firefly is continuing to work on regulatory issues for launches from Esrange. “The regulatory piece can really put you back if you want to let it,” he said. “We have a lot of paperwork in place. We’re not quite there on everything but things are moving in the right direction.”

One serious problem for Esrange is its interior location in Sweden. Any orbital launch will have to cross land, with most crossing significant territory of other countries. While the site has been used for decades for suborbital test launches, no orbital launches have ever taken off from there, and getting clearance will not be easy for orbital rockets to cross either Norway, Finland, or Russia. And unless the lower stages are reusable they will have to crash inside those territories, or inside Sweden itself.

SpaceX today successfully launched another 21 Starlink satellites, including 13 with direct-to-cell capabilities, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 20th flight, landing on a drone ship in the Atlantic. At this time the first iteration of the direct-to-cell Starlink sub-constellation is largely complete, and the company has begun beta testing using these satellites directly with smartphones on Earth.

Cool image time! The panorama above was created by me using three pictures taken today (here, here, and here) by the right navigation camera on the Mars rover Perseverance. The top of the rover can be seen to the right, as well as its tracks.

The overview map to the right provides the context. The blue dot marks Perseverance’s present position. The white dotted line its past travel route, with the red dotted line indicating the planned route. The yellow lines indicate the approximate area covered by the panorama.

Though the planned route had the rover head west and then south, the rover team instead had the rover retreat eastward about 450 feet the past few days, where it sits now. At the previous western location the team had attempted to find a location to drill a sample core, but apparently the ground was not satisfactory. By retreating to this previous location it could be they think they will have better luck.

What strikes me about this hilly terrain just outside Jezero Crater is its barrenness. You would have great difficulty anywhere on Earth finding terrain so empty of life. On Mars however there is nothing but dirt and rocks, for as far as the eye can see.

Strap-on booster of Long March 3B launched yesterday crashed next to home

9:53 am

Long March 3B
Long March 3B

One of the four strap-on boosters used by a Long March 3B rocket that was launched yesterday from the Xichang spaceport in southwest China ended up crashing right next to a home.

The TJS-14 satellite launched on a Long March 3B rocket from Xichang Satellite Launch Center on Thursday at 10:32 a.m. EST (1532 GMT; 11:32 p.m. local time). The satellite is safely on its way to geostationary orbit, but one of the rocket’s four strap-on side boosters fell to Earth in a populated area of Zhenyuan County in Guizhou province.

Security camera footage posted on the social media platform Sina Weibo captured the scene of two family members reacting to an explosion near their home that lit up the night sky. Fortunately, the booster, which exploded on impact, fell in what appeared to be hills above the house.

The video can be viewed here. While the booster apparently missed the house, any remaining hypergolic fuel in the booster posed a very serious health threat, especially if it was released as a gas. That fuel is extremely toxic, and can dissolve skin if it makes contact. I would expect that until a major clean-up occurred at the crash site, the people that lived in that home will have to evacuate.

China has said that it intends to replace all of its hypergolic-fueled rockets with liquid-fueled, and is expanding operations at its Wenchang coastal spaceport as well. When however these rockets stop launching from its interior spaceports remains unknown. It is likely in fact that toxic stages will continue to fall on the heads of Chinese citizens for years to come.

European rocket startups team up to send letter to ESA outlining their priorities

11:18 am

In a surprising joint action, six European rocket startups have sent a detailed letter to the European Space Agency (ESA) outlining several recommendations about policy required by these rocket startups in order for their industry to prosper.

The companies involved were HyImpulse, Latitude, MaiaSpace, Orbex, Rocket Factory Augsburg and The Exploration Company. The letter’s recommendations were wide-ranging and appeared focused on getting ESA to free up the industry from traditional European red tape.

  • Provide funding in the range of €150 million to a limited number of rocket companies, not all. The companies say that funding will make it possible for the winning companies to raise another €1 billion in private investment capital. Limiting the number of companies getting awards will also force competition and achievement. The awards should also be granted only after specific milestones are achieved, not based on promises of eventual achievement.
  • Ease access to launchpads both at French Guiana and in Norway and the United Kingdom. Right now French rule-making at French Guiana is hindering that access, and ESA rules about launches make it harder to use the new commercial spaceports in Norway and the UK.
  • Red tape must be reduced. For example, ESA should not set rules on the size of payloads, but give companies “the freedom to determine their payload capabilities, allowing market dynamics to drive innovation rather than imposing artificial requirements.”

That the German rocket startup Isar Aerospace did not sign this letter is interesting, especially since it is now only a few months from completing its first orbital test launch of its Spectrum rocket from the new spaceport in Andoya, Norway. It also has a twenty-year lease for that launchpad.

It is also interesting that the letter did not include the newly proposed orbital spaceport Esrange in Sweden. That launch site has been used for decades for suborbital tests. It is now attempting to make itself available for orbital tests as well. Its interior location however is likely the reason these rocket companies left it out. Too many issues for them to consider launching from there.

Engineers confirm OSIRIS-APEX successfully completed its second of six close fly-bys of the Sun

10:19 am

Engineers have now confirmed that the asteroid probe OSIRIS-APEX successfully completed its second of six close fly-bys of the Sun in September, using its solar panels to shield its instruments from the Sun’s heat and light.

On Jan. 23 the mission team completed its review of all the data recorded by the spacecraft and its instruments during the solar pass [about 46 million miles from the Sun]. “There were no surprises, and the spacecraft is operating well,” said Mike Moreau, OSIRIS-APEX deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

As planned, on Sept. 2, 2024, OSIRIS-APEX passed through perihelion — the phase of its orbit closest to the Sun. The trajectory to Apophis takes the spacecraft much closer to the Sun than it was originally designed for. Between Aug. 1 and Oct. 13, the spacecraft was configured in a special orientation that uses one of the solar arrays to shade the most heat-sensitive components, keeping them within safe operating temperatures.

Because of the improvised orientation during the close approach, full data communications was not possible until months afterward. Only now have engineers completed their analysis.

OSIRIS-APEX original mission was to visit the asteroid Bennu and return samples from it to Earth. Once that mission was successfully completed, the probe was repurposed to go to the potentially dangerous asteroid Apophis when it makes its next close approach to the Earth in April 2029.

I have embedded below a short video showing the spacecraft’s journey to get to Apophis.

China and SpaceX complete launches

10:02 am

Both China and SpaceX successfully completed launches since last night.

First, China placed a classified technology communications test satellite in orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China. No further details about the satellite were released. Nor did China’s state-run press provide any information about where the rocket’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China. UPDATE: One of the four strap-on boosters crashed next to a home.

Then SpaceX this morning launched 23 more Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 23rd flight, landing on a drone ship in the Pacific.

Space Perspective needs new investors

9:50 am

According to this news article today, the high altitude balloon company Space Perspective is in need of new investment capital, and its apparent lease default in the Cape Canaveral area is because the company has apparently shifted operations about ninety miles south because costs there are lower.

Space Perspective co-founder Jane Poynter told OBJ in a Zoom interview in December that although Port Canaveral “is our home port” and “we’re very committed to the community we work in” the company had been operating out of Fort Pierce, nearly 90 miles south, for several months. “They are having to struggle with how they balance what’s happening with the cruise industry and space industry growing like gangbusters,” she said of the Space Coast. “It’s so congested that we can’t actually stay there.”

While the company claims it is still moving forward, it has had to lay off most of its staff as it tries to find more investment capital. While it also claims it will return to full staffing when that investment arrives, the question is whether it will arrive. At this moment the default of $90,295 in rent to Titusville-Cocoa Airport Authority is not a good look at all.

AST SpaceMobile raises $400 million in capital

9:33 am

The direct-to-cell satellite company AST SpaceMobile has raised another $400 million in investment capital, giving it a total of $900 million in cash on hand for building its full constellation of its much larger second generation Bluebird satellites.

The operator now has more than $900 million of cash on its balance sheet to shift production of its Block 2 BlueBird satellites into a higher gear this year, after deploying five smaller Block 1 spacecraft to low Earth orbit (LEO) in September.

At about 223 square meters when fully deployed, a Block 2 satellite is significantly larger than Block 1, which spans 64 square meters, enabling 10 times the capacity to support up to 120 megabits per second (Mbps) peak data rates.

It has plans to launch 45 of these larger satellites in the next two years.

At the moment AST SpaceMobile and SpaceX are the only two companies offering direct-to-cell service. One component of SpaceX’s Starlink constellation has this capability, and the company has a deal with T-Mobile to use it to fill in gaps in its cell tower ground network. AST in turn has a deal with AT&T.

Report predicts both Boeing and Airbus will sell off their space divisions this year

9:23 am

According to an analysis of industry trends by the company Space Capital, it predicts that both Boeing and Airbus will sell off their space divisions this year.

According to Space Capital’s latest investment trends report released Jan. 23, these aerospace giants are struggling to maintain pace with the rapidly evolving space sector. “These divestitures by entrenched government contractors marks a pivotal moment in the space economy, as it changes the competitive landscape, establishes a new power broker system, and creates new opportunities and risks in the government’s extended capabilities in space,” the report states.

This prediction for Boeing is not a surprise, especially as the company has also recently announced it expects to take a $1.7 billion loss in the fourth quarter of 2024 from five different program in its Defense, Space and Security business unit.

Most of those charges will go towards two programs: $800 million for the KC-46A tanker and $500 million for the T-7A trainer aircraft. That leaves $400 million in charges for Starliner as well as the VC-25B presidential aircraft and MQ-25 drone.

Airbus’s space division is likely in trouble because of the failure of its Ariane-6 to compete successfully in the modern launch market. It has obtained some launch contracts, but not as many as expected because, as an expendable rocket, it costs too much to launch.

Peeling flood lava on Mars

Peeling flood lava on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 2, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this “enigmatic terrain” because its origins are a bit difficult to decipher. The location is just north of the equator, so this is in the dry tropics of Mars, where no near-surface ice is found at all. The location is also in the middle of Elysium Planitia, one of the largest flood lava plains on Mars. Elysium is a largely featureless flat plain, where flood lava from the large giant Martian volcanoes covered a vast region.

Here however that top layer of flood lava appears almost like peeling paint that failed to stick to the underlying rougher terrain. In many places it is gone, exposing a stippled surface that is also likely flood lava but laid down either in a rougher manner or eroded over time to leave a rougher surface.

Rocket Lab wins launch contract with German satellite constellation

8:58 am

Rocket Lab has won a launch contract with the German satellite constellation Orora Technologies,with the launch to occur only four months hence and place eight satellites into orbit.

The constellation is focused on monitoring wildfires for fire-fighting teams, and will eventually have 100 satellites in orbit.

OroraTech is developing a constellation of satellites with thermal infrared cameras that can provide 24/7 monitoring of wildfires globally, supporting better and faster wildfire response to protect forests, people, and infrastructure worldwide. The mission will deploy its latest plane of satellites called OTC-P1 to their current constellation, further expanding OroraTech’s capabilities to first responders, governments, and industry partners. The company will expand their constellation with up to 100 satellites in total by 2028.

If this launch goes as planned, expect Rocket Lab to win launch contracts for the rest of the constellation, a minimum of 11 more launches.

China launches 6th group of 18 satellites for its Spacesail internet constellation

8:52 am

China late yesterday successfully launched the sixth group of 18 satellites for its Spacesail internet constellation, its Long March 6A rocket lifting off from the Taiyuan spaceport in northeast China.

No word on where the rocket’s lower stages crashed inside China. The state-run report however touted proudly how the rocket uses liquid oxygen and kerosene, both of which are “non-toxic and pollution-free”. Apparently it has recognized the bad press it has gotten from crashing stages inside China that use very toxic hypergolic fuels.

The article noted that China plans at least ten launches in 2025 of the Long March 6A, likely as part of building this constellation of more than 1,200 satellites.

Blue Ghost completes first main mid-course correction engine burn

10:22 am

Firefly’s Blue Ghost lunar lander has not only successfully completed its first major engine burn, raising its Earth orbit as it slowly moves towards the Moon, but successfully used a joint NASA-Italian instrument to pinpoint its location using Earth-orbiting GPS-type satellites.

Jointly developed by NASA and the Italian Space Agency, the Lunar GNSS Receiver Experiment (LuGRE) technology demonstration acquired Global Navigation Satellite System (GNSS) signals, and calculated a navigation fix at nearly 52 Earth radii: more than 205,674 miles (331,000 kilometers) from Earth’s surface. This achievement suggests that Earth-based GNSS constellations can be used for navigation at nearly 90% of the distance to the Moon, an Earth-Moon signal distance record. It also demonstrates the power of using multiple GNSS constellations together, such as GPS and Galileo, to perform navigation.

These results suggest that if all lunar orbiters had this instrument on board, they could all pinpoint their positions precisely and thus eliminate the chance of collision. It also suggests that it might not be necessary, at least immediately, to build a separate GPS-type constellation around the Moon. Earth’s systems could do the job.

Blue Ghost will spend 25 days in Earth orbit, when it will transfer to lunar orbit for several more weeks before attempting a landing.

Fast radio burst unexpectedly traced to dead and old elliptical galaxy

10:12 am

Location of Fast Radio Burst
Figure 4 from this paper [pdf].

The uncertainty of science: Using several radio telescopes working in tandem, astronomers have been able to identify the source galaxy of a fast radio burst (FRB) that repeatedly erupted throughout 2024, and discovered it came from a dead and old elliptical galaxy, not a younger galaxy as predicted.

[W]hile most FRBs originate well within their galaxies, the team traced FRB 20240209A to the outskirts of its home — 130,000 lightyears from the galaxy’s center where few other stars exist. “Among the FRB population, this FRB is located the furthest from the center of its host galaxy,” said Vishwangi Shah, a graduate student at McGill, who led the effort to pinpoint the FRB’s origins. “This is both surprising and exciting, as FRBs are expected to originate inside galaxies, often in star-forming regions. The location of this FRB so far outside its host galaxy raises questions as to how such energetic events can occur in regions where no new stars are forming.”

The small ellipse to the upper left of the giant elliptical galaxy (in yellow) marks the location of the FRB relative to its galaxy. Why it is so far outside remains a puzzle. The scientists consider two options: First, that the magnetar was once inside the galaxy but was kicked out at some point, and second, it simply could be inside a globular cluster that is too small to detect at this distance, two billion light years away.

Both explanations have problems and really don’t work.

Finland signs Artemis Accords

9:50 am

Finland today became the 53rd nation to sign the Artemis Accords. Based on the official statement from Wille Rydman, Finland’s minister of economic affairs, it appears Finland sees the accords as a way to encourage its own private space sector:

“Finland has been part of the space exploration community for decades with innovations and technology produced by Finnish companies and research institutions,” said Rydman. “The signing of the Artemis Accords is in line with Finland’s newly updated space strategy that highlights the importance of international cooperation and of strengthening partnerships with the Unites States and other allies. We aim for this cooperation to open great opportunities for the Finnish space sector in the new era of space exploration and in the Artemis program.”

The NASA press release still appears to focus on strengthening the Outer Space treaty, but I suspect that this Biden-imposed goal will change now that Trump is president. The original purpose of the accords as created during Trump’s first term was to work around the Outer Space treaty’s limitations on private ownership in space. Expect a return to that goal.

The full list of nations now part of this American space alliance: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Liechtenstein, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Panama, Peru, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

South Korea’s space bureaucracy attempts to encourage private sector development

9:38 am

South Korea’s space agency, the Korea Aerospace Administration, has announced a new effort to encourage that country’s private sector in developing rockets and satellites.

[A] plan will be established to link the National Space Council, the highest policy decision-making body overseeing government space policy, with the Aerospace Development Policy Review Committee. Systems will also be established for workforce training in aerospace and the designation of a space development mission center.

To establish an aerospace economic ecosystem, the participation of the private sector in the development and utilization of launch vehicles and satellites will be expanded. In the aviation sector, future aircraft technologies, including urban air mobility (UAM), will be secured, and localization of aircraft materials and components will be supported. To encourage smooth research and development (R&D) investments in aerospace corporations, the aerospace fund will be revitalized with improvements to regulations and support for overseas expansion.

Overall, a lot of this sounds like meaningless bureaucratic gobbledygook. The goal might be to expand the private sector, but the program still has the space agency running everything, from its new government-built Nuri rocket to its other satellite development programs.

Nonetheless, the desire to encourage the private sector is good. It could simply be that South Korea’s private sector is not mature enough yet to take the lead, and the agency by this announcement is working to push it forward.

General Atomics successfully tests fuels to be used in an in-space nuclear propulsion system

9:16 am

The company General Atomics announced yesterday that it has successfully tested the fuels it wants to use in an in-space nuclear propulsion system for transporting ships to the Moon and beyond much faster and more efficiently than is presently possible with chemical engines.

[General Atomics] executed several high-impact tests at NASA’s MSFC in Huntsville, AL. The nuclear fuel was tested with hot hydrogen flow through the samples and subjected to six thermal cycles that rapidly ramped-up to a peak temperature of 2600 K (Kelvin) or 4220° Fahrenheit. Each cycle included a 20-minute hold at peak performance to demonstrate the effectiveness of shielding the fuel material from erosion and degradation by the hot hydrogen. Additional tests were performed with varying protective features to provide further data on how different material enhancements improve performance under reactor-like conditions.

It has been known since the 1960s the nuclear propulsion is more efficient that chemical engines. It can burn for longer time periods at higher levels, thus making it possible to get to other planets more quickly, in some cases bypassing the need to depend on orbital mechanics.

The problem however has been political. Getting these nuclear engines into orbit has been too much of a political hot potato. The fear of such engines and radioactivity, largely irrational, has made it impossible to get them built. NASA is now trying again.
