NASA calls for the private sector to launch VIPER to the Moon

10:55 am

As a follow-up of its August request for suggestions on how to save its cancelled VIPER rover mission to the Moon, NASA has now issued a request for actual proposals from the private sector for flying the mission, due on March 3, 2025.

The Announcement for Partnership Proposal contains proposal instructions and evaluation criteria for a new Lunar Volatiles Science Partnership. Responses are due Monday, March 3. After evaluating submissions, any selections by the agency will require respondents to submit a second, more detailed, proposal. NASA is expected to make a decision on the VIPER mission this summer.

…As part of an agreement, NASA would contribute the existing VIPER rover as-is. Potential partners would need to arrange for the integration and successful landing of the rover on the Moon, conduct a science/exploration campaign, and disseminate VIPER-generated science data. The partner may not disassemble the rover and use its instruments or parts separately from the VIPER mission. NASA’s selection approach will favor proposals that enable data from the mission’s science instruments to be shared openly with anyone who wishes to use it.

Expect a number of companies to tout their proposals in press releases in the coming weeks.

Boeing writes off another half billion dollars due to Starliner

10:02 am

In filing an annual report to the SEC, Boeing revealed that has written off another half billion dollars due to Starliner delays and technical problems, bringing the total the company has lost on the capsule to more than two billion.

In the company’s 10-K annual filing with the U.S. Securities and Exchange Commission Feb. 3, Boeing said it took $523 million in charges on Starliner in 2024. The company blamed the losses on “schedule delays and higher testing and certification costs as well as higher costs for post certification missions.”

Both Boeing and NASA remain utterly silent on the future of Starliner. It remains uncertified for operational manned flights, which means Boeing continues to earn nothing from it. Will it have to fly another manned mission on its own dime to get that certification? Or will NASA instead pay it to fly a cargo mission to ISS, as rumors have suggested, to prove the capsule is ready for manned flights?

No one knows. Nor do we know if Boeing will either sell off its space division or cancel Starliner entirely and thus free itself of the problem.

Cool image time! The panorama above was created by me from three images taken by Curiosity’s left navigation camera today (available here, here, and here).

The overview map to the right provides the context. The blue dot marks Curiosity’s present position. The red dotted line marks the planned route, while the white dotted line its actual travels. The yellow lines indicate the area covered by the panorama above.

The butte in the center where the red dotted line ends is about a half mile away. The far rim of Gale Crater is about 25 to 30 miles beyond. Though Curiosity has climbed about 3,000 feet from the floor of the crater where it landed, it still sits about 5,000 feet below the top of the crater’s rim.

As you can see, the air at Gale Crater has cleared somewhat from December 2024. Then the rim was barely visible. Now it can be seen, though the crater floor is still obscured by a layer of dust.

The journey west continues to slow but steady. The rover can only go so far each day across this very rough terrain, so as to protect its already damaged wheels.

Is SpaceX routinely stiffing its outside construction contractors in Boca Chica?

9:31 am

According to an article today in the San Antonio Express-News SpaceX has been routinely not paying its bills to construction contractors hired by it to build things in Boca Chica, and almost three dozen have had to file liens against the company to get their money.

A San Antonio Express-New review of Texas property records found at least 29 contractors — and six in San Antonio — have filed 77 liens against SpaceX since March 2022. Their total value is up from $2.5 million in May. Since then, SpaceX has settled at least six liens but gained another 44.

Though it’s unclear whether the money is owed by SpaceX, its general contractors or subcontractors, landowners are ultimately responsible for unpaid construction bills on their properties under Texas law. The liens are a legal mechanism for contractors and suppliers to secure their claims.

The article admits repeatedly that its information is incomplete, and that many of these liens might already be settled. It also admits that the failure to pay might not be by SpaceX, but as landowner with the most money, it is the biggest target capable of forcing payment by others.

It is also likely, with the amount of work and expansion that is going on at Boca Chica, such liens are somewhat expected, especially because they seem to be a relatively small amount compared to the billions that SpaceX is spending in the area.

Thus, though the article appears to suggest SpaceX is a deadbeat company, it also appears the article might also be part of the propaganda press’s effort to slander Elon Musk wherever it can.

Regardless, if SpaceX is behind in paying its bills, it needs to fix this issue now.

Satellite startup Astranis awards SpaceX another launch contract

9:17 am

The satellite startup Astranis, which already has five small satellites placed in orbit by SpaceX, has announced a new SpaceX launch contract for launching its next five satellites later this year.

By making its geosynchronous satellites small, like cubesats, the company is challenging the recent trend away from these high orbits. In the past five years very few new big geosynchronous communications satellites have been built or launched, because they can’t compete with the cheaper low-orbit smallsats.

Astranis is bucking that trend, partly because of its small satellites, and partly because SpaceX’s launch costs are so much less than anyone else’s.

British rocket start-up Orbex wins two-launch contract from Italian orbital tug company D-Orbit

9:10 am

The British rocket start-up Orbex, which hopes to complete its first test orbital launch of its Prime rocket this year, after years of regulatory delays, has gotten a two-launch contract from the Italian orbital tug company D-Orbit.

The contract appears to be part of Europe’s effort to have its European payloads launch on European rockets. Previously D-Orbit tugs have mostly been launched by SpaceX because the only available European rockets, Ariane-6 and Vega-C, have either not been operational or available. Moreover, all these rockets are too big for D-Orbit’s tugs, which thus have to fly as secondary payloads.

Orbex’s Prime rocket is small, and so the tugs can be launched as the primary payload. The rocket however is not yet operational, unlike for example Rocket Lab’s small Electron rocket. The decision to go with Orbex’s untested rocket suggests Europe is forcing D-Orbit to sign with a European rocket company.

OneWeb is years behind schedule in activating its service in the Falklands

8:59 am

Despite contracts with the local government that said service would begin in 2023, OneWeb has still not activated its service in the Falklands, and that government is considering switching to Starlink as it considers legal action to recover its money.

Local reports say that the Falkland Islands government “wants its money back” from an agreement which it entered into with local telco SURE and which provides national and international fixed line, mobile data and broadband services as well as data centre and enterprise solutions to consumer and corporate customers. SURE is part of Bahrain’s Batelco Group and SURE’s coverage extends to the Ascension Islands and Saint Helena in the South Atlantic.

The problem is seemingly OneWeb. Mark Pollard, a member of the Falkland’s Legislative Assembly, speaking on January 30th, said that the telco had failed to introduce a promised service from OneWeb, which itself was supplied with capacity from Eutelsat and prime contractor Intelsat.

The article at the link does not provide any explanation for the delay. It is probably related to OneWeb’s requirement for ground stations to connect the local communications network with the satellites. There must be issues building those ground stations. Starlink meanwhile provides antennas to customers which connect directly to the satellites.

The article also notes the company’s stock value has been plummeting, dropping 62% in the past six months.

Indian navigation satellite stranded in wrong orbit

8:49 am

Though the GSLV launch rocket worked as planned, putting India’s new navigation satellite in the proper transfer orbit on January 29, 2025, the satellite’s own engines have failed to fire.

Subsequent to the launch, the solar panels on board the satellite were successfully deployed and power generation is nominal. Communication with the ground station has been established. But the orbit raising operations towards positioning the satellite to the designated orbital slot could not be carried out as the valves for admitting the oxidizer to fire the thrusters for orbit raising did not open.

The satellite systems are healthy and the satellite is currently in elliptical orbit. Alternate mission strategies for utilising the satellite for navigation in an elliptical orbit is being worked out. [emphasis mine]

The highlighted sentence suggest India’s space agency ISRO has determined there is no way to raise the orbit to its proper height. With the solar panels deployed and the spacecraft’s orbit having low point that dips into the Earth’s atmosphere, the satellite’s orbit will likely decay relatively quickly. If so, the satellite’s mission will be a failure, not a good way to start what ISRO’s hopes to be its busiest year.

Japan’s H3 rocket successfully completes its fifth launch

9:40 am

Japan’s space agency JAXA early today successfully launched the sixth satellite in that country’s GPS-type constellation, its new H3 rocket lifting off from the Tanegashema spaceport in south Japan.

This was the rocket’s fifth launch, and the first for Japan this year. The link goes to the JAXA live stream, cued to T-30 seconds. Though it now also provides English translation, JAXA still insists on having an announcer count off every second, several minutes prior to and after launch, something that is incredibly annoying and distracting, and entirely unnecessary.

14 SpaceX
6 China
1 Blue Origin

Hardened dunes or eroded lava?

hardened dunes or eroded lava?
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 4, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is labeled as a “terrain sample,” so it likely was taken not as part of any specific research project but to fill a gap in the schedule in order to maintain the camera’s proper temperature.

The picture shows a flat rippled plain with a handful of very small thin ridges, oriented 90 degrees from the smaller ripples and sticking up a few feet above them.

The rough surface of the small ripples suggest these are dunes of sand that have hardened into rock. The thin larger ridges suggest an underlying topography buried by the sand. The dunes however might not be dunes at all, as indicated by their location.

SpaceX and Vast jointly request research proposals for first mission to Vast’s Haven-1 space station

10:39 am

With the launch of Vast’s single module space station Haven-1 still scheduled for August, SpaceX and Vast have jointly requested research proposals (here and here) for station’s first manned mission, expected to be a four person 30-day flight soon thereafter. From the Vast press release:

Building on their established partnership, the two companies seek high-impact research projects to support humanity on Earth and advance our capacity to live and work in Earth orbit and beyond. Submitted proposals will be evaluated based on scientific and technical merit, feasibility, and alignment with mission objectives. Approved research proposals will be able to leverage the capabilities of the Haven-1 Lab, Dragon spacecraft, and/or private astronaut missions to the International Space Station (ISS).

Haven-1 is the only one of four commercial space stations being designed or built that has taken no NASA money. It also appears it will be the first to launch, thus putting it an excellent position to win the larger space station contract from NASA to build its much larger Haven-2 station.

Though neither SpaceX nor Vast are offering any funding for these proposals, they offer researchers access to space quickly and with relatively little bureaucracy (something all scientists routinely face in working with NASA). Researchers who fly on that first mission will also become well positioned to win further NASA research space station contracts later on.

NASA’s useless safety panel makes another useless announcement about Starliner

10:15 am

An official of NASA’s ineffectual and largely corrupt safety panel yesterday made another meaningless update on the work Boeing is doing to fix the thruster problems that occurred on the first manned flight of its Starliner manned capsule last summer, and as always told us absolutely nothing.

Paul Hill, a member of the Aerospace Safety Advisory Panel (ASAP), said at a Jan. 30 public meeting that the committee was briefed on the status of the investigation into Starliner’s Crew Flight Test (CFT) mission recently. That mission launched in June with NASA astronauts Butch Wilmore and Suni Williams on board, but the spacecraft returned to Earth three months later uncrewed because of agency concerns about the performance of spacecraft thrusters.

“NASA reported that significant progress is being made regarding Starliner CFT’s post-flight activities,” he said. “Integrated NASA-Boeing teams have begun closing out flight observations and in-flight anomalies.” He didn’t elaborate on the specific issues that the teams had closed out but stated that it did not include the thrusters, several of which shut down during the spacecraft’s approach to the station. The propulsion system also suffered several helium leaks. [emphasis mine]

In other words, this announcement was meaningless, because it included no information about the main problem. Hill’s comments were mostly empty blather, which is generally what this panel says in all its announcements. We still do not know when or if Starliner will fly again with astronauts on board.

Over the years the panel has bent over backwards to say positive things about Boeing, so that it missed all of Boeing’s design and construction failures from day one. At the same time it repeatedly slammed SpaceX, even though that company clearly had its act together and ended up fulfilling all of its contract obligations to NASA, even as Boeing has failed to do so.

If I was a member of Trump’s DOGE project, eliminating this safety panel would be very high on my list of things to do to make NASA’s more efficient. All it does is slow things down, often for exactly the wrong reasons.

Malaysia begins spaceport study

9:56 am

Malaysia
Click for original image.

The Malaysian state of Sabah this week announced it has partnered with a Ukrainian government agency to study the possibilities of developing its space industry, including establishing a spaceport on that state’s coast.

Initially floated in 2023, the state government signed a memorandum of understanding with Ukraine’s Yuzhnoye State Design Office – which specialises in space-rocket technology – and local defence and aerospace firm Sovereign Sengalang, to explore Sabah’s potential as a regional space launch site.

Sabah has an extensive shoreline stretching about 1,500km on its mainland, and sits close to the equator, ideal conditions for rocket launches and recovery.

Based on the map to the right, it seems the best location for a Sabah spaceport would be on the state’s eastern coast, to the south. Any other location means rockets would have to cross land or islands of other nations.

Ispace posts first picture taken by its Resilience lunar lander

9:30 am

Map of lunar landing sites
Landing sites for both Firefly’s Blue Ghost and
Ispace’s Resilience

The Japanese startup Ispace on January 29, 2025 released the first picture taken by its Resilience lunar lander, a series of images of Earth.

More important, the company reported that the spacecraft is “in excellent health.”

Though launched on the same rocket with Firefly’s Blue Ghost lunar lander, Resilience is taking a longer route to the Moon. Blue Ghost plans to land on the Moon in about six weeks. Resilience won’t get there for about four more months. Both are using the same technique, slowly over time raising the spacecraft’s Earth orbit until its high point enters the Moon gravitational sphere of influence, where each will transfer to lunar orbit. This method saves weight and fuel, as it requires a smaller rocket engine to make the trip. That Resilience is taking longer is simply because it uses an even smaller engine that can only raise that orbit in smaller increments.

The crew and passengers for Axiom’s fourth tourist flight to ISS

9:19 am

Axiom this week publicly introduced the international crew and passengers for its fourth tourist flight to ISS, presently planned for this spring.

During a Thursday press conference, former NASA astronaut and Axiom commander Peggy Whitson introduced her team. Shubhanshu Shukla will pilot the fourth mission to the ISS. He has been a fighter pilot for 15 years and will be the first Indian pilot to travel to the ISS.

The private mission also carries the first astronauts from Poland and Hungary to stay aboard the space station. Sławosz Uznański-Wiśniewski is an ESA astronaut representing Poland. Tibor Kapu is a mechanical engineer who was selected as an astronaut for Hungary’s Hungarian to Orbit (HUNOR) program in May of last year.

Axiom had made deals with India, Poland, and Hungary years ago to fly astronauts in space, and this flight fulfills those deals. Launched on SpaceX’s Falcon 9 rocket, their Dragon capsule will spend 14 days in space, most of which will be docked to ISS.

A big crack on Mars

A big crack on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 1, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label “a fracture with clays.”

This canyon is about a mile and a half wide, with the floor ranging from 800 to 1,100 feet to the rim. It was not formed initially by any ice or water flow, but by a spreading of the crust, forcing cracks to form that might have later been modified by wind, ice, or water. The presence of clays in this canyon strengthens that later ice/water modification, as clays require water to form.

The streaks on the northern wall are slope streaks, an unexplained phenomenon unique to Mars. While at first glance they look like avalanches, they have no debris piles at their base, and do nothing to change the topography. In fact, streaks can sometimes go uphill for short distances, following the surface. They happen randomly throughout the year, and fade with time.

It is believed their cause is related to dust avalanches, but this is only one of a number of theories that attempt to explain them. None is entirely satisfactory.

Samples from the asteroid Bennu reshape entirely our understanding of the solar system’s early make-up

11:11 am

superimposed for scale. Click for full image.

First, I hope my readers will notice that — unlike NASA and the entire press — I make no mention in my headline above of the discovery of a “mix of life’s ingredients” or “the key building blocks of life” from the samples brought back by the probe OSIRIS-REx from the asteroid Bennu.

This is the game NASA does all the time, to hint at the discovery of life when this is not the real discovery. NASA does it because it knows that if you hint at such a discovery, the press will go crazy and give you lots of press.

The real news from the two papers published this week, available here and here, however, is more fundamental. Before the samples from Bennu and Ryugu (brought back by the Japanese probe Hayabusa-2) had arrived, our understanding of the make-up and chemistry of the early solar system was very incomplete and badly biased. The only asteroid samples we had of carbonaceous chondrite asteroids, the most primitive and fragile carbon-rich asteroids in the solar system, had came from meteorites that had survived the journey through the Earth’s atmosphere. Thus, the only material that survived was robust enough to do so. The more fragile molecules however were always destroyed and thus missing from meteorites, even though it was very clear from spectroscopy of these asteroids in the solar system that such molecules did exist, and likely formed the majority of these asteroids’ make-up.

Thus, though carbonaceous chondrite asteroids represent the early solar system, our understanding of them was warped and very incomplete. The whole point of both missions to Bennu and Ryugu was to fill in this data, to get a more complete census of the real make-up of the early solar system.

The two papers published this week have given us that. That’s their real discovery.

Update on upcoming Starship/Superheavy test flights

9:23 am

Link here. As usual, this NASASpaceflight.com article provides an excellent overview of what SpaceX is likely to do on the next few test flights, including details about the possibility of reusing the Superheavy that was successfully recovered on the seventh flight.

And as usual, NASASpaceflight.com ignores the importance of politics and Trump’s election in changing the regulatory culture at the FAA. Just as it has made believe the Biden administration wasn’t forcing the FAA to slow-walk its license approvals to SpaceX, it is now making believe the Trump administration won’t do anything to force the FAA to speed its approvals.

We know however that it will. I fully expect that when SpaceX completes its investigation of the failures from flight 7 and describes its fixes, the FAA approval will following very quickly thereafter, within days. Under Biden that approval would still take months.

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.

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.

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.

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.
