Europe’s Juice probe to Jupiter yesterday successfully completed its close fly-by of the Moon, shifting its path as it prepares for a close fly-by of the Earth today.

The picture to the right, cropped, reduced, and sharpened to post here, was taken during yesterday’s flyby. At its closest approach Juice was only 435 miles above the lunar surface. It will pass the Earth today at a distance of 4,230 miles.

If the Earth fly-by today is successful, Juice will then do flybys of Venus in August 2025, Earth in September 2026, and Earth again in January 2029, arriving in Jupiter orbit in July 2031, where it is designed to study the large icy moons (Europa, Gandymede, and Calisto) of that gas giant.

SpaceX gets FCC okay for next Starship/Superheavy test flight

9:41 am

The FCC yesterday issued SpaceX a communications license for the fifth orbital test launch of its giant Starship/Superheavy rocket, with the license permitting Superheavy to “either return to the launch site or perform a controlled water landing.”

The license runs through February 15, 2025.

This does not mean a launch has been approved however. The FCC only gives approval for radio communications on such a flight. It is the FAA that must issue the actual launch license, and it as yet not done so.

SpaceX had announced on August 8, 2024 that it was ready to go. It is now almost two weks since then and the FAA has said nothing.

The only justifiable reason for this delay would be that SpaceX has requested permission to do the first chopstick landing of Superheavy at Boca Chica (as suggested by the FCC approval), and since this changes the already approved flight path from the previous four test launches, the FAA is reviewing it more closely, and taking its time to do so.

The simple fact is that it can’t learn anything by this review. It isn’t qualified to make any educated determination. Either it is willing to let SpaceX do that return, or not. If it is against it at this point, it should simply say so, demand SpaceX hold off a chopstick landing until later, and give it permission now to do another ocean landing. At least this way the company would have clarity and could proceed.

Rocket Factory Augsburg’s rocket fails during 9-engine static fire test

9:21 am

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

During a static test yesterday of Rocket Factory Augsburg’s RFA-1 rocket, the first using all nine first stage engines, the rocket experienced what the company called an “anomaly” early in the test, causing a major fire and explosion.

The company’s statement also said the launchpad was “saved” and no one was injured.

I have embedded below a clip from a BBC video of the event. A company official had said only yesterday that it hoped to launch in a matter of weeks, though that official had given no word on whether the UK’s Civil Aviation Authority (CAA) had issued a launch license. I suspect he hoped this test would be successful and the CAA would then issue the license. That won’t happen now.

The test took place at the new commercial Saxavord spaceport in the Shetland Islands, which has also struggled in the past two years to get full licensing from the CAA. It has obtained those licenses, but it would not be surprising if this failure will cause the CAA — which appears very risk adverse — to reconsider its approvals.

Until this failure, Rocket Factory appeared to be in the lead among the new European rocket startups to complete its first launch. That now changes. The Spanish startup PLD hopes to launch from French Guiana in 2025, and is presently building its launchpad there. The UK startup Orbex also hopes to launch in 2025, but it wants to launch from the Sutherland spaceport in Scotland, has faced significant regulatory delays over the past two years from the CAA, and will now likely face further delays because of this failure. Another German startup, Hyimpulse, has already completed a suborbital test launch from Australia, but has not set a date for an orbital test. It originally hoped to launch from Saxavord in 2025, but has been looking for alternatives recently. Finally, the German startup Isar Aerospace has a deal to launch from the Andoya spaceport in Norway, but has announced no launch date.

SpaceX launches 20 more Starlink satellites using a new first stage

8:50 am

SpaceX early this morning successfully launched another 20 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage was new, having never flown before. It successfully landed on a drone ship in the Atlantic, and is now part of the company’s fleet of Falcon 9 first stages.

The leaders in the 2024 launch race:

83 SpaceX
34 China
10 Rocket Lab
9 Russia

American private enterprise now leads the rest of the world combined in successful launches 98 to 52, while SpaceX by itself now leads the entire world combined, including American companies, 83 to 67.

Mining Mars

Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 22, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The picture’s focus of study is the bright strip running diagonally across the center, which the scientists label as a “linear feature exposure of infrared-bright material.”

This bright strip with all the swirls of alternating light and dark terrain is a fissure about 80 feet deep. What is interesting is that the parallel bright features to the north and south are actually ridges, not depressions, even though there appears to be some resemblance between them all. (Note that the patches of very thin parallel lines are likely ripple dunes sitting on top of the topography.)

So, what created this fissure? And why is its inner surface so strange? As is usually the case, a wider look provides some clues.

Sierra Space in negotiations to buy ULA

10:26 pm

According to the Reuters news agency, Sierra Space is negotiating with the joint owners of ULA, Boeing and Lockheed Martin, to buy the rocket company.

The sources, which are all anonymous, said the sale price is in the range of $2 to $3 billion. Those same sources said no deal has yet been worked out, and might not happen at all.

For Sierra, the deal would give it its own launch vehicle, Vulcan, for placing its Dream Chaser mini-shuttles into orbit. It would also give it a profit stream from the many military and commercial launch contracts already on ULA’s manifest. The combined cababilities of ULA and Sierra will create a formidable new player in the aerospace launch market.

For Boeing, it would provide it some much needed cash that it will be able to use to both restructure and revitalize its presently questionable operations.

It is unclear what Lockheed Martin will gain from the sale, other than the cash and the removal of this Frankenstein-like partnership with Boeing, which in the long run has probably not done it a lot of good.

SpaceX launches 116 payloads on its eleventh smallsat Transporter mission

12:20 pm

SpaceX today successfully launched 116 payloads, including 108 satellites, on its eleventh smallsat Transporter mission, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its twelfth flight, landing back at Vandenberg. As of posting the satellites had not deployed.

The payloads included a wide variety of satellites and demonstration missions, including one orbital tug from the European tug company D-Orbit, its Ion tug deploying five satellites. In addition, five different companies will be using their own deployment equipment to release about fifty of the satellites from the Falcon 9.

These SpaceX Transporter smallsat launches demonstrate the value of lowering the cost to launch. Almost none of these satellites could have obtained investment capital when the cost high. Now that SpaceX has lowered that cost, a plethora of new satellite companies of all kinds can get that capital and build and launch their projects. And that burst of new companies is more than enough to provide business not only to SpaceX but to a lot of other new rocket startups.

The leaders in the 2024 launch race:

82 SpaceX
34 China
10 Rocket Lab
9 Russia

American private enterprise now leads the rest of the world combined in successful launches 97 to 52, while SpaceX by itself still leads the entire world combined, including American companies, 82 to 67.

Martian gullies flowing down to a Martian river of ice

11:30 am

Gullies on cliff wall
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 16, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this as “gullies previously identified in the walls of Harmakhis Vallis.” The gullies are obvious, the series of erosion features on the cliff wall. The cliff itself drops about 2,800 feet from the rim to the floor, and also appears to have internal horizontal layers that the gullies cut through.

What causes the gullies? Planetary scientists have a number of theories, none of which appear to explain the gullies everywhere on the Martian surface. They all appear in the mid-latitudes, where the most glaciers on Mars are found, and appear to be related to ice or frost freeze-thaw processes, with some gullies actually very ancient and formed when the planet’s rotational tilt was significantly different.

New data continues to refine the margin of error for the Hubble constant

9:45 am

The uncertainty of science: New data using the Webb Space Telescope’s spectroscopic capabilities has provided a more refined measure of the expansion rate of the universe, dubbed the Hubble constant.

According to previous research, that rate could be anywhere from 67.4 to 73.2 kilometers per second per megaparsecs, depending on whether you rely on data from the Planck orbiter or that of the Hubble Space Telescope. Though this difference appears reasonable considering the uncertainties and assumptions that go into research that determines both numbers, astronomers have been unhappy with the difference. The numbers should match and they don’t.

Now new data from Webb suggests this difference really is nothing more than the margin of error caused by the many uncertainties and assumptions involved. That new Webb data measured the Hubble constant using three different methods, all similar to that used by Hubble, and came up with 67.85, 67.96, and 72.04, all in the middle of the previous two numbers from Hubble and Planck.

In other words, all the data is beginning to fall within this margin of error.

Astronomers are without doubt still going to argue about this, but it does appear that the research is beginning to coalesce around an approximate number. More important, in terms of cosmology these results confirm the theory that the expansion of the universe is accelerating (dubbed “dark energy” simply because it needs a name), since they confirm the method used to measure that expansion rate in the very distant universe.

Keep your minds open however. There remain many questions and uncertainties with all these conclusions. Nothing is settled, nor will it be likely for decades if not centuries.

China launches new set of classified remote-sensing satellites

9:06 am

China today launched a new set of classified remote-sensing satellites supposedly designed to test “new technologies of low-orbit constellations, using its Long March 4B rocket lifting off from its Xichang spaceport in the southwest of China.

Almost no information was released about the satellites. Nor did China’s state-run press reveal where the rocket’s lower stages, carrying toxic hypergolic fuels, crashed within China.

The leaders in the 2024 launch race:

81 SpaceX
34 China
10 Rocket Lab
9 Russia

American private enterprise still leads the rest of the world combined in successful launches 96 to 52, while SpaceX by itself still leads the entire world combined, including American companies, 81 to 67.

These numbers will likely change in only a few hours, as SpaceX has another launch today, scheduled for 11:20 am (Pacific).

NASA reconsiders cancellation of overbudget and behind schedule robotic refueling mission

8:59 am

Due to some pressure from Congress (which wants the 450 jobs the project employs), NASA is now reconsidering its cancellation of the On-Orbit Servicing, Assembly and Manufacturing (OSAM) 1 mission, designed in the late 2000s to demonstrate the robotic refueling of a dead satellite but is so overbudget and behind schedule that in the interim private enterprise accomplished the same goal now repeatedly for a fraction of the cost.

Language in the final fiscal year 2024 appropriations bill, released just days after NASA’s cancelation announcement, which fully funded OSAM-1 at $227 million, directed NASA to adjust the mission to launch in 2026 within the spending profile NASA included in its 2024 budget request. That could be done, the report accompanying the bill suggested, through “potential de-scoping of some non-essential capabilities,” adding that if it is not possible, NASA should conduct another continuation review in September.

In other words, Congress wants NASA to keep this project, even if it means cutting the budget of other more useful and valuable missions.

OSAM has cost a billion dollars so far, and after almost fifteen years has not yet flown. Meanwhile, Northrop Grumman’s MEV servicing robot has already provided fuel to several dead satellites, while orbital tug startups are flying missions and developing the same refueling capabilities for far less. The industry doesn’t need this demonstration mission anymore. It has already demonstrated it, and done so better.

Moreover, why the heck does OSAM require 450 people? That number is absurd, and likely exceeds the payrolls of all the orbital tug companies plus Northrop’s robotic servicing division combined.

There is hope for the American taxpayer. The legislative recommendations above come solely from the Senate. The House appears less interested in spending this money. And NASA has not yet decided what it will do.

India completes third and last test launch of its SSLV rocket

8:57 pm

India today successfully completed the third and last test launch of its Small Satellite Launch Vehicle (SSLV), lifting off from its Sriharikota spaceport and carrying an experimental satellite designed to test a number of new technologies.

This launch is three-plus years late. It was originally to take place no later than 2021, but India’s space agency ISRO shut down entirely during the COVID panic, putting a halt on the rocket’s development. This delay also badly damaged ISRO’s attempt to grab the smallsat launch market. While it hid in basements in fear of a virus comparable to the flu, companies on the U.S. pushed to grab that market. Whether it can now grab its own market share is unclear, but the increased regulatory burdens that have appeared in the U.S. in the last three years gives it an opportunity.

This was India’s third launch in 2024, so the leader board in the 2024 launch race remains unchanged:

81 SpaceX
33 China
10 Rocket Lab
9 Russia

American private enterprise still leads the rest of the world combined in successful launches 96 to 51, while SpaceX by itself still leads the entire world combined, including American companies, 81 to 66.

Lockheed Martin to purchase satellite builder Terran Orbital

1:48 pm

Lockheed Martin today announced that it intends to purchase the satellite company Terran Orbital, of which it already owns one third of its stock.

Lockheed said Aug. 15 it would buy Terran Orbital for $0.25 per share in cash and retire the company’s existing debt. The deal, expected to close in the fourth quarter, has an enterprise value of $450 million. Shares in Terran Orbital closed Aug. 14 at $0.40.

Lockheed had six months ago offered to buy the company for $1 per share, but then withdrew the offer. It appears this new offer is intended to save the company, as Lockheed needs it. Right now 90% of Terran Orbital’s contracts are with Lockheed, and if the company goes under so do those deals.

This situation appears related to funding problems being experienced by the Rivada 300-satellite constellation. It had signed a $2.4 billion contract with Terran to build those satellites, but Terran removed that contract from its listed deals this week, suggesting that it no longer expected it to happen.

Lockheed Martin has made a strong effort in the past decade to remake itself to meet the challenges of the new space market, including entering the smallsat satellite manufacturing market. Thus it should be able to absorb Terran Orbital’s operations with little major harm to both, and much benefit.

Hat tip to BtB’s stringer Jay.

A tour of Blue Origin’s New Glenn factory

1:33 pm

Tim Dodd of Everyday Astronaut on May 30, 2024 was given a detailed tour by founder/owner Jeff Bezos of Blue Origin’s New Glenn factory at Cape Canaveral.

It is incredible to watch, because for the very first time, Bezos shows us what the company is finally doing to prepare for the first New Glenn launch, targeting no earlier than the end of September. Unlike every other visual shown of this facility in the past, this tour actually shows a factory floor where work is going on.

Much of the backgrounds inside the stages have apparently been put out of focus to protect Blue Origin’s proprietary rights. No matter.

As for the state of the manufacture of the BE-4 engines, Bezos stated that he expects next year to be building one engine every three days. Cross your fingers that he is right.

I have embedded the video of the tour below. Enjoy, and get excited by the competition and capability this rocket will create when it finally starts flying.

Astronomers discover a nearby star moving so fast it could even escape the Milky Way

10:20 am

Astronomers, both professional and amateur, have discovered a nearby star only 400 light years away that is moving so fast, 1.3 million miles per hour (almost three times faster than the Sun), it might very well escape the Milky Way and fly into intergalactic space in the far future.

The star, named CWISE J124909+362116.0 (or “J1249+36” for short), was first spotted by some of the over 80,000 citizen science volunteers participating in the Backyard Worlds: Planet 9 project, who comb through enormous reams of data collected over the past 14 years by NASA’s Wide-field Infrared Survey Explorer (WISE) mission. This project capitalizes on the keen ability of humans, who are evolutionarily programmed to look for patterns and spot anomalies in a way that is unmatched by computer technology. Volunteers tag moving objects in data files and when enough volunteers tag the same object, astronomers investigate.

J1249+36 immediately stood out because it was moving at about .1 percent the speed of light.

The star itself is either a very low mass red dwarf, or possibly a brown dwarf that never quite had enough mass to ignite as a star.

You can read the research paper here [pdf]. The researchers posit two possible explanations for the star’s speed. Either it was once part of a binary and thrown out when its white dwarf companion exploded as a supernova, or was once located in a densely packed globular cluster, where the interaction with other stars or even black holes could have flung it away.

Rocket startup Stoke Space is saddled with the same red tape as SpaceX

10:06 am

Stoke's Nova rocket
Stoke’s Nova rocket

We’re from the government and we’re here to help you! The rocket startup Stoke Space appears to be struggling with the same kind of environmental red tape that is hindering SpaceX, though in Stoke’s case the red tape appears absurdly unnecessary.

Stoke is the only company besides SpaceX developing a rocket with both its first and second stages returning to Earth to land vertically and then be reused. Unlike SpaceX Starship/Superheavy, which is gigantic and revolutionary in all ways, Stoke’s Nova rocket is comparable in size to the hundreds of rockets that have launched from Florida since the 1960s. Based on that six-decade track record, it would seem that getting rights to launch Nova (but not for its return) would be considered basic and routine, requiring little complex bureaucracy.

Hah! Fooled you!

Before any of this can take place, the Space Force must complete its “environmental assessment” of the company’s plans at LC-14 [the launchpad used for John Glenn’s first orbital mission and many others subsequently], in order to evaluate how repeat launches will affect local flora and fauna. These assessments are mandatory under federal law, and they can often take months — but the upside is that they provide a closer look at a company’s operational plans.

ULA losing launch crews to other rocket companies

9:23 am

ULA, which hopes to set a company launch record next year, is right now suffering a major loss of its launch crews to SpaceX and Blue Origin.

This year alone, ULA has lost about 45 of its 105 Launch Operations engineers — the people who test, assemble and prepare every rocket and its cargo to fly — at its primary launch site in Florida, according to the person, who asked not to be identified discussing non-public information. The lack of experienced personnel has postponed work for future missions, the person said.

The article says the loss of these launch crew employees is because of higher pay offered by the other companies, but I suspect a contributing factor is ULA’s low rate of launches in recent years (3 in 2023 and 4 so far in 2024). These people have nothing to do, and see the lack of work as detrimental to their future careers. Better to move on, either to SpaceX where a lot of launches occur, one almost every other day, or to Blue Origin, where the rocket is new and the company has plenty of cash.

The flight of crews could also be because people do not see a future at ULA. For almost a year there have been rumors that Boeing and Lockheed Martin, which own it jointly, want to sell it. It was thought that sale would happen after the first Vulcan rocket launch, but it did not. In recent months those rumors have subsided, suggesting that the interest in buying the company has trailed off.

Despite these problems, ULA’s problems could very well be temporary. Its manifest has a lot of launches scheduled, and once Vulcan is certified for the military and operational for all its customers, it is expected to be launching more than twice a month next year. If those launches take place as planned, these issues will be begin to vanish very quickly.

In fact, it does appear that if you are an engineering student with an interest in rocketry, your future is extremely bright. There will be plenty of work opportunities for you in Florida in the future, from any one these companies.

NASA leaning now to send Starliner astronauts home on Dragon, in February 2025

11:01 am

Though a decision will not be made until next week, during a press briefing today the nature of the briefing and the wording by NASA officials suggested that they are now leaning strongly to having the two Starliner astronauts, Butch Wilmore and Suni Williams, return on the next Dragon capsule to launch to the station on September 24, 2024 and return in February 2025.

My conclusion is based on several subtle things. First, no Boeing official participated, the second time in row that they were excluded. Second, this briefing included some new individuals who rank higher in the chain of command, and whose opening statements were clearly written carefully in advance and were read aloud.

Third, and most important, the wording of those statements repeatedly indicated they are looking at Dragon return more seriously. For example, NASA’s chief astronaut Joe Acaba suggested strongly that the two astronauts were now well prepared for an eight month mission, rather than coming home in August 2024. Other statements by officials suggested they themselves are less confident about returning on Starliner. Though the data suggests they can return safely, there remains enough uncertainty to make some people uncomfortable.

One factor not stated but is certainly controlling the situation now is the upcoming election in November. The Democrats who control Washington and the White House will allow nothing to happen that could hurt their election chances. We must therefore assume people in the White House are now in control and are the ones who now intend to make the decision about Starliner’s return.

Based on these factors, we should expect NASA to announce next week that the crew will return in a Dragon capsule. In order for the return to happen on Starliner NASA and Boeing engineers must somehow convince those politicos that the return would be entirely safe. Since these politicos are always risk adverse, it would shock me if they can be convinced. It could happen, but understanding the politically framework is important.

The officials stated that they have scheduled the final review next week, and it appears the decision will be announced then.

The future route of Perseverance out of Jezero Crater

10:01 am

Perseverance's future route
Click for original image.

The science team for the Mars rover Perseverance today outlined the planned route they intend to follow to bring the rover out of Jezero Crater.

The map to the right shows that route in red, with the rover presently at the upper right. Though Perseverance presently sits inside Neretva Vallis, which is the channel that cuts through the rim of the crater through which poured the delta material the rover has been sampling since landing, the route out of the crater will instead head south and west, crossing over the rim.

NASA’s Perseverance Mars rover will soon begin a monthslong ascent up the western rim of Jezero Crater that is likely to include some of the steepest and most challenging terrain the rover has encountered to date. Scheduled to start the week of Aug. 19, the climb will mark the kickoff of the mission’s new science campaign — its fifth since the rover landed in the crater on Feb. 18, 2021.

…Two of the priority regions the science team wants to study at the top of the crater are nicknamed “Pico Turquino” and “Witch Hazel Hill.” Imagery from NASA’s Mars orbiters indicates that Pico Turquino contains ancient fractures that may have been caused by hydrothermal activity in the distant past.
Rover looking back at the “Bright Angel” area

Orbital views of Witch Hazel show layered materials that likely date from a time when Mars had a very different climate than today. Those views have revealed light-toned bedrock similar to what was found at “Bright Angel,” the area where Perseverance recently discovered and sampled the “Cheyava Falls” rock, which exhibits chemical signatures and structures that could possibly have been formed by life billions of years ago when the area contained running water.

For Perseverance’s recent travels, go here.

Webb data suggests the possibility of ice and hydrated minerals on surface of Psyche

9:33 am

Using the Webb Space Telescope, astronomers have detected evidence of hydrated minerals and even possibly a very tiny amount of water ice on the surface of the metal asteroid Psyche.

The Webb data point to hydroxyl and perhaps water on Psyche’s surface. The hydrated minerals could result from external sources, including impactors. If the hydration is native or endogenous, then Psyche may have a different evolutionary history than current models suggest. “Asteroids are leftovers from the planetary formation process, so their compositions vary depending on where they formed in the solar nebula,” said SwRI’s Dr. Anicia Arredondo, another co-author. “Hydration that is endogenous could suggest that Psyche is not the remnant core of a protoplanet. Instead, it could suggest that Psyche originated beyond the ‘snow line,’ the minimum distance from the Sun where protoplanetary disc temperatures are low enough for volatile compounds to condense into solids, before migrating to the outer main belt.”

However, the paper found the variability in the strength of the hydration features across the observations implies a heterogeneous distribution of hydrated minerals. This variability suggests a complex surface history that could be explained by impacts from carbonaceous chondrite asteroids thought to be very hydrated.

You can read the research paper here [pdf]. The actual amount of water possible is at most 39 parts per million and is also an order of magnitude lower than that found on the Moon, which strongly suggests that it comes from outside sources, such as impacts from other asteroids, not from the inherent geological history of Psyche itself.

The uncertainties of this research, which are large, which should be resolved when the probe Psyche, launched last year, reaches the asteroid Psyche in August 2029.

Update on status of Blue Origin’s New Glenn rocket

9:23 am

Link here. The report provides a lot of detail about the ramped up operations of Blue Origin in Florida in preparation for the first launch of New Glenn, previously announced as September 29, 2024. It appears the company is finally getting something done, and is getting closer to that launch.

Nonetheless, this detailed report makes no mention of that launch date. Furthermore, based on the work presently being done, it appears that launching by that date is impossible. With less than two months to go, the rocket has not yet been stacked and brought to the launchpad for even one dress rehearsal countdown. In March the company did tanking tests using an engineering test prototype, but so far such tests have not been done on the actual flightworthy rocket. It seems there will not be enough time to do them and meet that September 29th date.

The report also claims that Blue Origin “continues to ramp up testing its BE-4 and BE-3U engines” and “should have no problem supporting engine demand for both New Glenn and Vulcan,” but provides no hint as to the actual number of engines produced. Recent numbers suggest that ULA will have sufficient engines to launch its rockets, but will New Glenn, which needs seven BE-4 engines compared to the two needed for ULA’s Vulcan? We presently have no idea.

All in all, however, things at Blue Origin in 2024 appear to finally be happening, after a five year lull of nothing under the previous CEO, Bob Smith. Even if that launch doesn’t happen in September, it appears that it will happen sometime within the six months that follow.

Intuitive Machines wants to land VIPER rover on Moon

9:04 am

VIPER's planned route on the Moon
VIPER’s now canceled planned route at the Moon’s south pole

The lunar lander startup Intuitive Machines has now revealed it is putting together an industry partnership to bid on flying NASA’s VIPER lunar rover on its own largest lander, still under development.

In an Aug. 13 earnings call about its second quarter financial results, Intuitive Machines executives said they were planning to respond to a request for information (RFI) that NASA issued Aug. 9 seeking input from companies and organizations interested in taking over the Volatiles Investigating Polar Exploration Rover (VIPER) mission that the agency said in July it would cancel.

Steve Altemus, chief executive of Intuitive Machines, said on the call that his company, which also responded to an earlier call for “expressions of interest” from NASA regarding VIPER, is working with other companies, universities and international partners on responding to NASA’s RFI. He did not identify any of those prospective partners.

…NASA, in its RFI, said that prospective partners would be responsible for the costs of any final testing and other work on the rover itself, as well as delivering it to the lunar surface and operating it once there. NASA, in its July 17 announcement that it would cancel VIPER, said the agency would save at least $84 million by halting work now on the rover, now complete and undergoing environmental testing.

Whether this company can raise the capital to finish this mission, now that NASA has said it cannot, remains unclear. That it is trying, and NASA is not, illustrates however why NASA should get out of the business of building anything and just buy it from the private sector. NASA’s attempt to build VIPER went 3Xs over budget and is considerably behind schedule. Now the private sector see profits in finishing the job, which will in turn save the agency considerable money. Imagine if NASA had done this from the beginning. The savings would have been even greater, and VIPER might right now be even closer to launch.

Buried peaks in a sea of Martian sand

Buried peaks in a sea of sand
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on April 13, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the MRO science team labels as “streamlined features”, though that doesn’t seem to me to be the best description.

Granted, the prevailing winds, from the northeast to the southwest, appear to pushing the sand dune fields to the southwest. The dark line — created recently by a dust devil — indicates the wind direction. The mesas, from 100 to 200 feet high, do not however appear very streamlined. Instead, they simply look like they are poking up through this sea of sand and dunes, with the wind able over time to successfully push that sand uphill a hundred-plus feet into the saddle between the mesas.

The overview map below provides some context and possibly an explanation, though not a very conclusive one.

More bad journalism, this time about a hypothesized “underground ocean” on Mars

How today's journalists analyze potential stories
How today’s journalists analyze potential stories

Today’s example of modern bad journalism from our dismal mainstream press concerns a paper published yesterday in the journal of the National Academy of Sciences describing the possibility of liquid water in the Martian “mid-crust,” based on InSight seismological data and computer modeling.

I read the paper yesterday and decided that there really wasn’t much there. While the data suggests a lot of liquid water might be saturated within the fractured rocks of this deep underground crustal layer six to twelve miles down, the paper was based on many assumptions and had many uncertainties. It is also not confirmed by other researchers, and remains nothing more than educated speculation at this point.

Not surprisingly, our ignorant mainstream press today has immediately declared the discovery of a vast underground ocean on Mars, ready for the taking and possibly harboring life!

Orbital tug startup Astroscale expands partnership with European aerospace giant Airbus

9:36 am

The Japanese-based orbital tug startup Astroscale has signed an agreement with the European company Airbus to expand their partnership beyond an earlier agreement to use Airbus’s robot arm on Astroscale’s tug.

Under the MoU, Astroscale and Airbus will explore ways to boost the development of navigation and docking technologies for satellite servicing and debris removal missions they did not specify. According to the news release, the expanded partnership seeks to combine Airbus’s satellite manufacturing and space systems heritage with technologies Astroscale is developing for in-orbit servicing.

Astroscale has been aggressively working to get business both in Europe and the U.S. by opening divisions in both regions. This deal is clearly part of that effort. It also provides Astroscale resources as a new startup it previously did not have.

Axiom’s next commercial manned mission to ISS delayed until 2025

9:26 am

Axiom’s next commercial manned mission to ISS, dubbed Ax-4, which had been targeting an October 2024 launch date, has now been delayed until 2025 because of “required interagency approval processes.”

NASA’s only announcement describing the delay was a tweet on X, which stated the following:

The Ax-4 crew members are pending approval to fly to the orbiting lab by the Multilateral Crew Operations Panel.

Neither Axiom nor NASA provided further comment or explanation. The mission will fly three passengers from India, Poland, and Hungary and be commanded by Peggy Whitson, a former NASA astronaut who now fulfills that role for Axiom. Since the three passengers are all government astronauts, it is possible that the bureaucracies from all three nations, plus NASA and its ISS partners, are entangled in negotiations far more complex than necessary.

This situation highlights quite clearly why both billionairs Jared Isaacman and Chun Wang have signed on with SpaceX to flight orbital missions — avoiding a docking with ISS — that require no permissions from NASA. Wang for example announced his deal yesterday, for a flight that is targeting a launch before the end of the year. Though that schedule is tight and might not be met, it appears the mission will likely fly before the Axiom one, which has been planned now for quite awhile.

Portugal’s air traffic agency signs deal with company wishing to build spaceport in Azores

9:14 am

Santa Maria spaceport

Portugal’s air traffic agency, Portugal NAV, today signed an agreement with the spaceport company Atlantic Spaceport Consortium, to work out the details of placing a commercial spaceport on the island of Santa Maria in the Azores.

Under the cooperation agreement, the pair aim to define the guidelines that a future spaceport will need to adhere to when launching from Santa Maria. This includes defining exclusion zones, examining how to monitor and authorize launch activities, and studying under what conditions to impose partial or total launch restrictions for safety reasons.

The map to the right shows the location of the island, relative to Europe and Africa. No timeliine for construction has been given, though the consortium hopes to launch “a small atmospheric rocket” in September. It has also signed a deal in 2022 (just before Russia’s invasion) with a Ukrainian rocket startup.

SpaceX announces another commerical passenger flight on a Dragon capsule

10:17 pm

SpaceX today announced it will fly a four-passenger commerical flight, using the Dragon capsule dubbed Endurance and flying the first manned human flight to circle the poles.

The private Crew Dragon mission will be led by a Chinese-born cryptocurrency entrepreneur named Chun Wang, and he will be joined by a polar explorer, a roboticist, and a filmmaker whom he has befriended in recent years.

The “Fram2” mission, named after the Norwegian research ship Fram, will launch into a polar corridor from SpaceX’s launch facilities in Florida and fly directly over the north and south poles. The three-to-five day mission is being timed to fly over Antarctica near the summer solstice in the Southern Hemisphere, to afford maximum lighting.

As with the Jared Isaacman’s previous and future Dragon manned missions, the flight avoids any of the NASA bureucracy and costs by not docking with ISS. The flight is targeting a launch date before the end of this year, but that date is not firm.
