Pakistan to fly a small rover on China’s Chang’e-8 lunar lander

8:36 am

In an agreement signed yesterday, the Space and Upper Atmo­sphere Research Comm­ission (Suparco) in Pakistan announced it will collaborate with China to build a small rover that will to fly on China’s Chang’e-8 lunar lander.

The lander is present scheduled to land near the Moon’s south pole in 2030, will be China’s second lander to the south pole region, and will also act to officially establish China’s International Lunar Research Station (ILRS) on the lunar surface. It will also include a “hopper” to explore the nearby surface.

Pakistan had already signed on to China’s space alliance to build the ILRS. China’s present list of partners is as follows: Azerbaijan, Belarus, Egypt, Kazakhstan, Nicaragua, Pakistan, Russia, Serbia, South Africa, Thailand, Turkey, and Venezuela. That partnership also includes about eleven academic or governmental bureaucracies.

A return to Phantom and the reminiscences of an Apollo astronaut

3:04 pm

Charles Duke, Apollo 16 astronaut
Charles Duke, Apollo 16 astronaut

Yesterday I had to pleasure of getting my second tour of the Phantom Space facilities, located here in Tucson. Jim Cantrell, the founder of the Tucson-based rocket/satellite company Phantom Space, had last week graciously invited me to attend the event he was holding there, where astronaut Charles Duke, from the April 1972 Apollo 16 lunar landing, would be giving a talk to the company’s employees, investors, and customers. Duke had become an advisor for the company, and this would be his first visit to its operations.

First, the talk by Charles Duke, describing his life and Apollo 16 walk on the Moon, was as usual awe-inspiring, mostly because Duke spoke like every astronaut I’ve ever met so matter-of-factly about what he had done. During the second of three excusions on the surface with his commander John Young, they drove their rover up the slope of nearby Stone Mountain, climbing to an elevation of 500 feet, the highest any human has so far been on the lunar surface. From there he could look back and see for miles, including the entire valley where the lunar module was nestled as well as the mountains and craters that surrounded it.

When I asked him if he had had any sense of his remoteness from humanity, his response was a good-natured laugh. “We felt at home there!” They had done so much study of the terrain beforehand, including simulations, that from the moment they approached to land it all looked very familiar. This is where they were supposed to be!

Following Duke’s presentation we all were given a tour of the facility. My first visit there had been in 2022. At the time Cantrell’s effort was to aggressively succeed from his earlier failure at the rocket startup Vector, focusing this new company on building its Daytona rocket. After the tour I concluded as follows:

NASA picks nine lunar south pole candidate sites for Artemis-3 manned landing

10:37 am

Click for NASA’s original image.

NASA today revealed the nine candidate sites in the Moon’s south polar region for its Artemis-3 manned mission, presently targeting a 2026 launch date.

The map to the right shows the location of those nine sites, numbered in order of priority, as follows:

  • 1. Peak near Cabeus B
  • 2 . Haworth
  • 3. Malapert Massif
  • 4. Mons Mouton Plateau
  • 5. Mons Mouton
  • 6. Nobile Rim 1
  • 7. Nobile Rim 2
  • 8. de Gerlache Rim 2
  • 9. Slater Plain

The map also shows the planned landing sites for Intuitive Machine’s Athena lander in January 2025, and China’s Chang’e-7 lander in 2026, as well as where India’s Virkam lander touched down in 2023.

Cabeus B is likely the prime candidate site because its high elevation will make communciations easier, while placing it closer to the crater Cabeaus, which was impacted by the LCROSS mission in 2009 and found a significant signature of water in the ejecta plume of that impact.

To make a final decision NASA will be consulting all players, from the science community as well as the engineers. All of this however depends on other factors outside of science and engineering, mostly related to politics and practicality. The entire mission relies on the full version of the SLS rocket, the manned lunar version of SpaceX’s Starship, launched by Superheavy, and a working version of Lockheed Martin’s Orion capsule, none of which are presently flightworthy.

ISRO head unveils new timeline for major missions

10:06 am

The head of India’s space agency ISRO, S. Somanath, yesterday unveiled a new timeline for several of that nation’s major missions, both manned and unmanned.

The new timeline is as follows:

  • 2025: NISAR: a joint Indian-American radar orbiter, long delayed
  • 2026: Gaganyaan-1, India’s first manned orbital mission
  • 2028: Chandrayaan-4, an unmanned sample return mission to the Moon
  • 2028: Chandrayaan-5, a joint lander-rover to the Moon

The last project will be done in partnership with Japan, with India building the lander and Japan the rover.

2028 will be a very busy year for India in space. The Indian government had previously announced that ISRO would launch in 2028 the first module of its space station as well as a Venus orbiter.

Young lava on the Moon?

Young lava on the Moon?
Click for original image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on November 27, 2023 by Lunar Reconnaissance Orbiter (LRO) and was today featured by the science team. From their caption:

One of the early findings from the LRO mission was the discovery of volcanic features known as Irregular Mare Patches (IMPs) scattered across the nearside. These landforms are generally considered volcanic. However, their ages are hotly debated. They may be as young as 50 million years or as old as 3.5 billion years. The Aristarchus IMP (25.045°N, 313.233°E) is one of the smallest and most enigmatic IMP. The fact that this IMP is found within the Aristarchus crater ejecta suggests it formed after the crater, which is dated at 200 million years.

Alternatively, this IMP may have formed as part of ejecta emplacement from the Aristarchus crater forming impact. However, no other crater ejecta on the Moon exhibits a similar landform.

Astronomers for decades before and since Sputnick have reported what appears to be some activity in the Aristachus region, though none of those reports have ever been confirmed. In LRO’s long mission orbiting the Moon it has not yet detected any obvious changes there, suggesting that there is little or no present activity. These patches however appear to indicate activity in the relatively recent past.

The patches however also indicate activity that seems alien. Why would the lava form in this manner, as rough patch of knobs, sometimes aligned, sometimes not?

GAO: Next SLS Artemis launches will almost certainly be delayed

10:52 am

SLS's two mobile launchers, costing $1 billion
NASA’s bloated SLS mobile launchers

According to a new Government Accountability Office (GAO) report released yesterday, NASA’S continuing delays and technical problems building the various ground systems required for the next few Artemis launches will almost certainly cause those launches to be delayed.

The schedule at present is as follows:

  • September 2025: Artemis-2 will be the program’s first manned mission, taking four astranauts around the Moon.
  • September 2026: Artemis-3 will complete the first manned lunar landing.
  • September 2028: Artemis-4 will send four astronauts to the Lunar Gateway station in orbit around the Moon, and then complete the second manned lunar landing.

The GAO report notes at length that modifications to the mobile launch platform SLS will use on the first two missions is taking longer than planned. It also notes that the problems completing the second mobile launcher continue, with the budget growing from $383 million to $1.1 billion, and the work years behind schedule with no certainty it will be completed in time for the 2028 mission. These issues are the same ones noted by NASA’s inspector general in August 2024.

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry,
including “cavities resulting from the loss of large chunks”

This report focused exclusively on the scheduling delays for the ground systems that will be used by SLS for each launch. It did not address the serious questions that remain concerning the serious heat shield damage experienced by the Orion capsule when it returned to Earth on its first unmanned mission in late 2022. NASA has been studying that problem now for two years, and as yet has not revealed a solution.

I continue to predict that the first manned landing, now scheduled for 2026, will not occur before 2030, six years behind the schedule first proposed by President Trump but actually fifteen years behind the schedule initially proposed by President George Bush Jr in 2004. All in all, it will take NASA almost a third of a century to put American astronauts back on the Moon, assuming the landing occurs in 2030 as I now predict. Compare that with the development time of SpaceX’s Starship/Superheavy. Proposed in 2017, it is already flying, and will almost certainly complete its first private manned lunar mission and its first test missions to Mars by 2027. The contrast is striking.

More and more the entire part of Artemis run by NASA is proving to be the failed disaster I predicted it would be in 2011. No wonder former New York mayor Michael Bloomberg wrote an op-ed yesterday calling for its cancellation. Like most politicians, reality is finally percolating into his thick skull, though several decades late.

Axiom unveils its spacesuit design

2:57 pm

Axiom's moonsuit
Click for original image.

Axiom today unveiled its proposed spacesuit for NASA’s Moon missions, designed in partnership with the fashion company Prada.

The graphic to the left, cropped and reduced to post here, shows the suit. The letters refer to detailed descriptions contained in the full image.

The suit accommodates a wide range of crewmembers, including males and females from the first to 99th percentile (anthropomorphic sizing). It will withstand extreme temperatures at the lunar south pole and endure the coldest temperatures in the permanently shadowed regions for at least two hours. Astronauts will be able to perform spacewalks for at least eight hours.

The AxEMU incorporates multiple redundant systems and an onboard diagnostic system to ensure safety for crewmembers. The suit also uses a regenerable carbon dioxide scrubbing system and a robust cooling technology to remove heat from the system. It includes advanced coatings on the helmet and visor to enhance the astronauts’ view of their surroundings, as well as custom gloves made in-house featuring several advancements over the gloves used today. The spacesuit architecture includes life support systems, pressure garments, avionics and other innovative systems to meet exploration needs and expand scientific opportunities.

It appears the suit follows the design concept of the Russian Orlan suit, with access in and out using the backpack as the access hatch.

Axiom had won the $228 million contract to build this suit in 2022. In two years it is now testing the suit as it nears what it calls “the final development stage.” Compare that with NASA’s failed effort over fourteen years and a billion dollars to create its own suit, never getting much past powerpoint presentations.

Astrolab unveils small prototype unmanned rover

9:50 am

Astrolab, one of three companies with NASA design contracts to develop a manned lunar rover, yesterday unveiled a small prototype unmanned rover that the company has designed to test on the Moon and actually hopes to launch on Astrobotic’s Griffin lander.

In a presentation at the International Astronautical Congress here Oct. 15, Astrolab announced plans to build the FLEX Lunar Innovation Platform, or FLIP, rover for launch as soon as the end of 2025. The half-ton rover will have a payload capacity of 30 to 50 kilograms.

A key purpose of FLIP is to test key systems for its larger FLEX, or Flexible Logistics and Exploration, rover, maturing their technology readiness levels (TRLs). “We want to raise the TRL of our technologies ahead of our other missions,” said Jaret Matthews, founder and chief executive of Astrolab. FLIP will test the same battery modules that the larger FLEX will use and has the same tires as FLEX. Other technologies Astrolab plans to test on the smaller rover include actuators, power systems and communications.

Though no deal has been announced, FLIP was clearly designed to match the fit of NASA’s now canceled VIPER rover that was to be launched on Astrobotic’s Griffin lander. Griffin is still being prepped for its lunar mission to be launched in 2025, but no longer has that prime payload. It is very obvious that Astrolab is vying to make FLIP that prime payload.

If so, the company will have once again demonstrated the advantages of private enterprise. NASA spent almost a billion on VIPER, going so much over budget and behind schedule that the agency had to cancel it. Astrolab has now come up with a replacement in almost no time at all, for likely pennies on the dollar. It is for sure simpler, but it also is likely to fly and test engineering, while VIPER will not.

NASA extends the mission of the lunar orbiter Capstone to the end of 2025

9:36 am

NASA has now funded the mission of the privately built and operated lunar orbiter Capstone to the end of 2025, allowing it to complete engineering testing by more than two years of the orbit around the Moon that NASA’s Lunar Gateway space station intends to use.

Extending CAPSTONE’s mission also allows further collaboration with the Lunar Reconnaissance Orbiter (LRO) team at NASA’s Goddard Space Flight Center in Maryland. That partnership comes via a recently extended Space Act Agreement to evaluate, and when appropriate, conduct opportunities for cross-link data collection between the two spacecraft.

The spacecraft is entirely commercial, with NASA merely acting as the customer. It was built by Terran Orbital, launched by Rocket Lab, and is owned and operated by the private company Advanced Space, making it I think the first interplanetary probe operated entirely by the private sector for NASA. Advanced Space’s achievement was further magnified in shortly after launch the spacecraft had some thruster issues causing it to tumble. The company’s engineers were able to regain control and get it to the Moon.

Water on the Moon? New data analysis from two different lunar orbiters say yes

10:04 am

Two papers in the past month using data from two different lunar orbiters have claimed the presence of water on Moon, based on the detection of evidence of hydrogen on the surface.

First, on September 16, 2024 scientists published a paper [pdf] that analyzed data collected in 2009 by India’s Chandrayaan-1 lunar orbiter, and concluded, as stated enthusiastically in the press release:

Map of permanently shadowed regions at the Moon's south pole

regions at the Moon’s south pole. Click for original.

“Future astronauts may be able to find water even near the equator by exploiting these water-rich areas. Previously, it was thought that only the polar region, and in particular, the deeply shadowed craters at the poles were where water could be found in abundance,” said Roger Clark, Senior Scientist at the Planetary Science Institute and lead author of “The Global Distribution of Water and Hydroxyl on the Moon as Seen by the Moon Mineralogy Mapper (M3)” that appears in the Planetary Science Journal. “Knowing where water is located not only helps to understand lunar geologic history, but also where astronauts may find water in the future.”

Then today NASA announced the publication of a new paper [pdf] that looked at the data collected over the last decade by Lunar Reconnaissance Orbiter (LRO), and have concluded that “hydrogen-bearing volatiles are observed to be concentrated, likely in the form of water ice, within most of the Moon’s permanently shadowed regions (PSRs), poleward of 77°.” The press release, which included the map to the right of permanently shadowed areas at the Moon’s south pole, was more enthusiastic:

ISRO reveals design of its Chandrayaan-4 lunar sample return mission

9:23 am

India’s space agency ISRO yesterday unveiled its design concept for its Chandrayaan-4 lunar sample return mission, requiring two launches and five modules that will dock in Earth orbit before traveling to the Moon.

“After two launches, the stacks will be docked together in elliptical Earth orbit to form an integrated stack. Subsequent to docking, the Integrated Stack will perform the first set of Earth-bound manoeuvres with the PM propulsion system. Once the PM is depleted, it gets jettisoned from the Integrated stack,” Isro said Tuesday.

The integrated stack then performs all the manoeuvres to achieve the lunar orbit, such that the orbit plane has the pre-determined landing site. In the final lunar orbit, the descender module and ascender module get separated from the transfer module and re-entry module. The descender and ascender modules then undergo powered descent to achieve a soft landing on the lunar surface.

Both a robot arm and a drill will then grab samples, deposit them separately in the ascender, which will then launch and redock with the stack. It will then take the re-entry module back toward Earth, where it will be released prior to its return.

This plan is essentially the same as the first proposal last year, but with many more added details.

A landing site has apparently not yet been chosen.

China unveils proposed spacesuit for its planned manned lunar landings

11:24 am

China's proposed moonsuit
Click for original image.

China’s Manned Space Agency (CMSA) yesterday unveiled its proposed spacesuit for the planned manned lunar landings it hopes to achieve by 2030.

As shown on the left, the suit draws its design from the Russian Orlan suit. The large backpack-like unit is also a hatch. The astronaut opens it, drops into the suit, and then a partner closes the unit, locking it shut. The rest of the suit is a single piece, with the central body unit rigid and the arms and legs flexible.

The Russian’s Orlan suit has been upgraded a number of times over the years, but the basic design has proved to be practical, efficient, and reliable, generally the oppose of the unwieldy and complex American suits NASA has been using since the start of the shuttle era.

The announcement was made to initiate a contest for the public to pick a name for the suit. Like all such contests, the real goal is to provide bread-and-circuses to the public so that they can think they have some say in what is happening. In the end the government will pick the name, and find someone who made the same suggestion to “award” for the idea.

Scientists locate lunar impact crater produced by LCROSS in 2009

11:07 am

Figure 2 of research paper
Taken from figure 2 of the paper. Click for
original image.

Using orbital radar and opitcal images scientists finally believe they have identified the small crater on the Moon produced when — as part of the 2009 LCROSS mission — an abandoned rocket stage crashed in a permanently shadowed section of Cabeus crater near the lunar south pole.

LCROSS was designed to study the ejecta thrown up by that impact, and found “a significant amount of water, estimated at 5.6 ± 2.9% by mass, as well as minor amounts of other volatile species.” Because the impact was in that permanently shadowed region, however, locating the new crater required new instrumentation.

Using a radar instrument on Lunar Reconnaissance Orbiter (LRO) as well as the Shadowcam instrument on South Korea’s Danuri orbiter — designed to take optical images in very low light — the scientists pinpointed that impact crater, as shown in the image to the right, overlaying both the radar and optical images. The crater is estimated to be about 22 meters across, about 25% smaller than predicted. From this the scientists conclude that the water in the ejecta plume came from close to the surface, and thus could only have been placed there in the past billion years. Before that, the location was not in shadow, and volatiles like water could not have survived if they were near the surface.

From this data the scientists believe the water was likely placed there by the “recent delivery by comets or the solar wind, rather than as a paleo-reservoir from an early volcanic atmosphere.” If so, the amount of material can be reasonably predicted, and is likely less than hoped for because it only exists in the top two meters.

Lockheed Martin drops out of commercial manned lunar rover consortium

9:29 am

Lunar Outpost, one of the three companies/partnerships that have won NASA contracts to develop manned lunar rovers for the Artemis program, has replaced Lockheed Martin as one of its partners.

This fact was only made evident now, three months after Lockheed parted ways, with a statement that a new much smaller company, Leidos, has joined the consortium.

That statement listed the other members of the Lunar Dawn team: General Motors, Goodyear and MDA Space. Notably absent was Lockheed Martin, which Lunar Outpost had described as its “principal partner” on the rover when it won the NASA contract in April. The website for Lunar Dawn also did not list Lockheed Martin as a partner.

In a Sept. 25 interview, Justin Cyrus, chief executive of Lunar Outpost, confirmed that Lockheed Martin was no longer involved in the rover project. “We just weren’t able to reach an agreement as we were negotiating the terms and conditions of the statement of work for this contract,” he said.

Both Lunar Outpost and Lockheed Martin provided no specific reasons for the break-up, other than typical PR statements such as “it wasn’t a good fit for us or them.”

The rover being built is dubbed Lunar Dawn. The present NASA contract only covers the design phase. Once completed NASA will choose one consortium to build the rover itself, picking from either the Lunar Outpost design or the designs submitted by Intuitive Machines and Venturi Astrolab.

Sierra Space successfully tests equipment for extracting oxygen from the lunar soil

9:57 am

In a press release this week Sierra Space revealed that it has successfully tested an extraction system that can gather up the abrasive lunar regolith and then heat it to high temperatures in order to extract and use the oxygen contained in that soil.

Temperatures in which the Sierra Space Carbothermal Oxygen Production Reactor were tested ranged from minus 45 degrees Celsius to 1,800 degrees Celsius. In addition to the challenges of functioning from sub-zero to hotter-than-lava temperatures, the hardware was required to move the simulated lunar regolith – a very abrasive and jagged material because it does not have the weathering processes found on Earth – through its system. The potentially damaging particles were handled effectively by the hardware and gasses were successfully sealed inside the reactor, thanks to Sierra Space’s use of a patent-pending valve design that previously demonstrated functionality to greater than 10,000 cycles.

The tests confirmed that Sierra Space’s system can successfully handle regolith that would be delivered from a lunar rover or robotic arm and automatically bring it into the reaction chamber, perform the carbothermal reduction reaction process to extract the oxygen from the minerals in the regolith, and remove the processed regolith from the system so the operation can be repeated.

This research is similar to the extraction system the Chinese are developing, though it appears Sierra’s system appears considerably closer to a finished product, as it is already being tested.

Indian government approves major space projects, including new rocket, missions to the moon, space station, Venus

3:54 pm

The cabinet of Modi government in India today approved a whole range of major space projects for the next decade, including a sample return mission to the moon, the building of the first module of that country’s space station, an orbiter to Venus, and the development of a new more powerful but reusable rocket.

The lunar sample return mission, dubbed Chandrayaan-4, is targeting a launch about three years from now, and will be shaped to provide information leading to a manned lunar mission by 2040.

The cabinet also approved the development of the first module of its proposed Bharatiya Antariksh Station (BAS), targeting a 2028 launch date with the full station completed by 2035. This approval also included a plan for manned and unmanned missions leading up to the launch of that first module.

Under the programme eight missions are envisaged — four under the ongoing Gaganyaan programme by 2026, and development of BAS-1, and another four missions for demonstration and validation of various technologies by December 2028.

The Venus Orbiter is now targeting a 2028 launch.

The new launch rocket, dubbed the Next Generation Launch Vehicle (NGLV) will aim for reusability and be 1.5 times more powerful than the India’s presently most powerful rocket, the Launch Vehicle Mark-3 (LVM-3). The program to develop this new rocket however appears overally long (8 years) with relatively little flight testing (3 flights).

Overall, this government space program will likely energize India’s new commercial aerospace industry, as the Modi government is also attempting to shift as much of this work to private companies, rather than have its space agency ISRO do the work.

NASA awards Intuitive Machines $4.8 billion contract to build Moon communication satellite constellation

9:17 am

NASA yesterday awarded Intuitive Machines a contract worth as much as $4.8 billion to build the communication relay infrastructure necessary to support bases and research on the Moon.

This Subcategory 2.2 GEO to Cislunar Relay Services is a new firm-fixed-price, multiple award, indefinite-delivery/indefinite-quantity task order contract. The contract has a base period of five years with an additional 5-year option period, with a maximum potential value of $4.82 billion. The base ordering period begins Tuesday, Oct. 1, 2024, through Sept. 30, 2029, with the option period potentially extending the contract through Sept. 30, 2034.

Lunar relays will play an essential role in NASA’s Artemis campaign to establish a long-term presence on the Moon. These relays will provide vital communication and navigation services for the exploration and scientific study of the Moon’s South Pole region. Without the extended coverage offered by lunar relays, landing opportunities at the Moon’s South Pole will be significantly limited due to the lack of direct communication between potential landing sites and ground stations on Earth.

According to the company’s own press release, this relay system will include a “lunar satellite constellation,” though the number of satellites was not revealed. The system will provide not just communications but will include GPS-type location data for ground operations.

Intuitive Machines targeting January 2025 for launch of its next lunar lander

9:37 am

The landers either at or targeting the Moon’s south pole

The company Intuitive Machines is now aiming to launch its second Nova-C lunar lander, dubbed Athena, during a January 1-5, 2025 launch window.

The landing site is indicated on the map to the right, on the rim of Shackleton crater and almost on top of the south pole. While Chang’e-7 is targeting the same crater rim, it is not scheduled for launch until 2026.

The lander will not only include a drill for studying the surface below it, it will release a small secondary payload, the Micro-Nova Hopper, which will hopefully hop down into the permanently shadowed craters nearby.

The launch will also carry a lunar orbiter, dubbed Lunar Trailblazar, which will not only do spectroscopy of the lunar surface, looking for water, it will also be used as a communications relay satellite with Athena. That orbiter, designed to demonstrate the ability to build a smallsat at low cost, was previously threatened with cancellation because its builder, Lockheed Martin, went way over budget.

NASA receives 11 VIPER proposals from the private sector

10:58 am

NASA is now evaluating eleven different proposals from private companies to take over the agency’s canceled VIPER lunar rover.

Equipped with three scientific instruments and a drill, the rover was to be delivered to the Moon by a commercial lander, Griffin, built by Pittsburgh-based Astrobotic as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative. Astrobotic and several other companies have CLPS contracts to deliver NASA science and technology experiments to the Moon. NASA pays for delivery services for its payloads. The companies are expected to find non-NASA customers to close the business case.

NASA is paying Astrobotic $323 million for landing services on top of the cost of VIPER itself. NASA’s commitment to Congress was that VIPER would cost $433.5 million with landing in 2023. By the beginning of this year, that had become $505.4 million with landing in 2024.

It appears NASA canceled the VIPER mission because the agency had doubts Astrobotic would launch Griffin on time. The rover cost overruns, plus additional costs from that launch delay, made NASA management back out.

Though NASA has not revealed any details about the new eleven proposals, we know that Astrobotic’s competitor, Intuitive Machines, is one of those proposals. How it can get it launched to the Moon for less than it would have cost to launch on Astrobotic’s Griffin however is a mystery to me.

Meanwhile, Griffin is still going to launch, with Astrobotic now able to sell that VIPER payload space to others and NASA paying for the flight.

Ispace targeting a December launch for its second attempt to softland on the Moon

10:41 am

Landing zone for Resilience lander

At a press conference yesterday officials of the Japanese company Ispace announced that they are now targeting a December 2024 launch of their second Hakuto-R lunar lander, dubbed “Resilience”, with the landing site located in the high mid-latitudes of the near-side of the Moon.

The map to the right indicates that location, inside Mare Frigoris. Atlas Crater is where Ispace attempted but failed to soft land its first lunar lander, Hakuto-R1, in April 2023.

This new lander will be launched on a Falcon 9 rocket. It carries six commercial payloads. It also appears the company decided to go for an easier landing site on this second mission. Rather than try to land inside a crater, it is targeting a very large and flat mare region, thus reducing the challenges presented to its autonomous software.

Ispace already has contracts both with NASA ($55 million) and Japan’s JAXA space agency ($80 million) for two more future landers, so a successful landing this time is critical to the company’s future.

China significantly expands its international partners for its planetary program

10:34 am

According to China’s state-run press, it has recently signed cooperative agreements with a significant number of new nations for either its International Lunar Research Station project (ILRS) or other deep space planetary missions.

During the opening ceremony of a two-day space conference held in Tunxi, east China’s Anhui Province on Thursday, the China National Space Administration (CNSA) and its counterpart in Senegal signed an agreement on International Lunar Research Station (ILRS) cooperation.

At the conference, China’s Deep Space Exploration Lab (DSEL) inked memoranda of understanding with 10 institutions from countries including Serbia, Switzerland, the United Arab Emirates, Indonesia, Pakistan, Panama and South Africa. Also among the institutions are the Belt and Road Alliance for Science & Technology, the Foundation for Space Development Africa, and Africa Business Alliance.

Senegal is now the thirteenth nation to join China’s lunar base project, following Azerbaijan, Belarus, Egypt, Kazakhstan, Nicaragua, Pakistan, Russia, Serbia, South Africa, Thailand, Turkey, and Venezuela. That partnership also includes about eleven academic or governmental bureaucracies.

The agreements involving China’s deep space exploration involve other missions to other planets, with those nations either providing science instruments or some other contribution. That Switzerland and the United Arab Emirates have signed deals suggests there is a rising desire in the west to team up with China because of its general success in space, compared to the problems other nations often experience when dealing with NASA and the U.S. If so, the competition will certainly heat up in the coming years. I hope in this competition that American private enterprise can make up for the failures of our government.

Russia claims its next unmanned Moon mission, Luna-26, is on schedule

9:09 am

Phase I of China/Russian Lunar base roadmap
The original phase I plan of Chinese-Russian lunar
base plan, from June 2021.

According to Russia’s state-run press, its next unmanned Moon mission, Luna-26, is on schedule for a planned launch in 2027, though that press also claims the launch may happen in 2026 instead.

The problem with this claim is that Russia had for years said that this lunar orbiter would launch by 2025. As expected, the mission has not launched on time, as have all of Russia’s 21st century lunar exploration plans. For example, the previous lunar mission, the Luna-25 lunar lander, was originally supposed to land on the Moon in 2021, was not launched until 2023, and ended up crashing on the Moon when the spacecraft did not function properly during a engine burn in lunar orbit.

In the first phase of the so-called China-Russian partnership to explore the Moon, is shown by the 2021 graph to the right, China continues to do all the heavy lifting, and do so pretty much on the schedule predicted. Russian meanwhile continues to do what I predicted back in 2021, get nothing done on time and when launched have problems.

NASA awards Intuitive Machines a new lunar lander contract

NASA yesterday announced that it has awarded Intuitive Machines a new lunar lander contract for $116.9 million to carry six NASA/ESA payloads to the surface of the Moon.

The announcement stated that the landing will be in the south pole region of the Moon, but did not reveal the specific location. Of the six science packages, the most important is a European Space Agency-led drill that will obtain samples from as much as three feet down and then analyze them.

The contract calls for a 2027 landing, and will be the fourth targeting the south pole region, following Intuitive Machines first attempted landing there early this year that landed but then tipped over, preventing its science instruments from functioning as planned.

Firefly this week completed the integration of the ten customer payloads onto its first Blue Ghost lunar lander and shipped the lander to JPL in California for final environmental testing before its planned launch before the end of this year.

Following final testing, Firefly’s Blue Ghost will ship to Cape Canaveral, Florida, ahead of its launch on a SpaceX Falcon 9 rocket scheduled for Q4 2024. Blue Ghost will then begin its transit to the Moon, including approximately a month in Earth orbit and two weeks in lunar orbit. This approach provides ample time to conduct robust health checks on each subsystem and begin payload operations during transit.

Blue Ghost will then land in Mare Crisium, a basin in the northeast quadrant on the Moon’s near side, before deploying and operating 10 instruments for a lunar day (14 Earth days) and more than 5 hours into the lunar night.

Once launched, Firefly will become the third American company, after Astrobotic and Intuitive Machines, to build a privately owned lunar lander and attempt a lunar landing. Since the other two companies were not entirely successful in their landing attempts, Firefly has the chance to be the first to succeed.

First high resolution images released from Juice’s fly-by of the Earth & Moon

The Italian science team that runs the high resolution camera on the asteroid probe Juice have now released that camera’s first images, taken to test its operation during the spacecraft’s close fly-by of both the Moon and then the Earth a week ago.

The picture to the right, cropped, reduced, and sharpened to post here, shows the Moon’s surface during that close fly-by, which got within 435 miles. The camera is dubbed Janus, and was developed by Italy and operated by the Italian National Institute for Astrophysics.

JANUS will study global, regional and local features and processes on the moons, as well as map the clouds of Jupiter. It will have a resolution up to 2.4 m per pixel on Ganymede and about 10 km per pixel at Jupiter.

The main aim of JANUS’s observations during the lunar-Earth flyby was to evaluate how well the instrument is performing, not to make scientific measurements. For this reason, JANUS took images with various camera settings and time intervals – a bit like if you’re going out to test a DSLR camera for the first time. In some cases, researchers intentionally ‘blurred’ the images so that they can test out resolution recovery algorithms. In other cases, they partially saturated the image to study the effects induced on the unsaturated areas.

As can be seen by the sample image above, the test images appear to have demonstrated that Janus will function as planned when Juice arrives in orbit around Jupiter in 2031 in order to study that gas giant’s upper atmosphere as well as its larger icy moons, Ganymede, Calisto, and Europa.

JAXA finally shuts down SLIM operations after four months of no contact

Japan’s space agency JAXA today announced that it has now closed down all further attempts to contact its SLIM lunar lander on the surface of the Moon.

The Japan Aerospace Exploration Agency (JAXA) concluded operations of the Smart Lander for Investigating Moon (SLIM) on the lunar surface at 22:40 (JST), on August 23, after being unable to establish communication with the spacecraft during the operational periods from May to July*, following the last contact on April 28, 2024.

SLIM was launched onboard the H-IIA Launch Vehicle No.47 (H-IIA F47) on September 7, 2023 from the Tanegashima Space Center and achieved Japan’s first Moon soft landing on January 20, 2024. The landing precision was evaluated with a position error of approximately 10 meters from the target point, confirming the world’s first successful pinpoint landing. In addition, the Multi-Band Camera (MBC) successfully performed spectral observations in 10 wavelength bands on 10 rocks, exceeding initial expectations. Further, despite not being part of the original mission plan, the spacecraft was confirmed to survive three lunar nights and remained operational, demonstrating results that surpassed initial goals.

The lander’s main goal was to demonstrate the ability to do a precise robotic landing within a 100 meter landing zone. And even though one nozzle fell off during landing, resulting in SLIM landing on its side, it accomplished that goal and then survived three lunar nights, exceeding significantly its expected ability to function in harsh lunar environment.

The image to the right, reduced to post here, was taken by SLIM just before it was shut down for its first lunar night. It looks to the southeast across the width of 885-foot-wide Shioli Crater, the opposite rim the bright ridge in the upper right about a thousand feet away.

Chinese scientists find method to extract water from Chang’e-5 lunar samples

Proposed concept for extracting water from lunar regoilth
Proposed concept for extracting water from
lunar regoilth

Chinese scientists have found that by heating Chang’e-5 lunar samples to 1,700 degrees Fahrenheit it is possible to extract a significant amount of water. From the paper’s abstract:

FeO and Fe2O3 are lunar minerals containing Fe oxides. Hydrogen (H) retained in lunar minerals from the solar wind can be used to produce water. The results of this study reveal that 51–76 mg of H2O can be generated from 1 g of LR [lunar regolith] after melting at temperatures above 1200 K. This amount is ∼10,000 times the naturally occurring hydroxyl (OH) and H2O on the Moon. … Our findings suggest that the hydrogen retained in LR is a significant resource for obtaining H2O on the Moon, which are helpful for establishing scientific research station on the Moon.

A video in Chinese (hat tip BtB’s stringer Jay) that describes this research can be found here. (If any of my readers understands Chinese and can provide a translation of this video’s narration, I would be very grateful.) It includes an artist’s rendering (screen capture to the right) showing how such a system on the Moon could work to extract water from the soil. Sunlight would be focused by a lensed mirror into a glass-domed container, heating the ground. The water would evaporate, condense on the glass and be sucked into a tube that would transfer it to a water tank.

This design is of course very simple and preliminary. According to Jay, “They need to heat the soil to 1000℃ (1832°F) to get the iron oxide in the lunar soil to split, the oxygen combines with hydrogen to make water and iron (melting point of iron is about 1500℃). You will need a nuclear reactor to produce that much power for an inductive furnace to get that hot. Doing the calculation, it would take about 245kw to heat up a metric ton of dirt in one hour to a 1000℃ degrees. It could be done slower over 24 hours at 10kw.”

Despite the technical difficulties getting such equipment operational on the Moon, that this research suggests water can be produced practically anywhere on the lunar surface is signficant. It suggests that even if no easily accessible water ice is found in the permanently shadowed craters at the poles, lunar bases still have viable options for obtaining water, and they don’t have even be at the poles.

Pragyan data confirms theory that the Moon’s surface was once largely covered with molten lava oceans

Data from India’s Pragyan lunar rover that landed in the high southern latitudes of the Moon in August 2023 has now confirmed the theory that the Moon’s surface was once largely covered with molten lava oceans.

Santosh Vadawale, an X-ray astronomer at the Physical Research Laboratory in Ahmedabad, India, and his colleagues analysed radiation data collected by the APXS [one of Pragyan’s instruments], and used this information to identify the elements in the regolith and their relative abundances, which, in turn, revealed the soil’s mineral composition. The team found that all 23 samples comprised mainly ferroan anorthosite, a mineral that is common on the Moon. The results were reported in Nature today.

“It’s sort of what we expected to be there based on orbital data, but the ground truth is always really good to get,” says Lindy Elkins-Tanton, a planetary scientist at Arizona State University in Tempe.

Previous landers obtained similar results. However, the Chandrayaan-3 samples are the first from the subpolar region: previous landers visited equatorial and mid-latitude zones. Together, this suggests that the composition of the regolith is uniform across the Moon’s surface.

These results are no surprise, but they confirm the global nature of the Moon’s early molten history. More important, they demonstrate that India now has the capability to send landers and rovers to other planets that are also capable of doing real research.

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.
