Vikram finds temperatures of lunar soil varies significantly, depending on depth

9:17 am

Temperature range of soil at Vikram landing site

Based on data from one of the instruments on India’s lunar lander Vikram, scientists have found that the temperatures of the lunar soil at the landing site vary significantly, depending on depth. The temperature dropped from 55 degrees Celsuis to -10 degrees Celsuis when going from about 10 millimeters above the surface to about 82 millimeters below the surface, as shown in the graph to the right.

That’s equivalent from going from a summer day in Death Valley of 131 degrees Fahrenheit to a winter day in Minnesota of 14 degrees Fahrenheit, in a distance of only about 3.5 inches. While it was expected that there would a temperature drop, it appears the quick temperature drop just below the surface was faster than expected.

JAXA scrubs launch of X-Ray telescope & SLIM lunar lander due to high winds

8:57 am

SLIM's landing zone
Click for interactive map.

Because of high winds, Japan’s space agency JAXA yesterday scrubbed the last launch of its H2A rocket, carrying the XRISM X-Ray telescope and the SLIM lunar lander.

A nice description of both payloads can be found here. XRISM is a simplified reflight of the Hitomi X-Ray telescope that failed immediately after launch in 2016.

Though SLIM carries a camera and two secondary payloads, both designed to hop along on the surface and obtain some data, its main mission is engineering, testing whether a robotic spacecraft can achieve a precision landing with a target zone of 100 meters, or 310 feet. The map to the right shows SLIM’s landing site, with the white dot in the close-up inset a rough approximation of that entire target zone. If successful this technology will make it possible to put unmanned planetary probes in places previously thought too dangerous or rough.

All three craft are designed to operate for only about fourteen days, during the daylight hours of the 28-Earth-day-long lunar day.

Update on ESA’s much delayed Space Rider X-37B copy

10:34 am

Link here. Space Rider is essentially aiming to be another re-usable mini-shuttle like the X-37B and the unnamed classified version from China. While all three are government-owned and government-run, the X-37B and China’s both were built expressly to do military classified missions. There has been no effort in either case to make them available for commercial flights.

The European Space Agency (ESA) however is developing Space Rider instead for commercial customers. It also appears the government-owned and government-run nature of Space Rider is one of the main reasons it will not fly its maiden mission this year, and won’t fly until late 2025, at the earliest.

“As an outcome of the previous ministerial council of 2019, the Space Rider received quite significant financial support to cope with Phase C and D activities. However, the participating states contributed in a way that was not possible — due to the need to comply with the Geo-return mechanism — to keep the industrial consortium as it was operating up to that moment [end-2019],” Galli said.

ESA’s Geo-return mechanism was established to boost fairness among member states, ensuring that the nations that invest in the agency will generate a “fair return.” In a nutshell, participating states in an optional development program should receive industrial contracts in a proportional way with respect to their contribution to that program to ensure that money invested benefits the countries that actually contributed to that program. That is to say for example, if you put 30% of the funds into the program, you are expected to receive as close as possible to industrial contracts accounting for 30% of the overall program.

As the program must abide by the Geo-return mechanism, Galli explained that the initial consortium involved was required to significantly be rebuilt “in compliance with the available funds and their member state relevant origin. … This caused first a not negligible delay in setting up the new industrial consortium… that was finally concluded only in late 2020 with the signature of the new contract with the prime contractors. And then, a so-called bridging design phase was needed on the subsystems affected by the change of industrial supplier, resulting in a longer-than-expected completion of the design phase.

In other words, Space Rider can’t just sell payload space to anyone. Only private businesses in those nations who help finance it can bid, and the customers don’t match well with the ESA’s nations that had been doling up the money. The consequence apparently has been a lot of complex negotiations and jury-rigging to make the two match, all of which has nothing to do with producing a viable product that makes money.

SpaceX completes successful 6-second static fire test of Superheavy

11:28 am

screen capture during static fire test
Screen capture during static fire test

SpaceX today successfully completed a full 5-second static fire test of all 33 Superheavy Raptor-2 engines as well as the deluge system of the launchpad at Boca Chica.

The link goes to the live stream, which is still on-going. The static fire test occurs at about 42 minutes, if you wish to see it.

According to the narrators of the live stream, Elon Musk tweeted that the static fire was a success. It certainly appeared to go for the full five seconds, and it certainly appeared more robust than the previous test. We will have to wait however for confirmation that all 33 engines fired as planned.

The company clearly appears just about ready to do an orbital test flight. Too bad the Biden administration still stands in the way. There is yet no word on when the FAA will approve a launch license, and the decision of the Justice Department yesterday to file a bogus discrimination lawsuit against SpaceX strongly suggests the White House is working hard to figure out ways to squelch this private effort by an American citizen and his company.

Flow channels on Mars

11:13 am

Flow channels on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on May 13, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists call a “channel and depression”, though to my eye everything looks like flow channels, descending to the east.

The drop from the narrow northern channel to wider southern channel is about 200 feet, with the small crater on the left sitting about halfway between. To our Earthbound eyes, something clearly flowed downhill from that northern channel into the wider channel. What we don’t know now is what the material was that did the flowing?

Was it liquid water? Glaciers? The overview map below provides some context, though it doesn’t actually provide an answer.

Both Vikram and Pragyan functioning as planned on the Moon

9:29 am

Pragyan on the Moon
Click to see full movie.

According to tweets from India’s space agency ISRO, both the Vikram lander and the Pragyan rover are functioning as planned on the lunar surface, with the rover successfully activating its two science instruments.

The image to the right, taken by Vikram, shows the rover as it completed its roll down the ramp onto the lunar surface. This is a screen capture from a movie showing that roll down, which you can see by clicking on the picture. Since then it has moved another 26 feet from the lander.

I must add once again that Vikram did not land “on the south pole”, as too many so-called news organizations have been falsely claiming. It landed at about 69 degrees south latitude, quite a distance from that pole, in a flat region with no permanently shadowed craters. It is not specifically looking for water, though its instruments might help explain the orbital data that suggests there are areas on the surface of the Moon where hydrogen is somehow present.

If so many news outlets can’t seem to get these very basic facts about this mission correct, one must ask what else do they get wrong routinely? I don’t ask, because I always assume their information is wrong, check it constantly, and find repeatedly that they get numerous basic facts incorrect, especially when it comes to reporting on politics.

China launches remote sensing satellite using rocket from pseudo-company

9:00 am

The Chinese pseudo-company Galactic Energy completed another successful orbital launch today, using its Ceres-1 rocket solid-fueled rocket carrying a remote sensing satellite and lifting off from the Jiuquan spaceport in the northwest interior of China.

As with the pseudo-company’s previous launch, the state-run press made no mention of the company in its reporting, underlining the fact that it really is simply another government-controlled entity that simply adds private investment and the profit-motive to its operations.

No word on where the rocket’s lower stages crashed within China.

The leaders in the 2023 launch race:

57 SpaceX
37 China
12 Russia

In the national rankings, American private enterprise still leads China in successful launches 66 to 37. It also leads the entire world combined, 66 to 60, while SpaceX by itself now trails the rest of the world (excluding American companies) 57 to 60 in successful launches.

  • Perseverance science team touts rover’s 19th core sample

    • If you listen closely to the two scientists in the video, they really can only guess about much of this geology, since Perseverance does not have the same geological capabilites as Curiosity. They can make some superficial analysis of the rocks, but the more detailed work will have to wait until those core samples are returned to Earth. Curiosity however can not only drill, but it has equipment to analyze those drill samples itself, there. While Curiosity can’t do what an Earth lab would do, it does it now. With Perseverance we will have to wait a decade or more to get to the samples.

Big mountains everywhere inside Valles Marineris

Big mountains in Valles Marineris
Click for original image.

While the giant canyon Valles Marineris on Mars is known best as the biggest known canyon in the solar system — large enough to cover the continental United States several times over — that size tends to diminish the mountainous nature of its interior. Today’s cool image attempts once again (see for example these earlier posts here, here, here, here, and here) to illustrate that stupendous and mountainous nature.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on May 15, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The goal of the picture was to get a better view of the numerous layers of this terraced cliff wall. What I see, however from my tourist’s perspective, is a steep wall that descends almost 4,500 feet from the high to the low point in just over three miles. This is as steep if not steeper than the walls of the Grand Canyon.

Biden’s Justice Department sues SpaceX

9:51 am

The corrupt and very partisan Justice Department of the Biden administration today sued SpaceX for discriminating against refugees and illegal immigrants because it restricts hiring to “U.S. citizens and lawful permanent residents.”

The lawsuit states SpaceX “failed to fairly consider” and “refused to hire” the asylees and refugees who ended up applying anyway. It also alleges that SpaceX “wrongly claimed” that the US’s export control laws allowed it to only hire US citizens and lawful residents. Additionally, the DOJ claims SpaceX hired “only” US citizens and green card holders from September 2018 to September 2020.

“Our investigation found that SpaceX failed to fairly consider or hire asylees and refugees because of their citizenship status and imposed what amounted to a ban on their hire regardless of their qualification, in violation of federal law,” Kristen Clarke, the assistant attorney general of the DOJ’s Civil Rights Division, says in a statement.

Justice is demanding compensation and back pay for anyone “deterred or denied employment”, as well as civil penalties.

This suit is utter garbage and puts SpaceX between a rock and a hard place. I guarantee if SpaceX had hired any illegal or refugee who was not yet a legal citizen, Biden’s State Department would have immediately sued it for violating other laws relating to ITAR (the export control laws mentioned) which try to prevent the theft of technology by foreign powers.

The Biden administration considers Elon Musk an opponent, and since it is now moving to indict and even imprison all political opposition, it is no surprise it is beginning to use lawfare against him. As I have written repeatedly, it has almost certainly pressured the FAA to slow walk any launch license approvals for SpaceX’s Starship/Superheavy. This lawsuit today simply provides further evidence that my prediction will be right that the next orbital test flight of that rocket will be delayed months.

North Korea fails again to get a military reconnaissance satellite into orbit

9:33 am

According to a report in North Korea’s state run press, a launch attempt of its new rocket Chollima-1 rocket failed to reach orbit at dawn today, its payload of a classified military reconnaissance satellite falling into the ocean.

The Korean Central News Agency (KCNA) in Pyongyang reported that the National Aerospace Development Administration launched the new Chollima-1 rocket “at dawn” August 24 from the Sohae Satellite Launch Center. The first and second stages worked as planned, but “the launch failed due to an error in the emergency blasting system during the third stage flight” according to KCNA.

South Korea’s Yonhap news agency identified the satellite as Malligyong-1, a military reconnaissance satellite and reported the launch time as 3:50 am local time (2:50 pm August 23 EDT).

The flight path can be found here. An earlier attempt in May failed also, but the cause was not specified. South Korea did recover the first stage and satellite from the May failure, claiming later the satellite had “no military utility.”

I expect South Korea to once again attempt recovery operations, but because the rocket traveled farther I also expect the chances of any recovery of material to be more unlikely.

India’s Pragyan rover has successfully been deployed on the lunar surface

9:23 am


Click for interactive map.

According to a tweet from India’s space agency ISRO late yesterday, the Pragyan rover has successfully rolled down its ramp and is now deployed on the lunar surface.

No further updates have yet been released. According to ISRO’s mission webpage the instruments on both Vikram and Pragyan are as follows:

Lander payloads: Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure the thermal conductivity and temperature; Instrument for Lunar Seismic Activity (ILSA) for measuring the seismicity around the landing site; Langmuir Probe (LP) to estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is accommodated for lunar laser ranging studies.

Rover payloads: Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of landing site.

Pragyan’s two spectroscopes are likely similar to instruments on Curiosity and Perseverance on Mars, and allows some good surface analysis. Without a scoop however there will be no analysis of anything below the ground, unless the rover can upend a rock using its wheels.

Rocket Lab launches a satellite reusing one rocket engine from previous flight

9:20 pm

Rocket Lab not only successfully launched a satellite tonight (August 24 in New Zealand), its first stage used a rocket engine that had flown previously.

In addition, the first stage was designed to be reused, and was quickly recovered after it splashed down in the Pacific. The plan is to refly either this or another recovered first stage in one of the company’s upcoming launches in the coming months, making Rocket Lab the second private company in the world, after SpaceX, to reuse a first stage.

The leaders in the 2023 launch race:

57 SpaceX

Where the Martian landscape begins to dry out

Where Mars begins to dry out
Click for original image.

Today’s cool image to the right, cropped, reduced, and sharpened to post here, provides us a glimpse at the lower mid-latitudes of Mars where the terrain is beginning to dry out as we move south. The picture was taken on April 29, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the scientists label “large linear features.”

The main north-south ridge is only about 20-25 feet high, and its meandering nature (which can be seen more clearly in the full image) suggests it is possibly an inverted channel, formed when the bed of a former canyon gets compressed by the water or ice that flows through it, and when the surrounding terrain gets eroded away that channel bed becomes a ridge.

These ridges however could also possibly be volcanic dikes, where magma had pushed up through fractures and faults to form these more resistant ridges.

First mission in Isaacman’s private space program delayed again

9:56 am

The first mission in the Polaris space program of manned flights by billionaire Jared Isaacman, using SpaceX’s manned spacecraft and rockets, has now been delayed until early in 2024.

Isaacman, in the podcast interview, suggested the delays were linked to the development of a new spacesuit required for a spacewalk, the first by a private astronaut mission, planned for Polaris Dawn. “We’ve had a little bit more free time this summer than we probably would have expected,” he said, which he attributed to the timing of spacesuit development and training. That effort “doesn’t always sync up, so we’ve had a little more free time with family and work this summer.”

That new suit, billed as the first new spacesuit developed in the United States in four decades, is critical to future human activities on moon and Mars, he argued. “We’re going to need spacesuits that don’t cost hundreds of millions of dollars in order to do that. We’re pretty excited because the suit that we are testing out, the evolution of it someday could be very well worn by people that are walking on the moon or Mars.”

This mission, dubbed Polaris Dawn, will use a Falcon 9 and one of SpaceX’s fleet of four manned Dragon capsules to spend several days in Earth orbit while conducting that first private spacewalk. Isaacman’s entire Polaris program includes two more manned missions,the second possibly aimed at raising and even doing maintenance on the Hubble Space Telescope, and the third using Starship to go around the Moon.

Isaacman has already flown one private mission in space, in 2021, dubbed Inspiration4. It flew for three days in orbit, carrying four passengers, including Isaacman himself. Since it did not dock with ISS, it was an entirely private manned mission, with no significant government involvement.

Space junk that ESA demo mission intends to de-orbit as been struck by another piece of space junk

9:44 am

In a strange bit of irony, an abandoned payload adapter from a mission launched a decade ago that a European Space Agency (ESA) mission was planning on capturing and de-orbiting has been hit by another piece of space junk, creating additional bits debris around it.

The adapter is a conical-shaped leftover, roughly 250 pounds (113 kg) in mass, from a 2013 Vega launch that sent a small fleet of satellites into orbit. Space tracking systems found new objects nearby the adapter, which ESA learned about on Aug. 10. The objects are likely space debris from a “hypervelocity impact of a small, untracked object” that smacked into the payload adapter, the agency said. We may never know if the crashing object was natural or artificial, given it didn’t appear in tracking systems.

The ESA mission, dubbed Clearspace-1, intends to launch in 2026 and use four grappling arms to grasp the payload adapter, after which both shall be sent to burn up in the atmosphere. Its goal is to demonstrate technology for removing space junk. This event, creating extra debris pieces around the payload adaptor, puts a kink on that mission while also underlining the need for such technology.

Mission engineers now have three years to figure out what, if anything, they need to do to deal with the extra debris. The good news so far is that it appears the payload adapter remains intact, its orbit has not changed, and the surrounding debris appears small enough to pose “negligible” risk.

India successfully lands Vikram on the Moon

9:10 am


Click for interactive map.

India this morning successfully placed its Vikram lander, carrying its Pragyan rover, on the surface of the Moon in the high southern latitudes.

I have embedded the live stream below, cued to just before landing.

The next challenge is getting Pragyan to roll off Vikram, and spend the next two weeks exploring the nearby terrain. The mission of both it and Vikram is only planned to last through the daylight portion of the 28-day-long lunar day, so it is not expected for either to survive the lunar night. Both will make observations, but the main purpose of this mission has already been accomplished, demonstrating that India has the technological capability to land an unmanned spacecraft on another planet. That the landing was in the high southern latitudes added one extra challenge to the mission.

Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on June 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as “The tip of Cerberus Fossae,” a thousand-mile-long crack in the surface of Mars formed when the ground was pulled apart by underground forces.

If you look closely at the picture’s right edge, you can see that beyond the end of the fissure it actually continues but appears filled with material. In the full picture this however is the end of the crack. Beyond this point the ground is as smooth and as generally featureless as seen within the picture itself, and as also shown in this MRO context camera view of the same area.

Cerberus Fossae is actually three parallel cracks, with this the northernmost one. The eastern tip of the middle crack was previously highlighted in a cool image in July 2022.

Proposed Las Vegas spaceport signs deal with launch startup

9:46 am

A private spaceport proposed for the desert west of Las Vegas has signed a deal with launch startup company to wants to use a 747 to launch reusable rockets.

Robert Lauer, director of Las Vegas Spaceport, announced a partnership with O-G Launch, a company headed by Robert Feierbach. Feierbach’s company aims to be a part of the commercial space industry by launching satellites from recyclable rockets deployed from large jets.

Terms of the partnership were not disclosed, but it is expected that companies seeking to deploy satellites would use O-G Launch aircraft starting from the Las Vegas Spaceport to launch a satellite-bearing rocket from 40,000 feet.

To put it mildly, this project is hardly a spaceport. It is planned as a casino, a resort, and a flight school with a runway. O-G helps give it the appearance of a spaceport by allowing it to claim orbital launches will take place there. Whether O-G ever takes off is another thing entirely. Its presence as part of the project, however, provides great PR for attracting customers to the proposed resort/casino.

Redwire to build biotech lab in Sierra Space’s LIFE space station

9:38 am

Sierra Space announced yesterday that — as part of its private space station module dubbed LIFE — it is partnering with Redwire to install a commercial biotech lab in the module.

The hardware includes equipment that Redwire has previously developed for the International Space Station, such as the Advanced Space Experiment Processor, which hosts biotech experiments. A particular focus will be on crystallization experiments, using the microgravity environment to grow larger crystals that can then be studied to determine their structure for pharmaceutical applications.

The companies did not disclose terms of the contract other than that Redwire will start delivering hardware in the fourth quarter of this year. Gold said that the companies will also partner on business development to identify customers for using the experiment platform.

The target date for the launch of LIFE is presently 2026, though it was not revealed when Redwire’s equipment would be installed.

What struck me about this deal is the shrinking mention of Blue Origin. Originally that company was listed as one of the major players in building this private space station, dubbed Orbital Reef, in which LIFE is only the first module. In the past year however its participation seems less and less significant in every subsequent press release. It appears to still be part of the project, but it is Sierra Space that is leading the effort, and appears to be making things happen.

But then, the track record of Blue Origin is to not make things happen. It could very well be that events are once again overtaking it. Sierra Space can’t wait for Blue Origin to slowly get its act together. It is finding ways to get things done, even if that means Blue Origin gets left behind.

Space Force awards multi-satellite contracts to Lockheed Martin and Northrop Grumman

9:26 am

Capitalism in space: In what is a landmark deal indicating the complete shift by the military from building its own satellites to letting private enterprise do it, the Space Development Agency (SDA) of the Space Force yesterday announced it has awarded Lockeheed Martin and Northrop Grumman each a contract to build and operate 36 satellites.

The 72 satellites will make up a portion of SDA’s network known as Tranche 2 Transport Layer. SDA is building a large constellation called the proliferated warfighter space architecture that includes a Transport Layer of interconnected communications satellites and a Tracking Layer of missile-detection and warning sensor satellites. Northrop Grumman’s contract for 36 satellites is worth approximately $733 million. The agreement with Lockheed Martin, also for 36 satellites, is worth $816 million, SDA said.

What makes this contract different than previous military satellite contracts is that the military will do relatively little design. It has released the basic specifications, and is asking private enterprise to do the work for it. It is a customer, not a builder. When the military attempted its own design and construction, the job would take sometimes a decade or more, cost many billions (with cost overruns), and often failed. This new constellation is targeting a 2026 launch, only two years from now.

The constellation will also be more robust than the gold-plated giant satellites the military would build previously. Rather than rely on a single do-it-all satellite which is easy to take out, the constellation has many satellites, and can easily compensate if one or even a few are damaged or destroyed.

This shift was one of the fundamental reasons the military wanted to create a separate Space Force. As part of the Air Force the office politics within that branch of the military had been impossible to make this shift. Too many managers in the Air Force liked building big gold-plated satellites. Once the Space Force took over those managers were taken out of the equation.

Russian engineers pinpoint approximate crash site of Luna-25

9:07 am

Russian engineers have pinpointed the approximate crash site of Luna-25 on the Moon as the 42-mile-wide crater Pontecoulant G, located at about 59 degrees south latitude, 66 east longitude.

Researchers from the Russian Academy of Sciences’ Keldysh Institute of Applied Mathematics have simulated the trajectory of the Luna-25 mission, figuring out where and when it crashed into the moon’s surface, the institute said in a statement on Telegram. “The mathematical modeling of the trajectory of the Luna-25 spacecraft, carried out by experts from the Ballistic Center of the Russian Academy of Sciences’ Keldysh Institute of Applied Mathematics, made it possible to determine the time and place of its collision with the moon,” the statement reads.

According to the institute, the spacecraft fell into the 42-kilometer Pontecoulant G crater in the southern hemisphere of the moon at 2:58 p.m. Moscow time on August 19.

The planned landing site, in Boguslawsky Crater at 73 degrees south latitude and 43 degrees east longitude, was many miles away.

SpaceX launches 21 Starlink satellites using Falcon 9

8:50 am

Using a Falcon 9 rocket with a first stage making its 15th flight, SpaceX early this morning launched 21 Starlink satellites, lifting off from Vandenberg in California.

The first stage landed successfully on a drone ship in the Pacific. SpaceX now has two first stages that have flown 16 times, and one that has flown 15 times. Those 47 flights like reduced the launch cost of those launches by about 70%. Since no other rocket company can do this, SpaceX can pocket the profits since it isn’t forced to lower prices as much as it would if it had some real competition.

The leaders in the 2023 launch race:

57 SpaceX
36 China

Click for original image.

Axiom announced today that in its most recent round of funding it raised an additional $350 million in private investment capital, almost tripling the private capital it has obtained in total.

Axiom Space announced today that it secured $350 million in its Series-C round of growth funding, lifting the total funds raised to over $505 million from investors and achieving more than $2.2 billion in customer contracts.

To date, Aljazira Capital and Boryung Co., Ltd., have anchored the round, paired with support from an array of diverse backers that include deep-tech venture capital funds and strategic brand partners, positioning Axiom Space as second to SpaceX for the most amount of money raised by a private space company in 2023, based on available pitchbook data.

The press release also reaffirms the company’s planned schedule for its space station project, with the first module launching and attaching to ISS in 2026. The graphic shows the assembly sequence, with the rear docking port the one linked to ISS. When assembly reaches the stage of the fourth image it will then be able to separate from ISS and fly independently in 2031. That last number however is one year later than NASA’s previous predictions for the retirement of ISS, suggesting Axiom knows something NASA has not yet told us.

A Martian wedding cake surrounded by brain terrain

Brain terrain surrounding a Martian wedding cake
Click for original image.

Of all many cool images I’ve posted, today might take the cake (pun intended) for the best illustration of the alien nature of Mars. The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 28, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the scientists simply label as “flow features.”

I personally don’t see any obvious flow features in the full image, unless one wants to call the brain terrain that covers this entire plain a flow feature. Brain terrain is a feature unique to Mars whose origin remains a mystery to geologists. As noted by scientists in captioned MRO image in 2019:

You are staring at one of the unsolved mysteries on Mars. This surface texture of interconnected ridges and troughs, referred to as “brain terrain” is found throughout the mid-latitude regions of Mars.

…This bizarrely textured terrain may be directly related to the water-ice that lies beneath the surface. One hypothesis is that when the buried water-ice sublimates (changes from a solid to a gas), it forms the troughs in the ice. The formation of these features might be an active process that is slowly occurring since HiRISE [MRO’s high resolution camera] has yet to detect significant changes in these terrains.

The wedding cake inside the small crater to the upper right only adds to the alienness of this terrain.

Watch the landing attempt of Chandrayaan-3’s Vikram lander on August 23, 2023

9:39 am


Click for interactive map.

After separating from its Chandrayaan-3 propulsion module on August 17, 2023, India’s Vikram lunar lander has been slowly making orbital adjustments in preparation for its landing attempt on August 23rd.

I have embedded the live stream of that landing attempt below. As it is scheduled for 6:04 pm (India time), in India, in the U.S. that landing will occur in the early morning hours of August 23rd.

Following the failed crash on the Moon of Russia’s lunar lander Luna-25 yesterday, this landing attempt is likely to garner a lot more interest. It is also India’s second attempt, having failed in 2019 when its Vikram lander ran out of fuel before landing and crashed.

China’s Long March 4C rocket places Earth observation satellite into orbit

9:14 am

China yesterday used its Long March 4C rocket to put what that country’s state-run press calls an “Earth observation satellite” into orbit, lifting off from the Jiuquan spaceport in the interior.

No word on whether the rocket’s first stage crash landed near habitable areas, as China’s disposable first stages often do.

The leaders in the 2023 launch race:

56 SpaceX
36 China
11 Russia
6 Rocket Lab
6 India

American private enterprise still leads China in successful launches 64 to 36 in the national rankings, while the entire world combined 64 to 58. SpaceX alone now trails the entire world (excluding American companies) 56 to 58.
