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
11 Russia
6 Rocket Lab
6 India

In the national rankings, American private enterprise now leads China in successful launches 65 to 36. It also leads the entire world combined, 65 to 58. SpaceX by itself remains in a neck-in-neck race with the rest of the world (excluding American companies), trailing 57 to 58 in successful launches.

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.

Luna-25 lost after crashing on Moon

9:37 am

During its last major orbital burn, Luna-25’s engines apparently fired for longer than planned so that, instead of placing it into a lower orbit, the spacecraft was de-orbited and sent crashing onto the lunar surface.

The Russian space agency noted that all measures regarding the location of the spacecraft and establishing communications with it on August 19 and 20 yielded zero results. “Preliminary analysis results suggest that a deviation between the actual and calculated parameters of the propulsion maneuver led the Luna-25 spacecraft to enter an undesignated orbit and it ceased to exist following a collision with the surface of the Moon,” Roscosmos stated.

This is a tragedy for Russia, as this mission hoped to re-establish it as one of the major players in the exploration of the solar system. Instead, we once again have a data point suggesting significant quality control problems within Russia’s aerospace industry. Its misplaced focus on providing government jobs rather than actually building and quickly flying spacecraft and rockets results too often in failure.

Luna-25 fails to enter orbit for landing on Moon

12:23 pm

Though it is in lunar orbit, Russia’s Luna-25 lander today was unable to perform an engine burn as planned to place it in its final orbit for landing.

“Today, in accordance with the flight program of the Luna-25 probe, at 2:10 p.m. Moscow time, a command was issued to the probe to enter the pre-landing orbit. During the operation an emergency occurred on the space probe that did not allow it to perform the maneuver in accordance with the required parameters,” Roscosmos said.

Engineers are analyzing the issue, but no other information was released.

This issue could simply be the spacecraft’s computer aborted the engine burn because it sensed something not right, and that after some correction another burn can follow later. Under this circumstance the landing attempt would simply be delayed.

It is also possible something happened during that engine burn, and the spacecraft is either in an incorrect orbit, or might even be lost entirely. Stay tuned.
