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.

Mars’ endless cycles of glacial activity

10:46 am

Overview map

Mars' endless cycles of glacial activity
Click for original image.

While the images being sent to us from Mars Reconnaissance Orbiter (MRO) repeatedly show features that appear convincingly like glaciers, the data is also beginning to tantalize us with evidence of the endless glacial cycles that have occurred on Mars.

The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 27, 2023 by MRO’s high resolution camera. The red dot in the inset of the overview map above shows the location, the western flanks of an apron that surrounds a 3,800-foot-high mesa in the chaos region Deuteronilus Mensae, the western end of the 2,000-mile-long mid-latitude strip of chaos regions I dub glacier country, because every image seems to show some form of glacial feature.

Today’s picture is no different. The apron shown here drops the last 1,000 feet of the mesa’s total 3,800-foot height, during which it shows dozens of what the scientists label “parallel lines.” These lines likely reveal the layers of glacial ice in this apron, with the older layers larger and more extensive. Apparently, with each growth cycle the glacier obtained less snow from the atmosphere, so the more recent layers grew less.

In other words, the amount of water on Mars has been declining with time.

Untangling these numerous layers will undoubtedly give us a remarkably detailed history of Mars entire geological history. Unfortunately, that untangling cannot happen until we have boots on the ground, on Mars, able to drill core samples from many different places.

Commercial spaceport in Australia signs its first launch contract

9:42 am

Australia map showing ELA spaceport location
The red dot marks ELA’s location, on the north coast of Australia.

Australia’s first commercial spaceport, Equatorial Launch Australia (ELA), has signed a multi-launch contract with a South Korean startup rocket company, Innospace, with the first launch targeting April 2025.

Though Innospace successfully launched a suborbital test flight in March, it has not yet launched a rocket to orbit. Meanwhile, ELA is negotiating with a number of other rocket companies, but it also appears it is having problems with the administrative state in the U.S.

The South Korean company is first off the blocks as it is not subject to the strict technological transfer regulations applied by the United States.

[ELA’s CEO Michael] Jones says delays to the signing of a Technological Safeguards Agreement (TSA) between Canberra and Washington is holding up several potential US customers. “We’re still waiting with bated breath for the TSA, despite a bilateral announcement by Biden and Albanese in Japan in early June that the deal was done and dusted,” he explains. “We were all expecting it to be released by the end of the financial year and the process of being endorsed by Parliament begun”.

A pattern of delay and intransigence in Washington, blocking commercial space, does seem to be developing since Joe Biden took over as president.
