Musk: We will attempt to catch Starship like Superheavy, “hopefully early next year”

10:23 am

According to a tweet by Elon Musk on October 15, 2024, SpaceX is targeting early 2025 for the first attempt to recover Starship after launch, and to do it the same way it recovered Superheavy, by catching it with a set of launch tower chopsticks.

To do this will require getting that second launch tower at Boca Chica operational. It will also require SpaceX to successfully restart Starship’s Raptor engines in space, something it has not yet done. Once this is demonstrated to work, the company would also have to do another orbital test where Starship is put in a full orbit and then de-orbited precisely to a point over the ocean, demonstrating that such a return can next be done reliably over land.

In other words, a tower catch can only happen after at least two more test flights. Thus, to do it early next year means SpaceX will have to establish a test launch pace of a launch every one or two months. This is actually something Musk has said repeatedly he wants to do, but has been stymied repeatedly by FAA red tape from doing it.

I suspect Musk’s tweet is expressing his unstated hope that a Trump victory in November will force the FAA to ease its bureaucratic interference.

Rocket Lab wins launch contract to launch quickly, within two months

10:11 am

Rocket Lab yesterday announced that it has scheduled a new Electron launch for October 19, 2024, based on a contract it signed with a “confidential commercial customer” only two months ago.

The expedited mission will be Rocket Lab’s fastest turnaround to date: from signed contract to launch date in less than two months.

If successfully, it will also be the company’s 12th launch in 2024, completed in the year’s first 10 months. Its previous record for successful launches in a single year, nine, was set in 2022, and that took the entire year to accomplish. Though this record is certainly impressive, it appears at this time that the company will not meet its goal of 20 launches in 2024, though it might not miss it by much.

Scientists: most asteroids come from a limited number of earlier break-ups

10:04 am

According to three different recently published papers (available here, here, and here), the majority of all meteorites hitting the Earth likely came from a limited number of specific past break-ups of larger asteroids.

New studies show that 70% of the 70,000 meteorites that have been found on Earth have come from 3 recent collisions in the main asteroid belt which sits between the orbits of Mars and Jupiter. The collisions occurred 5.8, 7.5 and 40 million years ago, according to the studies. They correspond to 3 young asteroid “families” known as Karin, Koronis and Massalia. These families formed from the destruction of asteroids at least 30km across.

The 70% number comes from data in the last two papers above, while the first paper claims it is more like 80% of all asteroids. The Massalia family is the most dominate, with it estimated to be the source 37% of all meteorites as well as a major impact half a billion years ago.

The first study also found that both Ryugu and Bennu came from the same event and are part of another family of asteroids called Polana.

Sierra Space wins NASA contract to develop trash compactor for use in space

9:47 am

Sierra Space yesterday announced that it has won a NASA contract to develop trash compactor for use in space and test it on ISS by 2026.

The system’s goals will not only be to reduce the volume of waste, but to recover all the water contained within it.

Current primary waste systems in space cannot reclaim water or effectively reduce the volume of trash in a manner necessary for long-term space travel. The TCPS [Sierra’s compactor] is being developed to recover nearly all the water from the trash for additional use. This capability may be vital not only for deep space exploration but also for commercial orbital facilities or extraterrestrial bases. As a stand-alone system, TCPS only requires access to power, data, and air-cooling interfaces and it provides a simple user interface to facilitate crew interactions.

The key to this development is that it isn’t being developed by NASA solely for ISS. Sierra will own the product, and design it to be used on any in-space operation, from space stations to lunar bases.

NASA to phase out its government-built communications satellite constellation, rely on commercial services

9:41 am

Capitalism in space: NASA yesterday announced that beginning on November 8, 2024 it will begin the phase out of its government-built TDRS communications satellite constellation, requiring all future missions to use commercial services for communications and data transmission.

As of Friday, Nov. 8, the agency’s legacy TDRS (Tracking and Data Relay Satellite) system, as part of the Near Space Network, will support only existing missions while new missions will be supported by future commercial services.

…While TDRS will not be accepting new missions, it won’t be retiring immediately. Current TDRS users, like the International Space Station, Hubble Space Telescope, and many other Earth- and universe-observing missions, will still rely on TDRS until the mid-2030s. Each TDRS spacecraft’s retirement will be driven by individual health factors, as the seven active TDRS satellites are expected to decline at variable rates. 

NASA in 2022 already issued contracts to six commercial communication companies to provide these services, Inmarsat, Kuiper Government, SES, SpaceX, Telesat, and Viasat. Yesterday’s annoncement involves NASA’s long term plan to retire the TDRS constellation.

SpaceX sues California Coastal Commission

9:30 am

Wants to be a dictator
Wants to be a dictator

As promised by Elon Musk, SpaceX has now filed suit against California Coastal Commission, and its commissioners, accusing it of violating Musk’s first amendment rights and using its regulatory power against the company simply because those commissioners disagree with Musk’s political positions.

You can read SpaceX’s lawsuit filing here [pdf]. From its introduction:

[The Commission has engaged in naked political discrimination against Plaintiff Space Exploration Technologies Corp. (SpaceX) in violation of the rights of free speech and due process enshrined in the First and Fourteenth Amendments of the United States Constitution. Rarely has a government agency made so clear that it was exceeding its authorized mandate to punish a company for the political views and statements of its largest shareholder and CEO. Second, the Commission is trying to unlawfully regulate space launch programs—which are critical to national security and other national policy objectives—at Vandenberg Space Force Base (the Base), a federal enclave and the world’s second busiest spaceport.

The lawsuit stems from the comments made by the commissioners when then voted against the military’s plan to allow SpaceX to increase its launch rate at Vandenberg spaceport to up to 50 launches per year. In those comments, the commissioners made it clear that the main reason they were voting against the motion was because they were offended by Elon Musk and his political positions, not because the company was doing anything wrong. In fact, the commissioners knew SpaceX was doing nothing wrong. As noted at the first link above:

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.

Spring etch-a-sketch near the Martian south pole

Spring etch-a-sketch near the Martian south pole
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 28, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely as a “terrain sample,” it was likely snapped not as part of any specific research project but to fill a gap in the camera’s schedule so as to maintain its proper temperature.

The camera team tries to find interesting geology when they do this, and are frequently successful. In this case the image shows some truly alien Martian terrain at 77 degrees south latitude, about 475 miles from the south pole.

What are we looking at? I promise you it isn’t the iron filings found inside an Etch-A-Sketch drawing toy. My guess is that the base layer is the light areas, a mixture of ice and debris impregnated with dust and eroded into the unique Martian geological feature dubbed brain terrain. As for the dark lines and splotches, their explanation might lie in the time of year, the spring.

Airbus to eliminate 2,500 jobs in its space and defense divisions

12:00 pm

Airbus has decided that through 2026 it will eliminate 2,500 jobs in its space and defense divisions.

The Airbus cuts come just months after it said in its second-quarter earnings report that the space division was affecting its financial performance. In those earnings, it took a charge of 989 million euros ($1.08 billion) against the space business, relating to an audit of costs in the division and projected lower revenues.

According the company’s press release, the cuts will be targeting what appears to be a bloated management structure.

Intended measures will include creating a more effective and efficient organisational structure for the Division, especially with regard to headquartered functions.

The company does not plan to lay off anyone against their will. Instead, it will work out a buy-out program, the details of which are not yet known, that will encourage employees to leave voluntarily.

The issues here are probably related to the failure of the Ariane-6 rocket, which though now operational is too expensive to compete effectively in the modern launch market. Though it is built by ArianeGroup, a joint partnership of Airbus and Safran, its losses will percolate back to Airbus itself. That the cuts will target upper management also makes sense. Why does Airbus’s space division need a large payroll at its headquarters if it has shifted its space operations to the subsidiary ArianeGroup?
