  • ESA touts its plans to build a low cost, super heavy-lift reusable rocket
    The space agency asked two European rocket companies to propose concepts, from which ESA will then decide what to do. Or to put it another way, ESA is still designing and owning the rocket instead of getting the product from the private sector. This rocket will therefore be the same kind of failure that Ariane-6 has been, expensive, inefficient, and uncompetitive.

Boxwork in the dry Martian tropics

Boxwork on Mars
Click for original image.

Cool image time! The picture to the right, cropped and enhanced to post here, was taken on July 17, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as boxwork, a pattern of intersecting straight ridges criss-crossing each other in a generally random manner.

The ridges themselves are very small, only a few feet high. To make them more visible I have purposely cropped this section without reducing its resolution. I have also increased the contrast.

What caused them? According to this paper [pdf] about similar boxwork found on Mount Sharp in Gale Crater, the boxwork “formed when cements filled existing pore spaces and fractures in fractured rock, and these cements were left as topographic ridges after erosion.”

In other words, the surface hardened, then fractured. Later more resistent material, likely lava, filled the cracks. When erosion later stripped the top surface away, the lava was more resistent and so became the ridges we now see.

NASA reveals that it and Russia disagree about the danger posed by the airleak on ISS

Figure 3 from IG report
Figure 3 from September Inspector General report, annotated by me to show Zvezda location.

In a public session yesterday by a NASA commission focused on accessing the safety condition of ISS, officials revealed that the commission and Russia disagree about the root causes behind the airleak and cracks in the docking section of the Zvezda module on the Russian half of ISS, as well as the risk of a catastrophic failure. According to the commission’s head, former astronaut Bob Cabana.

The Russian position is that the most probable cause of the PrK cracks is high cyclic fatigue caused by micro vibrations. NASA believes the PrK cracks are likely multi-causal including pressure and mechanical stress, residual stress, material properties and environmental exposures.

The Russians believe that continued operations are safe, but they can’t prove that to our satisfaction. The U.S. believes that it’s not safe, but we can’t prove that to Russian satisfaction that that’s the case. So while the Russian team continues to search for and seal the leaks, it does not believe catastrophic disintegration of the PrK is realistic and NASA has expressed concerns about structural integrity of the PrK and the possibility of a catastrophic failure.

Because of this disagreement American astronauts now close the hatch between the Russian and American halves of ISS whenever a docking to Zvezda is taking place, and apparently keep that hatch closed until unloading of the docked spacecraft is complete. The Russians in turn only open the hatch to the docking section of Zvezda when they need to load or unload material into the freighter docked there, and coordinate with American astronauts whenever they do so.

Engineers from the two nations continue to discuss the issue, and hope to result their disagreement and come up with a joint plan.

Ultimately, this issue indicates the certain end of ISS in the near future, and adds ugency to the need to get some of those commercial space stations operating in orbit.

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

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.

China and SpaceX complete morning launches

Both China and SpaceX today successfully completed morning launches.

First China launched an environmental satellite to study “ocean salinity,” its Long March 4B rocket lifting off from its Taiyuan spaceport in northeast China.

No word on where the rocket’s lower stages crashed inside China. All use very toxic hypergolic fuels, which can literally dissolve your skin.

Next SpaceX completed another launch of 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its eighteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

114 SpaceX
52 China
13 Russia
12 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 132 to 77, while SpaceX by itself leads the entire world, including American companies, 114 to 95.

A Climber’s Perspective – Stacking of a 490′ Self-Supporting Tower via helicopter

An evening pause: The tower is in Watts, Oklahoma. When the lineman looks to his right he is looking at the helicopter, which for the first few minutes, before it rises above the horizon, is difficult to see.

Hat tip Wayne DeVette.

Major court decision could invalidate many federal environmental regulations

In what could be a major legal ruling [pdf], a two-judge decision this week in the DC Circuit Court ruled that the White House Council on Environmental Quality (CEQ), which has for years imposed environmental rules on other federal agencies based on the National Environmental Policy Act (NEPA), does not have the statutory authority to do so, thus invalidating every regulation so imposed.

All three members of the three-judge panel agreed that the Agencies acted arbitrarily and capriciously in [in this particular case]. However, before reaching that conclusion, the majority analyzed whether the CEQ regulations the Agencies followed in adopting the plan were valid, an argument not raised by any of the parties. The majority held, sua sponte, that because there is no statute stating or suggesting that US Congress has empowered the CEQ to issue rules binding on other agencies, the CEQ has no lawful authority to promulgate such regulations.

…Although this decision does not explicitly vacate any action taken by the CEQ, it does establish a precedent that CEQ rules lack statutory authorization, and therefore that other agency actions taken under the CEQ framework are at risk of being vacated. If this decision is not overturned by the full appellate court sitting en banc or by the US Supreme Court, it has the potential to completely change the landscape of NEPA review.

The case is complicated, partly because the Byzantine nature of the federal bureaucracy and the many agencies involved. (It is almost as if these agencies created that complexity to confuse and protect themselves.)

The heart of the decision is that CEQ was apparently first created as an “advisory” body to help other federal agencies follow the intent of NEPA in their own rule-making, but instead soon became a “regulatory” body whose rulings other agencies were required to follow. As that authority was never given it by Congress, CEQ exceeded its authority by making its rulings mandatory.

This court decision will likely leave many agencies on their own in establishing environmental regulations, based on NEPA. However, even that regulatory ability faces limitations, based on the Supreme Court’s recent Chevron decision, which said that government agencies do not have right to promulgate new regulations that are not specifically described in congressional law.

In other words, Chevron says that the bureaucracy cannot make things up, based on its own vague opinions.

The trend of all these court rulings appears aimed at limiting the power of the federal bureaucracy. It will however take some time to determine how much that power is limited, as lawsuits begin to percolate through the courts. If there are lot of lawsuits (which does appear to be happening) we should therefore expect that power to be limited significanly.

Another cool hiking location on Mars

Overview map

Another cool hiking location on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 10, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

My reason to posting this I admit is selfish and tourist-oriented. This narrow ridge, about a mile long and about 300 to 600 feet high, appeals directly to my hiking passions. A trail along its length would provide any hiker some really spectactular views.

The scientists took the picture because of the geology. The white dot on the overview map above marks the location, a short channel dubbed Daga Vallis that connects two major canyons in the eastern part of Valles Marineris, the largest known canyon system in the solar system. This ridge and several nearby parallel ridges were apparently made of something, possibly lava, that was resistent to the theorized ancient catastrophic floods that scientists presently believe carved out these channels and canyons.

In the inset the dotted line indicates one possible hiking trail route that travels the full length of the ridge but then heads south to continue along the rim of a 1,200-foot-high cliff face. For future Martian colonists, I offer this site as a great place to set up a bed-and-breakfast, surrounded by many potential hikes of incredible stark beauty.

Rocket Lab announces first launch contract for its new Neutron rocket

Though the press release was lacking in many details, Rocket Lab yesterday announced the signing of its first launch contract for its new Neutron rocket, scheduled to make its first orbital test launch in 2025.

Under the contract, Rocket Lab will launch two dedicated missions on Neutron starting from mid-2026. The missions will launch from Rocket Lab Launch Complex 3 on Wallops Island, Virginia. The launch service agreement for these missions signifies the beginning of a productive collaboration that could see Neutron deploy the entire constellation.

The press release did not name the satellite constellation, or the company building it. Rocket Lab’s founder and CEO, Peter Beck, was quoted as follows: “Constellation companies and government satellite operators are desperate for a break in the launch monopoly.” [emphasis mine] That launch monopoly is clearly SpaceX, and Beck was positioning Rocket Lab with Neutron as the company to provide an alternative.

The announcement as well as the company’s third quarter report caused a 45% surge in its stock price.
