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.

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.

The dim future of SLS indicated at space business symposium

At a symposium in DC yesterday, a panel of past managers — all of whom had been involved in previous government transitions at NASA — attempted to predict what the consequences will be for NASA with the new Trump administration.

Most of the opinions were pure guesses, some better than others. The real moment of truth came when the entire panel was asked to predict the future of SLS and Orion. The question was put forth by one of the panelists, Lori Garver, who had been NASA’s deputy administrator during the Obama administration, and seemed to have the best understanding of how much the arrival of Trump will likely shake things up significantly.

At one point in the discussion, she asked the panel if they thought the Space Launch System and Orion programs would continue in the next administration. None of the panelists raised their hands. [emphasis mine]

Several of these panelists were big supporters of SLS. Their lack of confidence in its future tells us that SLS and Orion no longer have strong political backing in Washington. Both stand on thin ice.

I predict both will be shut down within the next year, before the next Artemis flight, the first to be manned, to be replaced with a entirely different manned space exploratory program to the Moon and Mars. The decision will be a smart one, but tragically late in coming. SLS should have been dumped years ago. If it had, the U.S. effort to return to the Moon would have been better off, moving forward with a better plan years earlier. Instead, this late decision will once again delay any manned lunar missions for years more.

The change however will be good in the long run, because I expect the new program will be better designed, more efficient, cost less, and be able to do what SLS promised but could never deliver. And it will be based on what private enterprise can accomplish, not a government designed behemoth designed mostly as pork.

Firefly raises $175 million in new private investment capital

The rocket startup Firefly has now raised another $175 million of private investment capital, during a new round of funding, on top of another $300 million raised previously.

Firefly Aerospace has raised $175 million in a round led by a new investor to support production of launch vehicles and spacecraft with an increased focus on responsive space capabilities.

The company announced Nov. 12 it raised what it described as an oversubscribed Series D round led by RPM Ventures. Several other existing and new ventures also participated in the round, which values Firefly at more than $2 billion.

That valuation is an increase from the $1.5 billion the company reported in November 2023 when it closed the final tranche of a Series C round. The company did not disclose the size of that earlier round but said then it had raised about $300 million since February 2023.

It appears RPM likes how the company has focused on providing the military launch services, which can also be profitable for private satellite customers. This money will be used to help increase the production of Firefly’s Alpha rocket.

JPL to layoff 5% of its workforce, the third major layoff this year

JPL in California announced today a layoff of 325 workers, about 5% of its workforce, the third major layoff imposed this year.

The JPL press release indicates the layoffs are because of NASA budget cutbacks, but does not provide any specificity. The cause centers mostly around NASA’s decision to pause its Mars Sample Return project, which JPL was leading. From this report:

This is the third round of layoffs at JPL this year, a reduction spurred primarily by major budgetary cuts to the Mars Sample Return mission, which is managed by JPL. NASA directed $310 million this year to the effort to bring Mars rocks back to Earth, a steep drop from the $822.3 million it spent on the program the previous year.

In January, 100 on-site contractors at JPL were let go after NASA instructed the lab to reduce spending in anticipation of a much tighter budget. In February, the lab laid off 530 employees โ€” approximately 8% of its workforce โ€” and another 40 contractors.

It increasingly appears that JPL’s place in the redesigned mission could be significantly reduced.

The press release also makes it sound like these cutbacks are the end of the world. As JPL has mostly functioned for decades as a private institution attached to NASA almost like a government agency, no one there ever expects to get laid off. In the real world however layoffs such as this happen all the time, especially when a company fails to deliver. JPL in recent years has had budget and management problems, epitomized by the problems now seen with that sample return mission, so it should not be surprised by these cutbacks from NASA.

Cargo Dragon docked to ISS boosts station

For the first time a cargo Dragon capsule used its Draco attitude thrusters to test their ability to adjust or raise ISS’s orbit.

NASA and SpaceX monitored operations as the companyโ€™s Dragon spacecraft performed its first demonstration of reboost capabilities for the International Space Station at 12:50 p.m. EST on Friday. The spacecraftโ€™s Draco thrusters adjusted the stationโ€™s orbit through a reboost of altitude by 7/100 of a mile at apogee and 7/10 of a mile at perigee, lasting approximately 12 minutes and 30 seconds.

This posting is late because of my Grand Canyon trip, but I’m posting this now to make sure it is on the webpage. The goal of the test was to prove another American method for adjusting ISS’s orbit, in order to replace the Russian Progress capsules which now do the job. This test proved Dragon’s thrusters can be used for small orbital adjustments, but whether it can do major orbital corrections remains unclear. A previous test using Cygnus had already showed it could do the job.

Polaris completes first inflight ignition of its aerospike engine

In what appears to be a first, Polaris Spaceplane on October 29, 2024 successfully completed the first ever inflight ignition of an aerospike engine, using its Mira-2 unmanned engineering prototype.

Later in the day on 29 October, MIRA II took off from Peenemรผnde Airport on the coast of the Baltic Sea with a takeoff mass of 229 kilograms, which represented a reduced propellant load. The vehicle flew to the ignition point over the Baltic Sea, approximately 3 kilometres away from the ground station, and once there, completed a short three-second burn of its AS-1 aerospike engine. During the short burn, MIRA II experienced an acceleration of 4 m/sยฒ.

According to the company, the engine operated at a reduced chamber pressure during the three-second burn, resulting in a fuel-rich combustion.

There have been several attempts in the past to develop the aerospike engine, none of which ever completed any test flights, as far as I am aware. The concept is that the thrust is released in a string of openings, with only one wall forming the nozzle shape and the atmosphere used to complete the nozzle on the other side. As the atmospheric density changes the nozzle shape thus changes its shape, producing the most efficient thrust throughout the engine’s entire flight.

More test flights will be required before the company will be able to begin work on its full scale Aurora spaceplane.
