A detailed review of SLS’s present launch status

Link here. The article provides a detailed look at the engine controllers in the former shuttle engines that SLS is using on its core first stage, including some details about the failed unit and the issues involved in replacing it.

I found this historical data in the article most interesting:

The first attempt to launch Orbiter Atlantis and the STS-43 Shuttle vehicle was scrubbed before dawn on July 24, 1991, when the primary computer, DCU A, failed while propellants were being used loaded into the External Tank. … As a result, the launch was scrubbed to allow replacement of the controller, and the launch was rescheduled for August 1, 1991. The failure analysis of the controller revealed a broken blind lap solder joint connection of the bit jumper to the half stack, which is not a generic design problem.”

According to contemporaneous Shuttle Status Reports issued by NASA Public Affairs at KSC in late July, 1991, after the launch was scrubbed and the External Tank was drained and inerted, access to the engine area for maintenance was established on July 26. The broken engine controller was removed, and a new one was installed on July 27, followed by testing to verify the new controller on July 28; the three-day countdown was started over from the top on July 29 for the next launch attempt on the morning of August 1.

It took NASA less than a week to replace an engine controller in 1991. Now, it appears it might take NASA several months, including testing, to do the same thing on SLS. Moreover, the article suggests that there are other subcontractors and organizations (such as the range safety) that are also having trouble being ready for the presently scheduled mid-February launch.

All in all, this report suggests that SLS will not launch in February, will be delayed until April, with a strong chance that even that April date might not be met.

The report also illustrates the sluggish manner in which NASA operates today. Nothing is done with any speed. No task is done in one day if it can take a week. This is bad management, and also a very dangerous way to operate, as it actually encourages sloppiness because no one is under any pressure to work hard. The result has been endless niggling failures, each of which delays things interminably.

Local judge blocks Camden spacesport

Capitalism in space? Almost immediately after the FAA last week issued a launch license for the proposed commercial spaceport in Camden, Georgia, a judge in the state courts issued an injunction blocking it.

The order and request for an interlocutory injunction was filed last week by Camden residents James Goodman and Paul Harris. Camden County Superior Court Judge Stephen G. Scarlett granted the restraining order on Tuesday and scheduled a hearing on the injunction for Jan. 5.

This order prevents the spaceport, being developed by the county itself, from purchasing any additional land for the project.

Meanwhile, a petition to force a referendum for or against the land purchase has obtained enough signatures. They needed 3,400 signatures — 10% of the registered voters of Camden county — and obtained 3,800. Those signatures are presently being verified by the county probate court, which has until mid-February to complete its work. If a special election is then called, it likely won’t occur before the middle of 2022.

It is perfectly legitimate for the citizens of the county to express their opposition to such a project. And if in a special election a majority disapprove, then it is perfectly correct for the county’s effort to be shut down.

This opposition however gives us a peek into the modern culture of America, hostile to innovation and new businesses, and willing to use the government aggressively to prevent it. Whether that hostility is felt by the majority in Camden County is at present unknown, though the success of the petition suggests it is. The special election will tell us.

I predict however that if the special election comes down in favor of the spaceport, the opposition will not accept that result, and will then move to find other legalities that they can enlist the government to use to block the project.

This project is beginning to remind me of Hawaii and the Thirty Meter Telescope, which has been effectively blocked from construction by what appears to be a very small number of radical protesters.

Identity of $28 million bidder for New Shepard flight revealed

Capitalism in space: The person who bid $28 million to win a seat on the first suborbital flight of Blue Origin’s New Shepard spacecraft has now revealed himself.

Justin Sun, the founder and CEO of the blockchain platform Tron, announced today (Dec. 22) that he’s the person who paid $28 million for a seat aboard Blue Origin’s first crewed spaceflight. That mission launched on July 20, carrying Blue Origin founder Jeff Bezos and three other people to suborbital space on the company’s New Shepard spacecraft. The then-unnamed auction winner was not among them, however, remaining groundbound due to scheduling conflicts, Blue Origin representatives said at the time.

But it turns out that Sun’s spaceflight dreams were just deferred, not dashed. The 31-year-old entrepreneur said today that he plans to fly on a New Shepard mission next year, along with five other “space warriors” that he will nominate.

Sun outlined what he’s looking for in a Twitter thread today. One crewmate nominee will be “a prominent figure in the crypto[currency] world,” he said. Another will be a Tron community member “with a strong passion for space,” and another will be a tech entrepreneur. The fourth and fifth nominees will be an artist and a celebrity, respectively.

It is unclear if Blue Origin is giving him six seats for his $28 million, or if Sun is paying additional money. At this time Bezos’ company has not revealed anywhere what it is actually charging for tickets.

FAA’s approval of SpaceX’s Starship operations delayed at least a month

The FAA has now had to delay the final approval of its environmental reassessment of SpaceX’s Starship facility and operations at Boca Chica for at least one month because NOAA has refused to approve the plan.

That puts NOAA’s generic review of Rocket Landing and Launches back to at least the end of January, with the much more complex and contentious USFWS [Fish and Wildlife] review also pending (this one is habitat and species review of impacts to bird and wildlife populations specific to Boca Chica).

The earliest approval by the FAA (which again, is far from a sure thing) should be projected into February. And the actual launch license process can’t be started until then. March is absolutely the earliest even the giddiest optimist could expect for Starship’s Maiden Orbital Flight.

It appears that the bureaucrats in NOAA are hostile to the launch site, and are looking for reasons, mostly environmental, to either block it or slow it down.

It also appears that a second Department of the Interior agency must sign off, and it is also hostile.

Based on this story, it looks like Starship’s first orbital flight will not happen until the latter half of ’22, if then. Nor can we expect any help from the Biden administration. Unlike Trump, the Democrats now running the executive branch of government do not like private enterprise and business, and generally look for excuses to regulate and even block it, especially if they think there is the slightest chance it might harm some formerly unknown species somewhere.

This is America today, no longer free. Rather than you making the decision freely, as an American citizen, un-elected federal government officials now decide whether you can do anything, or not.

Japan’s H-2A rocket launches communications satellite

Japan today successfully launched a commercial communications satellite using its Mitsubishi-built H-2A rocket.

This was Japan’s third and likely last launch in 2021. Since 2018 its numbers have been low, ranging from 2 to 4, so this total matches that pace. It is an embarrassment for Japan, however, when compared to China and SpaceX.

The leaders in the 2021 launch race remain unchanged:

48 China
31 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

The U.S. and China remain tied at 48 in the national rankings. This was the 128th successful launch in 2021, making it the second most active year in the history of rocketry, exceeded only by 1975, when there were 132 successful launches, 98 of which were by the Soviet Union, with the bulk of these being short term low orbit spy satellites.

Today’s blacklisted American: College football coach fired for putting up hand-written sign saying “All lives matter.”

Opinions that are banned at Illinois State University
Opinions banned by Illinois State University’s football team.

They’re coming for you next: Kurt Beathard, an offensive coordinator coach for the Illinois State University football team, was fired because he replaced an official school poster that had been pinned to his office door that specifically endorsed the Black Lives Matter movement with a hand-written sign that said, “All lives matter to our Lord and Savior Jesus Christ.”

[Head coach Brock Spack] asked Beathard to remove the poster, which the offensive coordinator did. “Meanwhile, another coach who wanted to replace Beathard as offensive coordinator had taken a picture of Beathard’s poster and shared it with the football players,” the lawsuit alleges. Apparently, the picture upset some of the football players.”

“On 9/1/20, some of the football players boycotted practice,” the lawsuit said. “Spack came to Beathard’s office and informed him that it looked like Lyons [another coach he had gotten in trouble for making fun of Black Lives Matters] was going to keep his job but that Beathard was in trouble over the poster.”

The next day, he lost his job because Spack did not “like the direction of the offense.”

Beathard, who had worked for 25 years as a football coach, has filed a lawsuit [pdf] against both Spack and Lyons in the federal courts, claiming that they fired him “for one reason and one reason only: He did not toe the party line regarding the Black Lives Matter organization.” The lawsuit also notes that his firing violated the school’s own policy, which states:.

Astronomers detect 70 to 170 free floating exoplanets

The uncertainty of science: Astronomers today announced that they think they have detected from 70 to 170 exoplanets in a nearby star-forming region that are apparently free-floating, unattached to any star or solar system.

The astronomers also combined the vast number of images available in public astronomical archives with the new deep wide-field observations obtained with the best infrared and optical telescopes on the ground and in space. Using over 80,000 wide-field images adding up to around 100 terabytes and spanning 20 years, they identified at least 70, and up to as many as 170 of these Jupiter-sized planets, as members of the Upper Scorpius association among the background stars and galaxies.

If confirmed, this discovery more than doubles the number of free-floating planets known.

The discovery was made by first using the motion of the stars to pinpoint which ones belonged to the Upper Scorpius star-forming region. The astronomers then compared this data with past archival telescopic images.

Though intriguing, a great deal of skepticism of this discovery is required. The press release is very vague about some points. For example, no explanation is given on how they measured the mass of these objects to determine they were Jupiter-sized.

The barren rocky terrain in the mountains of Gale Crater

Curiosity's view looking south towards Mt Sharp, Sol 3333, December 21, 2021

Cool image time! Curiosity yesterday used its navigation cameras to take a panorama of the view inside Maria Gordon Notch. The mosaic above, created from five images taken by the right navigation camera, shows the view looking south and uphill towards Mount Sharp. The heights of the nearest four hills are likely ranging from 30 to 100 feet.

The red dotted line indicates the planned route out of Gordon Notch and up onto the Greenheugh Pediment. If you click on the panorama to look at the full resolution version, you will see that the exit route looks extemely rough, possibly too rough for Curiosity to handle. How the science team handles this issue will be fascinating to watch in the coming weeks.

The map to the right gives us an overview. The white line is Curiosity’s actual travels. The red dotted line marks the planned route. The yellow lines indicate the area covered by the panorama above.

The most striking feature of this Martian terrain is its stark barrenness. All one can see in all directions are rocks and inanimate geology. There is no life, none at all. On Earth it is practically impossible to find any mountainous spot as barren as this, even in the most extreme and hostile environments.

As I’ve said before, Mars is strange, Mars is wonderful, and above all, Mars is alien.

SpaceX begins testing of launch procedures for Superheavy prototype #4

Capitalism in space: SpaceX began this week the testing of the fueling and launch procedures it will follow for launching the first orbital Superheavy, prototype #4, presently mounted on the orbital launchpad at Boca Chica.

On December 17th, SpaceX subjected Super Heavy B4 to a cryogenic proof test about twice as ambitious as B3’s, filling the booster maybe a sixth of the way with a few hundred tons of liquid nitrogen (LN2). What isn’t clear is if that test also raised the booster’s propellant tanks to flight pressures (6-8 bar or 90-115 psi). If Booster 4 did reach those pressures, the test is even more significant – partially proving that the rocket is ready for flight. On December 21st, SpaceX performed a similar series of cryogenic tests, again partially filling Booster 4 with about the same amount of liquid nitrogen but doing so two or three times in a row. Again, the Super Heavy survived the several-hour ordeal without any obvious issues. Still, a number of additional tests – some even more important – are still in front of SpaceX and Super Heavy B4.

The most obvious is simple enough: SpaceX needs to fully fill a Super Heavy booster for the first time. Depending on the storage situation, that process will likely begin by filling Booster 4 with about 2500 tons (5.5M lb) of liquid nitrogen (LN2) – about two-thirds full. If SpaceX also temporarily fills one of the orbital tank farm’s liquid oxygen (LOx) or methane (LCH4) tanks with nitrogen, it could fully load Booster 4 with around 3500 tons (7.7M lb) of nitrogen. At least according to SpaceX’s own website, that’s about the same weight as the propellant (3400t/7.5M lb) Super Heavy is designed to lift off with. If that full cryoproof goes well, SpaceX will then likely perform one or several wet dress rehearsals, ultimately filling Booster 4 with approximately 2900 tons (6.4M lb) of cryogenic oxygen and 500 tons (1.1M lb) of cryogenic methane.

At some point the company will need to not only fill the booster, it will need to do at least one static fire test of its 29 engines. If all goes well, SpaceX will then mount Starship on top, with the first orbital flight to follow. Musk has said they are aiming for a January launch, but no one should be surprised if it slips to February.
