Caving in remote Nevada

1:01 pm

I am leaving today for a four day caving expedition in the remote mountains of Nevada. Thus, there will be little added to the webpage until I return late Monday. I will also not be around to moderate comments. For those new people who post comments please forgive me. Be patient. I will get to it when I get home.

I hope my readers have a great Labor Day weekend. Get out, see friends, go sightseeing, have a great time to celebrate the end of summer. And above all, don’t do what the CDC is demanding, to stay home if you are not vaccinated and even if you are, to wear a mask, maybe two or three, all the time, even when outdoors by yourself. Ignore such idiocy.

Use your common sense instead. Be brave. Be free. And above all, pursue your happiness fully, with joy.

House committee votes to postpone move of Space Force HQ to Alabama

11:28 am

The House Armed Services committee voted yesterday to postpone the proposed establishment of the Space Force’s headquarters in Alabama.

The House Armed Services Committee on Thursday passed, with bipartisan agreement, Colorado Springs U.S. Rep. Doug Lamborn’s amendment to the Fiscal Year 2022’s National Defense Authorization Act — an amendment that would prevent the move of the command to Huntsville, Ala., and work leading up to it, until after the Government Accountability Office and the Department of Defense Office of Inspector General complete their reviews of the decision.

Results of the GAO review, currently underway, are expected to be released in March, Chuck Young, managing director of public affairs for the agency, told The Gazette on Thursday.

This congressional action is not a surprise. The vested interests in Colorado, where a great bulk of the present military space operations are based, were not going to take the shift to Alabama lying down.

Perseverance’s 2nd drill attempt to get sample appears successful

11:18 am

It appears that Perseverance’s second drill attempt on Mars has successfully obtained sample material in its core.

Data received late Sept. 1 from NASA’s Perseverance rover indicate the team has achieved its goal of successfully coring a Mars rock. The initial images downlinked after the historic event show an intact sample present in the tube after coring. However, additional images taken after the arm completed sample acquisition were inconclusive due to poor sunlight conditions. Another round of images with better lighting will be taken before the sample processing continues.

Once they know for sure if they have a sample, they will store it and then move on, heading to the area that Ingenuity scouted for them in mid-August.

FAA grounds Virgin Galactic pending investigationn

10:58 am

Probably in response to the revelation of the flight issue, not an actual safety issue, the FAA has grounded Virgin Galactic from any further flights pending the resolution of the investigation of the July flight, which drifted out of its planned flight path due to high winds.

This will likely delay their planned next manned flight, which had been tentatively scheduled for September-October.

Today’s blacklisted American: Whites to be segregated at American University

10:29 am

The Civil Rights Act of 1964: repealed at American University in DC.
The Civil Rights Act of 1964: Doesn’t exist at American University in DC.

“Segregation today, segregation tomorrow, segregation forever!” American University in Washington, D.C., has now instituted a policy segregating students by race in a course on racism, with the segregation specifically designed to give minorities a “safe space.”

According to The Eagle, the university added a Black affinity course section to AUx2, a class where students learn about “race, social identity, and structures of power.” In the course, students will “evaluate how racism intersects with other systems of oppression.”

The student newspaper states that all-Black sections of the course began during the spring 2020 semester, an addition that had been considered for a few years. “We’ve definitely heard from Black students and other students of color that the material can be a lot for them because it is part of their lived experiences,” Izzi Stern, the AUx program manager told the student newspaper. “And we wanted to create a space where they could be together in community and have an overall positive experience with the course.”

The problem Starship poses to NASA and Congress

8:30 am

An interesting essay published earlier this week in The Space Review raises the coming dilemma that both NASA and Congress will soon have to face once Starship is operational and launching large cargoes and crews to orbit, both near Earth and to the Moon.

That dilemma: What do about SLS and Lunar Gateway once it becomes ridiculously obvious that they are inferior vessels for future space travel?

I think this quote from the article more than any illustrates the reality that these government officials will soon have to deal with in some manner:

[When] the Lunar Starship ever docks with Gateway, the size comparison with Gateway will appear silly and beg the question as to whether Gateway is actually necessary. Does this even make sense? Couldn’t two Starships simply dock with each other and transfer propellant from one to another. Is there really a need for a middleman?

The author, Doug Plata, also notes other contrasts that will make SLS and Lunar Gateway look absurd, such as when two Starships begin transferring fuel in orbit or when a Starship launches 400 satellites in one go, or when a private Starship mission circles the Moon and returns to Earth for later reuse.

All of these scenarios are actually being planned, with the first something NASA itself is paying for, since the lunar landing Starship will dock with Lunar Gateway to pick up and drop off its passengers for the Moon.

The bottom line for Plata is that the federal government needs to stop wasting money on bad programs like SLS and Lunar Gateway and switch its focus to buying products from commercial sources like SpaceX. They will get far more bang for the buck, while actually getting something accomplished in space.

Though he uses different words, and has the advantage of recent events to reference, Plata is essentially repeating my recommendations from my 2017 policy paper, Capitalism in Space [free pdf]. Plata draws as his proof for his argument the recent developments with Starship. I drew as my proof a comparison between SLS and what private commercial space was doing for NASA, as starkly illustrated by this one table:

The cost difference between SLS and private space

The government has got to stop trying to build things, as it does an abysmal job. It instead must buy what it needs from private commercial vendors who know how to do it and have proven they can do it well.

If the government does this, will not only save money, it will fuel an American renaissance in space. As we see already beginning to see happen now in rocketry and the unmanned lunar landing business.

Firefly first launch attempt fails after liftoff, shortly before stage separation

7:11 pm

Alpha rocket exploding
Screen capture from Everyday Astronaut live stream.

Capitalism in space: Firefly’s first attempt to launch its Alpha rocket to orbit failed at T+2:30 minutes, shortly after it went supersonic and just before first stage engine cut-off and stage separation.

The screen capture to the right shows that explosion.

Lift-off procedures went very well, though the rocket itself appeared to reach supersonic speeds later than their timeline predicted, suggesting it was underpowered.

In fact, the whole operation reminded me of SpaceX’s early attempts to launch its Falcon-1 rocket. Just as happened in one of those early SpaceX launches, there was a launch abort at liftoff, the launch team quickly figured out what happened, recycled the rocket, and successfully lifted off an hour later. Kudos to that team!

The failure is unfortunate, but to repeat the cliche, this is rocket science. They will try again.

A peanut-shaped crater in the northern plains of Mars

1:21 pm

Context camera image of peanut-shaped crater
Click for full image.

Cool image time! The photo to the right, rotated, cropped and reduced to post here, was taken in May 2008 by the wide angle context camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists have since labeled a “peanut-shaped crater.”

What caused this unusual shape? The obvious and most likely explanation is that this was a double impact that occurred simultaneously. Imagine the ground being hit either by an asteroid with two lobes or by two similar-sized asteroids falling side-by-side.

Fast forward thirteen years to 2021. In the fifteen years since 2006 when MRO begin science operations in orbit around Mars no high resolution images were taken of this crater. Finally, on July 30, 2021, scientists finally decided to take a high resolution image of this crater’s western half. You can see that image below, rotated, cropped, and reduced to post here.

Today’s blacklisted American: Lyft driver fired because his radio was tuned to a black conservative

11:33 am

No freedom of speech allowed by Lyft!
No freedom of speech allowed at Lyft!

The new dark age of silencing: A driver has been fired by Lyft because a passenger complained that he was listening to a racist on the radio, when in fact his radio was tuned to a black conservative.

Ryan Alexander, who had been a Lyft driver for years, tells “The Dan O’Donnell Show” that a Lyft representative told him during a phone call Saturday that his account was suspended because he had been listening to “racist talk radio programming,” a violation of the app’s terms of service.

Alexander says he was listening to former Milwaukee County Sheriff David Clarke fill in for Mark Belling during the “Mark Belling Late Afternoon Show” Thursday evening when a passenger took exception to the discussion Clarke was having about Black Lives Matter and abortion rates in the African-American community.

“She called Clarke trash, slammed the door to my car when she got out, and specifically referenced abortion which Clarke did talk about briefly while she was in the car,” Alexander says.

During the portion of the program that the passenger heard, Clarke, who is Black, expressed the opinion that the Black Lives Matter organization did not truly care about Black lives because it was not upset about the rate of abortions among Black mothers.

The troubled politics of ground-based astronomy

10:54 am

Link here. The article outlines the politics and negotiations now going on during the writing of the next astronomy decadal survey, the document American astronomers have published every decade since the 1960s to provide the science agencies in the federal government guidance on how to spend the taxpayers’ money on the next decade’s astronomy projects.

The focus is on the problems now faced by the two big American ground-based telescopes, the Thirty Meter Telescope (TMT) and the Giant Magellan Telescope (GMT).

The future of the Giant Magellan Telescope (GMT) and the Thirty Meter Telescope (TMT) likely depends on whether the survey recommends that NSF spend what sources put at $1.8 billion to support a recently forged partnership between the projects. If it does, other proposals could lose out, such as a ­continent-spanning radio array and detectors for neutrinos and other cosmic particles.

While some astronomers are pushing for this $1.8 billion bailout to save both, others are arguing the money can be better spent elsewhere. There is also a third option, not mentioned, which would be to abandon one of these telescopes and instead build just one.

The story is focused entirely on ground-based astronomy, which is remarkably very near-sighted for scientists whose job it is to see a far as possible. The future of astronomy is in space, and to not consider that alternative in this discussion means you aren’t considering all your options. For $1.8 billion, using private rockets and competitive construction approaches, I strongly believe a very large optical telescope could be launched that would provide far more cutting edge astronomy than any larger ground-based telescope. Hubble has proven that endlessly for the past thirty years.

Prototype of reusable suborbital spaceplane from new startup completes five flights

10:40 am

Capitalism in space: Another rocket startup company, Dawn Aerospace, has completed a five flight test program of a prototype of its proposed reusable suborbital spaceplane, dubbed Aurora.

Dawn Aerospace has successfully completed five test flights of its uncrewed Mk-II Aurora suborbital spaceplane in the skies over Glentanner Aerodrome on New Zealand’s South Island. The flights were conducted by the New Zealand-Dutch space transportation company from July 28 to 30, 2021 at altitudes of up to 3,400 feet (1,036 m), with the prototype airframe fitted with surrogate jet engines.

The three-days of test flights to assess the airframe and avionics of the aircraft took place under a certificate issued to Dawn by the New Zealand Civil Aviation Authority (CAA), which allowed the Mk-II Aurora to operate from conventional airports without airspace restrictions after ground tests were completed.

The company claims this is a demonstrator for their fullscale two-stage-to orbit version that will take off from a runway and then launch small satellites into orbit.

Looks impressive, but my impression of this prototype is that it is a small scale model, only slightly more sophisticated and larger than a model airplane. That impression is reinforced by the video at the link, which provides no visible markers to judge size.

This company needs to get a lot more done if it wants to compete in this new market.
