SpaceX completes static fire test on Starship prototype #8

9:09 am

Capitalism in space: SpaceX last night successfully completed the static fire test on its eighth Starship prototype, for the first time firing three Raptor engines simultanously.

Video of the test, cued to just before ignition, is embedded below the fold.

The company will now install the nosecone on the prototype, repeat this static fire test again in about a week, and then prepare it for its first flight, an expected 50,000 foot hop. I expect that hop to occur in early to mid-November, about the same time the next manned Dragon flight will occur.

The edge of Martian chaos

2:05 pm

Overview map of end of Kasei Valles

For today’s cool image, we are going to start from afar and zoom in, because I think that might be the best way to gain at least a rudimentary understanding of the strange geology visible at this one particular Martian location.

The first image, to the right, is the overview map. The red cross indicates our target, a chaotic canyon that flows into the larger Kasai Valles, one of Mars’ largest and longest canyons and possibly only exceeded in size by Valles Marineris. This part of Kasai is near its end, where it drains out into the vast northern lowland plains of Mars.

The second image, below, comes from the wide angle camera on Mars Reconnaissance Orbiter (MRO).

The big lie of “systematic racism” in America

12:13 pm

In June, shortly after George Floyd met his tragic death while in the hands of arresting police officers, former vice president and Democratic Party presidential candidate Joe Biden was asked by a television reporter, “Do you believe there is systemic racism in law enforcement?” Biden responded as follows:

“Absolutely,” Biden responded. “But it’s not just in law enforcement, it’s across the board. It’s in housing, it’s in education, and it’s in everything we do. It’s real. It’s genuine. It’s serious.”

The absurdity of Biden’s response is immeasurable. What he says here is a lie, a lie so absurd it is both astonishing and horrifying that anyone believes it. There has been no systematic racism in America for generations, and anyone who thinks so is either lying to themselves, or trying to spread lies to others.

The biggest irony is that those who apparently believe this lie the most, our younger college-aged generation, have grown up in a society where for decades blacks with talent and determination have had no problem achieving success in all sorts of business and fields, with some even becoming the dominate figure in their field. (Think of Barack Obama and Oprah Winfrey as only two examples.) They can also marry anyone they want, can go anywhere they want, and achieve anything they want. Nothing stops them but their own limitations.

Russian astronauts repair oxygen regeneration unit

10:26 am

Russian astronauts on ISS have successfully repaired the oxygen regeneration unit on the Zvezda module.

From the TASS article was this additional information:

The Elektron-VM oxygen supply system developed by Russia’s Research and Design Institute of Chemical Machine-Building (NIIChimMash) has been operational aboard the space station since its creation. The system can generate from 25 to 160 liters of oxygen per hour and additionally from 50 to 320 liters of hydrogen per hour. In April 2010, it took the ISS crew several days to fix the broken system.

No word yet on any new information on the “fracture” that is causing the slow leak.

SpaceX launches another 60 Starlink satellites

10:18 am

Capitalism in space: SpaceX today successfully launched another 60 Starlink satellites, raising the constellation to more than 800 satellites.

The first stage successfully landed, for the sixth time, on a drone ship. The company also recovered both fairings, which were making their third flight. With one fairing’s recovery however the net broke on the ship, which might have damaged it this time.

The leaders in the 2020 launch race:

26 China
17 SpaceX
11 Russia
4 ULA
4 Europe (Arianespace)

The U.S. had regained the lead over China, 27 to 26, in the national rankings.

Another high altitude balloon company enters the space tourism market

3:30 pm

Capitalism in space: Another high altitude balloon company, this time from Spain, is now vying for the space tourism market.

EOS-X Space, a Spanish startup, wants to take 10,000 people to the frontier of space within the next 10 years. With EOS-X Space, the journeys won’t be in rockets or ultrasonic planes. They’ll instead take place in a pressurized capsule propelled by a balloon that will rise to an altitude of up to 40 kilometers, or nearly 25 miles.

This means space tourists won’t have to wear a suit for the duration of the trip, nor will they have to do any physical preparation. Depending on the weather, each trip is set to last four or five hours.

They are targeting the same market as the American company Space Perspectives, which hopes to begin flying tourists on its stratospheric balloon, dubbed Neptune, by ’24.

Spaceport America in New Mexico fires its head

3:26 pm

The board of Spaceport America, Virgin Galactic’s launchsite for its SpaceShipTwo suborbital manned spacecraft, yesterday fired its long time Executive Directory Dan Hicks, at the same time governor of New Mexico removed one board member.

Hicks, the spaceport’s CEO since 2016, has been on administrative leave since June while allegations of mismanagement and abuse of authority have been under investigation by the New Mexico State Auditor and the New Mexico Spaceport Authority, the public body governing the spaceport.

The McHard Accounting Consulting firm, a forensic accounting firm based in Albuquerque, conducted an investigation which was then referred to the state auditor. Keyes informed a state legislative committee this summer the allegations included potential criminal activity.

Spaceport American had been made gigantic promises by Richard Branson back in the mid-2000s, including hundreds of tourist flights per year on SpaceShipTwo, all of which would bring lots of cash to the spaceport and to New Mexico. All came to naught. I suspect those failed promises are somehow connected to the accusations here.

Delta 4 Heavy launch now delayed indefinitely due to launchpad issues

3:16 pm

ULA has now delayed indefinitely the launch of a military reconnaissance satellite using its Delta 4 Heavy rocket because of ongoing issues in the swing arms on the launch tower.

According to ULA’s CEO, Tory Bruno:

..ULA was “working through an issue with pad hydraulics” associated with the swing arm retraction system at the Delta 4 launch pad. Three swing arms feeding propellants and conditioned air to the rocket and its satellite payload are designed to retract as the Delta 4-Heavy lifts off.

“Fixing is always easy,” Bruno tweeted. “Making sure something stays fixed takes more work and lots of discipline.”

This launch has been delayed numerous times in the past two months, almost always because of a variety of different problems, most related to the launchpad, with two scrubs occurring as launch aborts at launch. As the article at the link correctly notes,

The repeated problems with different parts of the Delta 4-Heavy’s launch pad have raised questions about aging infrastructure at pad 37B, which was originally built to support Saturn rocket launches in the 1960s, then mothballed until Boeing took over the facility in the 1990s for the Delta 4 program.

Boeing built the towering mobile gantry for the Delta 4 rocket, along with a then-new fixed umbilical tower with huge swing arms designed to pull away from the launcher as it climbs away from the pad.

The age of the launchpad, combined with the expensive complexity of the Delta 4 Heavy that results in very few launches spread over many years, cannot result in reliable operations.

Joshua Wong – The New Politics

6:01 pm

An evening pause: Hat tip Jim Mallamace, who accurately describes this as “a mildly amusing short sci-fi film.”

My thought in watching this short film is that I have been watching and reading sci-fi movies and books about a oppressive future imposed by technology for almost sixty years. All were written as warnings of a future to avoid. Instead, it appears we have taken them all as instruction manuals.

Modern science: Celebrating a “high priestess” instead of data

12:37 pm

The corruption of modern science and our intellectual class was well illustrated today by the following headline and article in the peer review journal Science:

Act now, wait for perfect evidence later, says ‘high priestess’ of U.K. COVID-19 masking campaign

From the article’s lead:

In May, when several prominent U.K. scientists pushed back against a Royal Society report recommending face masks to help control the spread of COVID-19, Trisha Greenhalgh was furious. The scientists argued there was insufficient support in the scientific literature for the efficacy of masks, and the U.K. government, following their lead, declined to mandate masks for the general public.

“The search for perfect evidence may be the enemy of good policy,” Greenhalgh, a physician and expert in health care delivery at the University of Oxford, fumed in the Boston Review. “As with parachutes for jumping out of airplanes, it is time to act without waiting for randomized controlled trial evidence.” [emphasis mine]

The highlighted words have been the typical argument of the global warming crowd for decades. “We can’t wait for evidence! We need to act now before it’s too late!”

Moreover, she — along with the writer of this Science article — also copies another global warming dishonest tactic, posing a false argument by claiming that the opposing scientists requried a “randomized controlled trial” to demonstrate the usefulness of masks. This is an absurd misstatement, as it ignores decades of research that already exists and was referenced by those opposing scientists, that showed that mandating widespread mask use was generally a bad idea, and would accomplish nothing good.
