Russian astronauts repair oxygen regeneration unit
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.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
SpaceX launches another 60 Starlink satellites
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
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.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.
Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.
Spaceport America in New Mexico fires its head
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
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
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
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.

Chang’e-4 and Yutu-2 awake for 23rd lunar day on far side of the Moon
The new colonial movement: China’s Chang’e-4 lander and Yutu-2 rover have both been reactivated for their 23rd lunar day on far side of the Moon.
Yutu 2 is set to continue its journey northwest from the landing site and will target a roughly 12-inch (30 centimeters) rock on the rim of a nearby crater for analysis with a spectrometer. The rover has used that instrument to analyze a range of specimens in Von Kármán crater, notably causing a stir when it discovered an impact melt breccia initially described as “gel-like.”
It is the hope of the Chinese scientists that this rock will be ejected material from that crater and will have come from the lunar interior.
Also, though you need to read Chinese to understand how to access it, the project has released to the public another batch of data from both spacecraft.
ArianeGroup completes testing of all three Ariane 6 rocket engines
Capitalism in space: ArianeGroup, the joint private partnership that is building Europe’s new Ariane 6 rocket, has successfully completed all testing of the three different engines the rocket will use.
The first stage has a core engine with side strap-on solid rocket motors, while the upper stage has a different engine entirely. All three have now passed qualification tests, allowing full design and construction of the rocket itself.
Old launch tower burns down at Firefliy launchpad at Vandenberg
Capitalism in space: Apparently workers dismantling the old launch tower at Firefliy’s new launchpad at Vandenberg started a fire that burned the tower down.
A photo showing the former Delta II rocket’s Space Launch Complex-2 facility with flames and a huge column of black smoke rising from the distinctive blue tower began circulating on social media sites on Thursday night.
The launch site, most recently used for liftoffs of United Launch Alliance’s Delta II rockets, has been handed over to Texas-based Firefly Aerospace, which is developing a new family of rockets as an economical way to carry small- to medium-sized satellites into space.
The firm has a long-term lease to use the site with hopes of saving money by using some of the existing facilities. Firefly has plans to dismantle the historic tower, and a contractor armed with welding equipment reportedly sparked the blaze Thursday.
No word yet on whether this fire will delay Firefly’s planned first launch in the spring.
Leak on ISS traced to “fracture”
Not good news: According the Russian news source TASS, Russian astronauts have pinpointed the location of the slow leak on ISS to ” a fracture in the intersection compartment of the Russian Zvezda module.”
The astronaut also called it a “scratch,” which means the fracture is not yet confirmed. They will do more testing to find out if this is the leak source in the coming days.
If it is a fracture, the ramifications could be very serious. It appears the “intersection compartment” is the area where the aft docking port is located, which is also the area where many Progress freighters have docked in the twenty years since Zvezda was launched. Thus, this could be a stress fracture that can only get bigger with time. Its location might also preclude further dockings at this port, limiting arrivals of future Progress cargo ships.
Fun fact: They pinpointed this location using a floating tea bag.
The tea bag’s sway in zero gravity conditions towards the air leak overboard the space station was registered by cameras, the cosmonaut said. “We believe that we have really identified the probable leakage area. We have distributed a tea bag [in the Zvezda module] before closing the transfer chamber,” Ivanishin said.
The tea bag’s movement was recorded, the Russian cosmonaut said.
