Russia launches another 36 OneWeb satellites

8:37 am

A Russian Soyuz-2 rocket today successfully launched 36 more OneWeb satellites, raising the total of the satellite constellation in orbit to 358.

The launch was from Russia’s new spaceport Vostochny. As with all launches from Russia, the expendable first stage core and strap-ons landed inside Russia within designated drop zones. And as usual, no word from Russia on whether they landed on anyone’s head.

The leaders in the 2021 launch race:

34 China
23 SpaceX
17 Russia
4 Northrop Grumman

The U.S. still leads China in the national rankings, 35 to 34. With launches scheduled by both countries (two by the U.S. and one by China) over the next three days, these numbers will continue upward.

Webb telescope finally arrives at launch site in French Guiana

2:54 pm

Webb deployment

After almost twenty years of construction (a decade behind schedule) and a cost of $10 billion, ($9.5 billion over budget), the James Webb Space Telescope today arrived at the processing facility at Arianespace’s French Guiana spaceport, where it will be prepared for a December 18, 2021 launch on an Ariane 5 rocket.

Once launched the telescope, which is not a replacement for Hubble because it observes in the infrared (not optical) and is optimized for deep space cosmology, will take two weeks to reach its orbital position about a million miles from Earth, as shown in the graphic.

Let us all cross our fingers and toes that it all works as designed, for if it doesn’t this will be the biggest failure ever in the history of NASA.

Astronaut blood samples suggest long-term exposure to weightlessness causes brain damage

2:10 pm

New research comparing blood samples taken from five Russian astronauts before and after long term missions to ISS suggests that weightlessness can cause brain damage.

Published in JAMA Neurology, the new research looked at five male Russian cosmonauts. Each spent an average of 169 days in space. Blood samples were taken from each subject before leaving Earth, and then at three points after returning.

Five different blood-based biomarkers were measured, each known to correlate with some kind of brain damage. Three biomarkers in particular were found to be significantly elevated after the cosmonauts returned to Earth – neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and a specific type of amyloid beta protein.

The researchers hypothesize the increases in NfL and GFAP levels may indicate a type of neurodegeneration called axonal disintegration. Elevated NfL levels are currently being investigated as a way of detecting the earliest stages of brain damage associated with Alzheimer’s disease.

It must be emphasized that the research did not find brain damage, only data within the blood samples that is often associated with brain damage. More research is required to determine if these biomarkers indicate the same thing in space as they do on Earth.

Today’s blacklisted American: Brownstone Institute blackballed by LinkedIn for associating with famed Harvard epidemiologist

11:12 am

They’re coming for you next: The non-profit Brownstone Institute, founded in 2021 to provide an outlet for educated dissent on science and economic issues, has found itself repeatedly censored by LinkedIn in the past two weeks because one of its founders is famed Harvard epidemiologist Martin Kulldorff.

Brownstone Institute: Censored

If you are a regular reader of this column you might remember Kulldorff’s name. He was blacklisted by the CDC, Twitter, and LinkedIn in late August because he dissents from the oppressive lockdown policies those organizations advocate. He was also one of the leading authors of the Great Barrington Declaration [also available here a pdf], which strongly opposes the policies of lockdowns, mandates, and the other totalitarian actions taken by governments since 2020, and instead calls for the more traditional (and successful) “focused” approach for dealing with epidemics and diseases: Protect the vulnerable (the old and sick) from the disease while letting everyone else (the young and healthy) live normal lives and thus get infected quickly, become immune, and thus squelch off the virus.

Kulldorff is also one of the world’s preeminent experts on vaccine safety and “helped develop the CDC’s current system for monitoring potential vaccine risks.”

Anyway, it appears that on October 1st, LinkedIn suddenly discovered that Kulldorff was one of the senior scholars at the Brownstone Institute, and began deleting the institute’s posts.

Australia to build unmanned lunar rover for NASA

7:06 am

NASA and Australia have signed a deal whereby Australia will provide an unmanned lunar rover on which NASA will put its science instruments, with the package taken to the Moon by a commercial lander.

As part of the agreement, a consortium of Australian businesses and research organizations will develop a small rover that can operate on the lunar surface. The rover would have the ability to pick up and transfer lunar regolith (broken rock and dust) to a NASA-operated in-situ resource utilization (ISRU) system on a commercial lunar lander. Such a rover could fly to the Moon as early as 2026.

While this agreement helps widen the competition in the commercial unmanned planetary aerospace industry, it does so by helping the industry of another country. This policy fits the general philosophy of the Democratic Party and the Biden administration, which generally focuses on aiding other countries before the U.S.

Watching the New Shepard suborbital flight with William Shatner

10:44 pm

I have embedded the live stream of the Blue Origin suborbital flight today of its New Shepard spacecraft, carrying four passengers including William Shatner.

The launch is presently scheduled for 7 am (Pacific). The live stream will start about 5:30 am (Pacific).

As I have noted previously, the announcers for Blue Origin tend to blather quite a bit, hyping the situation to a point of nausea. Hopefully during the flight they will shut up and allow the voices of the passengers to take center stage.

I meanwhile will be on the road during the flight. I will try to post updates as well as my normal news stories, but both might have to wait until I return home in the early afternoon. Regardless, the live stream is below for you to enjoy.

Dusty chaos in Martian canyons

1:37 pm

Outcrops in dusty chaos on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on May 30, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the dusty dry floor of the chaos region of rough terrain in a side canyon of Valles Marineris, near its outlet. The color strip and the bright outcrops suggest that this terrain contains interesting minerals and resources. To determine exactly what those materials are however requires more information not available in this photo.

This ancient chaos terrain is the leftover eroded sea floor of a intermittent inland sea, leftover water from the catastrophic floods that are theorized to have flowed out of Valles Marineris and carved its gigantic canyons.

The overview map below shows this hypothesized sea.

Today’s blacklisted American: Trump’s former lawyer and anyone associated with him shunned and censored

12:20 pm

Today's modern witch hunt
The witchhunt against Trump lawyer John Eastman continues.

Blacklists are back and the Democrats have got ’em: For the crime of representing President Donald Trump during the post-election fervor from November 2020 to January 2021, John Eastman has not only been fired as a teacher by Chapman university back in January, more than 250 professors who belong to the American Political Science Association (APSA) have now petitioned that organization to blacklist and censor both Eastman as well as anyone associated with him.

A September 23 letter, signed by over 250 professors and graduate students, accused Eastman of being part of an “attempted coup.” … David Karpf, a professor at George Washington University, organized the letter. “John Eastman has violated our discipline’s professional ethics by participating in the dangerous attempt to overturn the institution of electoral democracy in the United States,” the political scientists wrote.

The letter then demanded that the APSA “strip John Eastman of APSA membership” as well as sever all ties with those supporting him.

This last demand by these professors forced the APSA to kick out of its convention the live presentations by the Clairmont Institute because Eastman was giving two of those presentations.

Shetland spaceport gets 10-year launch contract from new British rocket company

8:50 am

Capitalism in space: The new spaceport in Shetland, Scotland, has signed a 10-year launch contract from the new British rocket company, Skyrora.

Rocket company Skyrora has agreed a multi-launch deal with the SaxaVord spaceport on Unst, the most northerly of the Shetland Islands, as it moves closer to launching its XL rocket in 2022. This is the first agreement Skyrora has made with a Scottish Spaceport. If successful, this could be the first rocket to go to space from the UK.

The deal with SaxaVord [the new name for the Shetland spaceport] will run for the next decade, giving Skyrora the ability to build towards its target of 16 launches a year by 2030.

The XL rocket is designed to launch smallsats, and will compete with companies like Astra and Rocket Lab. If Skyrora is success, it will not only be the first rocket to launch from the UK, it will be the first British-built rocket to launch since October 1971.
