Two images taken by one of Perseverance’s cameras and downloaded today appear to show that the bits of debris from the rover’s most recent core sample that had fallen into the sample storage carousel have been dislodged and are now gone.

Those images are above, placed side by side. They were taken a little over an hour apart on January 18, 2022, probably before and after the rover completed two short rotations of the carousel, as planned.

The first image on the left, taken at 12:12:47 local solar time, shows the two small pieces sitting near the bottom inside of the sample storage holder. The second image on the right, taken at 13:20:40 local solar time, shows both pieces gone. There also appears to be less small rubble on the small platform just below this point.

The science team will next take pictures of the ground below, comparing those with pictures taken before the rotations, to see if they can spot this debris and confirm it is completely clear of the rover.

If the debris is gone, as these images suggest, Perseverance will be able to drill another core sample at this location and store it as planned. Expect an announcement by tomorrow or the next day providing more details of this success.

NASA: Russian anti-satellite test in November doubled the threat to ISS

9:17 am

According to a presentation by a NASA official at a conference today, further tracking of the debris from the Russian anti-satellite test on November 15, 2021 suggests that it has doubled the overall chance of a debris collision with ISS.

NASA ISS Program Director Robyn Gatens told a NASA advisory committee today that the November 15, 2021 Russian ASAT test forced the Expedition 66 crew to implement safe haven procedures, closing hatches to parts of the ISS and sheltering in the Soyuz and Crew Dragon spacecraft that could return them to Earth if worse came to worse.

Russia denied the test imperiled the crew, but Gatens said the threat of a piece of debris penetrating the ISS now has doubled to one chance in 25,000-33,000 orbits, versus one in 50,000 orbits prior to the test. The ISS does about 6,000 orbits a year.

It should be noted that, according to these numbers, the overall threat seems quite manageable. Nonetheless, the Russian anti-sat test was entirely irresponsible, especially because it targeted a defunct satellite in an orbit slightly higher than ISS, which means its debris will over time move into ISS’s orbit. The test also violated the Outer Space Treaty, which Russia has signed, which requires all signatories to control what they do in space so that it does not threaten either the persons or property of anyone else.

Chinese pseudo-company preparing first launch of methane-fueled rocket

9:07 am

The Chinese pseudo-private company, Landspace, is apparently prepping its new launchpad and Zhuque-2 rocket for launch in one of China’s interior spaceports.

Satellite imagery and deleted social media postings indicate that work is progressing on a new complex for facilitating methane-liquid oxygen launch vehicles at Jiuquan Satellite Launch Center in northwest China. Timelapse and high resolution satellite imagery show the development near the national Jiuquan center in the Gobi Desert and suggest the presence of a Zhuque-2 test article. A recent, now-deleted article indicates a new flame trench has been completed at Jiuquan.

The article at the link also cites statements by the company’s CEO in November, where he claimed they would launch in the first quarter of ’22. If successful, it would be the first orbital launch of a methane-fueled rocket, beating out both SpaceX’s Starship and Blue Origin’s New Glenn.

The article also says that the company is working on making the first stage reusable, which makes sense in that it will launch from inside China and that first stage if expendable will crash uncontrolled on Chinese territory. A second Chinese pseudo-company, iSpace, also claims it will begin hop tests of its own reusable rocket later this year.

For new readers: I call these companies pseudo because they really are not independent entities, as private companies are in the west. China’s government since 2014 has allowed private investors to create these companies and for the companies to compete against each other for government business, but none of them do anything without the full supervision of the Chinese government. Most have completed their first launches using solid rockets, technology almost always reserved for military use. None could have done so without that government permission and control.

The strategy here of China’s government is nonetheless smart, as the policy is creating competition and thus some innovation within its aerospace industry. The top-down control however will likely prevent these companies from doing anything truly different. Instead, they are apparently latching onto the new ideas, such as methane-fueled rockets and vertically landing first stages, that they have seen demonstrated by the truly independent private companies in the west.

Israel approves Artemis Accords

8:51 am

The Israeli government has apparently agreed to sign the American-led Artemis Accords, making it the fifteenth nation to do so.

While Israel’s foreign ministry has not released an official statement on the issue, local media reports said a signing ceremony involving NASA Administrator Bill Nelson and Israel Space Agency Director-General Uri Oron is expected the week of Jan. 23. ISA will host the 17th Ramon International Space Conference on Jan. 25 as part of Israel’s Space Week.

Once Israel officially signs, the full list of signatures will be as follows: Australia, Brazil, Canada, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Poland, South Korea, the United Kingdom, the United Arab Emirates, Ukraine, and the United States.

Since the accords are designed to encourage private enterprise and private property rights in space, both Russia and China oppose them. The lack of both France and Germany to sign at this point suggests the politicians presently in charge of those capitalist countries are reconsidering their commitment to free enterprise.

Russian astronauts locate another leak on Zvezda

8:44 am

According to Russia’s state-run TASS press, Russian astronauts have located what it calls “the last air leak” on the Zvezda module of ISS.

Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov discovered the last air leak location in the International Space Station’s Zvezda module, Roscosmos spokesman Dmitry Strugovets said Tuesday, adding that the leak will be eliminated after special equipment is delivered to the station.

Like most of the other leaks previously found, this one was located in the aft transition chamber where the Zvezda docking port is located, once again suggesting that these leaks are the result of stress fractures caused by age and the more than a hundred dockings that have occurred there since Zvezda was launched more than twenty years ago.

The Russians’ belief that no more leaks will be found is probably based on their decision to reduce, even cease the use of this port. The new Prichal docking hub, which two Russians today are doing a spacewalk to finalize its integration with the station, makes the shuttering of Zvezda’s port possible.

At the same time, the existence of numerous stress fractures in an ISS module is not something to be dismissed lightly, as the TASS article attempts to do. It is akin to cracks in the hull of a submarine, and I don’t know anyone who would be willing to send such a vessel deep underwater.

Boeing and NASA still aiming for a May launch of unmanned Starliner test demo

7:58 pm

Capitalism in space: Boeing and NASA are still targeting a May launch of Starliner’s unmanned test demo flight to ISS, delayed since August because of a valve issue in the service module.

Though they think they have identified and fixed that sticky valve problem, they have also decided to replace the service module for the demo flight, using the module originally planned for the first manned flight that will follow.

SpaceX launches another 49 Starlink satellites

7:14 pm

Capitalism in space: SpaceX tonight used its Falcon 9 rocket to launch 49 Starlink satellites into orbit.

The first stage successfully landed on a drone ship in the Atlantic Ocean, completing its 10th flight. SpaceX now has three four first stages that have completed at least ten flights. (The correction comes from a comment by one of my readers below.)

The 2022 launch race:

3 SpaceX
1 Virgin Orbit
1 China

Pushback: New VA Attorney General shows Republicans the right way to fight the left

12:50 pm

The way it has been for decades
The way it has been for decades

All around us the oppressive leftists of the Democratic Party are in control. They dominate the mainstream media, the education and science communities, the bureaucracy, the major social media companies, and the entertainment industry. That monolith of top-down rule now imposes its will everywhere, blacklisting and destroying anyone who dares dissent from its agenda.

For decades these intolerant socialists and communists and hate-filled bigots have steadily gained more and more control and power because no one would truly resist them. Time after time they would do something egregious and never face any consequences. For example, in 1999 a DC bureaucrat was forced to resign because he used the word “niggardly,” properly describing how the political world was sometimes cheap and miserly for the wrong reasons. Several ignorant co-workers accused him falsely of using a racial slur, and DC mayor, Democrat Anthony Williams, quickly forced the man to resign. Shortly thereafter Williams realized his error and arranged for the man’s rehiring, but never did anything to discipline the illiterate fools who caused the furor.

Republicans in this matter are far worse. » Read more

Launch of Kickstarter campaign for Pioneer game delayed till Feb 1

9:58 am

Lunar colony, 2173
From the proposed Pioneer video game: a lunar base in 2173,
part of the independent nation, United Lunar.

Because of a number of issues related to marketing, Aaron Jenkin yesterday made the decision to delay slightly the start of the Kickstarter campaign to raise funds for developing his video game based on my science fiction book, Pioneer.

Instead of starting today, Aaron has shifted the date back two weeks to February 1st. From the project’s newsletter, just sent out to those who have subscribed:

To be blunt, we’ve had a surprisingly difficult time in the past few weeks getting the word out about our campaign. And I can tell from looking at the results of our efforts so far, we need to grind away a little longer to solidify our success. With that said, we’ve updated Mr. Zimmerman on where we stand, and we’ve plotted the course that we’ll take over the next two weeks to accomplish our mission.

For a number of reasons, Aaron felt he needed another two weeks to ramp up the marketing campaign. While this means his campaign for funds will coincide with my annual February fund-raising campaign for Behind the Black, we decided to go ahead anyway, figuring the synergy of both might work to our advantage, making 2+2=6.

If you, as a fan of my writing, are thinking of donating to this video game project, I strongly urge you to subscribe to the newsletter. You can do so at the game’s webpage, PioneerSpaceGame.com. Aaron uses the subscription numbers as a guide to measure interest.

Philippino presidential candidate meets with SpaceX officials

9:35 am

SpaceX officials have held a virtual meeting with two senators from the Philippines, one of which is running for president, to discuss allowing Starlink service in their country as well as the establishment of a launch site.

TOP executives of SpaceX met with Senators Emmanuel “Manny” Pacquiao and Aquilino “Koko” Pimentel 3rd to discuss the use of low-orbit satellites to provide cheap internet to the Philippines. SpaceX is a space exploration company owned by technology magnate and billionaire Elon Musk.

During the virtual meeting on Saturday, the SpaceX executives also talked about the possibility of setting up a spaceship launch pad in the Philippines.

Pacquiao also proposed projects for Musk’s other companies, Tesla and Boring. He seems enthusiastic about bringing SpaceX to the Philippines. The odds right now of him becoming president however is not great, according to recent polling. This meeting with SpaceX was clearly an effort by him to garner attention and increase his poll numbers.
