Discovery channel to launch contest to fly winner to space

9:19 am

Capitalism in space: The Discovery channel today announced that it is planning a contest where the winner will win an eight-day flight to ISS in partnership with the space tourism company Axiom.

The casting call on Discovery’s website says that eligibility is limited to U.S. residents or citizens, with additional requirements to be disclosed. For now, there are few other details about eligibility for hopeful astronauts applying to the Discovery show, the expected challenges entrants will face and who will serve as judges for the competition, as the series isn’t expected to start filming until next year.

It is so far unclear whether or not eligibility may include people with physical disabilities, but the casting call does include questions about your degree of impairment with physical activities. (The European Space Agency’s current astronaut process is open to candidates with physical disabilities, and the forthcoming Inspiration4 mission includes Hayley Arceneaux, who has a prosthetic limb after childhood bone cancer.)

Discovery said the series will be in eight parts and will chronicle a “grueling” process. “The series will follow each of the contestants competing for the opportunity in a variety of extreme challenges designed to test them on the attributes real astronauts need most, and as they undergo the training necessary to qualify for space flight and life on board the space station,” the channel said in a statement.

It is unclear exactly when this mission will fly, but based on its description and timing I suspect it will not be for several years, and might actually take place after Axiom installs its own module to ISS in ’24.

1st pictures from Zhurong finally released

China today finally released the first images from its Mars rover Zhurong, proving that the rover landed successfully and is operating as planned. The link takes you to the website of the Chinese space agency, in Chinese. This link provides some details in English.

The two images to the right show the front and rear views from Zhurong, sitting on top of its landing. The black & white front view shows the deployed ramps that the rover will roll down when it begins it operational phase. It shows, as expected, the generally flat terrain of the northern lowlands plains of Utopia Planitia. In the distance however there appears to be distinct features, possibly the rim of a small crater. At the moment the exact location of the rover is not known, so no precise map yet exists of its surrounding terrain. This will change in the coming days as both Chinese and American scientists hone in on the rover using orbital images.

The color rear view shows that the rover’s solar panels and high gain antenna have properly deployed. While the design of Zhurong in many ways imitates the two American rovers Spirit and Opportunity (probably because China hacked into the JPL website for several years and downloaded their blueprints), it also includes several upgrades. For example, Zhurong’s solar panels unfold, providing a significantly larger surface area to gather sunlight. Both Spirit and Opportunity were somewhat hampered by the power they could obtain by their smaller solar panels. Both also experienced times when Martian dust on the panels reduced that power. Zhurong’s much larger panels will protect it better from these issues, and could allow it to survive longer on Mars.

China’s Long March 4B rocket launches oceanography satellite

12:46 am

China tonight successfully launched a new oceanography satellite using its Long March 4B rocket, completing a three satellite constellation.

No word on whether the rocket’s first stage landed on any villages in the interior of China.

The leaders in the 2021 launch race:

15 SpaceX
13 China
7 Russia
2 Rocket Lab
2 ULA

The U.S. still leads China 21 to 13 in the national rankings.

Martian mesas made entirely of dry ice!

1:27 pm

Dry ice mesas on Mars
Click for full image.

Time for an especially cool image! The photo to the right, taken on February 13, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and cropped and reduced to post here, shows some mesas on the south polar ice cap of Mars.

What makes those mesas cool (literally and figuratively) is that they are thought to be made up entirely of dry ice, part of the thin but permanent frozen carbon dioxide cap in the south. As explained to me by Shane Byrne of the Lunar and Planetary Lab University of Arizona, who requested this image from MRO,

[These mesas are] unusually thick compared to other dry ice mesas (a common landform in the residual ice cap). I only have the lower resolution laser altimeter data to go off for heights here (we may get a stereo pair next year), but from that it looks like 13 meters thick.

That’s about forty feet high, from base to top. In length, the largest mesa on the left is about a mile long and about 1,500 feet wide, on average. And it is made entirely of dry ice!

The red cross on the map below shows the location of these mesas on the south pole ice cap.

Today’s blacklisted American: New Apple hire fired immediately because other Apple employees considered his writings “unsafe.”

12:28 pm

The Bill of Rights cancelled at Facebook and Instagram
Doesn’t exist at Apple.

They’re coming for you next: Though Apple had actively recruited Antonio García Martínez and had reviewed his past work thoroughly before hiring him, the company fired him almost as soon as he started working for them because some of its other workers had put together a letter calling for his blacklisting because his published writings made them feel “unsafe.”

“Given Mr. García Martínez’s history of publishing overtly racist and sexist remarks,” the letter read, “we are concerned that his presence at Apple will contribute to an unsafe working environment for our colleagues who are at risk of public harassment and private bullying.”

All of this without even a hint that there’s ever been anything like such a problem at any of his workplaces.

The letter above, like the campaign against Martinez by hack press outlets like The Verge, includes a number of slanders and purposely false interpretations of what Martinez had written in his one published book, Chaos Monkeys, available on line from all ebook vendors and described on its Amazon page as

ULA successfully launches military reconnaissance satellite

10:56 am

Screen capture from ULA’s live stream.

Capitalism in space: ULA successfully launched a Space Force military reconnaissance satellite using its Atlas 5 rocket. It also deployed two cubesats.

This was the first Atlas 5 launch in 2021. The satellite has now been deployed into its transfer orbit taking it to its final geosynchronous orbit.

The leaders in the 2021 launch race:

15 SpaceX
12 China
7 Russia
2 Rocket Lab
2 ULA

The U.S. now leads China 21 to 12 in the national rankings. Note also that though we are still six weeks short of the year’s halfway point, the U.S. is already more than halfway to its total from all of 2020, 40 launches. If this pace continues the U.S. has a good chance of reaching launch totals that were only routine during the mid-1960s, at the height of the beginnings of the space race.

NASA gives an American the seat on Dragon flight that it had been holding for Russian

10:15 am

NASA yesterday announced that it has added an American astronaut to the next manned mission to ISS, set for October.

NASA said that Kayla Barron will join the Crew-3 mission, launching on a SpaceX Crew Dragon spacecraft scheduled for launch no earlier than Oct. 23. Barron joins NASA astronauts Raja Chari and Tom Marshburn, and European Space Agency astronaut Matthias Maurer, who had been assigned to Crew-3 last December.

The Crew-3 mission will relieve the Crew-2 astronauts who arrived at the station on another Crew Dragon spacecraft April 24. The four Crew-3 astronauts will remain on the station for a six-month stay.

The space agency had been holding that seat open for a Russian, as part of its long term barter arrangement whereby in exchange for flying Americans on Soyuz capsules, Russia flies Russians on American spacecraft. That arrangement had been used repeatedly when the shuttle was flying, but since its retirement the U.S. has been forced to buy its seats on Soyuz as it had nothing to offer in exchange.

With the arrival of SpaceX’s Dragon capsule however NASA has been trying to get the Russians to renew that arrangement. And though an American, Mark Vande Hei, flew for free on a Soyuz last month, the Russians have as yet refused to assign their own astronaut to this upcoming October flight, despite months of negotiations. It appears NASA decided it could wait no longer, and filled the seat with its own astronaut.

In fact, the announcement by Roscosmos on May 13th that the next two Soyuz launches to ISS will carry two commercial passengers each means that Vande Hei cannot return on a Soyuz until next year. The seat he would have used to come home now must be used by these tourists, meaning his mission will now be extended to last for as much as a full year or more.

Unless of course NASA decides to bring him home on a Dragon capsule instead.

China rolls out rocket for next space station launch

10:00 am

The new colonial movement: On May 15th China rolled out the Long March 7 rocket that on May 20th will carry the first Tianzhou cargo freighter to the already launched core module of its space station.

Tianzhou-2 will carry 4.69 tons of cargo in a pressurized segment and 1.95 tons of propellant, according to the China Manned Space Agency (CMSA).

Meanwhile, the core stage, dubbed Tianhe, has successfully completed its on-orbit checkouts and has placed itself in the right orbit for the arrival of Tianzhou.

If all goes right with this cargo mission, China is targeting a June launch for the station’s first three-man crew, who will attempt to stay at the station for three months.

Do not expect much information to be released by China during these missions. Like the Soviet Union of old, and as they have been doing routinely since their space program began to gear up in the past decade, they will only make periodic terse announcements, all of which will contain only the most superficial of information. Only much later will more be learned, usually many years after the fact when its news value has vanished and it only concerns historians and space buffs.

Flash! SpaceX to use a NEW Falcon 9 1st stage!

9:48 am

Capitalism in space: For the first time in since September 2020, SpaceX has delivered a new Falcon 9 1st stage to its Florida launch site in preparation for launch.

This new stage will be used on the June 3rd launch of a cargo Dragon freighter to ISS.

What is remarkable about this story is that it is news that SpaceX is using a new first stage. Not only have all of their fifteen launches in 2021 lifted off with used boosters, since November 2020 they have completed nineteen launches using only used boosters.

That’s 19 launches in only six months, all with previously flown boosters!

During that time the company’s Falcon rocket division has apparently dedicated its time in upgrading and building new Falcon Heavy 1st stage boosters, in preparation for the first Falcon Heavy launches since June 2019, set for July and October later this year. I suspect the focus has been an effort to upgrade the core booster so that it will be successfully recovered this time, something that did not occur on two of the first three Falcon Heavy launches in 2018 and 2019..

Texas: No masks, no restrictions, now no COVID deaths!

3:24 pm

Surprise! Surprise! Two months after lifting business restrictions and mask mandates, Texas reported yesterday no deaths linked to COVID.

Once again the fear-mongers were wrong. Biden called the officials in both Texas and Mississippi “neanderthals” for their decisions to end lockdowns and mask requirements. Others predicted a wave of deaths that would boggle the mind.

Instead, cases of COVID dropped quickly, to actually reach zero for the first time in fourteen months. Though I am sure there will be new coronavirus cases and deaths, that the numbers dropped after removing the stupid lockdowns and mask mandates is just another illustration of how failed a policy those lockdowns and mask mandates were.

Nor is any of this a surprise to anyone who has read this website for the past year. I have been saying from day one that the lockdowns were a terrible mistake, and that the mask mandates were not only useless but possibly very counter-productive. As another writer noted today, “The Neanderthals were right.”
