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

Both side boosters landing during the 1st Falcon Heavy launch

the 1st Falcon Heavy launch

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.”

Conscious Choice cover

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.

Where is China’s Zhurong Mars rover?

2:13 pm

Where is Zhurong?

At this moment we do not have confirmation that China’s rover Zhurong landed safely on Mars. Assuming it did, the mosaic to the right, made from two images from Mars Reconnaissance Orbiter’s (MRO) context camera, shows that landing zone, with the white cross indicating the centerpoint of the suspected landing site, as leaked to the Chinese press back in October 2020.

The red boxes are the only two images released by China that were taken by its Tianwen-1 orbiter of this landing zone. The two white boxes show the areas covered by two of the seven or so photographs taken by MRO’s high resolution camera since that location was revealed. Below is a map showing all the images MRO has taken of this location.

Why no visual confirmation of the landing on Mars of China’s Zhurong rover?

12:03 pm

Despite more than 48 hours having passed since China announced the successful landing of its Zhurong rover on Mars in the northern lowland plain of Utopia Planitia, no images or data of any kind has been released by that nation or its space agency.

It is very possible that this is totally expected, since they have always said they will need about a week of checkouts before they rollled the rover off the lander and begin its operations.

At the same time, China has been very very creative with providing early images for all its planetary missions. For example, within hours of landing they had released images from their Chang’e-5 lunar sample return lander. Similarly, only hours after Chang’e-4 landed on the far side of the Moon with its Yutu-2 rover China released images.

They did the exact same thing when Chang’e-3 landed in 2013 with its Yutu-1 rover.

I can’t imagine they don’t have some cameras on the Mars lander to snap pictures of the horizon or the ground directly below. They might not, but if so the lack would be truly astonishing.

It is also possible China is holding the data close for any number of political reasons, though this doesn’t make much sense since the whole political point of these planetary missions is to sell China to the world.

The more time that passes with no confirmation data, the more it will appear that something is wrong. If this conclusion is incorrect, China needs to act now to dispel these doubts.

Today’s blacklisted American: Space Force officer fired for criticizing Marxism and condemning bigotry

11:12 am

Twitter's idea of debate
Show trials: What America’s Space Force apparently wants.

Blacklists are back and the military’s got ’em: Lt. Col. Matthew Lohmeier, a fourteen year veteran of the Air Force who became one of the first officers in the Space Force, has been fired by his superiors because he wrote a book criticizing Marxism and compounded that sin by repeating the criticisms, along with criticisms of the undeniable bigotry of critical race theory, on a public podcast.

From a military pr officer:

“This decision was based on public comments made by Lt. Col. Lohmeier in a recent podcast,” a Space Force spokesperson said in an email. “Lt. Gen. Whiting has initiated a Command Directed Investigation on whether these comments constituted prohibited partisan political activity.”

Lohmeier’s temporary assignment in the wake of his removal was not immediately clear. [emphasis mine]

In addition, Amazon has decided to shadow ban Lohmeier’s book, Irresistible Revolution.

Irresistible Revolution has debuted in a strong position and as of this writing, it is #2 and #3 in military policy on Amazon, despite the fact that within hours of Lohmeier being relieved of his command, the book was no longer searchable on the publishing giant’s website. Only a direct link to the book’s page works at this time. It is available at Barnes & Nobles and other online booksellers such as Hudson and AbeBooks.

Lohmeier notes that he wrote the book entirely on his own time. He also informed the military of its existence and offered to have them review it before publication. The Pentagon said such a review was not required.

So what exactly did Lohmeier say that made his superior, Lt. Gen. Steven Whiting, believe he was participating in “partisan political activity”? From the Military.com come article:

SpaceX launches 52 Starlink + 2 customer satellites

4:09 pm

Capitalism in space: SpaceX today successfully launched another 52 Starlink satellites along with two smallsat satellites.

They have put just under 1,700 Starlink satellites into orbit. The first stage completed its 8th launch, and the fourth in 2021, according to the SpaceX announcer. Let me repeat that: That’s four launches of the first stage in less than five months. The fairing halves were also flying on their second flight.

The leaders in the 2021 launch race:

15 SpaceX
12 China
7 Russia
2 Rocket Lab

The U.S. now leads China 20 to 12 in the national rankings.

Rocket Lab launch fails

9:22 am

Rocket Lab’s launch yesterday of its Electron rocket failed when the upper stage began tumbling right after stage separation and engine start.

This was the second Electron failure in twenty launches. The last, in July 2020, was also caused by a problem in the upper stage, though far less dramatic. In that case an electric failure caused the upper stage engine to shut down prematurely before it had reached orbit.

Though the launch was a failure, the recovery of the first stage as part of Rocket Lab’s effort to make it reusable appears to be proceeding as planned. According to the company’s statement:

Electron’s first stage safely completed a successful splashdown under parachute and Rocket Lab’s recovery team is working to retrieve the stage from the ocean as planned.

I have embedded below the fold the Rocket Lab live feed, cued to just before the failure. You can see that as soon as the upper stage fires it begins to tumble.

China’s Zhurong rover successfully lands on Mars

10:45 pm

The rover landing site for Tianwen-1's rover

The new colonial movement: China’s today successfully landed its Zhurong rover on the northern lowland plains of Mars dubbed Utopia Planitia.

China’s lander and rover began their descent to the surface at about 4:00 p.m. EDT (2000 GMT) by separating from the Tianwen-1 orbiter, which since March has been used to capture imagery of the targeted landing site for study. An aeroshell protected the stacked probes as they plunged into the atmosphere at 3 miles per second (4.8 km per second), generating tremendous heat in the process.

Once inside the atmosphere, while traveling at supersonic speeds, the spacecraft deployed a 2,150-square-foot (200 sq. meter) parachute to slow its approach to less than 328 feet per second (100 m per second). China based the canopy design on the parachutes it has used on Shenzhou missions to return astronauts to Earth.

Finally, the Tianwen-1 lander fired thrusters similar to the type on China’s Chang’e lunar landers to make the final descent. A laser range finder and a velocity sensor helped guide the craft as it hovered at about 328 feet (100 m) to identify obstacles and measure the slopes of the surface before touching down safely.

We don’t yet know the exact touchdown point. The image above is a mosaic of two wide angle photos from the context camera on Mars Reconnaissance Orbiter (MRO), with the white cross marking the spot previously leaked by the Chinese press as the landing site. The white box shows the area covered by the only high resolution MRO photo, as of October 2020. Since then MRO has taken a number of additional high resolution images of this area. The red boxes are the areas covered by the only two high resolution images released by China from its Tianwen-1 Mars orbiter

Note that the rover is actually not yet on the ground. It still sits on the lander. A ramp will be deployed and it will then roll down on the ground to begin what China says is a planned 90 day mission, with the most important data likely coming from the rover’s ground penetrating radar, looking for underground ice.
