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
Just a reminder that I will be doing a long appearance on The Space Show tonight with David Livingston, beginning at 7 pm (Pacific).
As usual I beg my readers to call in. The show is always more interesting when people call.
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.
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.
A detailed update on the work being done by NASA and Boeing engineers to prepare SLS for its first unmanned test launch suggests that though a March launch is still the target, it is likely to be delayed.
The update at the link is very thorough, and outlines a large number of tests that need to be done to get this very cumbersome and complicated rocket ready for launch. They are just about done with the prep work for the core stage, and are now shifting to final testing of the upper stage, followed by some countdown sequence testing and a test of the flight termination system. In addition there are a number of other tests they wish to perform, all of which will take time.
Once these are done they will be ready to roll the rocket out to the launchpad for a final dress rehearsal countdown — dubbed the Wet Dress Rehearsal (WDR), now scheduled for mid- to late-February.
NASA will not set a launch date until after the WDR is completed and they can factor in any additional tasks with already-known work. “We’ve continually said that until we get through WDR we won’t set a launch date, so us getting out in mid-February for WDR allows them to look at March and April as opportunities,” Lanham said.
“I really can’t put my finger on it again until we come back from WDR and see if we have any issues there that we’ve got to go correct.” After the WDR test, the vehicle and Mobile Launcher will be rolled back to the VAB for final pre-launch maintenance and servicing.
Some have said the earliest realistic launch date is May, with the mid-summer more likely. We shall have to wait and see.
The uncertainty of science: In reviewing data from Curiosity, scientists have detected a faint enrichment on ridge tops in Gale Crater of the carbon isotope carbon-12, normally associated with life on Earth because it is easier for life to process than the heavier carbon-13 isotope.
In order to explain this enrichment, the scientists have concocted several complicated explanations, all of which seem unlikely because of their complexity. The explanations that include life require a series several precise steps to get the enrichment limited to only high ridges. Another that doesn’t involve life requires the solar system to pass through an interstellar cloud.
One proposed explanation is simpler however, and does not require ancient microbes or interstellar clouds.
More prosaically, a few studies suggest UV rays can generate the signal without help from biology at all. UV can react with carbon dioxide—which makes up 96% of the martian atmosphere—to produce carbon monoxide that is enriched in carbon-12. Yuichiro Ueno, a planetary scientist at the Tokyo Institute of Technology, says he has recently confirmed the process can occur in unpublished lab results. “The reported carbon isotope ratios are exactly what I have expected,” he says.
Though this explanation must explain why they have seen the enrichment only at high points, it is straight forward and fits all the present data we presently have of Mars
All in all, the data is tantalizing but hardly a indicator that Mars once had life. There is too much uncertainty. We do not yet know enough about Mars’ geological and climate history to come to any consensus on an explanation.
According to unnamed sources in Japan’s space agency JAXA, the first launch of its new H3 rocket, presently scheduled for the end of March ’22, will be delayed by as much as a year because of “defects” in the rocket’s engine.
…the discovery of defects forced the Japan Aerospace Exploration Agency (JAXA) to delay it a second time as it remains unclear by when the vehicle’s engine can be redesigned and produced, the sources said Monday.
Some people in the government expressed concerns over the postponement being potentially prolonged, the sources said.
…In May 2020, a test conducted on the H3 rocket’s main engine found holes on the wall of a combustion chamber and a crack on a turbine that feeds fuel to the chamber, prompting the agency to announce the first delay.
Since then, JAXA has reviewed its design and has been reassembling the rocket at Tanegashima Space Center in Kagoshima Prefecture, from where the rocket is planned to lift off.
None of this has as yet been officially announced. If true, this is a serious blow to Japan’s space effort, which has not been very competitive anyway in the global launch industry. The older H2 rocket in use now is very expensive, so that it has garnered few customers outside of the Japanese government. The new H3 was supposed cost less, but it is entirely expendable, so it can’t compete with the reusable rockets of SpaceX, Blue Origin, or Rocket Lab.
It is also apparently being designed and controlled by JAXA, not Mitsubishi, the prime contractor. Government-run programs nowadays routinely experience endless delays and cost overruns, and the H3 project appears to be more of the same.
Parents and state school boards should return the favor, and get out.
Because of a letter [pdf] it sent to the Justice Department suggesting that protesting parents were akin to “domestic terrorists,” the National School Board Association (NSBA) now faces “total collapse,” with nineteen state school board organizations exiting the association, along with 6 members of its 19-person executive board.
More information here, including this quote:
Until this fall, the National School Boards Association was a noncontroversial, bipartisan lobby group. Then its leaders wrote President Biden a letter. It alleged that the threatening and aggressive acts against school board members across the country might be a form of “domestic terrorism” and asked for federal law enforcement intervention.
Now, the association is at risk of total collapse.
…Nineteen mostly GOP-led states have withdrawn from the association or promised to when this year’s membership expires, and six members of what was a 19-person board have left. Several states are discussing forming an alternative association for school boards. A new executive director of the National School Boards Association (NSBA) is working to save the organization, lobbying individual states to reconsider, but so far he has not persuaded any of them to change their minds.
After studying more than 200 samples from ISS brought back to Russia, researchers have identified more than 20 types of microorganisms that make their home on ISS, including some pathogens and fungi.
The habitat of the module and the entire Russian segment of the ISS is an environmental niche home to bacteria and microscopic fungi, the materials suggest. “These microorganisms use the station’s decorative-finishing and design materials as their basic habitat,” according to the materials.
The experiment aboard the ISS involved taking samples and delivering them to Earth in descent modules. In the course of three years, over 200 samples were taken, with bacteria discovered in 34% and fungi in 3% of them. “In 5% of the samples with the presence of bacterial microflora and in 100% of the samples with the presence of fungal microflora, the standard indicator regulated by SSP 50260 NORD was exceeded,” the materials say.
The fungi indicate mold, a long known problem on manned space stations first identified by the Russians on their Salyut stations in the ’70s and ’80s. The pathogens do not appear to be harmful, or else the astronauts would have experienced sicknesses. No such sicknesses have been reported, though they might have occurred but have not been released publicly due to medical privacy concerns.
The new colonial movement: China yesterday completed its first launch in 2022, using its Long March 2D rocket to launch a military test satellite into orbit.
No word on where the first stage crashed in the interior of China, or whether it used parachutes or grid fins to control its landing.
The 2022 launch race:
2 SpaceX
1 Virgin Orbit
1 China
These numbers should change later today, as SpaceX has a Falcon 9 Starlink launch scheduled. UPDATE: The SpaceX Starlink launch has been delayed one day to tomorrow.
Capitalism in space: Stratolaunch today successfully completed the third test flight of its giant Roc airplane, now being optimized to provide a test bed for launching hypersonic test vehicles.
Today’s flight was conducted from California’s Mojave Air and Space Port and lasted four hours and 23 minutes. It came nearly three years after Roc’s first aerlal test, and almost a year after the second flight. The outing’s main objective was to evaluate the airplane’s performance and handling characteristics at increased altitude, and to retract and extend the left mid-main landing gear.
Stratolaunch said Roc reached an altitude of 23,500 feet at an indicated air speed of 180 knots (207 mph), besting the previous flight test’s maximum altitude of 14,000 feet. Before landing, the plane’s crew conducted a couple of close approaches for testing purposes.
The company plans about six to eight more Roc test flights leading up to the first test flights of its hypersonic Talon-A test vehicle, of which Stratolaunch is presently developing two.
I have embedded below the fold the video of the flight, cued about one hour twelve minutes after the start of the live stream to the moment Roc takes off. Those geeks in my readership might want to go back to the beginning to hear the full almost six-hour-long broadcast. My impression is that Stratolaunch provided some excellent announcers to provide technical details describing what is happening.

The Perseverance science team yesterday outlined the first steps in their plan to remove pieces of debris that had fallen into the core sample bit storage carousel, as shown by the picture to the right, and thus prevents them from storing further core samples.
First they have taken pictures of an area of the ground below the rover to establish a baseline. Then,
With this below-chassis, preliminary imaging, in hand, the team [will return] the remaining contents of Sample Tube 261 (our latest cored-rock sample) back to its planet of origin. Although this scenario was never designed or planned for prior to launch, it turns out dumping a core from an open tube is a fairly straightforward process (at least during Earth testing). We sent commands up yesterday, and later on today the rover’s robotic arm will simply point the open end of the sample tube toward the surface of Mars and let gravity do the rest.
This maneuver will tell them exactly how much material broke off the core when some pieces of it dropped into the carousel.
Next, on January 18th, they will have the bit carousel perform two short rotations, the first short and the second longer, to shift the debris in the carousel and get more information about it. Some might drop out with this maneuver, so they are also going to take more ground pictures to see if any did.
They have not yet outlined the next steps in this removal procedure, though they have said the need for this procedure was anticipated when the rover was designed. Thus they must know what those steps will be, but are likely holding off outlining them because they might need to revise their actions depending on what they learn in the next few days.
