SpaceX begins construction of Starship launchpad in Florida

9:48 am

Capitalism in space: Elon Musk yesterday announced that SpaceX has begun the construction of a Starship launchpad at its facility at Cape Canaveral, though no launch scheduled was revealed.

Musk implied that the Starship orbital launchpad is being built at Launch complex 39A. If so, it will pose some scheduling issues for SpaceX, as the company also uses that site for Falcon 9 and Falcon Heavy launches. In fact, it is the only one it uses for Falcon Heavy.

NASA buys more Dragon manned flights

9:41 am

Capitalism in space: To give it some coverage because of continuing delays in Boeing’s Starliner manned capsule, NASA announced yesterday that it has awarded SpaceX contracts for three more manned Dragon manned flights to ISS.

NASA issued a contract notification announcing its plans to issue a sole-source award to SpaceX for three missions. Those missions would be in addition to the six “post-certification missions,” or PCMs, that SpaceX won as part of its $2.6 billion Commercial Crew Transportation Capability (CCtCap) contract in 2014. The announcement did not state the price of those three new missions.

This is money that would have gone to Boeing, if it had gotten its act together and gotten Starliner flying on schedule. Instead, SpaceX is making the profits.

There has been no updates from Boeing since October on the valve issue that now stalls Starliner. While Boeing claims it is aiming for an unmanned demo flight to ISS in early ’22, this remains entirely speculative at this moment.

BE-4 engine delayed until ’22

9:36 am

Capitalism in space: The CEO of ULA, Tory Bruno, admitted yesterday that the first production versions of Blue Origin’s BE-4 rocket engine, required for his company’s new Vulcan rocket, will not be delivered until until early ’22.

Bruno had previously said he expected the engines in late 2021 but on Friday he confirmed the BE-4s will not arrive until early 2022. “I was hoping to get those engines for Christmas. I had giant stockings at home waiting for them,” Bruno quipped in the CNBC interview.

“I’ll say it’s taking them a little longer to fabricate my production engines. They’re in the factory now being built at Blue Origin,” said Bruno. “The COVID epidemic has affected them and their supply chain and it’s just taking a little bit longer, but they’re doing very, very well,” he added. “There’s been no problems with them and in fact, we’re doing the final testing, or what we call certification testing. And that is just going really, really well.”

It appears that Blue Origin is dealing with the difficulties of production, not design, at this point, the same kind of issue that SpaceX recently revealed with its Raptor engine. Blue Origin needs to be able to manufacture these engines at a somewhat high pace, as both ULA’s Vulcan and Blue Origin’s New Glenn rocket use it. It appears that in designing it Blue Origin didn’t think about the manufacturing until very late in the game.

Bruno also said that he plans on flying Vulcan twice in ’22. We shall see.

Sunspot update: Sun continues to be more active than predicted

12:45 pm

Time for our monthly sunspot update, using NOAA’s most recent monthly graph of sunspot activity. That graph is below, annotated to show the previous solar cycle predictions and thus provide context. It covers all activity through the month of November.

The pattern for the past two years since the end of the solar minimum continues, with sunspot activity consistently exceeding the prediction of NOAA’s panel of solar scientists, as indicated by the red curve. The activity in November dropped very slightly from October, but remained more active than the prediction.

Today’s blacklisted American: Professor fired for mistakenly confusing the names of two black students

11:43 am

Fordham: A Jesuit University where racism rules
Fordham: A Jesuit University where racism rules.

The new dark age of silencing: An English professor at Fordham University in New York, Christopher Trogan, was fired shortly after he made the unforgivable sin of accidently mixing up the names of two black students.

The name mix-up occurred on Sept. 24 in a Composition II class taught by Trogan. The two students whose names were mixed up sent Trogan an email after class expressing that they felt disheartened and disrespected, and believed the mistake occurred because they were both Black.

Later that day, Trogan sent an email addressing the situation to all of his students in both sections of his Composition II course. He referred to the name mix-up as an “innocent mistake” and said he had a “confused brain” because the two students arrived late while he was reading the work of another student at the lecturer podium. “The offended student assumed my mistake was because I confused that student with another Black student,” Trogan said in his email to students. “I have done my best to validate and reassure the offended student that I made a simple, human, error. It has nothing to do with race.”

Weird storms on Jupiter

9:03 am

Storms on Jupiter
Click for full image.

Cool image time! The photo to the right, reduced to post here, was taken during Juno’s 38th close fly-by of Jupiter. It was enhanced and released yesterday by citizen scientist Kevin Gill to bring out the storm details, both of the large white storm at the bottom of the photo and the oblong eddy in the center.

Note the white puffy clouds sticking up from both larger cyclones. These tiny thunderheads are probably about the size of a very large Earth storm, but I am guessing. I don’t know the scale, but I suspect the Earth would fit within this image.

The oblong storm is actually an eddy that is swirling around the white and more stable storm below it.

More delays for SLS?

8:32 am

According to a report today at Ars Technica, there is an engine issue with the SLS rocket presently being prepared for a February unmanned test flight that could delay the launch for months.

The info is buried at the very bottom of the article:

There’s an issue with an SLS engine controller. This past weekend, rumors emerged about a problem with the controller for one of the four RS-25 engines that power the Space Launch System. NASA has not officially commented, but Aviation Week’s Irene Klotz spoke with Aerojet’s RS-25 program manager, Jeff Zotti. Troubleshooting the problem began on November 22, Aviation Week reported.

Schedule impacts yet to be determined … If necessary, “replacing a line or a component … we’re probably talking about multiple days. Replacing an engine, we’re probably talking about multiple weeks,” Zotti told the publication. “On top of that, we have to assess what that does and how that affects the vehicle and the integration activities that are going on,” he added. All of that must be factored into a potential delay of the launch, presently scheduled for February 12. A summer launch for the SLS now seems far more likely than spring.

Any delay beyond March poses a very serious and complex problem. The solid rocket strap-ons have a one year life expectancy once stacked, and both were initially stacked about a year ago. The February launch pushes that life span somewhat. A longer delay is more than can be waived.

SpaceX completes Starlink/BlackSky Falcon 9th launch

11:10 pm

Capitalism in space: SpaceX tonight successfully launched 48 Starlink satellites and 2 BlackSky commercial Earth observation satellites using its Falcon 9 rocket.

This was the 27th successful launch by SpaceX, extending its record this year for the most launches in a year by any private company ever. The first stage made its ninth successful flight, landing successfully on the drone ship in the Atlantic. The fairings were new, but were expected to be recovered and reused.

The leaders in the 2021 launch race:

45 China
27 SpaceX
20 Russia
5 Europe (Arianespace)

China’s lead of the U.S. in the national rankings is now 45 to 42.

Dropkick Murphys – The Season’s Upon Us

6:01 pm

An evening pause: As important as the Christmas season might be to family and friends, I think this song reminds us that friendship and family also must include humor and a requirement that we do not take ourselves too serious.

And boy, those two little kids must have had a blast making this video.

NASA awards contracts to three private space station projects

4:48 pm

Capitalism in space: NASA today announced development contract awards to three different private space station projects.

  • Nanoracks Starlab concept won $160 million. Partners include Voyager Space and Lockheed Martin.
  • Blue Origin’s Orbital Reef project was awarded $130 million, partnering with Sierra Space, Boeing, and Redwire.
  • Northrop Grumman won $125.6 million on a concept based on upgrades to its Cygnus freighter.

All three contracts are Space Act agreements, designed by NASA to jumpstart the companies and their design efforts. All three are in addition to the effort by Axiom to build its own ISS modules that will eventually detach to form its own independent station.

That’s four private American space stations now in the works. All are aiming to launch before this decade is out.

Today’s blacklisted American: Kyle Rittenhouse temporarily forced out of ASU

1:31 pm

How the left views someone found not guilty: GUILTY!
The contempt leftist students at ASU have for the law

It appears being found innocent of a crime no longer is sufficient for the jack-booted storm-troopers on the student left. Heavy protests at Arizona State University against Kyle Rittenhouse‘s attendance at the university as an online student has now apparently forced him out of ASU, at least temporarily.

From the first link:

Students groups like MEChA (Movimiento Estudiantil Chicanx de Aztlán), Students for Socialism, Students for Justice in Palestine and the Multicultural Solidarity Coalition are organizing a rally this week to “get murderer Kyle Rittenhouse off [the] campus.” He is not on campus since he is enrolled as an online student. (Indeed, some reports indicate that he may not be currently enrolled for any classes at ASU). However, Rittenhouse has expressed interest in in-person attendance at ASU. Students and faculty are being called to the rally to “protect students from a violent, blood-thirsty murderer.”

How tolerant of them. As far as these brownshirts are concerned, Rittenhouse will always be guilty, no matter what, and should fry in hell. Or at least, he should be sent to a concentration camp where these leftists believe all their opponents should be sent. Gas chambers next if possible.

When this anti-Rittenhouse demonstration did occur on December 1st, it suddenly found itself overwhelmed by conservatives chanting “Let’s Go Brandon!” and “Self-Defense!” The videos at this link are fun to watch, as the leftists keep advocating positions of hate and bigotry (“All whites are bigots”) while the protesters stand for self-defense, freedom, and fair play. And there do appear to be as many pro-Rittenhouse protesters as anti.

Many of the conservatives crashing the leftist protest were also apparently supporters of Kari Lake, who is a former Arizona television news anchor running for governor, with Donald Trump’s endorsement.

It appears that Rittenhouse might still attend ASU, even in person. From the last link:

“Amid his most recent semester, Kyle’s professors at Arizona State University recommended a compassionate withdrawal of his online classes. Now that the trial is behind him, Kyle is eager to enroll in more classes. He is hopeful that attending Arizona State in person will soon be an option,” Hancock [Rittenhouse spokesman] said.

If he should do so, Rittenhouse should be prepared for violence against him. Arizona however is an open-carry state. He will be within his rights to walk around openly armed. I also suspect that many of the conservatives who crashed the leftist protests will be eager to stand by him in support, equally armed.
