How to Replace Blinker Fluid
An evening pause: I posted this important advice for maintaining one’s car back in 2017. I think it is important enough that it needs to be reposted. Make sure you watch to the very end.
SLS dress rehearsal begins, with press coverage limited by NASA
NASA today began the two-day-long “wet dress rehearsal” countdown of its first SLS rocket, with T-0 expected to occur at 2:40 pm (Eastern) on April 3rd.
The article at the link provides all the information you could want about this rocket, which is now about seven years behind schedule and having a cost so far about $25 billion. This quote however tells us much about the mentality at NASA:
But much of the test will happen without independent press coverage. NASA plans to provide sanctioned updates on the two-day dress rehearsal via the agency’s website and social media accounts, but news media representatives are not being permitted to listen to the countdown activities.
NASA has cited security and export control restrictions for the move. Numerous media representatives requested access to the SLS countdown audio for the wet dress rehearsal. Launch countdown audio feeds for other U.S. rockets, including those developed by private companies and hauling sensitive U.S. military satellites into orbit, are widely available to the news media and the public.
…NASA plans to release only text updates through the weekend. NASA TV will not be airing any live commentary for the final hours of the practice countdown. The agency’s television channel has previously provided live coverage of similar events, such as space shuttle tanking tests. [emphasis mine]
NASA reasons for not allowing anyone to listen to its audio feed — “security and export control restrictions” — is an utter lie. The real reason is that NASA fears the public’s reaction should anything not go exactly as planned. By blocking access to the audio feed, they can hide any faux pas.
NASA’s fear of course is misplaced. This is a test. No one will be surprised or outraged if it doesn’t go perfectly. Better to be open and up front than try to hide problems, because eventually those problems will be revealed and the cover-up will do far more harm to NASA’s reputation than the problems themselves.
The many new private rocket companies, SpaceX, Rocket Lab, Astra, Virgin Orbit, understand this, which is why they all make their primary countdown audio feeds available, though of course they almost certainly have secondary private feeds where engineers can speak more freely. Similarly, NASA did the same in the 1960s, and then during the entire shuttle program.
Now however “export control restrictions” and “security” requires them to be secretive? It is to laugh.
Sunspot update: Sunspot activity continues to outpace predictions
It is the first of the month, and NOAA has once again updated its monthly graph showing the long term trends in the Sun’s sunspot activity. As I do every month, I post it below, annotated with additional data to provide some context.
In March the Sun continued its unexpected high activity since the end of the solar minimum in 2020. The number of sunspots once again rose steeply, while also exceeding the predicted count for the month. The actual sunspot count for March was 78.5, not 34.1 as predicted. The last time the count was that high for any month was September 2015, when the Sun was just beginning its ramp down from solar maximum.

Strange terrain at the Martian equator
Click for full image.
Cool image time! The photo to the right, cropped to post here, was taken on January 29, 2022 by the high resolution camera of Mars Reconnaissance Orbiter (MRO). It shows a small portion of the floor of 41-mile-wide Tuskegee Crater, sitting at the Martian equator on the rim of the outlet to the giant canyon Valles Marineris.
I have purposely focused on a section of the color strip, because of its strange green color. Most MRO images are reddish (indicating dust) or blue (indicating coarse rocks or ice). Green seems to me to be rare, and in fact is not even mentioned in the MRO science’s team explanation [pdf] of the colors the instrument produces. Since green is neither dust nor ice, this suggests some form of hard bedrock, with a mineralogy that produces that color.
The overview map below gives some context.

Today’s blacklisted American: Biden’s Labor Board attempts to silence conservative news outlet for making bad Twitter joke
Ben Domenech and The Federalist, censored by the federal government’s
National Labor Relations Board
Blacklists are back and the Democrats have got ’em: The National Labor Relations Board (NLRB) is attempting to silence the conservative news site The Federalist for “unfair labor practice” because its publisher Ben Domenech sent out a bad Twitter joke in 2019 about unions, and two lawyers who had nothing to do with the company complained to the NLRB.
The National Labor Relations Board (NLRB) has ordered Ben Domenech—publisher of the conservative website The Federalist…—to take down a June 2019 tweet in which he joked about sending employees who wanted to unionize to work in “the salt mines.” Domenech has refused, and the case is now making its way through the courts.
Domenech’s tweet came in response to news that employees of Vox Media Inc. walked off the job in support of unionization. No one at The Federalist had publicly expressed any interest in unionizing, and two of the website’s six employees filed affidavits attesting that they viewed the tweet as a joke. As far as I know, Domenech doesn’t own any salt mines.
The complainants, leftist lawyers Matt Bruenig (a former NLRB attorney) and Joel Fleming, have never worked for or been personally harmed by the Federalist and were clearly acting to silence their political opponents by taking advantage of NLRB’s overly broad regulations, which allow total strangers to file complaints against businesses they don’t like. The NLRB then moves to harass those businesses.

SpaceX successfully launches 40 smallsats into orbit
Capitalism in space: SpaceX today successfully used its Falcon 9 rocket to launch 40 smallsats into orbit.
The first stage successfully landed on a drone ship, completing its seventh flight.
The leaders in the 2022 launch race:
12 SpaceX
8 China
4 Russia
2 ULA
The U.S. now leads China 18 to 8 in the national rankings.
Will XCOR’s Lynx’s spaceplane be reborn as smallsat launcher taking off from California airport?
Capitalism in space: Wagner Star Industries, a startup that now owns the unfinished Lynx spaceplane that bankrupt XCOR had intended for suborbital tourists flights, has signed a agreement with Paso Robles Municipal Airport in California to launch from there.
Wagner’s plan is to reconfigure Lynx as an unmanned first stage that would launch smallsats into orbit. It would launch and land on a runway from Paso Robles.
Wagner Star is in the process of converting the first Lynx vehicle into a drone so it can begin tests, according to the company’s website. The work involves removing life-support systems that had been installed to support the pilot and passenger and installing equipment for remote controlled operation.
Quetzalcóatl would take off from a runway, release its payload in suborbital space, and then glide back to where it took off. The company said it would be able to launch satellites from any commercial airport runway for $5 million per flight. A suborbital flight without a satellite launch would cost $3 million.
A clever plan. I have doubts about the satellite launches, but using this plane to place drones into high altitude where they could then continue to fly for great distances will almost certainly appeal to the military.
Ronnie O’Sullivan’s record break in Snooker
An evening pause: Hat tip Phill Oltmann, who has tried several times to explain Snooker to me and failed. The game however appears to be a variation of the U.S. pool game hi-low, though maybe more complicated.
The point is that in the video below, O’Sullivan starts the game and proceeds to clear the table, and he does it in less than six minutes, the fastest time ever. It is amazing to watch.
The Ukraine War: Increasing Ukrainian gains in the past week

Another week has passed in the Ukraine war, and with it we begin to see increasing evidence that not only has the Russian invasion stalled, but that the Ukraine is beginning to push back with more and more effectiveness.
The two maps to the right are from the Institute for the Study of War (ISW) and have been simplified, annotated, and reduced to post here. The top was from ISW’s March 24, 2022 report, the bottom from its report today. The dark red areas are regions either controlled by Russia or areas of confirmed Russian advance. The light red indicates areas the Russians claim to control without confirmation. The blue areas mark areas retaken by the Ukraine in battle. The circles indicate areas of recent heavy fighting.
The green arrows I have added to both maps indicate areas where there have been changes since the week prior. Like last week, the arrows point almost entirely to areas where Russian control has ebbed, either because the Russians have chosen to retreat, or because Ukrainian forces have pushed them out. The summary from ISW is succinct:

Pushback: University’s blacklisting of a student quickly ends when confronted by lawyers
Boris Badenov: The school administrators at
Southern Illinois University
Today’s blacklist story came and went so quickly that no one in the press really ever had a chance to cover it. I however want to highlight it today because it tells us a great deal about today’s bankrupt academic culture, and its paper tiger nature if challenged.
On February 10, 2022, Jamie Ball, the director for Equal Opportunity, Access and Title IX Coordination at Southern Illinois University in Edwardsville, sent notices to Maggie DeJong, a student in the school’s Art Therapy Counseling Program, telling DeJong that she was forthwith forbidden to interact in any way with three other students.
Because DeJong attended classes and also worked at the same facility as these three students, the orders essentially blacklisted her from school through the end of the ’22 semester.
Ball provided no facts or reasons for the “no-contact” orders, other than saying that any contact between DeJong and these three students “would not be welcome or appropriate at this time.” Ball’s order also admitted that no harassment or violation of school policy had occurred. Her order was simply “to prevent interactions that could be perceived by either party as unwelcome, retaliatory, intimidating, or harassing.”
In other words, Ball was punishing DeJong for something that might happen, likely based on secret accusations made by those three students.
On February 23rd, less than two weeks later, lawyers from the Alliance Defending Freedom (ADF) sent the school’s Chancellor, Randy Penbrook, a letter [pdf] outlining the illegality of this action, and demanding the no-contact orders be immediately rescinded.
