Thick flow into Mamers Valles on Mars

Cool image time! The photo to the right, cropped and reduced to post here, was taken on July 24, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “viscous flow” that has apparently carved the wide curving canyon as it slowly flows into open country to the south.

I would estimate the height of that canyon wall to be around 3,000 feet, though this is a very rough guess. I also image a trail switchbacking up the nose of that canyon wall would make for a truly stupendous hiking experience.

The flow filling the canyon floor appears very glacial, which is not surprising as this canyon is at 37 degrees north latitude, in the mid-latitude band where many glacial features are found. The overview map below provides some more detailed context.

China’s Long March 11 launches from floating sea platform

11:26 am

China today successfully launched two “navigation satellites” from a floating sea platform in the Yellow Sea, using its Long March 11 rocket.

The platform was only about two miles off shore at launch, so the view from the beach drew a large crowd. Video at the first link.

The leaders in the 2022 launch race:

45 SpaceX
42 China
12 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 65 to 42 in the national rankings, and the entire globe combined 65 to 62. These numbers will change again later today, with a SpaceX commercial launch scheduled for 4:06 pm (Pacific).

Today’s blacklisted American: Black playwright blackballed because he honestly told the story of racism in the Jim Crow south

Carlyle Brown, censored for writing truthfully
Carlyle Brown, censored for writing truthfully

The modern dark age: Close-minded students at the black student association at Texas Wesleyan University have forced the cancellation of a play celebrating the civil rights movement in Mississippi in the 1960s — written by black author Carlyle Brown — because it included realistic dialogue of the time, including the word “nigger”.

Students objected to the use of the n-word in a play that tries to capture the environment of hate and racism of the period. Texas Wesleyan’s Black Student Association declared the reference to be harmful and “triggering.” Calling for a boycott, the Association declared that allowing the play to be heard would “further hurt Black students and possibly students from other marginalized communities.”

The Rambler student newspaper reported that school and theater officials killed the production after a 90-minute campus discussion: “The main concern the students voiced was the ‘triggering’ effect of using the racially explicit word, which is repeated 11 separate times throughout the play, and how it can cause trauma to the black students in the audience.”

The play, Down in Mississippi, can be read here [pdf]. From the play’s summary:

Rocket Lab successfully launches NOAA satellite

10:34 am

Capitalism in space: Rocket Lab today successfully used its Electron rocket to place a NOAA satellite into orbit, designed to gather data from ground-based sensors.

This was the company’s eighth successful launch in 2022, the most it has achieved in any single year. No attempt was made to recover the first stage on this launch.

The leaders in the 2022 launch race:

45 SpaceX
41 China
12 Russia
8 Rocket Lab
7 ULA

American private enterprise now leads China 65 to 41 in the national rankings, and the entire globe combined 65 to 61. The 65 successful launches so far this year is now the second most successful American year in rocketry, exceeded only by the 70 launches in 1966. With almost three months left to go in the year, 2022 looks like it will top that record, by a lot.

SpaceX meanwhile has a launch scheduled for later today, after getting scrubbed yesterday at T-30 seconds because of detected minor helium leak.

Endurance docks at ISS

9:16 am

Like clockwork SpaceX’s Endurance capsule successfully docked at ISS yesterday, delivering four astronauts to the station for a six month mission.

The most interesting aspect of this launch and crew is Russian Anna Kikina.

Kikina is the first Russian to fly aboard a U.S. spacecraft in nearly 20 years. She and Rubio were launched under a new agreement between NASA and Roscosmos, the Russian space agency, that ensures at least one astronaut or cosmonaut is always aboard the space station even if a Crew Dragon or Soyuz is forced to depart early, taking its crew with it.

Without the seat-swap arrangement, a medical emergency or some other major problem could leave an all-Russian or all-NASA crew aboard without the expertise to operate the other nation’s systems.

The agreement had been stalled almost entirely by the former head of Roscosmos, Dmitry Rogozin. He is now gone however, sent by Putin to take over the fake occupation government in parts of the Ukraine. It appears his bellicose manner, that caused the loss of a billion dollars in launch contracts with OneWeb, was more than even Putin could handle.

With him gone, the new head of Roscosmos, Yuri Borisov, quickly finalized this astronaut barter deal. He has also publicly acted to try to ease tensions between the U.S. and Russian space agencies.

Startup smallsat rocket company signs spaceport deal with Brazil

9:02 am

The new colonial movement: A Canadian startup smallsat rocket company, C6 Launch Systems, has not only signed a spaceport deal with Brazil to build its own launchpad at that country’s Alcantara Space Center, it has also won its first launch customer.

First, the launchpad is for C6’s rocket, which is unnamed and designed to launch cubesats. The company webpage says they are aiming for suborbital flights in 2021 and orbital flights in 2022, but it is unclear if it has launched anything at this point.

Nonetheless, Brazil is very clearly teaming up with C6. The Brazilian air force hired it to build a launch pad, a Brazilian company, Concert Technologies, has awarded it a launch contract.

Concert Technologies S.A. who are developing a new small satellite constellation have signed a a non-exclusive letter of intent to launch three small satellites with C6 Launch. The broad agreement allows for Concert Technologies to schedule more launches to maintain and expand their high-resolution Earth Observation (EO) constellation.

It appears Concert’s satellites will be targeting both the Earth imagery market as well as communications services in the “internet of things.”

Martian crater and mesa sculpted by ancient flow

1:14 pm

Martian crater and mesa sculpted by ancient flow
Click for full image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on June 15, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a crater whose ejecta has been sculpted to the east into a teardrop-shaped mesa by some ancient flow, coming from the west.

The crater itself is located in one of several outflow canyons draining out from the volcanic Tharsis Bulge into the northern lowland plain of Chryse Planitia, the biggest of which is Valles Marineris. This particular canyon is one of the smaller and is dubbed Ravi Vallis.

The overview map below illustrates why many scientists think the flow that shaped this mesa came from a catastrophic flood of liquid water, billions of years ago.

Important Roscosmos official endorses continuing cooperation with US in space

12:28 pm

In a clear sign of the distinct change in atmosphere since the removal of Dmitry Rogozin as head of Roscosmos, the executive director of human space flight programs at Roscosmos, Sergei Krikalev, yesterday endorsed the longstanding cooperation between the U.S. and Russia in space.

Krikalev’s comments came after the launch yesterday of Endurance with one Russian astronaut as part of its four-person crew.

At a briefing after the Oct. 5 launch of the Crew-5 mission from the Kennedy Space Center, Sergei Krikalev, executive director of human space flight programs at Roscosmos, emphasized long-running cooperation between the United States and Russia in civil space, cooperation that has been strained since Russia’s invasion of Ukraine in February.

“We just continue what we started many years ago in 1975 when the Apollo-Soyuz crew worked together, and now we continue our cooperation,” he said after mentioning a “new phase of cooperation” with the exchange of seats between NASA and Roscosmos.

To understand the importance of Krikalev’s comments, you must also understand the context. First, Krikalev is a very significant figure in the history of Russia. He was called the last Soviet citizen, having been stranded on Mir an extra few months when the Soviet Union fell in 1991. Then he was the first Russian to fly on the shuttle, followed later by being on the first mission to ISS, when it was only two modules.

Since his retirement as an active astronaut, he has become the man in charge of Russia’s manned program, where he clashed with Rogozin several times over policy. His opposition to Rogozin almost certainly was a factor in Rogozin’s removal.

Krikalev’s endorsement of continuing the U.S-Russian partnership only cements that partnership, especially because Krikalev himself is a dyed-in-the-wool communist at heart. At least, he said so emphatically when I interviewed him at length in 2003 for Leaving Earth. I doubt his mind has changed in this matter, though his relentless honesty as an engineer has probably shaken his dedication to that failed ideology in subsequent years.

Nonetheless, his standing in Russia gives any statement he makes great weight. Expect more efforts by the Russians to ease tensions with the U.S., though their chances of success will be limited as long as Russia is continuing its unprovoked invasion of the Ukraine.

Pushback: Because of Yale Law School’s enthusiasm for blacklisting, more than a dozen judges now refuse to hire its graduates

11:46 am

Yale Law School's instruction guide
Yale Law School’s instruction guide

Bring a gun to a knife fight: Following the public announcement by Judge James Ho of the U.S. Court of Appeals for the Fifth Circuit that he would no longer hire Yale graduates as law clerks because of that school’s enthusiasm for blacklisting and censorship, it appears that a dozen other judges have joined his boycott as well.

“Students should be mindful that they will face diminished opportunities if they go to Yale,” said a prominent circuit court judge, whose clerks have gone on to nab Supreme Court clerkships. “I have no confidence that they’re being taught anything.”

With one exception, the judges made clear this is a policy they are imposing on future—not current—Yale Law School students.

Ho’s public speech was even more harsh.

“Yale presents itself as the best, most elite institution of legal education. Yet it’s the worst when it comes to legal cancellation.” The school “sets the tone for other law schools, and for the legal profession at large. I certainly reserve the right to add other schools in the future. But my sincere hope is that I won’t have to. My sincere hope is that, if nothing else, my colleagues and I will at least send the message that other schools should not follow in Yale’s footsteps.”

Ho’s message to law schools was clear: “If they want the closed and intolerant environment that Yale embraces today, that’s their call. But I want nothing to do with it.”

Nor is Ho exaggerating about Yale’s intolerant track record. » Read more

Engineers still struggling to regain full control of CAPSTONE

10:50 am

Though its batteries are now getting charged by the Sun, engineers have still not regained full control of the smallsat lunar orbiter CAPSTONE, presently on its path towards the Moon.

As per the latest update:

The CAPSTONE mission team is continuing to work towards recovery of the spacecraft full three-axis control. This work includes collecting information from the spacecraft, running simulations, and refining recovery plans. The vehicle remains stable and power positive in its current configuration.

In other words, they’ve got the spacecraft oriented so that its solar panels can gather enough sunlight to charge the batteries, but its attitude remains incorrect and they do not yet have CAPSTONE fully under their control.

The spacecraft arrives in lunar orbit on November 13, 2022. At that time however it will have to do an engine burn to enter lunar orbit, and if full control is not regained by then this burn will not be possible because engineers will not be able to point it correctly.
