Today’s blacklisted American: Leftist academic suspended by college for expressing her opinions
Under modern leftist academic thought, soon everyone
will be witch who must be burnt.
Eating their own: Santa Barbara City College (SBCC) in California has suspended the vice president of its extended learning program, Joyce Coleman, because she made comments about the World War II Japanese internment camps that apparently offended some Asians.
Apparently Coleman, who only started her job at SBCC six months ago, made her comments during a March Equal Opportunity Advisory Committee meeting in connection with the formation of “a new campus affinity group on behalf of Asian-American Pacific Islanders.”
The complaint alleges Coleman, who is Black, reportedly greeted news of the new group’s formation with the words, “About time,” and then described having visited an internment camp for Japanese and Japanese American people during World War II and wondering why the prisoners there “did not just leave,” given how small the fence was. By contrast, Coleman allegedly noted, Black American slaves formed the Underground Railroad and actively resisted.
Some campus faculty and staff took offense to what they described as “victim blaming,” charging that she inflicted “great harm” by her words and actions.
My heart be still. Her words offended someone. What a tragedy! She obviously must be fired immediately and forbidden to work anywhere in America ever again. The suspension is certainly insufficient!
The irony here is that Coleman is herself a proud modern leftist who thinks all whites are bigots and must be punished. For example, during a presentation she gave at a college book club, she had the group watch…

Zhurong finally located on Mars
Click for full image.
Though the Chinese had earlier this week released one image taken by their Mars orbiter, Tianwen-1, showing their rover Zhurong on the surface of Mars, they did not provide any specific location information.
This lack has now been filled by a new high resolution image of Zhurong taken by Mars Reconnaissance Orbiter (MRO) on June 6, 2021. This image, cropped to match the Tianwen-1 image and annotated by me to post here, shows the parachute, entry capsule, heat shield, lander, and rover. I have added white dots to distinguish the rover from the lander, which indicate that since the Tianwen-1 orbital image the rover had moved south about 70 feet, suggesting it has been able to travel on the surface.
What this MRO image provides that the Chinese refused to reveal is the latitude and longitude of that landing site, which in turn tells us that the lander put down about 14 miles to the northwest of its targeted landing spot. The mosaic of MRO context camera images below show this landing spot in context with the surrounding terrain.

Update on Perseverance’s future travel plans
Click for full image.
The science team for the rover Perseverance yesterday released a revised map of where they intend over the next few months to send the rover on the floor of Jezero Crater.
The map to the right, cropped and reduced to post here, shows that route.
The first science campaign (depicted with yellow hash marks) begins with the rover performing an arching drive southward from its landing site to Séítah-North (Séítah-N). At that point the rover will travel west a short distance to an overlook where it can view much of the Séítah unit. The “Séítah-N Overlook” could also become an area of scientific interest – with Perseverance performing a “toe dip” into the unit to collect remote-sensing measurements of geologic targets.
Once its time at the Séítah-N Overlook is complete, Perseverance will head east, then south toward a spot where the science team can study the Crater Floor Fractured Rough in greater detail. The first core sample collected by the mission will also take place at this location. After Cratered Floor Fractured Rough, the Perseverance rover team will evaluate whether additional exploration (depicted with light-yellow hash marks) farther south – and then west – is warranted.
Whether Perseverance travels beyond the Cratered Floor Fractured Rough during this first science campaign, the rover will eventually retrace its steps. As Perseverance passes the Octavia B. Butler landing site, the first science campaign will conclude. At that point, several months of travel lay ahead as Perseverance makes its way to “Three Forks,” where the second science campaign will begin.
At that point the rover will begin studying the base of the delta of material that in the far past poured through a gap in the western rim of Jezero Crater.
“The Endless SLS Test Firings Act”
The Senate passes a law! In the NASA authorization that was just approved by the Senate and awaits House action was an amendment — inserted by Senator Roger Wicker (R-Mississippi) — that will essentially require NASA to build an SLS core stage designed for only one purpose, endless testing at the Stennis Space Center in Mississippi.
The Stennis-specific provision says NASA should “initiate development of a main propulsion test article for the integrated core stage propulsion elements of the Space Launch System, consistent with cost and schedule constraints, particularly for long-lead propulsion hardware needed for flight.”
So what exactly is a “main propulsion test article,” and why does NASA need one? According to a Senate staffer, who spoke to Ars on background, this would essentially be an SLS core stage built not to fly but to undergo numerous tests at Stennis.
My headline above is essentially stolen from the Eric Berger article at the link. Because this ground test core is not funded, at best it would likely not be ready for testing prior to ’27 or ’28, at the earliest. By then who knows if SLS will even exist any longer, replaced by low-cost and far more useful commercial rockets. Thus, if this Wicker amendment survives, Stennis might be testing a core stage endlessly for a rocket that no longer exists.
And even if SLS is flying, what point is there to test a core stage that never flies? None, except if you wish to create fake jobs in Mississippi for your constituents, as Wicker obviously is trying to do.
Fortunately the bill is merely an authorization, and has not yet passed the House. Much could change before passage, and even after passage money will need to be appropriated to create this fake testing project.
Unfortunately, we are discussing our modern Congress, which has no brains, can’t count, and thinks money grows on trees. I would not bet against this fake testing program becoming law.
Europe to fly mission to Venus to study its volcanoes
The European Space Agency yesterday announced that it will fly an orbiter to Venus in 2031, dubbed EnVision, to study the estimated million volcanoes on the surface of that hellish planet.
EnVision will use an infrared spectrometer to seek out hot spots on the surface that could indicate active volcanoes. It will use radar to map the surface, looking for signs of lava flows. Ultraviolet and high-resolution infrared spectrometers will then look for water vapor and sulfur dioxide emissions, to see whether smoldering volcanoes are driving cloud chemistry today.
This data will help determine exactly geologically active Venus’s volcanoes are. Several studies in the past decade using archival data (see here, here, and here) have suggested as many as 37 of those volcanoes are active, but this data remains uncertain.
China’s Long March 2D rocket launches 4 satellites
Using its Long March 2D rocket China today placed four satellites into orbit, two to observe the Earth, one to study asteroids, and one a technology test satellite.
No word on where the rocket’s first stage booster landed within China.
The leaders in the 2021 launch race:
18 SpaceX
16 China
8 Russia
2 Rocket Lab
2 ULA
The US still leads China 24 to 16 in the national rankings.
Training WWII gunners to hit moving planes from a moving plane
An evening pause: While figuring out why this works is really complicated, the simplicity of the technique and engineering is superb, and illustrates again why the U.S. did so well against Germany.
And yes, that is the voice of Mel Blanc.

Evidence of past underground water in the Martian equatorial regions?
Click here, here, here, and here for full images.
Today’s cool image, to the right, takes us to the equatorial regions of Mars, a region that today appears quite arid and dry based on all the orbital and rover/lander data so far gathered. The photo and its complex geology however provides us a hint that once liquid water did exist here. At least, that is the hypothesis that scientists presently favor, though making it fit this complex geology is not simple or straightforward.
The mosaic to the right is made from four context camera images taken by Mars Reconnaissance Orbiter (MRO). It shows a very complicated series of depressions — one of which vaguely resembles a crater — that appear to have been washed out by some past erosion process, though that process could not have been that simple because of the fissures and cracks that dominate the floor of the circular feature.
I contacted Chris Okubo of the U.S. Geological Survey, who had requested a high resolution image from MRO of a small part of this mosaic, as indicated by the white box, to ask him what we are looking at. His answer was appropriately noncommittal:

Today’s blacklisted American: College endorses segregation against whites, turning former coffee shop into blacks-only haven
The Civil Rights Act of 1964: unilaterally repealed by Beliot College.
The new bigotry on American campuses: Beliot College in Wisconsin has decided to turn a former campus coffee shop into blacks-only haven, thus re-introducing Jim Crow segregation by treating blacks as a privileged race and all other ethnic groups and races as inferior and thus deserving of discrimination and second-class facilities.
In March, the private institution announced the Java Joint would be closed in order to become “a haven for Beloit College’s Black students.”
The gathering space was praised by Jada Daniel, the current Black Student Union president. “We hope to create a safe space for Black and Brown students, where we have a comfortable place to study,” said Daniel on the school’s website. “Daniel said BSU plans to host Soul Food Sundays, poetry readings, and other events during the year, following COVID safety guidelines,” the website says.
Meanwhile, when questions were raised about this clearly discriminatory policy, the school refused to comment, even as its own website said this:

Sierra Space makes deal with UK spaceport for Dream Chaser landings
Capitalism in space: Sierra Space has signed an agreement with a spaceport in Cornwall, England, allowing it to land its Dream Chaser mini-shuttles there.
Sierra Space signed a memorandum of understanding (MOU) with Spaceport Cornwall expressing support for future landings of Dream Chaser at the spaceport, also known as Cornwall Newquay Airport in southwestern England.
The MOU came after Sierra Space performed a study, supported by the U.K. Space Agency, evaluating the feasibility of using the spaceport for Dream Chaser landings. The lifting body vehicle is designed to glide to a landing on runways, and the initial study concluded the spaceport is “a suitable and viable return location for the orbital return” for Dream Chaser, Sierra Space said in a statement.
The more places Sierra can land Dream Chaser the more commercially viable it will be. For Cornwall, this strengthens its position as a spaceport, having already signed an agreement with Virgin Orbit to allow it to launch from there.
