Doctor Who – The Master Summons the Sea Devil
An evening pause: I never watched Dr. Who, so I have no idea if this clip is a typical representation of the show. Its schlockiness however is quite impressive.

Today’s blacklisted American: Long Beach to discriminate against any employee who refuses COVID jab
If they could, the Democrats would do this to anyone who opposes them.
Blacklists are back and the Democrats have got ’em: The local government of Long Beach, California will on June 6, 2022 begin harsh discrimination and punishment against any city employee who refuses to get the COVID jab.
Anyone granted the personal exemption option must pay for weekly COVID-19 testing (rapid antigen/PCR), which can be done during city work hours, with the cost of the testing deducted from the employee’s paycheck, according to Ambrosini’s memo. Those receiving medical or religious exemptions will still be subject to weekly COVID-19 testing, but at city expense, according to the memo.
All unvaccinated city employees must continue to wear a mask of at least medical or surgical grade while at work under this new policy, according to memo. Employees not doing so are subject to disciplinary measures, up to and including termination, according to the policy.
Employees found not in compliance with the vaccination mandate will be subject to a wide range of disciplinary measures, including up to six months of suspension and then possible separation or even termination should non-compliance continue, according to the city.
The absurdity and injustice of this is even more pronounced considering the vast evidence now available to show the COVID shots don’t provide any real protection while carrying a potential health risk to those that take it.

Curiosity on a steep slope
Click for full panorama.
Click for interactive map.
Cool image time! The panorama above, cropped, reduced, and enhanced to post here, was compiled from 29 photos taken on May 31, 2022 by the right navigation camera on the Mars rover Curiosity. It shows the steepness of the slope that the rover ended up parking on yesterday after it completed its drive. As noted in today’s rover update by Abigail Fraeman, Planetary Geologist at NASA’s Jet Propulsion Laboratory:
Curiosity starts the plan parked at an impressive 17˚ pitch (front up) and 17˚ roll (left up) for a total 24˚ tilt. You can get a bit of a sense of the rover’s non-horizontal position by looking at its orientation with respect to the ground in the above Navcam mosaic. Even though this slope is getting close to the limit of what Curiosity can traverse, we don’t think we’ll have any problems unstowing the arm or driving the rest of the way to the top because of the terrain we’re on – nice smooth bedrock with only a thin sand cover is almost the Martian equivalent of a paved road.
On the far right of the image you can also see Curiosity’s tracks. The rover had first approached this slope about 80 feet to the west, then backed off slightly to parallel the slope as it came east and then turned uphill. In the far far distance can be seen the rim of Gale Crater, about about 30 miles away and obscured by the atmosphere’s winter dust.
The overview map above shows Curiosity’s location with the blue dot. The approximate area covered by the section of the panorama above is indicated by the yellow lines. The red dotted line shows the rover’s original planned route. The white arrows indicate what the scientists have dubbed the “marker horizon,” a distinct layer found in many places on the flanks of Mount Sharp that they are very eager to study up close. The green dot marks the approximate location of a recurring slope lineae, a place where the cliff is seasonally darkened by a streak that appears each spring and then fades.

Astronomers used Japanese weather satellite to monitor the dimming of Betelgeuse

In a paper published on May 30th, astronomers described how they used the Japanese weather satellite Himawari-8 to monitor the dimming of Betelgeuse that occurred in 2019 and 2020.
“We saw a tweet stating that the moon was in its images,” Daisuke Taniguchi, a Ph.D. student in astronomy at the University of Tokyo and first author of the paper, told Space.com. “I chatted with [third author] Shinsuke Uno on the usage of meteorological satellites for astronomy, found Betelgeuse is in the field of view of Himawari-8 and realized that maybe the Great Dimming of Betelgeuse could be investigated.”
Himawari-8 has been positioned 22,236 miles (35,786 kilometers) above Earth’s equator since 2015 to study weather and natural disasters (including the eruption of the Hunga Tonga-Hunga Haʻapai volcano on Jan. 15). Although the satellite is up there to image Earth every 10 minutes, the edges of its images include stars.
Taniguchi and his colleagues were able to see Betelgeuse in images taken throughout Himawari-8’s lifetime and measured its brightness roughly every 1.7 days between January 2017 and June 2021.
The scientists were lucky that the star’s unexpected dimming happened to occur during this time period. The image above is Figure 1 from their paper (which you can read here).
They note that their observations appeared to confirm the theory that the dimming was caused by a dust cloud crossing in front of the star, not the theory that it was caused by a dark spot on the star’s surface. Moreover, their data suggests that dust was relatively close to the star, and could even been created by a burst from the star.

Blue Origin reschedules next New Shepard flight
Capitalism in space: Blue Origin announced yesterday that it has rescheduled the next New Shepard passenger flight for June 4.
The original launch date of May 20th had been scrubbed because of an unexplained issue with the spacecraft’s “back-up systems.” The company has not provided any further information on what had been wrong, or what had been done to fix it.
This flight will be New Shepard’s fifth passenger flight, and its 21st overall.

Webb to release first science images July 12th
The science team for the James Webb Space Telescope announced today that the first infrared science images from the telescope will be released on July 12, 2022.
The first images package of materials will highlight the science themes that inspired the mission and will be the focus of its work: the early universe, the evolution of galaxies through time, the lifecycle of stars, and other worlds. All of Webb’s commissioning data – the data taken while aligning the telescope and preparing the instruments – will also be made publicly available.
In many ways this first release will likely mirror the first release of images from the Hubble Space Telescope in 1993, after its serious focus problem had been solved. Then, the science team and NASA picked images for the press conference that, to them, would pass what they called the “grandmother test,” whereby an ordinary person not familiar with space objects would still instantly recognize the object imaged.
The result of that criteria was that some of Hubble’s best ground-breaking first images were not included, such as its first sharp picture of the exploding star Eta Carinae. While the images shown were beautiful, they did not immediately demonstrate what Hubble was going to accomplish. The Eta Carinae picture did however.
Hopefully this time the scientists will be more daring, and have a greater respect for the general public, and include some infrared images that are not familiar to non-scientists. It is such data that is almost always the most exciting.
