Today’s blacklisted American: Georgetown University to hold segregated black-only events

5:02 pm

Blacks only event
Segregation returns to Georgetown University

“Segregation today, segregation tomorrow, segregation forever!” The Campus Ministry of Georgetown University has scheduled several upcoming events that are advertised as segregated and for blacks only, despite a claim on its website that such events “are accessible to students of all backgrounds.”

The announcement for one such event, which included the graphic to the right (with the relevant language circled in red), however proves that last claim is an outright lie:

The Cookout is an undergraduate retreat created for Black students by Black students to promote joy, inspire hope, and explore practices of self-love and care for Black students, drawing on the values and practices of Georgetown’s Ignatian heritage and other spiritual traditions. Sponsored by Campus Ministry, The Cookout acknowledges the marginalization Black students face in predominantly white institutions and aims to center Black experience, affirm the Blackness of all Black students, and facilitate a safe space for connection and reflection through bonding activities and talks by Black chaplains, faculty and staff. A cookout is a place for relaxation, laughter, and community—and we’re going to offer just that and more. So, to the Black students of Georgetown University: Welcome to The Cookout. [emphasis mine]

Of course, when questioned a university spokesperson said that while the event is meant for black students on campus, “all students are allowed to register.” It would really be interesting to see what would happen if some white students at Georgetown did exactly that, and then showed up. Would they be greeted with the university’s commitment to…

Cool image time! The panorama above, created by me from four photos taken by Curiosity’s right navigation camera on April 5, 2022, reveal much about the alien world of Mars that the rover is exploring. The red dotted line indicates approximately the rover’s upcoming route.

First there is the rough surface of the Greenheugh Pediment, the sloping plateau that Curiosity is presently traversing. Called “gater-back terrain” by the science team, this broken surface apparently is sandstone that was originally a dune field that in the past was periodically washed by water runoff and later hardened into this structurally weak rock.

Second, I have orientated the images so that the rim of Gale Crater, approximately 25 miles away, is horizontal. By doing so, we can see the upward slope of the Greenheugh Pediment. Curiosity is on a tilted surface, and while it will be traversing along a contour line as it heads west towards Gediz Vallis Ridge about 1,000 feet away, when it turns left and heads uphill, the climb will be steady and steep, as it has now been for the past year since the rover entered the mountains at the foot of Mount Sharp.

Taken together, these details indicate why Curiosity has moved very slowly in recent weeks, as shown by the white dots in the overview map to the right. The blue dot marks Curiosity’s present location, with the yellow lines indicate the approximate view in the panorama above.

Traversing the pediment carries real risk to the rover. Though its somewhat dinged wheels have held up well during this last year of traveling in these rough mountains, at any point the severe roughness here could damage one or more wheels significantly, even putting one or more out of commission. The rover team is traveling carefully to avoid this, but these factors illustrate a possible end for the rover, though hopefully still years away.

Inspector General: NASA’s lunar rover VIPER mission on schedule, with some cost increases

11:19 am

VIPER's planned route on the Moon

According to a report [pdf] issued today by NASA’s inspector general, the agency’s VIPER lunar rover mission is generally on schedule for its ’23 launch, though it has experienced some cost increases and still carries some scheduling risks, mostly related to the development of Astrobotic’s commercial Griffin lunar lander, and its precursor Peregrine mission that ULA hopes to launch on its first Vulcan rocket test.

Although Astrobotic personnel explained that Griffin’s development schedule is largely independent of its Peregrine mission, the Peregrine Lander—planned to launch in 2022—has multiple systems and subsystems that will also be used on Griffin. Therefore, any technical problems with these systems may adversely affect development of the Griffin Lander because Astrobotic would only have about a year, depending on the Peregrine launch date and start of lunar operations, to resolve the issues prior to NASA delivering VIPER for integration and launch. Furthermore, any failures during the Peregrine mission may lead to Griffin delays as NASA and Astrobotic investigate the failures and develop corrective actions.

In addition, VIPER long-lead acquisitions—such as the rover solar power array and avionics unit—have been affected by aerospace industry supply chain delays caused by COVID-19 as have delivery of computer boards and motor parts. Both of these issues have impacted design verification testing needed for the mission’s Critical Design Review, while COVID-19 also delayed some component development schedules.

Peregrine’s launch has been delayed by a year because Vulcan has been delayed because of Blue Origin’s problems with the BE-4 rocket engine. Though ULA hopes the Vulcan/Peregrine launch can occur late this year, that date remains very much in doubt. Further launch delays would thus threaten the launch of Griffin and VIPER.

As for the cost increases, the IG found that NASA had been forced to increase the budget for VIPER by 18.1%, a relatively minor increase compared to many of NASA’s other big projects. The IG noted however that further cost overruns are very possible, especially if the Peregrine mission experiences problems.

The photo above shows the rover’s presently planned route in the relatively flat area about 85 miles from the Moon’s south pole and near the western edge of Nobile Crater (pronounced No-BEEL-e).

Scientists decide propaganda and commercials are better than good research results

10:47 am

The on-going dark age: In a new study scientists have discovered that — instead of depending on hard research that is repeatedly confirmed by others — if they simply use a trusted spokesman in commercials promoting their work they can get people to accept their conclusions, at face value.

This momentous discovery occurred when some researchers decided to find out if putting Trump in a 30-second commercial asking people to get the COVID jab would encourage them to do so. This is what the test learned:

A creative effort to use former President Donald Trump to persuade people to get a COVID-19 vaccine shot appears to have paid off. An online advertisement created by a team of political scientists and economists that featured Trump recommending COVID-19 shots led to increased uptake of the vaccines in U.S. counties that had low vaccination rates, concludes a new analysis.

“We were so thrilled,” says Marc Hetherington, a political scientist at the University of North Carolina, Chapel Hill, who helped create the ad and co-authored the study. “How often do political scientists and economists do anything that helps the world? The answer is, like, 0% of the time.”

…The results highlight that “health communication needs to come from trusted messengers and to meet people where they are,” says behavioral scientist Katherine Milkman of the University of Pennsylvania, who was not involved in the study. [emphasis mine]

Hetherington’s highlighted quote was intended to imply that this research proved that political scientists and economists sometimes do do something that helps the world. I think it only proves that they never do.

Using advertising to sell a scientific conclusion is without doubt the most corrupt and idiotic method for selling a scientist’s work. It only proves the work itself, in this case the COVID shots, have questionable aspects that need propaganda to convince people of their value.

Other quotes from different scientists at the link also illustrate how divorced from actual research and data these scientists are. To their minds, the doubt that many people have of the COVID shots can only be attributed to an “antivaccine ecosystem” touting its own political agenda. The extensive research and data that suggests the shots carry risks while appearing possibly useless is either ignored by these scientists, or they are willfully ignorant of it.

Europe to put instrument on Japanese rover being launched and landed on the Moon by India

9:49 am

The new colonial movement: The European Space Agency (ESA) has signed an agreement with Japan’s space agency JAXA to put a science instrument on a Japanese rover that will be launched by India to the Moon and landed there on an Indian lander.

Under the deal, ESA would provide instruments for the Japanese rover, which would be used in the exploration of the Moon’s south pole under the mission targeted for 2024. … The lunar endeavour between the Indian Space Research Organisation (ISRO) and JAXA is called the Lunar Polar Exploration Mission (LUPEX) which aims to launch an Indian lander and a Japanese rover to the Moon.

In the next three years a lot of landers and rovers are planning to land on the Moon, most built by private American companies flying NASA and private payloads, but also joined by probes being sent by Russia, China, and now this Japanese-Indian-European mission. Even if only half succeed, the exploration of the lunar surface will still be quite busy.

Ukrainian rocket development for Nova Scotia spaceport unhindered by war

9:40 am

Capitalism in space: The development of a Ukrainian rocket dubbed Cyclone 4M for of any satellite customers who choose to launch from a planned Nova Scotia spaceport has not been delayed by the Ukraine war.

“Everything is stable with respect to our team in Ukraine,” said Steve Matier, president of Maritime Launch Services. “The facility there is fine, the staff is fine and at work. . . . We’re continuing to finance their development of the launch vehicle.”

The Cyclone 4M rocket Maritime Launch Services plans to use is designed and built by Ukrainian state corporations Yuzhnoye and Yuzhmash in Dnipro. Known as Space City, Dnipro is located in central Ukraine. The city of about a million people was shelled in mid-March by Russian forces and the airport runways and terminal were hit by missile strikes, according to Ukrainian government statements.

This story illustrates the strong possibility that the recent success the Ukraine has had on the battlefield has served to prevented any serious long term damage to its aerospace industry and its partners in the west. Those partnerships if anything look stronger, with the work in the Ukraine apparently able to continue as planned, with only slight delays.

Commercial Orbital Reef space station passes NASA’s design review

Proposed Orbital Reef space station

Capitalism in space: A proposed commercial space station dubbed Orbital Reef and being built by a partnership led by Sierra Space and Blue Origin has passed its NASA’s design review, allowing for construction to now begin.

The review, conducted as part of a $130 million development contract from NASA, found no issues with the station’s design.

This commercial partnership also includes Boeing, Redwire, Mitsubishi, Genesis Engineering, and Arizona State University, and plans its launch before 2030 when ISS will be retired. This quote from the article I think is important:

“We’re going as fast as we can,” Steve Lindsey, chief strategy officer at Sierra Space, said during a panel at the Goddard Memorial Symposium March 25. “We don’t want to have a gap like we did with crew back in the last decade.”

Three other private space stations are also under construction or being planned, all hoping to be operational prior to ’30. If even two of these launch, the 2030s will be very exciting indeed.

Astronomers discover a solar twin whose sunspot cycle changed into a grand minimum

9:19 am

Astronomers studying the sunspot cycle of several dozen stars that are twins of our Sun have identified for the first time a star whose 17-year cycle suddenly ceased, going into an extended grand minimum.

Comparing these stars to the Sun enables astronomers to better determine how typical – or not – the Sun is as a star. The Sun’s magnetic activity is defined by its 11-year sunspot cycle. Of the 59 stars that Baum’s team surveyed, 29 appeared to also have starspot cycles, and the period of those cycles could be measured for 14 of them.

“Of these 14 stars, the average length of their cycle is just under 10 years, which is similar to the Sun’s 11-year cycle,” Baum tells Physics World. However, not all the stars adhered to this time frame. One star that was surveyed has a cycle lasting less than four years, while another star, HD 166620, had a cycle 17 years long.

Note the past tense. Sometime between 1995 and 2004, HD 166620’s starspot cycle simply stopped.

When or if the star’s sunspot activity resume is unknown. The Sun’s last grand minimum, dubbed the Maunder Minimum, lasted 70 years during the 1600s.

No one yet understands why stars do this. This discovery however now shows that the Sun is not unique in this behavior.

Rocket Lab to attempt 1st stage recovery by helicopter on next launch

9:11 am

Capitalism in space: Rocket Lab will attempt during its next launch later this month to become the second commercial rocket company, after SpaceX, to successfully recover a first stage for reuse.

The company will use a customized Sikorsky S-92 helicopter to rendezvous with the stage as it descends slowly using parachutes and capture it. The helicopter will then fly it back to land and safely deposit it on the ground.

This launch is now scheduled for April 19th, at the earliest.

Ingenuity completes its 24th flight on Mars

9:14 pm

Overview map
Click for interactive map.

Ingenuity today completed its 24th flight on Mars, traveling a short 33 feet for 69.5 seconds in order to place it in a good position for an upcoming record-setting 25th flight.

With Flight 24 in our log book, it is now time to look forward to our upcoming effort that charts a course out of Séítah. Flight 25 – which was uplinked yesterday – will send Ingenuity 704 meters to the northwest (almost 80 meters longer than the current record – Flight 9). The helicopter’s ground speed will be about 5.5 meters per second (another record) and we expect to be in the rarefied Martian air for about 161.5 seconds.

The red dot on the map to the right indicates Perseverance’s present position. The green dot shows where Ingenuity landed today. The tan dashed lines indicate the planned routes for both. Ingenuity’s next flight will take it out of the rough terrain of Seitah and much closer to Three Forks.

Sonny & Cher – I Got You Babe

6:01 pm

An evening pause: This performance, from 1987, has some important historical background. As noted on the youtube page,

In November of 1987, Sonny Bono was running for mayor of Palm Springs and Cher was promoting her upcoming movie Moonstruck. The divorced couple went on Letterman together and were coaxed into playing ‘I Got You, Babe’ with Paul Shaffer and his band; they weren’t exactly the best of friends at this point, but both of them knew it would make for unforgettable television. Had YouTube existed back then, this would have gone insanely viral the next morning. It wound up being the final time they ever sang together, as Bono passed away in January 1998.
