Commercial Orbital Reef space station passes NASA’s design review

9:30 am

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.

NASA postpones next SLS dress rehearsal countdown attempt to next week

11:06 pm

NASA officials today said that they have postponed their next attempt to complete the first dress rehearsal countdown of the SLS unitl next week, thus allowing the private commercial manned Axiom launch to ISS to proceed on April 8th.

The rocket will remain at the launch site as the engineering teams assess the issues that caused two scrubs and several launch count down holds.

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.

Today’s blacklisted American: Whites aggressively blocked from attending health dept meeting

1:14 pm

Jim Crow celebrated in Seattle!
The return of Jim Crow, this time celebrated in the north, in Seattle!

“Segregation today, segregation tomorrow, segregation forever!” Seattle health administrators purposely organized an employee Zoom training session for minorities only, then aggressively banned any white staffers from attending, and then lied repeatedly about their actions and the segregated and illegal nature of the session.

The subject of the session was in itself bigoted, as it made the claim that dieting is a white racist strategy to harm blacks.

The King County Department of Human Resources announced the remote workshop, “Anti-Blackness and Diet Culture,” in an all-staff email newsletter. It was part of the county’s Balanced You program, which focuses on staff wellness. Tacoma-based Liberating Jasper, which conducted the workshop, claims dieting is harmful to black people, and that “Western ideals of attractiveness and health are steeped in whiteness.” It even implies that obesity can be healthy.

Despite claims to the contrary, the workshop intentionally excluded white people. Indeed, the event was promoted both publicly and privately for “BIPOC employees only.”

For those not educated in the left’s alphabet lexicon of races and genders, BIPOC stands for blacks, indigenous people, and people of color. It is designed to create a group of favored minorities while excluding the sexual perverse, which in other contexts the left will gladly celebrate.

What makes the story especially offensive is not this bigoted session and the desire to ban any whites from attending, but the extent in which government officials repeatedly lied about their intentions to discriminate against whites. This story was revealed by Seattle radio host Jason Rantz. Over and over again his office would challenge officials, who would make some absurd claim, and over and over again Rantz would prove this an outright lie, using internal emails obtained by Rantz’s investigation.

For example, one white attendee was specifically removed from the Zoom meeting because of his race.

Looking down into a Jupiter hurricane

Looking down into a Jupiter hurricane
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was created by citizen scientists Kevin Gill and Navaneeth Krishnan from a raw image taken by Juno during its 40th close fly-by of Jupiter in February 2022.

I don’t have a scale, but I would guess that this storm is at least a thousand miles across. The depth is harder to measure, but we looking down into a deep whirlpool for sure.

To bring out the details Gill and Krishnan enhanced the colors significantly. The original is quite bland in comparison, with this storm being the faint dark spot just below the center near the photo’s left edge.

UAE wants to prioritize private enterprise for its space effort

10:17 am

Capitalism in space: According to officials of the United Arab Emirates (UAE) space agency, that nation is working to encourage the growth of a private space industry, funded initially using government money, in its effort to become a major world player in space.

“We’ve spent well over Dh1.5 billion ($408 million) on building capacity within the space industry over the last eight years and we’re more than doubling that over the next decade.”

Laws and regulations, including permits, which would allow interested companies to set up base in the UAE, are already available through a space law passed in 2019.

Companies would also have access to funding from a new initiative launched by the space agency, called Space Analytics and Solutions, which has a budget of Dh20 million. The programme aims to help start-ups build space-based applications that focus on food security, climate change, infrastructure and the oil and gas industry.

The space agency hopes that as these companies progress, they would become less reliant on government funding.

While the UAE’s Al-Amal Mars orbiter was mostly built and launched by foreign companies, it hopes its next major mission, to send an unmanned probe to seven asteroids, will be built almost entirely by companies run by UAE citizens, something they claim they have achieved with an upcoming smallsat Earth observation satellite.

The article also mentioned as an aside that the UAE has ended its 2019 agreement with Virgin Galactic to allow it to launch from the UAE. Instead, it is negotiating with Blue Origin “to set up spaceports.”

More than 4,000 people apply to Japan’s JAXA space agency to become astronauts

10:05 am

In its first new recruitment effort in thirteen years, JASA has received more than 4,000 applications from people eager to become astronauts flying to ISS.

A record number of people applied as the Japan Aerospace Exploration Agency for the first time dropped the requirement that candidates have a university education. The change was made in the hope of recruiting people with a wide range of experience.

However, applicants were required to have at least three years of work experience as of late March, with some academic qualifications being considered as meeting this requirement.

It is unfortunate that the Japanese people do not have more options to get into space. They must either buy a flight from foreign private companies, or depend on a government agency to approve them.

Rogozin proposes Russia launch modules to China’s space station

9:54 am

Dmitry Rogozin, the head of Roscosmos, yesterday proposed in an interview on China’s state-run press that Russia is eager to discuss the possibility of attaching its future space station modules to China’s Tiangong space station.

“As for the Chinese space station, we can discuss construction of some joint modules as well. In order to be friends in space, friendship must first be established back on Earth, and Russia and China are friends on Earth,” Rogozin said. He opined that Russia and China “can be together” in human spaceflights as well.

Whether China will agree is in some ways besides the point. The real question is whether Russia has the capability to do this. Though China and Russia already have a joint agreement to develop a permanent base on the Moon, China is carrying most of the load. Moreover, Russia’s new modules for ISS are decades behind schedule. Whether they will now even be launched to ISS is questionable. Adding these Russian modules to China’s space station will require some major engineering discussions, as neither Tiangong nor the modules were designed for such a thing.

I suspect the two countries will work out an agreement that they will announce with great fanfare. I also expect China will insist that at no time will it be dependent on Russian technology, so that if Russia is delayed or can’t get it done, China will not be hampered in any way. This is essentially their deal for building the lunar base.

Amazon announces launch agreements with Blue Origin, Arianespace, and ULA

9:42 am

Capitalism in space: Amazon today announced major multi-launch agreements with Blue Origin, Arianespace, and ULA to launch its 3,000+ Kuiper satellite constellation.

According to the press release, ULA won 38 launches using its new Vulcan-Centaur rocket (not yet flown), Arianespace won 18 launches using its new Ariane-6 rocket (not yet flown), and Blue Origin won 12 launches using its new New Glenn rocket (not yet flown), with an option for 15 more. The ULA deal is in addition to a previous launch contract of nine launches using the Atlas-5 rocket.

In addition, Amazon hopes to launch two prototype satellites later this year using ABL’s smallsat RS1 rocket (not yet flown).

Overall, this Amazon launch announcement might be the largest launch contract deal ever. However, the company’s reliance on unproven rockets means it will also likely face some delays and failures in its early stages. That the press release makes no mention of any schedule for launches illustrates this fact starkly. All four rockets have already seen major delays. with the three biggest (Vulcan-Centaur, New Glenn, Ariane 6) now more than two years behind schedule, and the likelihood of their first launch occurring in 2022 increasingly unlikely.
