Curiosity celebrates ten years on Mars

9:31 am

Curiosity's location in Gale Crater

Sometime today the rover Curiosity will celebrate its tenth anniversary on Mars. The oblique graphic of Gale Crater above, first released by the science team shortly before landing in 2012, has been further annotated with a red line to show the rover’s journey since then. As noted by Scott VanBommel, Planetary Scientist at Washington University, today on the science team’s blog:

As we the science and engineering teams have aged this last decade, so has Curiosity. The toll of ten years and nearly 28.5 km [17.7 miles] of Mars driving shows with every MAHLI wheel imaging activity, with less energy available for a plan, and with aging mechanisms. This is the life of a Mars rover. Spirit and Opportunity were no different, yet they persisted and paved the way scientifically and technologically for the rovers of today. Curiosity has made numerous scientific discoveries during these ten years, emphasized by the over 500 science team publications, with many more ahead as we continue our ascent and exploration of Gale crater and Mount Sharp.

I look forward to the next ten years.

Despite that aging, Curiosity’s general condition appears quite excellent, with its wheels the greatest concern but generally holding up. Based on the last ten years, the rover is likely to remain operational for at least ten more years, if not longer.

In the more immediate future, the rover is only days away from getting its first good look down into Gediz Valles, that canyon on the graphic above that it has been traveling towards since day one.

A good review of five of Curiosity’s biggest discoveries using its sample analysis instrument can be found here.

Virgin Galactic once again delays commercial suborbital operations

9:08 am

Capitalism in space: In releasing its quarterly report, Virgin Galactic yesterday revealed that it is once again delaying the start of commercial suborbital operations, pushing back from the first quarter of 2023 to the second quarter.

In an earnings call, company executives said that the latest delay was not directly related to supply chain and staffing problems it blamed for the previous delay. Instead, refurbishment work on its WhiteKnightTwo plane, VMS Eve, was taking longer than planned. “The driver is around the amount of time it is taking us to accomplish the work scope on Eve,” said Michael Colglazier, chief executive of Virgin Galactic. “We did not plan the full amount of time that’s been needed to get this work accomplished.”

Company officials also said they are shifting its customer emphasis, now focusing much more on “private and government researchers.” Let me translate: The public is not buying tickets, so Virgin Galactic hopes to convince the government to keep it afloat instead.

I predict this company will likely never fly any customers, and it appears the stock agrees, with the stock plunging in value, from $8.25 to $6.95 in less than a day.

Astra cancels all launches with its Rocket 3.3 rocket

9:01 am

Capitalism in space: Astra yesterday announced that it has canceled all further launches with its Rocket-3.3 rocket, and will instead focus on developing a larger version, dubbed Rocket-4, which it says will begin test flights in 2023.

The company says that it will no longer fly the Rocket 3.3 and move on to its larger Rocket 4 vehicle that it announced in May. One change is that the payload performance of the new rocket has doubled to 600 kilograms. Kemp didn’t disclose details of the design change other than an upgrade to its upper stage engine. Rocket 3.3, by contrast, had a payload capacity of no more than 50 kilograms.

“The feedback that we were getting from some of the larger constellation operators was that satellites were getting larger,” he said. Discontinuing the existing Rocket 3.3, he said, allowed the company to focus its resources on the new launch system, including increasing its payload capacity.

Essentially, Astra has left the field and is at present no longer an operational smallsat rocket company. It is also likely that its announced schedule for its upgraded rocket will not be met. Thus, expect customers to shift to other launch providers able to launch satellites, such as Rocket Lab and Virgin Orbit.

Not surprisingly, the company’s stock plunged soon after this announcement.

SpaceX launches South Korea’s Danuri lunar orbiter

4:50 pm

SpaceX today successfully launched South Korea’s Danuri lunar orbiter, also called the Korea Pathfinder Lunar Orbiter.

The first stage completed its sixth flight, landing on a drone ship in the Atlantic. The fairings completed their fourth flight.

Danuri is now on its way to the Moon, with a planned arrival in lunar orbit on December 16, 2022. It carries six instruments, one of which was developed by NASA. The spacecraft, while designed to study the Moon, is primarily a technology test mission laying the groundwork for more sophisticated interplanetary South Korean missions. More information about the mission can be found here.

The leaders in the 2022 launch race:

34 SpaceX
28 China
10 Russia
6 Rocket Lab
5 ULA

The U.S. now leads China 49 to 28 in the national rankings, and the entire world combined 49 to 45. With this launch American private enterprise has now surpassed the entire launch total for all of 2021, and has the most launches for the U.S. since 1967, when it completed successfully 57 launches.

China launches “reusable experimental spacecraft”

4:02 pm

According to the official Chinese press, China today successfully used its Long March 2F rocket to place into orbit a “reusable experimental spacecraft.”

To say the information provided was terse is to be extravagant. This is it:

After a period of in-orbit operation, the spacecraft will return to its scheduled landing site in China. It will test reusable technologies and in-orbit service technologies as planned during its flight, providing technological support for the peaceful use of space.

It appears, based on the size of the rocket, that this spacecraft is likely a copy of Boeing’s X-37B.

The leaders in the 2022 launch race:

33 SpaceX
28 China
10 Russia
6 Rocket Lab
5 ULA

The U.S. still leads China 48 to 28 in the national rankings, and the entire world combined 48 to 45.

These numbers should change within the next half hour, as SpaceX is about to launch another rocket.

Glacial flows pushing out through a Martian crater rim

12:51 pm

Wider view of 6-mile-wide crater
Click for full image.

Today’s cool image once again illustrates how Mars is far from a waterless planet. Instead, there is strong evidence that water ice can be found across most of the Red Planet’s surface, excluding the equatorial regions lower than 30 degrees latitude.

The photo to the right was taken on September 11, 2021 by the wide view context camera on Mars Reconnaissance Orbiter (MRO). It shows a 6-mile-wide unnamed crater on Mars, located at 35 degrees south latitude, with what appears to be a glacier in its interior, flowing to the southwest towards several breaches in the crater’s southwest rim. Several of those breaches now sit higher than the flow, suggesting that the glacier itself was once higher and flowed out of those gaps. Now the level has dropped, and the only place the glacier exits the crater is the central gap at the center of the white rectangle.

That white rectangle marks the area covered by a recent MRO high resolution image, taken on March 29, 2022 and cropped and reduced to post below.

Today’s blacklisted American: Supreme Court Justice Thomas forced to quit as lecturer at GWU

11:40 am

Clarence Thomas: Banned at amazon
Supreme Court Justice Clarence Thomas: driven out
as a lecturer at George Washington University

Blacklists are back and our future law students love ’em: Faced with a petition signed by 11,000 individuals demanding he be fired, Supreme Court Justice Thomas has resigned as a lecturer at George Washington University (GWU).

Thomas has been a lecturer at the school since 2011, but has now been removed as faculty from its website. His decision not to return to teaching comes in the wake of protests against conservative supreme court judges following the overturning of Roe v. Wade in June 2022.

The school was hit by a petition calling for the removal of Thomas, with more than 11,000 signatories. But George Washington University is home to just 1,600 students, and bosses there defended Thomas, insisting he was entitled to his views. [emphasis mine]

The highlighted words illustrate something significant: The bulk of the petition’s signers were not from George Washington University. However, though the school had apparently supported Thomas during this affair, we do not know how many of its 1,600 students signed the petition. What we do know is that there did not seem to be much public support for him from those students.

It is hard to fathom any law student not wanting to meet in person and hear the legal opinions of a Supreme Court justice, no matter where he or she stands on the political spectrum. To try to block such lectures reveals a shocking close-mindedness and hostility to rational thought. The language of the petition illustrates this, filled with false statements, ad hominen attacks, and complete intolerance of other points of view:

Axiom signs deal with New Zealand

9:52 am

Capitalism in space: The private space station company Axiom has now signed a deal with New Zealand to permit its citizens to propose and fly experiments on future Axiom missions, both to ISS and to Axiom’s own space station, scheduled for launch beginning in ’24.

This is the fourth international commercial agreement Axiom has signed since May, with Italy, Hungary, and the UAE the signatories in the previous deals. The UAE deal also included the launch of a UAE astronaut to ISS for a six month flight.

Axiom hopes to launch its first module to ISS in ’24, with later modules eventually allowing it to undock its section to fly as an independent station when ISS is retired.

Environmentalists opposed to Starship at Boca Chica appeal dismissal of their lawsuit

9:45 am

Environmentalists from the Sierra Club and one Texas Indian tribe have now appealed the dismissal of their lawsuit aimed at blocking further tests or launches of Starship and Superheavy by SpaceX at its Boca Chica facility.

The Sierra Club and the Carrizo/Comecrudo Tribe of South Texas jointly appealed the 445th District Court’s decision July 7 to dismiss a lawsuit concerning SpaceX testing of its next-generation Starship vehicle closing nearby Boca Chica Beach, the coalition said July 28. In the dismissal, Judge Gloria Rincones argued there is “no private right of enforcement” concerning the beach access, according to KRGV.com (opens in new tab). The dismissal took place over the appellants’ protests that closing the beach violates the Texas state constitution, along with access rights by traditional groups.

The Sierra Club’s Brownsville organizer, Emma Guevara, stated the appeal is taking place because the beach is closed weekly to allow “a billionaire [to] launch deadly rockets near homes and wildlife.”

Citing a fireball that briefly and unexpectedly engulfed Starship during testing July 12, Guevera said her family was “forced” to hear the noise, which “launched without any warning for the public.” [emphasis mine]

My my, what a horror! I suppose everyone must stop what they are doing because Guevera and his family might be inconvenienced. And who cares if the lawsuit prevents thousands of south Texas citizens from having jobs and a thriving economy? It is more important Guevera doesn’t have to hear loud noises.

The lawsuit claims that allowing SpaceX to periodically close access to the nearest beach violates the state’s constitution, despite laws passed by both the local and state legislatures allowing for these closures.

Next private SpaceX manned targeting December launch

9:31 am

Capitalism in space: SpaceX is now planning to launch in December the next private manned Dragon orbital mission, dubbed Polaris Dawn, and led by billionaire Jared Isaacman, who led the previous private Inspiration4 mission in September 2021.

Polaris Dawn is the first of three separate crewed launches, all of them funded by Isaacman. This first effort will see Isaacman flying a SpaceX Dragon spacecraft alongside Sarah Gillis, Anna Menon and Scott Poteet. (Both Gillis and Menon work at SpaceX.) The second launch aims to use a Dragon while the third is scheduled as the first crewed mission for Starship, SpaceX’s next-generation spacecraft.

…Among the mission’s aims is the first spacewalk, or extravehicular activity (EVA), of a private astronaut. The crew will use SpaceX-developed EVA suits for the effort. Crew Dragon will be depressurized for the spacewalk in a similar way that NASA’s Gemini capsules were in the 1960s, requiring all crew members to wear suits designed for a vacuum environment.

By not flying to ISS, Isaacman and SpaceX avoid the high fees NASA charges as well as its extensive requirements.

By remaining in orbit however the length of the mission will be limited to only a few days, rather than weeks. Thus, it underlines the growing need for private commercial space stations, not controlled by the government.
