More Boca Chica residents move out, accepting SpaceX offers

More Boca Chica residents have accepted SpaceX purchase offers, and are finding other places to live.

While not all are thrilled with the circumstances, the article suggests that there is far more good will then unhappiness. It appears the excitement of what SpaceX is doing, and its willingness to give these residents special viewing privileges in the future, has done wonders to ease the pain for many of them for having to sell their homes.

It has also produced youtube channels providing 24 hour live streams of SpaceX operations.

SpaceX recovers both fairing halves from Starlink launch

Capitalism in space: The two reused fairing halves that SpaceX used in yesterday’s Falcon 9 Starlink launch were both successfully recovered.

Starlink V1 L5 is now the second time ever that SpaceX โ€“ or anyone, for that matter โ€“ has successfully reused an orbital-class launch vehicle payload fairing, while the mission also marked the first time that SpaceX managed to recover a reused Falcon fairing. The burn from booster issues certainly isnโ€™t fully salved, as twin fairing catchers Ms. Tree and Ms. Chief both missed their fairing catch attempts, but both twice-flown fairing halves were still successfully scooped out of the Atlantic Ocean before they were torn apart.

The first reused fairing however was not recovered, making this recovery the first of used fairings. The company now has the ability to study them in order to better design future reusable fairings.

The article provides a lot of information about the difficulties of catching the fairings before they hit the water. It also notes that the reused fairings have all been fished out of the ocean, suggesting that in the end catching them in the ship’s nets will be unnecessary.

NASA confirms May target date for first manned Dragon flight

Capitalism in space: In announcing today it is beginning media accreditation for SpaceX’s first manned Dragon flight to ISS, the agency confirmed earlier reports from SpaceX that they are now aiming for a mid-to-late May launch.

Much can change before then. COVID-19 could get worse, shutting down all launches. The engine failure on yesterday’s successful Falcon 9 launch could require delays.

However, right now, things look good for May, which will be the first time since 2011 that Americans will launch from American soil on an American-built rocket, an almost ten year gap that has been downright disgraceful. Thank you Congress and presidents Bush and Obama! It was how you planned it, and is also another reason we got Trump.

NASA’s inspector general finds more budget overruns at Artemis

A new report [pdf] released today from NASA’s inspector general has found more budget overruns and managerial issues relating to developing the ground software required by both Orion and SLS.

There are two software components involved, called SCCS and GFAS for brevity. This report focuses on the latter. A previous report found that “SCCS had significantly exceeded its initial cost and schedule estimates with development costs increasing approximately 77 percent and release of a fully operational version of the software slipping 14 months.” According to that previous report [pdf], that increase went from $117 million to $207 million.

As for GFAS:

Overall, as of October 2019 GFAS development has cost $51 million, about $14 million more than originally planned.

This report, as well as yesterday’s, are quite damning to the previous management of NASA’s manned program under Bill Gerstenmaier. It appears they could not get anything done on time and even close to their budget.

It also appears to me that the Trump administration has removed the reins from its inspector general offices. During the Obama administration I noticed a strong reticence in IG reports to criticize government operations. Problems as outlined in both yesterday’s and today’s reports would have been couched gently, to obscure how bad they were. Now the reports are more blunt, and are more clearly written.

Also, this sudden stream of releases outlining the problems in Artemis might be part of the Trump administration’s effort to shift from this government program to using private commercial companies. To do this however the administration needs Congressional support, which up to now has strongly favored funding SLS and Orion. Having these reports will strengthen the administration’s hand should it propose eliminating these programs, as it is now beginning to do with Gateway.

French and American studies find drug that can treat COVID-19

It isn’t a vaccine that will prevent infection, but tests in France and in the U.S. now show that a drug normally used to treat malaria is very effective in reducing the symptoms of the Wuhan virus.

He said that the first Covid-19 patients he had treated with the drug chloroquine had seen a rapid and effective speeding up of their healing process, and a sharp decrease in the amount of time they remained contagious.

Chloroquine – which is normally used mainly to prevent and treat malaria – was administered via the named drug, Plaquenil.

The drug is readily available and can be prescribed to anyone who is considered threatened by the virus to help them get better why reducing the chances of them giving it to others.

Apollo 15 command module pilot Al Worden passes at 88

Their numbers slowly shrink: Al Worden, who orbited the Moon as commander of the Apollo 15 command module, has passed away at the age of 88.

For three days in 1971, Worden circled the moon as Dave Scott and Jim Irwin worked on the lunar surface โ€” including driving a rover for the first time. Being a command module pilot has been called the loneliest job in humanity. In the spacecraft alone, not able to talk to anyone when the capsule was on the back side of the moon. But Worden told NPR in a 2016 interview, “I was pretty comfortable with being by myself.”

After Scott and Irwin returned from the lunar surface and the crew was on its way back home, Worden conducted a spacewalk, the first ever in deep-space. He ventured outside the capsule to retrieve film from the scientific cameras.

The link is to an NPR obituary, so of course it makes a big deal about the effort by the astronauts to make some extra money by selling postage stamp covers that they bought with them post-flight.

Worden remembers it this way, “Jim and I were told that this was something that happened on every flight. No big deal. Well, it turned out to be a huge deal.” Even though previous crews had profited off lunar souvenirs, it became a public relations nightmare for NASA. The three astronauts never flew again. Worden said he regretted what happened: “I think the flight speaks for itself. I think the science that we did on the flight speaks for itself.”

I always thought it was quite offensive that the American government, the press, NASA, and the public took offense then about this. These guys were not paid that much, slightly above an ordinary middle class salary, for doing something totally unique and incredibly dangerous. If they had a chance to make some extra cash on the side, all power to them.

This was just after the 1960s, however, and private enterprise and commercial profit was steadily going out of fashion. We as a culture had bought into the Soviet model of top-down government programs that were centrally controlled. For any of the individuals involved to make some independent cash for themselves was considered crass and corrupt.

Regardless, God speed, Al Worden.

Comet C/2019 ATLAS brightening

Comet ATLAS, discovered in 2019 by a telescopic survey looking for near Earth asteroids, is brightening more than expected as it approaches the Sun, and could by May be visible to the naked eye.

Jonathan Shanklin, Director of the British Astronomical Associationโ€™s Comet Section, reports that the current comet, C/2019 Y4, brightened quite rapidly in mid February, and adds โ€œas of March 11 there is no sign of a slowdown in the rate of brightening. It is already visible in large binoculars . . . The uncertainty in brightness at the time of perihelion is large, though the worst case indicator is 2nd magnitude. It will remain well placed for UK observers into May and could become a prominent object.โ€

If 2nd magnitude is the dimmest they presently expect, this comet will be one of the brightest objects in the sky come May. Stay tuned!

Wednesday at the non-existent Lunar & Planetary Science Conference

The Moon's south pole

My virtual coverage of the cancelled 51st annual Lunar & Planetary Science conference continues today with a review of the abstracts of presentations that were planned for today, but unfortunately will never be presented.

As a side note, the social shutdown being imposed on America due to the panic over COVID-19 has some side benefits, as has been noted in a bunch of stories today. Not only will this possibly destroy the power the left has on college campuses as universities quickly shift to online courses, it will also likely put an end to the endless science conferences that are usually paid for by U.S. tax dollars. (That cost includes not just the expense of the conference, but the fees and transportation costs of the participants, almost all of whom get the money from either their government job or through research grants from the government.)

Anyway, for good or ill, the virus shut down the planetary conference in Texas this week, forcing me to post these daily summaries based not on real presentations where I would have interviewed the scientists and gotten some questions answered, but on their abstracts placed on line beforehand. Today, the three big subjects were the south pole of the Moon (as shown in the map above from one abstract [pdf], produced by one instrument on Lunar Reconnaissance Orbiter [LRO]), the Martian environment, and Titan. I will take them it that order.

Secondary impacts in water ice on Mars

Secondary impact in water ice on Mars
Click for full resolution image.

Cool image time! Today the science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) released a beautiful captioned image of a secondary impact of an object into the icy plains of Utopia Planitia, the northern lowlands northeast of where the rover Perseverance will land in 2021. The image to the right, cropped and reduced to post here, shows one of several secondary craters in the full image. As planetary scientist Alfred McEwen explains in the caption,

One interpretation [for the crater’s unusual appearance] is that the impact crater exposed nearly pure water ice, which then sublimated away where exposed by the slopes of the crater, expanding the craterโ€™s diameter and producing a scalloped appearance. The small polygons are another indicator of shallow ice.

Note the dunes at the bottom of the crater. This has become a trap of wind-blown sand and dust. Note also how this secondary impact gives us a rough idea of the thickness of this ice, based on the area sublimated away.

There is a lot of relatively accessible ice in those northern lowlands, which is why SpaceX likes them for its possible landing site for Starship. That candidate site is in Arcadia Planitia, on the other side of Mars, but it is still in these same northern lowlands, where scientists have found lots of evidence of buried ice.

More overruns in NASA’s SLS program, this time with the mobile launchers

A new inspector general report [pdf] has found massive cost overruns in NASA over the building of the two mobile launch platforms the agency will use to launch its SLS rocket.

The original budget for the first mobile launch was supposed to be $234 million. NASA has now spent $927 million.

Worse, this platform will see limited use, as it was designed for the first smaller iteration of SLS, which NASA hopes to quickly replace with a more powerful version. Afterward it will become obsolete, replaced by the second mobile launch platform, now estimated to cost $486 million.

That’s about $1.5 billion just to build the launch platforms for SLS. That’s only a little less than SpaceX will spend to design, test, build, and launch its new Starship/Super Heavy rocket. And not only will Starship/Super Heavy be completely reusable, it will launch as much if not more payload into orbit as SLS.

But don’t worry. Our geniuses in Congress will continue to support SLS no matter the cost, even if it bankrupts NASA and prevents any real space exploration. They see its cost overruns, long delays, and inability to accomplish anything as a benefit, pumping money into their states and districts in order to buy votes.
