Another airplane journey, another idiotic example of the stupidity of the Transportation Security Agency (TSA).
I am in the airport in Panama City, Florida, waiting for my flight home. As I was putting my shoes and belt back on at the security conveyor belt, I watched as an older couple was having their carry-on bags opened and inspected. The woman was wearing an Islamic scarf. (Despite this I am sure neither posed any threat, because both were somewhat elderly, and had been given passes that I think signified this, since anyone over 75 years old is allowed to keep shoes and belts on.)
What was amazing to me was what happened when the TSA officer discovered that the women had brought a take-out lunch with her, as well as a full set of metal silverware to eat it. The officer hardly glanced at silverware, seeming more interested in her lunch in a plastic food container. While he inspected this the woman put the silverware back in her purse, and after the officer was satisfied that the take-out food was not dangerous, he allowed them to leave, silverware and all.
As they left I was right there, putting my wallet and keys back in my pockets, with that officer only about two feet away. I couldn’t help it. I said, “Excuse me, it is now permissible to bring metal silverware, forks, knives, so forth, on an airplane?”

TESS, in orbit and designed mostly to detect transiting exoplanets has spotted a black hole as it tour an orbited star apart.
The video at the link provides a nice summary and explanation, include a cool compute simulation of what the event looked like.
The Curiosity science team has decided to use the first of its nine “wet chemistry cups” to test a recently obtained Martian drill sample for organic material.
Searching for organic molecules in rocks on Mars is no easy task. Curiosityโs Sample Analysis at Mars (SAM) instrument is designed to analyze the chemical composition of gases, which it creates by slowly heating rock samples in an oven. The volatile gases that are driven off the heated rock sample get sent to SAMโs gas chromatograph and mass spectrometer (GCMS), which can identify the different gaseous compounds. However, organic molecules are tough to detect with this technique, because instead of transforming straight into gases when heated, they can decompose into simpler molecules.
But if organic molecules are “derivatized” before theyโre heated โ meaning that they react with other chemicals first in order to become more volatile โ then the compounds are more likely to enter the GCMS without breaking down, and SAM has a better chance of detecting them. This derivatization process uses solvents of chemicals, so we call it a “wet chemistry” experiment. Curiosity only has nine cups containing these solvents, so we are careful to save our wet chemistry experiments for only the most interesting rock samples.
The “Glen Etive” site, which we have been studying for the past month, is enticing enough for this special experiment!
They are performing this operation today. This is a big deal, because they only have nine of these cups. They have been saving them for the right time, and when the drill had problems two years ago and looked for awhile like it would never work again, they were horrified at the possibility they would never get to use them at all. While I would not be surprised if NASA issues a press release today touting this decision, do not expect any announcement of results for quite awhile, as I suspect the scientists in charge will want to publish their paper on the subject first.
This location, in the clay unit in the foothills of Mount Sharp, is a spot where they have drilled twice, as shown by the two drill holes visible near the center of the the picture above.
Capitalism in space: Bob Smith, the CEO of Blue Origin, revealed this week that the first manned flights of its reusable suborbital New Shepard spacecraft will likely not happen in 2019, as previously announced.
Blue Origin, which is headquartered in Kent, Wash., has filed plans with the Federal Communications Commission for at least two more New Shepard test flights from its test and launch facility in West Texas. These would be the 12th and 13th flights of the New Shepard test program.
On Tuesday, Blue Origin sought reauthorization of the next test flight for a six-month period running from Nov. 1 to next May. The existing authorization is set to expire on Dec. 1, which suggests that the company wants to reserve more time to prepare for the test.
Whether those next two test flights will use the capsule they have flown previously, or a new capsule, dubbed “RSS First Step”, that they intend to put the first people on, could determine how much of a delay to expect. That new capsule is built but it has never flown. If the next two flights use the previous test capsule, this would guarantee even more delays before Blue Origin flies people.
Russia today completed its second Soyuz launch in twenty-four hours, launching the third in a constellation of military satellites designed to detect incoming missiles.
With this launch Russia has topped its total from 2018, and looks very likely finish the year with the most launches since 2016.
The leaders in the 2019 launch race:
18 China
16 Russia
10 SpaceX
6 Europe (Arianespace)
The U.S. continues to lead China 19 to 18 in the national rankings.
Capitalism in space: Spacebit, a United Kingdom company, has signed a deal to put an instrument on Astrobotic’s first lunar lander, Peregrine-1, set for launch by 2021.
Astrobotic was one of the three private companies awarded NASA contracts to build unmanned lunar landers to carry NASA instruments to the Moon. In addition, these companies could sell additional space to other private companies. According to the press release, Astrobotic already has a manifest of sixteen such contracts.
One of the last few commercial launches for Russia’s Proton rocket has been delayed because the satellite “was not attached correctly to the upper stage.”
This is likely not as serious a blunder as the story makes it sounds. They had detected some “electromagnetic interference” in the upper stage’s control system during prechecks, which suggests a wire got crossed somewhere.
Three launches today, by China, Japan, and Russia. China launched a Yunhai-1 weather satellite using its Long March 2D rocket. Japan in turn successfully launched, on its second attempt, its HTV cargo freighter to ISS. This was Japan’s second launch this year.
Finally, Russia has just successfully put three astronauts into orbit using its Soyuz rocket, including the first astronaut of the United Arab Emirates.
The leaders in the 2019 launch race:
18 China
15 Russia
10 SpaceX
6 Europe (Arianespace)
The U.S. lead over China in the national rankings is now 19 to 18.
Capitalism in space: Virgin Orbit has shipped its first LauncherOne rocket to Mohave for final tests prior to its first launch, planned for sometime this year.
Virgin Orbit didnโt give a schedule for completing those tests and performing that orbital flight. Dan Hart, president and chief executive of Virgin Orbit, said at the World Satellite Business Week conference in Paris Sept. 11 that he expected those final tests be completed in a matter of weeks. โIt will take a handful of weeks to get through a number of wet dress rehearsals, crew training, and verification of the system,โ he said. โWeโll do one flight test with that rocket and then weโll get to orbit.โ He estimated the company would be ready for launch โin the middle of this fall.โ
If that first orbital test flight is successful, they hope to do their first operational commercial launch before the end of the year.
My 2016 prediction that a LauncherOne will complete its first commercial launch before SpaceShipOne, continues to look likely, even though SpaceShipOne began development more than a decade before LauncherOne..
According to one astronomer in a paper published this week, the most likely place to find alien artifacts would be on the co-orbital asteroids, objects whose orbit is very similar to the Earth and thus always nearby but mostly unseen.
In this context, a co-orbital is an asteroid that goes around the Sun on the same, or similar, orbital path to Earth. Co-orbital objects approach Earth very closely every year at distance is much shorter than anything except the moon.
Consequently, co-orbitals could be a great place to watch Earth from. Not only would any alien probes on co-orbital objects be concealed, but they would also be anchored and able to access solar energy. They could possibly sustain themselves for many thousands of years.
According to this paper, if aliens have visited the solar system in the past they would place their long-term alien probes on such an asteroid, or even give it a comparable co-orbit. And if we look and don’t find anything, that would strongly imply that we are alone in the universe.
Fun stuff, but need I say that not finding alien artifacts at these locations proves nothing.
Hat tip Jeff Bliss.
Because the comet that amateur astronomer Gennady Borisov discovered in August is actually the second interstellar object ever discovered that is entering the solar system, the International Astronomical Union (IAU) has decided to dub it 2I/Borisov, honoring its discoverer as is traditional with comets but indicating its interstellar nature in the name.
The orbit is now sufficiently well known, and the object is unambiguously interstellar in origin; it has received its final designation as the second interstellar object, 2I. In this case, the IAU has decided to follow the tradition of naming cometary objects after their discoverers, so the object has been named 2I/Borisov.
As my regular readers know, I am not a fan of the IAU’s effort to claim the right to name every object in the universe. In this case it has at least made the proper decision.
Capitalism in space: In a tweet on September 22 Elon Musk gave an update on the status of its Starship rocket.
His tweet provided a picture of crews attaching “rear moving fins” the what they are now calling Starship Mk1.
The photo showed the stainless steel hull of the rocket as SpaceX attached two large fins to the base. Starship is a massive, next-generation vehicle that Muskโs company is building to send cargo and as many as 100 people to the moon and Mars.
Musk is expected to make a major speech on September 28 on Starship’s status.
I am presently winging my way to Panama City, Florida, to give two different lectures at the Doolitte Institute tomorrow. More information on each are here and here
Posting will continue, but be somewhat intermittent.

The never-ending boondoggle: NASA today awarded Lockheed Martin a long term contract to build as many as twelve future Orion capsules.
OPOC is an indefinite-delivery/indefinite-quantity contract that includes a commitment to order a minimum of six and a maximum of 12 Orion spacecraft, with an ordering period through Sept. 30, 2030. Production and operations of the spacecraft for six to 12 missions will establish a core set of capabilities, stabilize the production process, and demonstrate reusability of spacecraft components.
โThis contract secures Orion production through the next decade, demonstrating NASAโs commitment to establishing a sustainable presence at the Moon to bring back new knowledge and prepare for sending astronauts to Mars,โ said NASA Administrator Jim Bridenstine. โOrion is a highly-capable, state-of-the-art spacecraft, designed specifically for deep space missions with astronauts, and an integral part of NASAโs infrastructure for Artemis missions and future exploration of the solar system.โ [emphasis mine]
I honestly don’t know how NASA can commit to building these Orion capsules, when Congress has yet to fund them. I guess NASA has decided that Congress and elections are irrelevant, that they — as our anointed rulers in Washington — can make these decisions unilaterally, at their own whim.
One quote in the press release really stood out to me:
โAs the only vehicle capable of deep space exploration, the Orion spacecraft is critical to Americaโs continued leadership,โ said Rep. Brian Babin [R-Texas].
What a crock. Orion is pork, period. It is simple too small for any deep space mission, no matter what lies NASA tries to tell us. It will get us nowhere.
All this contract does is justify the existence of the Johnson Space Center, which really has no purpose since the retirement of the shuttle and the decision to fly future astronauts on privately built spacecraft. Having Orion to “manage” will convince people that the workers at Johnson are doing something, when really almost everything of importance will be done by Lockheed Martin.
This contract is also another component in NASA’s political strategy to get as many players in the space business committed to both Artemis and Gateway. Pretty soon they will have everyone on board, with big tax dollar bribes.
Meanwhile, what they are building won’t accomplish anything, and will strand us in lunar orbit for decades, while other countries land and learn how to build bases on other worlds.
Cool image time! I could also call this another example of mass wasting, which it appears to be according to my understanding of Martian geological processes. However, the Mars Reconnaissance Orbiter science team dubbed this image “Tongue-Shaped Glaciers in Centauri Montes,” and I have no right to disagree with them.
The image to the right, rotated, cropped, reduced, and brightened to post here, shows the most prominent tongue-shaped glacier in the full image. The two curved ridges to the south of the glacier’s tip are almost certainly old moraines of debris pushed there during earlier events, when the glacier material extended farther out. In fact, if you look close you can see that this tongue lies on top of a larger older tongue that lines up with the closer of these two ridges.
This feature is located at 37 degrees south latitude, which puts it inside Mars’s southern glacial band that extends from 30 to 60 degrees latitude. According to the present defined types of Martian glaciers, this tongue is what scientists have dubbed a lobate debris apron, a glacier that in many ways resembles glaciers we see on Earth.
The location of this feature is especially interesting, especially because other images have found that it is not unique to this region.

Australia has committed $150 million to help its private sector contribute to NASA’s Artemis project and Trump’s goal to land a manned mission on the Moon by 2024, signing a joint agreement with NASA on September 21.
The government is investing $150 million over five years for Australian businesses and researchers to join NASAโs endeavour, and deliver key capabilities for the mission. โWeโre backing Australian businesses to the moon, and even Mars, and back,โ Prime Minister Scott Morrison said. โWeโre getting behind Australian businesses so they can take advantage of the pipeline of work NASA has committed to.”
The specifics, as quoted from the agreement, are somewhat vague.
This agreement is part of NASA’s effort to accumulate allies for both Artemis and its lunar space station Gateway. Australia has now joined Russia, Europe, Japan, and Canada. All of these nations and their space agencies desperately want the U.S. project to take place, most especially Gateway, as it will firm up funding for them all for decades.
NASA already has the big space contractors behind Artemis, though Boeing has expressed some opposition to Gateway. It has also awarded a lot of small contracts to a number of companies in the new commercial space industry to support Artemis. On top of this, it has distributed the project’s management within NASA so as to solidify support in Congress.
By accumulating these allies whose interests are in line with NASA’s goals, the agency hopes to convince Congress to fund the project. Unfortunately, the House, controlled by the Democrats whose only policy goal these days is to oppose Trump, have so far refused to fund the Trump 2024 manned mission.
Whether Artemis and Gateway will happen remains an open question. Congress wants the pork both projects will bring them. I predict that if both houses of Congress return to Republican control in 2020 they will fund this boondoggle.
Unfortunately, this won’t get us anywhere near the Moon, as the project as designed actually makes lunar landings more difficult and expensive. Getting from Gateway to the lunar surface requires more equipment and fuel than going directly there. If built as NASA has proposed, our astronauts will watch from Gateway as China and India land and begin settling the Moon.
But it will justify the spending of a lot of taxpayer money in congressional districts for decades to come. Hooray!
Capitalism in space: SpaceX’s offer to buy the last homes in the hamlet of Boca Chica for its Starship spaceport has been rejected by some of the landowners.
Their reasons are obvious. They don’t want to move, and they also claim the appraisals SpaceX used to set its price, which the company claims is three times the value of the homes, are too low.
Although the Hawthorne, Calif.-based rocket company, in a letter dated Sept. 12 and sent via FedEx, is offering the Heatons three times the appraised value of their home, they say the offer isnโt close to what theyโd need to sell. The appraisal conducted by SpaceX is several thousand dollars less than an appraisal the Heatons got through their bank five years ago, Terry said.
โI sent them an email the day after we got this letter, not being sarcastic or anything else,โ he said. โI just told them the facts, that (their) appraisal is extremely low.โ
If they obtained an appraisal five years ago that is less than SpaceX’s now, than SpaceX is certainly not offering them three times the value of their home.
SpaceX does not have the right to condemn these properties, as does the government. It must reach an equable deal with the landowners. In the case of the Heatons and several others, it sounds like this is going to take a lot of money. They want enough so that they can buy something comparable elsewhere.
China today used its Long March 3B rocket to launch two more GPS-type satellites in its Beidou constellation.
The leaders in the 2019 launch race:
17 China
14 Russia
10 SpaceX
6 Europe (Arianespace)
The U.S. continues to lead China in the national rankings 19 to 17, but China has been creeping up.
