Peculiar flows on Mars
Click for full image.

Today’s cool image focuses on one of the weirdest flow features I have yet seen on Mars. The first photo to the right, rotated and cropped to post here, comes from a January 27, 2021 picture by the high resolution camera on Mars Reconnaissance Orbiter (MRO). This cropped section focuses on the middle of three such weird features, two close flows heading downhill on the interior rim of very eroded 28-mile-wide crater. For some reason the flows also have depressions on their crowns. The depressions almost look like someone carved them out with a spackling spatula. In fact, the MRO science team agrees, labeling this image as “Spatulate Depressions with and without Upslope Gullies.”

The second image to the right shows a wider crop of the same picture, and explains the reason for the last half of that label.

Ingenuity unfolded and ready for placement on ground

9:59 am

Ingenuity unfolded
Click for full image.

The photo to the right, taken yesterday, shows Perseverance’s Ingenuity helicopter now vertical with its legs deployed, hanging from the bottom of the rover and ready for placement on the ground.

The next step will be drop Ingenuity those last few inches. Once released Perseverance will quickly drive away, as it will no longer be providing power to the helicopter and will instead be blocking its solar panels from sunlight.

Perseverance will then proceed to its lookout post while engineers check out Ingenuity to make sure all is working.

The targeted flight date remains April 8th.

UPDATE: JPL just announced that it is delaying Ingenuity’s flight to April 11th. The announcement was done by a tweet, so provided no explanation as to why JPL decided to delay three days.

Sierra Nevada will build space stations and a manned version of Dream Chaser

Sierra Nevada's proposed LIFE space station

Capitalism in space: Sierra Nevada announced today that it will not only build a manned version of its Dream Chaser reusable mini-shuttle, it now intends to use that shuttle as a ferry to its own space station, made up of inflatable modules.

They have dubbed their proposed station LIFE, and describe as follows:

The LIFE habitat is a three story, 27-foot large inflatable fabric environment that launches on a conventional rocket and inflates on-orbit. The LIFE habitat is undergoing a NASA soft-goods certification this year and the full size ground prototype developed under NASA’s NextSTEP-2 contract is in the process of being transferred from Johnson Space Center in Texas to Kennedy Space Center in Florida for further testing on short-and long-term habitation. SNC’s Astro Garden® system also provides fresh food within the habitat.

Making a manned version of Dream Chaser was always expected. Adding the company’s own station makes complete sense. Except for the rocket to launch a Dream Chaser spacecraft, Sierra Nevada will be able to provide a full service experience to, in, and from space.

Shetland spaceport application rejected by local monument authority

9:36 am

The application to build a spaceport on one of the Shetland Islands has been rejected by a local monument authority because it would cause “extensive and adverse impact on the cultural significance” of a WWII radar station.

Mr Strang [head of the spaceport organization] said he was “greatly surprised” by the decision, claiming HES [Historic Environment Scotland] had “done nothing to preserve the site for the last 50 years”.

Skaw is the UK’s most northerly Second World War radar station and protected as a scheduled monument of national importance. The proposed space centre would be built almost entirely with in the RAF radar station site. It would require the removal of nine buildings, including air raid shelters, guard huts and those associated with the radar system. More than 200 archaeological features, such as foundations of buildings, gun emplacements and bomb craters would also be removed.

The Shetland Islands are very remote with few job opportunities for its residences. Putting a spaceport there seems like an excellent idea, especially because it will create hundreds of jobs where none exist now.

The radar facility did the same, but it did so more than seventy years ago, during World War II. Protecting these old and unused buildings for the sake of those long gone jobs seems utterly foolish.

The spaceport people say they will oppose this decision, but it is not clear from the article what they can do. The law as written appears to give this historical agency full power to veto.

Industry group representing big tech demands Starlink be blocked in India

9:08 am

They’re coming for you next: An industry group representing a number of big tech companies like Amazon and Google has written India’s governmental agencies that regulate broadband and space and demanded that they block SpaceX’s Starlink internet service in India.

An industry body representing the likes of Amazon, Hughes, Google, Microsoft and Facebook has written to the Telecom Regulatory Authority of India (Trai) and the Indian Space Research Organisation (Isro) asking them to stop SpaceX from pre-selling the beta version of its Starlink satellite internet services in India. It claimed SpaceX didn’t have licence or authorisation from the government to offer such services in the country. “We request you to urgently intervene to protect fair competition and adherence to existing policy and regulatory norms,” Broadband India Forum president TV Ramachandran said in the letters, seen by ET.

I could have filed this story under my series, “Today’s Blacklisted Americans”. These big tech companies have made it very clear in numerous earlier stories that they do not believe in competition or free speech. They are now demonstrating it again in India. Both Amazon and Hughes are direct competitors with Starlink. Neither also has a product that can compete with it (Amazon appears years from deploying its system and Hughes’ system has latency issues that make it much slower than Starlink). So, they team up with their leftist buddies Google, Microsoft, and Facebook to demand the Indian government do their dirty work for them, shutting down their competition.

It is unlikely that India’s Modi government, which is very much in favor of private enterprise, will do what these thugs want, but you never know. Politicians are like whores, they do what you pay them. If India does move to block SpaceX however I also expect there to be an outcry in that country, as it has many rural areas that can only be served by the kind of service Starlink is offering.

Today’s blacklisted American: Former President Donald Trump

11:53 am

The cancelled Bill of Rights
What Facebook & Instagram want cancelled.

They’re coming for you next: Both Facebook and Instagram instantly removed today an interview of former President Donald Trump in which he suggested he might run again for president in 2024, merely because the clip contained his voice.

[The interview] was for The Right View. … During the 18-minute interview, Trump also spoke about running for President again in 2024. Lara [Trump, whose show it was and who is Trump’s daughter-in-law] had been promoting it on Facebook, Instagram and Twitter beforehand.

At 9.26pm on Tuesday night, four minutes before it was due to be uploaded, Facebook emailed Lara’s team warning them that it would be removed if it went live. At 9.51pm, they emailed again to say that they’d taken it down.

Lara shared screenshots of the emails on Instagram afterwards. ‘And just like that, we are one step closer to Orwell’s 1984. Wow,’ she wrote alongside them.

Trump has been banned from Twitter, Facebook and Instagram since the January 6 riots, cut off from his supporters and unable to get messages to them in the way he did before.

In their email, the Facebook employee said that ‘content posted in the voice of President Trump is not currently allowed on our platforms (including new posts with President Trump speaking) and will be removed. ‘This guidance applies to all campaign accounts and Pages, including Team Trump, other campaign messaging vehicles on our platforms and former surrogates’. [emphasis mine]

The audacity of this censorship of a former president of the United States by these companies is breath-taking. The highlighted quote makes it clear: Their goal is to silence Trump, in every way possible. They do not celebrate free speech, or the ability of everyone to express themselves publicly. The only people who will be allowed freedom of speech will be those who agree with them.

Though they are private companies who should have the freedom to publish who they wish, these companies also have been granted special tax status as utilities which provide a platform for everyone, not a publisher who picks and chooses what he wishes to publish. Under this tax benefit, they have no right to block anyone’s show, period.

Putting aside these legalities, why would any Republican, conservative, or anyone who supports free speech remain a user of Facebook, Instagram, or Twitter? They are not only clearly Democratic Party operatives, working to promote that political party’s agenda, they also clearly view anyone who disagrees with that agenda to be pond scum. Why provide any support to such authoritarians?

Ice under Mars’ biggest volcanic ash field, at the equator?

11:24 am

Wind eddies on Mars
Click for full image.

According to new data obtained from the radar instruments on Mars Reconnaissance Orbiter (MRO) and Mars Express, scientists now think that the Medusae Fossae Formation, Mars’ biggest volcanic ash field and thought by some to be the source of most of the planet’s dust, might have an underground layer of ash that is also ice-rich. From their abstract:

The Medusae Fossae Formation (MFF) on Mars covers a vast area along the boundary between the rugged southern highlands and the smooth northern plains. While the MFF appears to be thick sediments or volcanic ash slowly eroding in the martian winds, how this material was emplaced remains mysterious. Most intriguing is evidence suggesting that some areas of the MFF may contain water ice. In this work we use sounding radar data from the SHARAD instrument on the Mars Reconnaissance Orbiter to probe up to 600 m below the surface and measure the electrical properties of the MFF material. The results suggest that the shallow parts of the MFF deposits are very porous and compress readily under their own weight. To match deeper probing by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument on Mars Express requires a second layer of either vast porous deposits or ice‐rich material protected from sublimation by the dry sediments.

The MRO image above, originally posted here in November 2020, shows one example of the typical wind erosion found in the Medusae ash field. Apparently the ground-penetrating radar from orbit now suggests the possibility that there is an ash layer rich in ice, at depths beginning somewhere between 1,000 to 2,000 feet below the surface.

X-rays from Uranus detected for the 1st time

10:02 am

Composite Uranus image of X-ray and optical data

Astronomers using the Chandra X-ray Observatory in orbit have for the first time detected X-rays coming from the planet Uranus.

In the new study, researchers used Chandra observations taken in Uranus in 2002 and then again in 2017. They saw a clear detection of X-rays from the first observation, just analyzed recently, and a possible flare of X-rays in those obtained fifteen years later. The main graphic [posted to the right] shows a Chandra X-ray image of Uranus from 2002 (in pink) superimposed on an optical image from the Keck-I Telescope obtained in a separate study in 2004. The latter shows the planet at approximately the same orientation as it was during the 2002 Chandra observations.

What could cause Uranus to emit X-rays? The answer: mainly the Sun. Astronomers have observed that both Jupiter and Saturn scatter X-ray light given off by the Sun, similar to how Earth’s atmosphere scatters the Sun’s light. While the authors of the new Uranus study initially expected that most of the X-rays detected would also be from scattering, there are tantalizing hints that at least one other source of X-rays is present.

One explanation could be that the X-rays could be coming from Uranus’s rings, as such X-rays do from Saturn. This is not confirmed as yet however. More data will be needed.

FAA says it will “lead” investigation into Starship #11 crash yesterday

9:44 am

They’re coming for you next: The Federal Aviation Administration (FAA) announced today that it will “oversee” the investigation into the crash at landing yesterday by SpaceX’s eleventh Starship prototype.

The Federal Aviation Administration, which had an inspector at SpaceX’s facilities to observe the test flight, said in a statement that the FAA will oversee the company’s investigation into the “prototype mishap.” The FAA has conducted similar mishap investigations after previous Starship test flights. “The [Starship] vehicle experienced an anomaly during the landing phase of the flight resulting in loss of the vehicle,” an FAA spokesperson said. “The FAA will approve the final mishap investigation report and any corrective actions SpaceX must take before return to flight is authorized.”

The FAA noted that it will also work with SpaceX to identify reports of light debris in the area, saying that there have yet to be any reported injuries or damaged to public property.

What will really go on here is that an FAA official will observe closely as SpaceX conducts the investigation. That official might have some background in space engineering, but he or she will be completely unprepared to actually lead the investigation. Thus in the end the FAA will really only be able to rubber stamp SpaceX’s conclusions, though it might as all governments do, demand its own pound of flesh before issuing that stamp.

Up to now the FAA has tried very hard to work with the new commercial space companies, especially SpaceX, doing as little as it can to impede their progress. There are strong signs however that this might now change with the Democrats in control of the White House and Congress. If so, expect the FAA to cause SpaceX some grief during this investigation, grief that could significantly delay further test flights.

Three new German smallsat startup rocket companies vying for market share

9:32 am

Capitalism in space: Three new German startup companies have joined the race to grab a share in the burgeoning new cubesat/nanosat launch business, with each building their own new rockets.

The companies are dubbed Isar Aerospace, Rocket Factory, and HyImpulse..

Each is developing rockets capable of carrying between 500 and 1,500 kilos (3,300 pounds) into low Earth orbit. While that’s a fraction of the tens of thousands of kilos hauled by the Falcon 9, operated by Elon Musk’s Space Exploration Technologies Corp., it’s enough to transport the satellites now being deployed for everything from super-fast Internet to autonomous driving.

Isar plans its first launch in ’22, HyImpulse in ’23. The target date of Rocket Factory’s first launch was not revealed.

These European companies join dozens such new smallsat rocket companies that already exist. Which will survive the shake-out that always occurs in such new industries only time will tell.

Last two passengers on 1st entirely private manned spaceflight revealed

9:17 am

Capitalism in space: The last two passengers for the first entirely private commercial manned spaceflight, dubbed Inspiration4 and paid for by businessman Jared Isaacman, were announced yesterday, along with a launch date no earlier than September 15, 2021.

Isaacman bought the mission partly to fly in space, but also to raise money for St. Judes Children’s Research Hospital. Both Isaacman and Haley Arceneaux, a former St. Judes cancer patient, will fly. Their two new crew members are both experienced in aviation or spaceflight operations, though neither is a professional astronaut with any training in that field.

[Sian] Proctor describes herself as a scientist turned artist and an “analog astronaut” where people live in environments to simulate long-duration spaceflight. She has done four analog missions including NASA’s Hawai’i Space Exploration Analog and Simulation (HI-SEAS) Habitat to simulate a trip to Mars. She is a pilot, scuba diver, “and loves geoexploring our world.” Born in Guam while her father was working at a NASA tracking station there during the Apollo program, she has a B.S. in environmental science, an M.S. in geology, and a Ph.D. in Curriculum and Instruction: Science Education. She was a finalist in NASA’s 2009 astronaut selection.

While a U.S. Space Camp counselor, [Chris] Sembroski conducted simulated space shuttle missions and supported STEM-based education. He served in the Air Force maintaining a fleet of Minuteman III ICBMs and served in Iraq. After leaving the Air Force in 2007, he earned a B.S. in Professional Aeronautics from Embry-Riddle Aeronautical University. He now works for the aerospace industry in Seattle, although he did not specify what company.

Their spacecraft will be Resilience, the Dragon capsule that flew the first operational manned commercial crew to ISS, and is presently docked to the station. For the Inspiration4 flight however SpaceX is going to install a large domed window at the capsule’s nose, replacing the docking port that will not be needed.
