Momentus to go public

9:29 am

Capitalism in space: Momentus, an company focused on providing tugboat services in orbit, will become a publicly traded stock in conjunction with its merger with another investment company.

In recent months, Momentus has expanded its staff and business line to include hosting payloads and capturing satellites already in orbit with a robotic arm the firm is developing with Made In Space Europe, a Redwire subsidiary.

Through the merger and public offering, Momentus hopes to obtain capital to speed up development of its family of space tugs. In addition to Vigoride, Momentus is developing Ardoride, a vehicle to move small and medium-size satellites to custom orbits, and Fevoride, a vehicle to move “dozens of tons of cargo anywhere in outer space,” according to the Momentus website.

With this deal I think there will be two new space companies traded publicly, Momentus and Virgin Galactic. Unlike Virgin Galactic, whose stock is based on smoke and mirrors, Momentus is actually providing a commercial product that fills a need in space, and sounds like a good investment.

Starliner Commander steps down from first manned mission

9:19 am

Capitalism in space: Boeing’s company astronaut chosen to command the first manned mission of its Starliner capsule has stepped down because the flight would prevent him from attending his daughter’s wedding next year.

In a video posted to his Twitter account, Ferguson said it was a difficult decision, but “next year is very important for my family.” He said he has several commitments “which I simply cannot risk missing.” A Boeing spokeswoman confirmed one is his daughter’s wedding. “I’m not going anywhere. I’m just not going into space next year,” Ferguson said. He stressed that he remains committed to the Starliner program and will continue to work for Boeing.

This is the second crew change for this mission. Earlier NASA astronaut Eric Boe had had to back out due to medical reasons.

Assuming the second unmanned Starliner demo mission scheduled for the December-January timeframe succeeds, the first manned mission will happen in June ’21, and last anywhere from two weeks to six months.

Military considering using Starship for point-to-point transportaion

9:13 am

Capitalism in space: The U.S. military has begun a study in partnership with SpaceX on whether it will be possible to use Starship as a cargo ship for moving large shipments from point-to-point on the Earth.

Army Gen. Stephen Lyons, commander of U.S. Transportation Command, announced the agreement Oct. 7 at a National Defense Transportation Association virtual conference. “Think about moving the equivalent of a C-17 payload anywhere on the globe in less than an hour,” Lyons said. The C-17 is a very large military cargo plane capable of transporting a 70-ton main battle tank.

Makes sense. This decision also suggests the military is impressed with SpaceX’s progress on Starship, and has also largely abandoned its earlier skepticism of the company.

A typical mid-latitude Martian crater with glacial features

Typical mid-latitude Martian crater with glacial fill
Click for full image.

Cool image time! The crater on the right, the image cropped and reduced to post here, is a great example of many craters scientists have found in the mid-latitudes on Mars containing a variety of features that suggest buried glaciers. In this case we are looking at what they have dubbed a concentric crater fill, material that resembles glacial material that fills the crater’s interior and floor, and appears often to erode in a series of rings. You can see another example here.

The photo was taken on June 29, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The crater itself is located in a region of chaos terrain dubbed Nilosyrtis Mensae, located in the transition zone between the cratered southern highlands and the lowland northern plains.

Nilosyrtis Mensae is part of a region of Mars I call glacier country. When you include the mensae regions Protonilus and Deuteronilus to the west, this transition zone of random mesas, knobs, and criss-crossing canyons stretches about 2,000 miles. The context map below focuses in on Nilosyrtis Mensae, where this crater is located.

Government takes down pro-Trump sign on private property, without permission

10:46 am

They’re coming for you next: California state officials quickly moved to take down a pro-Trump billboard, even though it was on private property and they apparently did not have permission to do so.

This LA Times report on the massive Trump sign on a hill near the 405 says that state authorities went on private property to take it down because they claimed the political speech was a “visual distraction” to drivers.

So, in California your first, fourth, fifth, and sixth amendment rights are now null and void. If government officials don’t approve of your political signage, they now claim the right to enter your property, without permission and without a search warrant, and take down your signage.

The article at the first link notes that for some reason, these same California authorities did not consider it a “visual distraction” for Antifa and Black Lives Matter protests to stand on these same highways and block traffic.

Radio astronomers claim negative impact from satellite constellations

10:35 am

Put them on the Moon! Radio astronomers have released a paper claiming that the coming large communication satellite constellations, such as Starlink and OneWeb, will seriously impact observations with the Square Kilometer Array (SKA) of radio telescopes being built in the remote western outback of Australia.

Saturation of the instruments: very strong interfering signals can saturate the receiver systems and thereby drown out all other signals seen by the Band 5b receivers. As a consequence, all data in that frequency band would be lost, rendering these receivers useless for a portion of the time. For the first phase of the constellation deployments (about 6,400 satellites in total), saturation is predicted to occur for a few percent of the time assuming there is no direct illumination of the dishes by the satellites. For significantly larger constellation sizes (up to more than 100,000 satellites), saturation would be essentially continuous without significant mitigation measures implemented by the satellite operators.

Based on this conclusion, the astronomers estimate that for observations in this particular band they will need to look about 70% longer to get the same data, thereby cutting the number of observations by about half.

The astronomers propose this solution:

One of these mitigation techniques is for the satellite transmitters not to point their beams near the SKAO dishes. SKAO would require operators to steer their satellites’ beams away from the telescope site, a measure which would require a simple software modification with no repercussion on the constellation’s deployment, positioning or hardware. While a cost-effective implementation of this solution does depend on the hardware and software deployed on the satellites, operators already use this technique to comply with international regulations when their satellites cross the path between geostationary satellites in higher orbit and their receiving ground stations, for example to avoid affecting telecommunications and TV transmissions.

This mitigation could reduce the impact on the SKA by a factor of 10 over that noted previously and result in a 7% increase of integration time for SKA observations within the satellite transmission range 4. While any loss of sensitivity is regrettable, SKAO recognises the need for compromise between the competing scientific and commercial drivers.

The solution seems reasonable, but in truth it is only a temporary one. The permanent and smart solution for the astronomical community is to move their telescopes, in all wavelengths, off the Earth. For radio astronomy the far side of the Moon would be ideal.

And with SpaceX now developing a reusable big rocket, Starship, to put such payloads in orbit at low cost, the astronomers need to start thinking about taking advantage of this engineering. The situation for ground-based astronomer will only get worse.

China releases images of Tianwen-1 on way to Mars

10:12 pm

Tianwen-1 on its way to Mars

China has released several images taken of its Tianwen-1 orbiter/lander/rover by a camera ejected by the spacecraft on its way to Mars.

The images released by the China National Space Administration on Oct. 1 show the Tianwen 1 spacecraft traveling through the blackness of space. Tianwen deployed a small camera to take the self-portrait as it tumbled away from the mothership.

Two wide-angle lenses on the deployable camera were programmed to one image every second. The images were transmitted back to Tianwen via a wireless radio link, then downlinked back to ground teams in China.

In the images, Tianwen 1’s solar array wings and dish-shaped high-gain communications antenna are prominently visible. The white section of the spacecraft is the mission’s entry module and heat shield, which contains a Chinese rover designed to land on Mars and explore the surface.

The spacecraft is about halfway to Mars, and will arrive in Mars orbit in February. It will then spend several months surveying its candidate landing sites, of which there appear to be two, before releasing the lander/rover to the surface.

Trump orders release of all Spygate documents, with no redactions

8:56 pm

President Trump tonight ordered officials at the various agencies implicated in the Clinton/Russian collusion hoax and the illegal spying on his campaign by the Obama administration to release of all related documents, with no redactions, declassifying everything fully.

“I have fully authorized the total Declassification of any & all documents pertaining to the single greatest political CRIME in American History, the Russia Hoax. Likewise, the Hillary Clinton Email Scandal. No redactions!” Trump tweeted.

“All Russia Hoax Scandal information was Declassified by me long ago. Unfortunately for our Country, people have acted very slowly, especially since it is perhaps the biggest political crime in the history of our Country. Act!!!”

If this is so, then we are about the see the lid blow on this entire scandal, at last. These agencies have been hiding the facts by claiming that they need to redact a great deal of what is in any documents they are ordered to release. When those redactions however have been later stripped away so that we can read what was actually there, we have consistently found there was no justifiable national security reason for them. Instead, the only reasons for them was to to protect the lawbreakers at these agencies.

Since the leadership at these agencies is increasingly on Trump’s side in this matter, I suspect they will have no problem releasing everything, very quickly. I think we shall soon see clear evidence that former FBI head James Coomey and former CIA head John Brennan were directly involved in this spying operation, they made a conscious effort to manufacture a scandal for the express purpose of overthrowing the legally elected President of the United States, and they instigated it with the approval of the previous President, Barack Obama.

“When someone says he wants you dead, he wants you dead.”

1:17 pm

Link here. The author reviews the almost gleeful desire by many Democrats and their base to have Trump and his supporters die, either of COVID-19 or from a political revolution instigated by them.

And that’s a very dangerous thing to want, because the intended victim gets a say, and he may start saying the same thing about you. I could talk about walking through the wrecked villages of Kosovo – villages that had mostly belonged to the Serbs who started the civil war then lost it – but that is probably going to be lost on the pampered and parochial left. History, be it modern Balkans or ancient, such as the cautionary tale that was the decline and fall of the Roman Republic, is something they are too smart to bother studying. They know what they think and what they want and they can’t be bothered with pests nagging them about how their paucity of wisdom could very well set into motion events they cannot control and that are unlikely to turn out in the way they hope.

Read it all. He concludes by noting that we have a chance on election day to stop these fascist Democratic Party thugs, if only for another four years. And he is right. The defense of liberty never ends, and the moment you think so is the moment your liberty begins to disappear, taken by bullies whose only interest in life is the wielding of power.
