Capitalism in space: SpaceX’s live stream is on, with a liftoff in six minutes. I have embedded below the fold the live stream for this first high altitude flight of SpaceX’s Starship.

The LabPadre live stream, to the right, shows that they have already proceeded through most of preliminary stages prior to liftoff.

If all goes right, this eighth prototype of Starship will go about 40,000 feet in the air, turn over and attempt to control its return belly side down, and then upright itself just before landing so it can complete a vertical landing like a Falcon 9 first stage. The company gives themselves a one in three chance of landing the spacecraft. SpaceX has also made it clear that their primary engineering goal on this flight is to test that return through the atmosphere, so that is the part of the flight they most need to succeed. Failing to land afterward but getting that data will make this test a complete success.

No matter what happens, the company has prototypes 9 through 15 waiting in the wings.

UPDATE: This post will remain at the top of the page until the flight occurs, or is scrubbed. Scroll down for new stories.

Cryptic Terrain on Mars

1:01 pm

Cryptic terrain near Mars' south polar ice cap
Click for full image.

Cool image time! The photo to the right, rotated and cropped to post here, was taken on September 27, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what is likely a crater that is partly buried by ice and dust and sand near or on the edge of Mars’s south polar ice cap.

It also shows an example of what planetary scientists have dubbed “cryptic terrain,” found generally on the margins of that ice cap. In this case, the location is on a plateau adjacent to the ice cap dubbed Promethei Planum. Despite a lot of searching, I could not locate any research papers describing Promethei Planum, though data outlined in one Mars Express press release from 2008 suggested it was part of the polar ice cap more than two miles thick that is covered by a thin mantle of dry ice each winter.

The strange curlicue cliffs and plateaus seen here are thought to form as part of the arrival and then sublimation away of that seasonal dry ice mantle, but how that process exactly works to create these particular geological features remains I think a mystery. North is to the top. The general grade is also downhill away from the icecap to the north.

Moreover, the overview map below, with the location of this image indicated by the blue cross, illustrates more mysteries.

ESA funds construction of its own X-37B, dubbed Space Rider

11:23 am

The new colonial movement: The European Space Agency (ESA) has now signed the contracts to fund the construction of its first reusable mini-shuttle, dubbed Space Rider and comparable to the Air Force’s X-37B.

ESA signed two contracts with industry on 9 December at Palazzo Chigi in Rome, Italy in the presence of Italian government representatives. The first contract is for delivery of the Space Rider flight model including the reentry module and the AVUM orbital service module, by co-prime contractors: Thales Alenia Space Italy and Avio. The second contract covers the delivery of the ground segment by Italian co-prime contractors: Telespazio and Altec.

Activities are on track for the first flight of Space Rider in the third quarter of 2023 from Europe’s Spaceport in French Guiana.

Like the X-37B, Space Rider will provide Europe with a space platform for performing long term experiments in space and recovering them undamaged, though initially the flights will be no more than two months long. While it will launch on a rocket like the X-37B, and will use its body to shed velocity as it returns through the atmosphere, it will not land on a runway but will instead use parachutes to drop it to the ground.

More importantly, Space Rider will be available to the private sector. The X-37B is controlled by the U.S. military, and they have made it available for only a limited number of non-military experiments.

German smallsat startup raises $91 million for new rocket

9:36 am

Capitalism in space: A German startup, dubbed Isar Aerospace, has successfully raised $91 million in private investment capital to finance design and construction of a new rocket aimed at launching smallsats.

It plans to use the money to continue its research, development and production en route to its first commercial launches, planned for early 2022. The launcher is not just significant for its design innovation, but if it proves successful, it would make Isar the first European space company to build a successful satellite launcher to compete in the global satellite market.

The round, a Series B, is being led by Lakestar, with significant contributions also from Earlybird and Vsquared Ventures; additional funding from existing investors like Airbus Ventures, former SpaceX Vice President Bulent Altan, Christian Angermayer’s Apeiron, and UVC; and also new investors HV Capital and Ann-Kristin and Paul Achleitner are also joining the round.

Earlybird and Airbus Ventures led Isar’s previous round of $17 million in December 2019.

There are a lot of such startups right now, the majority of which I expect to fall by the wayside, especially the latecomers. What makes this particular story interesting is that it describes a European company. So far there has not been much activity in the new launch market coming from independent European companies. With the government-run Arianespace dominating the market, it is difficult for private companies to gain a foothold.

This might be changing because of the failure of Arianespace’s Ariane 6 to successfully compete on price with SpaceX, a failure that gives new companies an opening to gain some market share in Europe. The two recent launch failures of Arianespace’s smaller Vega rocket likely helps that new competition as well. Isar’s funding success here might be indicating this.

Starlink dark coating reduces reflectivity by half

9:23 am

Astronomers in Japan have now confirmed that the dark coating SpaceX has been putting on its more recent Starlink satellites has successfully reduced their reflectivity by half.

They looked at the satellites across a range of wavelengths.

Observations conducted from April to June 2020 revealed for the first time in the world that artificial satellites, whether coated or not, are more visible at longer wavelengths, and that the black coating can halve the level of surface reflectivity of satellites. Such surface treatment is expected to reduce the negative impacts on astronomical observations.

Knowing this detail will allow commercial satellite companies such as SpaceX to further refine their coatings to better hide their satellites from ground-based telescopes.

While good news, it doesn’t change the fundamental lesson that astronomers need to learn. They must move their telescopes off the Earth and into space. In the long run ground-based astronomy is a dead-end.

Musk confirms he has left California for Texas

11:43 pm

SpaceX founder Elon Musk today confirmed that he is selling his homes in California and is moving permanently to Texas.

Musk did not reveal whereabouts in the Lone Star State he has moved to. It’s also unclear whether he will purchase any property there, given that he stated earlier this year that he wants to rid himself of possessions and is only interesting in renting.

Over the summer, the Musk Foundation officially consolidated its headquarters in Austin – a city that also houses a Tesla assembly plant. However, Musk is also known to spend time in Boca Chica, on the southeast coast of the state, where there is a SpaceX facility.

For the time being, both Tesla and SpaceX remain headquartered in California. It is unclear whether Musk will officially move both businesses to Texas at a later date.

I expect that both Tesla and SpaceX in California will soon be leaving as well. Musk is shrewd however. He has been shifting both slowly from California in the past two years as he has found it increasingly impossible to deal with government officials there. Witness Starship for example. Two years ago it was to be built in the Port of Los Angeles. Now, with little fanfare all operations have moved to Texas.

Musk will leave slowly, so as to not stir a political hornet’s nest among the fascist legislators of California. They consider everything everyone owns as belonging really to them, and will not take kindly to any attempt of Musk to escape.

1st countdown dress rehearsal of SLS core stage scrubbed

4:34 pm

The attempt by NASA to conduct a full countdown dress rehearsal of the SLS core stage, including loading its tanks, was scrubbed early in the countdown yesterday when engineers encountered problems loading oxygen into the rocket’s tanks.

An issue with the LOX chilldown process run on Monday meant that the LOX propellant tank couldn’t be filled, which meant that the full WDR test wasn’t possible.

NASA’s post-scrub statement indicated the vehicle systems performed well and that the Core Stage engineering community and the test team at Stennis were working on fixes and determining when the tanking and countdown demonstration parts of the WDR test can be retried.

This dress rehearsal is intended to preparatory to what NASA dubs the Green Run test static fire of the core stage, set to last for the full 500 seconds the core stage would fire during an actual launch. Whether this scrub will prevent that Green Run test from occurring before the end of the year remains unclear. Either way it must happen soon if NASA is to maintain its schedule for the long frequently delayed launch of SLS, now scheduled for November ’21.

Launch abort for Starship high altitude flight

4:03 pm

Starship at T-1 second on launch pad
Screen capture from SpaceX live feed at T-1 second.
Click for LabPadre live stream.

The attempt today by SpaceX to fly its eighth prototype of Starship to 40,000 feet aborted at T-1 second, apparently because the rocket’s computers sensed something wrong and shut things down.

They have stood down for the day. At the moment there is no word on when they will try again, though they have a back up launch window for tomorrow, and SpaceX’s policy generally is to move forward quickly. The decision will likely depend on the reasons for the abort. I will bet they will try again tomorrow.

I have revised the the live feed post, removing references to today’s launch abort, since this information is now contained in this post. The live feed post however will remain at the top of the page.

Update on audit of Dominion tabulators in Michigan county

2:18 pm

Link here. Because of a lawsuit by a local citizen of Antrim County in Michigan, challenging the results of the vote count there, the court had granted that citizen access to the Dominion tabulator machines to obtain their data and do a full audit of the manner in which those machines counted the vote.

The article describes the effort to get that data, including the failed attempt by one local official to delay or block it. To protect the machines, citizens volunteered to stand guard for an entire weekend to make sure they were not tampered with before the lawyers and their software experts could access them.

The result?

After 8 hours, the collection was complete. With 16 CF cards (similar to SIM cards), 16 thumb drives, and forensic images of the Dominion voting machines in hand, the IT team was escorted to the local Antrim County Airport by two Antrim County Sheriff vehicles, where they boarded their jet plane with evidence in hand.

Two of the patriots followed attorney Matthew DePerno for at least half of his long drive home. Like many Americans, these patriots simply wanted to ensure the safety of a man who has risked so much to protect our right to free and fair elections.

Mr. DePerno expects to have the results of the study sometime tomorrow. He explained the forensic images of the thumb drives and the master computer would tell if machines were connected to the internet—and if they were, who were they communicating with? DePerno said the examination would be able to determine the algorithms used by the computer and will provide the number of ballots read through the machine compared to the actual number of paper ballots.

Every American should be demanding this be done with every computer tabulator nationwide, if only to reassure Americans that the vote was not faked by computer trickery.

That an unelected county official resisted such an audit however is very suspicious and indicates his incompetency. Regardless of how the audit comes out, this man, Peter Garwood, should be removed from office immediately. He does not appear to be properly representing the citizens. If he was, he would have gladly cooperated.

Landslides on the edge of Mars’ youngest lava field

Landslides on the edge of Mars' youngest lava field
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on September 28, 2020. It shows several indentations in a north-south cliff face, with debris apparently falling down into a flat plain to the east.

The scientific history of this picture is very interesting. The first photo of these landslides was taken in 2006 and was titled, “Landslides on Flat Topography in Elysium Planitia”. The second, taken a few months later in 2007 to produce a stereoscopic view, was labeled “Landslides Along Shoreline in Elysium Planitia.” This most recent 2020 image is merely labeled “Landslides in Elysium Planitia.”

Is the flat terrain to the west a seabed to an ancient ocean, as suggested by the title for the 2007 image, with these landslides erosion caused in the far past by water lapping up against these cliffs?

About 300K excess deaths in 2020 based on untrustworthy CDC data

9:34 am

Two different analyses today took a closer look at the Johns Hopkins report last week that claimed there were no excess deaths in 2020, despite the COVID-19 epidemic.

Though I remain unconvinced that the Wuhan virus is the plague that the fear-mongers keep claiming, the first story makes a good argument, using CDC statistics, that there have been excess deaths in 2020, though this same analysis makes no claim as to the cause of those excess deaths. The conclusion:

SpaceX’s Starlink constellation wins $885 million in federal subsidies

8:44 am

Capitalism in space: In awarding $9.2 billion in subsidies to providers of rural high-speed internet to rural customers, the FCC gave $885 million of this allocation to SpaceX’s Starlink constellation.

SpaceX was not the biggest beneficiary, however.

Most of the RDOF Phase I subsidies are going to terrestrial broadband service providers, led by LTD Broadband with an award of $1.32 billion. CCO Holdings, a subsidiary of Charter Communications, is due to serve 1.05 million sites around the country, leading the list for that metric.

The FCC said 85% of the 5.2 million sites to be served would get gigabit-speed broadband. SpaceX is due to serve nearly 643,000 sites with download speeds of 100 megabits per second or more.

Regardless of its good intentions, this distribution of federal cash sickens me. These companies don’t need it to do what they are doing, and are all sure to make plenty of profit without it. The federal government meanwhile is trillions in debt. It has to print money to give this away, something that is not going to go well in the long run.
