Chang’e-5 on its way back to Earth

3:04 pm

The new colonial movement: Chang’e-5 today successfully fired four engines for 22 minutes to leave lunar orbit and begin its journey back to Earth, with a planned arrival date in China for its sample return capsule around December 15/16th.

The return capsule is expected to land in northern China in the Inner Mongolia region after separating from the rest of the spacecraft and floating down on parachutes. The material would be the first brought back since the Soviet Union’s Luna 24 probe in 1976.

The rocks and other debris were obtained both by drilling into the moon’s crust and scooping directly off the surface. They may be billions of years younger than those brought back by earlier U.S. and Soviet missions, possibly offering insights into the moon’s history and that of other bodies in the solar system.

The landing sequence is the last major engineering challenge, though hardly as challenging as the autonomous rendezvous and docking in lunar orbit.

SpaceX successfully launches commercial radio satellite

1:32 pm

Capitalism in space: SpaceX today successfully launched a new commercial radio satellite for Siruis.

The first stage was making its seventh flight, the fifth in 2020. It successfully landed on the drone ship. The fairings were also both previously flown.

The leaders in the 2020 launch race:

33 China
24 SpaceX
13 Russia
6 ULA
5 Rocket Lab
5 Europe (Arianespace)

The U.S. now leads China 38 to 33 in the national rankings. The U.S. has also completed the most launches in a single year since 1968. Unlike 1968, all the launches this year were flown by private companies, either for commercial customers or for the government, with rockets owned by the companies. In 1968 almost all the launches were for the government, and the rockets were controlled by the government, even if built by private companies.

Note that this very successful year occurred during a year when many businesses were forced to shutdown due to the Wuhan panic. It appears many rocket companies decided this was not a reason to cease operations.

Virgin Galactic’s first Unity launch from New Mexico fizzles

3:54 pm

Capitalism in space: Virgin Galactic’s first attempt to launch its SpaceShipTwo Unity suborbital spacecraft from its New Mexico spaceport ended almost immediately after the ship was released from WhiteKnightTwo when its engines did not ignite.

All appeared normal during the flight’s early phases. VSS Unity was carried into the air by its twin-fuselage mothership, known as WhiteKnightTwo VMS Eve, and was released to fly free at an altitude of more than 40,000 feet.

A webcast provided via NASASpaceflight.com showed the flash of the plane’s hybrid rocket motor lighting up, but only for a second. After the flame-out, Test pilots Dave Mackay and C.J. Sturckow brought Unity back down to the spaceport for a gliding landing.

I wish Virgin Galactic well, but at this point consider the company a backwater in the drive to develop a commercial space tourism industry. It took them too long to get to this point. Even if they should start flying tourists next year, they will be competing with orbital tourist flights by SpaceX, and the contrast is stark. I simply no longer see a viable customer base for Virgin Galactic, unless they get a lot of government subsidies.

Indonesia & SpaceX considering launchsite there

8:26 am

Capitalism in space: Indonesia has been in discussions with SpaceX and Elon Musk about establishing a SpaceX launch site in that country.

President Joko Widodo discussed the idea with SpaceX founder Elon Musk during a phone call on Friday, the Coordinating Ministry for Maritime and Investment Affairs said in the statement. Musk intends to send a team to Indonesia in January to study partnership opportunities, it said.

Makes sense for Musk to consider such a move, especially if the U.S. and Texas governments start to turn the screws on his Boca Chica launch site. Furthermore, it is his intention to eventually launch Starship/Super Heavy from a floating launch platform. Establishing arrangements with other foreign nations for putting it in their waters gives the company more flexibility.

People always migrate toward freedom. For two hundred and fifty years, that meant they moved to the United States. This now is changing, as the U.S. culture is signaling its increased hostility to this most important founding principle. Expect more stories like this in the coming decades.

Supreme Court dismisses Texas suit on election

7:04 pm

The dead Constitution

The Supreme Court today dismissed the Texas lawsuit asking it to invalid the election results in Pennsylvania, Michigan, Wisconsin, and Georgia because of election law changes made by bureaucrats rather than the state legislatures as directed by the Constitution.

The U.S. Supreme Court on Friday evening rejected the state of Texas’ challenge to the 2020 election results in four battleground states, extinguishing one of the last remaining hopes for President Trump’s campaign to reverse Joe Biden’s lead in those states.

“The State of Texas’s motion for leave to file a bill of complaint is denied for lack of standing under Article III of the Constitution,” the justices ruled. “Texas has not demonstrated a judicially cognizable interest in the manner in which another State conducts its elections. All other pending motions are dismissed as moot.”

No one should be surprised by this. It is not the court’s job to give permission to the state legislatures to do their job. It is their responsibility to act, and they have ample evidence that the vote has been, if not stolen, very unreliable and not trustworthy.

They are just too cowardly to do it. They’d rather have an excuse to cop out. They will now do so, saying that they can’t do anything because the Supreme Court told them they couldn’t. This is a lie, and a joke.

The election has been stolen. Do not expect there ever again to be a legitimate election in the United States. Expect Democrats to begin winning every race, in every battleground swing state.

New data confirms and localizes uplifted lunar dust as seen by Apollo astronauts

1:11 pm

The uncertainty of science: In a paper released today, scientists reveal the detection of electrostatic dust events on the Moon similar to those observed by Apollo astronauts, and find that these events might not be global but instead confined to craters during twilight. From the abstract:

Lunar horizon glows observed by the Apollo missions suggested a dense dust exosphere near the lunar terminator. But later missions failed to see such a high‐density dust exosphere. Why the Apollo missions could observe so large number of dust grains remains a mystery. For the first time, we report five dust enhancement events observed by the Lunar Dust Experiment on board Lunar Atmosphere and Dust Environment Explorer [LADEE] mission, which happen near a twilight crater with dust densities comparable to the Apollo measurements. Moreover, the dust densities are larger on the downstream side of the crater and favor a higher solar wind temperature, consistent with an electrostatic dust lofting from the negatively charged crater floor. We also check the Apollo observations and find similar twilight craters, suggesting that the so‐called dust exosphere is not a global phenomenon but just a local electrified dust fountain near twilight craters.

The dust clouds the astronauts thought they saw near the horizon have been theorized to be dust uplifted by static electricity. However, all later missions had so far failed to detect this phenomenon, until now. That the result also pinpoints the location and ties it to twilight is important for future missions to the Moon. Astronauts can thus minimize any damage by this dust by shutting down operations during lunar twilight periods.

Breaking: Starship prototype #9 tips over inside assembly building

12:43 pm

It appears from the 24-hour live stream provided by LabPadre that the ninth Starship prototype tipped over inside the assembly building to rest against one wall. You can see it happen at about 8 seconds into the video below:

No word on whether anyone was hurt, nor any information about the cause. My guess is that it occurred during the operations to move this prototype to the launchpad.

UPDATE: It appears no one was hurt, but there is damage to the fins, which might also mean damage to the hull. This in turn might make it unsafe to fly this prototype, as the hull forms the walls of the methane/oxygen tanks.

The day has not been good for SpaceX. Earlier they had to scrub the launch of a commercial communications satellite at T-30 seconds for reasons that they did not provide. High altitude winds had delayed the launch an hour or so, but it appears this was not the reason. According to SpaceX’s website, “SpaceX is standing down from Friday’s launch attempt of the SXM-7 mission to perform additional ground system checkouts.” They are targeting Sunday for the next launch attempt.

Strange crater in the basement of Mars

12:25 pm

Strange crater in Hellas Basin
Click for full image.

Today’s cool image to the right, cropped and reduced to post here, is intriguing for a number of reasons. Taken on September 11, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it shows a partially buried crater found in the middle of Hellas Basin, the lowest point on Mars and what I like to call the red planet’s basement.

What makes this crater intriguing is the layered pile of material filling its interior. If I didn’t know any better, I would think some construction crew has used a bulldozer to push debris from the crater’s right half in order to smooth the ground in preparation for building a strip mall, office building, or housing development.

This of course is not what happened. Then what did create those layered piles in the crater’s left half?

Boeing and NASA delay again the 2nd unmanned demo flight of Starliner

12:23 am

Boeing and NASA yesterday announced that they now plan to fly the second unmanned demo flight of Starliner in late March, rather in January as last scheduled.

Though there have been hints for awhile that a launch close to the start of the new year was no longer likely, this announcement confirms those hints. This means that it will have taken Boeing more than a year to fix the software issues that forced the first demo mission to abort its docking with ISS and come back early.

Whether this will delay the manned mission, which they are still targeting for as early as the summer of ’21, remains unclear. I think it will all depend on how well that the demo mission goes.

ULA’s Delta-4 Heavy successfully launches reconnaissance satellite

6:18 pm

Capitalism in space: After a several month delay, ULA’s Delta-4 Heavy tonight successfully launched a reconnaissance satellite for the National Reconnaissance Office.

The leaders in the 2020 launch race:

33 China
23 SpaceX
13 Russia
6 ULA
5 Rocket Lab
5 Europe (Arianespace)

The U.S. now leads China 37 to 33 in the national rankings. The U.S. launch total this year matches the number of launches achieved in 1969, and is the most launches by the U.S. in a single year since then.

Arizona state senate to hold official hearing tomorrow on election

3:23 pm

In a major shift, the Arizona state senate will tomorrow to hold an official hearing, with subpoena powers, on the questions relating to the vote count of the November 3rd election.

The hearing will be live streamed on the Arizona government’s website.

Whether it will be substantive, or designed to obscure the issues, remains unclear. The track record of the Republican leadership nationwide for the past two decades has consistently had them mouth platitudes in order to con their conservative base into thinking they were working in their interest, when in truth that leadership was repeatedly trying to do the exact opposite.

I hope I am wrong. It does appear that the many serious and substantive allegations relating to the vote are forcing the Republican leadership to respond, even if it is against their desire. Such an official Senate hearing would have to be called by the Senate president, Republican Karen Fann, which means it must have her endorsement.

Morocco agrees to Abraham accords, normalizing relations with Israel

2:23 pm

Today President Trump announced that Morocco has agreed to become the fourth Islamic/Arab nation to sign the Abraham Accords, thus establishing normal diplomatic relations with Israel.

America gave Morocco an important concession as part of the deal. “Today, I signed a proclamation recognizing Moroccan sovereignty over the Western Sahara,” Trump added. “Morocco’s serious, credible, and realistic autonomy proposal is the ONLY basis for a just and lasting solution for enduring peace and prosperity! Morocco recognized the United States in 1777. It is thus fitting we recognize their sovereignty over the Western Sahara.”

Whether these deals will survive a Biden administration remains unclear. What is clear is that unlike any administration since the Carter administration in the late 1970s, Trump has successfully achieved the first peace deals between Israel and its Arab neighbors. His approach, different than the accepted wisdoms of the Washington establishment, succeeded where those accepted wisdoms had failed.

It is a shame that the unmitigated and irrational hate that so many on the left have of Trump has made them incapable of recognizing this accomplishment. The nation, in fact the world, should be celebrating these deals with enthusiastic joy. It is not, for these childish reasons.

Video: How election officials can cheat with Dominion voting software

1:45 pm

The video is from today’s hearing in the Georgia legislature on the questions regarding the November 3rd election. Just watch. As noted at the link where I got the video:

Elections Supervisor Misty Martin gives a hands on demonstration of how to cheat with Dominion. This video was shown today by Colonel Waldren during his Georgia House of Representatives testimony.

The Dominion voting machines that Georgia and several other states use are open to manipulation during the counting process. This first of two videos shows the weaknesses of the system and the ways in which an unscrupulous election official may alter ballots with virtually no chance of being caught.

The point here is not whether anyone tampered with the results. The point is that the Dominion software used is utterly unreliable and can be used easily to tamper with the results. Any election that depended on this software is thus highly suspect, and should be thrown out.

It also means that if this software is used we cannot trust the results from the runoff of two Senate races in Georgia in January.

Watch ULA try again to launch its Delta-4 Heavy

9:09 am

Capitalism in space: ULA will today try once again, after numerous scrubbed and aborted attempts in August and September, to launch its Delta-4 Heavy rocket carrying a National Reconnaissance Office spy satellite.

The mission is set to take off at 6:15 p.m. EST (2315 GMT) Thursday from pad 37B at the newly-renamed Cape Canaveral Space Force Station in Florida. Forecasters predict near-ideal weather with a 90% chance of favorable conditions during the launch window Thursday evening.

Many of the launch problems earlier this year were due to issues in the launch pad. The article at the link describes the major refurbishing that ULA has done since then to fix them.

I have embedded their live stream of the launch, below the fold. It is set to go live at 5:55 pm (Eastern).

Note also that the next few days will be very busy for the American rocket industry. Tomorrow (Friday) both SpaceX and Astra have launches scheduled, with the latter making its second attempt to complete its first orbital launch. Then Rocket Lab has another Electron launch from New Zealand scheduled for the next day (Saturday).

That’s four launches in three days. If just two succeed, it will raise the total U.S. launches in 2020 to 38, which would be the most American launches in a single year since 1969, the year the country put men on the Moon.

Smallsat rocket startup Obex raises $24 million

8:52 am

Capitalism in space: The smallsat rocket startup Obex of the United Kingdom today announced that it has raised $24 million in private investment capital to support the development of its Prime rocket.

Conceived and developed as an environmentally sustainable launch system, the Orbex Prime rocket uniquely uses bio-propane, a renewable biofuel that cuts CO2 emissions by 90% compared to traditional kerosene-based rocket fuels. Designed to be recoverable and re-usable, Orbex Prime is intended to leave no debris in the ocean or in orbit around the Earth. The company is constructing the rocket vehicle at factories in Forres, near Inverness in Scotland, and Copenhagen in Denmark.

…Orbex has already confirmed six commercial satellite launch contracts, with the first launches expected in 2022. The company’s preferred launch site will be the Sutherland spaceport on the northernmost coast of Scotland, which was granted planning permission in mid-August 2020.

Whether the Sutherland spaceport happens however remains uncertain. Though it still appears to be moving forward, there is a lot of local opposition to it, some with clout. It appears however that Orbex is aware of this reality, and is developing Prime to allow it to launch from other sites.

That the company is trying to build this rocket as reusable right from the beginning is encouraging. It shows that the rocket industry is finally accepting the new paradigm established by SpaceX. For them to achieve this by ’22 however will be quite challenging.

Beresheet-2 will have two landers instead of one

8:42 am

The new colonial movement: SpaceIL, the Israeli non-profit company that built the failed Beresheet-1 lunar lander, yesterday announced its plans to build Beresheet-2, this time with an orbiter and two lunar landers, and launch it by ’24.

The two landers would be much smaller than the first spacecraft — about 260 pounds each, fully fueled, compared with a bit less than 1,300 pounds for Beresheet — and they would land on different parts of the moon. The orbiter would circle the moon for at least a couple of years. The three spacecraft of Beresheet 2 would together weigh about 1,400 pounds.

Even though the designs would be new, they would reuse many aspects of Beresheet, and the founders said they had learned lessons that would increase the chances of success for the second attempt. SpaceIL will again collaborate with Israel Aerospace Industries, a large satellite manufacturer.

SpaceIL is looking for funding from both private and Israeli government sources. It is also looking for funds from other nations, a decision which revealed the most intriguing part of this announcement:

SpaceIL hopes that international partnerships will pay for half of the cost of Beresheet 2. Mr. Damari said the United Arab Emirates, a small but wealthy country in the Persian Gulf that has set up an ambitious space program in recent years, was one of seven nations interested in taking part. He declined to name the other six.

If this flight ends up to be a partnership between Israel and the United Arab Emirates it will send shockwaves through the Arab world, most especially among the supporters of the terrorist leaders ruling the Palestinian territories.

China launches two science satellites with its Long March 11 rocket

8:23 am

The new colonial movement: China yesterday completed the eleventh successful launch of its Long March 11 rocket, putting two astronomy satellites in orbit designed to supplement gravitational wave research.

The satellites appear designed to look in other wavelengths at the region of sky from which gravitational waves are detected, and better pinpoint their location and nature.

This Long March 11 launch continues its perfect launch record. It uses solid rocket motors, derived from military missiles, which allow it to be stored easily and then launched quickly.

The leaders in the 2020 launch race:

33 China
23 SpaceX
13 Russia
5 ULA
5 Rocket Lab
5 Europe (Arianespace)

The U.S. still leads in the national rankings, 36 to 33, over China. And before anyone asks, yesterday’s SpaceX test suborbital flight of Starship does not qualify as a launch in these standings, as I only include successful orbital launches.

Key legal issues behind the Texas petition to Supreme Court re election issues

3:37 pm

Link here.

The author reviews the petition, the logic behind it, and the legal possibilities. She also cogently reviews the worst examples of misbehavior in the four swing states, Wisconsin, Pennsylvania, Georgia, and Michigan, that justify Supreme Court action. If you are one of those people that refuses to recognize the illegalities in the handling of the election in those states, you should read this article to education yourself.

The key point however is this:

These injuries, Texas asserts, demand a remedy. But the remedy sought is not what some may surmise is the goal—a second term for President Trump.

No, what Texas seeks is for the Supreme Court to mandate that the defendant states comply with the Constitution, and that means that electors are selected by the states’ legislatures. Texas makes this point clear, stressing: “Plaintiff State does not ask this Court to decide who won the election; they only ask that the Court enjoin the clear violations of the Electors Clause of the Constitution.”

Texas is essentially demanding what I suggested several weeks ago: If election issues are not fixed, elected state Republicans must refuse to certify.

Texas is demanding that these four states put the decision to the legislatures, since their election counts cannot be trusted. While the arguments are sound, it remains to be seen whether the Supreme Court will listen.

Watch the attempted first high altitude flight of SpaceX’s Starship

Starship on launch pad
Screen capture from SpaceX live feed during 1st launch attempt.
Click for LabPadre live stream,

UPDATE: Less than six minutes to launch.

UPDATE: Hold called at T-2:06. They have reset the clock for a 4:40 pm (Central) launch.

Original post:
——————-
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.”
