Pentagon getting serious of hauling cargo with Starship

June 2, 2021 9:13 am Robert Zimmerman

Capitalism in space: In the budget proposal submitted by the Biden administration the Pentagon included a request for $47.9 million to help develop the infrastructure it will need to use SpaceX’s Starship rocket as a method for transporting cargo point-to-point on Earth.

“The Department of the Air Force seeks to leverage the current multi-billion dollar commercial investment to develop the largest rockets ever, and with full reusability to develop and test the capability to leverage a commercial rocket to deliver AF cargo anywhere on the Earth in less than one hour, with a 100-ton capacity,” the document states.

Although this does not refer to Starship by name, this is the only vehicle under development in the world with this kind of capability. The Air Force does not intend to invest directly into the vehicle’s development, the document says. However, it proposes to fund science and technology needed to interface with the Starship vehicle so that the Air Force might leverage its capabilities.

Clearly, some Air Force officials are intrigued by the possibility of launching 100 tons of cargo from the United States and having the ability to land it anywhere in the world about an hour later.

The proposal is calling for a fourfold increase in funding for this work, as the Air Force is already spending slightly less than $10 million this year on this work.

The bottom line is that it appears SpaceX already has at least one real customer for its giant rocket. And if the military is that interested now, it likely means many more private customers are beginning to line up.

Tiny object hits robot arm on ISS

June 2, 2021 9:05 am Robert Zimmerman

According to the Canadian Space Agency, a very small piece of space debris hit that country’s robot arm on ISS at some point in the recent past, producing a hole about 5mm wide, or about 1/5th of an inch in diameter.

During a routine inspection on May 12 robotic operators observed the hole in the boom section of the Canadarm2. After working with NASA to take detailed images of the impact, the agencies concluded the hole is about 5mm in diameter.

The damage is limited to a small section of the arm boom and thermal blanket. CSA says despite the impact, the arm’s performance is unaffected.

While space junk is a concern, this story is not about that, even if the authorities at CSA are hyping it, and as usual the mainstream press (as indicated by the article at the link) is buying into the propaganda. Space stations like ISS and Mir are routinely hit by micrometeorites. Though most impacts are much much smaller than the object that produced this hole and do no significant harm, hits like this one have happened in the past.

However, almost all such impacts are from natural objects from space. In fact, as far as I know, tiny holes this size are always caused by natural objects (with the one exception of the hole someone in Russia accidently drilled into the hull of one Soyuz spacecraft). Yet, the officials at Canada’s space agency immediately used the discovery to lobby for action against human-made space junk, even though they also admit they have no evidence this hole was produced by space junk, and past evidence strongly suggests it was not junk.

The real story here is whether the hulls on ISS’s various modules are sufficiently robust to withstand such somewhat expected and not-so-unusual natural impacts. And based on the station’s survival without any issue now for almost a quarter century, it appears that its shielding is sufficient, and will likely work for any long term mission to Mars or beyond. In fact, that the impact did no significant harm to the robot arm, which has been operating without stop, is further proof of that good design.

This is not to say that natural objects aren’t a threat. The data just shows that the threat from really dangerous objects large enough to do real harm is very very rare, to the point that, from a cost-benefit perspective, it makes little sense to protect against them. Future interplanetary space stations can rely on the hull shielding designs now used with some confidence.

As for space junk, that certainly is a problem that must be addressed. It just isn’t what this story is really about.

Today’s blacklisted American: Supreme Court Justice Clarence Thomas

June 1, 2021 12:10 pm Robert Zimmerman

Clarence Thomas: Banned at amazon
Supreme Court Justice Clarence Thomas:
Blackballed by Amazon Prime.

Blacklists are back and Amazon’s got ’em: During Black History month in February, Amazon decided it would no longer live stream on Amazon Prime the documentary on the life of Supreme Court justice Clarence Thomas, Created Equal: Clarence Thomas in His Own Words.

In the midst of Black History Month, Amazon pulled a critically acclaimed and popular documentary on conservative Justice Clarence Thomas, the only black justice currently serving on the Supreme Court, from its streaming platform. The documentary, “Created Equal: Clarence Thomas in His Own Words,” is “currently unavailable to watch in your location,” the website reads when the title is clicked. The outage appears to be nationwide, as reported by Breitbart.

Amazon appeared to drop the PBS documentary, while still promoting a wide range of films including “All In: The Fight for Democracy” with Stacey Abrams and two movies on widely discredited activist Anita Hill.

That was in February, a time period when Americans of all stripes are supposed to celebrate the achievements of all blacks, no matter their politics. Amazon however for reasons that remain unexplained removed the Thomas documentary at that very moment, and has not reinstated it to this day. You can buy the dvd at Amazon, but you cannot watch it on Amazon’s live streaming service, even though the film’s maker, Michael Pack, was never offered an explanation for its removal.

SpaceX barrelling like a juggernaut toward first Starship/Superheavy orbital flight this year

June 1, 2021 9:36 am Robert Zimmerman

Starship #15 about to land
Starship prototype #15 about to land, May 5, 2021

A series of articles at Teslarati in the past two days suggest strongly that the next Starship flight will be on top of a Superheavy first stage, and will likely be the first near orbital flight from Texas around the globe to splashdown softly in the Pacific Ocean northeast of Hawaii.

And it will likely happen this year!

First there was the report from locals in the McGregor, Texas, area indicating that SpaceX has completed a full duration launch burn of a Raptor engine.

A local resident and unofficial SpaceX observer has reported hearing a test of one of Starship’s Raptor engines that lasted more than five minutes at the company’s McGregor, Texas development facilities.

If accurate, it could be the longest static fire of a Starship engine that SpaceX has ever completed in the two years since full-scale Raptor testing first began. Whether it was successful or not, a five or six-minute static fire would also confirm that SpaceX is well into the process of qualifying Raptor for Starship’s first orbital launch attempts.

This burn is somewhat longer than the engine burns during the Starship test hops, and approaches the burn time required for Superheavy during a launch.

Next there was the report describing the newest known engine configurations SpaceX is planning for Superheavy itself, with the first version possibly having 29 engines and a future more powerful version sporting 32.

New Zealand signs Artemis Accords

June 1, 2021 8:47 am Robert Zimmerman

On May 31st New Zealand became the 11th country to sign the Artemis Accords, designed to bypass the Outer Space Treaty’s limitations on property rights in space.

The full list, according to the NASA press release, now includes Australia, Canada, Italy, Japan, Luxembourg, South Korea, the United Kingdom, the United Arab Emirates, Ukraine, and the United States.

China and Russia have both said they oppose the accords. That such European nations as Germany and France have not joined in suggests their governments have not yet decided what direction they wish to go. Since U.S. policy now requires partners in the Artemis program to sign the accords, one would think that Germany and France and the European Space Agency (ESA) would certainly sign.

They have not, however. Instead, ESA has been in negotiations with China on the subject of space cooperation. If it signs a deal with China it could then become very difficult for it to partner with the U.S.

We might therefore be seeing here the first signs of a true and permanent political split in the alliance between mainland Europe and the United States.

Note too that these political winds signal bad news for Orion. The spacecraft relies on the ESA’s service module for its in-space journeys. If Europe does not sign the accords and instead partners with China, the U.S. will then be faced with either abandoning Orion or finding someone else to build its service module. I suspect that with the coming of cheap, affordable, and efficient private spacecraft, Orion will then die.

An evening pause: A 1948 cartoon, made at the start of the Cold War. It uncannily predicts quite accurately what is happening now, in America, because the Boomer generation and those who followed poo-pooed its lessons. They knew better!

I post it on Memorial Day because I wish to remember what once was.

A visit to a crater near the non-face on Mars

May 31, 2021 1:03 pm Robert Zimmerman

Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on March 12, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It looks down at small six-mile-wide Apt crater in the northern lowland plains of Mars located at about 40 degrees north latitude. The image’s focus were the layers on the crater interior rim as well as the eroded glacial features on the crater’s floor. The color strip suggests [pdf] that the bluish material on the north-facing south interior rim and floor are likely icy, while the tan-colored material seen in the crater’s north half are likely dusty.

While the suggestion of glacial material on the crater’s interior is very typical for many craters in the mid-latitudes, what makes this crater of interest is its location, only a short few miles south of that mesa on Mars that for decades the shallow-minded insisted was a face and proof of an alien Martian civilization.

Today’s blacklisted American: High school group canceled by Democratic Party for criticizing Chinese government

May 31, 2021 10:11 am Robert Zimmerman

Blacklists are back and the Dem’s got ’em: A conservative club at an Illinois high school was forced to disband after two local Democratic Party politicians demanded the school silence the club for putting up a poster that criticized the Chinese government.

The political attack, by state senator Lauren Fine and state representative Jennifer Gong-Gershowitz, caused the club’s sponsor to back out, forcing the club to disband.

“Upon learning of the context of the poster that Glenbrook South’s chapter of Turning Point USA submitted it was taken down, recognizing that it wasn’t in compliance with our policies and guidelines,” District 225 administrators told The College Fix via email through a media representative when asked about the Glenbrook South High School situation. “During the course of that investigation, the sponsor elected to discontinue his sponsorship and the District’s policies require there be a sponsor for all active clubs,” the school officials said.

When asked specifically what policies or guidelines were broken, the district said it took down the poster while there was an investigation and then the sponsor quit, meaning the group had to be disbanded.

The poster, at the link, is incredibly mild, but that’s not acceptable because these bigoted Democrats, Fine and Gong-Gershowitz, see everything through a racial lens. The population of China is almost all Chinese, and if you dare criticize them you must be a bigot, according to the modern Democratic Party.

And if they, on their sainted opinion, think you are a bigot they have the right to get you blacklisted, blackballed, cancelled, fired, and silenced.

Do you vote for such people? Then you believe in blacklisting and oppression and tyranny. Congratulations! You have proved to all that you are not an American.

China successfully launches 1st cargo freighter to its space station

May 31, 2021 9:31 am Robert Zimmerman

On May 29th China successfully launched the first Tianzhou cargo freighter to bring cargo the now-orbiting first module, Tianhe, of its under construction space station, docking there one day later.

They plan to launch the first crew of three to the station in June.
The leaders in the 2021 launch race:

16 SpaceX
14 China
8 Russia
2 Rocket Lab
2 ULA

The U.S still leads China 22 to 14 in the national rankings.

Sorry for the late posting, but I have been off on a cave expedition in a very remote area in Nevada. Needed a break from the news and work. Presently on the long drive home. Posting will resume at full speed later tonight.
