Revised Long March 5B crash window

Aerospace's revised Long March 5B crash window
Click for original image.

The map above, reduced and adjusted to post here, shows today’s revised estimate by the Aerospace Corporation for where and when the 21-ton core stage of China’s Long March 5B rocket, launched on April 29th, will hit the ground. The reentry window has now narrowed to 22 hours, and is centered on May 8th at 10:29 pm (Eastern) over the Indian Ocean, just off the southwest coast of Australia. The yellow orbital tracks are after that centerpoint, while the blue are before. The tick marks indicate five minute intervals.

Expect these updates to come more frequently and continue to narrow in the next two days as the orbit continues to decay. Right now, if the stage comes down a little later than predicted there is ample opportunity for it to hit either Australia or the United States. Should it come down earlier, it right now could hit either Africa or Spain.

Note that the chances of this stage doing any real harm is quite slim, even it if lands on a populated area. It will break up during reentry so that any pieces that hit the ground will be much smaller. If anything, the debris will resemble somewhat the wreckage that fell when the space shuttle Columbia broke up over the U.S. in 2003 during its return to Earth. The impact of that wreckage injured no one on the ground, even as it did kill seven astronauts. Expect the same with China’s core stage.

The issue here is not the danger, but China’s gross negligence and violation of its treaty obligations in launching this rocket knowing the core stage was going to do this. No more Long March 5B launches can occur without them fixing the problem so that future core stages can be brought back to Earth in a controlled and safe manner.

Long March 5B crash window narrows, aims for U.S.

Long March 5B final orbits

Zoom into Long March 5B's track over the U.S.

The reentry window of the 21-ton core stage for China’s Long March 5B rocket, launched on April 29th, has now narrowed to only 28 hours, with the centerpoint of that window on May 9th over the Pacific, only about 20 minutes before reaching Mexico and the continental U.S.

The update by the Aerospace Corporation is shown in the maps above and to the right. With the right map I have zoomed into the section over the U.S. to show the potential path of this core stage should it come down a bit later than presently predicted.

The circled point is centerpoint of the reentry window. The yellow orbital tracks are after that point, with the blue tracks previous. The tick marks indicate 15-minute intervals.

As you can see, the centerpoint is only about 20 minutes before the stage crosses Mexico and begins a half hour traverse above the continental United States from Texas to Maryland. If the stage should manage to stay up for another full orbit it will once again traverse the continental U.S., this crossing from San Diego to Cape Cod.

If the stage comes down early instead it could land anywhere from southern Europe to Australia, with the Middle East and India in between.

As I have noted already, China designed and launched this rocket knowing it was creating a giant piece of space junk that was going to fall on someone’s head. Just as that communist government has not cared that it has been dumping first stages on its own people for decades, it apparently does not care that it is dumping even bigger first stages on everyone else. The Long March 5B is the rocket they are using to launch the modules to their space station, as well as many of the future planetary missions to the Moon and Mars. And every time they launch it they will be dumping a core stage on someone, a direct violation of the Outer Space Treaty that China has signed.

The world’s governments should be outraged, and teaming up to demand that either China change this situation or delay future Long March 5B launches, or face serious financial consequences. Sadly, I do not expect this, as our present political class is either incompetent or corrupt and in the deep financial pockets of the Chinese.

Today’s blacklisted American: Any conservative on Twitter

Twitter's idea of debate
Show trials: Debate as Twitter sees it.

Blacklists are back and Twitter’s got ’em: Rather than write today about a single specific individual being blacklisted and destroyed by today’s intolerant left, let’s take a look at one of that left’s most intolerant and oppressive blacklister, Twitter.

Like all the big tech social media companies such as Google and Facebook, Twitter is essentially run like a leftwing fiefdom. Though it allows conservative writers to post there, it makes it very clear that they are always under a probation that can be withdrawn immediately if someone in company’s workforce finds itself offended or disagreeing with something that conservative posted.

For example, in January religious radio host Michael Brown got banned from Twitter for twelve hours for simply posting a tweet where he asked this simple question: “Will I get punished by Twitter for saying that, in God’s sight, ‘Rachel’ Levine (nominated by Biden to be his assistant secretary for HHS) is a man?”

Today’s blacklisted American: controversial Nick Fuentes

Banned by the Biden administration
Banned by the Biden administration

Blacklists are back and the Dems’ have got ’em: Routinely called a racist, bigot, white supremacist, and (of course) an alt-right conservative by the mainstream press, controversial Nick Fuentes’ track record is far from that straight-forward. Though it appears he has often taken some ugly positions and made some even more ugly statements, he apparently has never done anything illegal or outright bigoted.

No matter to the Biden administration and the TSA. They have blacklisted him, banning him from flying on any American airline.

Moreover, the federal government is not the only one blacklisting Fuentes because they don’t like his opinions. As Fuentes himself noted in a April 27th tweet:

Since attending President Trump’s rally on the Ellipse on January 6th I’ve been:

-Banned from AirBnB, Facebook, Instagram, DLive, and Coinbase
-Banned from every payment processor
-Had a bank account frozen
-Put on the no-fly list

And I haven’t even done anything wrong!

The most important line in his tweet is the last one. What he has said might be wrong-headed, bigoted, or stupid, but in a free country that defends its first amendment, he would be within his rights to say it, and would have broken no laws by doing so.

We no longer live in that long gone free nation. Now we live in a place that routinely uses power to squash radical positions, except when those opinions happen to be leftist radical positions. Those Marxist opinions are always blessed with immunity, no matter how bigoted or vile. In fact, if you dare to criticize the dominant Marxist and bigoted culture in any way at all, you are guaranteed to be called a bigot and are likely to be blacklisted, like Fuentes, for doing so.

Long March 5B crash estimate as of today

May 3rd prediction of Long March 5B crash
Click for full image.

According to estimates this morning by the Aerospace Corporation, the 21-ton core stage of China’s Long March 5B rocket will come crashing down to Earth sometime on May 10th, plus or minus 41 hours.

Their map to the right illustrates all the orbits that will take place during that time period, which in turn shows all the possible places that core stage might land. For example, though the center point in that time period puts the stage down in the Pacific west of South America, should it go down just a little more than two orbits later it will then be crossing over the entire continental United States, with even a very slim chance it could land on my own house in Arizona! If it should come down a little early instead it could land on Europe, the Middle East, India, or Australia.

This estimate is very very uncertain, and will be refined in the days ahead, though because of the chaotic nature of decaying orbits it will be impossible to refine it to less than half an orbit, even on the day of its return.

Nor can anyone do anything about it. Large sections of this big piece of hardware is going to hit the ground in an uncontrolled manner. And China, a signatory to the Outer Space Treaty which forbids exactly this sort of uncontrolled reentry, launched it anyway.

China’s Long March 4C rocket successfully launches Earth observation satellite

China yesterday successfully launched an Earth observation satellite using its Long March 4C rocket from its interior Jiuquan Satellite Launch Center in inner Mongolia. Its first stage, using toxic fuels, will fall on land somewhere in China.

The leaders in the 2021 launch race:

12 SpaceX
11 China
7 Russia
2 Rocket Lab

The U.S. still leads China 17 to 11 in the national rankings.

China’s 21-ton Long March 5B core stage to make uncontrolled re-entry

For the second time in two launches, the 21-ton core stage of China’s Long March 5B rocket is about to make uncontrolled re-entry, with a mass large enough that some part of it is certain to hit the ground.

Where and when the new Long March 5B stage will land is impossible to predict. The decay of its orbit will increase as atmospheric drag brings it down into more denser. The speed of this process depends on the size and density of the object and variables include atmospheric variations and fluctuations, which are themselves influenced by solar activity and other factors.

The high speed of the rocket body means it orbits the Earth roughly every 90 minutes and so a change of just a few minutes in reentry time results in reentry point thousands of kilometers away.

The Long March 5B core stage’s orbital inclination of 41.5 degrees means the rocket body passes a little farther north than New York, Madrid and Beijing and as far south as southern Chile and Wellington, New Zealand, and could make its reentry at any point within this area.

The previous core stage hit the Atlantic Ocean six days after launch in May 2020. Had it come down fifteen to thirty minutes earlier it would have come down on U.S. soil, possibly even on top of the New York metropolitan area.

China’s design for this rocket means that every single launch will result in similar potential disasters. They cannot restart the core stage’s engines after cut-off, so that once it has delivered its payload it is nothing more than a very big and uncontrolled brick that has to hit the ground somewhere.

This is a direct violation of the Outer Space Treaty, which China is a signatory. The treaty makes signatories liable for any damage from an uncontrolled re-entry, and requires them to take action to prevent such events from occurring.

China it appears doesn’t care much about the treaties it signs. The first time could be rung up to a mistake. The second time is intentional and tells us that this country will not honor any of its obligations anywhere else, if it decides it can get away with it.

Today’s blacklisted Americans: Any conservative trying to get published by Simon & Schuster

Cancelled Bill of Rights
No longer valid for too many employees
at Simon & Schuster.

Blacklists are back and book publishers want ’em: A petition of about 14% of the workforce at the book publisher Simon & Schuster is demanding that all former Trump administration officials be blacklisted from publication.

The petition demanding the New York publishing conglomerate to stop treating “the Trump administration as a ‘normal’ chapter in American history” collected 216 internal signatures, representing approximately 14% of the company’s workforce, and support from several thousand nonemployees, according to the Wall Street Journal. The petition singled out a planned two-part autobiography to be authored by former Vice President Mike Pence, which the publisher’s employees alleged amounted to support for “racism, sexism, homophobia, transphobia, anti-Blackness, xenophobia, misogyny, ableism, islamophobia, antisemitism, and violence” in the online petition.

While the publisher has rejected the call to cancel Pence’s autobiography, it still has a track record of blacklisting conservatives. » Read more

FAA approves next three Starship test flights with prototype #15

Capitalism in space: In a statement today the FAA announced that it has approved next three test flights of SpaceX’s Starship prototype #15.

From the statement:

The FAA has authorized the next three launches or the SpaceX Starship prototype. The agency approved multiple launches because SpaceX is making few changes on the launch vehicle and relied on the FAA’s approved methodology to calculate the risk to the public. The FAA authorized the launches on Wednesday, April 28.

This likely means that SpaceX will try a flight tomorrow.

Today’s blacklisted American: Law professor under investigation for criticizing China

Cancelled Bill of Rights
Doesn’t exist at the University of San Diego.

They’re coming for you next: A law professor at the University of San Diego, Tom Smith, is now under formal investigation and could possibly be fired for a blog post on his own webpage where he strongly criticized China and its role in the start of COVID-19.

When he first published the March 10 post, the USD Law School placed him under investigation, citing complaints of bias. Now, the law school has sent his case to administration for a formal review.

The review comes as a petition circulates demanding Smith resign or be fired, alleging he has a history of saying and writing things some find offensive.

Signed by the USD Law Student Bar Association presidents for this school year and the next, they claim in the petition Smith’s alleged comments have left some in the USD law community feeling vulnerable and helpless so that students cannot balance their studies or “prepare for our futures in the legal profession.” [emphasis mine]

Beside the fact that it is utterly wrong for the university to investigate this man for simply expressing his opinion on line, the highlighted words — “feeling vulnerable and helpless” — illustrate starkly the total close-mindedness of the left’s modern blacklisting effort to any opinions outside its frame of reference.

Starship prototype #15 completes 2nd static fire test, waits FAA approval for flight

Capitalism in space: SpaceX’s 15th Starship prototype completed its second static fire test in three days yesterday, and is presently poised to do its first test flight.

The scheduled road closures in Boca Chica suggest that they are aiming for either April 30th, May 1st, or May 2nd. However, it also appears they are awaiting FAA approval, which could be why they did a second static fire test. They can’t fly so rather than do nothing they reconfigured that second static fire to test the landing burn.

Musk returned to Twitter to state that this was a header tank test and that all looked good. This could mean Monday’s test was a launch static fire while Tuesday’s test was more of a landing burn static fire as the header tanks are used to supply landing propellants.

It also appears that SpaceX has had its flight application sitting at the FAA for about a week, with no action. Thus, it is the federal bureaucracy that appears to be slowing things down at this moment.

Today’s blacklisted American: Student is persecuted by university for asking a question

Cancelled Bill of Rights
No longer exists at the University of Virginia

They’re coming for you next: Because medical student Kieran Bhattacharya dared to question the scientific validity of the term “microaggressions” during a panel discussion, the University of Virginia’s School of Medicine began an investigation that accused Bhattacharya of being a threat to others and banned him from the campus.

Here was what the student said.

“Thank you for your presentation,” said Bhattacharya, according to an audio recording of the event. “I had a few questions, just to clarify your definition of microaggressions. Is it a requirement, to be a victim of microaggression, that you are a member of a marginalized group?”

Adams replied that it wasn’t a requirement.

Bhattacharya suggested that this was contradictory, since a slide in her presentation had defined microaggressions as negative interactions with members of marginalized groups. Adams and Bhattacharya then clashed for a few minutes about how to define the term. It was a polite disagreement. Adams generally maintained that microaggression theory was a broad and important topic and that the slights caused real harm. Bhattacharya expressed a scientific skepticism that a microaggression could be distinguished from an unintentionally rude statement. His doubts were well-founded given that microaggression theory is not a particularly rigorous concept.

You can listen to the audio of this exchange here, beginning at about 28 minutes. Bhattacharya is respectful and calm, and is asking legitimate questions. It appears his main concern was the blanket vagueness of the term that allows anyone to claim a microaggression for almost any statement or act.

Apparently, the organizers of the event then decided that his questions were a microaggression in themselves, for which he must be punished.
