China tonight successfully launched a new oceanography satellite using its Long March 4B rocket, completing a three satellite constellation.
No word on whether the rocket’s first stage landed on any villages in the interior of China.

The new colonial movement: On May 15th China rolled out the Long March 7 rocket that on May 20th will carry the first Tianzhou cargo freighter to the already launched core module of its space station.
Tianzhou-2 will carry 4.69 tons of cargo in a pressurized segment and 1.95 tons of propellant, according to the China Manned Space Agency (CMSA).
Meanwhile, the core stage, dubbed Tianhe, has successfully completed its on-orbit checkouts and has placed itself in the right orbit for the arrival of Tianzhou.
If all goes right with this cargo mission, China is targeting a June launch for the station’s first three-man crew, who will attempt to stay at the station for three months.
Do not expect much information to be released by China during these missions. Like the Soviet Union of old, and as they have been doing routinely since their space program began to gear up in the past decade, they will only make periodic terse announcements, all of which will contain only the most superficial of information. Only much later will more be learned, usually many years after the fact when its news value has vanished and it only concerns historians and space buffs.
At this moment we do not have confirmation that China’s rover Zhurong landed safely on Mars. Assuming it did, the mosaic to the right, made from two images from Mars Reconnaissance Orbiter’s (MRO) context camera, shows that landing zone, with the white cross indicating the centerpoint of the suspected landing site, as leaked to the Chinese press back in October 2020.
The red boxes are the only two images released by China that were taken by its Tianwen-1 orbiter of this landing zone. The two white boxes show the areas covered by two of the seven or so photographs taken by MRO’s high resolution camera since that location was revealed. Below is a map showing all the images MRO has taken of this location.

Despite more than 48 hours having passed since China announced the successful landing of its Zhurong rover on Mars in the northern lowland plain of Utopia Planitia, no images or data of any kind has been released by that nation or its space agency.
It is very possible that this is totally expected, since they have always said they will need about a week of checkouts before they rollled the rover off the lander and begin its operations.
At the same time, China has been very very creative with providing early images for all its planetary missions. For example, within hours of landing they had released images from their Chang’e-5 lunar sample return lander. Similarly, only hours after Chang’e-4 landed on the far side of the Moon with its Yutu-2 rover China released images.
They did the exact same thing when Chang’e-3 landed in 2013 with its Yutu-1 rover.
I can’t imagine they don’t have some cameras on the Mars lander to snap pictures of the horizon or the ground directly below. They might not, but if so the lack would be truly astonishing.
It is also possible China is holding the data close for any number of political reasons, though this doesn’t make much sense since the whole political point of these planetary missions is to sell China to the world.
The more time that passes with no confirmation data, the more it will appear that something is wrong. If this conclusion is incorrect, China needs to act now to dispel these doubts.
The new colonial movement: China’s today successfully landed its Zhurong rover on the northern lowland plains of Mars dubbed Utopia Planitia.
China’s lander and rover began their descent to the surface at about 4:00 p.m. EDT (2000 GMT) by separating from the Tianwen-1 orbiter, which since March has been used to capture imagery of the targeted landing site for study. An aeroshell protected the stacked probes as they plunged into the atmosphere at 3 miles per second (4.8 km per second), generating tremendous heat in the process.
Once inside the atmosphere, while traveling at supersonic speeds, the spacecraft deployed a 2,150-square-foot (200 sq. meter) parachute to slow its approach to less than 328 feet per second (100 m per second). China based the canopy design on the parachutes it has used on Shenzhou missions to return astronauts to Earth.
Finally, the Tianwen-1 lander fired thrusters similar to the type on China’s Chang’e lunar landers to make the final descent. A laser range finder and a velocity sensor helped guide the craft as it hovered at about 328 feet (100 m) to identify obstacles and measure the slopes of the surface before touching down safely.
We don’t yet know the exact touchdown point. The image above is a mosaic of two wide angle photos from the context camera on Mars Reconnaissance Orbiter (MRO), with the white cross marking the spot previously leaked by the Chinese press as the landing site. The white box shows the area covered by the only high resolution MRO photo, as of October 2020. Since then MRO has taken a number of additional high resolution images of this area. The red boxes are the areas covered by the only two high resolution images released by China from its Tianwen-1 Mars orbiter
Note that the rover is actually not yet on the ground. It still sits on the lander. A ramp will be deployed and it will then roll down on the ground to begin what China says is a planned 90 day mission, with the most important data likely coming from the rover’s ground penetrating radar, looking for underground ice.
Around 10:15 pm (Eastern) the Long March 5B core stage reentered the atmosphere over the Arabian Peninsula, with pieces landing in the Indian Ocean north of the Maldives to the southwest of India.
China has attempted to minimize its behavior here, claiming that most of the rocket burned up and that the chance of any damage was low. Big deal! If you are a responsible spacefaring nation you don’t build rockets that are designed to do this.
Remember, at least three more Long March 5B launches are scheduled in the next the years. As presently designed all will dump that core stage somewhere on Earth in an entirely uncontrolled manner.

The Aerospace Corporation has once again narrowed the reentry window for the 21-ton core stage of China’s Long March 5B rocket, launched on April 29th, as shown by the map above. The window is now only eleven hours long, centered over a point in the Indian Ocean at just before midnight on May 8th. The yellow tracks indicate its path after that centerpoint, while the blue lines show its path prior to it. Tick marks show five minute intervals.
The last orbit as shown by this prediction puts it over the following land areas. If the core stage crashes 5 to 20 minutes early, it would land anywhere from Spain to Africa. Another fifteen minutes earlier and Florida and Mexico would be in the landing zone. If it lands 45 to 50 minutes later, it will land somewhere on the continental United States.
China however might be lucky with this booster. The centerpoint of the prediction has definitely begun to stabilize around the Indian Ocean.
With future boosters, who knows? China plans at least three more Long March 5B launches, two in ’22 to launch modules for its space station, and one in ’24 to launch a Hubble-class space telescope to fly in formation with that space station. We shall see this same Keystone cop charade on all three flights, with the core stage tumbling out-of-control and falling back to Earth to crash somewhere that cannot be predicted.
China today used its Long March 2C rocket to put in orbit what it calls a “remote-sensing” satellite that is likely for use by its military.
Launched from an interior spaceport, this rocket’s first stage (using very toxic hypergolic fuels) will fall to Earth somewhere in China’s Guizhou Province. This has been China’s standard operating procedure for decades, sometimes resulting in such stages landing near residential areas.

The Biden administration will make no attempt to shoot down the 21-ton core stage of China’s Long March 5B rocket, according to the Defense secretary Lloyd Austin:
At this point we don’t have a plan to shoot the rocket down. We’re hopeful it will land in a place where it won’t harm anyone. Hopefully in the ocean or someplace like that. I think this speaks to the fact that for those of us who operate in the space domain that there should be a requirement to operate in a safe and thoughtful mode and make sure that we take those kinds of things into consideration as we plan and conduct operations.
Meanwhile, the predicted reentry window has shrunk again, to 16 hours, and shifted so that its centerpoint is now over Egypt, as shown on this map by the Aerospace Corporation:

Today’s most recent prediction by the Aerospace Corporation for the reentry of China’s out-of-control Long March 5B 21-ton core stage is still centered at 10:34 pm (Eastern) on May 8th, with a total uncertainty of 21 hours. As the company notes,
The prediction is currently holding steady for Saturday evening for the US, and the error bars are shrinking.
As shown on the map to the right, the centerpoint is just off the southwest coast of Australia. However, with a window 21 hours long, the booster could still come down in a large number of high population locations.

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.
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.

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 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.

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.

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.

Twas a busy evening. SpaceX successfully put 60 more Starlink satellites into orbit using its Falcon 9 rocket, with the first stage successfully completing its seventh flight, landing safely on the drone ship in the Atlantic.
China in turn successfully used its Long March 5B rocket to place in orbit the core module, dubbed Tianhe, of its planned space station. This is the first of eleven launches in the next two years to assemble the station’s initial configuration, including cargo and manned missions along the way.
The SpaceX live stream is at the link. I have embedded China’s English language live stream of the Tianhe launch below the fold. The launch is about 52 minutes in.

China today used its Long March 6 rocket, designed to launch small satellites, to place what the country’s state-run media describes as “nine commercial satellites.”
Two satellites apparently are aimed at Earth observation, while the others are testing various satellite designs.

The new colonial movement: Yesterday China and Russia announced that they have signed an agreement to jointly work together to build a base on the Moon.
The link above is from the Chinese state-run press, stating:
In a joint statement issued at the conference, the CNSA and Roscosmos said the moon station will be open to all interested countries, international organizations and partners in terms of planning, design, research, development, implementation and operation at all stages and levels of the project.
The Russian state-run press made a similar announcement.
The new Cold War in space is beginning to shape up. On one side will be free enterprise, led by the United States and the many private companies working independently to make their own profits in space, and on the other side will be the former communist nations whose cultures require all such efforts be controlled from the top by the government.
And like the Cold War of the 20th century, the big question will be the actions of third parties, like Europe, India, Japan, the UAE, and other new space-faring nations. Will they join with the U.S., or join China and Russia to gang up on private enterprise? Right now I will not be surprised if all these countries eventually join the Chinese/Russian effort. Worse, I have great doubts about the U.S. government’s commitment to the capitalist path it is presently taking. If enough pressure was applied by these authoritarian regimes we should not be surprised if our generally authoritarian present government decides to join them as well, using their combined power to squelch freedom and private enterprise in space.
The battle is drawn, but the forces for liberty and freedom are sadly outnumbered.
The new colonial movement: The Chinese state-run press today announced that it has chosen Zhurong, a traditional Chinese fire god, as the name of the rover that is presently orbiting Mars on its Tianwen-1 orbiter and is targeting a landing sometime in mid-May.
They note that this name matches well with the Chinese name for Mars, “Huo Xing,” or fire star.
The announcement provided little additional information, other than stating that the prime landing site is in the previously announced Utopia Planitia region, which suggests the high resolutions images being taken by Tianwen-1 (unreleased by China) continue to show no reason to change that target.
