Debris from a massive 21 Ton Chinese booster rocket could fall to Earth early next week

According to US Space Command, which is monitoring the rocket’s course, the remains of the enormous Chinese rocket that delivered a new module to its space station on Monday are predicted to fall to Earth early next week.

At 2:22 p.m. local time on Sunday, July 24, the Wentian laboratory module, which weighed 21 tonnes, was launched from Hainan Island aboard a Long March 5B rocket. The module successfully docked with China’s orbital outpost.

Yet another out-of-control Chinese rocket is sparking concern — a year after one of Beijing's spacecrafts showered debris over the Indian Ocean

After finishing its mission, the rocket commenced an erratic drop through the atmosphere of Earth, and it is unclear where it will land. This is the third time that the nation has been charged with improperly managing space debris from its rocket stage because of the uncontrolled descent.

“It’s a 20-tonne metal object. Although it will break up as it enters the atmosphere, numerous pieces — some of them quite large — will reach the surface,” said Michael Byers, a professor at the University of British Columbia and author of a recent study on the risk of casualties from space debris.

Experts fear that debris from a 21-ton Long March 5B rocket, which was launched to space on Sunday (pictured), may fail to fully burn up as it re-enters Earth's atmosphere

Space debris poses extremely minimal risk to humans, Byers explained, but it’s possible that larger parts could cause damage if it lands in inhabited regions.

“This risk is entirely avoidable since technologies and mission designs now exist that can provide controlled reentries (usually into remote areas of oceans) instead of uncontrolled and therefore entire random ones,” he said via email.

He continued by saying that the rocket’s re-entry zone was physically restricted to latitudes between 41 degrees south and 41 degrees north of the equator.

According to a spokeswoman for the US Space Command, the US will monitor the Chinese rocket’s return to Earth.

Based on varying atmospheric conditions, the exact entry point of the rocket stage into Earth’s atmosphere “cannot be pinpointed until within hours of its reentry,” the spokesperson said, but it is estimated to reenter the Earth’s atmosphere around August 1.

Daily reports on the location of the 18th Space Defense Squadron, a US military unit that monitors reentries, will also be given.

According to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, space debris that weighs more than 2.2 tonnes is frequently carried to a precise place during its first orbit around the planet.

“The point is that things that big are normally not put in orbit without an active control system,” he said.

The Wentian lab module was launched atop a Long March 5B rocket from Hainan Island at 2:22 p.m. local time on Sunday, July 24.

With “no active control system and no re-startable engine to boost it back down to Earth… it just tumbles along in orbit and eventually burns up due to friction with the atmosphere.”

China was heavily criticized last year for its handling of space debris after it launched another module on a similar rocket. Its remnants plunged into the Indian Ocean near the Maldives 10 days after the launch.

NASA said China failed to “meet responsible standards.”

“Spacefaring nations must minimize the risks to people and property on Earth of re-entries of space objects and maximize transparency regarding those operations,” said NASA Administrator Bill Nelson at the time.

In response to criticism, China accused the US of “acting against their conscience” and being “anti-intellectual” by “hyping up anxieties” regarding the rocket descent.

2020 saw the uncontrolled re-entry of a Chinese rocket core, which weighed close to 20 tonnes and flew over Los Angeles and Central Park in New York City before crashing into the Atlantic Ocean.

Every day, space debris like defunct satellites reenter the Earth’s atmosphere, but most of it is undetected because it burns up before it can impact the earth.

Only larger space debris, such as spacecraft and rocket parts, poses even a slight risk to people and ground-based infrastructure.

Chinese scientists develop robot fish that gobble up microplastics

Chinese researchers have created tiny robot fish that consume microplastics as an innovative method of reducing ocean pollution.

These tiny, touchable bots, which measure just 1.3 cm, can already ingest microplastics in shallow water, according to a group of Chinese researchers from Sichuan University in the southwest of the country.

Microplastics are tiny fragments of plastic that separate from larger objects like bottles or synthetic garments. They are almost omnipresent on Earth and pose a hazard to both human and animal health as well as the environment.

The tiny particles have been identified in human blood, lungs, and even developing fetuses in addition to finding their way into the food and water we consume.

According to Wang Yuyan, one of the researchers who built the bot, scientists in China are now trying to enable the robot fish to collect microplastics deeper in the water, above the surface, and to offer data that analyses marine pollution in real-time.

“We developed such a lightweight miniaturized robot. It can be used in many ways, for example in biomedical or hazardous operations, such as a small robot that can be localized to a part of your body to help you eliminate some disease”.

The black robot fish is exposed to light, which helps it move its body and fins. To prevent the fish from striking other animals or even ships, scientists can control it using light.

Being constructed of polyurethane, which is also biocompatible, it can be safely digested if it is accidentally consumed by other fish, according to Wang.

Even when it is injured, the fish has the capacity to absorb contaminants and repair itself. It can swim faster than the majority of artificial soft robots—up to 2.76 body lengths per second.

“We are mostly working on collection. It is like a sampling robot and it can be used repeatedly,” Wang said.

At the United Nations Ocean Conference last month, experts and environmentalists warned that plastic waste was an increasing menace to both humans and marine life.

According to studies, 11 million tonnes of plastic enter the ocean each year, and if manufacturing and use of disposable containers are not decreased, that number might quadruple by 2040.

China uses ‘mind-reading AI’ to test the loyalty of Communist Party members

An AI program can “determine the level of acceptability for ideological and political instruction” by reading brainwaves and facial expressions. According to Didi Tang, a Times reporter in Beijing, the technology was created by scientists at the Hefei Comprehensive National Science Centre.

Communist Party members’ facial expressions and brain waves can be analyzed to gauge their openness to “thought instruction.”

China has reportedly created an artificial intelligence (AI) system that can check the loyalty of Communist Party members (stoke image)

Tang claims that an article describing the technique was published online on July 1 and quickly removed.

The article said: ‘On one hand, it can judge how party members have accepted thought and political education. 

‘On the other hand, it will provide real data for thought and political education so it can be improved and enriched.’

The AI technology will strengthen Communist Party members’ “confidence and determination” to “be grateful to the party, listen to the party, and follow the party.”

Hefei Comprehensive National Science Centre has reportedly pushed 43 Communist Party members who are also members of the research team to test the technology.

A researcher was seen entering a kiosk, sitting in front of a screen, and showing articles highlighting party policy and accomplishments in a video that was included with the story but has since been removed.

‘The kiosk can see the researcher’s expressions, possibly via surveillance cameras,’ Tang says

The 'Study Xi' app tracks the amount of time users spend browsing inspirational quotes and following his speeches and travels

The location of the brainwave-reading technology in the kiosk and the implementation of the entire system to keep an eye on the nation’s millions of Communist Party members are both unknown.

However, it seems that reading people’s brain waves is nothing new for China; in fact, the South China Morning Post revealed in 2018 that Hangzhou manufacturing workers were subjected to brain-scanning equipment.

This entailed employing artificial intelligence algorithms to identify emotional spikes like melancholy, anxiety, or fury using brain-reading helmets to read a worker’s emotions.

According to reports, President Xi Jinping’s Communist Party, which currently controls China, considers “thought and political education” to be crucial to maintaining party allegiance.

For its members, the party already has an “indoctrination app” named “Xuexi Qiangguo,” which translates to “Study to make China powerful.”

The 96.77 million users of the app are required to gain points by watching movies, reading articles, and responding to questions about historical Communist figures.

It keeps track of how long users spend looking through President Jinping’s motivational words and skimming through brief recordings of his speeches and tours.

According to AFP, members can exchange their points for items like doughnuts and tablets.

As a result of its use of sophisticated surveillance tools, like security cameras with facial recognition capabilities and police applications that allow them to access personal data from smartphones at checkpoints, China’s government has come under increased scrutiny.

China is renowned for deploying cutting-edge technology to monitor its population, most notably a social grading system like to that in Black Mirror to “restore morals” and blacklist “untrustworthy” citizens.

China built an AI prosecutor that can charge people with crimes with an accuracy rate of more than 97%, it was reported last year.

The eight most frequent crimes in Shanghai may be identified by this algorithm, which was “trained” using 17,000 actual incidents from 2015 to 2020.

These include credit card fraud, gambling offenses, reckless driving, theft, fraud, intentional injury, and disrupting official duties—a word used to stifle dissent in China.
