  • Scientists track the Chinese Space Station
  • It will fall on Earth soon
  • Scientists are trying to locate the exact location where it will fall

Scientists are monitoring a defunct Chinese space station that is expected to fall to Earth around the end of the month, the largest manmade object to re-enter Earth’s atmosphere in a decade.

The head of the European Space Agency’s debris office, Holger Krag, says China’s Tiangong-1 space station will likely fall to Earth between March 30 and April 3.

Krag said it still not yet known where the space station will hit Earth, but said it would be extremely unlikely for anyone to be injured when it does.

Injury unlikely

“Our experience is that for such large objects typically between 20 and 40 percent of the original mass, of 8.5 tons, will survive re-entry and then could be found on the ground, theoretically,” he said.

“However, to be injured by one of these fragments is extremely unlikely. My estimate is that the probability to be injured by one of these fragments is similar to the probability of being hit by lightning twice in the same year,” Krag added.

He said the space station is expected to fall between the areas of 43 degrees south and 43 degrees north, and everything outside that zone is considered safe.

“Northern Europe including France, Germany, Austria and Switzerland are definitely on the safe side. Southern Europe, the southern part of North America, South Asia, Africa, Australia and also South America are still within the zone today,” he said.

Where will it hit?

Scientists say it is hard to predict where Tiangong-1 will hit Earth in part because of its low orbit and high velocity. They say the space station is travelling 17,400 mph and orbits Earth about every 90 minutes.

Tiangong-1 was launched into orbit in 2011 as China’s first space lab. It carried out orbit experiments in preparation for China’s plan to put a permanent space station into orbit by 2023. VOA

In a surprising move, China’s richest man, Jack Ma, has revealed plans to step down as the Executive Chairman of e-commerce giant Alibaba on Monday to pursue philanthropy in education, paving the way for a change of guard for the $420 billion Internet company that he co-founded.

Ma will turn 54 on Monday, which is also a holiday in China and known as Teacher’s Day.

In an exclusive New York Times interview, the Chinese billionaire said on Friday that his retirement was not the end of an era but “the beginning of an era”.

“I love education,” the Chinese billionaire said, adding that he would be spending more of his time and fortune focused on education.

A former English teacher, Ma co-founded Alibaba with 17 others out of his apartment in Hangzhou, Zhejiang province, in 1999.

He built it into one of the world’s most consequential e-commerce and digital payments companies, transforming how Chinese people shop and pay for things which fuelled his net worth to more than $40 billion, making him China’s richest man.

Ma is revered by many Chinese, some of whom have put his portrait in their homes to worship in the same way that they worship the God of Wealth.

Ma will remain on Alibaba’s board of directors and continue to mentor the company’s management.

The retirement makes Ma one of the first founders among a generation of prominent Chinese Internet entrepreneurs to step down from their companies.

Firms including Alibaba, Tencent, Baidu and JD.com have flourished in recent years, growing to nearly rival American Internet behemoths like Amazon and Google in their size, scope and ambition.

Last month, Alibaba reported a 60 per cent increase in quarterly sales, even as profits fell.

The company’s annual revenue totals about 250 billion yuan ($40 billion).

Alibaba has also changed the way people work in China. Millions of people now run their own shops selling goods on its Taobao ecommerce platform or stream their own videos on its entertainment platforms, The Financial Times reported.

Taobao is estimated to have created almost 37m jobs in China, according to a study last year by Renmin University’s School of Labour and Human Resources, the report added.

For Chinese tycoons to step aside in their 50s is rare; they usually remain at the top of their organisations for many years.

In an interview earlier this week, Ma had signaled that he was thinking about focusing more on philanthropy. He cited the Microsoft co-founder and philanthropist Bill Gates as an example.
