  • 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

Apple Launches a $300 Million Fund to Bring Clean Energy to China

In September 2016, Apple opened its first China R&D centre in Beijing's Zhongguancun Science Park, often referred to as "China's Silicon Valley"

Amid heightened trade tensions between the US and China, tech giant Apple has joined hands with its suppliers to launch a $300 million clean energy fund in China.

The “China Clean Energy Fund” will invest in and develop clean-energy projects totalling more than 1 gigawatt of renewable energy in China, the equivalent of powering nearly 1 million homes, Apple said in a statement on Thursday.

“At Apple, we are proud to join with companies that are stepping up to address the climate challenge,” said Lisa Jackson, Apple’s Vice President of Environment, Policy and Social Initiatives.

The Cupertino, California-headquartered tech giant said 10 of its initial suppliers have come forward to jointly invest in the nearly $300 million fund over the next four years.

“We’re thrilled so many of our suppliers are participating in the fund and hope this model can be replicated globally to help businesses of all sizes make a significant positive impact on our planet,” Jackson said.

By virtue of its size and scale, the China Clean Energy Fund will give its participants the advantage of greater purchasing power and the ability to attain more attractive and diverse clean energy solutions.

The China Clean Energy Fund will be managed through a third party, DWS Group, which specialises in sustainable investments and will also invest in the fund, Apple said.

The announcement to invest in the clean energy fund in China follows Apple’s announcement earlier in 2018 that its global facilities are powered by 100 per cent clean energy and the launch of its Supplier Clean Energy Programme in 2015.
