Chinese space station to plummet back to Earth, officials say

China's first space station, the 9.4 ton Tiangong-1, will burn up in Earth's atmosphere sometime in the second half of next year, say Chinese officials.

China's first-ever space lab will die a fiery death in Earth's atmosphere toward the end of next year, Chinese officials said.

The 9.4-ton (8.5 metric tons) Tiangong-1 spacecraft is currently intact and orbiting Earth at an altitude of 230 miles (370 kilometers), according to Wu Ping, deputy director of China's Manned Space Engineering office. That's a bit lower than the International Space Station, which usually stays about 250 miles (400 km) above the planet's surface.

"Based on our calculation and analysis, most parts of the space lab will burn up during falling," she said during a news conference Wednesday (Sept. 14), according to China's state-run Xinhua news agency.

China is monitoring Tiangong-1 (whose name means "Heavenly Palace" in Mandarin) closely and will issue the appropriate warnings if the space lab threatens to hit a satellite, Wu added. She said that China will release a forecast of Tiangong-1's fall to Earth "if necessary," according to Xinhua.

The update from Wu seems to confirm speculation that China is no longer in control of the 34-foot-long (10.3 meters) Tiangong-1, which launched in September 2011 to test out docking technologies and other skills that China will need to build its planned space station in the early 2020s. 

After all, if operators were still controlling the space lab, they could steer it to a guided re-entry over an empty stretch of ocean at a specified time.

Three spacecraft docked with Tiagong-1 during its operational life — Shenzhou-8 in November 2011, Shenzhou-9 in June 2012 and Shenzhou-10 in June 2013. The latter two missions were crewed, each carrying three Chinese "taikonauts" up to the space lab.

Tiangong-1 stopped sending data back to Earth in March 2016, officially ending the space lab's mission. But its successor is now aloft: Tiangong-2 launched atop a Long March 2F rocket on Sept. 15 from the Jiuquan Satellite Launch Center in northwestern China.

Two taikonauts are scheduled to arrive at Tiangong-2 in mid- to late October for a 30-day stay, Chinese officials have said. (The Shenzhou-9 and Shenzhou-10 crews spent eight and 12 days aboard Tiangong-1, respectively.)

China is not part of the multinational consortium, led by the United States and Russia, that operates the 440-ton (400 metric ton) International Space Station. China aims to have its own 60-ton (54 metric tons) space station up and running in Earth orbit by 2022 or so.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
