Since I was a young child Mars held a special fascination for me. It was so close and yet so faraway. I have never doubted that it once had advanced life and still has remnants of that life now. I am a dedicated member of the Mars Society,Norcal Mars Society National Space Society, Planetary Society, And the SETI Institute. I am a supporter of Explore Mars, Inc. I'm a great admirer of Elon Musk and SpaceX. I have a strong feeling that Space X will send a human to Mars first.
Not knowing when it’s going to come down translates as not knowing where its going to come down
Wu Ping, deputy director of the manned space engineering office, said Tiangong-1 has been in service for four and a half years - two and a half years longer than it was designed for.
"Based on our calculation and analysis, most parts of the space lab will burn up during falling," she said, adding that it was unlikely to affect aviation activities or cause damage to the ground.
Ms Wu said China highly valued the management of space debris "conducting research and tests on space debris mitigation and cleaning", Xinhua reported.
"Now, China will continue to monitor Tiangong-1 and strengthen early warning for possible collision with objects."
Ms Wu said China would release a forecast for the space station's fall to Earth internationally if necessary.
Harvard astrophysicist Jonathan McDowell said the news suggested China had lost control of the station - and if so, it would be impossible to predict where the debris would land.
“You really can’t steer these things,” he told the Guardian.
“Even a couple of days before it re-enters we probably won’t know better than six or seven hours, plus or minus, when it’s going to come down.
"Not knowing when it’s going to come down translates as not knowing where its going to come down.”
The news comes as technical problems prompted Russia's space agency to postpone the launch of its next manned Soyuz spaceship to the International Space Station, which was originally scheduled forSeptember 23.
