China has put into orbit a satellite aimed at studying micro-gravity and life in space. The retrievable scientific research probe "S J TEN" was on the back of a rocket launched at China's Gobi desert early Wednesday.

The chief scientist of the SJ-10 mission said the probe will conduct 28 tests on micro-gravity physics and space bio-technology, never been done before by China or any country. The satellite will also do experiments in partnership between the European Space Agency and the National Space Science Center of the Chinese Academy of Sciences, or CAS.

SJ-10 is the second of four scientific satellites, as well as the first retrievable one under a space program of CAS.
