SJ-10 Recoverable Satellite for Space Microgravity Experiments

SJ-10 is a recoverable scientific experiment satellite specially for the space experiments of microgravity physics science and space life science.This mission was officially started on 31 December 2012,and the satellite was launched on 6 April 2016.This paper introduces briefly the SJ-10 mission,the progress of SJ-10 engineering and the project constitution of sciences experiments onboard SJ-10.The purpose of this mission is to discover the law of matter movement and the rule of life activity that cannot be discovered on the ground due to the existence of gravity,and to know the acting mechanism on organisms by the complex radiation of space that cannot be simulated on the ground.

Science Research of Microgravity Satellite SJ-10

The program SJ-10, one of the scientific satellite programs in the Strategic Priority Research Program on Space Science, the Chinese Academy of Sciences, was launched on April 6, 2016. There are totally19 scientific payloads, a multi-function furnace for 8 material researches and three-dimensional cell cultures for the neural stem cell and the hematopoietic stem cell respectively. The recoverable satellite consists mainly of two capsules: a recoverable capsule was recovered on 18 April 2016, with all payloads of life science, the multi-function furnace and the payload for measurement of Soret Coefficients of Crude Oil(SCCO); and an un-recoverable capsule continued to work in additional 3 days with all other physics payloads. The experiments were operated via teleoperations, and all experimental data were received by the ground station in real time.The data and recoverable samples are analyzed by the experiment teams of the program.
