Retrievable scientific research satellite:

China put into space a retrievable scientific research satellite, the SJ-10, in the early hours of April 6 to facilitate the study of microgravity and space life science. During its 12-day trip, the satellite carried out 19 experiments, including one on the early development of mouse embryos in microgravity, to shed light on human reproduction in space, and another on space radiation’s effects on the genetic stability of fruit flies and rat cells. The satellite’s re-entry capsule landed safely on April 18.
