The re-entry capsule of China's first retrievable microgravity satellite, SJ-10, returned safely to Earth on Monday, marking a solid step forward in space science research and application. The recoverable capsule from the research probe, launched on April 6, touched down at around 4:30 p.m. at the planned landing area in Siziwang Banner in north China's Inner Mongolia Autonomous Region, retrievers said.

The capsule was transferred to the China Academy of Space Technology (CAST), which will hand over the equipment aboard the capsule to the Chinese Academy of Sciences (CAS) for further analysis and assessment. The re-entry capsule separated from the orbital module of the probe about 15 minutes before its landing. The latter will remain in orbit before burning away.

It is the 24th retrievable satellite China has successfully recovered. The landing also marked the first time such a satellite has been recovered in Siziwang Banner. During its 12-day journey in space, 19 experiments on microgravity and life sciences were carried out on board.

The experiments included one on the early development of mouse embryos in microgravity to shed light on human reproduction in space, and another on space radiation's effect on the genetic stability of fruit flies and rat cells.

Zhao Huiguang, chief architect of of the SJ-10, said the move forecast a new "spring" for the nation's retrievable satellites project.

Scientific Experiments
For the former experiment, the probe carried over 6,000 mouse embryos in a self-sufficient chamber the size of a microwave oven, according to the CAS.

According to the pictures sent back from a high-resolution camera, the 600 embryos, which were put under the camera, developed from the 2-cell stage, an early-on embryonic cleavage stage, to blastocyst, the stage where noticeable cell differentiation occurs, around 72 hours after SJ-10's launch. The timing was largely in line with embryonic development on Earth, according to CAS.

This is the first reported successful development in mammalian embryos in space in the history of science.

The 15 pieces of equipment which carried 11 experiments loaded on the capsule were in good condition after experiencing the harsh space environment and the return trip.

The probe, which focuses on energy, agriculture, health, will give a boost to the basic research on bio-engineering, new materials and life sciences, in addition to pushing forward the development of China's research on microgravity and space life sciences.

Satellite Technologies
The success of the SJ-10 mission helped verify a series of core technologies of the retrievable satellites, broadening the way for such satellites to expand its role in space science, according to Zhao.

Tang Bochang, general designer of the SJ-10 mission who has long been committed to retrievable satellite development, said that with improved carrying and supporting capabilities and microgravity environment, the SJ-10 model will become China's new generation of scientific experiment platform featuring safer retrieving, capability for medium and long-term on-orbit experiments, greater flexibility and lower cost.

Tang said Chinese scientists will move on to develop the retrievable spacecraft to achieve better performance in energy, control, data management, structure and thermal control.

Qiu Jiawen, chief commander of SJ-10, said that unlike its predecessors, the landing area for SJ-10 was designated in Siziwang Banner, out of consideration of easier recovery and smaller risk for residents' safety.

China is the world's third country to obtain the retrievable satellites technology. Over the last 40 years, China has developed three generations of retrievable satellites in six models for land survey, surveying and mapping, space breeding and other uses.

"Techniques such as thermal protection during reentry, posture control, and soft landing for recovery are still exclusively monopolized by China and very few other countries," Tang said.

Zhao said retrievable satellite has its unique advantages as a space scientific experiment platform.

Before SJ-10, China has used such spacecraft to complete at least 13 space life science experiments, seven experiments for space material processing as well as those regarding space microgravity measuring, space radiation dose measuring and space cell culture.

Lessons learned from Tiangong 1
Sydney, Australia (SPX) Apr 08, 2016
The recent telemetry failure from China's Tiangong 1 space laboratory has lessons for the whole space community. This analyst has previously reported on the issue of Tiangong 1's eventual uncontrolled re-entry, which will happen at a time and a place that cannot be exactly predicted right now. Tiangong 1's return is another hard lesson in the broader issue of re-entering spacecraft. Putting it b ... read more
