Thanks to CTOnews.com netizens grass Luo Yuzi and Ishihara Rimi for the delivery of the clue to happiness! CTOnews.com, August 20 (Xinhua) A few days ago, with the help of the space station project, China has successfully launched micro-and nano-satellites from the space station on the platform of a series of Tianzhou cargo ships, with a more flexible launch mode, CCTV reported.

At present, the micro-nano satellite launch method that we are familiar with is mainly launched by carrying large rockets, as well as a number of satellite carpool small rockets. In such a launch mode, the satellite, as a "passenger", will be restricted by the launch opportunity and cost of the rocket. The launch of micro-nano satellite in the space station can meet the flexible launch needs of the satellite to a certain extent.

In order to launch satellites from space stations and cargo ships in space, a special ejection mechanism, the micro-nano star, is needed to deploy the launcher. On the one hand, it is necessary to use a medium-sized force to push the satellite out in accordance with the predetermined speed and direction, and on the other hand, it is necessary to ensure that the performance of the dormant satellite is still up to standard after flying in space for a period of time.

Different from releasing the cubic star from the space station through rocket launch, many key technologies need to be solved, such as long-term storage of micro / nano satellites, low impact in orbit release and so on. At present, China has carried out the cube release test through the mission of three Tianzhou cargo spacecraft, and the storage time outside the cube module is more than half a year at most.
