Fast Science and Technology, June 3 news, as a tool to transport astronauts into space and return to the earth, the importance of the spacecraft is self-evident.

According to the plan, the astronauts of Shenzhou 15 and Shenzhou 16 carried out an in-orbit handover ceremony on June 2, and the Shenzhou 15 astronauts have completed all the scheduled tasks.Will return to the Dongfeng landing site tomorrow (4) aboard the Shenzhou 15 manned spacecraft.。

The deputy chief designer of the manned spacecraft system of the Fifth Academy of Aerospace Science and Technology Group said that this change affects the whole body and affects a wide range of areas. InUnder the premise of meeting the requirements of existing tasks, there is no need to take the initiative to change.So there is a jargon in the industry that ldquo; may be the better enemy of the good & rdquo;, may make a big mistake.

Ldquo; unless the manned space project proposes mission adjustments to the Shenzhou spacecraft, the Shenzhou spacecraft will certainly make as few changes as possible so as to protect the safety of the astronauts from being threatened as much as possible. & rdquo

The chief designer of the manned spacecraft system of the Fifth Academy of Aerospace Science and Technology Group also said that if ldquo; has a new technology, no matter how advanced, fancy and gorgeous it is.Well, if its price is to reduce the reliability or safety of this manned spacecraft, then we must abandon it.。”
