In less than an hour, the Shenzhou 14 manned spacecraft will be launched soon. The Shenzhou 14 manned mission is the second and first manned mission in the construction phase of the space station. The astronauts will work and live in orbit for six months. The main purpose of this mission is to complete the on orbit assembly and construction of the Chinese space station by cooperating with the rendezvous, docking and transposition of the Wentian experimental module, the Mengtian experimental module and the core module; Complete the installation and commissioning of equipment inside and outside the space station and relevant facilities and equipment for space application tasks; Carry out space science experiments and technical experiments; Carry out daily maintenance and repair. Due to the heavy task and tight time, the shenshishi group is also known as the "busiest trio". It is reported that the three astronauts will spend the national day and the Mid Autumn Festival in space for the first time. To this end, the space system has prepared special festival food for the astronauts for the Mid Autumn Festival, small items to decorate the Mid Autumn Festival and National Day holiday atmosphere, as well as blind boxes that will bring them some small surprises. At the same time, it will also arrange the astronauts to spend time with their families by telephone through heaven and earth connection. However, from the time arrangement of the mission, it is likely that the three astronauts will celebrate the two festivals as labor day, because the Mid Autumn Festival overlaps with the time node for preparing the second mission, which should be very busy at this time.
