One day spacecraft ship is China’s first cargo spacecraft. On the evening of April 20, 2017, the successful launch of the day boat was completed. At noon April 22, the spacecraft No. 1 on the day boat and the space laboratory on the second floor of Tian Temple successfully completed the rendezvous and docking. On the evening of April 27, Successfully completed the first trial of propellant on-orbit with Tiangong 2, marking a complete success of the day boat flight Zhouzhou. One of the most important tasks for the spacecraft One day spacecraft is to supplement the propellant, commonly known as “space refueling.” Its success, breakthrough and verification of the space station cargo transport, propellant on-orbit additional key technologies to fill China’s aerospace field
