On May 29, China successfully launched the Tianzhou-2 cargo spacecraft with the Long March 7 Yaosan rocket at the Wenchang Space Launch Site.
The space station's Tianhe core module ushered in the first "visitor".
The Tianzhou-2 cargo spacecraft launched this time was developed by the Fifth Academy of China Aerospace Science and Technology Corporation and is the first spacecraft in the construction phase of the space station project.
This mission will realize the rendezvous and docking of the cargo spacecraft and the space station's core module for the first time, transporting the daily necessities needed by the astronauts on the space station, the materials for conducting space science experiments, and the propellant used to supplement the space station's core module.
According to Feng Yong, the commander-in-chief of the Tianzhou-2 cargo spacecraft of the Fifth Academy of China Aerospace Science and Technology Corporation, Tianzhou-2 adopts a two-cabin configuration and is composed of a fully sealed cargo compartment and a propulsion compartment. The total length is 10.6 meters, the maximum diameter is 3.35 meters, and the largest The take-off weight is 13.5 tons, the material upgoing capacity is 6.9 tons, the cargo ratio is 0.51, the on-orbit life is not less than 1 year, and the power supply capacity is not less than 2700 watts; it has all-phase autonomous rendezvous and docking capabilities, and can complete propellant replenishment multiple times .
