Long March 7 Y3

The long March 7 remote three carrier rocket is the carrier rocket that carries out the launch mission of the Tianzhou II cargo spacecraft. In April 2021, the long March 7 remote three carrier rocket completed all the research and development work before it left the factory and arrived safely at the Wenchang Space launch site in Hainan. On May 16, the combination of the Tianzhou II cargo spacecraft and the long March 7 remote three carrier rocket was transferred to the launch area. At 20:55 on May 29, 2021, the long March 7 remote three carrier rocket carrying the Tianzhou 2 cargo spacecraft was ignited on time at the Wenchang Space launch site in China. About 604 seconds later, the spacecraft was successfully separated from the rocket and accurately entered the predetermined orbit. 21:17, the solar panels successfully carried out their work, and the launch was a complete success.
Don't make big moves when there is no separation at the first level
