At present, the crew of Shenzhou-15 astronauts has been in orbit for five months, and all work is steadily progressing, while fully preparing for the upcoming Tianzhou-6. April 30th is the day when astronauts Fei Junlong, Deng Qingming, and Zhang Lu of Shenzhou XV have been in orbit for five months. After five busy months, the workload of the three astronauts during the Labor Day holiday has correspondingly decreased. According to the plan, they will mainly complete some environmental control and life support maintenance work for the space station in the coming days, and continue to support the various space experiments and experiments currently underway. In addition, the three astronauts will also arrange physical training and other activities according to their own situation. In order to welcome the arrival of Tianzhou-6, the Shenshiwu crew has also been sorting out the remaining cargo on Tianzhou-5 in recent days. Some of the cargo will be left at the space station, and the remaining consumables will be placed inside Tianzhou-5 after sorting out, so that it can be burned and destroyed when it re-enters the atmosphere. At present, Tianzhou-5 is located at the backward interface of the space station assembly, and it is planned to separate from the space station in the near future to make way for the upcoming Tianzhou-6 interface. The Tianzhou-6 cargo spacecraft and the Long March 7 rocket have been tested at the Wenchang Space Launch Site in Hainan, and preparations for the launch site have been carried out in an orderly manner.
