Chinese astronauts Cai Xuzhe and Song Lindong made the third spacewalk as part of the Shenzhou-19 mission, by installing the last protective shields against space debris at the Tiangong Orbital Station.
The last spacewalk of the "Shenzhou-19" mission.
21 In March, the crew of the "Tiangong" station completed a seven-hour off-board activity (EVA), which became the third spacewalk during their six-month stay in orbit.
- The exit has begun 05:45 UTC, when Cai Xuzhe opened the hatch of the Wentian module.
- O 12:50 UTC, both astronauts successfully returned to the station.
- Van Haocze, the first Chinese female engineer in space, supported the operation from within the station.
Installation of protection and verification of equipment.
The main task of the astronauts was to install the final protective screen against space debris on the Wentian module. This concluded a series of missions to strengthen the security of the orbital station.
in addition, astronauts:
- Additional equipment for off-ship activities was installed.
- Checked the status of the station's external systems - Cai Xuzhe used the station's robotic arm for a photo inspection.
This mission became a record for Cai Xuzhe - he made five spacewalks, more than any other Chinese astronaut.
Scientific experiments on board the station.
Over the past five months, the crew has conducted a series of scientific experiments and technological tests, Among them:
- Study of life in microgravity conditions - rearing fruit fly larvae, crystallization of proteins, study of the five types of cells.
- Materials science experiments – tests of metals and non-metals in a high-temperature environment without containers.
- Medical research - creation of a new system for monitoring the health of astronauts, which combines traditional Chinese and Western medicine.
- These studies make it possible to compare the conditions of experiments on "Tiangun" with results on International space station (ISS), contributing to joint development of space science.
