"The installation of outboard loads is a new task. For the astronauts, they have to conduct extravehicular tasks at the time when the space station has its largest ever configuration. For example, the astronauts working on the bulkhead have to move a long distance from one end of the space station to the other. Meanwhile, in order to improve efficiency, we need two astronauts to carry out extravehicular operations in parallel at two points. So, there are very strict requirement on each of the three astronauts to complete the operation independently. They will face greater challenges."

The three astronauts of the Shenzhou-15 space mission will accomplish a host of tough tasks during their six-month stay in China's space station complex, said Huang Weifen, chief designer of the astronaut system under China's manned space program.

Currently, the T-shaped configuration of China's space station is composed of the Tianhe core module, the Wentian lab module and the Mengtian lab module. As the basic configuration is completed, the space station becomes more spacious and comfortable for astronauts to stay, but at the same time, the more complicated configuration has brought more workload and challenges for the three astronauts of the Shenzhou-15 mission.

"During their in-orbit stay, the space station has the largest configuration of three modules. The operation and maintenance of three modules is quite huge a workload, which is more than that of single-module or two-module structure," said Huang.

In addition to routine maintenance of the space station, the three astronauts of the Shenzhou-15 mission will also complete a large number of experiments with the 24 experimental cabinets onboard the space station, including some concerning aerospace medicine.

In addition, during the six-month mission in space, the astronauts have to complete three to four extravehicular missions, some of which had never been conducted before.

"The installation of outboard loads is a new task. For the astronauts, they have to conduct extravehicular tasks at the time when the space station has its largest ever configuration. For example, the astronauts working on the bulkhead have to move a long distance from one end of the space station to the other. Meanwhile, in order to improve efficiency, we need two astronauts to carry out extravehicular operations in parallel at two points. So, there are very strict requirements on each of the three astronauts to complete the operation independently. They will face greater challenges," said Huang.

The Shenzhou-15 crewed spaceship is scheduled to launch at 23:08 Tuesday (Beijing Time) at the Jiuquan Satellite Launch Center in northwest China.

Carrying three astronauts, this is the sixth flight mission of China's manned spaceflight program this year and the last one in the key construction phase of China's Tiangong space station.
