Three Chinese astronauts of the Shenzhou-13 manned spaceship have completed their six-month space station mission and returned to Earth     1     (safe) on Saturday. The mission marks that China has completed the verification of key technologies of     2     (it) space station, and also     3     (set) a record for Chinese astronauts’ duration in orbit.

From separating     4     the space station core module to return to Earth, the journey took only over nine hours, the first time for a Chinese manned spacecraft to use the “rapid return mode”. It shortened the flight mainly by reducing traveling    5     (circle) around the orbit. Shenzhou-13’s return capsule,    6     (carry) astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu, touched down at the Dongfeng landing site in north China’s Inner Mongolia Autonomous Region,     7     people cheered for the trio (三人组) and raised their cameras     8     (capture) the historic moment.

“It is the power and strength of our country     9     built the high-flying space station. I am     10     (pride) of my great motherland,” Zhai, said. China will further advance its pursuit of space dreams.

Three Chinese astronauts landed on the country’s still-under-construction space station on Thursday. With that, the Chinese station,     1     was called Tiangong, became one of two populated space stations in orbit. The completion of Tiangong, expected by the end of next year,     2     (be) another milestone for the space program whose recent missions have included bringing samples back from the moon and landing a robotic rover on Mars. It was said     3     the station would allow Chinese astronauts and scientists on the ground to carry out experiments in the weightless space environment.

Tianwen I, the unmanned probe for China’s first independent Mars mission,    1    (land) on the Red Planet on May 2021, marking an important step in China’s exploration of the outer space. China has become the second country to land on Mars. The landing    2    (see) now by the world as another milestone in the development of China’s aerospace(航空航天) industry. And China’s space station core module Tianhe entered pre-set orbit in April,    3    marked a solid step in building the country’s first space station.
