Three Chinese astronauts returned to Earth on Monday after a six-month stay on China's Tiangong space station .
A parachute slowed their capsule's nighttime descent to a remote landing area in China's Inner Mongolia region. The crew emerged after touching down at 124 a.m. A Chinese national flag stuck in the ground near the capsule flapped in the wind.
The Tiangong space station, which was completed two years ago, is part of China's efforts to be a global leader in space exploration. In recent years, the country's space program has brought back rocks from the moon and landed a rover on Mars. It aims to put a person on the moon by 2030, which would make it the second nation after the United States to do so.
The space station astronauts returned after welcoming a replacement three-person crew last week for the latest six-month mission. The new crew will conduct experiments, carry out spacewalks and install equipment to protect the station from space debris.
A space agency official said in April that Tiangong has maneuvered several times to avoid debris and had partially lost power when the solar wing's power cables were hit by debris, according to a report from the official Xinhua News Agency.
