Tianwen-1
Tianwen-1 (TW-1; simplified Chinese: 天问; traditional Chinese: 天問; literally "heavenly questions") is a space mission by the China National Space Administration (CNSA) to send a robotic spacecraft to Mars. It carries an orbiter, deployable camera, lander and rover.
The mission was successfully launched from the Wenchang Spacecraft Launch Site on 23 July 2020[1] on a Long March 5 heavy-lift launch vehicle and is currently in orbit around Mars, having reached planetary orbit on 10 February 2021.[2][3]
On 14 May 2021, the rover landed on Mars, making China the fourth country to land a spacecraft on the planet and only the second to land a rover.[4][5]
