Tianwen 1

Tianwen-1 is an interplanetary mission by the China National Space Administration to send a robotic spacecraft to Mars, consisting of 5 parts: an orbiter, deployable camera, lander, drop camera, and the Zhurong rover. The spacecraft, with a total mass of nearly five tons, is one of the heaviest probes launched to Mars and carries 13 scientific instruments. It is the first in a series of planned missions undertaken by CNSA as part of its Planetary Exploration of China program. The mission's scientific objectives include: investigation of Martian surface geology and internal structure, search for indications of current and past presence of water, and characterization of the space environment and the atmosphere of Mars. The mission was launched from the Wenchang Spacecraft Launch Site on 23 July 2020 on a Long March 5 heavy-lift launch vehicle. After seven months of transit through the inner Solar System, the spacecraft entered Martian orbit on 10 February 2021.
