Tianwen-1

TianWen-1

Tianwen-1 mission is the first mission to explore Mars in China, and China become the first nation to orbit, land, release a rover, and deploy smallsats during its first foray into Martian space. Tianwen-1 consisting of 3 parts: an orbiter, lander and the Zhurong rover. 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. For the next three months the probe studied the target landing sites from a reconnaissance orbit. On 15 May 2021, the lander/rover portion of the mission successfully touched down on Mars.

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. In order to complete the scientific task, it carries 13 scientific instruments, Moderate Resolution Imaging Camera, High Resolution Imaging Camera, Mars Orbiter Scientific Investigation Radar, Mars Mineralogical Spectrometer, Mars Orbiter Magnetometer, Mars Ion and Neutral Particle Analyzer, Mars Energetic Particles Analyzer onboard orbiter, and Navigation and Terrain Camera, Multispectral Camera, Mars Rover Penetrating Radar, Mars Surface Composition Detector, Mars Rover Magnetometer, Mars Climate Station onboard rover.
