China’s Tianwen-1 Mars probe just completed its number one goal

Posted by in category: space

Tianwen-1 is a historic victory for both the CNSA and space exploration.

Upon successful orbital insertion and landing, Tianwen-1 became a historic victory for the CNSA and space exploration. Before Tianwen-1, the only two successful missions to send an orbiter and lander to Mars were NASA’s Viking 1 and 2 missions in 1975. Prior to that, the Soviet Union had attempted this feat with their Mars 2 and 3 missions in 1971 and Mars 6 in 1973.

Mars 2 was an outright failure, with the lander being destroyed and the orbiter sending back no data. On Mars 3, the orbiter obtained approximately eight months of data, and while the lander touched down safely, it only returned 20 seconds of data. On Mars 6, the orbiter produced data from an occultation experiment, but the lander failed on the descent.
