China and Mars Mission Tianwen-1

China successfully landed its rover on Mars on May 14, 2021. After landing, it took 17 minutes to unfold the solar panels attached to this system and send a signal back to Earth. It may be noted that the current distance to Mars from the Earth is 320 million km, and it takes about 17/18 minutes for radio messages to reach Earth. Presently, this rover is situated inside a lander and would take few more days to get out of the lander's belly and start moving on the Martian surface. It is expected to operate for three months.
