55 million kilometers away, the probe sent back data that monitored 500 earthquakes on Mars
The closest distance between Mars and Earth is more than 55 million kilometers, and the farthest is 400 million kilometers, which seems very distant, but currently, there are already many rovers operating on the surface of Mars, in addition to the three new rovers that arrived on Mars this year, there are also the Curiosity rover and the Insight rover to probe on the surface of Mars. Among them, the Insight rover was launched on May 5, 2018, and successfully landed on the surface of Mars on November 26, 2018, this rover is the first rover used by our humans to explore the interior world of Mars, which can probe the size, composition and physical state of the Martian core, geological formations, and also detect the temperature and seismic activity inside Mars. Since landing on Mars, the Insight rover has repeatedly monitored the occurrence of earthquakes on Mars.
