Scientists used to consider Mars a geologically dead planet. It's smaller than Earth and loses internal heat faster. In the past, there was a lot of activity in its depths, and there are many traces of huge volcano eruptions on its surface. The largest volcano in the Solar System, Olympus, can be seen from Earth even with an amateur telescope. But volcano eruptions on Mars stopped a long time ago. The planet's interior cooled and solidified, the internal cooling weakened its magnetic field, the

Most Martian rocks are volcanic, showing that Mars was once a very active planet with flowing lava and massive eruptions, including the formation of huge volcanoes like Olympus Mons. #Mars #MarsMystery #marsrover #exploration #NASA #fblifestyle | Mars journey
