Asteroids and meteorites that impact Mars bring seismic waves over the next planet. Researchers were able to record and study the recent seismic waves which emanated from Mars, and it is a unique discovery as there are no other planets that have this, other than the Earth.
It may be time to explore Mars as its map is now available for all. NASA brings a new advancement to its Martian study, and it is through the Mars Reconnaissance Orbiter (MRO) that delivered the first extensive map of Mars.
