Nearly 200 Meteorites From Mars Have Been Discovered On Earth Researchers have performed numerical simulations to explore the launch mechanism of Martian meteorites. According to the knowledge of shock physics, a strong shock compression higher than 50 GPa is required to accelerate Martian materials up to the escape velocity of Mars (5 km/s). In contrast, detailed analysis of Martian meteorites shows that they suffer only 30-50 GPa during the ejection.
