A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020, 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [1]

Are there meteorites on Mars?
A meteorite that lands on Earth's surface would rust away in a blink of geologic time. Mars, however, has very little oxygen and moisture in its atmosphere and surface soils. Meteorites that land on Mars can remain in excellent condition for millions - or even billions - of years. Mars is the perfect place for hunting meteorites.
Dec 18, 2014 · NASA. Dec 18, 2014. RELEASE 14-337. NASA and an international team of planetary scientists have found evidence in meteorites on Earth that indicates Mars has a distinct and global reservoir of water or ice near its surface. Though controversy still surrounds the origin, abundance and history of water on Mars, this discovery helps resolve the ...
Nov 20, 2020 · Currently, samples from Mars are obtained as meteorites that have been ejected from the planet. We can study these rocks to learn about volcanic processes and their chemistry and timing in the context of martian geology. This review paper summarizes the information we have learned about Mars's geology by analyzing martian meteorites.
Sep 19, 2022 · Researchers have puzzled over why they haven’t detected more meteoroid impacts on Mars. The Red Planet is next to the solar system’s main asteroid belt, which provides an ample supply of space rocks to scar the planet’s surface. Because Mars’ atmosphere is just 1% as thick as Earth’s, more meteoroids pass through it without ...
