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 [update] , 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [1]

Nov 20, 2020 · Although martian meteorites found in Antarctica have terrestrial ages and two orders of magnitude older than NWA meteorites (mean age of 30 ka), the latter are more weathered than the cold desert rocks, due to ice limiting interaction with liquid water (Sharp et al., 2019). Chemical alterations are more problematic for analyses.

Key Points. Martian meteorites are currently the only samples that we possess from the Red Planet. Martian meteorites reveal the compositional diversity of the interior of Mars. Returned samples from Mars would allow us to better constrain the compositions of the martian interior and its evolution through time.
