Researchers have identified the specific locations from which most of the approximately 200 Martian meteorites originate. They’ve traced the meteorites to five impact craters within two volcanic regions on the red planet called Tharsis and Elysium. Their study was published recently in the journal Science Advances.

Martian meteorites find their way to Earth when something hits the surface of Mars hard enough so that material is “blasted off the surface and accelerated fast enough to leave Mars’ gravity,” says Chris Herd, curator of the U of A’s Meteorite Collection and professor in the Faculty of Science...

Earth and Mars were formed from material that largely originated in the inner solar system; only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. A group of researchers led by the University of Münster (Germany) report these findings today in the journal Science Advances...

Researchers probed Martian meteorites to reconstruct Mars’ chaotic history. Their findings suggest that Mars might not have had a global magma ocean.

In Jessica Barnes’ palm is an ancient, coin-sized mosaic of glass, minerals and rocks as thick as a strand of wool fiber. It is a slice of Martian meteorite, known as Northwest Africa 7034 or Black Beauty, that was formed when a huge impact cemented together various pieces of Martian crust.
