Martian Meteorite Measurements Give Information on Planet Evolution Yale University

Scientists in the department of Geology and Geophysics at Yale University have devised a method to precisely date the timing and temperature of a meteorite impact on Mars that led to ejection of a piece of the planet into space and its eventual impact on Earth.
Meteorites are the main source of mass exchange between planets and carry with them characteristic clues about the nature and history of the planets or planetesimals where they originated, the impacts that dislodged them, and the time they spent in space.
Kyoungwon Kyle Min, postdoctoral fellow in geology, reported an innovation for determining the timing and temperatures of ancient impacts that liberate meteorites from extraterrestrial bodies such as Mars.
