These days, not so much. However, more than 4.5 billion years ago, it’s possible the Red Planet had a crust comparable to Iceland today. This discovery, hidden in the oldest Martian fragments found on our planet, could provide information about Earth that was lost over billions of years of geological movement. It could also help explain why the Earth developed into a planet that sustains a broad diversity of life, while Mars did not.
Designated Northwest Africa 7034, and nicknamed “Black Beauty,” the Martian meteorite weighs approximately 11 ounces . Credit: NASA , searched for the location of origin of a Martian meteorite . This meteorite, the chemistry of which indicates that Mars had volcanic activity to that found on Earth, recorded the first stage of Mars’ evolution. Although it was ejected from the surface of Mars five to 10 million years ago after an asteroid impact, its source region and geological context have remained a mystery.
Payré studies the nature and formation of Mars’ crust to determine if Earth and Mars share a common past that includes both a continent-like and ocean-like crust. She uses orbital observations captured in this region to investigate whether traces of volcanism similar to Iceland exist on Mars.
