• Resumen

  • Most meteorites from the Red Planet could be from the same crater, which would make them billions of years older than believed. About 80% of meteorites that have fallen to Earth from Mars belong to a group called the shergottites. Looking at the way minerals melted and reformed in these rocks, previous studies said that shergottites are 600 million years old at most. But Stephanie Werner at the University of Oslo in Norway and her colleagues now say that the rocks have all come from the same place, Mojave crater on Mars, which would make them 4.3 billion years old.
