Astronomers have long suspected that Mars once had oxygen in its atmosphere – it gets its name "The Red Planet" because the planet is essentially covered in rust, or iron oxide, which is made up of iron and oxygen. But the rocks studied by Spirit, which are much older than the meteorites that have landed on Earth, contain much more oxygen in them than the meteorites.
