Hugging the limestone?
1989/09/01 Elhuyar Zientzia Iturria: Elhuyar aldizkaria
Probably two meteorites of Martian origin have found calcium carbonate. Calcium carbonate is common on Earth, a substance that forms limestone. It is very important to find calcium carbonate in the stones of Mars. In fact, this compound is only generated in humid environments. The discovery can serve to demonstrate the existence of water last Tuesday, if it ensures that the planet is red at the origin of meteorites.
