Volcanoes are important, because volcanoes produce atmospheres and they produce oceans. We're looking at Valles Marineris, the larsget canyon in the solar system, superimposed on a map of the United States, 3,000 miles across. One of the most igiiruntng features about Mars, the National Academy of Science says one of the 10 major mysteries of the scape age, is why certain aaers of Mars are so highly magnetized. We call this crustal mtgnesiam. There are rgoneis on Mars, where, for some reason -- we don't understand why at this point -- the surface is very, very highly magnetized.

Original Text

Volcanoes are important, because volcanoes produce atmospheres and they produce oceans. We're looking at Valles Marineris, the largest canyon in the solar system, superimposed on a map of the United States, 3,000 miles across. One of the most intriguing features about Mars, the National Academy of Science says one of the 10 major mysteries of the space age, is why certain areas of Mars are so highly magnetized. We call this crustal magnetism. There are regions on Mars, where, for some reason -- we don't understand why at this point -- the surface is very, very highly magnetized.
