NASA's Martian rover has found some intriguing stuff in the soil and rock that it has dug up. The soil contains lots of sulfur and traces of water. "This material could have been left behind by water that dissolved these minerals underground, then came to the surface and evaporated, or it could be a volcanic deposit formed around ancient gas vents," said Dr. Ray Arvidson. it should be interesting for the scientists to find out which one of these ideas is correct. The soil was dug up when Spirit was trying to cross a soft part of soil with one bad wheel.
