Winning Terrain at Home Plate
September 22, 2007
After waiting out a long, cold winter and a global dust storm, Spirit finally has enough power to explore Home Plate the way scientists have been longing to do since they first saw the layered terrain. Why all the excitement? If you were going to look for past water on Mars, there are three good ways: 1) Look for salts left behind from salty water that evaporated; 2) Look for rocks that show evidence of being originally laid down wet; and, 3) look for signs of volcanic explosions where water contacted hot, molten rock. At "Home Plate" on Mars, scientists have found all three. That's certainly a home run in the search for more clues to the history of water on Mars.
