  • Trapped Rover Finds Evidence of Water on Mars
    Although NASA's Mars Exploration Rover Spirit is stuck in the soil of Mars, the rover is still gathering important data. The ground around Spirit holds evidence that water trickled into the subsurface fairly recently. The findings could have implications in the search for past or
