Despite satellite images that show vast networks of channels,
past Mars rover missions have shown limited evidence for flowing water
on Mars. Now, rocks analyzed by NASA’s Mars Curiosity Rover team,
including Linda Kah, associate [...]
A chemical reaction between iron-containing minerals and water
may produce enough hydrogen “food” to sustain microbial communities
living in pores and cracks within the enormous volume of rock below the
