After N.A.S.A.'s Mars Reconnaissance Orbiter discovered pictures of a valley on Mars, scientists are beginning to question whether or not there is water as a trace that there is or was life Mars. There were layers of dark and light rock which filled a giant rift valley. Some say that there were areas in which water passed through the bedrock. Researchers say that layered outcrops can indicate signs of cycles of water, wind, or volcanic acid once passing through. Last December there was evidence of water possibly passing through. More recent photos show changes in craters which could mean that there was water passing through only a few years ago, or possibly even now.
I was interested in this article because if there is still water passing through Mars than possibly in a couple hundred years or so we could start human life on Mars. Also, maybe people could go to Mars temporarily to tour the planet with less risk considering there could be water. Not only could we send humans there but, also, if there was life there, then maybe it could come to Earth.
