Hey Space Placers!
NASA held a news conference yesterday (8-4-11) to announce findings that Mars most probably has flowing liquid salt water. The findings are based on study of photographs taken by Mars Reconnaissance Oribter (MRO). The photos show dark "fingers" running down the sides of steep slopes in the Martian spring and summer. Scientists can think of no other probable reason for this to occur.
See a movie showing these dark fingers and read more about it:
