The Mars Reconnaisance Orbiter has found evidence that suggests salty streams of seasonal water flow on the surface of Mars.
The NYT reports:
High-resolution photographs taken by NASA’s Mars Reconnaissance Orbiter, which arrived at Mars in 2006, show fingerlike streaks up to five yards wide that appear on some steep slopes in the late Martian spring. These streaks grow and shift through summer as temperatures warm, reaching hundreds of yards in length before they fade in winter. One crater had about 1,000 streaks.
But finding streaks is not the same as finding actual water. An instrument on the Mars orbiter capable of detecting water has not, in fact, found any, but that may just mean that the amount of water in the flows is too little to be seen from orbit.
