 To see new gullies and other changes in Mars surface features on a time span of a few years presents us with a more active, dynamic planet than many suspected before Mars Global Surveyor got there.

 To see new gullies and other changes in Mars surface features on a time span of a few years presents us with a more active, dynamic planet than many suspected.

 What the Mars orbital camera has revealed from this long and detailed study of the Red Planet is a dynamic Mars, a planet that can change – not on the mind-boggling millions and billions of years, but on the order of years and decades.

 If liquid water pops out onto Mars' surface, it can create short gullies about 550-yards (500-meters) long. We find that the short length of the gully features implies they did form under conditions similar to those on present-day Mars, with simultaneous freezing and rapid evaporation of nearly pure liquid water.

 Dramatic discoveries ... about recent gullies, near-surface permafrost and ancient surface water have given us a new Mars in the past few years.

 Mars is an active planet, and over a range of timescales changes occur, even in the surface.

 These images describe a dynamic surface of the planet Mars. They catch Martian geology in action.

 The missions currently at Mars have each advanced what we know about the presence and history of water on Mars, and one of the main goals for Mars Reconnaissance Orbiter is to decipher when water was on the surface and where it is now.

 If we find evidence that (those) minerals are there, there must have been a time in Mars' early history when there was standing water on Mars' surface.

 These are new landforms that have never been seen before on Mars, ... We see features that look like gullies formed by flowing water and the deposits of soil and rocks transported by these flows.

 These are new landforms that have never been seen before on Mars. We see features that look like gullies formed by flowing water and the deposits of soil and rocks transported by these flows.

 Mars is the most habitable planet accessible to us. It's not extremely cold or hot. It's possible to imagine human colonies on Mars.

 The first boots on Mars will probably get dusty at one of the many potential landing sites the Mars Reconnaissance Orbiter will inspect all over the planet.
