Absolutely Astonishing
The fact the this much equipment can be packed into a spaceship and blasted off from Earth to Mars, about 50 million miles away, is amazing enough in its own right. Then consider that due to the limitation of the speed of light, it takes about 1/2 an hour to send a command and receive an answer in order to control the equipment. Then consider that they are trying to map out the geological history of an entire planet. It almost makes me think that actually sending humans there will almost be a letdown compared to - THIS.

Was Mars the first to experience global warming?
Getting the answer to the question of what happened to Mars' atmosphere is key to narrowing the search for more earth-like planets in the galaxy. Mars probably falls into what is considered the inhabitable zone in relation to its star, but that zone may be too broadly defined if being as close as Mars causes all your liquid water to disappear. Or perhaps Mars went through its own form of global warming, which destroyed its ability to sustain the presence of liquid water. The traces of the seas once on Mars are unmistakeable.
