The question of how Mars changed from a once wet world to the much colder and drier one we see today is one that scientists have been trying to answer for a long time. There is plenty of evidence that Mars use to have lakes and rivers, and perhaps even oceans. But what happened to change that? Now, a new study might bring us one step closer to solving this conundrum.
Only a couple of weeks after India launched its first-ever mission to Mars, NASA has also just sent another probe to the Red Planet. The Mars Atmosphere and Volatile Evolution Mission (MAVEN) spacecraft was successfully launched yesterday, November 18th, at 1:28 pm EST from Cape Canaveral Air Force Station in Florida.
