The surface of Mars is lined with mysterious deep-carved trenches. A long-standing theory suggesting that the were left long ago by flowing rivers was just debunked. So where did these trenches come from?
The Curiosity rover was sent up to Mars with the important job of hunting for microbes on the red planet’s surface. Now, that job is done, and Curiosity is getting a new mission—and that mission is all about the past, and future, of life on Mars.
Today we learned something new, and amazing, about Mars. But, although today was the day that the news was confirmed, it’s been in the making for quite sometime. Here, in pictures, is a history of how we finally found out that there really was water flowing up on Mars.
NASA just confirmed something incredible: There’s water flowing on Mars today. But what does that mean for life on the red planet today—both the life that may already be present, as well as the life we could bring by building a colony there?
Evidence suggests that Mars had water flowing on its surface at various points in its ancient history. But the evidence also points to temperatures being far too cold at those time for water to be liquid. So, how can both facts be true? At last, this paradox may be on the verge of resolution.
Scientists at JPL say that new analysis of pictures taken on Mars contains the "strongest indication" that there is water flowing on the red planet, right now.
NASA has yet to find liquid water on Mars, but analysis of the soil where the Spirit Rover became stuck last year suggests liquid water flowed through the soil — and fairly recently.
