NASA’s Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet.

The landing sites of all four Mars rovers on a map of Mars. The Opportunity rover investigated its own heat shield which impacted about 725 meters away and broke into two large pieces. NASA’s Opportunity Rover Dies on Mars By JONATHAN CORUM FEB. 13, 2019 Opportunity bounced to a stop on the Martian surface in 2004 and roamed from crater to crater for 14 years. The Mars Opportunity Rover has been working hard to find soils and rocks in an effort to find clues to any kind of past water activity in Mars. To do this, scientists sent the two rovers to two different landing sites. Spirit and Opportunity were sent to Mars to find more clues about the history of water there, and to see if the Red Planet could ever have supported life. (Episode 6) NASA’s Opportunity had just made the most important discovery of its mission, the rock vein known as Esperance. The rovers landed on opposite sides of the planet. NASA's Opportunity, the Mars rover that was built to operate just three months but kept going and going, was pronounced dead Wednesday, 15 years after it landed on the red planet. NASA is planning to use Opportunity for the next Martian Winter to perform research in order to find outcrops that feature clay minerals. One of the most successful and enduring feats of interplanetary exploration, NASA's Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet.
