NASA has revealed details of how it is planning to bring samples from Mars to Earth. According to an update posted on the space agency's website, the compact, lightweight Mars Ascent Vehicle (MAV) will be used for launching rock, sediment, and air samples from the surface of Mars. The award for its construction has been awarded to Lockheed Martin Space, of Littleton, Colorado. This move takes the Mars Sample Return Program's goal of making the first robotic round trip to safely return samples to Earth one step closer to success.
