NASA Showcases Its New Mars Rover, Calls It Precursor to Humans on Mars

"The Mars 2020 rover, which sets off for the Red Planet next year, will not only search for traces of ancient life, but pave the way for future human missions, NASA scientists said Friday as they unveiled the vehicle." An anonymous reader quotes Agence France-Presse:The rover has been constructed in a large, sterile room at the Jet Propulsion Laboratory in Pasadena, near Los Angeles, where its driving equipment was given its first successful test last week. Shown to invited journalists on Friday, it is scheduled to leave Earth in July 2020 from Florida's Cape Canaveral, becoming the fifth U.S. rover to land on Mars seven months later in February [of 2021]. "It's designed to seek the signs of life, so we're carrying a number of different instruments that will help us understand the geological and chemical context on the surface of Mars," deputy mission leader Matt Wallace told AFP. Among the devices on board the rover are 23 cameras, two "ears" that will allow it to listen to Martian winds, and lasers used for chemical analysis... Fuelled by a miniature nuclear reactor, Mars 2020 has seven-foot-long (two metre) articulated arms and a drill to crack open rock samples in locations scientists identify as potentially suitable for life. "What we're looking for is ancient microbial life -- we're talking about billions of years ago on Mars, when the planet was much more Earth-like," said Wallace... The Mars 2020 mission also carries hopes for an even more ambitious target -- a human mission to Mars. "I think of it, really, as the first human precursor mission to Mars," said Wallace. Equipment on board "will allow us to make oxygen" that could one day be used both for humans to breathe, and to fuel the departure from Mars "for the return trip." NASA has uploaded footage of the rover's first test drive.
