NASA subjected its new Mars rover to harsh Mars-like environs
Nine months till blast-off.
NASA's latest car-sized, six-wheeled Mars rover, currently dubbed the 2020 Rover, is in the final stages of testing before launching to the red desert planet.
On Thursday, NASA released footage showing researchers transferring the rover into a vacuum testing chamber at the agency's Jet Propulsion Laboratory in Southern California. There, NASA subjected the rover to a simulation of Mars' frigid atmospheric conditions to ensure the rover's antennas, ground-penetrating radar, cameras, and equipment work under such extreme, extraterrestrial environs.

If all goes as planned — including a dramatic descent to the Martian surface requiring rockets and a supersonic parachute — the rover will settle into Mars' 1,640-foot-deep Jezero Crater in February 2021.
Planetary scientists suspect Jezero once held an 800-foot-deep lake some 3.5 billion years ago. This environment likely held nutrient-rich clay minerals that may have been an ideal place for Martian microbes to flourish, as they do in moist clays on Earth.
The rover will not only analyze the now-dry crater for past signs of primitive, microbial life, but also collect samples to be taken back to Earth at a later date.
"Getting samples from this lake-delta system will revolutionize how we think about Mars and its ability to harbor life,” Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate, said in 2018.
