NASA’s Mars 2020 Rover Mission Unlisted Video

NASA plans to land on Mars again in 2020.
They plan on using a rover to look for signs of life and collect samples.
Recently, they have been undertaking a series of tests to prepare for the launch.
“ST1 was a massive undertaking. It was our first chance to exercise the flight software we will fly on 2020 with the actual spacecraft components that will be heading to Mars — and make sure they not only operate as expected, but also interact with each other as expected.” Heather Bottom, Systems Engineer for the Mars 2020 Mission
Their biggest challenge will be how the rover withstands low temperatures on Mars.
