The Mars 2020 mission involves sending a rover, named Perseverance, to Mars to look for evidence of past life on that planet. Perseverance will collect samples of 3 billion year old rocks that scientists on Earth think might contain signs of ancient life on Mars. Later, NASA will launch a mission to retrieve those…
