Artwork of NASA's Mars 2020 mission. The mission consists of a 3-metre-long rover called
Perseverance, and a smaller 'rotorcraft' (1.2 metres in diameter, not shown here) called Ingenuity.
The helicopter is expected to fly five missions during the first 30 days of the mission, scouting
locations for the rover. It is the first attempt at flight on another planet. The rover, meanwhile,
will search for past signs of life in the red Martian soil, limiting its search to the bed of an
ancient lake (now a crater called Jezero) and will prepare samples left on the planet's surface for
later recovery and analysis on Earth. The rover is seen against a Martian Sunset.
