If all goes well, the autonomous plane takes a snapshot of the aerial photos of Mars cliffs, caves, and craters that the land-based rover can not explore. And even if it does not take a flight, the rover can collect important data from the surface.
NASA hopes the helicopter will eventually carry tools around the planet and guide astronauts on their arrival.
The rover starts in July 2020 and will not arrive until 18 February 2021 in the Jezero Crater. However, when the helicopter flies up, it offers an unprecedented view of the Red Planet.
