The Mars rover launched from the Cape Canaveral Space Force Station in Florida, back on July 30 2020.
The plan was to use the rover to collect Mars samples, and then return them to Earth.
Perseverance will investigate the rock and sediment of Jezero’s former lakebed and river delta.
But, another key part of the mission was to research astrobiology.
Scientists will be using the samples to search for signs of ancient microbial life, which will provide definitive proof that life once existed on the Red Planet.
