Landing safely on Mars is said to be one of the most challenging parts of any mission, even though the planet's gravitational pull is only about a third of that of Earth's.
Perseverance is the name of NASA's Mars 2020 rover that's scheduled to launch this summer and Ingenuity is the name of the drone helicopter it will be carrying.
Among the new features on this rover a terrain relative navigation, if you see that sort of red triangle, a camera in there is going to be taking images of Mars as it parachutes down into a crater.
