We can do things that rovers can't do and landers can't do: We can fly above mountains, volcanoes, impact craters; we fly over valleys; we can fly over surface magnetism, the polar caps, subsurface water; and we can search for life on Mars.
Možemo raditi ono što niti roveri niti landeri ne mogu: Možemo letjeti iznad planina, vulkana, udarnih kratera; letimo iznad dolina; možemo letjeti iznad površinskog magnetizma, polarnih kapa, vode pod površinom; i možemo tražiti život na Marsu.
