NASA's Perseverance rover landed in Jezero Crater on February 18, 2021, after years of design work this film tracks in detail, from wind tunnel tests to the tense final descent. Engineers and mission scientists explain why Jezero, believed to be a dried river delta, was chosen as the landing site and what geological biosignatures they hope its rock samples might hold. The documentary follows the rover's instruments as they begin drilling and caching samples destined for eventual return to Earth, and covers the accompanying mini-helicopter Ingenuity's first test flights, the first powered flights ever attempted on another planet. It also details Perseverance's experimental MOXIE instrument, designed to extract oxygen from the thin Martian atmosphere as a step toward future crewed missions. Archival development footage, mission control interviews, and high-resolution images beamed back from the surface trace the mission from a risky engineering gamble to a working outpost on another planet, with the search for past life running through the whole story as the driving question.
