How two new technologies will help Perseverance, NASA’s most sophisticated rover yet, touch down onto the surface of Mars this month.
PASADENA, Calif. (NASA PR) — After a nearly seven-month journey to Mars, NASA’s Perseverance rover is slated to land at the Red Planet’s Jezero Crater Feb. 18, 2021, a rugged expanse chosen for its scientific research and sample collection possibilities.
Terrain-Relative Navigation (TRN) technology from NASA’s Jet Propulsion Laboratory (JPL) enables pin-point landing and large hazard avoidance for crewed and robotic lander vehicles. A camera captures images during vehicle descent, which are subsequently matched to orbital maps stored onboard the lander. Matching images to multiple known terrain features enables automated determination of the lander’s position relative to the terrain.
