Summary
| Description |
English: An illustration of NASA's Perseverance rover landing safely on Mars. The actual landing occurred on 18 February 2021.
Entry, Descent, and Landing, or "EDL," begins when the spacecraft reaches the top of the Martian atmosphere, travelling nearly 12,500 mph (20,000 kph). EDL ends about seven minutes after atmospheric entry, with Perseverance stationary on the Martian surface. At about 6,900 feet (2,100 meters) above the surface, the rover separates from the backshell, and fires up the descent stage engines. As the descent stage levels out and slows to its final descent speed of about 1.7 mph (2.7 kph), it initiates the “skycrane” maneuver. About 12 seconds before touchdown, roughly 66 feet (20 meters) above the surface, the descent stage lowers the rover on a set of cables about 21 feet (6.4 meters) long. The rover unstows its mobility system, locking its legs and wheels into landing position. As soon as the rover senses that its wheels have touched the ground, it cuts the cables connecting it to the descent stage. This frees the descent stage to fly off to make its own uncontrolled landing on the surface, a safe distance away from Perseverance. |
