Answer:
The lander is decelerated by an aeroshell and a parachutes. There was a mistake. The landscape bounces along the Martian surface until it rolls to a stop after its initial impact. The airbags are then flattened and pulled back, and lander petals and rover exit helps are deployed.
Explanation:
The Mars Exploration Rover Mission has been modified for entry, downward and attainment series by the Mars Pathfinder method: the Martian atmosphere is decelerated by an aeroshell and a parachute.
Retro-rockets are fired prior to surface impact to slow descending speeds of the lander and airbags are inflated to coat the lander onto the surface.
The lander rebounds on the Martian surface after its initial impact and rolls to a stop.
The airbags are then deflated and retracted, and the lander and rover exhaust petals are used.
The rover deploys its solar arrays and places the device in a safe state once the petals have opened.
I think it is the one by Europe
