After 4 minutes of atmospheric braking at a height of about 12 km, the 11.88 m (39 feet) canopy was opened, followed by the separation of the body's heat shield from the vehicle.
NASA said the vehicle had released the stents before the total landing of 15 seconds, and that the vehicle speed during this stage was 8 km / h thanks to the brake motors, before touching the surface of the planet.
The probe is supposed to probe the surface of the red planet and to install SEIS to measure the seismic movement and the movement of the rocks in the interior of the planet. The agency said the device would be the first in 40 years to listen to the pulse of the red planet as a stethoscope does.
