NASA's probe Perseverance survived the Mars atmosphere and successfully landed on the surface. The landing sequence was an engineering masterpiece. At first, the probe free-fallen through the Mars atmosphere. Then, deployed parachutes to decelerate. When the spacecraft was close to the surface, it fired onboard thrusters to slow itself down and hovered above the ground. Then the Perseverance was lowered down on cables to the surface.
Now, when the rover is on Mars, it can start its primary mission:
- studying Mars' Habitability,
- seeking Signs of Past Microbial Life,
- collecting and Caching Samples,
- preparing for Future Human Missions.
Also, during this mission, NASA will test a drone called Mars Helicopter. If it works, it will be the first time we will be flying (not just falling) on Mars.
