Four days after the landing of Perseverance, NASA shared a spectacular unpublished video with four cameras that captured its entry into the atmosphere and arrival on Martian soil.
In an unprecedented event, NASA shared the first video of the history of a landing on Mars. The 3 minutes and 25 seconds long material is part of the recordings made by four cameras different during the riskiest phase of the mission, the moment of entry, descent and landing (EDL) from Perseverance on the Red Planet.
The video was made with a camera included in the descent stage, a camera integrated in Perseverance that pointed up in the last meters before landing, another camera on the top of the rover and another, located on the bottom of the vehicle robotic that faces the Martian soil, capturing the final soft landing:
The video starts at approximately 9 thousand meters highseconds after the deployment of Perseverance’s supersonic parachute, which was then plunging to the Martian soil at a speed of 1,152 kilometers per hour.
Around 0:33 second, another camera included in Perseverance pointing towards the ground shows the detachment of heat shield that protected the rover during its entry into the atmosphere.
For the next minute, the camera follows the vision of the Terrain-Relative Navigation (TRN) system, which performed the necessary calculations to correct the last orientation prior to landing. In this phase, craters with reddish tones and some elevations of the red planet.
At minute 2:35, Perseverance begins its penultimate phase of descent at 300 meters high and at approximately 2 minutes and 50 seconds, three simultaneous cameras capture the crane maneuver, which separates the rover from the thrusters and nylon ropes that ensured a smooth touchdown in the Martian sand.
The peak landing moment occurs at 3:09, when Perseverance touches the surface of the Jezero crater and instantly, the last stage with the thrusters and ropes is suspended to land in another safe place.
The audio that accompanies the video is composed of the commands that were heard in the NASA Control Center during the last three and a half minutes of the maneuver.
