Perseverance rover has sent back stunning video and audio from Mars

NASA’s Perseverance rover has despatched again astonishing video footage of its 18 February landing on Mars. These movies give us probably the most intimate look ever on the strategy of setting a spacecraft down on the Martian floor.

In the course of the touchdown, 5 cameras took movies: two on the again of the capsule holding the rover, one on the sky crane that acted as a jet pack to decrease the rover its remaining 2000 metres or so to the floor and two on the rover itself.

The movies present the parachute opening to decelerate the spacecraft, after which the warmth defend dropping to the floor of Mars as soon as Perseverance is shifting sluggish sufficient to not want it anymore.

“You may get a way actually of how violent that parachute deploy and inflation are,” stated Al Chen, a Perseverance engineer at NASA’s Jet Propulsion Laboratory (JPL) in California, throughout a press convention. “The parachute is packed so densely that the pack is mainly the identical density as oak, and it’s about 150 kilos. It will get launched out of the spacecraft with a mortar, which is mainly a cannon, with a muzzle velocity of round 100 miles per hour.”

The footage then shows the ground as Perseverance hurtles in direction of it. Lastly, totally different digicam angles present each the rover and the sky crane reducing it to the floor, in addition to wind from the crane’s thrusters blowing up mud through the remaining phases of the touchdown. The rover touched down at about 2.6 kilometres per second after which pyrotechnically fired blades to sever it from the crane.

In the course of the touchdown, the spacecraft collected about 30 gigabytes of knowledge and greater than 23,000 pictures, stated Perseverance group member Dave Gruel at JPL through the press convention. NASA has begun to release these images to the general public. The group has additionally launched the primary audio ever recorded on Mars. Whereas the microphone didn’t work through the touchdown, it did report the Martian breeze blowing over the rover as soon as it was on the floor.

You possibly can hear within the clip under the high-pitched sound of the rover with a decrease rumble of slight wind:


The primary few checks on the spacecraft’s standing have gone properly, so the group is now shifting on to carry out additional checks and calibrations. “The wheels, if you happen to observed within the picture now, are off to the facet. We will probably be performing a wiggle, we’ll straighten these up, we’ll do a brief drive and…deploy the robotic arm after which proceed with additional in-depth checkouts,” stated mission group member Jessica Samuels at JPL within the press convention.

After these checks, Perseverance will begin roving the Crimson Planet, taking samples that will probably be returned to Earth by a deliberate future mission and searching for indicators that Mars could have as soon as hosted life. Researchers have already begun analysing the photographs from close to the place the rover landed to find out what varieties of rocks are there and the way they had been fashioned.
