NASA’s latest rover captured first-of-its-kind footage of its February 18 landing and has recorded audio of Martian wind.
New video from NASA’s Mars 2020 Perseverance rover chronicles main milestones through the ultimate minutes of its entry, descent, and touchdown (EDL) on the Purple Planet on February 18 because the spacecraft plummeted, parachuted, and rocketed towards the floor of Mars. A microphone on the rover additionally has supplied the primary audio recording of sounds from Mars.
From the second of parachute inflation, the digital camera system covers everything of the descent course of, displaying a number of the rover’s intense trip to Mars’ Jezero Crater. The footage from high-definition cameras aboard the spacecraft begins 7 miles (11 kilometers) above the floor, displaying the supersonic deployment of essentially the most huge parachute ever despatched to a different world, and ends with the rover’s landing within the crater.

A microphone connected to the rover didn’t gather usable information through the descent, however the industrial off-the-shelf gadget survived the extremely dynamic descent to the floor and obtained sounds from Jezero Crater on February 20. About 10 seconds into the 60-second recording, a Martian breeze is audible for a couple of seconds, as are mechanical sounds of the rover working on the floor.
“For many who surprise the way you land on Mars – or why it’s so tough – or how cool it could be to take action – you want look no additional,” mentioned appearing NASA Administrator Steve Jurczyk. “Perseverance is simply getting began, and already has supplied a number of the most iconic visuals in area exploration historical past. It reinforces the exceptional stage of engineering and precision that’s required to construct and fly a automobile to the Purple Planet.”
Additionally launched Monday was the mission’s first panorama of the rover’s touchdown location, taken by the 2 Navigation Cameras positioned on its mast. The six-wheeled robotic astrobiologist, the fifth rover the company has landed on Mars, at present is present process an in depth checkout of all its methods and devices.
“This video of Perseverance’s descent is the closest you may get to touchdown on Mars with out placing on a strain go well with,” mentioned Thomas Zurbuchen, NASA affiliate administrator for science. “It ought to change into necessary viewing for younger ladies and men who not solely need to discover different worlds and construct the spacecraft that can take them there, but additionally need to be a part of the various groups attaining all of the audacious targets in our future.”
The world’s most intimate view of a Mars touchdown begins about 230 seconds after the spacecraft entered the Purple Planet’s higher ambiance at 12,500 mph (20,100 kph). The video opens in black, with the digital camera lens nonetheless coated throughout the parachute compartment. Inside lower than a second, the spacecraft’s parachute deploys and transforms from a compressed 18-by-26 inch (46-by-66 centimeter) cylinder of nylon, Technora, and Kevlar into a completely inflated 70.5-foot-wide (21.5-meter-wide) cover – the most important ever despatched to Mars. The tens of 1000’s of kilos of drive that the parachute generates in such a brief interval stresses each the parachute and the automobile.
“Now we lastly have a front-row view to what we name ‘the seven minutes of terror’ whereas touchdown on Mars,” mentioned Michael Watkins, director of NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission for the company. “From the explosive opening of the parachute to the touchdown rockets’ plume sending mud and particles flying at landing, it’s completely awe-inspiring.”
The video additionally captures the warmth protect dropping away after defending Perseverance from scorching temperatures throughout its entry into the Martian ambiance. The downward view from the rover sways gently like a pendulum because the descent stage, with Perseverance connected, hangs from the again shell and parachute. The Martian panorama shortly pitches because the descent stage – the rover’s free-flying “jetpack,” which decelerates utilizing rocket engines after which lowers the rover on cables to the floor – breaks free, its eight thrusters partaking to place distance between it and the now-discarded again shell and the parachute.
Then, 80 seconds and seven,000 ft (2,130 meters) later, the cameras seize the descent stage performing the sky crane maneuver over the touchdown website – the plume of its rocket engines kicking up mud and small rocks which have doubtless been in place for billions of years.
“We put the EDL digital camera system onto the spacecraft not just for the chance to realize a greater understanding of our spacecraft’s efficiency throughout entry, descent, and touchdown, but additionally as a result of we needed to take the general public alongside for the trip of a lifetime – touchdown on the floor of Mars,” mentioned Dave Gruel, lead engineer for Mars 2020 Perseverance’s EDL digital camera and microphone subsystem at JPL. “We all know the general public is fascinated with Mars exploration, so we added the EDL Cam microphone to the automobile as a result of we hoped it may improve the expertise, particularly for visually-impaired area followers, and have interaction and encourage folks all over the world.”
The footage ends with Perseverance’s aluminum wheels making contact with the floor at 1.61 mph (2.6 kilometers per hour), after which pyrotechnically fired blades sever the cables connecting it to the still-hovering descent stage. The descent stage then climbs and accelerates away within the preplanned flyaway maneuver.
“If this had been an previous Western film, I’d say the descent stage was our hero using slowly into the setting Solar, however the heroes are literally again right here on Earth,” mentioned Matt Wallace, Mars 2020 Perseverance deputy undertaking supervisor at JPL. “I’ve been ready 25 years for the chance to see a spacecraft land on Mars. It was definitely worth the wait. Having the ability to share this with the world is a superb second for our staff.”
5 industrial off-the-shelf cameras positioned on three totally different spacecraft elements collected the imagery. Two cameras on the again shell, which encapsulated the rover on its journey, took footage of the parachute inflating. A digital camera on the descent stage supplied a downward view – together with the highest of the rover – whereas two on the rover chassis provided each upward and downward views.
The rover staff continues its preliminary inspection of Perseverance’s methods and its instant environment. Monday, the staff will take a look at 5 of the rover’s seven devices and take the primary climate observations with the Mars Environmental Dynamics Analyzer instrument. Within the coming days, a 360-degree panorama of Jezero by the Mastcam-Z needs to be transmitted down, offering the best decision have a look at the highway forward.
Extra Concerning the Mission
A key goal of Perseverance’s mission on Mars is astrobiology, together with the seek for indicators of historical microbial life. The rover will characterize the planet’s geology and previous local weather, pave the way in which for human exploration of the Purple Planet, and be the primary mission to gather and cache Martian rock and regolith.
Subsequent NASA missions, in cooperation with ESA (European House Company), would ship spacecraft to Mars to gather these sealed samples from the floor and return them to Earth for in-depth evaluation.
The Mars 2020 Perseverance mission is a part of NASA’s Moon to Mars exploration method, which incorporates Artemis missions to the Moon that can assist put together for human exploration of the Purple Planet.
JPL, which is managed for NASA by Caltech in Pasadena, California, constructed and manages operations of the Perseverance rover.
