New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds from Mars.
From the moment of parachute inflation, the camera system covers the entirety of the descent process, showing some of the rover’s intense ride to Mars’ Jezero Crater. The footage from high-definition cameras aboard the spacecraft starts 7 miles (11 kilometers) above the surface, showing the supersonic deployment of the most massive parachute ever sent to another world, and ends with the rover’s touchdown in the crater.
A microphone attached to the rover did not collect usable data during the descent, but the commercial off-the-shelf device survived the highly dynamic descent to the surface and obtained sounds from Jezero Crater on Feb. 20. About 10 seconds into the 60-second recording, a Martian breeze is audible for a few seconds, as are mechanical sounds of the rover operating on the surface.
“For those who wonder how you land on Mars – or why it is so difficult – or how cool it would be to do so – you need look no further,” said acting NASA Administrator Steve Jurczyk. “Perseverance is just getting started, and already has provided some of the most iconic visuals in space exploration history. It reinforces the remarkable level of engineering and precision that is required to build and fly a vehicle to the Red Planet.”
Also released Monday was the mission’s first panorama of the rover’s landing location, taken by the two Navigation Cameras located on its mast. The six-wheeled robotic astrobiologist, the fifth rover the agency has landed on Mars, currently is undergoing an extensive checkout of all its systems and instruments.
“This video of Perseverance’s descent is the closest you can get to landing on Mars without putting on a pressure suit,” said Thomas Zurbuchen, NASA associate administrator for science. “It should become mandatory viewing for young women and men who not only want to explore other worlds and build the spacecraft that will take them there, but also want to be part of the diverse teams achieving all the audacious goals in our future.”
The world’s most intimate view of a Mars landing begins about 230 seconds after the spacecraft entered the Red Planet’s upper atmosphere at 12,500 mph (20,100 kph). The video opens in black, with the camera lens still covered within the parachute compartment. Within less 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 fully inflated 70.5-foot-wide (21.5-meter-wide) canopy – the largest ever sent to Mars. The tens of thousands of pounds of force that the parachute generates in such a short period stresses both the parachute and the vehicle.
“Now we finally have a front-row view to what we call ‘the seven minutes of terror’ while landing on Mars,” said Michael Watkins, director of NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission for the agency. “From the explosive opening of the parachute to the landing rockets’ plume sending dust and debris flying at touchdown, it’s absolutely awe-inspiring.”
The video also captures the heat shield dropping away after protecting Perseverance from scorching temperatures during its entry into the Martian atmosphere. The downward view from the rover sways gently like a pendulum as the descent stage, with Perseverance attached, hangs from the back shell and parachute. The Martian landscape quickly pitches as the descent stage – the rover’s free-flying “jetpack,” which decelerates using rocket engines and then lowers the rover on cables to the surface – breaks free, its eight thrusters engaging to put distance between it and the now-discarded back shell and the parachute.
Then, 80 seconds and 7,000 feet (2,130 meters) later, the cameras capture the descent stage performing the sky crane maneuver over the landing site – the plume of its rocket engines kicking up dust and small rocks that have likely been in place for billions of years.
“We put the EDL camera system onto the spacecraft not only for the opportunity to gain a better understanding of our spacecraft’s performance during entry, descent, and landing, but also because we wanted to take the public along for the ride of a lifetime – landing on the surface of Mars,” said Dave Gruel, lead engineer for Mars 2020 Perseverance’s EDL camera and microphone subsystem at JPL. “We know the public is fascinated with Mars exploration, so we added the EDL Cam microphone to the vehicle because we hoped it could enhance the experience, especially for visually-impaired space fans, and engage and inspire people around the world.”
The footage ends with Perseverance’s aluminum wheels making contact with the surface at 1.61 mph (2.6 kph), and then pyrotechnically fired blades sever the cables connecting it to the still-hovering descent stage. The descent stage then climbs and accelerates away in the preplanned flyaway maneuver.
“If this were an old Western movie, I’d say the descent stage was our hero riding slowly into the setting Sun, but the heroes are actually back here on Earth,” said Matt Wallace, Mars 2020 Perseverance deputy project manager at JPL. “I’ve been waiting 25 years for the opportunity to see a spacecraft land on Mars. It was worth the wait. Being able to share this with the world is a great moment for our team.”
Five commercial off-the-shelf cameras located on three different spacecraft components collected the imagery. Two cameras on the back shell, which encapsulated the rover on its journey, took pictures of the parachute inflating. A camera on the descent stage provided a downward view – including the top of the rover – while two on the rover chassis offered both upward and downward perspectives.
The rover team continues its initial inspection of Perseverance’s systems and its immediate surroundings. Monday, the team will check out five of the rover’s seven instruments and take the first weather observations with the Mars Environmental Dynamics Analyzer instrument. In the coming days, a 360-degree panorama of Jezero by the Mastcam-Z should be transmitted down, providing the highest resolution look at the road ahead.
More About the Mission
A key objective of Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.
Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

This first image of NASA’s Perseverance Rover on the surface of Mars from the High Resolution Imaging Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) shows the many parts of the Mars 2020 mission landing system that got the rover safely on the ground. The image was taken on Feb. 19, 2021.
This annotated version of the image points out the locations of the parachute and back shell, the descent stage, the Perseverance rover, and the heat shield. Each inset shows an area about 650 feet (200 meters) across.
The rover itself sits at the center of a blast pattern created by the hovering descent stage that lowered it there using the sky crane maneuver. The descent stage flew off to crash at a safe distance, creating a V-shaped debris pattern that points back toward the rover. Earlier in the landing sequence, Perseverance jettisoned its heat shield and parachute, which can be seen on the surface in the separate locations illustrated.
These objects are highly visible on the surface of Mars now but will become dustier with time and slowly fade into the background over years. HiRISE will continue to image the Perseverance landing site to track the progress of the rover and changes with the other pieces of hardware that accompanied it.
MRO’s mission is managed by NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, for NASA’s Science Mission Directorate. Lockheed Martin Space in Denver, built the spacecraft. The University of Arizona provided and operates HiRISE.
