NASA simply launched superb, high-definition video that its car-sized Perseverance rover captured throughout its epic touchdown inside Mars’ Jezero Crater on Thursday (Feb. 18).
The unprecedented footage takes viewers alongside for Perseverance’s harrowing experience, even displaying the second the rover, nonetheless hooked up by way of cables to its “sky crane” descent stage, hit the purple dust on Jezero’s flooring.
“For individuals 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,” performing NASA Administrator Steve Jurczyk mentioned in a press release as we speak (Feb. 22), when the entry, descent and touchdown (EDL) footage was unveiled.
“Perseverance is simply getting began and already has supplied among the most iconic visuals in area exploration historical past,” Jurczyk added. “It reinforces the outstanding stage of engineering and precision that’s required to construct and fly a car to the Crimson Planet.”
Perseverance’s EDL digital camera system additionally incorporates a microphone, which the group had hoped would seize speeding Martian winds and different EDL sounds. That did not occur, however the mic did change on after landing, recording the first-ever audio on the floor of one other world.

Documenting the ‘seven minutes of terror’
Perseverance is not the primary robotic to doc its arrival on Mars. The six-wheeled robotic’s predecessor, NASA’s Curiosity rover, captured imagery of its personal “seven minutes of terror” landing in August 2012. (It takes NASA spacecraft about seven minutes to achieve the floor after hitting the highest of the Martian ambiance, and the journey down is hazardous in a number of methods, therefore the title.)
Curiosity employed the identical primary touchdown technique as Perseverance, counting on a supersonic parachute and a rocket-powered sky crane, amongst different tech, to get down safely. However the earlier rover’s EDL footage was not practically as sharp or full because the one NASA unveiled as we speak.
We bought to see Curiosity’s warmth defend fall away, for instance, however the imagery stopped lengthy earlier than the rover touched down. And we did not get the vary of viewpoints that the Perseverance video offers. The newer mission put a number of EDL cameras on the rover’s protecting backshell, one on the underside of the sky crane and two on Perseverance itself — one which appeared up and one other that appeared down.
Collectively, these cameras captured greater than 23,000 photographs throughout Perseverance’s Thursday descent, group members mentioned. The group stitched lots of the images collectively to supply the video, which begins about 230 seconds into the rover’s seven minutes of terror.
“These movies and these photographs are the stuff of our goals,” Perseverance’s EDL lead Al Chen, of NASA’s Jet Propulsion Laboratory (JPL) in Southern California, mentioned throughout a information convention as we speak.
Chen mentioned he and his colleagues will pore over the footage for years to return, gleaning insights that may support future Mars touchdown efforts. And the video’s affect will prolong far past the engineering and space-science communities, serving to encourage common of us all around the world, NASA officers mentioned.
“What we have seen right here as we speak is absolutely nothing wanting superb,” Thomas Zurbuchen, affiliate administrator for NASA’s Science Mission Directorate, mentioned throughout as we speak’s information convention. “That video, I imagine, ought to turn into necessary viewing for younger individuals who not solely need to discover different worlds and construct spacecraft to take them there but in addition need to be a part of numerous groups attaining all of the audacious objectives of our future.”
The excellent EDL imagery additionally helped scientists rapidly pinpoint the place Perseverance’s accent items touched down. On Friday (Feb. 19), NASA’s Mars Reconnaissance Orbiter, which has been circling the Crimson Planet since 2006, imaged the mission’s backshell and related parachute, its sky crane and warmth defend and the rover itself, of their numerous places inside Jezero.
A pioneering mission
Perseverance is the centerpiece of NASA’s $2.7 billion Mars 2020 mission, which is pushing the boundaries of exploration in a number of methods. The six-wheeled rover will hunt for indicators of historical organisms on the ground of Jezero, which harbored a lake and a river delta billions of years in the past. No robotic has searched for all times on the Martian floor since NASA’s twin Viking landers ceased operations within the early 1980s.
Mars 2020 additionally kicks off the first-ever Mars sample-return effort. Perseverance will acquire and cache dozens of samples with particularly excessive astrobiological potential, which a joint NASA-European House Company marketing campaign will haul to Earth as early as 2031.
Perseverance’s mission contains a number of groundbreaking expertise demonstrations as properly. For instance, a tiny helicopter named Ingenuity flew to Mars on the rover’s stomach. Within the coming weeks, the 4-lb. (1.eight kilograms) craft will deploy and take to the skies, trying to turn into the primary rotorcraft ever to fly on a world past Earth.
One other tech demo, referred to as MOXIE (quick for “Mars Oxygen In-Situ Useful resource Utilization Experiment”), is designed to generate oxygen from the skinny Martian ambiance, which is 95% carbon dioxide by quantity. If MOXIE works as deliberate, its scaled-up descendants might assist astronauts get a foothold on the Crimson Planet, NASA officers have mentioned.

Sights and sounds
Then there are the microphones. Perseverance totes two — the EDL mic and one other in its rock-zapping SuperCam instrument.
Taking microphones to Mars is not new; NASA’s Mars Polar Lander spacecraft sported a mic, and the company’s Phoenix lander had one constructed into its descent digital camera. However neither of these devices returned any Martian sounds. Mars Polar Lander crashed throughout its landing try in December 1999, and Phoenix’s mic was by no means turned on out of concern that its use might intervene with the spacecraft’s touchdown. (Phoenix touched down safely in Might 2008 and loved a profitable floor mission.)
However we now have our first-ever true Martian audio, courtesy of Perseverance’s EDL mic. The industrial, off-the-shelf microphone recorded about 60 seconds of sound on Saturday (Feb. 20), together with a refined Martian breeze and a few whirs coming from Perseverance, NASA officers mentioned.
“Actually neat — overwhelming, if you’ll,” Perseverance EDL digital camera lead Dave Gruel, additionally of JPL, mentioned throughout as we speak’s information convention, simply after taking part in a snippet of the historic Martian sound.
The group remains to be working to find out why the microphone did not work as deliberate throughout EDL, Gruel mentioned. However preliminary analyses counsel there could have been some kind of communications concern involving the mic’s “digitizer puck,” which permits the instrument to hyperlink up with Perseverance’s onboard pc.
“We’re not precisely positive why it occurred,” Gruel mentioned. “It might have been the truth that there was simply a lot knowledge streaming into the system.”
However the microphone is working now, and Gruel and his colleagues plan to maintain gathering audio for so long as it lasts on the cruel, frigid Martian floor. Perseverance could even be capable to collect stereo sound sooner or later, working the EDL and SuperCam mics in live performance, group members have mentioned.
Sounds of Mars: Perseverance will put ears on the Crimson Planet for 1st time
Perseverance getting up to the mark
Perseverance will not be but prepared to start out its science work in earnest; the Mars 2020 group remains to be within the technique of trying out the rover’s devices and subsystems. The information thus far is excellent on this entrance.
“I’m joyful to report that Perseverance is wholesome,” Perseverance floor mission supervisor Jessica Samuels, additionally of JPL, which manages the Mars 2020 mission, mentioned throughout as we speak’s information convention.
The group has already executed 5,000 rover instructions on the floor, Samuels added, and the whole lot has “come again precisely how we have been wanting it to with respect to our well being checkouts and our instrument checkouts.”
The nuclear-powered Perseverance has already deployed its headlike mast and captured its first picture with its high-powered MastCam-Z imaging system. The rover has additionally captured many different photographs of its environment with its hazard-avoidance and navigation cameras, mission group members mentioned.
Over the approaching days, Perseverance will straighten out its wheels, deploy its robotic arm and carry out its first drive, Samuels mentioned. And the group will proceed prepping for the primary large mission milestone on the floor — getting Ingenuity into the skies.
These demonstration flights will doubtless happen this spring, permitting Perseverance to start out its science and sampling work in earnest this summer season, mission group members have mentioned.
There ought to be loads of time to get the whole lot carried out. Mars 2020’s prime mission lasts for one Mars yr, or about 687 Earth days. And the rover could maintain driving far into the long run; Curiosity, in spite of everything, remains to be going robust as we speak.
