Humanity has by no means seen something like this earlier than.
The unprecedented footage takes viewers alongside for Perseverance’s harrowing experience, even exhibiting the second the rover, nonetheless hooked up through cables to its “sky crane” descent stage, hit the purple dust on Jezero’s flooring.
“For individuals who marvel the way you land on Mars, or why it’s so tough, or how cool it might be to take action — you want look no additional,” performing NASA Administrator Steve Jurczyk said in a statement today (Feb. 22), when the entry, descent and touchdown (EDL) footage was unveiled.
“Perseverance is simply getting began and already has offered a number of the most iconic visuals in space exploration history,” Jurczyk added. “It reinforces the outstanding stage of engineering and precision that’s required to construct and fly a automobile to the Crimson Planet.”
Perseverance’s EDL digicam system additionally incorporates a microphone, which the workforce had hoped would seize dashing Martian winds and different EDL sounds. That did not occur, however the mic did swap on after landing, recording the first-ever audio on the surface of another 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 identify.)
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 almost as sharp or full because the one NASA unveiled right this moment.
We bought to see Curiosity’s warmth protect 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 regarded up and one other that regarded down.
Collectively, these cameras captured greater than 23,000 photographs throughout Perseverance’s Thursday descent, workforce members mentioned. The workforce stitched lots of the pictures 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 desires,” Perseverance’s EDL lead Al Chen, of NASA’s Jet Propulsion Laboratory (JPL) in Southern California, mentioned throughout a information convention right this moment.
Chen mentioned he and his colleagues will pore over the footage for years to return, gleaning insights that can support future Mars touchdown efforts. And the video’s influence will prolong far past the engineering and space-science communities, serving to encourage common people all around the world, NASA officers mentioned.
“What we have seen right here right this moment is admittedly nothing in need of superb,” Thomas Zurbuchen, affiliate administrator for NASA’s Science Mission Directorate, mentioned throughout right this moment’s information convention. “That video, I consider, ought to turn into obligatory viewing for younger individuals who not solely wish to discover different worlds and construct spacecraft to take them there but additionally wish to be a part of various groups attaining all of the audacious targets 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 protect and the rover itself, in their various locations 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 historic 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 Area Company marketing campaign will haul to Earth as early as 2031.
Perseverance’s mission consists of a number of groundbreaking know-how demonstrations as nicely. 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, making an attempt to turn into the primary rotorcraft ever to fly on a world past Earth.
One other tech demo, known as MOXIE (quick for “Mars Oxygen In-Situ Useful resource Utilization Experiment”), is designed to generate oxygen from the skinny Martian atmosphere, which is 95% carbon dioxide by quantity. If MOXIE works as deliberate, its scaled-up descendants may 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 digicam. 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 may 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 business, 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 digicam lead Dave Gruel, additionally of JPL, mentioned throughout right this moment’s information convention, simply after enjoying a snippet of the historic Martian sound.
The workforce continues to be working to find out why the microphone did not work as deliberate throughout EDL, Gruel mentioned. However preliminary analyses recommend there might have been some form of communications concern involving the mic’s “digitizer puck,” which permits the instrument to hyperlink up with Perseverance’s onboard laptop.
“We’re not precisely certain why it occurred,” Gruel mentioned. “It may 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 might even have the ability to collect stereo sound in some unspecified time in the future, working the EDL and SuperCam mics in live performance, workforce members have mentioned.

Perseverance getting on top of things
Perseverance is just not but prepared to start out its science work in earnest; the Mars 2020 workforce continues to be within the technique of trying out the rover’s devices and subsystems. The information up to now is superb on this entrance.
“I’m completely satisfied to report that Perseverance is wholesome,” Perseverance floor mission supervisor Jessica Samuels, additionally of JPL, which manages the Mars 2020 mission, mentioned throughout right this moment’s information convention.
The workforce has already executed 5,000 rover instructions on the floor, Samuels added, and every little thing 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 photograph 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 workforce 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 workforce will proceed prepping for the primary huge mission milestone on the floor — getting Ingenuity into the skies.
These demonstration flights will doubtless occur this spring, permitting Perseverance to start out its science and sampling work in earnest this summer season, mission workforce members have mentioned.
There must be loads of time to get every little thing carried out. Mars 2020’s prime mission lasts for one Mars yr, or about 687 Earth days. And the rover might maintain driving far into the longer term; Curiosity, in spite of everything, continues to be going sturdy right this moment.
