Watch the Perseverance rover land on Mars on this epic first-of-its-kind video
NASA simply launched wonderful, high-definition video that its car-sized Perseverance rover captured throughout its epic touchdown inside Mars’ Jezero Crater on Thursday (Feb. 18).Â
The unprecedented footage takes viewers alongside for Perseverance’s harrowing experience, even displaying the second the rover, nonetheless connected through cables to its “sky crane” descent stage, hit the crimson filth on Jezero’s flooring.âFor many who marvel the way you land on Mars, or why it’s so tough, or how cool it will be to take action â you want look no additional,” performing NASA Administrator Steve Jurczyk stated in a press release in the present day (Feb. 22), when the entry, descent and touchdown (EDL) footage was unveiled.Â
“Perseverance is simply getting began and already has supplied a few of 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 automobile to the Pink Planet.”
Perseverance’s EDL digital camera system additionally encompasses a microphone, which the staff 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 floor of one other world.Â

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 succeed in 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 fundamental 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 in the present day.Â
We obtained 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 â one which seemed up and one other that seemed down.
These movies and these photos are the stuff of our goals.
Al Chen, EDL lead at JPL
Collectively, these cameras captured greater than 23,000 photos throughout Perseverance’s Thursday descent, staff members stated. The staff stitched most of the images collectively to provide the video, which begins about 230 seconds into the rover’s seven minutes of terror.
“These movies and these photos are the stuff of our goals,” Perseverance’s EDL lead Al Chen, of NASA’s Jet Propulsion Laboratory (JPL) in Southern California, stated throughout a information convention in the present day.
Chen stated he and his colleagues will pore over the footage for years to return, gleaning insights that can help 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 stated.
“What we have seen right here in the present day is basically nothing wanting wonderful,” Thomas Zurbuchen, affiliate administrator for NASA’s Science Mission Directorate, stated throughout in the present day’s information convention. “That video, I consider, ought to develop 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 reaching 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 Pink Planet since 2006, imaged the mission’s backshell and linked parachute, its sky crane and warmth protect and the rover itself, of their varied areas 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 Nineteen Eighties.
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.Â
Perseverance’s mission consists of a number of groundbreaking expertise demonstrations as effectively. For instance, a tiny helicopter named Ingenuity flew to Mars on the rover’s stomach. Within the coming weeks, the 4-lb. (1.8 kilograms) craft will deploy and take to the skies, making an attempt to develop 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 Pink Planet, NASA officers have stated.

Sights and sounds
Then there are the microphones. Perseverance totes two â the EDL mic and one other in its rock-zapping SuperCam instrument.Â
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 Could 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 stated.
“Actually neat â overwhelming, if you’ll,” Perseverance EDL digital camera lead Dave Gruel, additionally of JPL, stated throughout in the present day’s information convention, simply after taking part in a snippet of the historic Martian sound.
The staff remains to be working to find out why the microphone did not work as deliberate throughout EDL, Gruel stated. However preliminary analyses counsel there might have been some type 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 stated. “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 tough, frigid Martian floor. Perseverance might even be capable to collect stereo sound in some unspecified time in the future, working the EDL and SuperCam mics in live performance, staff members have stated.

Perseverance getting in control
Perseverance is just not but prepared to start out its science work in earnest; the Mars 2020 staff remains to be within the strategy of trying out the rover’s devices and subsystems. The information up to now is superb on this entrance.
“I’m comfortable to report that Perseverance is wholesome,” Perseverance floor mission supervisor Jessica Samuels, additionally of JPL, which manages the Mars 2020 mission, stated throughout in the present day’s information convention.
The staff has already executed 5,000 rover instructions on the floor, Samuels added, and every 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 photos of its environment with its hazard-avoidance and navigation cameras, mission staff members stated.
Over the approaching days, Perseverance will straighten out its wheels, deploy its robotic arm and carry out its first drive, Samuels stated. And the staff will proceed prepping for the primary massive mission milestone on the floor â getting Ingenuity into the skies.
These demonstration flights will seemingly happen this spring, permitting Perseverance to start out its science and sampling work in earnest this summer time, mission staff members have stated.Â
There must be loads of time to get every thing executed. Mars 2020’s prime mission lasts for one Mars yr, or about 687 Earth days. And the rover might preserve driving far into the long run; Curiosity, in any case, remains to be going sturdy in the present day.
