After an extended weekend with none updates or imagery from the, NASA launched a spectacular bounty of video Monday, together with never-before-seen footage capturing the to the floor of the crimson planet.
While earlier landers captured nonetheless pictures throughout descent that later had been stitched collectively to kind a type of stop-action film, Perseverance was outfitted with “ruggedized” off-the-shelf video cameras to shoot high-resolution imagery of the rover’s plunge to touchdown on the ground of.
Over the weekend, engineers on the Jet Propulsion Laboratory in Pasadena, California, the place Perseverance was constructed, downlinked 30 gigabytes of information from the rover, together with 23,000 pictures and video frames. That allowed them to present the general public a fowl’s eye view of a touchdown on Mars.
“This is the first time we’ve been able to actually capture an event like the landing of a spacecraft on Mars,” stated JPL Director Michael Watkins. “We will learn something by looking at the performance of the vehicle in these videos. But a lot of it is also to bring you along on our journey, our touchdown to Mars, and of course, our surface mission as well. These are really amazing videos.”
One digital camera mounted on the again of Perseverance’s flying saucer-like aeroshell captured crystal-clear views of the spacecraft’s 70.5-foot-wide parachute unfurling within the supersonic slipstream, inflating in a half second to behave as a 60,000-pound brake, slowing the craft from just below 1,000 mph to a extra sedate 200 mph.
Equally spectacular views wanting down confirmed the approaching floor under because the 1-ton rover swayed gently underneath the parachute. The rover then fell free and its rocket powered backpack fired up, guiding the craft to a hazard-free touchdown web site it chosen earlier.
As the backpack lowered Perseverance to the floor, exhaust plumes from the descent automobile’s eight engines kicked up swirling clouds of mud that briefly obscured the lander. Then, with its wheels on the bottom, the assist cables had been reduce and a digital camera on Perseverance confirmed the backpack lifting away and flying out of sight.
Along with the unprecedented video, NASA additionally launched extra pictures from the floor displaying the rover’s touchdown web site in Jezero Crater, which as soon as held a 28-mile-wide lake fed by a river that deposited sediments in a broad delta. Cliffs marking the sting of that delta some 1.2 miles away to the northwest might be clearly seen by Perseverance’s cameras.
Deputy undertaking supervisor Matt Wallace stated the thought to place video cameras on board to doc the rover’s entry, descent and touchdown got here after he purchased his daughter a small sports activities digital camera that she wore in a harness whereas working towards gymnastics.
“She did a back flip, and I don’t know about you, but I cannot do a back flip,” he stated. “But when she showed me the video … I had a glimpse into what it would be like if I could do a back flip. And that was the moment that inspired a phone call to my friend (Perseverance camera engineer) Dave Grohl, and that’s what led to this system.”
Along with 25 cameras, the rover additionally carries two microphones. One did not work throughout descent, however the different captured the sounds of the Martian wind blowing previous. NASA launched a snippet of audio picked up by the rover’s microphone — the primary sound ever recorded on one other planet.
Launched final July, Perseverance reached Mars on Thursday, February 18, plunging into the ambiance for a seven-minute descent.
The river and the lake it fed some 3.5 billion years in the past are lengthy gone, however scientists say remnants of previous microbial life, if such life existed, might preserved in lakebed deposits. Perseverance is the primary lander despatched to Mars particularly to search for such “biosignatures” and to cache soil and rock samples for eventual return to Earth.
Perseverance’s descent, like that of the Curiosity rover earlier than it, is called “seven minutes of terror” due to the acute entry surroundings and the myriad occasions that should occur on time and with out intervention from Earth to finish a profitable touchdown.
Despite guarantees earlier than touchdown that “raw” pictures from the rover’s hazard avoidance cameras and others could be posted as they got here in, lower than half a dozen had been launched by Friday night and none confirmed up over the weekend.
That touched off concern amongst house fanatics, however Thomas Zurbuchen, NASA’s science director, tweeted Sunday the main focus was on downloading on-board video and information in regards to the well being of the rover’s methods.
“Since the @NASAPersevere landing, we’ve been prioritizing two types of data: first-of-its-kind footage from the rover’s entry, descent & landing. And, health & safety data for the rover & its subsystems,” he tweeted.
He later added: “I am so proud of this @NASAPersevere team for working so hard and diligently and for being able to deliver things to us ahead of schedule because they know the intense public interest.”
