After spending a long weekend without updates or images from, NASA released a spectacular and rich video on Monday, including footage never seen before. On the surface of the red planet.
Earlier landers captured still images during the descent and later stitched them together to create a sort of stop-action movie, but Perseverance is for taking high-resolution images of the landing rover’s plunge. The floor was equipped with a “rugged” off-the-shelf video camera..
Over the weekend, engineers at the Jet Propulsion Laboratory in Pasadena, California, where Perseverance was built, downlinked 30 gigabytes of data from Rover, including 23,000 images and video frames. It allowed them to give the public a bird’s-eye view of their landing on Mars.
“This is the first time I’ve actually been able to capture an event like the landing of a spaceship on Mars,” said JPL Director Michael Watkins. “Learn something by watching the performance of the vehicle in these videos, but much of it takes you to our journeys, touchdowns to Mars, and of course, our ground missions. That’s it. These are really great videos. “
Mounted on the back of Perseverance’s flying saucer-like aeroshell, a single camera captures a clear view of a 70.5-foot-wide parachute of a spacecraft deploying in a supersonic slipstream, expanding in 0.5 seconds. It then acted as a 60,000 pound brake, slowing down the aircraft. From just under 1,000 mph to 200 mph.
A similarly spectacular view overlooking, while a ton of rover gently sways under the parachute, showed the approaching ground below. The rover was then freed and a rocket-propelled backpack was launched, guiding the aircraft to the previously selected non-hazardous landing site.
As the backpack lowered its patience to the surface, the exhaust plumes from the eight engines of the descent vehicle kicked up a swirling cloud of dust, temporarily obscuring the lander. Then, with the wheels on the ground, I cut the support cable and the Perseverance camera showed that the backpack was lifted and invisible.
In addition to the unprecedented video, NASA has released more photos from the surface showing the landing site of the Jezero Crater Rover. The Jezero Crater once held a 28-mile wide lake supplied by a river that deposited sediments in a wide delta. The cliffs that mark the edge of the delta, about 1.2 miles northwest, are clearly visible on Perseverance cameras.
Deputy project manager Matt Wallace said the idea of equipping a video camera to record Rover’s entry, descent, and landing bought her daughter a small sports camera that she wore in her harness while practicing gymnastics. He said he was born later.
“She did a backflip, and I don’t know you, but I can’t do a backflip,” he said. “But when she showed me a video … I got a glimpse of what would happen if I could roll back, and that called my friend (patience camera engineer) Dave Grohl. It was the moment I called. That led to this system. “
In addition to the 25 cameras, the Rover also has two microphones. One didn’t work during the descent, but the other caught the sound of the Martian wind blowing through. NASA has released a fragment of audio picked up by Rover’s microphone. This is the first sound recorded on another planet.
Launched last July, Perseverance reached Mars on Thursday, February 18, and plunged into the atmosphere for a seven-minute descent.
The river and the lake it supplied about 3.5 billion years ago are a long time ago, but scientists say that the presence of microbial life debris from the past may be preserved in lake bottom sediments. I will. Patience is the first lander sent to Mars to specifically look for such “biosignatures” and eventually cache soil and rock samples to return to Earth.
Prior to that, patience drops like the Curiosity Rover were due to the extreme invasion environment and the myriad of events that had to occur on time without Earth intervention for a successful landing. Known as “Fear of Minutes”.
Less than half a dozen were released by Friday night, over the weekend, despite promises to be posted when “raw” images from Rover’s danger avoidance cameras etc. came in before landing. Did not see anything.
It touched on concerns among space enthusiasts, but NASA’s science director Thomas Zurbuchen tweeted on Sunday that he focused on downloading onboard videos and data on the health of Rover’s system.
“Since the landing of @NASAPersevere, we have prioritized two types of data: the first footage from the rover’s approach, descent and landing, and data on the health and safety of the rover and its subsystems. “He tweeted. ..
He later added, “This @NASAPersevere team is very proud to be able to deliver things earlier than planned because they work very hard and know the strong public interest.” I did.
