Incredible Perseverance Rover Mars Landing

• On Thursday February 18th, NASA’s Perseverance rover reached Mars’ thin atmosphere. The rover’s ‘jetpack’ lowered the rover on tethers near to the planet’s surface where the rover disengaged from the jetpack and descended by parachute to the ground. Meanwhile, the Mars Reconnaissance Orbiter (which has been orbiting Mars since 2006) flew overhead taking pictures of the descent and landing. The orbiter will relay data from the rover on the ground to the science team back on Earth. The rover and its jetpack were also snapping images along the way.
• While the first images taken by the Mars Reconnaissance Orbiter’s HiRISE camera on Thursday evening were black and white glimpses showing the rover safely landing on Mars, by Friday color images of the ‘Red Planet’ were being transmitted from the rover itself.
• Perseverance landed about 1.2 miles away from the Jezero Crater river delta, which hosted a lake 3.9 billion years ago. The rover switched over to the software it will use while driving on the Martian surface where it will spend the next two years investigating the crater and delta in search for evidence of ancient life that may have existed when Mars was a more habitable place.
• These first images shared during a NASA press conference were “exhilarating” for the team. A camera on the descent stage of the rover spacecraft captured a unique perspective. “This shot from a camera on my jetpack captures me in midair, just before my wheels touched down,” related the Perseverance rover on its Perseverance Twitter account. “The moment that my team dreamed of for years, now a reality.” “An open horizon, with so much to explore. Can’t wait to get going,” the Perseverance account tweeted. ”Dare mighty things.”
• “The team is overwhelmed with excitement and joy to have successfully landed another rover on the surface of Mars,” said Adam Steltzner, the Perseverance rover’s chief engineer. “When we do such investments, we do them for humanity, and we do them as a gesture of our humanity.” “We can only hope, in our efforts to engineer spacecraft and explore our solar system, that we might be able contribute yet another iconic image to this collection, and I’m happy to say that I’m hopeful that today we can with this.”
• Aaron Stehura, deputy phase lead for entry, descent and landing also reflected on the moment the science team saw the image of the rover from the perspective of the ‘jetpack’ descent stage. “This is something that we’ve never seen before. It was stunning and the team was awestruck. And, you know, there’s just a feeling of victory that we’re able to capture these and share them with the world.” After the successful landing, members of the team celebrated with virtual parties, ice cream and the best night’s sleep they’ve have in a long time.
• “The rover is doing great and is healthy on the surface of Mars and continues to be highly functional and awesome,” said Pauline Hwang, strategic mission manager for the rover. This weekend, the rover will go through some hardware checkouts to make sure everything is working properly, Hwang said. The head, or mast, will unfold and cameras on the mast will capture more images of the rover’s surroundings to provide a panorama, as well as a “selfie” panorama of the rover.
• ‘Ingenuity’, the little helicopter tucked up under the rover, will also go through a checkup before embarking upon a series of test flights over a 30-day period, said Hwang. The Perseverance rover will drive to a predetermined helipad location, lower the helicopter to the ground, roll back away from the helicopter. and record images and video of these historic flights. Ingenuity also carries two cameras and will be able to share its aerial views.
• Katie Stack Morgan, deputy project scientist for the rover has been helping to lead a team of 450 scientists around the world as they prepare to explore the Jezero Crater. Now, they’re ready to study these images and plot out a path for the rover to use as it navigates the intriguing features of the crater. The rover will explore nearby rocks on the crater floor to determine if they are volcanic basalt or sedimentary rocks and investigate the presence of a mineral called olivine that could be an explosive ash deposit, Morgan said.
• Holes present in some the rocks visible in images taken by the rover could suggest either gas that escaped the rocks if they were formed from lava, or fluids that dissolved part of the rock if they’re sedimentary. “Between us and the delta, we have a lot of interesting science to do,” said Morgan. “As soon as we got that color image from the surface of Mars, our chats lit up with the science team saying ‘look over here’ and’ look over here.’ And that’s exactly what we were hoping for… [W]e can’t believe that we’re really doing science now on the surface of Mars.”
After safely landing on the surface of Mars Thursday, NASA’s Perseverance rover has sent back a never-before-seen view: what it
looks like to land on Mars.
The rover also returned some beautiful postcards of its landing site.
The first image shared during a NASA press conference Friday was “exhilarating” for the team when they received it. It shows the rover nearing the Martian surface during entry, descent and landing. A camera on the descent stage of the spacecraft captured the perspective, something that wasn’t possible on previous missions.
“This shot from a camera on my ‘jetpack’ captures me in midair, just before my wheels touched down,” according to a tweet from the Perseverance Twitter account. “The moment that my team dreamed of for years, now a reality. Dare mighty things.”
Little dust plumes can be seen kicking up from the Martian surface, stirred by the engines landing the rover when it was just 6.5 feet above the surface.
“The team is overwhelmed with excitement and joy to have successfully landed another rover on the surface of Mars,” said Adam Steltzner, the rover’s chief engineer. “When we do such investments, we do them for humanity, and we do them as a gesture of our humanity.”
Steltzner cited iconic space images from the Apollo mission, like Buzz Aldrin on the surface of the moon, Voyager’s first image of Saturn and the Hubble Space Telescope’s awe-inspiring “Pillars of Creation” photo.
“We can only hope, in our efforts to engineer spacecraft and explore our solar system, that we might be able contribute yet another iconic image to this collection, and I’m happy to say that I’m hopeful that today we can with this.”
While the first images returned by the rover Thursday evening were black and white glimpses showing it safely landed on Mars, color images made available Friday show the characteristic red color of the Martian surface.
“An open horizon, with so much to explore. Can’t wait to get going,” the Perseverance account tweeted.
Rocks are also seen scattered across the flat surface of the landing site in Jezero Crater, but they’re small when compared to the large rover wheels.
Rocks spotted by the rover have holes in them — which has the scientists curious to see what would cause them.
Another tweet with the image read, “I love rocks. Look at these right next to my wheel. Are they volcanic or sedimentary? What story do they tell? Can’t wait to find out.”
The Mars Reconnaissance Orbiter’s HiRISE camera, which flew over the landing site as Perseverance was coming in for a landing, captured an incredible view as the spacecraft’s parachutes opened.
“The Beauty of Flight! HiRISE captured this image of @NASAPersevere on its way to the landing site from over 700 km (435 mi) away!” the HiRISE account tweeted.
