Perseverance photo shows the moment its spacecraft crash landed

NASA’s Perseverance rover landed safely on Mars last week, with dramatic video showing the final moments before touchdown. Mars landings are highly complex and full of risk, so much so that space engineers have dubbed the procedure the “seven minutes of terror.”

But even after Perseverance’s six wheels touched the martian surface and the landing was confirmed a success, there were still some very important maneuvers that had to take place in order to ensure the safety of the rover and the integrity of its intended research area.

They involved the rocket-powered descent stage that lowered Perseverance to the surface in those final crucial moments. First, the descent stage had to move well away from Perseverance, and second, it had to locate a safe spot for an intended crash landing.

Both of these maneuvers were executed successfully, and Perseverance on Wednesday tweeted a photo of the moment the descent stage came down on the martian surface a short distance away.

“A moment of respect for the descent stage,” Perseverance tweeted. “Within two minutes of safely delivering me to the surface of Mars, I caught the smoke plume on one of my Hazcams from its intentional surface impact — an act that protected me and the scientific integrity of my landing site.”

Perseverance has a total of six Hazcams among its collection of 23 image-gathering devices — the most on any NASA Mars rover to date.  With four on the front and two on the back, the Hazcams’ primary function is to detect hazards in the rover’s pathway, which could include everything from large rocks and boulders to trenches and sand dunes.

Engineers will also use the front Hazcams to help it move Perseverance’s robotic arm when taking measurements and photos, and for collecting rock and soil samples.

But the Hazcams don’t offer the best-quality imagery. Far more detailed photos will be captured by Perseverance’s more powerful Navcams (navigation cameras) — the rover recently sent back its first color panorama showing off its new home.

NASA has wonderful news for its plucky Mars helicopter
NASA's Ingenuity helicopter.

NASA’s Ingenuity Mars helicopter made history in April 2021 when it became the first aircraft to achieve powered, controlled flight on another planet.

With Mars’ atmosphere much thinner than Earth’s, engineers at NASA’s Jet Propulsion Laboratory (JPL) weren’t certain if they could build a machine capable of obtaining lift on the red planet, let alone creating one able to fly reliably. But with its long, fast-spinning blades, Ingenuity has exceeded expectations, flying over long distances during multiple flights.

Mars rover Perseverance is heading for the Jezero delta
NASA’s Perseverance Mars rover used its Left Navigation Camera (Navcam) to acquire an image on Feb 24, 2022 (sol 361) of target Sid, a higher standing boulder seen here just above the rover’s arm. Scientists plan to sample this rock before the rover heads to the delta for the mission’s next science campaign.

Having recently passed the one-year mark in exploring Mars's Jezero Crater, the Perseverance rover will soon be packing up and heading off to a new and exciting location: The Jezero delta. As the site of an ancient river delta, this area is one of the most promising locations to search for evidence of ancient life, as it was once an area of warm, shallow water that would be the ideal conditions for the emergence of life.

Until now, the Perseverance rover has been exploring the floor of the Jezero crater and collecting rock samples which will be brought back to Earth for analysis by future missions. Now, the rover will perform a week of analysis before grabbing a sample of a type of rock called Ch’ał which hasn't been sampled so far. With that sample collected, Perseverance will then be heading to the delta to learn more about the history of water in the region.

All the things the Perseverance rover has achieved in its first year on Mars
Perseverance snapped this view of a hill called “Santa Cruz” on April 29, 2021. About 20 inches (50 centimeters) across on average, the boulders in the foreground are among the type of rocks the rover team has named “Ch’ał” (the Navajo term for “frog” and pronounced “chesh”). Perseverance will return to the area next week or so.

It's been one year since NASA's Perseverance rover made its remarkable landing on Mars. Twelve months on, NASA has shared a roundup of all the achievements the rover has made in its quest to understand the Jezero crater, where it landed, and in its quest to search for evidence of ancient life.

One of the rover's major achievements was collecting samples of Mars rock, which proved tricky at first due to the rock being more crumbly than expected. However, despite the challenges the rover has managed to collect six samples so far which are sealed up in tubes and will be left on the planet's surface for a future mission to collect and eventually bring back to Earth for study.
