NASA’s Perseverance Rover Reaches the Top Rim of the Jezero Crater

In 2018, NASA mission planners selected the Jezero Crater as the future landing site of the Perseverance rover. This crater was a natural choice, as it was once an ancient lake bed, as evidenced by the delta fan at its western edge. On Earth, these features form in the presence of flowing water that gradually deposits sediment over time. Combined with the fact that the Jezero Crater’s delta feature is rich in clays, this makes the region a prime target to search for biosignatures – evidence of past (and maybe present) life on Mars!

In recent news, NASA announced that the Perseverance rover had reached the top of Jezero Crater’s rim at a location the science team calls “Lookout Hill.” The rover spent the previous three and a half months climbing the rim, covering a distance of 500 vertical meters (1,640 vertical feet) and making science observations along the way. Now that it has crested the rim, Perseverance can begin what the mission team calls its “Northern Rim” campaign. Over the next year, the rover is expected to drive 6.4 km (4 mi) and visit up to four sites of interest where it will obtain geological samples.

The hits just keep on coming from the Mars Perseverance rover. It’s exploring Jezero Crater on the Red Planet, looking for evidence of microbial life in the planet’s ancient (or even recent) past. Recently it spotted a very strange-looking rock with black and white stripes. Its appearance and location sparked a lot of questions. Perseverance team members have named it “Freya Castle.”

Ancient Rocks in Mars’ Jezero Crater Confirm Habitability

According to NASA’s Perseverance rover, ancient rocks in Jezero Crater formed in the presence of water. These sedimentary rocks are more than 3.5 billion years old and may predate the appearance of life on Earth. When and if these samples are returned to Earth, scientists hope to determine if they hold evidence of ancient Martian life.

Perseverance Found Some Strange Rocks. What Will They Tell Us?

This image shows a jumbled field of light toned rocks with unusual ‘popcorn’-like textures and abundant mineral veins. NASA's Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. This image was acquired on June 10, 2024 (Sol 1175) at the local mean solar time of 14:04:57.

NASA’s Perseverance Rover has left Mount Washburn behind and arrived at its next destination, Bright Angel. It found an unusual type of rock there that scientists are calling ‘popcorn rock.’ The odd rock is more evidence that water was once present in Jezero Crater.

NASA is Considering Other Ways of Getting its Mars Samples Home

In 2021, NASA’s Perseverance rover landed in the Jezero Crater on Mars. For the next three years, this astrobiology mission collected soil and rock samples from the crater floor for eventual return to Earth. The analysis of these samples is expected to reveal much about Mars’ past and how it transitioned from being a warmer, wetter place to the frigid and desiccated place we know today. Unfortunately, budget cuts have placed the future of the proposed NASA-ESA Mars Sample Return (MSR) mission in doubt.

As a result, NASA recently announced that it was seeking proposals for more cost-effective and rapid methods of bringing the samples home. This will consist of three studies by NASA and the Johns Hopkins University Applied Physics Laboratory (JHUAPL). In addition, NASA has selected seven commercial partners for firm-fixed-price contracts for up to $1.5 million to conduct their own 90-day studies. Once complete, NASA will consider which proposals to integrate into the MSR mission architecture.

Perseverance Wraps Up Over 1,000 Days on Mars. Still Going Strong

I can remember when Perseverance was launched, travelled out into the Solar System and landed on Mars in February 2021.  In all the time since it arrived, having clocked up 1000 days of exploration, it has collected 23 samples from different geological areas within the Jezero Crater. The area was once home to an ancient lake and if there is anywhere on Mars to find evidence of ancient (fossilised) life, it is here.

The Ingenuity Team Downloads the Final Data from the Mars Helicopter. The Mission is Over

Ingenuity Site

I really can’t believe that the Ingenuity helicopter on Mars took its maiden voyage in April 2021. On the 16th April 2024, engineers at NASA have received the final batch of data from the craft which marks the final task of the team. Ingenuity’s work is not over though as it will remain on the surface collecting data. For the engineers at NASA, they have their sights set on Dragonfly, a new helicopter destined for Titan.

Perseverance Finds its Dream Rock

This Martian rock, named Bunsen Peak, contains minerals that formed in the presence of water. On Earth, these water-deposited carbonate minerals are good at preserving ancient organic material. Image Credit: NASA/JPL-Caltech

If there’s a Holy Grail on Mars, it’s probably a specific type of rock: A rock so important that it holds convincing clues to Mars’ ancient habitability.

Perseverance might have just found it.

Grabbing Samples from the Surface of Mars

ESA's Sample Return Mission arm

As if the Mars Perseverance Rover and Ingenuity Drone were not exciting enough then the next step in this audacious mission takes it to a whole new level. Mars Sample Return Mission is to follow along, collect and return the samples collected by Perseverance back to Earth. However the status of Mars Sample Return is uncertain as engineers are still working on technology to retrieve the samples. The current challenge is the gripper arm that will collect the samples and stow them safely and securely before transportation without damaging them.

Ingenuity Won’t Fly Again Because It’s Missing a Rotor Blade

Ingenuity has been the first aerial vehicle on another world. NASA announced the end of the Martian helicopter’s life at the end of its 72nd flight. During the flight there had been a problem on landing and, following the incident a few photos revealed chips in one of the rotor blades but nothing too serious. New images have been revealed that show the craft is missing one of its rotor blades entirely!
