Mars rover Perseverance is heading for the Jezero delta

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.

“Once we have our samples in stow, Perseverance will be kicking it into high gear around the northern tip of Séítah and west towards the delta,” Perseverance team member Brad Garczynski wrote in a blog post. “There we will have the opportunity to investigate sedimentary rock layers, clay minerals, and rounded boulders washed down from far beyond Jezero. These features are vestiges of Jezero’s watery past and clear indicators of an ancient habitable environment. If microbial life did exist here in the past, this is one of the best places to look for it as finely layered muds may have buried and preserved a record of that microbial activity.”

In addition to investigating these new features, researchers are preparing to plan Perseverance’s route using previously collected data from the rover’s Mastcam-Z and SuperCam instruments, as well as data collected by orbital explorers to look for the ideal exploration route. Plus, Perseverance will soon have the Ingenuity helicopter nearby to help plan out its route as well.

NASA’s Mars helicopter recently aced its 43rd flight, one that turned out to be its longest in almost a year.

During the February 11 flight, Ingenuity traveled 1,280 feet (390 meters) across the martian surface for 146 seconds, reaching a maximum altitude of 40 feet (12 meters) while reaching a top speed of 8.9 mph (4 meters per second). The flight was a repositioning mission in preparation for providing further assistance to NASA’s Perseverance rover as it continues to explore Jezero Crater.

NASA’s Perseverance Mars rover has been busy creating what the space agency recently said was “humanity’s first sample depot on another planet.”

The depot, which is essentially a flat patch of land, contains 10 titanium tubes holding samples of martian rock and dust collected by NASA’s rover in the two years since it landed on the red planet.

Mars Curiosity rover finds evidence of water where it was expected to be dry
Curiosity Rover

The key to understanding whether Mars was ever habitable is water. For life as we know it to thrive, liquid water needs to be present -- and we know that even though it is now dry, there was once liquid water on the surface of Mars. However, the history of water on Mars is complex, and scientists are still debating exactly how long water was present there and when the planet dried up.

And it's about to get more complex. Recently, the Curiosity rover has made an intriguing discovery suggesting that water was once present in an area that scientists had thought would be dry.
