Mars exploration is ramping up to new heights, thanks to NASA's Perseverance rover. But what lies beneath can be just as tantalizing as the surface itself. Beyond simply collecting core samples, Perseverance is using cutting-edge technology to probe Martian rocks for hidden secrets that have been concealed under layers of dust.

Diving Deeper into Kenmore Rock

On June 3, Perseverance tackled a stubbornly intriguing rock dubbed "Kenmore." This rock isn’t just any ordinary specimen; it’s a bizarre puzzle that the rover aims to piece together. After grinding its surface to expose the underlying material, Perseverance initiated a detailed analysis of Kenmore’s geological makeup.

A Rock That Refused to Cooperate

According to Professor Ken Farley, a noble gas isotope geochemist at Caltech and the project’s deputy scientist, Kenmore was exceptionally challenging. Despite its outward appearance suggesting it was suitable for study, the rock’s unpredictable vibrations during the abrasion process posed difficulties. "It vibrated all over the place, and tiny fragments broke away," he explained. Luckily, they were able to delve deep enough to conduct a thorough examination.

Cutting-Edge Cleaning Techniques

Unlike previous missions that relied on mechanical brushes or wire bristles, Perseverance uses a sophisticated Dust Removal Tool (gDRT) that sprays nitrogen gas to clear away debris without touching the rock surface. This method minimizes the risk of Earthly contaminants, allowing for a pristine analysis of the Martian geology.

Advanced Tools and Techniques Uncover Secrets

Once the dust was blasted away, Perseverance employed its advanced sensors to gather detailed data. A camera known as WATSON captured close-up images, while the SuperCam shot thousands of laser pulses at the freshly abraded area. This combination of techniques revealed that Kenmore is rich in clay minerals containing water molecules bound to iron and magnesium—an essential clue pointing toward Mars’ wet past.

New Discoveries on the Red Planet

Not stopping at clay, further analysis with SHERLOC and PIXL instruments uncovered even more exciting findings. For the first time during the mission, a manganese hydroxide mineral was detected—a remarkable discovery poised to change our understanding of Martian geology. With Kenmore behind it, Perseverance is now set to explore other intriguing regions of Jezero Crater.

Pushing Boundaries and Breaking Records

On June 19, marking mission day 1,540, Perseverance made headlines again by achieving a record autonomous drive distance of 1,348 feet (411 meters)—210 feet further than its previous record from April 2023. This feat was made possible by the rover’s AutoNav system, allowing it to traverse the Martian landscape efficiently while the team guides its overall journey.

As Camden Miller, the rover's driver at JPL, put it: “Every day we operate on Mars, we learn how to maximize Perseverance’s capabilities, paving the way for future missions.”

The Future of Mars Exploration

With each rock, like Kenmore, peeling back layers of Mars' enigmatic history, the data gathered is invaluable. Insights gained today will help map out not only where future missions should venture but also which rocks can provide essential resources for future colonists.
