Perseverance Rover Collects Rare Igneous Rock Sample on Mars

NASA’s Perseverance rover collected a rare crystalline igneous rock sample named Singita in the Lac de Charmes region of Mars, located outside the rim of Jezero crater, planetary.org reported. Stack Morgan explained that the rock was likely buried about 1 kilometer deep in the Martian crust before an asteroid or comet impact threw it to the surface.

Drilling the Hard Singita Rock Outside Jezero Crater

Perseverance extracted the Singita sample in the Lac de Charmes region, sitting outside the Jezero crater where the rover originally landed five years ago. Because Jezero formed from a giant impact roughly 3.9 billion years ago, scientists did not anticipate finding rocks older than that within the crater, and Singita marks the first crystalline igneous rock sample gathered by the rover outside the crater walls.

Stack Morgan noted that the rock’s age likely matches the Jezero impact event or could predate it by several hundred million years. The sample might even represent a ejected fragment from the formation of the Isidis Basin, one of the largest impact structures on Mars. However, confirming the exact age of the Singita sample remains impossible without returning it to Earth for laboratory analysis.

Overcoming Hardware Challenges During the Collection Attempt

Collecting the sample proved exceptionally difficult for the rover team. After going more than a year without capturing a new core, Perseverance nearly failed to drill the rock altogether, planetary.org reported. Stack Morgan stated that Singita was so unusually hard that the initial drilling attempt failed completely. The rover operations team had to switch to a different, less-frequently used drill bit before finally succeeding in extracting the core.

Building on this momentum, Stack Morgan announced that Perseverance will remain in the Lac de Charmes area to gather two additional samples. This upcoming campaign will specifically target another crystalline igneous rock that is younger than Singita, providing a broader geological comparison for the region.

Frequently Asked Questions About the Singita Mars Sample

Where exactly did Perseverance find the Singita rock?

Perseverance discovered and drilled the Singita rock in the Lac de Charmes region of Mars, which sits outside the rim of the Jezero crater where the rover originally landed five years ago.

Why was drilling the Singita rock so difficult for the rover?

Stack Morgan reported that the rock was exceptionally hard, causing the rover’s first drilling attempt to fail after more than a year of the vehicle not collecting any new samples. The mission team had to switch to a different, less-used drill bit to successfully extract the core.

Can scientists determine the exact age of the Singita sample on Mars?

No, there is currently no way to know the rock’s precise age without transporting the sample back to Earth for comprehensive laboratory testing.
