"These are amongst the oldest rocks in the Solar System," says Kenneth Farley, emphasizing the significance of exploring the Jezero Crater's rim, where Perseverance now operates.
Researchers hope that the rocks outside of Jezero Crater hold signs of whether Mars might have once sustained extraterrestrial life when it was warmer and wetter than today.
Perseverance has already placed 10 tubes on the crater floor in a 'sample depot' where a future mission could pick them up for potential biological analysis.
NASA is trying to figure out how to bring any of the samples back to Earth for analysis, as thorough study is essential for confirming signs of life.
