“So far, the only Martian rocks we’ve ever been able to study on Earth have been meteorites. Getting our hands on intact Mars rocks, carefully stored and protected from contamination, will be invaluable to planetary science,” said Joseph Razzell Hollis, a postdoctoral fellow at London’s Natural History Museum.

Hollis is also an author on a research paper recently published in the journal Nature titled “Diverse organic-mineral associations in Jezero crater, Mars.”

I’m confused: is this article just summarizing Hollis’s paper, or is this a new discovery and they asked Hollis to comment because he’d previously written a relevant paper?
