Mars Guy notes that NASA’s Perseverance Mars rover has arrived among some truly enigmatic rocks – pockmarked with holes.
“In places they display little knobby protuberances while nearby they have circular holes. Maybe they’re unrelated to each other,” Mars Guy explains, “or maybe some holey rocks on Earth can help explain both.”
