ALT A close-up shot of a calibration target the Perseverance rover uses for its SHERLOC instrument. The bottom row contains five samples of spacesuit material. The samples include a piece of polycarbonate helmet visor; Vectran, a cut-resistant material used for the palms of astronaut gloves; two kinds of Teflon, which has dust-repelling nonstick properties; and a commonly used spacesuit material called Ortho-Fabric. This last fabric features multiple layers, including Nomex, a flame-resistant material found in firefighter outfits; Gore-Tex, which is waterproof but breathable; and Kevlar, a strong material used in bulletproof vests that makes spacesuits more rip-resistant.

ALT A close-up view of a Martian rock sample captured inside a cylindrical sample tube by the Perseverance rover. The rock appears textured and irregularly shaped, with a light gray and brown coloration. The tube's interior is slightly blurred around the edges, focusing attention on the central rock.
