Caption:

Planetary protection engineers at NASA's Jet Propulsion Laboratory in Southern California swab engineering models of the tubes that will store Martian rock and sediment samples as part of NASA s Mars 2020 Perseverance mission. Team members wanted to understand the transport of biological particles when the rover is taking rock cores. These measurements helped the rover team design hardware and sampling methods that meet stringent biological contamination control requirements.
