NASA awards $2M to team making 3D-printed sensors for rovers

A Goddard Space Flight Center team has won a $2-million NASA award to develop 3D printed sensors that could be deployed on planetary rovers to detect parts-per-billion concentrations of water. The sensors are made using nanomaterials like graphene and carbon nanotubes which are highly stable at extreme conditions. The sensors could help in search of life throughout the solar system.
