Tim Williams, a research test pilot with NASA’s HyspIRI preparatory campaign, is helped into his pressure suit prior to an ER-2 aircraft flight, Marine Corps Air Station Kaneohe Bay, Feb. 2, 2018. The campaign’s goal is to gather environmental data from the Hawaiian Islands, such as coral reef health and volcanic activity, to ultimately pave the way for the deployment of a satellite sharing the same mission.
