Ben Feist, software engineer on the Extravehicular Activity Mission System Software (EMSS) team, uses the suite of software he and other members of the Astromaterials Research and Exploration Science (ARES) division at NASA's Johnson Space Center in Houston developed to plan and monitor spacewalks. The JETT 5 field test was the first time this software was fully integrated into a simulated mission, supporting both science and mission control operations. JETT 5 was a week-long field test conducted in the lunar-like landscape of the San Francisco Volcanic Field near Flagstaff, Arizona, with a team of flight controllers and scientists at Johnson monitoring and guiding the activities.
