NASA astronaut Jessica Watkins served as the Ground IV for the JETT 5 field test and was the sole point of communications to NASA astronauts Andre Douglas and Kate Rubins who performed simulated moonwalks in the Arizona desert. JETT 5 was a week-long field test in the lunar-like landscape of San Francisco Volcanic Field near Flagstaff, Arizona while a team of flight controllers and scientists at Johnson monitor and guide their activities.
