Phase Two of WAS is a six-day summer residency experience for 160 students. Selection will be competitive and centers around performance in Phase One of WAS. In each residency session, 40 Scholars are selected to work cooperatively to plan a human mission to Mars with support from professional engineers/scientists, university students, and certified educators. Each session also includes briefings from aerospace professionals, tours of engineering facilities, and hands-on engineering challenges involving model rocketry, robotics, landing devices, and payload lofting. The daily schedule is full, and the students will lodge at a local hotel under the supervision of certificated teachers. Travel, lodging, and meal expenses are provided to participating students and teachers thanks to the WAS Foundation.
