What do we do?• The mission of the SSU E/PO group is to develop
exciting formal and informal educational materials to inspire students in grades 5-14 to pursue STEM careers, to train teachers nation-wide in the classroom use of these materials, and to enhance science literacy for the general public.
• The S4 project is our newest curriculum development project, in partnership with AeroPAC, Endeavour Institute and NASA Dryden’s Aero Institute

Project Schedule• 2012-2013 Develop prototype payload
hardware, educator guide draft and test flights• July 8-13, 2013: Week-long teacher training
with NASA Dryden, including balloon tests and launch with ROC in Lucerne Dry Lakebed
• Academic year 2013/14: Teachers build payloads with their students
• Spring 2014: Student launches with local clubs

Snow Ranch April 2012
Initial tests of GPS in payload on Kevin Zack’s rocket
ARLISS/XPRS September 2012
• Payload tests included WiFi connectivity to 3000 feet - first use of 802.11g WiFi for telemetry
• AeroPAC’s Virtual Classroom used to transmit video Internet “lesson” to teachers and participants
