RockSat-W RockOn!
2.0 Workshop Payload Overview The mission of RockOn is to teach university faculty and students the basics of rocket payload construction and integration. RockOn also acts as the first step in the RockSat series where workshop participants return the following year to design, build, test, and fly their own experiment. The RockOn payload is designed to capture and record 3-axis accelerations, pressure, temperature, and radiation counts over the course of the mission.
