Successful Wallops Flight Facility Launch: RockON/RockSAT-C (KOEHLER) – 24 June 2016

Credits: NASA / Patrick Black

NASA successfully launched a Terrier-Improved Orion suborbital sounding rocket carrying student experiments withthe RockOn/RockSat-C programs on June 24.

More than 200 middle school, high school, community college and university students and instructors participating inRocket Week at Wallops were on hand to witness the launch.

Through RockOn and RockSat-C students are learning and applying skills required to develop experiments forsuborbital rocket flight. In addition, high school educators through the Wallops Rocket Academy for Teachers(WRATS) are learning about applying rocketry basics in their curriculum.

The next launch from NASA’s Wallops Flight Facility is a Terrier-Improved Malemute suborbital sounding rocket currently scheduled for August 16. The rocket will be carrying the RockSat-X education payload.
