2. Overview Student satellite programs Student satellite programs Commercial – off the shelf satellites Commercial – off the shelf satellites Training students to do satellites Training students to do satellites Future student space programs Future student space programs Summary Summary

3. Leave Message for Today Student satellite program are more mature than you may expect and will continue to advance rapidly. Collaboration is the fuel of success. Small Satellite Missions: Educate students in engineering & science Produce innovation Tests new technology Are doing real science at low costs

34. Message to you today: NSF – Universities Make a Deal Today!

35. Thanks

36. CubeSat science payloads Instrument component space qualification Common secondary payload on all CubeSats  Radiation sensor  Magnetometer Tethered satellites for constellations Tethers for spaced sensors How do we match scientists to spacecraft developers? Have universities test spacecraft bus on sounding rocket with science instruments?
