CubeSat science payloadsCubeSat 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?
