Small Payloads for Investigation of Disturbances in Electrojet by Rockets

SPIDER is developed under the new Swedish national balloon and rocket programme. SPIDER will carry a payload of ten (10) free flying units (FFU) to be released from the main payload at ~65 km. The FFU’s will deploy probes on wire booms to measure turbulences in the auroral electrojet between 95 km and 115 km.

The research will be carried out using a single stage S30 in early winter 2016.

The payload will be launched in this period into geo-magnetically active conditions to study the auroral electrojet.
The FFU’s will be deployed from a spinning main payload and use their residual spin after deployment to extract their wire booms. All FFU’s are self-sufficient and will be recovered by helicopter for data extraction after landing with their own parachute system.

SSC is contracted for the mission

SSC is in addition providing

  • Project management
  • Service systems
  • System integration and testing
  • Launch service (Eurolaunch)
  • Operations

P.I. is Ass. Prof. Nickolay Ivchenko, Department of Space and Plasma
Physics at the Royal Institute of Technology (KTH)

The FFU’s and their ejection system are developed by KTH
