ICI-5 consists of one payload. Andoya Space Center (ASC) was responsible for the overall management of the mission and provided the ICI-5 payload via the University of Oslo, while NASA provided the launch vehicle. 

The cusp is a source of local perturbations in the ionosphere and also a source of ionospheric disturbances that propagate all the way to mid and low latitudes. The ICI payload contained a 4D space module that was designed to deploy 6 daughter payloads and the main payload contained an instrumentation suite provided by a multinational science team that includes researchers from Norway, United States, and Canada.

The main objectives of ICI-5 were:

- to investigate plasma instability modes during the formation of polar cap patch (high plasma density + precipitation)

- conduct 3D in-situ measurements to differentiate between wave and turbulence structures

The Principal Investigator was Dr. Moen/University of Oslo.
