This mission was a joint US - German - UK endeavor with the US
Charge Composition Explorer (CCE), an equatorial mission with
apogee close to 8 Re, with
Germany providing the Ion Release Module (IRM) with an
apogee close to 20 Re and the UK
providing the UK Subsatellite (UKS) in the same orbit as the IRM.
These spacecraft, stacked in the shroud of a Delta rocket, are
shown in Figure 1. The IRM spacecraft is
at the bottom of the stack. The UKS spacecraft served as the adapter
ring between the CCE on top and the IRM on the bottom. The
magnetometer was provided to the UK by UCLA. (D.J. Southwood
serves as P.I. of the magnetic field investigation).
Figure 2 shows the
launch of the spacecraft. The UKS spacecraft
provided data until January, 1985.
