Early concept art for the explorer.
Innovative Interstellar Explorer was a NASA "Vision Mission" study funded by NASA following a proposal under NRA-03-OSS-01 on 11 September 2003. This study focused on the elusive quest to reach and measure the interstellar medium, the region outside the influence of the nearest star, the Sun.[1] It proposes to use a radioisotope thermal generator to power ion thrusters.[1] The project is a study of a proposed interstellar precursor mission that would probe the nearby interstellar medium and measure the properties of magnetic fields and cosmic rays and their effects on a craft leaving the Solar System.[2] Mission launch plans analyzed direct, one planet, multi-planet, and upper-stage trades.[3]
A variety of plans were proposed, including using launch windows (not counting backups) for a Jupiter assist in 2014, 2026, 2038, and 2050
