Injun-3ISEE-3

This page contains reference images for Injun, SolRad (Solar Radiation), GEOS (Geodetic Earth Orbiting Satellite (GEOS-1 and 2) or Geodynamics Experimental Ocean Satellite (GEOS-3)), and ISEE (International Sun-Earth Explorer) / ICE (International Cometary Explorer) series satellites. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page.

These series are related to the Explorer series because some of the satellites had Explorer names and numbers as well. In particular, the following satellite names and numbers were synonymous:
