The Tomographic Experiment using Radiative Recombinative Ionospheric EUV and Radio Sources (TERRIERS) project is the second satellite in NASA's Student Explorer Demonstration Initiative (STEDI) program. STEDI, managed for NASA by USRA, is a pilot program to demonstrate that high-quality space science can be carried out with small, low-cost free-flying satellites on a time scale of two years from go-ahead to launch.

The Multiple Paths, Beyond-Line-of-Sight Communications (MUBLCOM) satellite, built for the Pentagon's Defense Advanced Research Projects Agency. Its mission was to demonstrate a capability to provide space-based digital voice and data communications to combat forces or commercial users that were previously considered out of range of standard radio communications systems.
