The National Aeronautics and Space Administration expects to fund up to seven U.S. scientists in cooperative research in the Soviet Intercosmos Council ACTIVE scientific satellite mission. Scientists proposing research must be in the U.S. or its territories, and proposals must be for studies or services specific to the ACTIVE objectives.

ACTIVE aims to investigate very-low-frequency (VLF) radiowave propagation and wave-particle interactions in the magnetosphere using a 10-kW VLF transmitter with a large loop antenna on a satellite in low-Earth orbit. Effects occurring in the ionospheric plasma near the transmitter will be studied with instruments on the ACTIVE satellite and on a co-orbiting maneuverable subsatellite. The waves and their effects will also be observed with instruments on the ground and on other satellites. ACTIVE objectives are similar to those of the VLF part of NASA's Waves in Space Plasmas (WISP) program.
