NASA technology played an important part in the Mt. St. Helen's aftermath, not only in scientific studies, but also in disaster assessment and relief operations. A particular problem was maintaining communications with rescue ground crews and evacuation helicopters operating in the smoke-obscured area. The key element came from NASA's ATS-3 satellite, which is capable of beaming to and receiving signals from small, simple antennas on the ground, and a communications jeep developed by the Air Force. NASA also helped to assess the environmental impact of the eruption. A specially-instrumented aircraft operated by several NASA Centers took samples of the volcanic material at various points over the U.S. and tracked the volcano's plume. A NASA instrumented balloon penetrated the plume and the Stratospheric Aerosol and Gas Experiment Satellite tracked the global spread of the volcanic "veil."
