With the recent advances in low-power miniaturized electronics, sensors, and wireless technology, powerful new ways are available for collecting multipoint measurements in Geospace and the Upper Atmosphere. At our undergraduate university, three nanosatellites were developed that demonstrate the exceptional capability of nanosatellites for research and education. TUSat 1 was a dual CubeSat (1.8 kg) that included 1) a novel tether system for stabilization and electrodynamics studies, 2) a plasma probe on a boom, 3) a 3-axis magnetometer, 4) a VLF receiver, and 5) a 56 kB spread spectrum (902-928 MHz) data/E-mail communication system with an amateur radio beacon. The Thunderstorm Effects in Space and Technology (TEST) nanosatellite was a partnership between Taylor University and the University of Illinois (UI) and was part of the AFOSR nanosat program. TEST was a 27 CubeSat module design that included 1) 3-axis stabilization and power system, 2) plasma probe, 3) UI photometer and spectrometer, 4) transient photometer, 5) dual energetic particle spectrometers, 6) VLF receiver, 7) educational pods, and 8) spread spectrum and amateur radio communication. Recently we participated in the AFOSR Boston University nanosatellite (BUSat) providing instruments and a communication system. Nanosatellites provide a new way of advancing space science since they 1) foster creativity, 2) make multipoint measurements (improve global math models and understanding), and 3) study the unexplored lower thermosphere space environment and ionosphere and distant interplanetary objects. The low-cost and state-of-the- art technology associated with constellations of nanosatelites make them ideal for Low Earth Orbit (LEO) altitudes (120 - 500 km) where paucity of data and the orbit decay rate are high. Orbital debris pollution is also relatively unimportant in low LEO orbits. For nanosats to be successful a rigorous program needs to be established for testing, calibration, and quality assurance. The High-Altitude Research Platform (HARP) has now launched over 200 balloon flights with 100% real-time telemetry and recovery at Taylor University. The HALO program demonstrated the reliability of an intra-balloon mesh network by simultaneously launching 13 payloads separated by over 500 miles at altitudes of 25 km. The educational outcomes from nanosatellite experiments are strong for STEM education and directing students professionally into space science.
