Monitor Earth's ionosphere to better predict space weather
Designed to measure ultraviolet light in the upper atmosphere, TERRIERS was part of NASA's STudent Explorer Demonstration Initiative (STEDI), a program to demonstrate that small, low-cost, free-flying satellites could carry out high-quality space science. A collaboration led by the Center for Space Physics at Boston University, TERRIERS ran out of battery power after reaching orbit.
