Summary
The TERRIERS satellite, also known by its alternative name TERRIERS, is an atmospheric research satellite designed and operated by GSFC (Goddard Space Flight Center). Launched on May 18, 1999, from the Wallops Flight Facility (WRAS) using a Pegasus XL/HAPS launch vehicle, it has a configuration known as HETE-Bus, featuring spin stabilization. The satellite is equipped with instruments including GISSMO, TESS, photometers, and a radio beacon for its mission purposes. It measures 1 meter in length, 0.5 meters in diameter, and has a span of 1.1 meters. Its dry mass at launch was 125 kilograms, which was also its launch mass. The satellite is powered by fixed solar arrays and batteries. With a planned lifetime of one year, it features a box shape with an RCS value of 0.463 but lacks specific details on its attitude determination and control system (ADCS) or color. Its primary mission involves atmospheric research, and the spacecraft was manufactured by AEROA.
