The Hydros instrument will be flown on the SpectrumAstro SA200HP spacecraft. The SA-200HP spacecraft is a robust platform that is capable for a variety of space missions. The SA-200HP is sized to support payloads using any smaller or medium class launch vehicle system, including Pegasus, Taurus, Athena, and Med-Lite Vehicles. The Hydros configuration of the spacecraft is close to the Coriolis that is currently in orbit.
