DESIGNED FOR PHOTOMETRIC STABILITY
The TESS mission will be based on Orbital's LEOStar-2 platform, a flexible, high-performance spacecraft for space and Earth science, remote sensing and other applications. LEOStar-2 can accommodate various instrument interfaces, deliver up to 2 kilowatt orbit average payload power, and support payloads up to 500 kilograms. Performance options include redundancy, propulsion capability, high data rate communications, and high-agility/high-accuracy pointing. TESS will be the eighth LEOStar-2 based spacecraft built for NASA. Previous missions include SORCE, GALEX, AIM, NuSTAR and OCO-2 spacecraft.
