One of the newest NASA TDRS satellites, providing the high-bandwidth relay capacity needed for increasingly data-hungry missions. Modern Earth-observing satellites generate terabytes of data per day — TDRS-12 helps move that data to the scientists who need it. Positioned to complement the rest of the TDRS constellation for maximum coverage of low Earth orbit.
