Atlas V Rocket Launches with TDRS-M Satellite

The Tracking and Data Relay Satellite (TDRS) System is the solution to an early spaceflight problem: Officials on Earth had to rely on a pieced-together network of ground-based stations to communicate with spacecraft in orbit. The first TDRS satellite, TDRS-A, launched on space shuttle mission STS-6 in April 1983.

Today there are nine TDRS satellites in orbit at fixed points more than 22,000 miles above Earth’s surface. Two ground-based stations in White Sands, New Mexico, and one in Guam form the NASA Space Network. Together, the NASA Space Network and TDRS System provide a reliable high-bandwidth link to the International Space Station, the Hubble Space Telescope and a host of other orbiting missions.

The TDRS-M satellite that launched earlier today is the third and final in the system’s third generation of spacecraft. Once TDRS-M separates from the Centaur and begins its mission in space, it will go through a three- to four-month period of testing and calibration, followed by an additional three months of initial testing. At that time TDRS-M will be renamed TDRS-13, and it will either be put into service or stored in orbit until it’s needed by NASA’s Space Network.
