TDRS 13 was built and launched to extend the useful life of NASA's constant communications infrastructure, supporting the astronauts around-the-clock aboard the International Space Station, supplying contact with the Hubble Space Telescope and transmitting the data from almost 40 science spacecraft studying Earth's environment and space. The TDRS network receives signals from vehicles like the space station flying at a mere 250 miles above Earth and routes the telemetry, voice, video and science information to a dedicated ground terminal for delivery to Houston. No matter where the space station is located at any given moment, TDRS has the outpost in sight for the two-way communications.
