At Launch Complex 36 A Cape Canaveral Air Force Station nears the top of the launch tower.

At Launch Complex 36-A, Cape Canaveral Air Force Station, a Lockheed Martin Atlas Centaur IIA (AC-144) rocket nears the top of the launch tower. The rocket will be used in the launch of TDRS-J, scheduled for Nov. 20. The third in a series of telemetry satellites, TDRS-J will help replenish the current constellation of geosynchronous TDRS satellites. The TDRS System is the primary source of space-to-ground voice, data and telemetry for the Space Shuttle. It also provides communications with the International Space Station and scientific spacecraft in low-Earth orbit such as the Hubble Space Telescope. This new advanced series of satellites will extend the availability of TDRS communications services until about 2017.
