A United Launch Alliance Atlas 5 rocket, designated AV-075, will launch the TDRS M communications and data relay satellite for NASA. The Tracking and Data Relay Satellite System (TDRSS) connects mission control with the International Space Station and other orbiting satellites. The rocket will fly in the 401 vehicle configuration with a four-meter fairing, no solid rocket boosters and a single-engine Centaur upper stage.

LAUNCH WINDOW: 8:04 A.M. – 8:44 A.M.

Best viewing sites for the general public include: anywhere along the shores of the Indian River in Titusville, or any of the beaches south of Port Canaveral along the Space Coast. 

**Launch date, time, and viewing opportunities are subject to change. Launches can be affected by technical and mechanical issues as well as range operations and weather, either in advance or at the last minute.

The launch window is the time period during which the rocket must be launched in order to reach its intended target. If the rocket is not launched during this time period, the launch will be rescheduled for the next available window.

LAUNCH VEHICLE:

The Atlas V rocket was introduced by United Launch Alliance (ULA) in August 2002. The Atlas V was developed to provide launch services to the U.S. government and is a part of the Atlas program which in total has logged more than 600 launches to date. Since their debut, Atlas V vehicles have achieved 100 percent mission success in launches from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida and Space Launch Complex-3E at Vandenberg Air Force Base, California. The rocket uses a standard common core booster™ (CCB), up to five strap-on solid rocket boosters (SRB), an upper-stage Centaur in either the Single-Engine Centaur (SEC) or the Dual-Engine Centaur (DEC) configuration, and one of several payload fairings (PLF). The OA-7 mission rocket will fly in 401 vehicle configuration with a four-meter fairing, no solid rocket boosters and a single-engine Centaur upper stage.
