Atlas V 511 | USSF-8
任务详情
USSF-8 will launch two identical Geosynchronous Space Situational Awareness Program (GSSAP) satellites GSSAP-5 and GSSAP-6 directly to a near-geosynchronous orbit approximately 36,000 km above the equator. Data from the GSSAP will uniquely contribute to timely and accurate orbital predictions, further enabling space flight safety including satellite collision avoidance. Unique to this mission is the first and only planned flight of the Atlas V 511 configuration.

描述
Atlas V is an expendable launch system in the Atlas rocket family. It was formerly operated by Lockheed Martin and is now operated by United Launch Alliance (ULA), a joint venture with Boeing. Each Atlas V rocket uses a Russian-built RD-180 engine burning kerosene and liquid oxygen to power its first stage and an American-built RL10 engine burning liquid hydrogen and liquid oxygen to power its Centaur upper stage. The RD-180 engines are provided by RD Amross, while Aerojet Rocketdyne provides both the RL10 engines and the strap-on boosters used in some configurations. The 511 version uses a 5m wide fairing, 1 solid rocket booster and one engine on the Centaur stage.
