ATLAS V ECHOSTAR XIX MISSION ATLAS V 431 An Atlas V 431 rocket will deliver EchoStar’s XIX satellite to geosyn- The Atlas V 431 configuration rocket, with three solid rocket boosters, chronous transfer orbit (GTO). The United Launch Alliance (ULA) provides the optimum performance to precisely deliver a range of Atlas V rocket is provided to Lockheed Martin Commercial Launch mission types. In service for more than ten years, the Atlas V 431 Services. Liftoff will occur from Space Launch Complex-41 at Cape configuration rocket has launched two commercial communications Canaveral Air Force Station, Florida. satellites where they provide global communications from geostationary orbit. EchoStar XIX will be the world’s highest capacity broadband satellite First Launch: Mar. 11, 2005 ® in orbit, dramatically increasing capacity for HughesNet high-speed Launches to date: 2 satellite Internet service to homes and businesses in North America. This large, multi-spot beam Ka-band satellite, based on the powerful Performance to GTO: 7,700 kg (16,970 lb) SSL 1300 platform, will be stationed at 97.1 degrees West longitude. Performance to LEO-Reference: 15,260 kg (33,660 lb) Building from their experience on the highly successful EchoStar XVII broadband satellite, SSL and Hughes collaboratively engineered the specific design details of this payload for optimum performance.

Payload Fairing (PLF) The EchoStar XIX satellite is encapsulated in the 4-m (14-ft) diameter extra extend- ed payload fairing (XEPF). The XEPF is a bisector (two-piece shell) fairing consisting of aluminum skin/stringer construction with vertical split-line longerons. The vehicle’s height with the PLF is approximately 194 ft.

Centaur The Centaur second stage is 10 ft in diameter and 41.5 ft in length. Its propellant tanks are constructed of pressure-stabilized, corrosion resistant stainless steel. Centaur is a liquid hydrogen/liquid oxygen- (cryogenic-) fueled vehicle. It uses a single RL10C-1 engine producing 22,900 lbf of thrust. The cryogenic tanks are insulated with a combination of helium-purged insulation blankets, radiation shields, and spray-on foam insulation (SOFI). The Centaur forward adapter (CFA) provides the structural mountings for the fault-tolerant avionics system and the structural and electrical interfaces with the spacecraft. Booster MISSION OVERVIEW The Atlas V booster is 12.5 ft in diameter and 106.5 ft in length. The booster’s tanks are structurally rigid and constructed of isogrid aluminum barrels, spun-formed aluminum domes, and intertank skirts. Atlas booster propulsion is provided by the RD-180 engine system (a single engine with two thrust chambers). The RD-180 burns RP-1 (Rocket Propellant-1 or highly purified kerosene) and liquid oxygen, and delivers 860,200 lb of thrust at sea level. Three solid rocket boosters (SRB) With more than a century of combined heritage, United Launch Alliance – 68th Atlas V Launch generate the additional power required at liftoff, with each SRB providing 348,500 is the nation’s most experienced and reliable launch service provider. – 115th ULA Launch lb of thrust. The Atlas V booster is controlled by the Centaur avionics system, which ULA has successfully delivered more than 110 satellites to orbit that provides guidance, flight control, and vehicle sequencing functions during the boost- provide critical capabilities for troops in the field, aid meteorologists in er and Centaur phases of flight. tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.
