Cosmic Penguin
Geek Penguin in GTO
The coming of a new year comes, of course, with new satellites. And for the second consecutive year the versatile but aging fleet of NASA's Tracking and Data Relay Satellites (TDRS) is receiving a new member! TDRS-L is poised to become the 12th satellite of the program, serving a large number of users for NASA (from ISS to Hubble to Earth observation satellites), the DoD and even launch service providers (ULA itself, Sea Launch, even SpaceX).
Build on the tried and true Boeing BSS 601 satellite bus, the satellite, like its siblings TDRS-K and M, is an improved variant of the older TDRS-H series, with its antenna beaming power and on board data processing abilities increased. The satellite will initially be stationed at 49 degrees West (over the Atlantic Ocean) for check out and back up duties. Another one satellite, TDRS-M, will be launched in late 2015.
The Atlas V rocket (flying in the basic 401 configuration) will be launched at 9:05 pm EST (02:05 UTC) from Cape Canaveral's SLC-41. It will be deployed into the planned transfer orbit 1 hour 46 minutes after launch.

This is the 43th operational flight of the Atlas V rocket and the 20th to fly in the 401 configuration with no solid rocket boosters and the 4 meter diameter fairing.

Mission Description:
NASA established the TDRS project in 1973 to provide around-the-clock communications to the agency's most critical missions in low Earth orbit. The TDRS Project is providing follow-on and replacement spacecraft necessary to maintain and expand the Space Network.

[/table]Launch Vehicle:
The Atlas V 401 consists of a single Atlas V booster stage, the Centaur upper stage, and a 4-m diameter payload fairing (PLF). 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. The Atlas V booster is controlled by the Centaur avionics system, which provides guidance, flight control, and vehicle sequencing functions during the booster and Centaur phases of flight. The Centaur upper 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 RL10A-4-2 engine producing 22,300 lb 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. The TDRS-K mission is encapsulated in the 4-m (14-ft) diameter extended payload fairing (EPF). The EPF is a bisector (two-piece shell) fairing consisting of aluminum skin/stringer construction with vertical split-line longerons. The vehicle’s height with the EPF is approximately 192 ft.
