Associated Launch Sites
Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...
Cape Canaveral LC17B Delta launch complex. Part of a dual launch pad complex built for the Thor ballistic missile program in 1956. Upgraded over the decades for use with Thor, Delta, Delta II, and Delta III launch vehicles, it remained in use for over half a century. More...

Mass: 840 kg (1,850 lb). Nation: USA. Agency: NASA Greenbelt. Class: Astronomy. Type: Infrared astronomy satellite. Spacecraft: MAP. USAF Sat Cat: 26859 . COSPAR: 2001-027A. Apogee: 379,553 km (235,842 mi). Perigee: 4,704 km (2,922 mi). Inclination: 27.8000 deg. Period: 14,669.70 min. NASA's Microwave Anisotropy Probe (MAP) was placed in a 167 x 204 km x 28.8 deg parking orbit at 1958 GMT. At 2104 GMT the second stage ignited again for a 4 second burn, raising the orbit to around 181 x 308 km; the third stage spun up and ignited at 2108 GMT, accelerating MAP to a highly elliptical orbit of 182 x 292,492 km x 28.7 deg. MAP used on-board fuel to tweak the orbit and make a lunar flyby at fourth apogee on July 30, arriving at the L2 Earth-Moon Lagrangian point 1.5 million km from Earth three months later. From L2, MAP was to measure fluctuations in the cosmic 3 Kelvin microwave background with the degree of precision required to answer questions about the big bang and the total mass and fate of the universe. By July 22 the MAP probe was in a 4055 x 355,935 km x 28.0 deg orbit. It flew past the Moon on July 30 at 1639 GMT at an altitude of 5200 km above the lunar surface.
