Associated Launch Sites
  • White Sands White Sands Missile Range occupies an area 160 x 65 km in the Tularosa Basin of southern New Mexico, across the Sacramento Mountain range from Roswell. In the 1930's, Robert Goddard, after surveying weather conditions and population densities, had selected Roswell for his pioneering rocket tests. White Sands, a true desert area, was even more unpopulated than Roswell. German advances in rocketry during World War II impelled the US Army to begin programs to exploit this technology. The White Sands Proving Ground was established for testing German and American long-range rockets on 9 July 1945. Seven days later the first atomic bomb was exploded at Trinity Site, near the north boundary of the range. The first launch of a Tiny Tim rocket was on 26 September 1945. On 11 October a Tiny Tim boosted a WAC Corporal rocket from the tower. This was the first use of Launch Complex 33, later to be used for V-2, Nike, Viking, Corporal, Lance and Multiple Launch Rocket System testing. More...
  • White Sands LC36 Terrier, Redstone, Nike, Little Joe II, Honest John, Black Brant, Storm, Aries, Apollo LES launch complex. Originally designated Army Launch Area 2, LC36 was later a LC36 was a NASA facility that supported tests of the Apollo Launch Escape System. It was also used to launch NASA sounding rocket missions. The complex included a blockhouse, launch control equipment, and launchers with environmental shelters. These launchers included:
    • An 11-m rail with 3600 kg capacity
    • A 15-m rail with 11,000 kg capacity
    • A 50-m tower with 3600 kg capacity
    • A 1.2-m diameter stool with 23,000 kg capacity
    • A 9-m rail with 7000 kg capacity.

1964 December 8 - . 15:00 GMT - . Launch Site: White Sands. Launch Complex: White Sands LC36. LV Family: Little Joe II. Launch Vehicle: Little Joe II 4-2-0. LV Configuration: Little Joe II-4-2-0 LJII-3 (12-51-1).
  • A-002 / BP-23 Spacecraft test - . Nation: USA. Agency: NASA. Apogee: 5.00 km (3.10 mi). Boilerplate 23, Mission A-002, was successfully launched from WSMR by a Little Joe II launch vehicle. The test was to demonstrate satisfactory launch escape vehicle performance utilizing the canard subsystem and boost protective cover, and to verify the abort capability in the maximum dynamic pressure region with conditions approximating emergency detection subsystem limits.
