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...

Thor DSV-2F Chronology


1963 September 18 - . 09:39 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17B. LV Family: Delta. Launch Vehicle: Thor DSV-2F. LV Configuration: Thor DSV-2F 232.
  • ASSET 1 re-entry vehicle test flight - . Nation: USA. Agency: USAF. Apogee: 56 km (34 mi). Suborbital test of small scale spaceplane model to test materials for the X-20 Dynasoar. Aero-thermodynamic structural test vehicle (ASV) for heat shield tests. Booster flew to peak altitude of 62 km, then pitched down, driving the spacecraft to separation at 59 km and 4,906 m/s. The spacecraft was sited under its parachute in the recovery zone at Ascension Island, but the flotation bag broke and it sank into the Atlantic.

1964 October 29 - . 03:35 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17B. LV Family: Delta. Launch Vehicle: Thor DSV-2F. LV Configuration: Thor DSV-2F 260.
  • ASSET 4 re-entry vehicle test flight - . Nation: USA. Agency: USAF. Apogee: 50 km (31 mi). Suborbital test of small scale spaceplane model to test structural concepts for the X-20 Dynasoar. Aero-environmental test vehicle (AEV) to test aerodynamic properties of flexing outer skin with corrugated columbium panel. Reached 4,000 m/s at 50.6 km altitude before being released from launch vehicle. Telemetry received for 900 seconds until spaceplane had reached Mach 2 1200 km downrange. It then became unstable and crashed into the Atlantic. Recovery was not planned.

1964 December 9 - . 02:00 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17B. LV Family: Delta. Launch Vehicle: Thor DSV-2F. LV Configuration: Thor DSV-2F 247.
  • ASSET 5 re-entry vehicle test flight - . Nation: USA. Agency: USAF. Apogee: 50 km (31 mi). Suborbital test of small scale spaceplane model to test structural concepts for the X-20 Dynasoar. Aero-environmental test vehicle (AEV) to test aerodynamic properties of flexing outer skin with corrugated columbium panel. Reached 4,000 m/s at 53.2 km altitude before being released from launch vehicle. Telemetry received for 900 seconds until spaceplane had reached Mach 2 1200 km downrange. It then became unstable and crashed into the Atlantic. Recovery was not planned.
