Cape Canaveral LC13

First Launch: 1958-08-02. Last Launch: 1978-04-07. Number: 51 . Longitude: -80.54 deg. Latitude: 28.49 deg.

The complex was built for the Atlas ballistic missile program. Launch sites 11 to 14 were accepted between August 1957 and mid-April 1958. Complex 13 supported its first Atlas launch on 2 August 1958. After its final Atlas missile launch on 13 February 1962, Complex 13 was converted into an Atlas /Agena launch complex. Three pairs of VELA satellites were launched from Complex 13 before the site was turned over to NASA in 1966. Following a series of civilian Atlas /Agena missions, Complex 13 was returned to the Air Force in March 1968. The site supported 11 Atlas /Agena space flights for the Defense Department between 6 August 1968 and 7 April 1978. In all, Complex 13 supported 51 ATLAS and Atlas /Agena launches. Complex 13 was deactivated in April 1978. Complex 14 and the gantry on Complex 13 were declared national historic landmarks in April 1984.

• Research and development test - . Nation: USA. Agency: USAF. Apogee: 900 km (550 mi).

  The first successful flight test of a Series B Atlas missile. This was also the first successful staging of a long-range missile. (AF Ballistic Missiles Program Status Report.) Flight test missile 4B was the first Atlas Series B missile to be launched successfully and the first ICBM to complete staging. Its 2,500-mile powered flight was the first time that the MA-1 propulsion cluster operated for the planned duration of flight. Second full-powered flight of USAF Atlas ICBM traveled 2,500 miles with radio-inertial guidance, fully successful.

  The first Atlas D model flight test missile (3D) had to be destroyed 36 seconds into flight due to a severe engine malfunction and explosions. In addition to other changes, the D series replaced the MA-1 engine package with the Rocketdyne MA-2. The booster engines in the MA-2 produced 309,000 pounds of thrust versus 300,000 pounds for the MA-1. Sustainer engine thrust remained 57,000 pounds. With verniers, total thrust for the MA-2 was 368,000 pounds compared to 357,000 for the MA-1 engine package.

  Lunar Orbiter I was launched from Cape Kennedy Launch Complex 13 at 3:26 p.m. EDT August 10 to photograph possible Apollo landing sites from lunar orbit. The Atlas-Agena D launch vehicle injected the spacecraft into its planned 90-hour trajectory to the moon. A midcourse correction maneuver was made at 8 p.m. the next day; a planned second midcourse maneuver was not necessary. A faultless deboost maneuver on August 14 achieved the desired initial elliptic orbit around the moon, and one week later the spacecraft was commanded to make a transfer maneuver to place it in a final close-in elliptic orbit of the moon.

  During the spacecraft's stay in the final close-in orbit, the gravitational fields of the earth and the moon were expected to influence the orbital elements. The influence was verified by spacecraft tracking data, which showed that the perilune altitude varied with time. From an initial perilune altitude of 58 kilometers, the perilune decreased to 49 kilometers. At this time an orbit adjustment maneuver began an increase in the altitude, which was expected to reach a maximum after three months and then begin to decrease again. The spacecraft was expected to impact on the lunar surface about six months after the orbit adjustment.

  During the photo-acquisition phase of the flight, August 18 to 29, Lunar Orbiter I photographed the 9 selected primary potential Apollo landing sites, including the one in which Surveyor I landed; 7 other potential Apollo landing sites; the east limb of the moon; and 11 areas on the far side of the moon. Lunar Orbiter I also took photos of the earth, giving man the first view of the earth from the vicinity of the moon (this particular view has been widely publicized). A total of 207 frames (sets of medium- and high-resolution pictures) were taken, 38 while the spacecraft was in initial orbit, the remainder while it was in the final close-in orbit. Lunar Orbiter I achieved its mission objectives, and, with the exception of the high-resolution camera, the performance of the photo subsystem and other spacecraft subsystems was outstanding. At the completion of the photo readouts, the spacecraft had responded to about 5,000 discrete commands from the earth and had made about 700 maneuvers.

  Photographs obtained during the mission were assessed and screened by representatives of the Lunar Orbiter Project Office, U.S. Geological Survey, DOD mapping agencies, MSC, and Jet Propulsion Laboratory. The spacecraft was deliberately crashed into moon after the mission was completed.

• Lunar Orbiter 2 - . Payload: Lunar Orbiter B. Mass: 390 kg (850 lb). Nation: USA. Agency: NASA Langley. Class: Moon. Type: Lunar probe. Spacecraft: Lunar Orbiter. Decay Date: 1967-10-11 . USAF Sat Cat: 2534 . COSPAR: 1966-100A.

  Lunar Orbiter II was launched at 6:21 p.m. EST from Launch Complex 13 at Cape Kennedy, to photograph possible landing sites on the moon for the Apollo program. The Atlas-Agena D booster placed the spacecraft in an earth-parking orbit and, after a 14-minute coast, injected it into its 94-hour trajectory toward the moon. A midcourse correction maneuver on November 8 increased the velocity from 3,051 to 3,133 kilometers per hour. At that time the spacecraft was 265,485 kilometers from the earth.

  The spacecraft executed a deboost maneuver at 3:26 p.m., November 10, while 352,370 kilometers from the earth and 1,260 kilometers from the moon and traveling at a speed of 5,028 kilometers per hour. The maneuver permitted the lunar gravitational field to pull the spacecraft into the planned initial orbit around the moon. On November 15, a micrometeoroid hit was detected by one of the 20 thin-walled pressurized sensors.

  The spacecraft was transferred into its final close-in orbit around the moon at 5:58 p.m. November 15 and the photo-acquisition phase of Lunar Orbiter II's mission began November 18. Thirteen selected primary potential landing sites and a number of secondary sites were to be photographed. By the morning of November 25, the spacecraft had taken 208 of the 211 photographs planned and pictures of all 13 selected potential landing sites. It also made 205 attitude change maneuvers and responded to 2,421 commands.

  The status report of the Lunar Orbiter II mission as of November 28 indicated that the first phase of the photographic mission was completed when the final photo was taken on the afternoon of November 25. On November 26, the developing web was cut with a hot wire in response to a command from the earth. Failure to achieve the cut would have prevented the final readout of all 211 photos. Readout began immediately after the cut was made. One day early, December 6, the readout terminated when a transmitter failed, and three medium-resolution and two high-resolution photos of primary site 1 were lost. Full low-resolution coverage of the site had been provided, however, and other data continued to be transmitted. Three meteoroid hits had been detected.

  Lunar Orbiter V was launched from the Eastern Test Range at 6:33 p.m. EDT August 1. The Deep Space Net Tracking Station at Woomera, Australia, acquired the spacecraft about 50 minutes after liftoff. Signals indicated that all systems were performing normally and that temperatures were within acceptable limits. At 12:48 p.m. EDT August 5, Lunar Orbiter V executed a deboost maneuver that placed it in orbit around the moon. The spacecraft took its first photograph of the moon at 7:22 a.m. EDT August 6. Before it landed on the lunar surface on January 31, 1968, Lunar Orbiter V had photographed 23 previously unphotographed areas of the moon's far side, the first photo of the full earth, 36 sites of scientific interest, and 5 Apollo sites for a total of 425 photos.

By April 1971, spacecraft perigee had increased to 26,400 km and inclination had increased to 54 deg. The spacecraft attitude control failed on August 6, 1971, after 41 months of normal operation. The spacecraft was placed in a standby status on October 8, 1971. Four experiments (Meyer, Blamont, Thomas, and Simpson) were reactivated for the period from June 1 to July 13, 1972, after which all operational support terminated. Spacecraft orbit parameters changed significantly over the spacecraft life.
