Pad 5 supported its first Jupiter A launch on 19 July 1956. In addition to Redstone and Jupiter launches, the complex supported Explorer and Pioneer missions and all six Redstone /Mercury suborbital flights. On 31 January 1964, Complexes 5 and 6 were reassigned to become part of the USAF Space Museum.

• 1956 July 19 08:45 - Test mission Launch Vehicle: Redstone. ST-80 malfunction at theta switch operation - 310 sec.. Redstone CC-13 Apogee: 90 km (55 mi). Range: 264 km (164 mi). CC-13 was launched at 0345 hours EST from AMR. The flight was successful. The actual range was 142.457 nm; .780 nm over the intended impact point. This was the first Chrysler fabricated and assembled missile. Missed aimpoint by 1,071 m.

• 1956 September 20 06:45 - Jupiter C re-entry vehicle test flight Launch Vehicle: Redstone. Early cut-off due to human error in tanking .. Redstone RS-27 Apogee: 1,097 km (681 mi). Range: 5,380 km (3,340 mi). First Jupiter C (a three-stage ABMA-JPL Redstone missile) was launched at Cape Canaveral, Fla., attained an altitude of 1096 km and traveled 5,300 km downrange. The first three-stage re-entry missile, was fired at 0145 hours EST from AMR. This missile attained an estimated range of 3,335 ST miles, an altitude of 682 ST miles, and reached Mach 18 velocity. The primary objective of the firing was the propulsion and separation tart of a multi-stage vehicle. The missile was a four-stage configuration with the last stage inactive. The first stage was an elongated Redstone missile, the second and third stages were up of 11 and 3 six-inch scaled SERGEANT rockets, respectively. The payload consisted of approximately 20 pounds of instrumentation attached to the inactive fourth stage. The flight was successful and the sequence of operations occurred as programmed. This vehicle could have obtained sufficient velocity to place it in orbit, if the last stage had been activated. First deep penetration of space. Serial number coding for early Redstones and related vehicles used the following substitution cipher: 1234567890 = HUNTSVILLEX

• 1957 March 1 21:51 - Research and development launch Launch Vehicle: Jupiter. Missile break-up attributed to overheating in the tail section.. Jupiter AM-1A Apogee: 14 km (8 mi). The first Jupiter flight was fired at 1651 hours EST from AMR. The missile achieved a 48,000 foot altitude. Flight terminated at 7.4 seconds because of missile break-up. Failure was attributed to overheating in the tail section. The trajectory to this point was as predicted.

• 1957 April 26 20:12 - Research and development launch Launch Vehicle: Jupiter. Failure. Jupiter AM-1B Apogee: 18 km (11 mi). Fired from AMR at 1512 hours EST to test the design version of the airframe and rocket engine. The flight terminated at 93 seconds because of propellant slosh. The missile achieved an altitude of 60,000 feet. The flight was partially successful.

• 1957 May 31 18:08 - Research and development launch Launch Vehicle: Jupiter. Jupiter AM-1 Apogee: 500 km (310 mi). Range: 2,127 km (1,321 mi). Army Jupiter IRBM was fired 1,500 miles, limit of its designed range, and to an altitude of 250-300 miles, the first successful launching of an IRBM. Fired from AMR at 1308 hours EST to test the range capability and performance of rocket engine and control system. Although the missile was 253 nm short of its estimated 1,400 nm impact point, this was the first successful flight of the Jupiter. All phases of the test were successful during this first firing of the IRBM in the western world

• 1958 March 26 17:38 - Explorer 3 Launch Vehicle: Redstone. Redstone RS-24 Apogee: 2,799 km (1,739 mi). Radiation, micrometeoroid data.

Redstone RS/CC-49 NASA¾with the Army as executive agent¾attempted to launch a 12-foot-diameter inflatable satellite of micro-thin plastic covered with aluminum foil known as BEACON. Launched from AMR by a Juno I¾a modified Redstone, the payload prematurely separated prior to booster burnout.

• 1958 December 6 05:44 - Pioneer 3 Launch Vehicle: Jupiter. First Stage shut down too early. Partial Failure.. Jupiter AM-11 Failed to reach moon; provided radiation data. Pioneer III, the third U.S.-IGY intended lunar probe under the direction of NASA with the Army acting as executive agent, was launched from the Atlantic Missile Range by a Juno II rocket. The primary objective, to place the 12.95 pound scientific payload in the vicinity of the moon, failed. Pioneer III reached an altitude of approximately 70,000 miles and revealed that the earth's radiation belt comprised at least two distinct bands.

• 1959 January 22 00:10 - Tactical test mission Launch Vehicle: Jupiter. Jupiter CM-21 Apogee: 500 km (310 mi). Range: 2,415 km (1,500 mi). Tactical Test. The first Chrysler production qualification missile was fired from AMR at 1910 hours EST. The nose cone impacted in the pre-selected target area at a range of 1,302 nm. Miss distance was 3 nm over and 1 nm to the left of the target. The overshoot was caused by failure of the vernier engine to cut off high resistance of the squib firing circuit. Primary missions were successfully accomplished.

• 1959 March 3 05:10 - Pioneer 4 Launch Vehicle: Jupiter. Jupiter AM-14 The fourth U.S.-IGY lunar probe effort, Pioneer IV, a joint project of the Army Ballistic Missile Agency and Jet Propulsion Laboratory under the direction of NASA, was launched by a Juno II rocket from the Atlantic Missile Range. Intended to impact on the lunar surface, Pioneer IV achieved earth-moon trajectory, passing within 60,200 km of the moon before going into permanent orbit around the sun.

• 1959 May 14 05:52 - Research and development launch Launch Vehicle: Jupiter. Jupiter AM-17 Apogee: 88 km (54 mi). Fired from AMR at 0052 hours EST to test impact accuracy. This shot may be considered as having hit the target. The impact was: .26 nm over and 0.4 nm to the left of the predicted point of impact. Accuracy of the MILS Network was approximated at plus-or-minus 0.25 nm. All primary and secondary missions were accomplished except for photographic recording of the second separation. This could not be accomplished because of the firing date.

• 1959 July 16 17:37 - Explorer S-1 Launch Vehicle: Jupiter. Control lost after 5.5 sec. Destroyed by range safety.. Jupiter AM-16

• 1959 August 27 01:30 - Short range research and development mission Launch Vehicle: Jupiter. Jupiter AM-19 Apogee: 500 km (310 mi). Range: 556 km (345 mi). A short range (300 nm) IRBM, was fired from AMR at 2030 hours EST. The nose cone impacted 0.03 nm short and, 0.22 nm to the right, of the intended target. This was the first Jupiter missile to be programmed for a short range flight. All primary and secondary missions were accomplished.

• 1959 October 13 15:30 - Explorer 7 Launch Vehicle: Jupiter. Jupiter AM-19A Apogee: 857 km (532 mi). Spacecraft engaged in research and exploration of the upper atmosphere or outer space. Returned magnetic field and solar flare data.

• 1960 November 21 14:00 - Mercury MR-1 Launch Vehicle: Redstone. Engine cut off after 1 sec, vehicle fell back to the pad from a few centimeters height,but did not explode. This faulty ground-support circuitry had not been noted on some 60 previous Redstone firings.. Redstone MRLV-1 Suborbital launch attempt. After a four- or five-inch liftoff, MR-1 launched its escape tower but not the capsule. The undamaged spacecraft was recovered for reuse.

• 1960 December 19 16:15 - Mercury MR-1A Launch Vehicle: Redstone. Redstone MRLV-3 Apogee: 210 km (130 mi). Range: 379 km (235 mi). Mercury-Redstone 1A (MR-1A) was launched from Cape Canaveral in a repeat of the November 21, 1960, mission and was completely successful. This was the third attempt to accomplish the objectives established for this flight. The first attempt on November 7, 1960, was canceled as a result of a helium leak in the spacecraft reaction control system relief valve, and on November 21, 1960, the mission could not be completed because of premature cut-off of the launch vehicle engines. Objectives of the MR-1A flight were to qualify the spacecraft for space flight and to qualify the flight system for a primate flight scheduled shortly thereafter. Close attention was given to the spacecraft-launch vehicle combination as it went through the various flight sequences: powered flight; acceleration and deceleration; performance of the posigrade rockets; performance of the recovery system; performance of the launch, tracking, and recovery phases of the operation; other events of the flight including retrorocket operation in a space environment; and operation of instrumentation. Except that the launch vehicle cut-off velocity was slightly higher than normal, all flight sequences were satisfactory; tower separation, spacecraft separation, spacecraft turnaround, retrofire, retropackage jettison, and landing system operation occurred or were controlled as planned. The spacecraft reached a maximum altitude of 130.68 statute miles, a range of 234.8 statute miles, and a speed of 4,909.1 miles per hour. Fifteen minutes after landing in the Atlantic Ocean, the recovery helicopter picked up the spacecraft to complete the successful flight mission.

• 1961 January 31 16:54 - Mercury MR-2 Launch Vehicle: Redstone. Redstone MRLV-2 Apogee: 251 km (155 mi). Ham, a 37-pound chimpanzee, was aboard the spacecraft. The over-acceleration of the launch vehicle coupled with the velocity of the escape rocket caused the spacecraft to attain a higher altitude and a longer range than planned. In addition, the early depletion of the liquid oxygen caused a signal that separated the spacecraft from the launch vehicle a few seconds early. However spacecraft recovery was effected, although there were some leaks and the spacecraft was taking on water. Ham appeared to be in good physiological condition, but sometime later when he was shown the spacecraft it was visually apparent that he had no further interest in cooperating with the space flight program. Despite the over-acceleration factor, the flight was considered to be successful.

• 1961 March 24 17:30 - Mercury MR-BD Launch Vehicle: Redstone. Redstone MRLV-5 Apogee: 181 km (112 mi). Suborbital test of Redstone modifications using a boilerplate Mercury capsule. The test was done at von Braun's insistence against Shepard's wishes, thereby putting the first US manned flight after Gagarin's.

• 1961 May 5 14:34 - Mercury MR-3 Launch Vehicle: Redstone. Redstone MRLV-7 Apogee: 187 km (116 mi). Alan Shepard first American in space, less than a month after Gagarin and only on a 15 minute suborbital flight. Only manned flight with original Mercury capsule design (tiny round porthole and periscope a la Vostok). If NASA had not listened to Von Braun, Shepard would have flown on the MR-BD flight of 24 March, beating Gagarin by three weeks and becoming the first man in space (though not in orbit). Shepard's capsule reached an altitude of 115.696 miles, range of 302 miles,and speed of 5,100 miles per hour. He demonstrated control of a vehicle during weightlessness and high G stresses. Recovery operations were perfect; there was no damage to the spacecraft; and Astronaut Shepard was in excellent condition.

• 1961 July 21 12:20 - Mercury MR-4 Launch Vehicle: Redstone. Redstone MRLV-8 Apogee: 190 km (110 mi). The Mercury capsule, Liberty Bell 7, manned by Astronaut Virgil I. Grissom, boosted by a Redstone rocket, reached a peak altitude of 190.3 km and a speed of 8,335 km per hour. After a flight of 15 minutes and 37 seconds, the landing was made 487 km downrange from the launch site. The hatch blew while still in water, and the capsule sank; Grissom saved, though his suit was filling up with water through open oxygen inlet lines.

  This was the second and final manned suborbital Mercury Redstone flight, and the first flight with trapezoidal window. Further suborbital flights (each astronaut was to make one as a training exercise) were cancelled. An attempt to recover the capsule in very deep water in 1994 not successful. It was finally raised in the summer of 1999.
