16 November 1973: Skylab 4 lifted off from Launch Complex 39B, Kennedy Space Center, at 14:01:23 UTC. Aboard the Apollo Command and Service Module were NASA astronauts Lieutenant Colonel Gerald Paul Carr, U.S. Marine Corps, Mission Commander;  Lieutenant Colonel William Reid Pogue, U.S. Air Force; and Edward George Gibson, Ph.D. This would be the only space mission for each of them. They would spend 84 days working aboard Skylab.

The S-IB was built by Chrysler Corporation Space Division at the Michoud Assembly Facility near New Orleans, Louisiana. It was powered by eight Rocketdyne H-1 engines, burning RP-1 and liquid oxygen. Eight Redstone rocket fuel tanks, with 4 containing the RP-1 fuel, and 4 filled with liquid oxygen, surrounded a Jupiter rocket fuel tank containing liquid oxygen. Total thrust of the S-IB stage was 1,666,460 pounds (7,417.783 kilonewtons) and it carried sufficient propellant for a maximum 4 minutes, 22.57 seconds of burn. First stage separation was planned for n altitude of 193,605 feet, with the vehicle accelerating through 7,591.20 feet per second (2,313.80 meters per second).

The McDonnell Douglas Astronautics Co. S-IVB stage was built at Huntington Beach, California. It was powered by one Rocketdyne J-2 engine, fueled by liquid hydrogen and liquid oxygen. The J-2 produced 229,714 pounds of thrust (1,021.819 kilonewtons), at high thrust, and 198,047 pounds (880.957 kilonewtons) at low thrust). The second stage carried enough fuel for 7 minutes, 49.50 seconds burn at high thrust. Orbital insertion would be occur 9 minutes, 51.9 seconds after launch, at an altitude of 98.5 miles (158.5 kilometers) with a velocity of 25,705.77 feet per second (7,835.12 meters per second).

The Skylab-configuration Saturn IB rocket was 223 feet, 5.9 inches (68.119 meters) tall. It had a maximum diameter of 22.8 feet (6.949 meters), and the span across the first stage guide fins was 40.7 feet (12.405 meters). Its empty weight was 159,000 pounds (72,122 kilograms) and at liftoff, it weighed 1,296,000 pounds (587,856 kilograms). It was capable of launching a 46,000 pound (20,865 kilogram) payload to Earth orbit.

14 November 1969: At 16:22:00.68 UTC (11:22:00 a.m., Eastern Standard Time), the Apollo 12 Saturn V (AS-507) lifted off from Launch Complex 39A, Kennedy Space Center, Cape Canaveral, Florida.

This was the second manned space flight to the Moon. The flight crew were Commander Charles “Pete” Conrad, Jr., United States Navy, Mission Commander; Commander Richard F. Gordon, Jr., U.S. Navy, Command Module Pilot; Commander Alan L. Bean, U.S. Navy, Lunar Module Pilot.

Their destination was Oceanus Procellarum.

Two lightning strikes 36.5 seconds after liftoff caused the spacecraft’s automatic systems to shut down three fuel cells, leaving Apollo 12 operating on battery power. A third electrical disturbance at T + 52 seconds caused the “8 ball” attitude indicator in the cockpit to fail. A quick thinking ground controller, the “EECOM,” called “Try SCE to Aux.” Alan Bean recalled this from a simulation a year earlier, found the correct switch and restored the failed systems.

The lightning discharge was caused by the Apollo 12/Saturn V vehicle accelerating through rain at approximately 6,300 feet (1,950 meters). There were no thunderstorms in the area. Post-flight analysis indicates that it is probable that the lightning discharge started at the top of the Apollo 12/Saturn V vehicle. Energy of the discharge was estimated at 10⁴–10⁸ joules.

Soon after passing Mach 1, the Saturn V rocket encountered the maximum dynamic pressure (“Max Q”) of 682.95 pounds per square foot (0.327 Bar) as it accelerated through the atmosphere.

The Saturn V rocket was a three-stage, liquid-fueled heavy launch vehicle. Fully assembled with the Apollo Command and Service Module, it stood 363 feet, 0.15 inches (110.64621 meters) tall, from the tip of the escape tower to the bottom of the F-1 engines. The first and second stages were 33 feet, .2 inches (10.089 meters) in diameter. Fully loaded and fueled the rocket weighed approximately 6,200,000 pounds (2,948,350 kilograms).¹ It could lift a payload of 260,000 pounds (117,934 kilograms) to Low Earth Orbit.

The first stage was designated S-IC. It was designed to lift the entire rocket to an altitude of 220,000 feet (67,056 meters) and accelerate to a speed of more than 5,100 miles per hour (8,280 kilometers per hour). The S-IC stage was built by Boeing at the Michoud Assembly Facility, New Orleans, Louisiana. It was 138 feet (42.062 meters) tall and had an empty weight of 290,000 pounds (131,542 kilograms). Fully fueled with 203,400 gallons (770,000 liters) of RP-1 and 318,065 gallons (1,204,000 liters) of liquid oxygen, the stage weighed 5,100,000 pounds (2,131,322 kilograms). It was propelled by five Rocketdyne F-1 engines, producing 1,522,000 pounds of thrust (6770.19 kilonewtons), each, for a total of 7,610,000 pounds of thrust at Sea Level (33,851 kilonewtons).² These engines were ignited 6.50 seconds prior to Range Zero and the outer four burned for 161.74 seconds. The center engine was shut down after 135.24 seconds to reduce the rate of acceleration. The F-1 engines were built by the Rocketdyne Division of North American Aviation at Canoga Park, California.

The S-II second stage was built by North American Aviation at Seal Beach, California. It was 81 feet, 7 inches (24.87 meters) tall and had the same diameter as the first stage. The second stage weighed 80,000 pounds (36,000 kilograms) empty and 1,060,000 pounds loaded. The propellant for the S-II was liquid hydrogen and liquid oxygen. The stage was powered by five Rocketdyne J-2 engines, also built at Canoga Park. Each engine produced 232,250 pounds of thrust (1,022.01 kilonewtons), and combined, 1,161,250 pounds of thrust (5,165.5 kilonewtons).³

The Saturn V third stage was designated S-IVB. It was built by Douglas Aircraft Company at Huntington Beach, California. The S-IVB was 58 feet, 7 inches (17.86 meters) tall with a diameter of 21 feet, 8 inches (6.604 meters). It had a dry weight of 23,000 pounds (10,000 kilograms) and fully fueled weighed 262,000 pounds. The third stage had one J-2 engine and also used liquid hydrogen and liquid oxygen for propellant. The S-IVB would place the Command and Service Module into Low Earth Orbit, then, when all was ready, the J-2 would be restarted for the Trans Lunar Injection.

Eighteen Saturn V rockets were built. Only three still exist. One, on display at the Johnson Space Center, Houston, Texas, is made up of the the S-IC first stage of SA-514, S-II second stage of SA-515, and S-IVB third stage of SA-513. It is the only one consisting of flight-certified hardware. The Apollo Command and Service Module is CSM-115, originally intended for the Apollo 19 mission.

¹ The AS-507 total vehicle mass at First Stage Ignition (T – 6.50 seconds) was 6,137,868  pounds (2,784,090 kilograms).

² Post-flight analysis gave the total thrust of AS-507’s S-IC stage as 7,594,000 pounds of thrust (33,780 kilonewtons).

³ Post-flight analysis gave the total thrust of AS-507’s S-II stage as 1,161,534 pounds of thrust (5,166.8 kilonewtons).

⁴ Post-flight analysis gave the total thrust of AS-507’s S-IVB stage as 206,956 pounds of thrust (920.6 kilonewtons) during the first burn; 207,688 pounds (923.8 kilonewtons) during the second burn.

12 November 1995, 12:30:43.071 UTC, T minus Zero: Space Shuttle Atlantis (STS-74) is launched from Launch Complex 39A, Kennedy Space Center, Cape Canaveral, Florida.

The mission commander was Colonel Kenneth Donald Cameron, United States Marine Corps, and Colonel James Donald Halsell, Jr., United States Air Force, was the shuttle pilot.

There were three mission specialists on this flight: Colonel Chris Austin Hadfield, Royal Canadian Air Force; Colonel Jerry Lynn Ross, U.S. Air Force; and Colonel William Suries McArthur, Jr., United States Army. Colonels Cameron, Halsell, Hadfield and McArthur had all been military test pilots before joining the space program. Colonel Ross was a flight test engineer.

STS-2 was planned as a five-day mission. In addition to continued testing of the orbital vehicle, on this flight the Remote Manipulator System (the “robot arm”) would be operated for the first time in space. A number of other experiments were carried in the cargo bay. However, when one of the three fuel cells producing electrical power and water failed, the mission was cut short.

Columbia landed on Rogers Dry Lake at Edwards Air Force Base, California, at 1:23 p.m. PST, 14 November 1981. The shuttle completed 37 orbits. The total duration of the flight was 2 days, 6 hours, 13 minutes, 13 seconds.

11 November 1966: Gemini 12 lifted off from Launch Complex 19 at the Cape Canaveral Air Force Station, Florida, at 3:36.33.419 p.m., Eastern Standard Time. Two NASA Astronauts, Captain James A Lovell, Jr., United States Navy, and Major Edwin E. (“Buzz”) Aldrin, Jr., United States Air Force, were the crew. This was the second space flight for Lovell, who had previously flown on Gemini VII, and would later serve as Command Module Pilot on Apollo 8 and Mission Commander on Apollo 13. It was Aldrin’s first space flight. He would later be the Lunar Module Pilot of Apollo 11, and was the second human to set foot of the surface of the Moon.

The Gemini 12 mission was to rendezvous and docking with an Agena Target Vehicle, which had been launched from Launch Complex 14, 1 hour, 38 minutes, 34.731 seconds earlier by an Atlas Standard Launch Vehicle (SLV-3), and placed in a nearly circular orbit with a perigee of 163 nautical miles (187.6 statute miles/301.9 kilometers) and apogee of 156 nautical miles (179.5 statute miles/288.9 kilometers).

The two-man Gemini spacecraft was built by the McDonnell Aircraft Corporation of St. Louis, the same company that built the earlier Mercury space capsule. The spacecraft consisted of a reentry module and an adapter section. It had an overall length of 19 feet (5.791 meters) and a diameter of 10 feet (3.048 meters) at the base of the adapter section. The reentry module was 11 feet (3.353 meters) long with a diameter of 7.5 feet (2.347 meters). The weight of the Gemini varied from ship to ship, but Spacecraft 12 weighed 8,296.47 pounds (3,763.22 kilograms) at liftoff.

The Titan II GLV was a “man-rated” variant of the Martin SM-68B intercontinental ballistic missile. It was assembled at Martin Marietta’s Middle River, Maryland plant so as not to interfere with the production of the ICBM at Denver, Colorado. Twelve GLVs were ordered by the Air Force for the Gemini Program.

The Titan II GLV was a two-stage, liquid-fueled rocket. The first stage was 63 feet (19.202 meters) long with a diameter of 10 feet (3.048 meters). The second stage was 27 feet (8.230 meters) long, with the same diameter. The 1st stage was powered by an Aerojet Engineering Corporation LR-87-7 engine which combined two combustion chambers and exhaust nozzles with a single turbopump unit. The engine was fueled by a hypergolic combination of hydrazine and nitrogen tetroxide. Ignition occurred spontaneously as the two components were combined in the combustion chambers. The LR-87-7 produced 430,000 pounds of thrust (1,912.74 kilonewtons).¹ It was not throttled and could not be shut down and restarted. The 2nd stage used an Aerojet LR-91 engine which produced 100,000 pounds of thrust (444.82 kilonewtons).²

The Gemini/Titan II GLV combination had a total height of 109 feet (33.223 meters) and weighed approximately 340,000 pounds (154,220 kilograms) when fueled.³

Gemini XII was the tenth and last flight of the Gemini program. The purpose of this mission was to test rendezvous and docking with an orbiting Agena Target Docking Vehicle and to test extravehicular activity (“EVA,” or “space walk”) procedures. Both of these were crucial parts of the upcoming Apollo program and previous problems would have to be resolved before the manned space flight projects could move to the next phase.

Buzz Aldrin had made a special study of EVA factors, and his three “space walks,” totaling 5 hours, 30 minutes, were highly successful. The rendezvous and docking was flown manually because of a computer problem, but was successful. In addition to these primary objectives, a number of scientific experiments were performed by the two astronauts.

Gemini XII reentered Earth’s atmosphere and splashed down in the Atlantic Ocean, just 3.8 nautical miles (4.4 statute miles/7.0 kilometers) from the planned target point. Lovell and Aldrin were hoisted aboard a Sikorsky SH-3A Sea King helicopter and transported to the primary recovery ship, USS Wasp (CVS-18). The total duration of the flight was 3 days, 22 hours, 34 minutes, 31 seconds.

¹ Post-flight analysis gave the total average thrust of GLV-12’s first stage as 458,905 pounds of thrust (2,041.31 kilonewtons)

² Post-flight analysis gave the total average thrust of GLV-12’s second stage as 99,296 pounds of thrust (441.69 kilonewtons)

³ Gemini XII/Titan II GLV (GLV-12) weighed 345,710 pounds (156,811 kilograms) at Stage I ignition.
