5 February 1971, 09:18:11 UTC, T + 108:15:09.30: The Apollo 14 Lunar Module Antares (LM-8), with astronauts Alan B. Shepard and Edgar D. Mitchell aboard, landed at the Fra Mauro Highlands, The Moon.
This was the third manned lunar landing. It was 9 years, 8 months, 30 days, 18 hours, 43 minutes, 58 seconds since Shepard had lifted off from Cape Canaveral aboard Freedom 7, becoming the first American astronaut launched into space.
5 hours, 36 minutes later, at 14:54 UTC, T + 113:51, Alan Shepard stepped on to the surface of The Moon.
31 January 1971, 04:03:02 a.m., Eastern Standard Time: Apollo 14 (AS-509) lifted off for The Moon from Space Flight Launch Complex 39A, Kennedy Space Center, Cape Canaveral, Florida. The Mission Commander was Captain Alan Bartlett Shepard, Jr., United States Navy. The Command Module Pilot was Colonel Stuart Allen Roosa, United States Air Force, and the Lunar Module Pilot was Captain Edgar Dean Mitchell, Sc.D., United States Navy. Their destination was the Fra Mauro Highlands.
Apollo 14 was the eighth manned mission of the Apollo Program, and the third to land on the surface of the moon.
Alan Shepard was the first American astronaut. He flew into space aboard a Mercury spacecraft, Freedom 7, launched from Cape Canaveral by a Redstone rocket, 5 May 1961.
Mitchell and Roosa had not flown in space before. This would be their only space flight.
The Apollo Command/Service Module was built by the Space and Information Systems Division of North American Aviation, Inc., at Downey, California.
The SPS engine was an AJ10-137, built by Aerojet General Corporation of Azusa, California. It burned a hypergolic fuel combination of Aerozine 50 and nitrogen tetraoxide, producing 20,500 pounds of thrust (91.19 kilonewtons). It was designed for a 750 second burn, or 50 restarts during a flight.
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 (110.642 meters) tall. The first and second stages were 33 feet (10.058 meters) in diameter. Fully loaded and fueled the rocket weighed 6,200,000 pounds (2,948,350 kilograms). 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 (33,850.97 kilonewtons). These engines were ignited seven seconds prior to lift off and the outer four burned for 168 seconds. The center engine was shut down after 142 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 (717.28 kilonewtons).
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. They were the most powerful machines ever built by man.
27 December 1968 15:51:42 UTC, T plus 147:00:42.0: Apollo 8 splashes down in the Pacific Ocean south of the Hawaiian Islands, within 5,000 yards (4,572 meters) of the recovery ship USS Yorktown (CVS-10). The spacecraft arrived before sunrise, landing in 10-foot (3-meter) swells. The parachutes dragged the capsule and left it floating upside down. The inflatable pontoons righted it after about six minutes.
The three astronauts, Frank F. Borman II, James A. Lovell, Jr., and William A. Anders, were hoisted aboard a Sikorsky SH-3D Sea King helicopter, Bu. No. 152711, and flown to the aircraft carrier.
Apollo 8 was the first manned space mission to leave Earth orbit and to travel to another planetary body. It proved all of the space flight techniques that would be required for the upcoming Apollo 11 landing on the Moon.
Sikorsky SH-3D Sea King 66, Bureau of Aeronautics serial number 152711, assigned to HS-4 (“Black Knights”) was the primary recovery helicopter for Apollo 8, Apollo 10, Apollo 11, Apollo 12 and Apollo 13. It was lost at sea off NALF Imperial Beach, California, 4 June 1975. One crewman was killed.
19 December 1972: At 2:25 p.m. EST—12 days, 13 hours, 51 minutes, 59 seconds after departing the Kennedy Space Center at Cape Canaveral, Florida—the Apollo 17 command module America (CM-112) returned to Earth, splashing down in the South Pacific Ocean, approximately 350 miles (563 kilometers) southeast of Samoa. The three 83 foot, 6 inch diameter (25.451 meters) ring sail main parachutes had deployed at an altitude of 10,500 feet (3,200 meters) and slowed the capsule to 22 miles per hour (35.4 kilometers per hour) before it hit the ocean’s surface.
The landing had a high degree of accuracy, coming within 4.0 miles (6.44 kilometers) of the recovery ship, the aircraft carrier USS Ticonderoga (CVS-14).
The flight crew was picked up by a Sikorsky SH-3G Sea King helicopter, Bu. No. 149930, of HC-1, and transported to Ticonderoga. The three astronauts, Eugene A. Cernan, Ronald A. Evans and Harrison H. Schmitt, stepped aboard the aircraft carrier 52 minutes after splashdown.
The splashdown of Apollo 17 brought to an end the era of manned exploration of the Moon which had begun just 3 years, 3 days, 5 hours, 52 minutes, 59 seconds earlier with the launch of Apollo 11.
Only 12 men have set foot on The Moon. In 46 years, no human has returned.
14 December 1972: At 4:54:36 p.m., CST (Houston time), the Ascent Stage of the Apollo 17 Lunar Module Challenger lifted off from the landing site in the Taurus-Littrow Valley, The Moon. On board were Mission Commander Eugene A. Cernan and the LM Pilot, Harrison H. Schmitt.
The two Astronauts had been on the surface of the Moon for 3 days, 2 hours, 59 minutes, 40 seconds. During that time they made three excursions outside the lunar lander, totaling 22 hours, 3 minutes 57 seconds.
Apollo 17 was the last manned mission to the Moon in the Twentieth Century. Gene Cernan was the last man to stand on the surface of the Moon.
