7 December 1972: At 05:33:00.63 UTC (12:33 a.m., Eastern Standard Time), Apollo 17, the last manned mission to The Moon in the 20th century, lifted off from Launch Complex 39A at the Kennedy Space Center, Cape Canaveral, Florida. The destination was the Taurus-Littrow Valley.

The Mission Commander, on his third space flight, was Eugene A. Cernan. The Command Module Pilot was Ronald A. Evans, on his first space flight, and the Lunar Module Pilot was Harrison H. Schmitt, also on his first space flight.

Schmitt was placed in the crew because he was a professional geologist. He replaced Joe Engle, an experienced test pilot who had made sixteen flights in the X-15 hypersonic research rocketplane. Three of those flights were higher than the 50-mile altitude, qualifying Engle for U.S. Air Force astronaut wings.

The launch of Apollo 17 was delayed for 2 hours, 40 minutes, due to a minor mechanical malfunction. When it did liftoff, the launch was witnessed by more than 500,000 people.

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.

Apollo 17 launched 3 years, 4 months, 20 days, 16 hours, 1 minute, 0 seconds after Apollo 11, the first manned flight to The Moon.

5 December 2014: At 7:05 a.m., EST, a United Launch Alliance Delta IV Heavy carried the first Lockheed Martin Corporation Orion spacecraft, EFT-1, into Earth orbit.

This was the first test flight of the new deep space vehicle. There were no astronauts aboard.

Liftoff weight of the Orion/Delta IV Heavy was 1,630,000 pounds (739,356 kilograms).

The Orion Multi-Purpose Crew Vehicle is produced by Lockheed Martin Corporation, and consists of a Launch Abort System, Crew Module, Service Module and a Stage Adapter. Gross weight at liftoff is 78,010 pounds (35,385 kilograms). The Crew Module accommodates 4 astronauts. Its gross liftoff weight is 22,900 pounds (10,387 kilograms), and landing weight is 20,500 pounds (9,299 kilograms). The crew area has a volume of 316 cubic feet (8.95 cubic meters).

A series of eight parachutes decelerates the Orion Crew Module on re-entry. Touch-down speed is planned for less than 20 miles per hour (32 kilometers per hour).

On its second orbit, the space craft reached an altitude of approximately 3,600 miles (5,794 kilometers). This allowed the vehicle’s re-entry speed to exceed 20,000 miles per hour (32,187 kilometers per hour), generating heat shield temperatures of over 4,000 °F. (2,204 °C.)

The Orion completed two orbits and landed in the eastern Pacific Ocean, approximately 650 miles (1,046 kilometers) southwest of San Diego, California.

The Delta IV Heavy combines a Delta IV two-stage liquid-fueled rocket with two Common Core Boosters. It is capable of placing a 63,471 pound (28,790 kilograms) payload into Low Earth Orbit.

The Delta IV Common Booster Core is 134.0 feet (40.8 meters) long and 16 feet, 10.0 inches (5.131 meters) in diameter. They are each powered by an Aerojet Rocketdyne RS-68A engine, producing 705,250 pounds of thrust (3,137.11 kilonewtons), at Sea Level, each, giving the Delta IV Heavy a total of 2,115,750 pounds of thrust (9,411.32 at liftoff. The RS-68A is 17.1 feet (5.21 meters) long, 8.0 feet (2.44 meters) in diameter, and weighs 14,870 pounds (6,745 kilograms).

The Delta IV Heavy’s second stage is 42.8 feet (13.05 meters) long, and is also 16 feet, 10.0 inches in diameter. It uses an Aerojet Rocketdyne RL-10B-2 engine, producing 24,750 pounds of thrust (110.09 kilonewtons) of thrust. The RL-10B-2 is 13.6 feet (4.15 meters) long, 7.0 feet (2.13 meters) in diameter, and weighs 611 pounds (277 kilograms).

All engines are fueled with liquid oxygen and liquid hydrogen.

47–49 seconds after liftoff, depending on launch profile, the first stage (center CBC) engine throttles down to 54.5%, while the boosters remain at full throttle. After 235 seconds of flight, the booster engines throttle down to 54.5%, and 7 seconds later, cut off. The boosters are jettisoned at 245 seconds. 1 second later, the first stage RS-68 throttles up to 108.5%. It cuts of at 328 seconds, and the first and second stage separate at 334 seconds. The second stage engine ignites at 347 seconds, and cuts off at 411–421 seconds.

RUSHWORTH, Robert H., Major General, USAF 5 December 1963: On Flight 97 of the X-15 Program, Major Robert A. Rushworth flew the number one aircraft, Air Force serial number 56-6670, to an altitude of 101,000 feet 30,785 meters) and reached Mach 6.06 (4,018 miles per hour/6,466 kilometers per hour).

The rocketplane was dropped from the Boeing NB-52B Stratofortress “mother ship” 52-008, Balls 8, flying at 450 knots (833.4 kilometers per hour) at 45,000 feet (13,716 meters) over Delamar Dry Lake, Nevada. Rushworth ignited the Reaction Motors XLR-99-RM-1 rocket engine, which burned for 81.2 seconds before shutting down.

The flight plan had called for an altitude of 104,000 feet (31,699 meters), a 78 second burn and a maximum speed of Mach 5.70. With the difficulties of flying such a powerful rocketplane, Rushworth’s flight was actually fairly close to plan. During the flight the right inner windshield cracked.

Bob Rushworth landed the X-15 on Rogers Dry Lake at Edwards Air Force Base, California, after a flight of 9 minutes, 34.0 seconds.

Mach 6.06 was the highest Mach number reached for an unmodified X-15.

56-6670 flew 81 of the 199 flights of the X-15 Program. It is in the collection of the Smithsonian Institution National Air and Space Museum.

From 1960 to 1966, Bob Rushworth made 34 flights in the three X-15s, more than any other pilot.

4 December 1998, 08:35:34 UTC: Space Shuttle Endeavour (STS-88) lifts off from Launch Complex 39A, Kennedy Space Center, Cape Canaveral, Florida, on an 11-day mission to assemble the Unity docking connector module (Node 1) of the International Space Station.

The Mission Commander of STS 88 was Colonel Robert Donald Cabana, United States Marine Corps, on his fourth (and final) space flight. The Pilot was Colonel Frederick Wilford Sturcklow, U.S. Marine Corps, on his first space flight. There were four Mission Specialists: Colonel Jerry Lynn Ross, U.S. Air Force; Major Nancy Jane Currie, U.S. Army, on her third space flight; James Hansen Newman, Ph.D., on his third flight; and Sergei Konstantinovick Krikalev (Серге́й Константинович Крикалёв), a Cosmonaut-Researcher for NPO Energia, on his fourth of six space flights.

The first segment of the space station was the Functional Cargo Block, known as Zarya (Заря́), which had been placed in Earth orbit two weeks earlier, 20 November 1998, by a Proton-K three-stage rocket, launched from the Baikonur Cosmodrome.

Node 1 provided a docking station for arriving space craft. Adaptor points for additional modules were built into the node’s circumference. Endeavour carried Node 1 in its cargo bay. It was maneuvered into position and installed using the shuttle’s robotic arm, operated by Major Currie.

4 December 1965, 19:30:03.702 UTC: At 2:30 p.m., Eastern Standard Time, Gemini VII/Titan II GLV-7 lifted of from Launch Complex 19 at the Cape Kennedy Air Force Station, Cape Kennedy, Florida. On board were Major Frank F. Borman II, United States Air Force, the mission command pilot, and Lieutenant Commander James A. Lovell, Jr., United States Navy, pilot. During the climb to Earth orbit, the maximum acceleration reached was 7.3 Gs.

Gemini VII was placed into Earth orbit at an initial maximum altitude (apogee) of 177.1 nautical miles (327.8 kilometers) and a minimum (perigee) of 87.2 nautical miles (161.5 kilometers), at a velocity of 16,654.1 miles per hour (26,802.2 kilometers per hour), relative to Earth.

This mission was a planned 14-day flight which would involve an orbital rendezvous with another manned spacecraft, Gemini VI-A. The actual total duration of the flight was 330 hours, 35 minutes, 1 second.

The two-man Gemini spacecraft was built by the McDonnell Aircraft Corporation of St. Louis, Missouri, the same company that built the earlier Mercury space capsule. The spacecraft consisted of a series of cone-shaped segments forming a reentry module and an adapter section. It had an overall length of 18 feet, 9.84 inches (5.736 meters) and a maximum diameter of 10 feet, 0.00 inches (3.048 meters) at the base of the equipment section. The reentry module was 11 feet (3.353 meters) long with a maximum diameter of 7 feet, 6.00 inches (2.347 meters). The Gemini re-entry heat shield was a spherical section with a radius of 12 feet, 0.00 inches (3.658 meters). The weight of the Gemini spacecraft varied from ship to ship. Gemini VII had a gross weight of 8,076.10 pounds (3,663.26 kilograms) at launch. It was shipped from St. Louis to Cape Kennedy in early October 1965.

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 GLV-7 first and second stages were shipped from Middle River to Cape Kennedy on 9 October 1965.

The Titan II GLV was a two-stage, liquid-fueled rocket. The first stage was 70 feet, 2.31 inches (21.395 meters) long with a diameter of 10 feet (3.048 meters). It was powered by an Aerojet Engineering Corporation LR87-7 engine which combined two combustion chambers and exhaust nozzles with a single turbopump unit. The engine was fueled by Aerozine 50, a hypergolic 51/47/2 blend of hydrazine, unsymetrical-dimethyl hydrazine, and water. Ignition occurred spontaneously as the components were combined in the combustion chambers. The LR87-7 produced approximately 430,000 pounds of thrust (1,912.74 kilonewtons). It was not throttled and could not be shut down and restarted. Post flight analysis indicated that the first stage engine of GLV-7 had produced an average of 462,433 pounds of thrust (2,057.0 kilonewtons). The second stage was 25 feet, 6.375 inches (7.031 meters) long, with the same diameter, and used an Aerojet LR91 engine which produced approximately 100,000 pounds of thrust (444.82 kilonewtons), also burning Aerozine 50. GLV-7’s LR91 produced an average of 102,584 pounds of thrust (456.3 kilonewtons).

The Gemini/Titan II GLV-7 combination had a total height of 107 feet, 7.33 inches (32.795 meters) and weighed 346,228 pounds (157,046 kilograms) at ignition.
