Mercury Atlas 9 (MA-9), consisting of Faith 7 and Atlas 130-D, lifts off from Launch Complex 14 at the Cape Canaveral Air Force Station, Florida, at 13:04:13 UTC, 15 May 1963. (NASA)
15 May 1963: At 8:04:13.106 a.m., Eastern Standard Time, Mercury-Atlas 9, carrying NASA astronaut, L. Gordon Cooper aboard Faith 7, lifted off from Launch Complex 14, Cape Canaveral Air Force Base, Florida. Cooper reported, “The liftoff was smooth, but very definite, the acceleration was very pleasant. The booster had a very good feel to it and it felt like we were real on the go, there.” The maximum acceleration experienced during launch was 7.6 gs.
Faith 7 separated from the Atlas booster at T+00:05:05.5.3 and entered low Earth orbit with an apogee of 165.9 statute miles (267.0 kilometers) and perigee of 100.3 statute miles (161.4 kilometers). The orbital period was 88 minutes, 45 seconds. The spacecraft’s velocity was 25,714.0 feet per second (7,837.6 meters per second), or 17,532.3 miles per hour (28,215.5 kilometers per hour).

MA-9 was the final flight of Project Mercury. Gordon Cooper flew 22.5 orbits. Due to electrical system problems that began on the 21st orbit, he had to fly a manual reentry which resulted in the most accurate landing of the Mercury program.
The spacecraft’s three retrorockets fired 5 second intervals beginning at T+33:59:30. 34 hours, 19 minutes, 49 seconds after lift off, Faith 7 “splashed down” approximately 70 miles (112.7 kilometers) southeast of Midway Atoll in the North Pacific Ocean, just 4.4 miles (7.1 kilometers) from the primary recovery ship, the United States Navy Ticonderoga-class aircraft carrier USS Kearsarge (CV-33).

The Mercury spacecraft, which Cooper named Faith 7, was built by McDonnell Aircraft Corporation, St. Louis, Missouri, which would also build the follow-on, two-place Gemini spacecraft. It was the 20th and final Mercury capsule to be built, and was one of four which were modified to support a day-long mission. Some items considered unnecessary were deleted and extra oxygen and battery capacity was added.
Designed to carry one pilot, the Mercury space craft could be controlled in pitch, roll and yaw by thrusters. The space capsule was truncated cone with sides angled 20° from the longitudinal axis. It was 6 feet, 10 inches (2.083 meters) long and had a maximum diameter of 6 feet, 2.50 inches (1.892 meters). The total height of the spacecraft, from the tip of the aero spike to the booster adapter, was 26 feet, 1.26 inches (7.957 meters). Faith 7 weighed 4,330.82 pounds (1,964.43 kilograms) at liftoff.
During flight outside the atmosphere, the Mercury spacecraft could be controlled in its pitch, roll and yaw axes by hydrogen peroxide-fueled reaction control thrusters. Both manual and automatic attitude control were available. It could not accelerate or decelerate (except for reentry) so it could not change its orbit.
The spacecraft cabin was pressurized to 5.5 psi with 100% oxygen. Gordon Cooper wore a modified B.F. Goodrich Mark IV full-pressure suit and flight helmet for protection in the event that cabin pressure was lost. Cooper’s suit varied considerably from those worn by previous Mercury astronauts.

The rocket, a “1-½ stage” liquid-fueled Atlas LV-3B, number 130-D, was built by the Convair Division of General Dynamics at San Diego, California. It was developed from a U.S. Air Force SM-65 Atlas D intercontinental ballistic missile, modified for use as a “man-rated” orbital launch vehicle.
The LV-3B was 65 feet (19.812 meters) long from the base to the Mercury adapter section, and the tank section is 10 feet (3.038 meters) in diameter. The complete Mercury-Atlas orbital launch vehicle is 93 feet (28.436 meters) tall, including the escape tower. When ready for launch it weighed approximately 260,000 pounds (117,934 kilograms).

The Atlas’ three engines were built by the Rocketdyne Division of North American Aviation, Inc., at Canoga Park, California. Two Rocketdyne LR89-NA-5 engines and one LR105-NA-5 produced 341,140 pounds (1,517.466 kilonewtons) of thrust. The rocket was fueled by a highly-refined kerosene, RP-1, with liquid oxygen as the oxidizer.

SA 513/Skylab 1 (SL-1) launch from LC 39A, 17:30:00 UTC, 14 May 1973. (NASA)
14 May 1973: At 12:30:00 p.m. Eastern Standard Time, America’s first orbital space station, Skylab, was launched by a Saturn V Launch Vehicle, SA-513, from Launch Complex 39A at the Kennedy Space Center, Cape Canaveral, Florida. First motion was detected at T + 000:00:00.22.
After first stage separation, the S-IC/S-II interstage connector failed to separate from the second stage. because of this, orbital insertion occurred at T + 000:09:59.0; 0.64 seconds later than planned, and 0.6 meters per second faster than predicted. The S-II stage followed the Skylab into Earth orbit. Skylab’s orbit was almost perfectly circular, with an apogee of 234.2 nautical miles (433.7 kilometers), and perigee of 233.0 nautical miles (431.5 kilometers). The orbital period was 93.23 minutes, with a velocity of 17,111 miles per hour (27,537 kilometers per hour).
Skylab was unmanned at launch. Three 3-man crews were carried to the station aboard Apollo command/service modules launched by the smaller Saturn IB rocket.
Skylab’s mission was to demonstrate that humans could live and work in orbit for extended periods of time, and that they could also perform useful work and research. The first crew had to make repairs in orbit to extend a damaged solar array and to use a spare solar panel as a shade to prevent sunlight from overheating the station. This was the first orbital repair mission. Astronauts occupied Skylab for 171 days, 13 hours and conducted over 300 scientific projects.

The Skylab was built from an empty Saturn V third stage, S-IVB number 213, modified by McDonnell Douglas. The launch vehicle consisted of the first two stages of a Saturn V rocket, an S-IC first stage and an S-II second stage.
The total vehicle weight at engine ignition was 6,297,336 pounds (2,856,424 kilograms). Post-launch analysis determined that the five Rocketdyne F-1 engines of SA-513’s S-IC first stage generated 7,551,000 pounds of thrust (33,588.52 kilonewtons) at Sea Level.
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 (8,200 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 33 feet (10.058 meters) in diameter. Its empty weight was 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).
The S-IC was propelled by five Rocketdyne F-1 engines, producing 1,522,000 pounds of thrust, each, for a total of 7,610,000 pounds of thrust at Sea Level. 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, Inc., 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, and combined, 1,161,250 pounds of thrust.
The unmanned space station’s orbit decayed and it reentered on 11 July 1979. It broke up and parts landed in the Indian Ocean and near Perth, Australia.

Mercury-Redstone 3 lifts off from LC-5, 10:34:13 EDT, 5 May 1961. (NASA)Alan Bartlett Shepard Jr., Astronaut. (NASA)
At 10:34:13.48 a.m., Eastern Daylight Time ¹ (13:34:13.48 UTC), 5 May 1961, Mercury-Redstone 3 lifted off from Launch Complex 5 at the Cape Canaveral Air Force Station, Cape Canaveral, Florida. On board was a NASA Astronaut, Commander Alan Bartlett Shepard, Jr., United States Navy. Shepard had named his spacecraft Freedom 7.
This was the very first time that an American astronaut had been carried into space aboard a rocket and came 23 days after Soviet Union Cosmonaut Yuri Alekseyevich Gagarin had completed one orbit of the Earth.
During the launch, acceleration reached 6.3 gs. The Redstone’s engine shut down at T+02:21.3, with the rocket having reached a velocity of 7,388 feet per second (2,251.9 meters per second). 10 seconds later, the Mercury spacecraft separated from the Redstone booster. The spacecraft’s maximum speed was 5,134 miles per hour (8,262.4 kilometers per hour). For the next 5 minutes, 4 seconds, Alan Shepard was “weightless.” Freedom 7 reached a peak altitude of 101.2 nautical miles (116.46 statute miles/187.42 kilometers), 0.9 nautical miles (1.7 kilometers) higher than planned.

Alan Shepard’s flight was suborbital. The rocket launched the capsule on a ballistic trajectory. During the flight, Shepard demonstrated the use of manually controlled thrusters to orient the Mercury capsule in three axes.
Freedom 7 began reentry to the atmosphere at T+07:38. Deceleration forces reached 11.0 gs. Shepard manually controlled the vehicle’s attitude, and once correctly oriented for reentry, reverted to automatic control. With the blunt (bottom) end of the spacecraft forward, aerodynamic drag slowed the capsule. A spherical-segment ablative Beryllium heat shield protected the space ship and its passenger.
On reaching the lower atmosphere, the capsule’s speed was reduced by a 63-foot (19.2 meter) diameter ring-sail parachute, and a “landing bag” deployed from the base of the spacecraft to provide an impact cushion. The landing, or “splash down,” took place in the Atlantic Ocean, 263.1 nautical miles (302.8 statute miles/487.3 kilometers) down range, 6.8 nautical miles (7.8 miles/12.6 kilometers) farther than planned. (N. 75° 53′, W. 27° 13.7′)
The total duration of Alan Shepard’s flight was 15 minutes, 28 seconds. All mission objectives were accomplished and no malfunctions occurred.

Eleven minutes after splash down, Commander Shepard was hoisted from the capsule to a hovering U.S. Marine Corps HUS-1 Sea Horse (Sikorsky S-58) helicopter of Marine Helicopter Transport Squadron (Light) 262 (HMR(L)-262).² The helicopter then lifted the Mercury capsule and flew to the nearby U.S. Navy Ticonderoga-class anti-submarine aircraft carrier, USS Lake Champlain (CVS-39). The Mercury capsule was returned to Cape Canaveral for inspection and found to be in excellent condition.

The Mercury capsule will also be lifted from the ocean by the helicopter and carried to USS Lake Champlain (CVS-39). (NASA)USS Lake Champlain (CVS-39), 1 July 1960. (U.S. Navy)
Freedom 7 was the seventh of twenty Mercury capsules built by McDonnell Aircraft Corporation at St. Louis, Missouri, which would also build the follow-on, two-place Gemini spacecraft. It was delivered to Cape Canaveral 9 December 1960.
The space capsule was truncated cone with sides angled 20° from the longitudinal axis. It was 6 feet, 10 inches (2.083 meters) long and had a maximum diameter of 6 feet, 2.50 inches (1.892 meters). The total height of the spacecraft, from the tip of the aero spike to the booster adapter, was 26 feet, 1.26 inches (7.957 meters). At launch, Freedom 7 weighed 4,040.28 pounds (1,832.64 kilograms).

During flight outside the atmosphere, the Mercury spacecraft could be controlled in its pitch, roll and yaw axes by hydrogen peroxide-fueled reaction control thrusters. Both manual and automatic attitude control were available. It could not accelerate or decelerate (except for reentry), so it could not change its orbit.
The spacecraft cabin was pressurized to 5.5 psi (0.38 Bar) with 100% oxygen. The astronaut wore a B.F. Goodrich Mark IV Model 3 Type I full-pressure suit and flight helmet for protection in the event that cabin pressure was lost.

The Redstone MRLV rocket was a redesigned, “man rated” version of the Chrysler Corporation Missile Division-built United States Army M8 Redstone nuclear-armed medium range ballistic missile (MRBM). It was lengthened to provide greater fuel capacity, a pressurized instrumentation section was added, the control systems were simplified for greater reliability, and an inflight abort sensing system was installed. The rocket fuel was changed from hydrazine to ethyl alcohol.
The cylindrical booster was 59.00 feet (17.983 meters) long and 5 feet, 10 inches (1.778 meters) in diameter. The rocket had four guidance fins with rudders mounted at the tail section. (Interestingly, the Redstone stood freely on the launch pad. No hold-downs were used. The guidance fins supported the entire weight of the vehicle.)

The Redstone MRLV was powered by a single liquid-fueled NAA 75-110-A7 rocket engine built by the Rocketdyne Division of North American Aviation, Inc., at Canoga Park, California. The MR-3 A7 produced 78,860 pounds of thrust (350.79 kilonewtons) at Sea Level, and approximately 89,000 pounds (395.89 kilonewtons) in vacuum, burning ethyl alcohol with liquid oxygen.
The total vehicle height of Mercury-Redstone 3, including the booster, adapter, capsule and escape tower, was 83.38 feet (25.414 meters). The total MR-3 vehicle launch weight was 66,098 pounds (29,982 kilograms).

³ From the liftoff of Mercury-Redstone 3 until wheel stop of Space Shuttle Discovery (STS-135), the era of NASA’s Manned Spaceflight Programs lasted 50 years, 2 months, 15 days, 20 hours, 23 minutes, 41 seconds.
4 May 1949: At 5:04 p.m., Central European Time (16:04 UTC), a chartered Avio Linee Italiane Fiat G.212CP airliner, I-ELCE, was descending in very poor weather conditions for landing at the Aeroporto di Torino-Aeritalia (ICAO: LIMA). The flight crew was using a Non-Directional Beacon (NDB) to align itself with the airport’s Runway 28. This beacon provided no vertical course (“glide slope”) guidance.
The airliner crashed into a wall of the Basilica di Superga, located on a 672 meter (2,205 feet) hill east of Turin, and 12 kilometers (7.5 miles) from the runway. All 31 persons on board, the 4-man crew, and 27 passengers, were killed.
Most of the passengers were members of the Grande Torino football club (soccer, as it is known in the United States).
Wreckage of Fiat G.212CP I-ELCE at the Basilica di Superga, Turin, Italy. (Wikipedia)
I-ELCE was a Fiat G.212CP, serial number 5. The G.212 is an all-metal, three-engine, low-wing monoplane with retractable landing gear. The crew consists of a pilot and co-pilot, a flight engineer and a radio operator. It could carry up to 34 passengers. Originally a military transport, the G.212A, the G.212CP variant was produced as a commercial airliner. There was also a cargo version, the G.212TP.
The G.212CP is 75 feet, 8 inches (23.063 meters) long with a wing span of 96 feet, 3 inches (29.337 meters) and overall height of 26 feet, 8 inches (8.128 meters). It has an empty weight of 24,742 pounds (11,223 kilograms) and maximum gross weight of 38,440 pounds (17,436 kilograms).
The G.212CP is powered by three 1,829.4-cubic-inch-displacement (29.978 liter) air-cooled, supercharged, Pratt & Whitney Twin Wasp S1C3-G two-row, 14-cylinder radial engines. These were rated at 1,200 horsepower at 2,700 r.p.m. at Sea Level for takeoff. The maximum continuous rating for normal operation was 1,050 horsepower at 2,550 r.pm., up to 7,500 feet (2,286 meters). Each engine drives a three-bladed constant-speed propeller through a 16:9 gear reduction. The S1C3-G is 48.19 inches (1.224 meters) long, 61.67 inches (1.566 meters) in diameter, and weighs 1,465 pounds (665 kilograms).
The G.212CP has a cruise speed of 160 knots (184 miles per hour/296 kilometers per hour), and maximum speed of 210 knots (242 miles per hour/389 kilometers per hour) at 12,100 feet (3,688 meters). Its service ceiling is 24,600 feet (7,498 meters), and its maximum range is 1,620 nautical miles (1,864 statute miles/3,000 kilometers).
The G.212 was produced from 1947 to 1950. The total number built is variously reported as 19 to 26.

30 April 1962: The Chief Research Test Pilot at NASA’s High Speed Flight Station, Joseph Albert Walker, flew the first North American Aviation X-15 hypersonic research aircraft, 56-6670, on its twenty-seventh flight. This was Flight 52 of the NASA X-15 Hypersonic Research Program. The purpose of this test flight was to explore aerodynamic heating and stability at very high altitudes.
At an altitude of approximately 45,000 feet (13,716 meters) over Mud Lake, Nevada, the X-15 was released from Balls 8, the NB-52B drop ship, at 10:23:20.0 a.m., Pacific Daylight Savings Time.
This NASA image depicts three X-15 flight profiles. Mud Lake, Nevada, is near the right edge of the image. (NASA)
Walker started the Reaction Motors XLR99-RM-1 rocket engine. The planned burn time was 81.0 seconds, but the engine ran slightly longer: 81.6 seconds. Even with the longer burn, the X-15 undershot the planned speed of Mach 5.35 and peak altitude of 255,000 feet (77,724 meters). The actual maximum speed for this flight was Mach 4.94, and maximum altitude, 246,700 feet (75,194 meters). Walker landed on Rogers Dry Lake. The total duration of Flight 52 was 9 minutes, 46.2 seconds.
Even though the peak altitude reached by the X-15 was 8,300 feet (2,530 meters) lower than expected, Joe Walker established a new Fédération Aéronautique Internationale (FAI) World Record for Altitude Gain, Aeroplane Launched from a Carrier Aircraft, of 61,493 meters (201,749 feet).¹
