15 April 1970, 01:09:40 UTC: T plus 077:56:40.0: The Apollo 13 Saturn S-IVB-508 third stage impacted the surface of The Moon north of Mare Cognitum. (S. 2° 33′ 00″, W. 27° 52′ 48″)The S-IVB hit the lunar surface at a velocity of 2.58 kilometers per second (5,771 miles per hour). The impact energy was 4.63 x 1017 ergs (1.04 kiloton).

The impact was detected by seismometers placed on the Moon by Apollo 12 astronauts Pete Conrad and Alan Bean. This was part of the Apollo Lunar Surface Experiments Package, or ALSEP.

The Apollo 12 seismometer was located 135 kilometers (83.9 miles) from the Apollo 13 third stage impact. The signals were used to calibrate the instrument package, which was in service from 1969 to 1977.

The Saturn V third stage was designated Saturn 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 (118,841 kilograms). The third stage had one Rocketdyne J-2 engine which used liquid hydrogen and liquid oxygen for propellant. Itproduced 232,250 pounds of thrust (1,033.10 kilonewtons). 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.

TIROS-1/Thor-Able 148 launches from Launch Complex 17A at Cape Canaveral, Florida, 11:40:09 UTC, 1 April 1960. (NASA)

1 April 1960: TIROS-1, the first successful Earth-orbiting weather satellite, was launched at 6:40:09 a.m. (11:40:09 UTC), from Launch Complex 17A at the Cape Canaveral Air Force Station, Cape Canaveral, Florida, aboard a Thor-Able II liquid-fueled rocket. The satellite’s name is an acronym for Television Infra Red Observation Satellite.

The satellite was placed into a nearly-circular low Earth orbit with an apogee of 417.8 miles (672.4 kilometers) and perigee of 396.2 miles (637.6 kilometers). It is still in orbit and circles the Earth once every 1 hour, 37 minutes, 42 seconds. TIROS-1 remained operational for 78 days. It is still in orbit.

TIROS-1 was built of aluminum and stainless steel. It had a diameter of 3 feet, 6 inches (1.067 meters) and height of 1 foot, 7 inches (0.483 meters.) The satellite weighed 270 pounds (122.47 kilograms). Two television cameras were installed on the satellite. They received electrical power from storage batteries charged by 9,200 solar cells. Images were stored on magnetic tape, then transmitted when in range of a ground receiving station. The first image, which showed large-scale cloud formations, was transmitted the day of the launch.

The launch vehicle, Thor 148, consisted of a liquid-fueled Douglas Aircraft Company Thor DM-18A first stage (based on the SM-75 intermediate range ballistic missile) and an Aerojet Able-II second stage, which was developed from the Vanguard rocket series. The Thor-Able was 91 feet (27.8 meters) tall and 8 feet (2.44 meters) in diameter. It weighed 113,780 pounds (51,608 kilograms). The first stage was powered by a Rocketdyne LR79-7 rocket engine which burned RP-1 and liquid oxygen. The engine produced 170,560 pounds of thrust (758.689 kilonewtons) and burned for 165 seconds.

The Able-II second stage was powered by an Aerojet AJ-10 engine which produced 7,800 pounds of thrust (34.696 kilonewtons). The propellant was a hypergolic combination of nitric acid and UDMH (hydrazine). It burned for 115 seconds.

There were sixteen Thor-Able two-stage rockets launched. TIROS-1 was placed in orbit by the last of that series.

Apollo-Saturn IB AS-201 launch from Pad 34, Kennedy Space Center, 26 February 1966. (NASA)

26 February 1966: AS-201, a Saturn IB launch vehicle, carried the first complete Block 1 Apollo Command and Service Module on a 37 minute, 19.7 second unmanned suborbital test flight. Liftoff was at 11:12:01 a.m., EST, from Launch Complex 34 at the Kennedy Space Center, Cape Canaveral, Florida.

Department of Special Collections, M. Louis Salmon Library, University of Alabama, via heroicrelics.org

This flight was a demonstration of the combined Apollo Command Module and the Service Module. The second production Apollo capsule, CM-009, and the first production service module, SM-009, were launched by the first Saturn IB, SA-201.

The Apollo capsule reached a maximum altitude of 305.8 miles (492.1 kilometers) and landed near Ascension Island in the South Atlantic Ocean, 5,267 miles (8,477 kilometers) from Cape Canaveral. (S. 8.18°, W 11.15°) Total duration of the flight was 37 minutes, 19.7 seconds.

The Apollo spacecraft was recovered by USS Boxer (LPH- 4).

The flight was successful, though several problems occurred. These were identified and corrected on the following production vehicles.

The Apollo command module of AS-201 was Spacecraft 009. It was a Block I capsule. The Apollo was a conical space capsule designed and built by North American Aviation to carry a crew of three on space missions of two weeks or longer.

The Saturn IB consisted of an S-IB first stage and an S-IVB second stage. The S-IB was built by Chrysler Corporation Space Division at the New Orleans Michoud Assembly Facility. It was powered by eight Rocketdyne H-1 engines, burning RP-1 and liquid oxygen. Eight Redstone rocket fuel tanks containing the RP-1 fuel surrounded a Jupiter rocket tank containing the liquid oxygen. The S-IB stage is 80 feet, 2 inches (24.435 meters) long, with a diameter of 21 feet, 5 inches (6.528 meters). The empty weight of this stage was 85,000 pounds (38,555 kilograms). Fully fueled, it weighed 498,099 pounds (225,934 kilograms). Total thrust of the S-IB stage was 1,600,000 pounds (7,117,155 Newtons) and it carried sufficient propellant for 2 minutes, 35 seconds burn time. This would lift the vehicle to an altitude of  37 nautical miles (69 kilometers).

The Douglas Aircraft Company-built S-IVB second stage was assembled at Huntington Beach, California. It was powered by one Rocketdyne J-2 engine, also fueled by liquid hydrogen and liquid oxygen. The S-IVB is 60 feet, 1 inch (18.313 meters) long with a diameter of 21 feet, 8 inches (6.604 meters). The second stage had an empty weight of 28,400 pounds (12,882 kilograms) and gross weight was 261,900 pounds (118,796 kilograms). The single engine produced 232,250 pounds of thrust (1,033,100 Newtons) and and its burn time was 7 minutes, 55 seconds.

The AS-201 223 feet, 6 inches (68.123 meters). The total vehicle weight was 1,320,220 pounds (598,842 kilograms). It was capable of launching a 46,000 pound (20,865 kilogram) payload to Earth orbit.

After being recovered, the AS-201 Apollo command module was used for drop tests. It is at the Strategic Air and Space Museum, Ashland, Nebraska.

20 February 1962: At 9:47:39 a.m., Eastern Standard Time, NASA’s Mercury-Atlas 6 lifted off from Launch Complex 14, Cape Canaveral Air Force Station, Cape Canaveral, Florida. This was the third launch of a manned Mercury spacecraft, and the first time that an Atlas rocket had been used.

Aboard the spacecraft was Lieutenant Colonel John Herschel Glenn, Jr., United States Marine Corps, an experienced fighter pilot and test pilot.

In his post-flight mission report, Glenn wrote,

When the countdown reached zero, I could feel the engines start. The spacecraft shook, not violently but very solidly. There was no doubt when lift off occurred, When the Atlas was released there was an immediate gentle surge to let you know you were on your way.

2 minutes, 9.6 seconds after liftoff, the booster engines cut of and were jettisoned. 23 seconds later, the escape tower, no longer needed, was also jettisoned. The Atlas sustainer engine continued to burn until T+00:05:01.4. The spacecraft had now reached 17,544 miles per hour (28,234 kilometers per hour) and was in an elliptical orbit around the Earth. At T+00:05:03.6 the Mercury spacecraft separated from the Atlas booster. During the climb to orbit, John Glenn experienced a maximum acceleration of 7.7 gs.

Glenn’s orbit had an apogee of 162.2 statute miles (261 kilometers) and perigee of 100 miles (161 kilometers). The orbit was inclined 32.54° relative to Earth’s orbital plane. Friendship 7 completed an orbit every 88 minutes, 29 seconds.

Analysis showed that the Atlas had placed Friendship 7 in orbit at a velocity with 7 feet per second (2.1 meters per second) less than nominal. However, computer analysis showed that the orbital trajectory was good enough for nearly 100 orbits.

The Mercury spacecraft, Friendship 7, was built by McDonnell Aircraft Corporation, St. Louis, Missouri. It was the 13th Mercury capsule built. Designed to carry one pilot, it could be controlled in pitch, roll and yaw by steam thrusters fueled by hydrogen peroxide. The Mercury was 7 feet, 2.83 inches (2.206 meters) long, not including its retro rocket pack. The spacecraft was generally conical, and had a maximum diameter of 6 feet, 2.50 inches (1.885 meters). It weighed 2,700 pounds (1,224.7 kilograms) at launch.

The rocket, a “1-½ stage” liquid-fueled Atlas LV-3B, number 109-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 (118,000 kilograms) and could place a 3,000 pound (1,360 kilogram) payload into low Earth orbit.

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.

17 February 1996, 20:43:27 UTC: The National Aeronautics and Space Administration/Johns Hopkins University Applied Physics Laboratory space probe NEAR—Near Earth Asteroid Rendezvous—was launched aboard a three-stage McDonnell Douglas Delta II rocket from Launch Complex 17 at the Cape Canaveral Air Force Station, Cape Canaveral, Florida.

The purpose of the 5-year-long mission was to study several near-Earth asteroids, including 253 Mathilde and 433 Eros.

The space probe was renamed NEAR Shoemaker in honor of Eugene Merle (“Gene”) Shoemaker, Ph.D., a well-known planetary scientist who dies in a vehicle collision in Australia, 18 July 1997.

NEAR Shoemaker made its closest approach to 253 Mathilde on 27 June 1997, passing the asteroid at a distance of approximately 1,200 kilometers (746 miles) at 35,748 kilometers per hour (22,213 miles per hour). More than 500 photographic images, along with sensor data, were transmitted to Earth. The space probe’s main engine was then ignited to send it on a new trajectory to 433 Eros.

NEAR Shoemaker was placed into an orbit around 433 Eros on 14 February 2000. NEAR Shoemaker photographed and studied the asteroid for nearly a year, and then on 12 February 2001, after completing 230 orbits, made a soft landing on its surface.

The McDonnell Douglas Delta II 7925-8 Orbital Launch Vehicle is a three-stage, liquid-fueled rocket. It is 125 feet, 4 inches (38.201 meters) long, 8 feet, 0 inches (2.438 meters) in diameter, and weighs approximately 480,000 pounds (217,724 kilograms). At the time, the Delta II was the smallest rocket used to launch a planetary mission.

The first stage is a Thor/Delta XLT-C (“long-tank Thor”), which is 85 feet, 5½ inches (26.048 meters) long, 8 feet, 0 inches (2.438 meters) in diameter, and weighs 224,600 pounds (101,877 kilograms) when fully fueled. The stage is powered by one liquid-fueled Rocketdyne RS-27A rocket engine, rated at 236,992 pounds of thrust (1,054.193 kilonewtons). Fueled with 10,000 gallons (37,854 liters) of RP-1/LOX propellant and oxidizer, the engine has 4 minutes, 25 second burn time.

Surrounding the Thor are nine Alliant Techsytems (ATK) GEM-40 (Graphite-Epoxy Motor) solid fuel boosters. They are 42 feet, 6 inches (12.957 meters) long, and 3 feet, 4 inches (1.018 meters) in diameter, and weigh 28,671 pounds ( kilograms). Each booster produces 110,800 pounds of thrust (492.863 kilonewtons), and have 1 minute, 4 second burn time. Six of the nine GEM-40s are ignited at launch, and the remaining three ignite after the first six burn out.

The second stage is a McDonnell Douglas Delta K, which is 19 feet, 3 inches (5.867 meters) long, 8 feet, 0 inches (2.438 meters) in diameter, and weighs 15,331 pounds ( kilograms). The Delta K is powered by one Aerojet AJ10-118K liquid-fueled rocket engine which produces 9,800 pounds of thrust (43.593 kilonewtons). It has a 7 minute, 11 second burn time.

The third stage is a McDonnell Douglas PAM-D (Payload Assist Module), powered by a Thiokol Propulsion Star 48B solid rocket motor, which produces 15,000 pounds of thrust (66.723 kilonewtons), and has a burn time of 1 minute, 27 second burn time.

The NEAR space probe was designed and built by the Johns Hopkins University Applied Physics Laboratory. The probe was equipped with an X-ray/gamma ray spectrometer, near-infrared imaging spectrometer and a multi-spectral CCD imaging camera, laser rangefinder and magnetometer. NEAR was 9 feet, ¼-inch (2.749 meters) long and weighed 1,803 pounds (817.8 kilograms). Power was supplied by four solar panels, capable of generating 400 watts.The main engine produced 450 Newtons (101 pounds) of thrust using hydrazine and nitrogen tetroxide. A system of 11 hydrazine thrusters and 4 reaction wheels  were used attitude control.
