17 April 1970: Apollo 13 splashed down in the Pacific Ocean at S. 21° 38′ 24″, W. 165° 21′ 42″, southwest of American Samoa. The landing was just 4 miles (6.4 kilometers) from the recovery ship, USS Iwo Jima (LPH-2).

With their spacecraft crippled by an internal explosion on 13 April, the planned lunar landing mission had to be aborted. Astronauts James A. Lovell, Jr., John L. Swigert, Fred W. Haise, Jr., worked continuously with engineers at Mission Control, Houston, Texas, to overcome a series of crises that threatened their lives.

13 April 1970: At 10:07:53 p.m. Eastern Standard Time (mission elapsed time 55:54:53), while Apollo 13 and its crew, James A. Lovell, Jr., John L. Swigert and Fred W. Haise, were approximately 200,000 miles (322,000 kilometers) from Earth enroute to a landing at the Fra Mauro Highlands on The Moon, an internal explosion destroyed the Number 2 oxygen tank¹ in the spacecraft’s Service Module. The Number 1 tank was also damaged. Two of three fuel cells that supplied electrical power to the spacecraft failed.

Jack Swigert radioed Mission Control: “I believe we’ve had a problem here.” ²

Mission Control: “This is Houston. Say again, please.

Jim Lovell: “Houston, we’ve had a problem. Main B Bus undervolt.

With oxygen supplies depleted and power failing, the lunar landing mission had to be aborted, and the three-man crew evacuated the Command Module and took shelter in the Lunar Module.

This was a life-threatening event.

The story of Apollo 13 and its crew and their journey home is well known. The 1995 Ron Howard/Universal Pictures film, “Apollo 13,” takes some artistic license, but is generally accurate and realistic.

Mission Controller Gene Kranz is known for his statement, "Failure is not an option.) NASA Apollo 13 Image Library Image S70-35139)

Five years before Apollo 13 was launched, an engineering decision had been made to increase the spacecraft electrical system from 28 volts to 65 volts. This required that every electrical component on the vehicle had to be changed to accommodate the increased power. The after-accident investigation found that the team that designed the cooling fans for the oxygen tanks was never informed of the change.

During the actual flight, the wiring inside the tank heated to approximately 1,000 °F. (538 °C.), and in the pressurized pure oxygen, the insulation caught fire. The tank, originally installed on Apollo 10, had been dropped when it was removed for modification. It was repaired and later used on Apollo 13, however, it had been weakened by the damage. The extreme pressure caused by the heat of the burning electrical wiring in the containment caused the tank to rupture.

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.

15 December 1965: At 13:37:26 UTC, Gemini 6A, with NASA astronauts Captain Walter M. Schirra, Jr., United States Navy and Major Thomas P. Stafford, United States Air Force, on board, lifted off from Launch Complex 19 at the Cape Kennedy Air Force Station, Cape Kennedy, Florida. During its fourth orbit, Gemini 6A rendezvoused with Gemini 7, carrying Major Frank F. Borman II, USAF, and LCDR James A. Lovell, Jr., USN.

This was the first time that two manned space vehicles had rendezvoused in Earth orbit.

The two spacecraft remained together for 5 hours, 19 minutes before separating to a distance of approximately 10 miles (16 kilometers).

Gemini 7 had been in orbit since 4 December. Gemini 6, then 6A, had been postponed several times before finally launching on 15 December. It would return to Earth the following day, landing in the North Atlantic Ocean. Gemini 7 remained in orbit until 18 December.

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 Marietta Corporation SM-68B intercontinental ballistic missile. It was assembled at Martin’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.

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.
