28 January 1986, 11:38:00 a.m. (EST): The Space Shuttle Challenger (OV-99) lifted off from Launch Complex 39B at the Kennedy Space Center, Cape Canaveral, Florida, on Mission STS-51L.

At liftoff, an O-ring seal between segments of the right Solid Rocket Booster (SRB) began leaking. Superheated gases breached the seal and began to burn laterally.

“At 58.778 seconds into powered flight, a large flame plume is visible just above the SRB exhaust nozzle indicating a breach in the motor casing.” (NASA)

The venting rocket exhaust burned through the SRB attachment strut and into the liquid hydrogen tank in the lower section of the External Tank. The aft portion of the liquid hydrogen tank failed and drove the tank vertically upward into the liquid oxygen tank. Both tanks ruptured and the propellants detonated.

1 minute, 13 seconds after liftoff, Challenger was accelerating through Mach 1.62 (1,069 miles per hour, 1,720 kilometers per hour) at approximately 46,000 feet (14,020 meters) when the explosion of the external tank caused the space shuttle to suddenly veer away from its flight path. The shuttle was subjected to aerodynamic forces far beyond its design limits and it was torn apart.

The crew cabin, with its seven astronauts aboard, broke away from the disintegrating shuttle assembly and continued upward for another 25 seconds to approximately 65,000 feet (19,080 meters), then began a long fall to the ocean below.

2 minutes 45 seconds after the explosion, the cabin impacted the surface of the Atlantic Ocean at 207 miles per hour (333 kilometers per hour). The entire crew was killed.

27 January 1967: During a “plugs out” test of the Apollo 1 Command Module, two weeks ahead of the scheduled launch of the Apollo/Saturn 1B AS-204—the first manned Apollo Program space flight—a fire broke out in the pressurized pure oxygen environment of the capsule  and rapidly involved the entire interior.

The pressure rapidly built to 29 pounds per square inch (200 kPa) and 17 seconds later, at 23:31:19.4 UTC, the capsule ruptured.

The three astronauts, Lieutenant Colonel Virgil I. Grissom, United States Air Force, Lieutenant Colonel Edward H. White II, United States Air Force, and Lieutenant Commander Roger B. Chaffee, United States Navy, were killed.

Eugene Andrew Cernan (The Provi of 1952)

Eugene Andrew Cernan was born at Chicago, Illinois, 14 March 1934. He was the second child of Andrew George Cernan, a manufacturing foreman, and Rose A. Cihlar Cernan. Gene Cernan graduated from Proviso East High School, Maywood, Illinois, in 1952.

Cernan entered Purdue University, West Lafayette, Indiana, as an engineering student. He was a midshipman in the U.S. Navy Reserve Officers Training Corps (R.O.T.C.), and a member of the Phi Gamma Delta fraternity (ΦΓΔ) , serving as treasurer. He was also president of the Quarterdeck Society and the Scabbard and Blade, and a member of the Phi Eta Sigma (ΦΗΣ) honor society and Tau Beta Pi (ΤΒΠ) engineering honor society. He served on the military ball committee and was a member of the Skull and Crescent leadership honor society. During his Midshipman Cruise in 1955, Cernan served aboard the Worcester-class light cruiser USS Roanoke (CL-145). Cernan graduated from Purdue in 1956 with Bachelor of Science Degree in Electrical Engineering (B.S.E.E.).

Cernan was commissioned as an ensign, United States Navy, 2 June 1956, and was assigned to flight training. He was promoted to lieutenant (junior grade), 1 December 1957. Lieutenant Cernan completed flight school and qualified as Naval Aviator. He was assigned to Attack Squadron 126 (VA-126) at NAS Miramar, San Diego, California, flying the North American Aviation FJ-4B Fury. On 1 June 1960, Cernan was promoted to the rank of lieutenant.

Cernan earned a Master of Science Degree in Aeronautical Engineering from the U.S. Naval Postgraduate School at Monterey, California, in 1963.

In October 1963, Lieutenant Cernan was selected as an Astronaut for the National Aviation and Space Administration (NASA). He was one of 14 members of NASA Astronaut Group 3, which was announced 18 October 1963.

Gene Cernan was promoted to the rank of commander, United States Navy, 3 June 1966. He flew as pilot of Gemini IX-A, 3-6 June 1966. (Thomas P. Stafford was the command pilot.) The mission included a rendezvous with a Lockheed Agena target vehicle. A planned docking with the Agena could not be carried out because the docking shroud had failed to deploy correctly. On 6 June, Cernan conducted an “EVA” (Extravehicular Activity, of “space walk”). During the 2 hour, 7 minute EVA, numerous difficulties were encountered.

Cernan was promoted to the rank of captain, United States Navy, 10 July 1970. He was next assigned as the backup to Alan B. Shepard as mission commander for Apollo 14.

On 23 January 1971, Cernan was flying a Bell Model 47G-3B-1 helicopter, NASA 947 (N947NA, serial number 6665), on a proficiency flight, when it crashed in the Indian River near Malabar, Florida. The helicopter was destroyed and Cernan was slightly injured. The official investigation reported the cause as a “misjudgement in estimating altitude.” In his autobiography, Cernan wrote,

“Without ripples, the water provided no depth perception and my eyes looked straight through the clear surface to the reflective river bottom. I had lost sight of the water.”

John Glenn, one of the original seven astronauts selected by NASA for Project Mercury, was a personal hero of mine. As a young boy growing up in Southern California, less than three miles from Rocketdyne’s engine test stands in Santa Susana, I followed the progress of all the astronauts. I recall having a map pinned to my wall, showing the orbital path of Friendship 7 as Glenn made his historic three orbits of the Earth. All of the astronauts, and the X-15 test pilots at Edwards, were heroes to me, but for some reason, John Glenn was special.

John H. Glenn, Jr., Pilot. (John Glenn Archives, Ohio State University)

John Herschel Glenn, Jr., was born at Cambridge, Ohio, 18 July 1921, the first of four children of John Herschel Glenn, a plumber, and Clara Teresa Sproat Glenn. The Glenn family resided in New Concorde, Ohio. Glenn attended New Concord High School, graduating in 1939, and then enrolled at Muskingum College, also in New Concord, where he majored in engineering. While in college, he learned to fly.

Soon after the United States entered World War II, John Glenn enlisted in the United States Navy as a Naval Aviation Cadet, 28 March 1942. He transferred to the Marine Corps while still in flight training, and after qualifying as a Naval Aviator, was commissioned as a Second Lieutenant, U.S. Marine Corps Reserve, 16 March 1943.

On 6 April 1943, Lieutenant Glenn married Miss Anna Margaret Castor, also from New Concorde. They would have two children, Carolyn Ann Glenn and John David Glenn.

In October 1943, Glenn was promoted to First Lieutenant. Initially assigned as a transport pilot flying the Douglas R4D-1 Skytrain with Marine Utility Squadron 315 (VMJ-315) in the Pacific, he was transferred to Marine Fighter Squadron 155 (VMF-155). He flew 59 combat missions with the Chance Vought F4U Corsair in the Marshall Islands.

In 1945, Glenn was assigned to Marine Fighter Squadron 218 (VMF-218), again flying an F4U-4 Corsair, patrolling China with the 1st Marine Division. Lieutenant Glenn was promoted to the rank of Captain in July 1945.

In 1946, Captain Glenn, was transferred from the USMCR to the regular Marine Corps, retaining his temporary rank. On 7 August 1947, the rank of Captain was made permanent.

Captain Glenn served as an advanced flight instructor at NAS Corpus Christi, Texas, from June 1948 to December 1950. With the Korean War, Glenn was assigned to Marine Fighter Squadron 311 (VMF-311), which flew the Grumman F9F-2 Panther.

Captain Glenn few 63 combat missions with VMF-311. He was promoted to the rank of Major, 28 June 1952. He served as an exchange officer with the U.S. Air Force, flying a North American Aviation F-86F Sabre with the 25th Fighter Interceptor Squadron, 51st Fighter Interceptor Wing at K-13, an air base at Suwon, Republic of Korea. In July 1953, Glenn shot down three enemy Mikoyan-Gurevich MiG 15 jet fighters.

Major Glenn trained at the U.S. Navy Test Pilot School at NATC Patuxent River, Maryland, in 1954, and from 1956 to 1959, was assigned to the Bureau of Aeronautics, Fighter Design Branch.

On 16 July 1957, Major Glenn flew a Chance Vought F8U-1P Crusader from NAS Los Alamitos, on the coast of southern California, to Floyd Bennet Field, Brooklyn, New York, in 3 hours, 23 minutes, 8.4 seconds, averaging 725.25 miles per hour (1,167.18 kilometers per hour). Thomas S. Gates, Jr., Secretary of the Navy, presented Major Glenn the Distinguished Flying Cross.

Major Glenn was promoted to the rank of Lieutenant Colonel, 1 April 1959. He was selected as an Astronaut with the National Aeronautics and Space Administration’s Project Mercury and joined the NASA Space Task group at the Langley Research Center. Lieutenant Colonel Glenn was the senior officer and the oldest member of “The Mercury 7.”

At 9:47:39 a.m., Eastern Standard Time (14:47:39 UTC), 20 February 1962, 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 Mercury was John Glenn, making his first space flight. He had named the capsule Friendship 7. Alan Shepard and Gus Grissom had each made a suborbital flight, but Glenn was going into Earth orbit.

Each orbit took 88 minutes, 19 seconds. The spacecraft’s altitude ranged from 100 miles (161 kilometers) to 162.2 miles (261 kilometers).

During the 4 hour, 55 minute, 23 second flight, Friendship 7 orbited the Earth three times, and traveled 75,679 miles (121,794 kilometers). John Glenn was the first American astronaut to orbit the Earth. (Cosmonaut Yuri Gagarin had orbited the Earth 12 April 1961.)

After re-entry, the capsule parachuted into the Atlantic Ocean, splashing down only six miles from the recovery ship, USS Noa (DD-841).

When the Space Task Group was moved to the Manned Spacecraft Center at Houston, Texas, in 1962, John Glenn was involved in the layout and design of spacecraft cockpits and function of controls. On 16 January 1964, John Glenn resigned from NASA. He was promoted to the rank of Colonel in October 1964, then he retired from the Marine Corps 1 January 1965, after 23 years of military service.

Glenn worked in private industry for several years before beginning a career in politics. In 1974, he was elected to the United States Senate, representing his home State of Ohio. He served in the United States Congress from 24 December 1974 to 3 January 1999.

John Glenn wasn’t finished with spaceflight, though. From 29 October to 7 November 1998, Senator Glenn served as a NASA Payload Specialist aboard Space Shuttle Discovery (OV-103) during Mission STS-95. At the age of 77 years, John Glenn was the oldest person to fly in space.

During his two space flights, John Glenn orbited the Earth 137 times. His total time in space is 10 days, 49 minutes, 25 seconds (240:49:25).

In late November 2016, Glenn was admitted to Ohio State University Wexner Medical Center at Columbus, Ohio. He died there, 8 December 2016, at the age of 95 years.

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.
