“The fire-in-the-hole abort was the most critical test of the mission and one we had to accomplish successfully prior to a manned mission.” Gene Kranz – Flight Director Apollo 5

“…our building’s shaking here. Our building’s shaking! Oh it’s terrific, the building’s shaking! This big blast window is shaking! We’re holding it with our hands! Look at that rocket go into the clouds at 3000 feet!…you can see it…you can see it…oh the roar is terrific!…”  Walter Cronkite – Apollo 4 launch.

“The S-II stage was a nightmare the minute it was conceived, and it only got worse from there. During the course of its creation, it would grind up people and careers the way the transcontinental railway devoured laborers.  Though the methods and materials used to build the S-II were reasonably well known, nobody had ever tried to apply them on such a titanic scale.  Originally, it was to be somew...

The structural efficiency of the S-II stage, in terms of the weight and pressures taken by its extra-thin walls, was comparable only to the capacity of one of nature’s most refined examples of structural efficiency, the egg.  

The primary objectives of the Surveyor program, were to support the Apollo landings by: (1) developing and validating the technology for landing softly on the Moon; (2) providing data on the compatibility of the Apollo design with conditions encountered on the lunar surface; and (3) adding to the scientific knowledge of the Moon.

A total of five Lunar Orbiter missions were launched by the US in 1966 through 1967.  The purpose of the lunar orbiter series was to photograph the moon’s surface for selection and verification of safe landing sites for the Surveyor and Apollo missions.

After 1957, the Soviets became accustomed to achieving “world firsts” in space accomplishments. Nevertheless, 10 years later they were not confident that they could pull off the world’s first fully automatic rendezvous and docking of two un-piloted Soyuz spacecraft.  At the time the chance for success was estimated at only 50/50.

“It seemed that the nearby and mysterious planet was resorting to tricks to hide the secrets kept beneath its cover of clouds. As the probe drew nearer, Venus’ gravitational field increased its speed. The Doppler effect altered the wavelength of the signals received on Earth. The radio operators needed to be particularly vigilant so that the information sent from the station consistently landed in...

“It’s a terrible scene. Komarov burned up. All the instruments burned. We must quickly find out what prevented the main parachute from unlatching.” Chief Designer Mishin after he arrived at the Soyuz 1 crash site.

“I was the last one to see him alive and I told him ‘See you soon!’” Yuri Gagarin, recalls bidding farewell to his friend Kamarov in Soyuz 1.

With the success of Kosmos 146 and in spite of the failures of the first three 7K-Ok’s it was now time to plan for a Soyuz manned mission. The planned involved the launch and docking of two piloted Soyuzes. Soyuz 7K-OK production model number 4 was assigned the role of the active vehicle. The active vehicle was supposed to carry one cosmonaut into earth orbit. Twenty-four hours later, vehicle No....

Chief Designer Mishin proposed a two-launch “stopover” scenario for the piloted flight to the moon. This was similar to one of NASA’s earth orbit rendezvous modes to reach the moon. The gist of the plan was, the UR-500K would insert the 7K-L1 into orbit with no crew. Then the R7 derivative Semyorka would launch the 7K-OK carrying two cosmonauts. If everything went well on the two vehicles, they wo...

After the uncertain days of February 1967, NASA officials began to realize that a recovery from the tragedy was under way. Through hard work and problem solving, morale of Nasa personnel started to improve…

What went wrong?  Even years after the investigators began to sift through the wreckage of Apollo 1 piece by piece, no one could say exactly.  But within weeks the general picture became clear:  The fire was a disaster waiting to happen.

The tragedy of Apollo 1 was widely reported in the Soviet Union. The Soviets sent condolences and letters to the families of the men who had died. But, the Soviet Press criticized the US for an overzealous attempt to send men to the moon.

When Deke Slayton and Stu Roosa arrived at pad 34 they saw ambulances waiting in vain at the base of the launch tower.  They boarded the small elevator and rode to level A-8, 218 feet up, and headed across the swing arm to the clean room…

The “Plugs Out” test scheduled for Jan 27, 1967 was not the first time that spacecraft 12 had been put through a simulated run with people on board…

“On my honor I will do my best, To do my duty to God and my country and to obey the Scout Law; To help other people at all times;  To keep myself physically strong, mentally awake, and morally straight.” The Boy Scout Oath.

“So the reason I took those symbols was that I think this was the most important thing I had going for me, and I felt that while I couldn’t take one for every religion in the country, I could take the three I was most familiar with.”  Ed. White

While flight-preparation crews were having problems, Grissom, White, and Chaffee were finding bottlenecks in training activities. The chief problem was keeping the Apollo mission simulator current with changes being made in spacecraft 012.

As Procedures Officer, Kranz was put in charge of integrating Mercury Control with the Launch Control Team at Cape Canaveral, Florida, writing the “Go/NoGo” procedures that allowed missions to continue as planned or be aborted, along with serving as a sort of switchboard operator using teletype between the control center at Cape Canaveral and the agency’s fourteen tracking stations and two trackin...

At the beginning of the Apollo program, Kraft retired as a flight director to concentrate on management and mission planning. In 1972, he became director of the Manned Spacecraft Center, following the path of his mentor Robert Gilruth.

Christopher Columbus Kraft Jr. was Born on February 28, 1924 in a town that no longer exist, Phoebus, Virginia. The town has now been engulfed by Hampton, Virginia. Kraft was named after his father, Christopher Columbus Kraft, who was born in New York City in 1892 near Columbus Circle at 8th ave. and 59th street.

Apollo Saturn 201 employed the Saturn IB launch vehicle, which  was the up-rated version of the Saturn I rocket flown in ten earlier Saturn-Apollo missions. It featured an upgrade of the first stage engines to increase thrust from 1,500,000 lb-ft of thrust to 1,600,000 lb-ft. The second stage was the S-IVB.  This stage used a new liquid hydrogen-burning J-2 engine which would also be used on the S...

“Some of those guys came in figuring, “I’ll write my textbooks and my thesis and teach [university courses] and I’ll come by twice a week and be an astronaut.” Well, that didn’t work …. We were devoting our lives to this whole thing, and you couldn’t devote anything less, I don’t care what your discipline was.”
