23 Ιαν 2017 · But, infamously, a fire in the pure oxygen environment of the Apollo 1 spacecraft could not be compensated for—even by arguably NASA's best test pilot, Gus Grissom, veteran astronaut Ed...
Apollo 1, initially designated AS-204, was planned to be the first crewed mission of the Apollo program, [1] the American undertaking to land the first man on the Moon. It was planned to launch on February 21, 1967, as the first low Earth orbital test of the Apollo command and service module.

27 Ιαν 2012 · After the Apollo 1 fire, a tragedy that killed three astronauts in 1967, NASA changed its thinking about space capsule design and safety forever.
13 Απρ 2019 · NAA engineers knew that in a pure oxygen environment, a single spark could turn into a raging fire with explosive consequences, and they made their concerns known to NASA. The space agency countered that the risks of a fire in the crew cabin was minimal because it was a low-pressure environment.
Fueled by an exhaustive and fast-burning oxygen-rich atmosphere, the Apollo 1 command capsule ignited from the inside out. Within minutes its crew, astronauts Virgil “Gus” Grissom, Ed White and Roger Chaffee, lost their lives to the blaze.
13 Φεβ 2020 · Much like the previous Gemini crafts, Apollo 1, too, was designed to be a pure oxygen capsule, since it required lighter environmental conditions than an oxygen-nitrogen mixture.
