Apollo 1
Definition
Apollo 1 (also known as AS-204) was the first crewed mission of NASA's Apollo program, intended as a test flight for the command and service module. Tragically, on January 27, 1967, a fire erupted during a launchpad rehearsal, killing astronauts Virgil 'Gus' Grissom, Edward White, and Roger Chaffee due to a pure-oxygen atmosphere and design flaws.
The designation symbolizes a pivotal moment in space exploration history, leading to major safety overhauls that enabled the success of subsequent Apollo missions.
