"On Jan. 27, 1967, tragedy struck on the launch pad at Cape Kennedy during a preflight test for Apollo 204 (AS-204). The mission was to be the first crewed flight of Apollo, and was scheduled to launch Feb. 21, 1967. Astronauts Virgil Grissom, Edward White and Roger Chaffee lost their lives when a fire swept through the command module." - Nasa

"The Apollo Lunar Module (LM) was a two-stage vehicle designed by Grumman to ferry two astronauts from lunar orbit to the lunar surface and back. The upper ascent stage consisted of a pressurized crew compartment, equipment areas, and an ascent rocket engine. The lower descent stage had the landing gear and contained the descent rocket engine and lunar surface experiments. LM 2 was built for a second unmanned Earth-orbit test flight. Because the test flight of LM 1, performed as part of the Apollo 5 mission, was so successful, a second unmanned LM test mission was deemed unnecessary. LM-2 was used for ground testing prior to the first successful moon landing mission. In 1970 the ascent stage of LM-2 spent several months on display at the "Expo '70" in Osaka, Japan. When it returned to the United States, it was reunited with its descent stage, modified to appear like the Apollo 11 Lunar Module "Eagle," and transferred to the Smithsonian for display." - National Air and Space Museum

This started the space and cause all of the apollo missiosn. "The N-1 rocket suffered from critical technical problems that doomed Soviet efforts to land a person on the Moon by 1970. In the first launch attempt in February 1969, an engine fire caused the rocket to shut down and crash a minute after lift-off. The second test, in July 19 lift-off, fell onto the launch pad, and exploded. This accident destroyed the launch site and any hope that the Soviets could reach the Moon ahead of the United States. Three weeks later, the crew of Apollo 11 landed on the Moon. Ten N-1s were built. Four were destroyed in failed test launches, and the others were dismantled when the program was canceled in 1974, and the Soviet crewed lunar program passed into oblivion." - National Air and Space Museum
