If things go as hoped and planned, NASA's Artemis I, an uncrewed mission to circle the moon and return to Earth, will launch early Wednesday morning. Here's what you need to know. And see the link to learn about Huntsville's role:
From its beginning in 1960, engineers at Redstone Arsenal and Marshall Space Flight Center in Huntsville have led every major rocket propulsion development in American space, powering the launches of the first U.S. satellite, first astronaut in space, and first men to the moon.
But Huntsville’s rocket history predates NASA’s creation in July of 1958 and starts with the Army Jupiter C liquid-fueled rocket built under the leadership of Wernher von Braun’s team of German rocket engineers. It launched Explorer 1, America’s first satellite, Jan. 31, 1958.The fuel that lifted the Jupiter C. Redstone booster was liquid oxygen and alcohol. After the first stage was modified, the rocket used a blend of propellants more powerful than the previous ethyl alcohol.
Marshall developed the Saturn V’s F-1 engines from testing to flight and the second stage J-2 engines from concept to flight.The space shuttle era came after Saturn and Marshall led development of the Space Shuttle Main Engine , the large orange liquid fuel tank, and the solid rocket boosters. Artemis will also be lifted by Solid Rocket Boosters, one on each side, powered by ammonium perchlorate as an oxidizer and aluminum powder as fuel. Artemis is using upgraded versions.
