This week in 1964, the Saturn I SA-7 mission launched from NASA’s Kennedy Space Center. The second stage of the Saturn I, the S-IV, consisted of a circular cluster of six RL-10 engines, which employed liquid oxygen and liquid hydrogen as propellants to produce a combined thrust of 90,000 pounds. Here, the Saturn I S-IV stage of the SA-7 rocket is being prepared for shipment to Cape Canaveral, Florida, for its Sept. 18, 1964, launch. Today, Marshall is developing NASA’s Space Launch System, the most powerful rocket ever built, capable of sending astronauts to Mars and deeper into space than ever before.
