This week in 1963, the Saturn I SA-4 rocket launched from NASA’s Kennedy Space Center. The uncrewed suborbital test flight was the final of four tests of the Saturn I first, or S-I, stage that employed a cluster of eight H-1 engines. After 100 seconds into flight, a preset timer cut off engine number 5 as planned to test the “engine out” capability. Fuel was successfully routed to the other seven engines and the flight continued. Managed by NASA’s Marshall Space Flight Center, the Saturn I vehicle and its follow-on, the Saturn IB, served as test bed rockets for the larger and more powerful Saturn V that would eventually carry the first humans to the Moon. Today, Marshall is playing a vital role in the Artemis program by developing the Space Launch System, the backbone of NASA’s exploration plans and the only rocket capable of sending humans to the Moon and Mars.
