This week in 1963, the Saturn I SA-4 test flight lifted off from NASA’s Kennedy Space Center. SA-4, an uncrewed test flight of the Saturn I booster, was the final of a series of four tests of the Saturn I first stage. Here, first stages for the SA-4, SA-6 and SA-7 missions are pictured at NASA Marshall Space Flight Center’s Fabrication and Assembly Engineering Division. Marshall designed, developed and managed the production of the Saturn I and the Saturn V rocket that took astronauts to the moon. Today, Marshall is developing NASA’s Space Launch System, the most powerful rocket ever built that will be capable of sending astronauts deeper into space than ever before, including to Mars.
