This week in 1961, the first Saturn I rocket, SA-1, arrived at NASA’s Kennedy Space Center. The SA-1 mission was used to demonstrate the validity of the clustered engine concept as well as test the aerodynamic and structural design of the Saturn I booster. Here, the S-1 stage for the SA-1 mission is being installed on the launch pad for its Oct. 27, 1961, launch. 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.
