This week in 1969, the Apollo 10 crew splashed down in the Pacific Ocean following a successful eight-day mission to rehearse the lunar landing. Here, Saturn V first stage is prepared for final assembly in the high bay area of the Vehicle Assembly Building at NASA’s Kennedy Space Center. NASA’s Marshall Space Flight Center designed, developed and managed the production of 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.
