NASA to Begin Testing Engine That Will Power Ares Rockets

An original J-2 engine undergoes processing at NASA's Marshall Space Flight Center in Huntsville, Ala., in 1965. The Apollo-era engine, used to power the second stage of the Saturn V rockets to the moon, is being studied anew by NASA rocket scientists building the engines that will power the next generation of launch vehicles, the Ares I and Ares V, and carry human explorers to the moon. The Saturn V, like key hardware and components of the Ares launch vehicles, was designed, developed and tested by Marshall Center engineers. (NASA/MSFC)
