Next-generation rocket engine
On May 8, 2008, NASA engineers wrapped up their first series of tests on the agency's next generation of rocket engine, the J-2X. The J-2X will power the upper stages of the Ares I and Ares V rockets, designed to carry astronauts and cargo to the International Space Station, the moon, and even Mars.
Part of the J-2X development process has been to test older J-2 engine components, which have been used in various missions dating back to the Apollo program in the 1960s. Data collected from those tests will be used to refine the J-2X designs.
NASA has more information about the Ares launch vehicles here.
