BAY ST. LOUIS, Miss. – Engineers at NASA’s John C. Stennis Space Center are wrapping up the first series of tests on core components for the J-2X engine that will power the upper stage of the Ares I crew launch vehicle and the Ares V cargo launch vehicle. The Ares rockets are key elements of NASA’s Constellation Program to return humans to the moon.

Media representatives are invited May 8 to view the ninth- and final – test in this series of the J-2X power pack. Be advised that due to the nature of rocket engine testing, times and dates of tests are subject to change.

In addition to the test, media representatives will receive a briefing on the J-2X project by Stennis Space Center deputy director Gene Goldman and Tom Byrd, J-2X deputy program manager at NASA’s Marshall Space Flight Center in Huntsville, Ala. Media representatives will also tour the Pratt & Whitney Rocketdyne J-2X engine assembly facility at Stennis.

This series of tests is providing valuable information for Pratt & Whitney Rocketdyne engineers as they upgrade pump and gas generator components in development of the new J-2X engine.

Following this test series, Stennis workers will begin maintenance and modifications on the A-1 Test Stand, preparing it for the next round of tests on an upgraded power pack in early 2010.

Members of the media wishing to participate in the tour and J-2X power pack test viewing opportunity should contact the Paul Foerman at 228-688-1880 by noon on May 7. Media members should arrive at Stennis Space Center no later than 11:30 a.m. on May 8 to allow time for credentialing and escort to the engine assembly facility.
