NASA’s J-2X Upper Stage Rocket Engine Ready for Testing
By Jennifer Stanfield
In This Week's Star (Click to Expand)|
The J-2X engine, the new rocket engine that could power the upper stage of NASA's future heavy lift launch vehicle, is fully assembled and ready for testing. The J-2X, designed and built by Pratt & Whitney Rocketdyne of Canoga Park, Calif., for NASA’s Marshall Space Flight Center, is installed in the A-2 Test Stand at NASA’s Stennis Space Center. It is scheduled to undergo a series of 10 test firings beginning in mid-June and lasting several months. Collected data will verify the engine functions as designed.

The J-2X builds on heritage designs but relies on nearly a half-century of NASA spaceflight experience and technological advances. (NASA)
"An upper stage engine is essential to making space exploration outside low-Earth orbit a reality," said Mike Kynard, manager of the J-2X upper stage engine project at Marshall. "The J-2X goes beyond the limits of its historic predecessor and achieves higher thrust, performance and reliability than the J2. We are thrilled to have the engine in the test stand to validate our assumptions about engine performance and reliability."
The test stand transition work from the space shuttle main engine project to the J-2X test project included structural, electrical and plumbing modifications to accommodate the different geometry of the J-2X engine, and included the installation of a new J-2X engine start system. Also replaced on the stand were liquid oxygen and liquid hydrogen transfer lines and piping that dated back to the 1960s. Control systems also were upgraded on the stand.
Fueled by liquid hydrogen and liquid oxygen, the J-2X engine will generate 294,000 pounds of thrust in its primary operating mode to propel a spacecraft into low-Earth orbit. By changing the mixture ratio of liquid oxygen to liquid hydrogen, the J-2X can operate in a secondary mode of 242,000 pounds of thrust required to power a spacecraft from low-Earth orbit to the moon, an asteroid, or other celestial destinations. The J-2X can start and restart in space to support a variety of mission requirements.
"We are excited to have a new engine in the A-2 Test Stand," said Gary Benton, manager of the J-2X engine testing project at Stennis. "Installation of the J-2X engine marks the beginning of the third major rocket engine test project on this historic stand. The A-2 Test Stand originally was used to test Saturn V rocket stages for NASA’s Apollo Program. In the mid-1970s, the stand was modified from Apollo Program parameters to allow testing of space shuttle main engines. The test stand was once again modified to prepare for J-2X engine testing."

STS-135 Mission Targeted to Launch July 8
Shuttle Atlantis to Deliver Supplies, Spare Parts to Space Station
NASA is targeting July 8 for the launch of space shuttle Atlantis on a 12-day mission. Aboard will be the Raffaello multipurpose logistics module, filled with supplies, equipment and spare parts for the International Space Station. The module, managed by the Marshall Space Flight Center, is approximately 21 feet long, 15 feet in diameter, weighs 4.5 tons and can deliver up to 10 tons of cargo to the space station. The mission also will fly a system to investigate the potential for robotically refueling existing spacecraft and return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. Launch is scheduled for 10:26 a.m. CDT.

Utah State Wins Student Launch Rocketry Challenge
By Angela Storey
NASA has named student rocketeers from Utah State University in Logan the champions in the 10th annual NASA Student Launch Projects rocketry challenge, which seeks to inspire young people to pursue rewarding careers in science, technology, engineering and mathematics.

The win for Utah State University is its third in the past four years. Competitors from the Massachusetts Institute of Technology in Cambridge and Vanderbilt University in Nashville, Tenn., won second and third place, respectively. The "Rookie of the Year" award also went to competition newcomer Massachusetts Institute of Technology.
A record 27 student teams from colleges and universities across the nation participated in this year's challenge. Each year, student teams vie to see whose rocket can come closest to the 1-mile altitude goal and safely return its onboard science or engineering payload -- which they also must design and build as part of the challenge. The student teams also maintain project websites and create local educational campaigns to excite younger students about technical fields of learning -- potentially cultivating still more future scientists, engineers and national leaders.
The Marshall Space Flight Center organizes the rocketry competition each year at Bragg Farms in Toney, Ala., which has hosted the launch challenge since 2008. It is sponsored by ATK Aerospace Systems of Salt Lake City, Utah.

(NASA/David Higginbotham)
During the April launch event that concluded the 2010-11 competition, NASA and ATK presented a variety of preliminary awards. In addition to its top trophies, Vanderbilt won "Best Payload Design" -- for its novel, liquid-nitrogen injection system, simulating the working behavior of an airplane engine at cruising altitude -- and Massachusetts Institute of Technology earned the "Project Review" award for the best written reports, flight readiness reviews and formal presentations.
Top-prize winner Utah State also was honored for "Best Vehicle Design," an award the school last received in 2009, the last year it also won the entire competition.

NASA held the first student launch event in 2000-01. In response to its growing popularity, NASA expanded it in 2006, creating one division for colleges and universities and another, non-competitive division for middle schools and high schools. The event expanded this year with a new pilot demonstration of a second-level university challenge, held May 21 at NASA's Wallops Flight Facility on Wallops Island, Va.
The Marshall Center's Academic Affairs Office, part of the Office of Human Capital, manages the rocketry challenge. The project is sponsored by NASA's Exploration Systems Mission Directorate, Space Operations Mission Directorate, Science Mission Directorate and the Education Flight Projects Office in NASA’s Office of Education, all at NASA Headquarters in Washington. ATK provided corporate sponsorship. The National Association of Rocketry provided technical review and launch support. Watch archived video of the entire launch event at:
