New Work Assignments for Moon Mission
NASA's Glenn Research Center and nine other NASA field centers received good news yesterday. Agency managers announced new work assignments for the Constellation Program, which is developing a fleet of spacecraft to carry astronauts to the moon by 2020.
The new work assignments will allow the field centers to begin planning and preparing for development of the lunar lander, lunar operations and Ares V heavy-lift rocket that will carry astronauts from Earth orbit to the moon.

Glenn's new roles include leading the development of the Ares V rocket's power system, thrust vector control and payload shroud. The thrust vector control system will steer the rocket, and the payload shroud will protect the lunar lander as it reaches Earth's orbit aboard Ares V.
"The shroud is about 10 meters in diameter," said Robert Moorehead, Glenn's director of space flight systems. "It will be the largest payload shroud ever developed."
The center also will lead the development of the lunar lander's ascent stage propulsion system, which "gets man back from the moon to Earth," said Moorehead. As lead for surface systems power generation and energy storage, the center will explore options including solar arrays, batteries and fuel cells to power a habitat, rovers and other equipment for the lunar base.
Glenn's Plum Brook Station facility near Sandusky will test the Ares V Earth departure stage and the lunar lander in a simulated space environment.

Glenn has extensive experience in designing space power and propulsion systems as well as testing space hardware. "These assignments are consistent with our competencies and capabilities," said Center Director Dr. Woodrow Whitlow Jr. "They recognize our accomplishments so far."
Development of NASA's new fleet of spacecraft is well underway. In fact, NASA Glenn has already begun the work on the Ares I crew launch vehicle and the Orion crew module that was assigned in June 2006
