LADEE Launches From NASA Wallops
A Minotaur V rocket carrying NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) lifts off from at NASA's Wallops Flight Facility in Virginia on Friday, Sept. 6, 2013. LADEE is a robotic mission designed to orbit the moon where and provide unprecedented information about the environment around the moon and give scientists a better understanding of other planetary bodies in our solar system and beyond.

LADEE Spin Test
During preparations for NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) observatory launch on Sept. 6, 2013, the spacecraft went through final preparations and close-outs, which included checking alignment after its cross-country shipment, checking the propulsion system for leaks, inspecting and repairing solar panels, and final electrical tests. After these activities were completed, more challenging portions of the launch preparations began: spin testing and fueling.
To make sure that the spacecraft is perfectly balanced for flight, engineers mounted it onto a spin table and rotate it at high speeds, approximately one revolution per second. The team measured any offsets during the spinning, and then added small weights to the spacecraft to balance it. Once the spacecraft was balanced dry, the team loaded the propulsion tanks with fuel, oxidizer, and pressurant. The spin testing was performed again "wet," or with fuel, in order to see if the balance changed with the full fuel tanks.
Engineers from NASA's Ames Research Center in Moffett Field, Calif., have now successfully completed launch preparation activities for LADEE, which has been encapsulated into the nose-cone of the Minotaur V rocket at NASA's Wallops Flight Facility in Virginia. LADEE is ready to launch when the window opens on Friday.

LADEE Ready for Launch
In an attempt to answer prevailing questions about our moon, NASA is making final preparations to launch a probe at 11:27 p.m. EDT Friday, Sept. 6, from NASA's Wallops Flight Facility on Wallops Island, Va.
The small car-sized Lunar Atmosphere and Dust Environment Explorer (LADEE) is a robotic mission that will orbit the moon to gather detailed information about the structure and composition of the thin lunar atmosphere and determine whether dust is being lofted into the lunar sky. A thorough understanding of these characteristics of our nearest celestial neighbor will help researchers understand other bodies in the solar system, such as large asteroids, Mercury, and the moons of outer planets.

On Friday, Sept. 6, NASA is scheduled to launch a small satellite mission, called the Lunar Atmosphere and Dust Environment Explorer (LADEE), which will orbit the moon to gather detailed information about its atmosphere and the role of dust in the lunar sky.
LADEE is the first spacecraft designed, developed, built, integrated and tested at NASA's Ames Research Center in Moffett Field, Calif. Using a Modular Common Spacecraft Bus architecture, also developed by Ames, LADEE will demonstrate how to build a first class spacecraft at reduced cost. The LADEE spacecraft makes use of general purpose spacecraft modules that allow for a plug-and-play approach to manufacturing and assembly. This approach along with commercial off-the-shelf products allows mission designers to develop, assemble and test multiple spacecraft modules at the same time – essentially giving them the versatility to get the biggest bang for NASA's buck.
“LADEE’s common bus is an innovative concept that brings NASA a step closer to multi-use designs and assembly line production, while moving away from custom design,” said Ames Director S. Pete Worden. "This mission will put the common bus design to the test. This same common bus can be used on future missions to explore other destinations, including voyages to orbit and land on the moon, low-Earth orbit, and near-Earth objects."
The space agency has adopted a “more with less” approach to robotic missions. It also is about using NASA’s small satellite missions to test cutting-edge space technologies for rapid development. These technology demonstrations allow NASA the opportunities to test in space emerging science and engineering technologies, and economical commercial off-the-shelf technologies on a smaller scale. These demonstrations also help researchers better understand how hardware will survive the harsh radiation, temperature and vacuum conditions encountered in space. All while being faster, more efficient and less expensive than traditional missions.
Findings could reap untold benefits for science and industry here on Earth. Rapid technology developments will allow future NASA missions to pursue bolder and more sophisticated science, enable safe and rewarding human missions beyond low-Earth orbit and enable entirely new approaches to U.S. space operations.
“NASA is looking for affordable ways to launch often and inexpensively,” said David Korsmeyer, Director of Engineering at NASA Ames. “We can use off-the-shelf components because customized components are expensive to continually develop and improve. If these systems work successfully, NASA will be looking for other commercial technologies to use for space exploration.”
Instead of building increasingly large and complex exploratory missions, these low-cost accelerated missions could open the door for creativity, clever problem solving, and inspired missions with simple goals. Mission planners expect the next decade could see amazing developments as NASA continues to fund missions using this innovative concept.
“Simplicity was not a necessary aspect of this mission, but is clearly a driver for successful missions,” said Butler Hine, LADEE project manager at Ames. “The important thing is to maximize the success per dollar.”
NASA's Science Mission Directorate in Washington funds the LADEE mission. In addition to designing the spacecraft, Ames manages the overall mission, operates the spacecraft, and hosts the project scientist. Goddard manages the science instruments and technology demonstration payload, the science operations center and provides overall mission support. Wallops is responsible for launch vehicle integration, launch services and operations. NASA's Marshall Space Flight Center in Huntsville, Ala., manages LADEE within the Lunar Quest Program Office.
