The launch is scheduled for 11:30 p.m. Friday night September 6. NASA held a news briefing Thursday afternoon on NASA TV and online.
The LADEE will orbit the moon and try to determine if any dust is escaping into the lunar atmosphere.
"The moon's tenuous atmosphere may be more common in the solar system than we thought," said John Grunsfeld, NASA's associate administrator for science in Washington. "Further understanding of the moon's atmosphere many also help us better understand our diverse solar system and its evolution."
The launch will be the very first from Wallops to go beyond the earths atmosphere.
