Problems After Launch of Moon Probe w/ New Laser-Com System

NASA's newest robotic explorer rocketed into space late Friday in an unprecedented moonshot from Virginia that dazzled sky watchers along the East Coast.

It was a change of venue for NASA, which normally launches moon missions from Cape Canaveral, Fla. But it provided a rare light show along the East Coast for those blessed with clear skies.

But the LADEE spacecraft quickly ran into equipment trouble, and while NASA assured everyone early Saturday that the lunar probe was safe and on a perfect track for the moon, officials acknowledged the problem needs to be resolved in the next two to three weeks.

S. Peter Worden, director of NASA's Ames Research Center in California, which developed the spacecraft, told reporters he's confident everything will be working properly in the next few days.

The Lunar Atmosphere and Dust Environment Explorer or LADEE, pronounced "LA'-dee," is taking a roundabout path to the moon, making three huge laps around Earth before getting close enough to pop into lunar orbit.

Unlike the quick three-day Apollo flights to the moon, LADEE will need a full month to reach Earth's closest neighbor. An Air Force Minotaur V rocket, built by Orbital Sciences Corp., provided the ride from NASA's Wallops Flight Facility.

LADEE, which is the size of a small car, is expected to reach the moon on Oct. 6.

Scientists want to learn the composition of the moon's ever-so-delicate atmosphere and how it might change over time. Another puzzle, dating back decades, is whether dust actually levitates from the lunar surface.

The 844-pound spacecraft has three science instruments as well as laser communication test equipment that could revolutionize data relay. NASA hopes to eventually replace its traditional radio systems with laser communications, which would mean faster bandwidth using significantly less power and smaller devices.

"There's no question that as we send humans farther out into the solar system, certainly to Mars," that laser communications will be needed to send high-definition and 3-D video, said NASA's science mission chief, John Grunsfeld, a former astronaut who worked on the Hubble Space Telescope.
