WALLOPS ISLAND, Va. — NASA began a new trek to the moon Friday night with a dazzling launch from Virginia that sent a spacecraft soaring toward Earth's nearest neighbor to probe the thin lunar atmosphere and, just maybe, solve a 40-year space mystery.

The spacecraft, called the Lunar Atmosphere and Dust Environment Explorer (LADEE for short), launched into space Friday, Sept. 6, at 11:27 p.m. EDT (0327 Sept. 7 GMT) atop a Minotaur V rocket. It marked the first moon shot from Virginia and the maiden voyage of the Minotaur V rocket; space firsts witnessed by thousands of spectators who watched the launch soar from NASA's Wallops Flight Facility here.

"I'm extremely excited," Rick Elphic, LADEE project scientist told SPACE.com before launch. "It's been five years watching this thing develop … It's a solid spacecraft. It tested out completely perfectly, and we've shaken it. We've baked it. We've frozen it. We put it through vacuum testing and it works like a charm… This is where the adventure changes from building the spacecraft to flying it to the moon and doing cool stuff."

"It's the little spacecraft that could," Elphic added. "We're really hoping to do big science with a little spacecraft."

Probing a moon mystery

The $280 million LADEE moon mission is tasked with digging up the dirt on lunar dust and the moon's atmosphere. The three science instruments on the spacecraft will investigate the moon's extremely thin atmosphere and a moon dust mystery dating back to before the Apollo-era.

The Surveyor 7 lander, launched in 1968, recorded a glow from the surface of the moon on the horizon before sunrise. NASA's Apollo astronauts also saw the moon glow and scientists think it could be caused by extremely small particles of dust being lofted high into the moon's atmosphere.

"I love this mission because there are so many great things about it," John Grunsfeld, associate administrator for NASA's science mission directorate, told reporters Thursday (Sept. 5). "We've studied the moon extensively since the Apollo astronauts last left over 40 years ago. When we left the moon, we thought of it as an atmosphere-less ancient surface. Since then … we discovered that the moon, scientifically, is still very much alive. It's still evolving. The LADEE mission is going to give us whole new vistas on our nearest neighbor and I'm very excited about that."

LADEE also plays host to a laser communications demonstration. The new test will allow the spacecraft to use laser technology to send data down to mission controllers on the ground possibly at broadband speeds.

Over the course of about the next 30 days, LADEE will orbit Earth in an elliptical orbit three times before moving into lunar orbit. Once in orbit around the moon, the spacecraft will go through a testing phase when the probe's laser communications demonstration will be tested.

After that, the LADEE spacecraft will perform 100 days of science before running out of fuel and crashing into the surface of Earth's closest cosmic neighbor.

Virginia's moon first

LADEE is NASA's first mission to the moon ever launched from Virginia's Eastern Shore. All but one of the agency's other moon missions launched from pads in Cape Canaveral, Fla. Only the agency's Clementine spacecraft, which launched from California's Vandenberg Air Force Base in 1994, flew from a different spaceport.

LADEE launched from Pad 0B of Virginia's Mid-Atlantic Regional Spaceport located at NASA's Wallops Flight Facility. The night launch may even have been visible to millions more spectators along wide swath of the U.S. East Coast that stretched as far north as Maine and as far south as South Carolina, launch officials said.

Wallops was chosen for this launch partially because of a treaty between the United States and Russia, Butler Hine, LADEE project manager said. The first three stages of the five-stage Minotaur V rocket are reconditioned intercontinental ballistic missile (ICBM) motors restricting the booster's launch location possibilities, Hine said.

"The treaty between the U.S. and Russia only allows a few launch sites for the X-ICBMs," Hine said during a news conference in August. "We can launch out of Kodiak, Alaska, or Vandenberg, Calif., or Wallops Island, Va. Those are the three allowed under the treaty. Kodiak, Alaska, and Vandenberg are better for polar Earth orbits but if we want to get to the moon, we need to launch eastward. Wallops Island is the ideal place to launch this launch vehicle to get us to the moon."

The Minotaur V rocket is built by the Dulles, Va.-based commercial spaceflight company Orbital Sciences Corp. It is one of two Orbital Sciences rockets slated to launch this month. The company also plans to launch a larger Antares rocket on Sept. 17 to fly its first unmanned cargo ship to the International Space Station as a test flight ahead of future delivery runs for NASA.
