NASA's newest lunar spaceraft is in good shape as it tackles a month-long trek to the moon after a launching from Virginia last week.

The space agency's Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft has passed its initial checkout phase with flying colors, NASA officials said in an update Wednesday (Sept. 10). The spacecraft launched toward the moon on Friday (Sept. 6) from NASA's Wallops Flight Facility in Wallops Island, Va.

"LADEE is doing fine and its trajectory to the moon is good," NASA officials said in a statement. "The LADEE spacecraft is currently in an elliptical orbit around Earth, about 162,000 miles (260,000 kilometers) in altitude. Mission controllers are now performing an extended checkout phase including guidance, navigation and control characterization, reaction control system tests, and on-board controller tuning."

LADEE's checkup included tracking, acquisition and ranging by all ground stations, they added. Mission controllers at NASA's Ames Research Center in Moffett Field, Calif., also had the probe perform a so-called "momentum dump" manuever, which reduced the spacecraft's spin to a normal level.

Shortly after launch, LADEE's reaction wheels, which are used to stabilize and orient the probe in space, experienced a technical glitch just after the probe's separation from its Minotaur V rocket, but controllers on the ground quickly solved the issue.

LADEE (pronounced "laddie") reached highest point in its current elliptical orbit Tuesday (Sept. 10) at 12:30 p.m. EDT (1630 GMT). The spacecraft is now heading down to its closest Earth approach expected on Sept. 13 at 12:38 p.m. EDT (1638 GMT).

Once LADEE makes its close approach, mission controllers will fire the probe's engines, boosting it into a higher orbit. After two more of these burns catapulting the craft into ever-higher orbits, LADEE will perform its "lunar orbit insertion burn" on Oct. 6, NASA officials said.

"After that we are in lunar orbit," NASA officials wrote. "This LOI burn is one of the most critical phases of the mission, because without it working we do not get into lunar orbit."

The $280 million LADEE mission is tasked with probing the mysteries of lunar dust and the moon's very thin atmosphere from its low orbit around Earth's closest cosmic neighbor. LADEE is expected to perform about 100 days of science including hunting for the answer to a more than 40 year old moon dust mystery.

Apollo astronauts saw a strange glow on the moon's horizon before sunrise. Scientists think that it might have something to do with tiny dust particles lofted high into the moon's atmosphere. LADEE is designed to help them tease out the answer to that lunar riddle.

Not going to vouch other that to say the source is not the typical type to photoshop.  LADEE launches frog:

I saw a story claiming official confirmation...

Frog photobombs NASA launch

Here's something you don't see every day.

A frog was caught on camera during the launch of NASA's Lunar Atmosphere and Dust Environment Explorer spacecraft at the Mid-Atlantic Regional Spaceport in Wallops Island, Va., on Friday.

Jeremy Eggers, a spokesman for the facility, confirmed the veracity of the image of the airborne frog captured by NASA’s remote cameras.

"The photo team confirms the frog is real and was captured in a single frame by one of the remote cameras used to photograph the launch," NASA said. "The condition of the frog, however, is uncertain."

The launch pad, Eggers explained to UniverseToday.com, includes a pool from "the high-volume water deluge system that activates during launches to protect the pad from damage and for noise suppression," which is likely where the frog was before the ignition of the Minotaur 5 rocket.

The spaceport sits on a wildlife refuge that mainly comprises a salt marsh and woodlands and contains habitat for a variety of species, including frogs and migratory birds. NASA says the relationship between its 3,000-acre facility and wildlife on the island is mutually beneficial:

NASA’s launch facilities, roads, and facilities take up a small percentage of the area. The rest of the area remains undeveloped and provides excellent habitat for wildlife. During launches, short term disturbance occurs in the immediate vicinity of the launch pads, but the disturbance is short-lived allowing space launches and a wildlife habitat to coexist.
Of course it's not the first time an animal has interrupted — or been interrupted by — a NASA launch. In 2005, a turkey vulture hit a fuel tank during the launch of STS-114. In 2009, a test launch of the SpaceX Grasshopper startled a herd of cows.
