[NASA Press Release - 24.09.2009]
NASA scientists have discovered water molecules in the polar regions of the moon. Instruments aboard three separate spacecraft revealed water molecules in amounts that are greater than predicted, but still relatively small. Hydroxyl, a molecule consisting of one oxygen atom and one hydrogen atom, also was found in the lunar soil. The findings were published in Thursday's edition of the journal Science.

Lunar South Pole - Out of the Shadows

[NASA Press Release - 16.09.2009]
During the LRO Commissioning Phase, the high-resolution Lunar Reconnaissance Orbiter Camera (LROC) captured this 1-m pixel scale (angular resolution) two-image mosaic of the lunar south pole, which is located on the rim of the 19-km diameter Shackleton crater. At meter scales features such as boulders and ridges can be mapped, paving the way for future explorers. Right now we know little of the poles and much is to be learned from the data now being returned from LRO. The rim of Shackleton crater is a prime candidate for future human exploration due to its proximity to permanently shadowed regions and nearby peaks that are illuminated for much of the year. The permanent shadow may harbor cold-trapped volatiles deposited as comets and asteroids impacted the Moon over the past billion years or more. Highly illuminated peaks provide opportunities for solar power during most of the year for future human habitation.

LOIRP and LRO Confirm That Humans Walked on the Moon

[LOIRP Press Release - 20.08.2009]
Yesterday the LRO team released a new image of the Apollo 14 landing site. You can clearly make out the paths that the crew walked as well as the location of the Apollo 14 Antares Lunar Module Descent Stage.

In June 2009 LOIRP issued its own view and analysis of this landing site - as seen by Lunar Orbiter III back in 1967.

Comparing our high resolution image of the site with that taken by LRO clearly shows no feature where Antares' Descent Stage now stands [larger image]. While the resolution of the Lunar Orbiter image (0.8 meters/pixel) would probably not reveal astronaut tracks in great detail, we're rather certain that it would have seen an object the size of Antares' Descent Stage.

[LPI Press Release - 21.07.2009]
The Lunar and Planetary Institute (LPI) is pleased to announce the release of an expanding lunar education new-media portal, MyMoon. MyMoon leverages our new scientific exploration of the Moon and innovative social networking opportunities to engage a fresh new audience in lunar science and exploration - the Net Generation. LPI is collaborating with lunar scientists, educators, artists - and the public - to populate it with science content, diverse media exhibits, events, and opportunities for involvement. Through MyMoon, the public can interact with lunar content that will inform them about NASA's lunar science research and missions, and engage them in future plans for lunar exploration and eventual habitation.

[NASA Press Release - 17.07.2009]
NASA's Lunar Reconnaissance Orbiter, or LRO, has returned its first imagery of the Apollo moon landing sites. The pictures show the Apollo missions' lunar module descent stages sitting on the moon's surface, as long shadows from a low sun angle make the modules' locations evident.

The Lunar Reconnaissance Orbiter Camera, or LROC, was able to image five of the six Apollo sites, with the remaining Apollo 12 site expected to be photographed in the coming weeks.

NASA's LRO Spacecraft Sends First Lunar Images to Earth

[NASA Press Release - 02.07.2009]
NASA's Lunar Reconnaissance Orbiter, or LRO, has transmitted its first images since reaching lunar orbit June 23. The spacecraft has two cameras -- a low resolution Wide Angle Camera and a high resolution Narrow Angle Camera. Collectively known as the Lunar Reconnaissance Orbiter Camera, or LROC, they were activated June 30. The cameras are working well and have returned images of a region a few kilometers east of Hell E crater in the lunar highlands south of Mare Nubium.

NASA Lunar Mission Successfully Enters Moon Orbit

[NASA Press Release - 23.06.2009]
After a four and a half day journey from the Earth, the Lunar Reconnaissance Orbiter, or LRO, has successfully entered orbit around the moon. Engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., confirmed the spacecraft's lunar orbit insertion at 6:27 a.m. EDT Tuesday.

During transit to the moon, engineers performed a mid-course correction to get the spacecraft in the proper position to reach its lunar destination. Since the moon is always moving, the spacecraft shot for a target point ahead of the moon. When close to the moon, LRO used its rocket motor to slow down until the gravity of the moon caught the spacecraft in lunar orbit.

NASA Successfully Launches Lunar Impactor

NASA successfully launched the Lunar Crater Observation and Sensing Satellite, or LCROSS, Thursday on a mission to search for water ice in a permanently shadowed crater at the moon's south pole. The satellite lifted off on an Atlas V rocket from Cape Canaveral Air Force Station, Fla., at 5:32 p.m. EDT, with a companion mission, the Lunar Reconnaissance Orbiter, or LRO.

LRO safely separated from LCROSS 45 minutes later. LCROSS then was powered-up, and the mission operations team at NASA's Ames Research Center at Moffett Field, Calif., performed system checks that confirmed the spacecraft is fully functional.

NASA Returning to the Moon with First Lunar Launch in a Decade

[NASA Press Release - 19.06.2009]
NASA's Lunar Reconnaissance Orbiter launched at 5:32 p.m. EDT Thursday aboard an Atlas V rocket from Cape Canaveral Air Force Station in Florida. The satellite will relay more information about the lunar environment than any other previous mission to the moon.

The orbiter, known as LRO, separated from the Atlas V rocket carrying it and a companion mission, the Lunar Crater Observation and Sensing Satellite, or LCROSS, and immediately began powering up the components necessary to control the spacecraft. The flight operations team established communication with LRO and commanded the successful deployment of the solar array at 7:40 p.m. The operations team continues to check out the spacecraft subsystems and prepare for the first mid-course correction maneuver. NASA scientists expect to establish communications with LCROSS about four hours after launch, at approximately 9:30 p.m.

[NASA Press Release - 17.06.2009]
NASA's Lunar Reconnaissance Orbiter, or LRO, and the Lunar Crater Observation and Sensing Satellite, or LCROSS, rolled aboard their Atlas V rocket to the launch pad at Cape Canaveral Air Force Station in Florida Wednesday morning in preparation for launch on Thursday. The spacecraft left its processing facility at 10:02 EDT and arrived at the pad about 35 minutes later.
