If you go to a conference about lunar geology, sooner or later you'll hear the term "KREEP" bandied about. (And almost as soon as KREEP is mentioned, a bad pun will be made. It's inevitable.) Context will tell you it has something to do with a special kind of lunar rock, but that'll only get you so far. What is KREEP, and why is it important on the Moon?

In a paper recently published in the Journal of Geophysical Research, Georgiana Kramer and several coauthors performed a careful comparison of two data sets that seem like they're measuring the same things, so you'd think that the measurements they took would match between the two instruments. But they don't quite match.
Back to Apollo? Or Time for a Restart?

To see the bigger picture, it can help to step back a bit from your current position. Sometimes you need to consider the past to inform your vision for the future.

The LROC team posted today a new image of the Apollo 17 landing site, captured after Lunar Reconnaissance Orbiter had gotten in to its 50-kilometer mapping orbit, so this is much more detailed than the previous view.

As a reminder that we've been crashing stuff into the Moon for decades, the Lunar Reconnaissance Orbiter Camera (LROC) team released today a photo of the crater made by the spent upper stage of the Saturn rocket that lofted the Apollo 14 mission to the Moon.

For over four decades, the lunar science community has absorbed the information from the Apollo missions. Although many important questions were answered, many important new questions are waiting to be tackled -- which is the very essence of science and exploration.

One primary goal of the LRO mission is to acquire the amazing bounty of scientific data necessary to enable future human lunar exploration and utilization. But why should we even bother going back?

It is a day where when all humans should take time to celebrate the momentous achievement that put two brave explorers on the face of another world. As Sir Arthur Clarke once famously said, the Apollo voyages will likely be the only events for which the 20th century will be remembered in the future, when humans live throughout the Solar System and beyond.

Grab your bell bottoms and Tang, and travel back to 1969 when Apollo 11's journey to the Moon captivated the world, and Neil Armstrong's and Buzz Aldrin's boot prints in the lunar dust transformed us into a multi-world species.

This summer, the Smithsonian Institution's National Air and Space Museum in Washington, D.C. will commemorate that extraordinary moment in history with a very special Apollo 11 celebration, featuring the mission's original crew members along with former Johnson Space Center Director Chris Kraft.

I spent a large portion of the day at the Lunar and Planetary Institute's library and presented my own poster during the poster sessions, so my coverage of Thursday's sessions is limited.
