Today marks the 40th anniversary of the last human footsteps on the Moon. In my latest video I look back at Apollo 17 and explain why I believe the Moon is the solar system's "jewel in the crown," beckoning us to return.
Today I stumbled upon the Lunar and Planetary Institute's Lunar Sample Atlas, and was reminded of how much I love petrographic thin sections. They can make unassuming, cruddy looking rocks beautiful.
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.

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.
