What can a 45-year-old mission to the Moon tell us about a "meteorite" flying past a skydiver on Earth?
A video of Apollo astronaut David Scott's lecture to the Lunar and Planetary Science Conference. His talk was an absolute treat: funny, educational, engaging, full of joy at his adventure, though at the end, a little angry that we've not sent more humans back. It's well worth 45 minutes of your time.
If there's one thing I've learned after decades of studying the first human voyages to another world, it's that there is always more to discover about Apollo. Case in point: The Apollo 8 Earthrise photo that became one of the iconic images of the 20th century.
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.

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.
