The Lunar Atmosphere and Dust Environment Explorer (LADEE) blasts off for the moon on Friday, September 6. We're going to celebrate that launch with another installment of Planetary Radio Live in Pasadena. Join your space enthusiast friends for our live webcast!

The great folks at Southern California Public Radio will once again be our hosts. They will have the webcast on their official event page. We will also put a video player right here on this page (see above) when it becomes available, so you already know where to go for the goods.

We'll begin at 7:30pm Pacific (2:30am UTC). The launch from the Wallops Flight Facility in Virginia is scheduled for 8:27pm Pacific. We'll pass the time till then talking with Society Director of Projects Bruce Betts and UCLA planetary scientist Dr. David Paige. David just received NASA's Exceptional Scientific Achievement Award, largely for his work as principal investigator on the Lunar Reconnaissance Orbiter's Diviner Lunar Radiometer Experiment. Diviner has helped us learn about deposits of water ice on the moon, among other fascinating discoveries. We will also connect via Skype with LADEE Education and Public Outreach Lead Brian Day, before we switch to NASA's coverage of the launch itself.

CAVEAT: Space is hard! It's entirely possible that the launch will be delayed. We'll proceed with the webcast regardless, and I promise a good time for all.
