Just a reminder for those of you in the DC area that there will be a science and engineering festival on the Mall this weekend. Here is the link to more information: http://www.usasciencefestival.org/
I hope to make it down there to see, at the very least, the design mockup of the Planetary Society’s Lightsail spacecraft (link), and the wonderful hosts of Astronomy Cast, Dr. Pamela Gay and Fraser Cain (http://www.astronomycast.com/)
Should be a great weekend to celebrate science and engineering. Join us.
