Day two at the USA Science & Engineering Festival was off to a running start when staff had to dodge race participants (the Army Ten-Miler) to get to the National Mall. Weaving between runners while carrying all our gear woke us up better than any caffeine jolt. Bill Nye gave morning visitors to the booth an impromptu demonstration of how LightSail 1 will deploy in space and later packed in a huge crowd at his presentation at Freedom Plaza. We saw just as many booth visitors on Sunday as on the first day of the festival, which kept LightSail engineers Chris Biddy and Justin Jang busy explaining how our solar sail mission will work. And we owe a big thank you to a wonderful cadre of volunteers, who hung signs, took pictures, carried models and helped us in every way possible.
