There once was an age of exploration, when humans set out to see for themselves what was over the next ridge. Those days seem to be gone -- when was the last time you saw a Lewis and/or Clark feted in the media? Oh, the spirit of adventure and curiosity are still present in humanity, we've just broadened our horizons by a magnitude. These days, we launch robots into the vastness of space and have them report back to us from their destination, whether that's Mars (hello, Curiosity rover) or the edge of our solar system (so long, Voyager 1; keep in touch). Tonight at the Jefferson National Expansion Memorial (11 North Fourth Street; 314-655-1750 or www.nps.gov/jeff) Washington University research assistant Michael Zanetti discusses the state of robot explorers in a presentation entitled Solar System Explorers. The St. Louis Astronomical Society will have telescopes set up outside for stargazing, weather permitting. The fun lasts from 8 to 10:30 p.m. and admission is free.
