The Planetary Society will host an open house Thursday at its new headquarters on South Grand Avenue.
Free public tours will be given from 4 to 7 p.m., and visitors will also be able to meet Bill Nye, the society’s new executive director, and his predecessor Lou Friedman, who helped found the organization 25 years ago.
“… There are two questions that trouble us all from the moment we can think: Where did we come from, and are we alone?” Nye says. “It is the answers to these two questions that is the pursuit of the Planetary Society.”
Learn more about the society’s most ambitious program yet, LightSail-1. Friedman is directing the solar-sail mission, which will use sunlight to propel a small spacecraft — one smaller than a shoebox — in Earth’s orbit. The second and third LightSail missions will reach even farther into space.
“The thing that inspires kids about space exploration — we want to make that inspire the public,” Friedman says.
Tomorrow, Aug. 5, 4-7 p.m., The Planetary Society, 85 S. Grand Ave., Pasadena, (626) 793-5100, planetary.org

What happens when more than 500 artists go back to the drawing board — and the drawing board is a bunch of pavement in Pasadena?
The result is the Pasadena Chalk Festival, an explosion of color and style on the walkways of the Paseo Colorado shopping center. Face-painting and designated areas for kids to try their hand at their own variety of beautiful chalk art make this event a Father’s Day weekend classic.
The Pasadena Chalk Festival this year will also attempt to set a world record for largest display of chalk pavement art.
Saturday and Sunday, June 19-20, 10 a.m.-7 p.m. Free. Paseo Colorado, 280 E. Colorado Blvd. Free. (626) 795-9100, pasadenachalkfestival.com
