Yuri's Night "space raves" around the world on April 12

Here's the math: 49 parties, 18 countries, 6 continents, one planet. The event known as "Yuri’s Night: The World Space Party" celebrates 45 years of human space exploration with tech ravers in concurrent parties all over the world. A trio of cool young astro-geeks (Loretta Hidalgo, George Whitesides, and Trish Garner) are behind it all, and I'll be covering the LA edition on April 12 for NPR's "Day to Day." Snip from the website:
A live web cast will join the various Yuri’s Night parties around the globe that are happening at concurrent times. First observed in 2000, Yuri’s Night occurs annually on April 12, marking the anniversaries of Russian Cosmonaut Yuri Gagarin’s first spaceflight in 1961 and the first space shuttle mission 20 years later. Each year, a series of space-themed parties, dinners and educational events are held around the world to mark these historic achievements. Organized by the non-profit Space Generation Foundation, Yuri’s Night combines popular music, science, and art to introduce teens and young adults to the thrill of space.
