Is water ice present or absent in a crater near the moon's south pole? NASA’s Lunar CRater Observing and Sensing Satellite (LCROSS) mission is seeking a definitive answer. Join Exploratorium staff for a special Webcast featuring live coverage of LCROSS crashing into the moon! Our team will be broadcasting live from the 36" Refractor Telescope at Lick Observatory on Mt. Hamilton, where we’ll watch the impact and investigate how this intentional crash could reveal the existence of water ice.

NPR, or Neighborhood Public Radio is an artists collective and community radio project founded in 2004 by multimedia artists and educators Lee Montgomery, Jon Brumit and Michael Trigilio. Acting as a traveling band of guerilla broadcasters, NPR personnel have hosted thematic broadcasts from San Francisco to Serbia, including a stint at the 2008 Whitney Biennial. What is Neighborhood Public Radio? Imagine a storefront community radio station open to you. You get access to the airwaves regardless of your qualifications or message. We caught up with the founders of the now-decentralized NPR team, in Oakland, Chicago and San Diego to talk about the technical, social and political aspects of broadcasting, and about their tattoos. As a special treat for our listeners we thought it would be fun to ask Lee, Jon and Michael to create a new Audio-Art piece for our Podcast series. The idea was simple. They would each create a composition that was no more than 5 minutes long, and we would layer all three parts together to create a single new work. Visit the link at the bottom to hear the results.

On May 11, 2009, the space shuttle Atlantis was launched from the Kennedy Space Center and docked with the Hubble Space Telescope 360 miles above the earth. During Servicing Mission 4 (SM4), astronauts installed new, cutting-edge scientific instruments and replaced gyroscopes, batteries, and other equipment. After a difficult but very successful upgrade of the telescope, the astronauts released Hubble on May 19. The Exploratorium Webcast team will bring you two live Webcasts (May 20 & May 23) about this arduous mission and the future of the telescope.
