A burst of laser light could let humanity know it is not alone in the universe. Harvard’s Paul Horowitz and Curtis Mead will give us an update on the technological wonder of Optical SETI that watches the entire sky for billionth of a second pulses from the stars. Emily Lakdawalla looks forward to the launch of India’s Mars Orbiter Mission.  Bill Nye has thoughts about a statement by the NASA Administrator, and Bruce Betts doesn’t need a laser to tell us What’s Up in the night sky.
