New Horizons Principal Investigator for Johns Hopkins University Applied Physics Laboratory
Humankind’s arrival at Pluto is barely two months away. The science and images have already started to flow from New Horizons, according to the mission’s Principal Investigator, Alan Stern. Alan returns to Planetary Radio this week. Curiosity has been busy on Mars, and Emily Lakdawalla has the complete story. Bill Nye is counting down to the May 20 launch of the LightSail solar sail, and Bruce Betts has the absolute truth about the absolute magnitude of our friendly, neighborhood star.
