2011: A Big Year For Space Exploration
Some might be inclined to think 2011 was a pretty bad year for space, what with the U.S. space program shutting down. While the Atlantis marked the last mission in NASA's decades-long space shuttle program, the agency still managed to have other significant launches this year. Crafts visited Mercury, a massive asteroid known as Vesta, and the moon. Another left for Jupiter, and the Voyager 1 spacecraft sailed out of our solar system. Guest host Rebecca Sheir talks to Neil deGrasse Tyson, head of the Hayden Planetarium, about whether all that made 2011 a good year for space exploration.
