CAPE CANAVERAL, Fla. – NASA astronaut candidates Jessica Meir, Tyler Nick Hague and Nicole Mann listen to a discussion about firing rooms inside the Launch Control Center at Kennedy Space Center in Florida during a daylong set of briefings and tours of different facilities at NASA's primary launch center. The astronaut class of 2013 was selected by NASA after an extensive year-and-a-half search. The new group will help the agency push the boundaries of exploration and travel to new destinations in the solar system.
