Orbiter Vehicles

America's fleet of Space Shuttle orbiters are named after pioneering sea vessels which established new frontiers in research and exploration. NASA delved through the history books to find ships which achieved historical significance through discoveries about the world's oceans or the Earth itself. Another important criterion in the selection process was consideration for the international nature of the Space Shuttle program. The name of NASA's newest orbiter, Endeavour was selected from names submitted by school children around the world.
