Tiny satellites, also known as CubeSats, are pictured after being deployed into Earth orbit from a small satellite orbital deployer on the outside of the International Space Station's Kibo laboratory module. The CubeSats were delivered aboard the Northrop Grumman Cygnus space freighter and will serve a variety of educational and research purposes for public and private organizations around the world.
