After the Challenger tragedy, Endeavor was built at a cost of one point seven billion dollars. A total of six shuttles were built. The first, Enterprise, was a test model. NASA says the program cost about one hundred fourteen billion dollars over thirty years.
MARIO RITTER: Discovery holds the record for most shuttle flights with thirty-nine. It spent a total of one full year in space. Five shuttles have carried over three hundred fifty astronauts. Sally Ride became the first American woman in space in nineteen eighty-three. Forty-eight women have followed her.
Astronauts representing sixteen countries have flown in space shuttles. The spacecraft helped build the International Space Station, repair the Hubble Space Telescope and launched many satellites and space probes.
So as Atlantis landed for the final time, Astronaut Chris Ferguson simply said "Mission complete, Houston."
CHRIS FERGUSON: "Mission complete, Houston. After serving the world for over thirty years, the space shuttle has earned its place in history, and it has come to a final stop."

Dawn to Vesta
BARBARA KLEIN: Another historic event took place on July fifteenth. The American space agency’s Dawn spacecraft began an extended orbit around the asteroid Vesta.
Marc Rayman is chief engineer of the project.
MARC RAYMAN: “This is the first time a spacecraft has orbited a body in the main asteroid belt between Mars and Jupiter. And so to me one of the things that’s so neat about this mission is we’re visiting one of the last unexplored worlds in the inner Solar System.”
