EDWARDS AIR FORCE BASE, Calif. — Space shuttle Atlantis and its seven astronauts returned safely to Earth on Sunday, detouring from stormy Florida to sun-splashed California to end a 13-day mission that repaired and enhanced the Hubble Space Telescope.
"Now and only now can we declare this mission a total success — the astronauts are safely on the ground," NASA sciences chief Ed Weiler said.
Atlantis' crew had waited since Friday for the go-ahead to land as Mission Control hoped to avoid the time and expense — about $1.8 million — of diverting to California's Edwards Air Force Base.
The Florida weather refused to yield and Mission Control finally directed shuttle commander Scott Altman to head to California. The shuttle's twin sonic booms rocked the Mojave Desert as it swooped out of a dazzling morning sky.
It was the 53rd shuttle landing at Edwards; the last one was in November.
The crew set foot on the ground about two hours after touchdown, receiving greetings from ground personnel before they began the customary walk-around to inspect the exterior of their spacecraft.
NASA officials said it will take about a week to prepare Atlantis for its ferry flight back to Kennedy Space Center atop a NASA Boeing 747.
During five space walks, the astronauts gave the 19-year-old Hubble new science instruments, pointing devices and batteries, and fixed broken instruments. The astronauts overcame stuck bolts and other difficulties.
The work will add years to the life of the telescope and its study of the universe.
Initial checkouts of the repaired Hubble were going well, Weiler said. He noted that the telescope had yet to see any starlight but said he expected it to gather data by August.
Much was made of Atlantis' departure from Hubble as the last time it will be touched by humans, and Weiler acknowledged that was an "emotional moment." But he wanted nothing to do with sad thoughts.
"Geez!" he exclaimed. "We just repaired the Hubble Space Telescope. We got a new telescope, four new instruments, two of them dead now alive. We've got another five, six, seven, eight years with the new telescope. These are truly the best of times, not the worst of times."
NASA eventually expects to steer Hubble into the Pacific sometime in the early 2020s using a robotic vehicle, though it's possible that might be done with a manned vehicle, NASA's new Orion.
