The Hubble Space Telescope appears better than new as NASA puts the 19-year-old observatory through a battery of tests after its final facelift by an astronaut repair crew.
Ed Weiler, NASA's science missions chief, said Hubble is in the midst of meticulous systems and calibration checks following the successful upgrades and repairs by Atlantis shuttle astronauts.
The calibrations and electronics tests should run their course by the end of summer, with a new and improved Hubble once more ready for science observations in late August, Weiler said.
Commanded by veteran spaceflyer Scott Altman, the Atlantis astronauts launched toward Hubble on May 11 and performed a five-spacewalk marathon that left the iconic space observatory more powerful than ever before.
