For the first time in decades, NASA plans to fly a spaceship during Christmas, giving up the holiday to revive the Hubble Space Telescope. With Hubble out of action until astronauts deliver replacement parts, scientists and NASA managers are rooting for a launch this week of space shuttle Discovery from Kennedy Space Center, Fla., even if it means working over Christmas.

NASA administrator Sean O'Keefe told astronomers meeting in Denver that he was optimistic robots could repair the Hubble Space Telescope, and said the space agency was seeking proposals to do just that. The 14-year-old telescope, whose brilliant pictures from space have earned it more than a cult following, appeared to be doomed just a few months ago because of ongoing problems with the space shuttle. Without repair work, NASA estimates Hubble will stop making observations by 2007 or 2008.

Using the Hubble Space Telescope, astronomers have been able to more precisely measure the mass of a planet circling a distant red dwarf star. Previous estimates of the extrasolar planet ranged from 1.9 to 100 times the size of Jupiter. New measurements show the planet is from 1.89 to 2.4 times the mass of Jupiter. The University of Texas team determined the planet's mass by measuring wobbles it caused in its home star's orbit.

The countdown began for NASA's return visit to the Hubble Space Telescope, amid concerns over a space shuttle fuel cell that may not have been flushed adequately. Discovery is scheduled to blast off early Tuesday on the 10-day mission to add new equipment to the orbiting telescope. The only concern is an electricity- and water-producing fuel cell that might have too much potassium hydroxide residue left inside and could reportedly result in drinking water that is alkaline.

An error by ground controllers triggered an emergency closure of the Hubble Space Telescope's aperture door and sent the observatory into hibernation for nearly 12 hours, NASA officials said. But project officials at the NASA Goddard Space Flight Center in Greenbelt, Md., reported that the $1.5-billion telescope was brought back to normal "quickly and effectively," in part because of the practice the controllers received during the telescope's problem-plagued first week in orbit.

NASA has set Feb. 7 as the new date for launching Europe's Columbus laboratory aboard the space shuttle Atlantis to the International Space Station, officials said Thursday. The rescheduled date depends on whether the flight of a Russian cargo ship, scheduled for the same day, can be changed. The station can support only one docked vehicle at a time. The delay in the launch means Atlantis will likely not be ready for a service mission to the Hubble Space Telescope now scheduled for August.
