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.

NASA's efforts to get the ailing Hubble Space Telescope working again have hit a snag, and engineers are trying to figure out their next step. Officials had hoped to have the 18-year-old observatory back in business Friday, after it stopped sending pictures three weeks ago. But a pair of problems cropped up Thursday. First, a low-voltage power supply problem prevented one of the Hubble's cameras from rebooting properly, and then computer trouble struck, and all efforts ceased.

The Hubble Space Telescope has looked 13 billion years back to the universe's infancy, when stars finally began to shine, astronomers reported this week. The signal of the end of the cosmic dark ages is the detection of about 30 faint red objects by the orbiting telescope, according to Haojing Yan of Arizona State University.
