LOS ANGELES (AP) - A NASAtelescope is operating normally again after a mishap nearly ended its missiontwo years ago, scientists said Thursday.
The orbiting telescopecalled FUSE - Far Ultraviolet Spectroscopic Explorer - returned to fullstrength last month after engineers fixed the problem with its onboard softwarecontrol system, said William Blair of the Johns Hopkins University, who is partof the project.
"The old satellite stillhas some spunk,'' Blair said in a statement.
Launched in 1999, FUSEviews objects by splitting light into thousands of spectra, or bands. So far,the telescope has detected a circle of hotgas surrounding the Milky Way, and found evidence of molecularhydrogen in Mars' atmosphere.
In 2001, two of thetelescope's four reaction wheels, which control its direction, failed, butresumed again two months later. But in 2004, a third reaction wheel stoppedspinning.
