Kepler is a space observatory craft launched in 2009 to discover planets orbiting stars outside the Solar System, and monitors brightness of stars.
Two of Kepler's reaction wheels, gyroscope-like devices used to orient the spacecraft, have failed, and scientists are searching for other ways to utilize the craft, the statement said.
On Aug. 2 NASA called for scientific papers suggesting other missions for the telescope, and after a review expected to finish at the end of the year, an assessment of Kepler's potential will be made.
