The Hubble Space Telescope (HST) is one of NASA's greatest achievements — for more than 20 years, the telescope has orbited the earth and provided us with some of the most stunning space images you could hope to see. At the 221st meeting of American Astronomical Society, NASA reiterated its plans to keep Hubble operating as long as it can. "Hubble will continue to operate as long as its systems are running well," said NASA's Paul Hertz. He also noted that while NASA hoped Hubble's fifth and final overhaul in 2009 would let it run through at least 2015, the agency now believes it should be functional for at least the next six years or so. And despite the planned launch of the James Webb Space Telescope in 2018, NASA hopes both telescopes will operate in harmony for at least a little while. "It may be great if we get at least one year of overlap between JWST and Hubble," Hertz said.
