Telescope that found 5,000 planets 'put to sleep' over low fuel
Expected to run out of fuel in a few months, NASA has placed its Kepler Space Telescope in a no-fuel-use safe mode to download its latest scientific data. Launched in 2009, Kepler has discovered over 5,000 candidates and confirmed exoplanets. The Earth-orbiting observatory will point its antenna towards the planet for data transfer and will begin operations in August, said NASA.
