NASA engineers got the thumbs up on Monday to start planning a robotic mission to rescue the Hubble Space Telescope NASA chief Sean O'Keefe told engineers at Goddard Space Flight Center in Maryland to plan a way to repair the instrument and to install two new instruments
"Everybody says, 'We want to save the Hubble' ? well, let's go save the Hubble," O'Keefe said.
The agency chief said the mission, which wouldn't happen for at least three years, would cost roughly $1 billion to $1.6 billion. A plan will take nine months to a year to formulate, he said.
