60 Minutes correspondent Bill Whitaker interviews John Grunsfeld, the NASA astronaut who’s known as the Hubble repairman. Grunsfeld has risked his life three times to repair the space telescope which was supposed to last just 15 years but continues to take snapshots of the universe 27 years later. Grunsfeld tells Whitaker he believes the telescope will last another three to five years.
That said, another telescope, the James Webb Space Telescope, is scheduled to be launched in 2019 and will eventually replace the Hubble Telescope. The Webb telescope is designed to see the first stars and galaxies that were formed in the universe. Grunsfeld believes, “There’s going to be big surprises.” 60 Minutes at 7:30 pm on CBS.
