From Kepler to Webb: The History of the Telescope

Hank regales us with the history of the telescope, and then introduces us to some folks from the team who are working on the newest telescope in the chronology - the James Webb Space Telescope, an infrared telescope due to launch in 2018. Thanks to the team at Northrop Grumman for allowing us the privilege of touring their facility, and to the scientists at NASA Goddard Space Flight Center for their help with this video.
