Show 13: Good Vibrations
November 30, 2011
It's time to shake things up. Webb's mirrors undergo vibration testing to simulate the experience of being launched into space. These tests ensure that the mirror segments will survive their trip into orbit without damage.
Show 12: On the Wings of Apollo
September 23, 2011
At Johnson Space Center in Houston, Texas, a cavernous chamber is being modified for use in testing the Webb Telescope. Environmental testing is part of the myriad of tests Webb must endure to be deemed space-worthy.
Show 11: Great Plane
May 6, 2011
Webb's backplane will hold its 18 hexagonal mirror segments in place, allowing them to function as one. Engineers take us through the backplane design process.
Show 10: Wax On, Wax Off
March 9, 2011
Webb's mirrors must be precisely shaped to best capture light and direct it to the telescope's detectors. Watch as the mirrors are ground and polished to the perfect configuration.
Show 9: Not So Heavy Metal
January 13, 2011
Webb's perfectly polished, highly reflective mirrors start their life as a pile of rubble, mined from a desert in Utah. Join "Behind the Webb" as we explore a beryllium mining operation.
Show 8: Stretching Webb's Wings
November 17, 2010
Webb's protective sunshield will be folded up inside the rocket that carries it into orbit. Engineers explain the process of unfurling the sunshield from a million miles away.
Show 7: Got Your Back
October 8, 2010
Webb's mirror, made of 18 individual segments, will be folded up inside the rocket that carries the telescope into orbit. Engineers are constructing the frame at the back of the mirror that will adjust Webb's segments to achieve a single perfect focus.
Show 6: Troubleshooting Webb
August 18, 2010
At Northrop Grumman, engineers are testing the systems that will control Webb from the ground. Because Webb will orbit 940,000 miles (1.5 million km) from Earth, itŐs vital to ensure perfect long-distance control.
