The James Webb Space Telescope's science instruments were installed last week in a surgically precise operation. Read more: http://go.nasa.gov/1Wg8FNN #JWST

With surgical precision, two dozen engineers and technicians successfully installed the package of science instruments of the James Webb Space Telescope into the telescope structure.

This time-lapse video shows the Webbcam view of the exciting lifting and turning of the James Webb Space Telescope. It was being oriented for the installation of the science instruments. In the video you can see the excited crowd of NASA Goddard employees watching the telescope move via the window at far right. #throwbackthursday

This video is also available on YouTube: https://youtu.be/APE_MiJ8GRY

Here is another view from inside the cleanroom: https://youtu.be/PhGfgREoBj4

Here's a gorgeous time-lapse of the James Webb Space Telescope's golden mirror being raised to the vertical, and giving NASA Goddard​ an unprecedented look. This was captured from inside the cleanroom: https://youtu.be/PhGfgREoBj4

More info: In this rare timelapse video see inside the world's largest clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland as the James Webb Space Telescope team lifts and turns the telescope for the first time. With glimmering gold surfaces, the large primary and rounded secondary mirror on this telescope are specially designed to reflect infrared light from some of the first stars ever born. The team will now begin to prepare to install the telescope's science instruments to the back of the mirrors. Webb is an international project led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency. For more information, visit: www.jwst.nasa.gov or www.nasa.gov/webb

Engineers take a close look at #JWST's primary mirror at NASA Goddard in this new image shot by our photographer Chris Gunn.

The secondary mirror is the round mirror located at the end of the long booms, which are folded into their launch configuration. The team is prepping to rotate the telescope so the instrument module can be installed behind the primary mirror.

Here's a view from overhead of the golden James Webb Space Telescope, with its secondary mirror booms stowed. This is the position the secondary mirror will be in during launch. Preparations are being done to rotate the telescope in order to install the flight instrument module behind the primary mirror.

JWST's mirrors are covered in a microscopically thin layer of gold, which optimizes them for reflecting infrared light, which is the primary wavelength of light this telescope will observe.

We made a montage of the entire series of selfies taken by Dr. John Mather (JWST project scientist and Nobel Laureate) while the James Webb Space Telescope rotated past the NASA Goddard crowd watching in the cleanroom observation window.

We've made the individual shots available for download - we thought the folks in the pictures might like to have them. Go here for the full set: https://www.flickr.com/photos/nasa_goddard/sets/72157668657475865

All about the next generation James Webb Space Telescope!
Introduction

The James Webb Space Telescope is the successor to Hubble. It is an infrared telescope with a 6.5m mirror and a sunshade the size of a regulation tennis court! It will launch in 2018.
