05/01/2017 Vibration testing of James Webb telescope and instruments set to resume in January.

The vibration testing of the James Webb telescope and instrument assembly (called OTIS) was put on hold in December 2016 after an unexpected response to the vibrations was detected. The investigation of the event is still on-going but the plan is now to resume testing in January. More information can be found on NASA's JWST web site at the following link:

07/06/2016 JWST's payload module successfully installed

On the 24th of May 2016, JWST's payload module, called ISIM, was installed on the back of the telescope. In preparation for this installation, the telescope was oriented face down in the large clean room at the Goddard Space Flight Center. During the installation, NASA photograph Chris Gunn captured a spectacular view of ISIM hanging above the telescope.
