08 May 2017 JWST's payload module (OTIS) arrives at NASA's Johnson Space Center.
After an extensive and very succesful period of integration and testing at NASA's Goddard Space Flight Center, in Greenbelt, Maryland, JWST's payload module (the telescope and its instruments) called OTIS has been shipped to the Johnson Space Center where it will have its final thermal vacuum testing. Detailed information can be found in the following press release issued by NASA:
30 January 2017 Vibration testing on the James Webb Space Telescope successfully resumed last week.
The vibration testing on the telescope and instruments of JWST successfully resumed last week at NASA's Goddard Space Flight Center, in Greenbelt, Maryland. Detailed information can be found in the following press release issued by NASA:
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.
