Webb Flight Structure Delivered

The flight structure for the Webb integrated science instrument module has been delivered to NASA. In the next two years, the science instrument teams will use this structure for ambient and cryogenic testing of the flight instruments, which are now under construction. (Initial testing will use engineering models of the instruments, which will soon be delivered to NASA.) The composite structure was created by Alliant Techsystems (ATK) at its Magna, Utah facility where the Webb Telescope’s backplane is also being assembled. These two structures must hold the science instruments and mirror segments during the rigors of launch and retain their shape and strength as they cool from room temperature to ~40K.
