Webb Lifted on the Hardpoint Offloader Support System (HOSS)
Released on May 31, 2017
The James Webb Space Telescope is preparing for it's final large test in Chamber A. The Apollo-era vacuum chamber simulates the vacuum and temperatures of space.
In this series of shots Webb is being lifted onto the Hardpoint Offloader Support System, or HOSS, for short. The HOSS is a rail system that will support the Telescope as it is pushed into the Chamber.
With help from Goddard Space Flight Center, Johnson Space Center in Houston, TX built a new cleanroon around Chamber A in 2013 in preparation for Webb's testing.
