However, NASA is looking into just how feasible it might be to perform emergency servicing operations on the Webb telescope if such a need were to arise and if such a servicing capability were to become available sometime in the future.
"We are currently studying the possibility of adding a lightweight grapple fixture to JWST," said John Decker, Deputy Associate Director of the JWST Project at NASA Goddard Space Flight Center, Greenbelt, Md. "A grapple fixture is a kind of a grab bar that would afford a means for a future manned or robotic servicing capability to safely attach to the telescope in space."
Once the engineers who are assessing the feasibility of adding the grapple feature have concluded the study, they will present the results to NASA Headquarters. At that time, there will be a determination as to whether the grapple feature will be added to the telescope. The assessment will finalize in 2008.
The James Webb Space Telescope is a 21st century space observatory that will peer back more than 13 billion years in time to understand the formation of galaxies, stars and planets and the evolution of our own solar system. It is expected to launch in 2013. The telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency. -NASA/Goddard Space Flight Center
