NASA Pondering A Future Grapple On The James Webb Space Telescope
"When it launches in 2013 the James Webb Space Telescope will settle in an orbit roughly one million miles from the Earth. That distance is currently too far for any astronaut or any other existing NASA servicing capability to reach. Therefore, NASA is doing everything necessary to design and test the telescope on the ground using techniques that will ensure that it deploys and operates reliably in space."

NASA Pondering A Future Grapple On The James Webb Space Telescope
"When it launches in 2013 the James Webb Space Telescope will settle in an orbit roughly one million miles from the Earth. That distance is currently too far for any astronaut or any other existing NASA servicing capability to reach. Therefore, NASA is doing everything necessary to design and test the telescope on the ground using techniques that will ensure that it deploys and operates reliably in space."

NASA Pondering A Future Grapple On The James Webb Space Telescope
"When it launches in 2013 the James Webb Space Telescope will settle in an orbit roughly one million miles from the Earth. That distance is currently too far for any astronaut or any other existing NASA servicing capability to reach. Therefore, NASA is doing everything necessary to design and test the telescope on the ground using techniques that will ensure that it deploys and operates reliably in space."
