|NASA's 'Webb Slinger' in Washington, D.C.||
There is more than one "web slinger" in town. In addition to the superhero, who made his third movie appearance, NASA has its own "Webb" slinger – the James Webb Space Telescope. The Webb space telescope will be much larger than the Hubble Space Telescope, its predecessor. A life-sized model of the "Webb" telescope is on the National Mall in Washington through May 12. |

annual meeting in Seattle, Washington. It stands two stories high and weighs several tons. Click image to enlarge. Credit: Rob Gutro, NASA/GSFC
The James Webb telescope will be able to look back to the beginning of time. It will find the first galaxies and will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. Launch is scheduled for 2013.
"There's more than just one similarity between the web-slinging superhero and the James Webb telescope," said John Decker, Deputy Associate Director for the James Webb Space Telescope Project at NASA's Goddard Space Flight Center, Greenbelt, Md. "The sunshield on the spacecraft is actually shaped like a giant spider web, when you look at it from the top."
During this week, visitors to the Nation's Capitol will be able to see the life-sized model of NASA's latest "superhero," and get a picture taken next to it. The model is on display in front of the Smithsonian's National Air and Space Museum on the National Mall, Washington.

NASA and Northrop Grumman, the contractor who built the model, has set up information booths next to the model, where visitors can get information and educational materials, and speak with people who are involved in the project to build the real James Webb Space Telescope.
The full-scale telescope model was built to give the viewing public a better understanding of the size, scale and complexity of this breakthrough satellite. Specifically designed for an environment subject to gravity and weather, the model is constructed mainly of aluminum and steel, weighs 12,000 lbs., and is approximately 80 feet long, 40 feet wide and 40 feet tall. A specially manufactured material imported from France called "Ferrari Precontraint" allows the sunshield to 'breathe.' The model requires 2 trucks for shipping, and assembly takes a crew of 12 approximately four days.

The telescope model has been "Webb-slinging" since 2005 to Seattle, Wash.; Colorado Springs, Colo.; Paris, France; Greenbelt, Md.; Rochester, N.Y.; and Orlando, Fla. Funds used to build this model were provided solely by Northrop Grumman.
The model display is part of "Public Service Recognition Week 2007," which runs from May 10 through 13. The theme of the week is "Safety, Science, Security, Technology." This annual national event is sponsored by the Council for Excellence in Government, Employees Roundtable, and it honors men and women who serve America in the Federal, state and local governments.
