This is a photo of the James Webb Space Telescope full-scale model that was set up in Dublin, Ireland, in June 2007.
The full-scale, life-size Webb model is as big as a tennis court. The model was built by NASA's prime contractor to provide a better understanding of the size, scale, and complexity of the observatory. The model is constructed mainly of aluminum and steel, weighs 12,000 pounds, and is approximately 80-feet long, 40-feet wide, and 40-feet tall. The model requires two trucks to ship it, and assembly takes a crew of 12 approximately four days. The Webb telescope full-scale model will be on display at the South by Southwest Interactive Festival in Austin, Texas, on March 8-10, 2013.
