The model is made of aluminum and steel, weighs 12,000 lbs., and is 80 feet high x 40 ft wide x 40 ft tall. The model visited a number of sites, including Dublin, Ireland, where it is pictured here in June 2007. On land, the model travels in 2 trucks and it takes 12 people 4 days to assemble it. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/MoseleyJWSTModeldublin_hires/MoseleyJWSTModeldublin_hires.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-JWST/NASA-JWST.dc.xml The JWST will have a large mirror, 6.5 meters (21.3 feet) in diameter. The mirror is being built in segments and will be mounted on a structure that will fold up to fit into a rocket. The mirror will then unfold after launch. In this picture, a team of engineers and technicians from NASA and Ball Aerospace prepare to load three of the JWST mirror segments into a test chamber at NASA’s Marshall Space Flight Center in Huntsville, Alabama. There, they will subject the segments to temperatures reaching minus 414 degrees Fahrenheit -- ensuring the mirror segments can withstand the extreme temperatures of space. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-JWST/NASA-JWST.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-Microshutter-NIRSPEC/NASA-Microshutter.dc.xml Many of the objects that JWST will study, such as the first galaxies to form after the Big Bang, are so faint, that its giant mirror must stare at them for hundreds of hours in order to collect enough light to form a spectrum. In order to study thousands of galaxies during its 5 year mission, the NIRSpec is designed to observe 100 objects simultaneously. The NIRSpec will be the first spectrograph in space that has this multi-object capability. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-Microshutter-NIRSPEC/NASA-Microshutter.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
