The structure of the James Webb space-telescope which is to replace Hubble in 2016 is now so near completion, that NASA has testet it in the G-accelerator also used to train astronauts During the testing process, as the ISIM structure is being spun and shaken, engineers take measurements to compare with their computer models. If there are discrepancies, the engineers hunt for the reasons so they can address them. The huge centrifuge will spin at speeds close to 11 rpm, exposing the ISIM structure to about 10G or 10x the force of gravity on Earth's surface. SEE MORE at NASA |
