James Webb Space Telescope will observe 100 galaxies at once

“One of the rules for building spacecraft is to have as few moving parts as possible,” Andy Bunker, Oxford University astrophysicist, grins. “And that’s why we have built something that has a quarter million shutters.”

Bunker is talking about NIRSpec, the Near Infrared Spectrograph, one of the four instruments on the James Webb Space Telescope, that are just getting ready to open their eyes to the cosmos. He is one of seven European scientists that have shaped the design of NIRSpec (which is funded by the European Space Agency), and is now eagerly awaiting the moment when the instrument starts delivering data.
