To be able to work on the James Webb Space Telescope was one of those life-changing events. James Webb is orbiting in an L2 orbit or Lagrange 2 orbit, which is 1.5 million kilometers from Earth. The James Webb, light comes in the front, process and instruments in the back. James Webb is an interesting telescope because it works through the premise of folks out make proposals to say, I'd like to study this galaxy with James Webb through these filters, for example. Then what you're going to do is you're going to mask each filter.
