Also, #jwst will also be placed in an orbit where it will stay in earths shadow, so its mirrors will naturally stay very cold.
@jesustheplumber #JWST is kept cold by its sunshield, which blocks the light/heat of Earth/Sun/Moon: http://jwst.nasa.gov/sunshield.html

@jesustheplumber Yep! It's roughly the size of the moon's orbit around Earth. - Show replies
