The deep-space observatory needs to stay ultra-cool to do infrared observations of the early universe.
to keep it protected from the worst of solar radiation fluctuations, but the observatory still experiences some changes as the angle of the sun shifts upon the sunshade, Smith said.
Webb will start the test in a"hot attitude," representing 0 degrees pitch. It will stay there for five days to stabilize, also allowing teams to take measurements from Earth. Then the team will turn Webb to a colder attitude, roughly +40 degrees pitch. Here, the observatory's near-infrared camera will be tested for 24 hours to see if there are any effects on the optics, and then the telescope's stability will be monitored for 12 hours to see how it performs with the thermal change, Smith said.
The telescope will sit in this freezer mode for about a week to allow the temperatures to further stabilize, before slewing once again to a hot attitude. For this second round in the heat, Webb will use both NIRCam and its fine guidance sensor to collect stability data. The mid-infrared instrument will also be deployed in hot and cold attitudes"to understand how the changing thermal environment affects the mid-infrared background levels," Smith added.
