CPS SatCons 101 Training Module 4

This is the first of two SatCons 101 modules describing the impacts of the operation of large satellite constellations on astronomy. In this module, the effects on optical and infrared astronomy in particular are presented. Examples are provided, including the presence of bright streaks in astronomical images; how satellites can affect spectroscopic observations; and the tendency of satellites and space debris to raise the diffuse brightness of the night sky. Lastly, it considers how thermal radiation from satellites and debris can harm infrared astronomy.
