FCC Approves Sun-Reflecting Satellite Test; Astronomers Unimpressed

The company behind the project ultimately hopes to place 50,000 such satellites into orbit as a geoengineering measure. Astronomers have reacted with alarm, warning of potential interference with sky observations and unpredictable climate consequences.
