An Aerospace Startup Just Got Approval to Test Beaming Sunlight to Earth. Here's Why Experts Are Worried—and Petitioning
By 2035, Reflect Orbital aims to launch up to 50,000 satellites equipped with mirrors to provide sunlight to Earth-based solar panels. Critics are concerned about impacts on wildlife, astronomy research and human health
A California-based startup called Reflect Orbital has been granted permission to test a satellite that will beam sunlight from space to Earth. The goal is to extend the working hours of solar panels, providing clean energy beyond daylight hours. The test spacecraft, Earendil-1, will be equipped with a 59-foot by 59-foot mirror and will operate in low-Earth orbit.
Reflect Orbital aims to launch 36 such satellites by the end of next year and up to 50,000 by 2035. However, experts are expressing concern about the potential impacts on wildlife, astronomy research, and human health. Some have even petitioned the Federal Communications Commission (FCC) to revoke its approval. Environmental groups argue that the technology is untested and could disturb nocturnal animals and interfere with astronomy studies.
