FCC Approves Test of Space Mirror for Solar Energy
The US Federal Communications Commission has approved a test of a space mirror, Earendil-1, to reflect sunlight for extra energy and lighting. The mirror, launched by Reflect Orbital, will cover a 5km area and require repointing every 4 minutes. The company plans to deploy 50,000 satellites by 2035 for various industrial sectors, raising concerns about human health, astronomy, and environmental impacts.
Key points
- The US FCC has approved Reflect Orbital's test of the Earendil-1 space mirror, despite opposition from astronomers and public safety concerns.
- The mirror will cover a 5km area and require repointing every 4 minutes, with plans to deploy 50,000 satellites by 2035.
- Reflect Orbital claims the satellites will be used in agricultural, emergency response, and industrial sectors, but critics raise concerns about human health and astronomy impacts.
- The FCC has stated that safety concerns are unrelated to their role in authorizing radiofrequency spectrum use.
- Reflect Orbital's proposal has sparked debate about the potential effects on circadian rhythms, pilot safety, and sensitive detectors in research telescopes.
The US Federal Communications Commission (FCC) has approved a test of a space mirror, Earendil-1, to reflect sunlight for extra energy and lighting. The mirror, launched by Reflect Orbital, will cover a 5km area and require repointing every 4 minutes. The company plans to deploy 50,000 satellites by 2035 for various industrial sectors, including agriculture, emergency response, and other industries.
Critics have raised concerns about the potential impacts on human health, astronomy, and the environment. The light from the mirror could disrupt circadian rhythms of plants, animals, and humans, while flashes during repointing could affect pilots and drivers. Sensitive detectors in research telescopes and star-tracking cameras on lower altitude satellites could also be overloaded and damaged.
Reflect Orbital has branded itself as 'the sunlight company' and claims that the satellites will provide a reliable source of energy and lighting. However, the FCC has stated that safety concerns are unrelated to their role in authorizing radiofrequency spectrum use. The approval of the test has sparked debate about the potential effects of the satellites and the need for further regulation.
As the FCC continues to authorize the use of space-based technology, concerns about the impacts on the environment and human health are growing. The Reflect Orbital proposal is just the latest example of the complex issues surrounding the use of space-based technology and the need for careful consideration of the potential consequences.
