FCC Approves Test of Space Mirror to Reflect Sunlight

The US Federal Communications Commission (FCC) has approved a test of a giant space mirror to reflect sunlight to Earth, despite opposition from astronomers and concerns about safety and environmental impacts. The mirror, to be launched by Reflect Orbital, is intended to provide "sunlight on demand" and could cover an area about five kilometers wide. The test is a small step towards a much larger plan: Reflect Orbital aims to have over 50,000 satellites in orbit by 2035.

What happened

The FCC approved Reflect Orbital's plan to launch a satellite called Earendil-1, which will test the company's technology for reflecting sunlight back to Earth. The satellite will have a steerable thin-film reflector measuring about 60 feet by 60 feet. The reflected light is expected to span an area about three miles wide on the ground. The test is intended to demonstrate the feasibility of using space mirrors to provide solar energy and illumination.

The proposal has faced opposition from astronomers and environmental groups, who are concerned about the potential impacts on astronomy, human health, and the environment. The American Astronomical Society has raised concerns about the potential for eye damage to amateur astronomers, temporary "flash blinding" of drivers and pilots, and negative impacts on scientific research.

Why it matters

The approval of the space mirror test has significant implications for the development of new technologies and services in space. The FCC's decision is seen as a step towards advancing American leadership in space and encouraging the provision of new technologies and services to the public. However, the concerns raised by astronomers and environmental groups highlight the need for careful consideration of the potential impacts of such technologies.

The development of space mirrors and other "weird space stuff" is becoming increasingly common, with proposals for everything from space advertising to orbital missiles. The FCC's approval of the space mirror test is a sign that the agency is willing to consider innovative technologies, but it also underscores the need for careful regulation and oversight.

How to think about it

The development of space mirrors and other innovative technologies in space raises complex questions about regulation, oversight, and the potential impacts on society and the environment. As we consider the potential benefits and risks of such technologies, it is essential to take a thoughtful and nuanced approach.
