FCC Space Mirror Approval: Legal Implications of Sunlight on Demand

Reflect Orbital is touting its space mirror proposal as sunlight on demand. According to the company, this technology could serve agriculture, power solar farms, or aid in search and rescue missions by directing concentrated light beams down to Earth. However, the commercial venture has triggered immediate pushback from the scientific community.

Astronomical Threats and Safety Hazards of Orbital Mirrors

Astronomers and international research groups are sounding the alarm over the severe disruptions these orbiting reflectors pose to nightly observations. According to a statement released by the American Astronomical Society, the potential harm includes damage to sensitive research telescope equipment, the flash-blinding of pilots and drivers, and permanent eye damage for anyone looking through a mid-sized telescope while the mirror passes overhead.

Piero Benvenuti, director of the International Astronomical Union’s Centre for the Protection of Dark and Quiet Sky from Satellite Constellation Interference (CPS), noted that the company initially appeared surprised by the sheer volume of active instruments. “They probably didn’t know that the number of telescopes, including the amateur astronomer telescopes, are huge and are dispersed everywhere in the world,” Benvenuti stated. While Reflect Orbital maintains that they enforce strict exclusion zones for astronomy, Benvenuti warned that launching 50,000 mirrors by 2035 “would be catastrophic for astronomy.”

Regulatory Loopholes and International Space Law

Questions regarding who holds jurisdiction over a five-kilometer swath of concentrated sunlight remain largely unanswered. The U.S. Federal Communications Commission (FCC) stated that these environmental and safety concerns fall outside its regulatory scope, as the agency oversees only radio, television, wire, and satellite communications.

International space law experts point out that oversight depends heavily on national legislation. According to UNOOSA, of the 193 member states, roughly 50 maintain their own national space legislation. “The honest answer to ‘how legal is it’ is that it is not a yes or no question,” UNOOSA officials explained, noting that while Article I of outer space treaties guarantees the freedom to use outer space, activities remain subject to due regard and consultation obligations owed to every other state.

Cassandra Steer, an international space law expert, suggested that individual nations might need to step in. “I think that there are environmental protection regulations within Canada where the federal government could say, actually, we are not going to allow anybody in Canada to legally purchase and use these services,” Steer said. Ram Jakhu, professor emeritus at McGill University’s faculty of law, added that formal regulations will likely materialize within five to ten years as concerns over night sky preservation grow.

Industry Response and Collaborative Mitigation Efforts

In response to mounting regulatory scrutiny, a spokesperson for Reflect Orbital emphasized that the firm welcomes oversight. “We recognize that responsible deployment at scale requires clear rules,” the company stated, adding that they want to play an active role in shaping policy alongside governments and scientists.

The company is already engaging with the IAU’s CPS to evaluate the prototype spacecraft, Earendil-1. According to Benvenuti, researchers are currently negotiating a campaign of observations to quantify the prototype’s real-world impact and verify existing simulations. Reflect Orbital confirmed that feedback from the astronomical community has already informed the design of their spacecraft and operational plans.
