Imagine a scenario where after a long day at work, you’ve finally settled into bed only to witness the sky outside your window suddenly light up as bright as day. This surreal experience could become a reality if a U.S. company’s ambitious plan comes to fruition.
Reflect Orbital, the company in question, aims to launch massive mirrors into space to “sell sunlight after dark.” While this proposal has sparked concerns among astronomers regarding light pollution and the degradation of the night sky due to satellite constellations, the California startup insists that its initiative could address energy challenges and provide illumination for emergency situations.
Despite the company’s assertions, astronomers remain skeptical. Aaron Boley, an astronomer and professor at the University of British Columbia, has criticized Reflect Orbital for what he perceives as misrepresentations on their website. He highlighted the potential issues with the company’s claims about reducing light pollution using natural sunlight.
Reflect Orbital has submitted a request to the U.S. Federal Communication Commission to launch its first satellite, EARENDIL-1, which would utilize satellites to reflect sunlight onto specific locations like solar farms post-sunset. The company has proposed various satellite sizes, ranging from 10 x 10 meters to 54 x 54 meters. However, experts argue that to effectively illuminate a solar farm, thousands of satellites may be necessary even with the largest size option.
The concept of space mirrors is not new, dating back to the 1920s. Russia deployed Znamya 2, a 25-meter space mirror, in 1993, which produced a five-kilometer bright spot before burning up over Canada. While the U.S. and the European Space Agency have explored similar ideas, none have materialized due to feasibility concerns.
Reflect Orbital’s plan has raised questions about its potential consequences, including the impact on wildlife and observatories. Concerns have been raised about the unintended effects of the mirrors on animal behavior and the disruption of migratory patterns. Additionally, there are worries about interference with observatories and radio frequencies, similar to the challenges faced with SpaceX’s Starlink satellites.
In conclusion, while Reflect Orbital’s proposal offers potential solutions to energy and lighting needs, it poses significant environmental and technical challenges that must be carefully considered before implementation.
