The next big subscription service could be sunlight. And it might cost $5,000 an hour

A satellite startup named Reflect Orbital has unveiled ambitious plans to launch 50,000 satellites equipped with mirrors to redirect sunlight. This initiative, dubbed "sunlight-as-a-service," would provide five-kilometer-wide beams of varying brightness levels, ranging from noon light to moonlight. The potential applications include powering solar panels, illuminating disaster zones and search-and-rescue missions, and lighting up worksites, cities, and events.

However, experts warn that the project could have severe consequences for both the natural world and astronomy. Astronomers have expressed grave concerns, calling Reflect's plans "a bullet in your head" due to the potential light pollution and disruption to ground-based telescopes. Environmentalists argue that the endeavor runs counter to the ongoing efforts to reduce light pollution.

Reflect's CEO, Ben Nowack, dismisses these concerns, stating that the company will avoid interfering with the telescopes of astronomers. However, critics remain skeptical, pointing out that the beams would be significantly brighter than light bulbs and appear as four magnitudes brighter than the moon. Consequently, it is likely that only militaries and large corporations with deep pockets would be able to afford Reflect's services, despite the altruistic branding.

Reflect has not yet launched any satellites, but it has secured approval from the Federal Communications Commission to launch a single demonstration satellite. In an attempt to bypass U.S. government oversight, Reflect has purchased two space launches in India, which will be accountable for any unintended consequences of satellites launched from within India's borders under the Outer Space Treaty.
