2026 Controversial Satellite Launch: Reflecting Light Back to Earth

The bold initiative by Reflect Orbital aims to commence in 2026, deploying satellites to reflect sunlight back to Earth. This technology seeks to illuminate dark regions for visibility and enhance energy generation. However, many astronomers express skepticism regarding the project’s feasibility and its implications for scientific research.

Reflect Orbital, a US-based company, aspires to provide “sunlight on demand.” Their first satellite is expected to launch in early 2026, illuminating ten locations as part of its inaugural “world tour.” Plans include deploying thousands of satellites fitted with extensive mirrors designed to reflect sunlight back to the Earth, catering to needs such as remote control, defense, infrastructure, and energy production.

By 2030, Reflect Orbital anticipates having sufficient satellite coverage to deliver 200 watts per square meter to solar farms on Earth, mimicking the light levels of dusk and dawn, thereby facilitating reliable energy production, especially in regions lacking natural light.

Despite these ambitions, their Federal Communications Commission (FCC) specifications suggest that a single satellite may not generate significant power. Astronomers, including members from Tucson’s Dark Sky Consulting and the American Astronomical Society, utilized these filings to underscore potential energy limitations.

As highlighted by John Valentine, a prominent scholar in the field, the reflected light would only exceed a full moon’s brightness fourfold, indicating insufficient electricity generation. In order to produce more significant light output, deploying satellites with a multitude of reflectors would be essential, presenting logistical challenges and increased costs.

Furthermore, the dynamic nature of the mirrors could pose challenges for astronomical research, since they might intermittently produce flashes of sunlight. Additionally, even micro-damage to a satellite’s reflector from tiny meteoroids could scatter light unintentionally, complicating operational efficiency.

Reflect Orbital is actively engaging with the scientific community to explore solutions for these arising concerns. As of now, the company has not responded to inquiries from New Scientist.
