Reflect Orbital tests nighttime sunlight reflection, draws criticism
A US startup demonstrated a satellite with a large mirror that reflected sunlight at night in rural California, prompting backlash from residents, environmental groups and astronomers.
Residents of a rural California community reported a bright beam of light shining from the nearby mountains after midnight, an incident linked to a test by the startup Reflect Orbital. The company, which has secured Federal Communications Commission approval to launch a demonstration satellite next year, aims to deploy up to 50,000 satellites equipped with 59-foot mirrors that can direct three-mile-wide beams of sunlight onto the Earth's surface.
Reflect Orbital says the technology could aid emergency responders and search-and-rescue teams operating in darkness and could potentially power solar panels at night. A company spokesperson told reporters that search-and-rescue agencies would be the first customers and that the firm would continue to work closely with local communities and authorities.
Environmental organization Earthjustice and a coalition of astronomers and local residents have condemned the test, warning that altering the natural day-night cycle could disrupt wildlife, affect human sleep patterns and increase light pollution. Jan Hasselman, a senior attorney with Earthjustice, described the project as "idiotic" and called for broader discussion and analysis before any large-scale deployment.
