A startup named Reflect Orbital aims to launch a unique satellite constellation designed to provide artificial sunlight, potentially transforming nighttime visibility. This California-based company plans to deploy up to 50,000 satellites equipped with mirrors to reflect sunlight onto designated areas on Earth.
The first prototype, named Earendil-1, is set to be launched later this year for testing. Each satellite could illuminate zones up to 3 miles (5 kilometers) with brightness levels ranging from 0.8 to 2.3 lux, significantly brighter than the natural light from a full Moon.
Reflect Orbital envisions charging approximately $5,000 per hour for the light from each mirror, aiming to support various applications such as disaster response, agriculture, and urban lighting. However, the proposal has generated backlash from astronomers concerned about the adverse effects on night sky observation and the potential for increased space debris.
In response to these concerns, DarkSky International has called for comprehensive reviews and greater public accountability before any deployment of such systems.
