The U.S. FCC recently cleared Hawthorne-based startup Reflect Orbital to launch " Eärendil-1 ," an 18-meter-wide orbital mirror designed to reflect sunlight back to specific locations on Earth at night . The company aims to sell on-demand artificial twilight for solar farms, disaster relief, and round-the-clock construction. [ 1 , 2 , 3 ] How it Works The concept relies on large, ultra-lightweight deployable reflectors (made of materials like mylar) that fold up during launch and expand once in low Earth orbit. [ 1 , 2 , 3 ] Targeted Beams: By precisely angling the mirror, it can direct a beam of sunlight onto dark, predetermined coordinates. [ 1 , 2 , 3 , 4 ] Brightness: The beam is adjustable and at its maximum can appear brighter than the full Moon, casting up to 36,000 lux (daylight brightness) if fully concentrated, though commercial setups will likely aim for softer, moonlight-level illumination. [ 1 , 2 , 3 ] Control: The mirrors can be rotated out of position, ...
