Earendil-1

Overview

The first demonstration satellite: a 142 kg spacecraft carrying an aluminized thin-film reflector roughly 18 meters on a side, folded into a container about the size of a microwave oven and deployed on orbit at 600 to 650 km. It is designed to steer a reflected beam onto a spot several kilometers wide at approximately full-moon brightness for up to five minutes per pass, within about two hours of local sunset.

FCC license granted July 9, 2026; launch on a SpaceX rideshare still expected later in 2026, but as of September 12, 2026 Reflect has not named the mission or a date, and the license remains under a pending Application for Review
