Startup Aims to Light Up Night Sky, Ignites Debate
26 Oct
Summary
- Company plans thousands of space mirrors to illuminate Earth at night.
- A recent California test prompted concerns from scientists and locals.
- Critics cite risks to wildlife, sleep cycles, and stargazing.
A US startup named Reflect Orbital is planning a controversial project to launch 50,000 satellites equipped with mirrors into space over the next decade. The ambitious goal is to reflect sunlight onto specific areas of Earth during the night. The company recently conducted a demonstration near Lone Pine, California, using large mobile lights to simulate the effect, which reportedly caused confusion and alarm among local residents.
This demonstration simulated beams of light with intensity ranging from moonlight to full sunlight. Reflect Orbital claims its technology could aid search-and-rescue teams, illuminate crops, and potentially provide solar power. However, the Federal Communications Commission (FCC) has approved an initial demonstration satellite for launch next year, sparking significant backlash.
Environmental groups and astronomers have voiced strong opposition, warning of severe ecological disruption. They argue that altering the natural rhythm of day and night could harm wildlife, disrupt human sleep cycles, and exacerbate light pollution, obscuring the stars. Concerns have been raised that 50,000 such satellites could fundamentally change the night sky as we know it.
These critics have urged the FCC to reconsider its approval, citing potential harm to animals that rely on predictable night cycles for survival. Astronomers are particularly concerned about increased glare impacting observations and a potential rush of satellite deployments. Reflect Orbital has stated it is engaging in discussions to avoid sensitive areas like astronomical sites and national parks.
