Why in news
Scientists and international scientific societies have raised concerns over proposals by Reflect Orbital and SpaceX to deploy reflective satellites in low Earth orbit
Background
Reflect Orbital and SpaceX are proposing a vast network of reflective satellites in low Earth orbit. Scientists argue these satellites could increase night sky brightness, potentially impacting hormone secretion, migration patterns, and food webs.
Facts for Prelims
- S&TReflect Orbital and SpaceX are the entities proposing reflective satellite networks.
- FactThe proposed satellites are intended for deployment in low Earth orbit (LEO).
- EnvironmentPotential ecological impacts include disruption of migration patterns and food webs.
For Mains
Q. Discuss the environmental and biological implications of increasing satellite reflectivity in low Earth orbit and suggest regulatory frameworks to mitigate these impacts.
Dimensions to cover in your answer
- Biological disruption: Interference with nocturnal wildlife migration and hormone secretion cycles
- Regulatory vacuum: Lack of international standards for cumulative night sky brightness limits
- Human health impact: Potential disruption of human circadian rhythms due to increased light pollution
Keywords: Circadian rhythms · Light pollution · Low Earth Orbit · Ecological impact · Regulatory framework
