Some astronomy experts and enthusiasts in New Brunswick are voicing concerns over a U.S.-based company’s plan to use mirrors in space to offer artificial sunlight as a commercial service. Known as Reflect Orbital, the company aims to provide “sunlight on demand” for various applications such as agriculture, solar power infrastructure, search and rescue operations, and construction projects.
Mount Allison University astronomy professor, Catherine Lovekin, criticized the project, warning that it could severely impact ground-based astronomy and stargazing activities due to the increased brightness levels compared to existing satellites. Reflect Orbital, founded in 2021, received approval from the U.S. Federal Communications Commission in July for a single mirrored satellite for testing purposes.
The company’s ambitious goal is to deploy 50,000 satellites by 2035 to reflect sunlight back to Earth, potentially affecting nighttime sky visibility. Lovekin highlighted the risks to circadian rhythms, wildlife, and ecosystems posed by disrupting the natural day-night cycle. Stéphane Picard, who operates an astro-tourism organization, echoed these concerns, emphasizing the importance of preserving dark-sky sites for tourism and environmental conservation in rural communities.
Reflect Orbital defended its project, stating that the artificial light would be directed to specific locations, minimizing visibility in most areas. The company assured that the service would be regulated, requiring permits and incorporating exclusion zones to protect astronomical observation sites. Despite these assurances, astronomy groups and international organizations have raised objections, citing potential negative impacts on stargazing experiences and ecosystem health.
In response to criticisms, Reflect Orbital emphasized collaboration with experts and adherence to brightness standards acceptable to humans and animals. While the United Nations Office for Outer Space Affairs acknowledged the lack of specific prohibitions on reflective objects in orbit, they emphasized the need for international consultation and regulatory frameworks to address concerns related to space-based services.
