NASA has completed the final inspection of the Nancy Grace Roman Space Telescope's primary mirror, which is 2.4 meters (7.9 feet) in diameter and features a silver coating just 400 nanometers thick. This telescope is designed to utilize near-infrared light for its mission objectives, which include investigating dark matter and dark energy, discovering exoplanets through direct imaging and gravitational microlensing, and studying galaxy formation and evolution. Scheduled for launch in September 2026, the Roman telescope will be positioned at the Sun-Earth Lagrange point 2 (L2), approximately 1.5 million kilometers from Earth. This location allows for stable operations with minimal fuel requirements. The Roman telescope, named after Dr. Nancy Grace Roman, has faced various challenges since its inception in 2014 but represents a significant advancement in astronomical research. The completion of the mirror inspection marks a crucial milestone in the project, paving the way for future discoveries about the universe.
