NEO Surveyor
Space-based infrared telescope dedicated to detecting and characterizing near-Earth objects (asteroids and comets) that could threaten Earth. Will orbit at L1 point and discover an estimated 90% of asteroids larger than 140 meters. Critical for planetary defense — early detection enables deflection missions like DART.
