Technicians and engineers inspect NASA's Near-Earth Object (NEO) Surveyor's instrument enclosure at the Space Dynamics Laboratory (SDL) in Logan, Utah, after it arrived from the agency's Jet Propulsion Laboratory in Southern California in May 2025. The instrument enclosure will house the spacecraft's telescope, which is fitted with state-of-the-art detectors and a novel cryogenic system to keep the instrument cool. The telescope, which has an aperture of nearly 20 inches (50 centimeters), features detectors sensitive to two infrared wavelengths in which near-Earth objects re-radiate solar heat. The instrument enclosure is designed to ensure heat produced by the telescope during operations doesn't interfere with its observations. As NASA's first space-based detection mission specifically designed for planetary defense, NEO Surveyor will seek out, measure, and characterize the hardest-to-find asteroids and comets that might pose a hazard to Earth. While many near-Earth objects don't reflect much visible light, they glow brightly in infrared light due to heating by the Sun. Targeting launch in late 2027, the NEO Surveyor mission is led by Professor Amy Mainzer at UCLA for NASA's Planetary Defense Coordination Office and is being managed by JPL for the Planetary Missions Program Office at NASA's Marshall Space Flight Center in Huntsville, Alabama. BAE Systems, SDL, and are among the companies that were contracted to build the spacecraft and its instrumentation. The Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder will support operations, and IPAC at Caltech in Pasadena, California, is responsible for producing some of the mission's data products.
