The Light and Dark Sides of NEO Surveyor's Instrument Enclosure
After arriving at the Space Dynamics Laboratory (SDL) in Logan, Utah, from NASA's Jet Propulsion Laboratory in Southern California in May 2025, the instrument enclosure for the agency's Near-Earth Object (NEO) Surveyor mission was inspected prior to thermal vacuum testing. Shown here, the enclosure stands vertically atop an articulating assembly dolly.
The shiny and black surfaces of the enclosure optimize the reflection and radiation properties of the structure. 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.
Figure A shows a closer view of the instrument enclosure's panels that are constructed from layers of aluminum.
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. Caltech manages JPL for NASA.
