In 2016, NASA established the Planetary Defense Coordination Office (PDCO) to manage the agency's ongoing mission of finding, tracking, and better understanding asteroids and comets that could pose an impact hazard to Earth.

At NASA's Jet Propulsion Laboratory in Southern California, on June 7, 2024, clean room technicians use a crane to lift the lid of the Medium Articulating Transportation System (MATS), which was used to build and transport components for NASA's Near-Earth Object Surveyor mission. Inside the MATS is the Medium Articulating Assembly Dolly (MAAD), a platform that supported the spacecraft's instrument enclosure, which was being constructed inside the High Bay 1 clean room at JPL's Spacecraft Assembly Facility in late 2024. The instrument enclosure contains NEO Surveyor's telescope, mirrors, and infrared sensors that will be used to detect, track, and characterize the most hazardous near-Earth objects, such as large asteroids or comets that could threaten our planet. NEO Surveyor is scheduled to launch no sooner than 2027.
