The spacecraft is being developed by NASA’s Jet Propulsion Laboratory (JPL). The NEO Surveyor mission is led by the University of Arizona. “By searching for NEOs closer to the direction of the Sun, NEO Surveyor will help astronomers discover impact hazards that could approach Earth from the daytime sky,” Mainzer said. The telescope also will help planetary scientists discover NEOs more quickly. It will be capable of detecting both bright and dark asteroids, which are the most difficult type to find.īy using sensors that operate in the infrared, NEO Surveyor will be able to make accurate measurements of NEO sizes and will gain valuable information about their composition, shapes, rotational states, and orbits. NEO Surveyor consists of a single scientific instrument: a nearly 20-inch (50-centimeter) diameter telescope that operates in two heat-sensing infrared wavelengths.

These images were taken by the Deep Space Network's Goldstone Deep Space Complex near Barstow, California. Near-Earth asteroid 2016 AJ193 drifted past Earth in August 2021 at a distance of 2.1 million miles (about 3.4 million kilometers). These are the objects large enough to cause major regional damage if they impacted Earth. “NEO Surveyor will have the capability to rapidly accelerate the rate at which NASA is able to discover asteroids and comets that could pose a hazard to the Earth, and it is being designed to discover 90 percent of asteroids 140 meters in size or larger within a decade of being launched,” said Mike Kelley, NEO Surveyor program scientist at NASA Headquarters.Īfter launch, NEO Surveyor will conduct a five-year baseline survey to find at least two-thirds of the potentially hazardous near-Earth asteroids larger than 460 feet (140 meters). NASA successfuly tested one planetary defense deflection technology with its Double Asteroid Redirection Test, (DART) mission on Sept. The planetary defense team needs to learn about potentially hazardous NEOs as early as possible to either prevent an impact with Earth, or to try to minimize the damage from an impact. This information is vital to NASA’s Planetary Defense Coordination Office (PDCO). “NEO Surveyor would improve NASA’s ability to determine the size and other characteristics of newly discovered NEOs, ” said Amy Mainzer, the principal investigator for NASA’s NEO Surveyor.
