NEO Surveyor (NEO Surveillance Mission)

NEO Surveillance Mission similar

NEO Surveillance Mission is a planned space-based telescope to search for near-Earth asteroids under development by NASA. The Jet Propulsion Laboratory will lead development of the mission under NASA’s planetary defense program.

The goal of the mission is to discover at least 90 percent of the near-Earth asteroids at least 140 meters in diameter.

NEO Surveillance Mission is based on the NEOCam mission that was a finalist in the previous competition for Discovery-class planetary science missions. The spacecraft is to feature a 50 centimeter telescope with a camera that operates in the infrared between 4 and 10 microns. The spacecraft would have a total mass of no more than 1,300 kilograms, allowing it to launch on a vehicle like an Atlas-5(401) or Falcon-9 v1.2 (Block 5) to the Earth-sun L-1 Lagrange point. Once in space, the mission should reach the 90% congressional goal within 10 years, with anticipated mission lifetime of 12 years.

Launch is planned no earlier than 2025.
