NASA is moving forward with plans to launch an infrared telescope that could detect asteroids on a collision course with Earth. Its launch could come by the middle of the next decade, Thomas Zurbuchen, NASA’s associate administrator for science in Washington, D.C., said today at a meeting of an agency advisory panel.
The Near-Earth Object Surveillance Mission, which will cost $500 million to $600 million, grows out of long-gestating plans for the Near-Earth Object Camera (NEOCam), first proposed by NASA’s Jet Propulsion Lab (JPL) in Pasadena, California, nearly 15 years ago. Such a scope is essential for meeting a congressional requirement that NASA detect 90% of all potentially hazardous asteroids and comets of at least 140 meters in diameter by the end of 2020. The telescope will likely end up with a different name, but the mission is the same, says Mark Sykes, CEO of the Planetary Science Institute in Tucson, Arizona, and a member of NEOCam’s science team. “There is no independent or new spacecraft or operational design here. This mission is NEOCam.”
