How Can You Find and Track Asteroids Near Earth?

It seems that every now and then we are surprised to learn that an asteroid is passing near the earth. Sometimes these are asteroids that NASA and others have been tracking for some time, but in other cases, they are newly discovered. The consequences of an asteroid hitting our planet range from relatively insignificant to catastrophic. At the University of Rochester, a team has developed a special type of camera that is capable of detecting and tracking asteroids. A sensor designed to be the eyes of a future asteroid-tracking mission has passed a critical test. The Near Earth Object Camera (NEOCam) sensor is a new infrared-light detector to improve the performance and efficiency of the next generation of space-based asteroid-hunting telescopes. It is the result of a long-term collaboration between the University of Rochester and the Jet Propulsion Laboratory (JPL), together with Teledyne Imaging Sensors.
A paper on the NEOCam sensor test will be published in an upcoming issue of the Journal of Optical Engineering.
