WISE Finds Fewer Asteroids Near Earth
In "Space Rock Census" Amy Mainzer, principal investigator for the Wide-field Infrared Survey Explorer (WISE) mission, reveals some new observations about space rocks in our solar system in these videos from NASA Jet Propulsion Laboratory. The WISE mission is helping scientists understand the true number, sizes, locations, and physical make-up of asteroids and comets. In the second video, learn about observations by WISE that show there are significantly fewer near-Earth asteroids in the mid-size range than previously thought. This video is available in both English and Spanish audio, along with corresponding closed captions. This resource is part of the NASA Planetary Sciences Collection.
