The space agency is apparently including a request for $100 million in its 2014 budget request to help fund the audacious asteroid capture mission, an Aviation Week report said. 
The asteroid-retrieval mission was first proposed last year by the Keck Institute for Space Studies at the California Institute of Technology in Pasadena. That study, released last April, revolved around an Asteroid Capture and Return mission that would snag a 25-foot-wide (7 meters) space rock and place it in high lunar orbit by 2025 — the deadline set by the Obama administration for NASA's human mission to an asteroid.
