Capturing the Rock

NASA has released new images and a short video for the proposed mission to capture, redirect and then examine (probably a carbonaceous type) asteroid using a combination of robotic and crewed vehicles. I really like this mission, but I wonder if NASA can carry it through given the near lack of enthusiasm (and therefore support) from the Congress and the Administration towards the agency. There's a lot of incremental progress in the agency, but any big project seems doomed to be underfunded, constantly retasked and the like.
