Mars hopping rockets(?)

The Next Big Future reports on a unique concept in which rocket powered rovers would gather fuel from the  Martian atmosphere, heat the fuel with radioisotope thermal source, and boost/hop across the Martian landscape. NBF notes that the Opportunity rover covered 25 km in 7 years whereas a 'hopper' could cover twice that distance in a single year.
