writes "The National Research Council issued its report on the future of space exploration on Wednesday, June 4. 2014. The report stated that the “horizon goal” for any program of space exploration in the near term (i.e. the next two decades) is a Mars surface expedition, It also started that the current NASA program, which includes a mission that would snag an asteroid, put in in lunar orbit, and visit it with astronauts is inadequate to meet that goal.
The report gave two reasons for its critique of the current NASA program. First the asteroid redirect mission would not create and test technologies necessary to conduct a crewed Mars mission. Second, NASA projects essentially flat budgets for the foreseeable future. Any space exploration program worthy of the name will cost considerably more money, with five percent increases in NASA funding for a number of years."Link to Original Source
