The Senate Commerce, Science and Transportation Committee has included in its appropriations bill one last flight for Atlantis in 2011 and a "back to the drawing board" approach to Constellation; requiring a new heavy lift system to be ready by 2016--about the same development time as the Saturn V.
Left for later is what to do with the heavy lift rockets come 2016, and we should also work to adopt and fund a true timetable to go to the Moon, Mars and an asteroid. The administration's vague plans won't get us there.
