Is there a future for JDEM?

Nature News: The rise and fall this year of the Joint Dark Energy Mission (JDEM)—a satellite meant to pin down the repulsive force that is accelerating the universe's expansion—is partly due to strife between two US agencies, NASA and the Department of Energy, and a third potential partner, the European Space Agency.

In addition, scientists working on the JDEM designs have not presented a unified front, owing to disagreements over the best observational method to use at a time when an influential astrophysics panel is about to prioritize the next decade's best and most organized missions.
