U.S. President-elect Barack Obama's NASA transition team is asking U.S. space agency officials to quantify how much money could be saved by canceling the Ares 1 rocket and scaling back the Orion Crew Exploration Vehicle next year.rnObama pledged during his campaign to inject an additional $2 billion into NASA aimed in part at narrowing the gap between the space shuttle's retirement and the introduction of a successor system.
