Lockheed Martin unveils Space Shuttle replacement

Vegan Bob writes "Lockheed Martin released its proposal for the Crew Exploration Vehicle (CEV) in a recent Popular Mechanics article. NASA will choose this vehicle scematic or opt for the yet-released Northrop Grumman design in 2008. The CEV will replace the Space Shuttle program, and will eventually go to the moon (between 2015 and 2020)."
