Is the Constellation program officially terminated?

Just as the title says did Obama officially terminate the Constellation program and if not when would it be official when it will or will not be cancelled. Thank you for your help and any links would be appreciated.Is the Constellation program officially terminated?http://www.spacepolitics.com/2010/04/Is the Constellation program officially terminated?Unknown. Everyone would say yes but Obama is having a huge NASA summit on april 15th in which he will detail his plans for the future of the space program. Watch for that. No one knows what the hell he is going to talk about.Is the Constellation program officially terminated?The 2011 NASA budget officially cancels the constellation program. See the first source. NASA will contract with private companies for launch services. I expect Space Exploration Technologies to be the main contractor. They already have a contract for 12 cargo flights to the space station and they are actively seeking a contract for crew transport. See the second source. I expect great things from SpaceX. I have been watching this new company closely for several years now and they are absolutely awesome!
