According to Y!, the new "double" mars rover mission may be cut in half by NASA. The original mission was to send two new Mars rovers to the red planet mid 2003. Schedule, money, and time all are paying a critical role while NASA reviews the project, and it is anticipated that they'll cut one of the two rovers from the mission.
Its too bad to see any space mission cut in any way. This is another great arguement on commercializing space.
