NASA currently is constrained in what policies it can implement by the 2010 budget continuing resolution and by the Shelby restriction in the 2010 NASA budget not to do anything that constitutes a cancellation of the Constellation program.

Furthermore, regarding the heavy lift launcher program, even the Authorization bill says NASA should do what is practicable and doesn’t actually command NASA to build the HLV with ATK boosters.
