Submission + - NASA Pitches Heavy Lift Vehicle to Congress (spacenews.com)
BJ_Covert_Action writes: Well, Congress demanded, last year, that NASA develop a budget plan and proposal for a new heavy lift vehicle in light of the Ares V cancellation. Recently, NASA gave Congress just what they wanted. On January 11th, Douglas Cooke pitched an interim report to Congressional members detailing the basic design concepts that would go into a new heavy lift vehicle. Congress required that the new heavy lift vehicle maximize the reuse of space shuttle components as part of its budget battle with President Obama last year. As a result, NASA basically copy-pasted the Ares V design into a new report and pitched it to Congress on the 11th. The proposed vehicle will require the five segment SRB's that were proposed for the Ares V rocket. It will utilize the SSME's for it's main liquid stage. It will reuse the shuttle external tank as the primary core for the liquid booster (the same tank design that is currently giving the Discovery shuttle launch so many problems). And it will utilize the new J-2X engine that NASA has been developing for the Ares V project as an upper stage. In other words, NASA proposed to Congress exactly what Congress asked for.
The catch is, NASA also admitted that they will not be able to complete the proposed rocket on the budget that Congress has given them. Neither will they be able to finish the rocket on time. Finally, NASA has commented that a current study being conducted by 13 independent contractors is still being conducted to determine if there is a better design out there that NASA has, 'overlooked.' NASA has stated that, should that study finds any alternate, interesting designs then, they will need to consider those seriously.
