Should we wait to build a heavy lift rocket???

Space News recently reported of an August 19th meeting between NASA Commercial Crew Planning Lead Phil McAlister and a group of space industry executives where he pledged that regardless of what Congress does, NASA will be able to provide the $5.8 billion in funding to keep the commercial crew “space taxi” programs in place (click for article). While this is certainly welcome news to both companies such as SpaceX and Orbital, it is also welcome news to those of us who believe that pedestrian deliveries to the International Space Station can best be provided by NASA supervised commercial contractors.

What was troubling about this article however was a blurb inserted in the final paragraphs that quoted some group called the “Planetary Society.” This group has sent an open letter to legislators suggesting that they support the Obama plan to not build a heavy lift rocket until a extra orbital destination is decided upon. This is just ridiculous on its face. There are only a very few possible destinations for the cargo of an Saturn V or Ares V class heavy lift rocket and the one thing that they have in common is the fact that to get there, you need a heavy lift rocket. The rocket does nothing more than put large payloads into Earth orbit. What that payload does once it is up there has next to nothing to do with the rocket itself.

This nation needs a heavy lift rocket to serve whatever purpose may arise. That purpose may be nothing more than putting large payloads into low Earth orbit, and there is nothing wrong with that. The rest of the world, and by that I mean Russia, China, India, Pakistan, North Korea, Iran, etc., seems intent upon becoming space-faring societies. I find it impossible to believe that the United States is so willing to cede the high ground to other nations when we currently enjoy such a huge technological advantage. Does anyone believe that any of these nations would be as dedicated toward peace and cooperation in space as the United States has been over the years? Has anyone looked at the distribution of the building and operational costs associated with the “international” space station?

A heavy lift rocket is a heavy lift rocket. While it certainly cannot be considered to be a heavy lift vehicle in the mold of a Saturn V, the much deserved retirement of the Space Shuttle has left the United States with no way to put large payloads into orbit. Do we as a country want to wait on politicians and NASA administrators (not sure that they are all that different) to decide on a extra-orbital destination before we build the capability to put large payloads into LEO? I personally cannot imagine why we should do that.
