Boeing, SpaceX, Lockheed?

  my guess is multiple groups. Having uninterrupted access to LEO is crucial for long term habitation and exploration of space. We can't afford to stand down our entire manned program just because one launch platform is not available either due to supply or grounding in an event such as STS-51L or STS-107.
