NASA Commercial Space Capabilities office and SpaceX have a 24 page agreed plan to develop the SpaceX starship into a low earth orbit space station design by 2028. This is unfunded and aspirational.

Need proven safe starship. After using it for package delivery with ten thousand international cargo flights per year hopefully in the 2025-2028 timeframe. High volume human orbital and high volume rocket passenger flight have very similar requirements for proven safety.
