The Turbo rocket is the only rocket with the delta-V to get back to earth from the moon.
A SpaceX BFR needs 5 refueling missions to go to the moon and back. SpaceX BFR would be $12k per kg to the moon and back. This is ~16x more expensive than the turbo rocket. The Turbo Rocket architecture represents a new paradigm for access to space economics.
Large payload fractions of 35-50%, Low Construction Cost and Full Reuse
Cost to LEO: less than $85/kg w/10 flights
Cost to Luna: less than $715/kg w/10 flights
Staged Combustion: Lowest Cost to LEO
Nuclear Thermal: Lowest Cost for Near Earth Return and Larger Payloads to Everywhere
