Basically, it is the difference is between landing a few times on the Moon to check off a box before going “on to Mars” or living and working on the Moon, including using its resources to create and extend a reusable, refuelable transportation infrastructure, to allow routine access to any point in cislunar space.
I page my sisters, silent lights cast wide in cislunar space.
With ISRU derived propellants and with local industrial development along with local food production, we can change the entire cost structure of operating in cislunar space.
And this would be getting out of the cislunar system.
Just the smart transportation architecture can cut the cost of cislunar transport by a lot and instead of a few humans per year we can send many per month to the Moon.
This is fine if your goal is to do lunar "touch-and-go" and "on to Mars" (which seems to be the mindset of the agency) but it does not lead to a build-up of reusable, permanent infrastructure on the Moon, permitting us to recoup our investment through resource extraction and the creation of a cislunar spaceflight systems.
Develop heavy lift cislunar Ion propulsion systems for large cargo movement within the Inner solar system.
A reusable cislunar human and cargo transport, coupled with a reusable single stage to orbit (Lunar) transit vehicle, and we have the critical elements needed.
In the case of spaceflight, it is to gradually develop a true space faring infrastructure, one that will first take people and machines beyond LEO into cislunar space, and then into planetary space.
I believe that we should expand our economic sphere to encompass cislunar space, our Moon, the asteroids, Mars, the Asteroid Belt, Jovian space, and beyond.
