When I say here, I could do an entire mars settlement program (evergreen) with just one year of SLS/Orion funding using just the FH for launch (13.2 ton is not only enough but preferred to larger vehicles.)
Assuming each year the interest pays for a FH launch with payload. That's two landers every 26 months leaving a habitat in mars orbit for a growing space station. Assuming just one ton of payload per lander to the surface of mars or two crew with a month of supplies and personal property.
Supplies will continuously be sent until there is absolutely no doubt the colonists have a good start. Only then will colonists follow.
We will wait until we can send a minimum of six colonist on the first mission, then those colonist will decide what we send in the following landers.
It is expected that once living on mars is demonstrated, others will fund colonists in addition to those we send every launch window.
