SpaceX is making the largest most powerful rocket in history for the purpose of starting a colony on mars, it is fully reusable and lands by itself. SpaceX has already tested the engines, the flight profile of the upper stage have done numerous hops and landing tests and have static fired and cryo tested the booster. They have tested the stacking of the rocket and they have already built the launch platform. The thermal protection system is tested and they are very close to an orbital test flight where they will test reentry as well as the ascent and landing flight profile of the booster. On top of that NASA has been developing the space launch system as a way to get crew to travel to and create a permanent base on the moon, they have contracted both SpaceX's Falcon Heavy and the Starship to work alongside SLS to set up a Lunar gateway station in a near-rectilinear halo orbit of the moon and to land crew and cargo to the surface. Because of these projects we are only a few years away from initiating habitation on foreign planetary bodies. Let's discuss how transportation in space will be set up and evolve as these installations grow into large settlements.
