Yes, there are lots of spaceships being built right now to provide the short up and down (sub-orbital) trips. Also, people have started to design spaceships for orbital ...

If there is a permanent manned base at a great distance from Earth— on Mars, for example—the spacecraft traffic will be determined by the requirement for supplies—at least until the base could become self-sufficient by mining materials from the planet's atmosphere and surface (although this is not an option for bases in orbit). In the initial stages it would be months between ...
