We're starting to design this new transportation system to support the International Space Station (ISS) once it's complete.
We're starting to look at the moon as a source of fuel. Maybe it's science fiction right now, but we need to start moving in that direction.
If we hit those requirements, no longer will just professional cosmonauts and astronauts from the various space agencies be able to reach the ISS, but also researchers. Only proper researchers will be able to conduct space science experiments with the proper amount of exactitude.
