  • The ISS is a fantastically capable laboratory at the closest possible distance to Earth (i.e. least expensive & fastest access), and it???s the perfect place to test out the things we???re going to need to move permanently beyond LEO. If you can???t see that, then I don???t see you as a true space advocate.
