The great commercial takeover of low Earth orbit

Even as the scorched remains of the International Space Station sink to the bottom of the sea,  the story of America in low Earth orbit will continue. The ISS never really became what some had hoped: a launching point for an expanding human presence in the solar system. But it did enable fundamental research on materials and medicine, and it helped us start to understand how space affects the human body. To build on that work, NASA has partnered with private companies to develop new, commercial space stations for research, manufacturing, and tourism. If they are successful, these companies will bring about a new era of space exploration: private rockets flying to private destinations. They will also demonstrate a new model in which NASA builds infrastructure and the private sector takes it from there, freeing the agency to explore deeper and deeper into space, where the process can be repeated. They’re already planning to do it around the moon. One day, Mars could follow.
