The Trump administration is preparing to end support for the International Space Station program by 2025, according to a draft budget proposal reviewed by The Verge. Without the ISS, American astronauts could be grounded on Earth for years with no destination in space until NASA develops new vehicles for its deep space travel plans.

The International Space Station has been an ongoing program for more than two decades. It costs NASA between $3 to $4 billion each year, and represents a more than $87 billion investment from the US government. It’s become a major hub for conducting both government and commercial experiments in microgravity, as well as testing out how the human body responds to weightlessness.

The ISS is at the end of it's planned life cycle in any case. I wonder if the next station will be completely commercial.
