According to budget documents seen by The Verge, the Trump administration is preparing to end support for the International Space Station program by 2025. As a result, 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. From the report: The draft may change before an official budget request is released on February 12th. However, two people familiar with the matter have confirmed to The Verge that the directive will be in the final proposal. We reached out to NASA for comment, but did not receive a response by the time of publication. Any budget proposal from the Trump administration will also be subject to scrutiny and approval by Congress. But even announcing the intention to cancel ISS funding could send a signal to NASA's international partners that the U.S. is no longer interested in continuing the program. Many of NASA's partners still have yet to decide if they'd like to continue working on the station beyond 2024. 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 U.S. 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.
