US astronauts may soon need to wish upon a star if they ever want to explore Earth’s final frontier again.

The International Space Station might lose its support and funding by 2025 if the Trump administration has its way, according to a draft budget proposal reviewed by The Verge.

Without the ISS, US astronauts could be grounded until NASA produces new vehicles for its deep-space travel plans, according to the report.

The draft may change before it is presented for an official budget request Feb. 12, but according to The Verge, sources have confirmed that the directive to end funding will be part of the final proposal.

NASA did not respond to the news outlet’s request for comment about the report.

Budget proposals from the White House are subject to congressional scrutiny and approval — but even announcing the intention to cancel ISS funding could signal NASA’s partners abroad that the US is no longer interested in continuing the program.

Many of the space agency’s partners have yet to decide if they’d like to continue working on the ISS beyond 2024.
