Background
The International Space Station is a modular research laboratory in low Earth orbit, jointly operated by NASA, Roscosmos, ESA, JAXA, and the Canadian Space Agency since 1998. At roughly 420 kilometres altitude, it orbits Earth every 90 minutes and has been continuously crewed for over 25 years, the longest unbroken human presence in space.
In the Artemis context, the ISS faces a $1.1 billion budget cut under the FY2027 NASA proposal, part of the White House strategy to concentrate funding on lunar exploration while drawing down low Earth orbit operations. NASA plans to deorbit the station by 2030 and transition to commercial replacements, though none have yet demonstrated crew-rated capability.
The tension is structural: the ISS produces more peer-reviewed science annually than any other NASA programme, yet the agency treats it as legacy infrastructure competing with Artemis for the same budget. Every dollar shifted from ISS to SLS is a trade between proven scientific return and unproven exploration ambition.
