Despite proposed science cuts, NASA boss says 'We haven't canceled anything yet'

The Trump administration has proposed cutting NASA's budget by $5.6 billion (23%) in FY2027, with the Science Mission Directorate facing a 46% reduction to $3.9 billion. Multiple flagship missions including the Habitable Worlds Observatory and NASA's contribution to ESA's Mars rover face jeopardy. NASA Administrator Jared Isaacman told Congress that no missions have been canceled yet despite the proposed cuts.
