Administrator Faces Skeptical Senators Over Proposed Cuts

NASA Administrator Jared Isaacman defended the Trump administration’s proposed 23% budget cut before a skeptical Senate Appropriations Subcommittee. The proposed cuts would reduce the Science Mission Directorate by 47% and increase Artemis human spaceflight funding to $8.5 billion. The hearing was part of a series of congressional appearances by Isaacman, who argued that the cuts are necessary to address bureaucratic inefficiency and focus on the Moon. The proposal has faced significant resistance from Congress, with the Senate subcommittee chair and ranking member aligned against the cuts. This was reported by Unknown Source.
