The situation with the fiscal year 2026 budget for the United States is, to put it politely, kind of a mess.
The White House proposed a budget earlier this year with significant cuts for a number of agencies, including NASA. In the months since then, through the appropriations process, both the House and Senate have proposed their own budget templates. However, Congress has not passed a final budget, and the new fiscal year begins on October 1.
As a result of political wrangling over whether to pass a "continuing resolution" to fund the government before a final budget is passed, a government shutdown appears to be increasingly likely.
