Presidential budget proposals are wish lists that often bear little resemblance to final congressional budgets. The Orbiting Carbon Observatory missions have already received funding from Congress through the end of the 2025 fiscal year, which ends Sept. 30.
Draft budgets that Congress is
currently considering for next year keep NASA funding basically flat. But it's not clear whether these specific missions will receive funding again, or if Congress will pass a budget before current funding expires on Sept. 30.
