US President Donald Trump has proposed a significant reduction in scientific funding for NASA in fiscal year 2026 - down to 3.9 billion dollars from 7.3 billion dollars in 2024. This decision may deprive key projects such as the delivery of Martian soil and the launch of the Nancy Grace Roman space telescope in autumn 2026 of support. Funding for space missions is planned to be cut by 50%, and the budget of the astrophysics department is to be reduced by nearly 70%. The proposal was directed to NASA leadership on April 10 as part of refining the budget request for the next fiscal year. The final decision on funding will depend on the US Congress, which has the right to review and adjust the budget plans.
