The NASA Reauthorization Act of 2026 aims to secure ongoing funding and support for NASA, facilitating its missions in space exploration, science, aeronautics, and education. The legislation is designed to maintain the United States' leadership in space activities and enhance its global competitiveness. It authorizes approximately $24.4 billion in funding for NASA programs for the fiscal year 2026, with significant allocations directed towards the Artemis program, which focuses on returning humans to the Moon and eventually sending astronauts to Mars.
