Overall Summary
Representative Castro's strong ties to the Southwest Research Institute (SwRI) in his district, a major recipient of NASA science contracts and grants, suggest a foundational interest in NASA's scientific endeavors. His past legislative action supporting space science collaboration and his office's explicit inclusion of NASA-related projects in Community Project Funding further indicate a willingness to advocate for federal investment in this area, especially given the significant local economic and scientific benefits.
However, his lack of direct committee oversight on the House Science, Space, and Technology Committee means he may not be a primary driver of NASA's overall budget. Advocates should be prepared to connect the proposed 47% budget cut to specific, tangible impacts on SwRI and other local research institutions, framing increased NASA science funding as a critical investment in his district's economy, STEM workforce, and scientific leadership, rather than solely a national priority.
Preparation Recommendations
Consider highlighting specific, ongoing NASA science missions led by the Southwest Research Institute (SwRI) in San Antonio, emphasizing their direct economic impact and the high-profile scientific discoveries originating from his district.
Explore how increased NASA science funding can directly support STEM education and workforce development initiatives within his district, particularly at Hispanic-Serving Institutions like UT-San Antonio, aligning with his past advocacy and family background.
Look into potential local NASA science-related projects or STEM education programs that could be strong candidates for Community Project Funding, demonstrating how federal investment can directly benefit his constituents through his office's initiative.

Opportunities
Local NASA-affiliated Research: The Southwest Research Institute (SwRI) in San Antonio, TX, within Representative Castro's district, has received substantial NASA contracts and grants for science activities in heliophysics, planetary science, and lunar exploration, indicating a significant local economic and scientific stake in NASA's Science Mission Directorate. (USAspending, FY2022-FY2024)
Engagement in Community Project Funding for NASA: Representative Castro's office actively solicits and supports Community Project Funding requests, explicitly listing "NASA Safety, Security, and Mission Services" as an eligible category for local projects, including scientific research and STEM education activities, indicating a willingness to direct federal funds to NASA-related work in his district. (U.S. Congressman Joaquin Castro, House.gov)
Support for General Federal Research Investment: Representative Castro announced nearly $3 million in federal grants for research at UT Health San Antonio in May 2024, reflecting a general posture of advocating for federal investment in scientific research within his district. (U.S. Congressman Joaquin Castro, 2024-05)
Advocacy for Research at Hispanic-Serving Institutions: In September 2025, Representative Castro publicly condemned the termination of discretionary grants for Hispanic-Serving Institutions (HSIs), such as UT-San Antonio in his district, emphasizing their critical role in education and workforce development, which includes scientific and STEM fields. (U.S. Congressman Joaquin Castro, 2025-09)
Historical Legislative Action for Space Science Collaboration: In 2015, Representative Castro authored and passed an amendment allowing nonprofits, including the Southwest Research Institute in his district, to collaborate with NASA on orbital space debris research, demonstrating a past legislative initiative to expand scientific partnerships in space. (U.S. Congressman Joaquin Castro, 2015-05)
Challenges
Lack of Direct Committee Oversight: Representative Castro does not hold a seat on the House Science, Space, and Technology Committee, which may limit his direct engagement with NASA's specific programmatic and budgetary needs. (U.S. Congressman Joaquin Castro, 2025-01)
Competing Legislative Priorities: Representative Castro's public statements and legislative focus frequently highlight issues such as healthcare, education, immigration, and local infrastructure, which may lead to less emphasis on NASA science funding compared to these other priorities. (U.S. Congressman Joaquin Castro, 2024-06)
