The participants of the SIECA program report to NASA's Goddard Space Flight Center where they fulfill their internship requirements. Research opportunities exist in the areas of science, engineering and mathematics.

Each student works with a mentor from GSFC and has the opportunity to use many of the facilities available at the center. First year participants are often invited back for second year experiences. Last year's participants worked in the following divisions of GSFC:

• Assurance Management Office, (Code 303) — responsible for supporting the implementation of mission assurance over the entire program life cycle for all GSFC, Greenbelt, Space Flight, and Space Flight Support Missions.
• Flight Programs & Projects Business Management Office, (Code 403) — responsible for planning and directing development, implantation, and administration of resources management for there division.
• Heliophysics Projects Divsion, (Code 460) — responsible for the management, coordination, and implementation of heliophysics missions in support of the NASA Headquarters Science Missions Directorate.The goal of the HPD is to understand our changing Sun and its effects on the Solar System, life and society.
• Mechanical Systems Division , (Code 540) — responsible for the design, fabrication, integration, and testing of advanced scientific instruments.
• Instrument Systems and Technology Division, (Code 550) — responsible for providing instrument-engineering expertise to enable advanced state-of-the-art Earth and Space science missions. 
• Electrical Engineering Division, (Code 560) — responsible for the leadership and vision associated with flight electrical / information systems and technologies.
• Information Systems Divisions , (Code 580) — responsible for providing mission information systems and system components, and expertise in all phases of robotic mission implementation.
• Mission Engineering & Systems Analysis Division, (Code 590) — responsible for end-to-end system engineering and analysis for new and existing space missions, done either in the “in house” or “out house” mode.
• Administrator and Resources Management Office, (Code 603) — responsible for the resources of Exploration Sciences.
• Astrophysics Science Division, (Code 660) — responsible for supporting the GSFC astrophysics projects by providing scientific leadership and supports a research program to achieve NASA’s strategic science goals.
• Heliophysics Science Division , (Code 670) — responsible for exploring the solar atmosphere and its interactions with the Earth, responsible for exploring leading the conception and development of solar and space physics missions, communicating science progress to the public, and inspiring the next generation of scientists.
• Solar System Exploration Division, (Code 690) — responsible for planning, organizing, evaluating, and implementing a broad program of scientific research, both theoretical and experimental, to explore the solar system and to study the formation and evolution of planetary systems.
