The Space Infrastructure Act mandates the Secretary of Homeland Security to officially recognize space systems, services, and technology as a critical infrastructure sector within 30 days of the bill's enactment. This designation aims to enhance the security and resilience of vital space-related assets and operations. Within 180 days, the Secretary must issue comprehensive guidance, defining the sector's scope to include satellites, terrestrial systems, and launch infrastructure, and designating a Sector-Specific Agency . This guidance will also identify appropriate Government Coordinating Councils and Sector Coordinating Councils to support the sector's security efforts. Finally, the bill requires a report to Congress on the guidance's implementation and formally amends the Homeland Security Act of 2002 to include space systems as a critical infrastructure sector.
