Requires the Secretary of Homeland Security to treat space systems, services, and technology as a new critical infrastructure sector and to create a legal and organizational framework for that sector. It directs DHS to define terms, designate the sector, issue guidance, and report to Congress on implementation within short statutory deadlines.

The bill updates the Homeland Security Act to add the space sector, sets timelines for designation, guidance, and reporting, and gives DHS authority to organize risk‑management, information sharing, and coordination activities for space systems and related services.
