Space National Guard Establishment Act of 2024

This bill establishes a Space National Guard as part of the organized militia in states, territories, Puerto Rico, and the District of Columbia where the Space Force operates, and creates a Space National Guard of the United States as the Space Force's reserve component. It defines key terms for these entities in federal law (including requirements for training, federal recognition, and status as a space force), mandates implementation by the Air Force and National Guard Bureau within one year, and requires annual congressional briefings on operations and funding. The bill explicitly states it does not affect existing military installations or require facility relocations.
