Briefings

The Department of Transportation announced five proposed FAA rules to streamline Part 450 commercial space licensing, aiming to meet the White House's 1,000 launches target by 2030. Launched in September 2025, the SPACE Task Force coordinates policy changes, including consolidating safety documentation, allowing vehicle-sized hazard areas, and clarifying blast analysis scope. These proposals target existing Part 450 rules that were updated in March 2021, which previously caused complaints about delays. Public comments on the proposals will close on November 4, 2026.

Key points

• The SPACE Task Force, launched September 9, 2025, is an intradepartmental body coordinating space policy on behalf of the Department of Transportation to implement the White House's National Space Transportation Policy.
• The proposed Part 450 changes include exempting descending vehicles from lightning mitigation if they cannot leave a cleared area and clarifying that far-field blast analyses must cover existing locations, not hypothetical ones.

Context and limitations

Public comments on the proposed rules will close on November 4, 2026. The SPACE Task Force is an intradepartmental body, and the specific timeline for implementing the new rules remains unconfirmed.
