Space Policy Directive-1

“Lead an innovative and sustainable program of

exploration with commercial and international partners to

enable human expansion across the solar system and to

bring back to Earth new knowledge and opportunities.

Beginning with missions beyond low-Earth orbit, the

United States will lead the return of humans to the Moon

for long-term exploration and utilization, followed by

human missions to Mars and other destinations.”
