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.”

load byremoving system mass from PPE. Likely
implementation 12kW-hrs total (Tw o 6kWh at 60%
