DEUCES

The Duna Experimental Utility Craft for Exploration and Science (DEUCES) is an effort to design upper stages capable of reuse once in space. Inspired by Kerbal Space Academy and ULA's ACES upper stage, these autonomous stages are capable of placing a payload somewhere, and returning to a station for refuelling for another mission. To this end, we have established several DEUCES Reference Missions (DRM), allowing missions to be scoped more quickly and with higher reliability.
DRM #1: 1250m/s
  • Suborbital to LKO (low Kerbin orbit)
  • LKO to/from Mun or Minmus orbit
  • Mun orbit, landing, and return to orbit
  • LKO to Duna/Eve transfer (no reuse)
  • Land on Moho

DRM #2: 2000m/s, 700m/s return
  • ​Suborbital to KTO (kerbal synchronous orbit), deploying a payload, and returning the stage to LKO

DRM #3: 2500m/s
  • Suborbital to Mun or Minmus orbit
DRM #4: 2500m/s, 1250m/s return
  • Suborbital to Duna/Eve transfer, returning to LKO

​DRM #5: 700m/s, 700m/s return
  • LKO to KTO, returning to LKO after deployment.

DRM #6: 1250m/s, 1250m/s return
  • LKO to Duna/Eve transfer, returning to LKO

DRM #7: 2000m/s
  • LKO to Moho/Jool transfer (no reuse)

DRM #8: 2000m/s, 2000m/s return
  • LKO to Mojo/Jool transfer, returning to LKO
