Plymouth Rock: An Early Human Asteroid Mission Using Orion

Initial Feasibility Assessment
• Two Orions together provide just enough
habitable volume for two astronauts
• Dual Orions can accommodate additional food,
water, and oxygen needed for two people on 180
day missions within volume and mass limits
– The crewed Orion launch is mass constrained by launch
performance and the capability of the launch abort
system and recovery system. Therefore, most of the
additional consumables are launched in the
supplemental Orion
– Consumables are budgeted and allocated to support an
emergency return using either Orion alone
– Waste and trash management are a challenge
