20 Cygnus System Facilitates Exploration Goals

 Affordability - Evolutionary approach with utilization of existing space qualified systems and cargo missions to ISS, provides lower cost under tightening budget constraints

 Early Schedule - Utilization of existing capability provides opportunity for near-term mission support. Potential to “piggy-back” on currently planned CRS missions (8 missions through 2016)

 Maturity / Reliability - Cygnus heritage and redundancy provides reliability

 Technology Advancement - Cygnus utilization provides new technology risk reduction in flight environments

 Flexibility - Cygnus system elements are adaptable to evolving mission needs, goals and requirements

 Partnership - Involvement of Cygnus concepts in NASA Exploration assessments promotes commercial / NASA / international partnership
