Atlas for Human Spaceflight 15 Feb 2006 5 Atlas Program Evolution Approach
•Atlas evolution elements become fleet baseline
•Atlas evolution benefits existing customer base – Maintain/improve Atlas 401 cost/launch • Phase 1 Centaur (SEC) cost Centaur III cost • Phase 2 Booster cost Atlas V booster cost – Improve cost at 5XY and HLV performance levels – Accommodate NASA Space Exploration and NRO growth requirements • Both super heavy lift and CEV requirements
•Maximize DoD/NASA/ Commercial synergy – Common element architecture – Enable NASA/ DoD sharing of investment
•Credible, sustainable program – Time phased to meet NASA affordability – Minimize use of new or risky technology, minimize complexity • No new engines required for baseline evolution • No cross feed, limit clusters to five-body
•Existing LC-41 infrastructure through Phase 2 development
•Current and evolved mission reliability and safety supports human rating – Inherent design reliability, demonstrated reliability through commonality

Atlas for Human Spaceflight 15 Feb 2006 10 Atlas Design Philosophy Overview • Common elements –Commonality driven down to part level
• Flexibility, wide range of missions & capabilities
• Simplicity, fault elimination –Reduced part counts –Fewer stages, fewer engines, fewer sep. events
• Fault tolerance, high reliability –Eliminate single point failures
• Rigorous margins & testing –Comprehensive, test like you fly –Analysis anchored to test & flight data
