Chapter 1 (part 2) Humans in Space

Learning Objectives

1. Identify key design implications for human missions vs. robotic spacecraft
2. Outline the mission design process

---

Human vs. Robotic Missions

· 2 basic design driver differences

o Astronauts are more flexible and adaptable than robots

o Astronauts need life support and additional safety precautions

---

The Design Process (Table 1-2 HSMAD)

· Define broad mission objectives

· Define mission requirements and constraints

· Develop alternate concepts and architectures

· Identify critical system drivers

· Select baseline mission

· Define systems requirements

· Document choices and rationale

· Iterate and Integrate the design

o Reassess Mission Statement, objectives and requirements

Life Cycle Analysis

• Various terminologies, same basic flow…
• Advanced studies / mission analysis
• Definition, design, develop, test, operate
• Phase A, B, C/D and E
• ‘Cradle-to-Grave’ Life cycle cost estimates
• R&D, DDT&E, manufacture, operate
• MTBF + FMEA = PRA
