  1. Alternatives Concepts White PaperIPT 02E Team Eclipse

  2. Project Management

  3. Overview • Phase 2 • Seek to establishes team roles • Develop two alternative designs • Select one design as the final concept to take into Phase 3. • Design Concepts • Viking Lander, the baseline design • Lander on Wheels (LOW), final design chosen • Lander + Rover

  4. Technical Description • Overview of Phase 2: • Deliverable Items: • White Paper • Summarizes the strategy for selecting alternative systems • Qualitative/quantitative information to evaluate each idea • Logical rational for down selecting one concept among the three concepts • Oral Presentation • Summarizing information from the White Paper to present to the review board.

  5. Technical Description • Specification Summary • Level 1 Requirements • Housed within an Atlas V-401 EPF Shroud • Total Landed Mass – 997.4 kg • Launch Date – NLT September 30, 2012 • Survivability Time of 1 Year • Attain a slope of 12º • Polar Landing as well as other Lunar Landings • Land Precision +/- 100m 3σ • Maneuverability • SMD to ESMD

  6. Team Eclipse Approach to Phase 2

  7. Description of Concepts • 3 Concepts • Viking Lander (Baseline Design) • Lander on Wheels (Concept 1) • Lander + Rover (Concept 2) • Selection Process • Advantages and Disadvantages • Weighting of FOMs • Analysis and Comparison • Concept Chosen: Lander on Wheels (Concept 1)
