A SUGGESTION
DAVE BYERS
2011/3/22

2. O STRATEGIC RESOURCES TO ACADEME &
SCOPE
O STRATEGIC RESOURCES TO ACADEME &
GOVERNMENT ASSUMED/NOT CONSIDERED
- PROVIDE UNIQUE/CRITICAL VALUES
O TECHNOLOGY DEVELOPMENTS/INSERTIONS
- SINGLE SUGGESTION ON PRIORITIZATION

3. BACKGROUND O NASA BUDGET (Policy) NEGOTIATIONS DOMINATE
- MAJOR ECONOMIC/EXTERNAL CONSIDERATIONS
DOMINATE
- TECHNICAL CONSIDERATIONS ≤ SECONDARY
- NEAR-TERM OFTEN EMPHASIZED -

4. A SUGGESTION O STRONGLY PRIORITIZE ISP RESPONSIVE
TO MULTI-SECTOR DRIVERS
- ENHANCE COMPETITIVENESS & CAPABILITIES
O & WITH MULTI-MISSION BENEFITS

5. Q & A O CAN ISP CREDIBLY/SIGNIFICANTLY AFFECT
MULTI-SECTOR ISSUES & DRIVERS?
O YES! BECAUSE:
- HUGE PENALTY FOR NEARLY ALL HIGH-VALUE MISSIONS
- OPTIMUM MISSION COSTS ACHIEVED VIA LOW-COST
LAUNCH & HIGH PERFORMANCE ISP
- CREDIBLE TECHNICAL OPTIONS EXIST

6. SUGGESTED ISP PRIORITIES
O ISP TECHNOLOGY/SYSTEMS THAT SIGNIFICANTLY
INCREASE/ENABLE USA:
- LAUNCHER MARKET CAPTURES/RELEVANCES
- USA COMSAT BID COMPETITIVENESS
- NEW BIZ VENTURES (S/C REFURB, DEBRIS, SMALLSAT, ?)
- USA FULL RLV & DUAL-LAUNCH PRACTICALITY(?)
O AND ARE RELEVANT/EVOLVABLE TO:
- NASA ROBOTIC & EXPLORATION MISSIONS
O INCLUSIVE ANALYSES TO DEFINE & VALIDATE THE ABOVE

7. A RIDER O ASSURE ALL VALIDATIONS REQUIRED FOR ACCEPTANCES & INSERTIONS
- KEY PLAYER INVOLVEMENT CRITICAL
- INTERFACE & NON-PROPULSION ISSUES
- DON’T START IF FINISH IS UNREALISTIC

8. CONCLUSION O AN ISP INVESTMENT PRIORITY SUGGESTED THAT OFFERS NASA:
- BROADENED CRITICAL RELEVANCES
- MIMINIZED RISK & RESOURCE EXPOSURES
- GREATLY INCREASE EXPECTATIONS FOR VALUES
