Addressing the Challenges  “What is the most politically acceptable, efficient, and cost effective approach to accessing excess launch capacity?”  No single approach meets every user needs  Steps could be taken to improve efficiency and cost effectiveness of rideshare  Need to reconcile lengthy gov’t launch planning timelines with smallsat timelines  Develop flexible, standardized interfaces and adapters (eg. EAGLE)  Fully utilize DoD Space Test Program to identify rideshare opportunities for all users −Should be on a regular and recurring basis −Make community aware of opportunities  Develop policy to enable commercial payloads to rideshare on gov’t launches  Implement contracting mechanism to procure commercial rideshare services 5 Welsch June2014
