Secondary Payload Adapters and Interfaces Technical Committee Report 17th Annual Small Payload Rideshare Symposium Johns Hopkins University/Applied Physics Lab June 10, 2015 This committee reviews existing and conceptual secondary adapters, the vehicles on which they can be flown, their capabilities and limitations, as well as potential flight opportunities. Secondary adapters’ shortfalls in weight or volume, limitations in vehicle compatibility, and other issues and perceived needs are to be identified and documented. Manifesting and scheduling issues will be evaluated and documented along with suggestions for resolution or improvements. Secondary Adapters Technical Committee • US Government policy • US Rideshare Options • Smallsat‐to‐Launch Vehicle Interfaces • Adapters and Dispensers – CubeSat dispensers and adapters – Small Sat adapters – Propulsive adapters Future Topics • Rideshare “Wiki Page” on SPRSA.ORG website • Hosted Payload Options • International Boosters/Rideshare Interfaces NOTE: Some of the documented hardware does not yet have flight heritage. The information provided here is a guide; please consult with the vendor.
