Summary

Description

Access to space for Small Satellites is enabled by the use of excess launch capacity on existing launch vehicles. A range of sizes, form factors and masses need to be accommodated. An integration process that minimizes programmatic/technical risk to the primary, allows "late flow" integration and predictable cost/schedule for the secondary enables regular and cost-effective access. The integration process proceeds smoothly when the right adapters accommodates the secondary in a seamless way. Design_Net has developed and flown a RideShare Adapter (RSA) for FALCON class vehicles that meets these requirements. We are currently working with United Launch Alliance (ULA) for a broader class of rideshare accommodations, upgrades to capability of the ESPA and development of interfaces that allow late access. Based on this experience Design_Net will continue, via this SBIR, to develop appropriate adapters for other types of secondary payloads on other launch vehicles. Phase 1 will see preliminary design of another adapter for intermediate size small sats (larger than "cubesats" but smaller than ESPA) for a selected launch vehicle. During Phase 2 we will develop and qualify the selected adapter design to TRL 8.
