2 Spacecraft: Components to Subsystems Architectures choices for spacecraft have remained fairly constant for decades 2

3 Satlets: Rethinking The Spacecraft Satlets : satellite architecture components into which the functional capabilities of a conventional spacecraft are decomposed and can then be aggregated back together to provide desired subsystem capabilities Pareto-optimal satlet architectures that satisfied mission requirements while maximizing expected profit were investigated during Phase 1 of the DARPA Phoenix program and found solutions with fewer building blocks than typical 3

4 A New Satellite Morphology Using a biological cell approach to the development of satlets yielded the HISat (Hyper-Integrated Satlet), a stem-cell like system cell HISat is a single satellite architecture component into which all the functional capabilities of a spacecraft are provided at a basic hardware level and differentiated and aggregated by software 4

5 HISats as the Basic Building Block NovaWurks has successfully developed HISat prototypes for the DARPA Phoenix program. By reassembling a sufficient amount of HISats and payloads, a spacecraft with or the required capabilities can be formed by aggregation of resources 5

6 Accommodating Specialized Devices/Payloads User Defined Adapter (UDA) programmable space ready support system allows for flexible and rapid integration Provides for power, data, and thermal management Payload accommodation capability scales easily with multiple UDAs UDA Payload HISats 6

7 Accommodating Very Large Structures The HIMast provides for a variable deployment length boom (>4m) overall reach to meet a wide range of long reach or large structure requirements Embedded power and data lines Utilizes intrinsic HISat capabilities Multiple HIMasts/HISats easily configured for 2D and 3D structures 7

8 Accommodating Fine Position Control Articulated Positioners (APs) provide optical precision position and control Embedded thermal management system maintains critical optics APs have power, data, and fuel system connectivity Phoenix Phase 1 demonstrated capabilities 8

9 PAC (Pack of Aggregated Cells) Design Flexibility One of the benefits of a cellular architecture is its flexibility throughout its lifecycle The inherent flexibility during the design phase has already been found very useful with over 83 different flight configurations for 11 missions investigated over a matter of months.

10 Conclusions Rapid design flow for various missions and multiple configurations became the norm during the course of Phoenix Phase 1 Cellular architecture issues and challenges were identified, investigated in depth, and demonstrated to have practical solutions. As a result, a new paradigm for space has been established. Through the means of HISats and the appropriate toolset of variants, low-cost rapidly configurable space systems of any size are becoming possible. And we can dare to dream, no design and build, in a manner not possible before The authors thank the DARPA Phoenix Advanced Technologies Program for funding the research presented here and wish to acknowledge the contributions of Roccor and Altius in providing support for HIMast.
