“…These mission types bring the possibility of greatly extended mission lifetimes and lower operational costs, but require a significant investment in on-orbit infrastructure to realize [35] . However, as a critical mass of space assets with servicing capabilities becomes prevalent, a unifying platform for requesting and exchanging services is necessary [36]. The integrity of service exchange for this application is of particular significance due to the potential for a servicing operation to inflict harm, either through software faults or intentional sabotage, during proximity operations.…”

Exponential growth of the space industry avails unprecedented opportunities to establish a marketplace of satellite infrastructure services. However, security and resource constraints pose critical challenges to implementing the exchange of services such as storage, compute or even arm-based manipulation. We propose a fully distributed architecture that will facilitate resilient, trustless interactions to enable space infrastructure as a service and applications such as in-space servicing. The distributed architecture engages Distributed Ledger Technology (DLT) such as blockchains and directed acyclic graphs to designate and enforce security policy via smart contracts between multiple parties across payloads owned or operated by different service providers on the same satellite bus or across a constellation. This work presents a zero-trust space infrastructure as a service architecture and examines how the architecture addresses critical challenges such as consensus and cyber resilience to facilitate a space services marketplace.

“…Space missions previously thought to be unaffordable and technologically impractical are no longer matters of science fiction. In-space servicing, assembly and manufacturing is one such type of mission segment that is expected to become commonplace in the coming decade that has a unique cyber risk profile [9]. Launch service provider diversification, also considered to be impractical from a financial standpoint, is not only viable, but a thriving marketplace.…”
