In the emerging space economy, autonomous robotic missions with specialized goals such as mapping and mining are gaining traction, with agencies and enterprises increasingly investing resources. Mul-robot systems (MRS) research has provided many approaches to establish control and communication layers to facilitate collaboration from a technical perspective, such as granting more autonomy to heterogeneous robotic groups through auction-based mesh networks. However, since stakeholders are motivated by profit, they may have competing economic interests that prevent them from cooperating in a proprietary ecosystem. Related work suggests that distributed ledger technology (DLT) might serve as a mechanism for enterprises to coordinate workflows and trade services to explore space resources through a transparent, reliable, non-proprietary digital platform, yet others point to blockchain technical caveats reasons. We challenge this perspective by pointing to the core technical weaknesses of blockchains, in particular, increased energy consumption, low throughput, and full transparency through redundancy. We aim to advance the discussion in a direction where the benefits of DLT from an economic perspective are weighted against the drawbacks from a technical perspective. We finally present a possible DLT-driven heterogeneous MRS for map exploration to study the opportunities for economic collaboration and competitiveness and, therefore, boosting in situ resource utilization (ISRU) efficiency on the one hand and to develop solutions for the technical challenges of blockchains with latency sensitivity analyses, privacy-enhancing technologies, and scaling approaches on the other hand.
