THE FUTURE ROLE OF DATA ARCHITECTURE IN SPACE EXPLORATION

摘要

Extending the presence of humans beyond earth orbit will require changes in the architectures employed to create, manage and use data. The earth-centric data architectures in place today must evolve to become integrated earth-space architectures that not only support the safety of the crew and accomplishment of mission milestones, but also support the inventiveness of human explorers and return the richer set of data that will be developed by their interaction with non-terrestrial worlds. Future space vehicles and outposts must become self-sufficient data processing centers participating within an earth-space based network of explorers, scientists, engineers and mission operators. Space-based data architectures must address the paradox of autonomous self-sufficient operations in conjunction with integrated collaboration; all within the constraints imposed by the distances and infrastructure of space based communications. The key to resolving this lies in moving beyond techniques such as indexing and key words for search, retrieval and synchronization of data, to taxonomy-based classification of data and content and to taxonomy-based discovery, replication and synchronization of data and content across earth-space data processing networks.
