Data from sensor bearing satellites requires processing aboard terrestrial data centers that use water for cooling at the expense of high data transfer latency. The reliance of terrestrial data centers on water increases their water footprint and limits the availability of water for other applications. Therefore, data centers with low data transfer latency and reduced reliance on earth’s water resources are required. This paper proposes space habitat data centers (SHDCs) with low latency data transfer and that use asteroid water to address these challenges. The paper investigates the feasibility of accessing asteroid water and the reduction in computing platform access latency. Results show that the mean asteroid water access period is 319.39 days. The use of SHDCs instead of non-space computing platforms reduces access latency and increases accessible computing resources by (11.9% – 33.6%) and (46.7% – 77%) on average respectively.

“…The habitat, as shown in the International Space Station based concept 4 in Figure 3, is an example of a complex system needed to fulfill deep space requirements. Its usage in long duration flights far from Earth will necessitate the crew interacting with many software driven subsystems, including communications, guidance and navigation, propulsion, and life support.…”

Long duration and complex mission scenarios are characteristics of NASA's human exploration of Mars, and will provide unprecedented challenges. Systems reliability and safety will become increasingly demanding and management of uncertainty will be increasingly important. NASA's current pioneering strategy recognizes and relies upon assurance of crew and asset safety. In this regard, flexibility to develop and innovate in the emergence of new design environments and methodologies, encompassing modeling of complex systems, is essential to meet the challenges.

“…Various deep space habitat concepts are under evaluation with pressurized volumes up to 662 m 3 providing nearly 130 m 3 of habitable volume per CM. 25 The smaller pressurized volume is the more challenging from an LSS development perspective relative to system packaging and dynamic response times and serves as the basis for development.…”
