SUBSEA will use prototype information technologies that will be evaluated and iterated upon based on their ability to support science-driven LLT operations. Science investigations conducted in LLT will require mission operations software tailored to the unique use cases and requirements that will arise. The LLT mission architecture is a significant departure from current planetary rover operations (MER, MSL). Our goals are to identify software capability requirements in support of mission concepts involving long communication latencies between distributed Science Teams (dST) on Earth and LLT support crews in deep space, and to mature our current software capabilities as candidate technologies for LLT missions. We will achieve this by integrating our Exploration Ground Data Systems (xGDS) software with Nautilus telepresence mission support systems, and then systematically evaluating the technology during our SUBSEA field campaigns. xGDS will provide human/robotic software functionality to support integration and visualization of diverse data products relevant to future human exploration of deep space.
