Space agencies worldwide have a long-term vision of sending human-crewed missions to Mars. The next favorable launch window is in 2033, and planning is underway to make such ventures a reality. A crucial part of these preparations is the search for new technologies to reduce the risks of the missions. One technological advance critical to this end is battery-less wireless sensor technology, as used in the Internet of Things (IoT), which can be used advantageously to continuously monitor the physiological condition of crewmembers in the space habitat and the structural health of space equipment. State-of-the-art battery-less wireless sensors are not yet suitable for operation in the space environment; key reliability issues remain to be addressed. These challenges include scarce power resources due to battery-less sensor operation, which is also a problem on Earth. The talk will review existing work on battery-less wireless sensors for reliable operation at ultra-low power consumption, focusing on batteryless wireless sensors using ultra-high-frequency radio frequency identification technology.

Digital Twins: Advancing Engineering in Space and Extreme Environments
Building systems for operation in extreme environments is a challenging proposition. This talk will present an aspirational, strategic vision for how digital twin technology can significantly advance the design, engineering, and operation of complex systems in extreme environments.
A reasonable characterization of an extreme environment is an environment which presents challenges, difficulties or obstacles to the presence of humans or the objects or systems we engineer, build, install, and operate in those environments. From the depths of our oceanic trenches to upper atmospheres and outer space, extreme environments are particularly unforgiving: systems are more susceptible to damage and wear and tear, and their failures are often catastrophic. Exacerbating the problem is the reality that access to these environments is quite challenging, making monitoring, maintenance, and repair of systems far more difficult, less practical, and less feasible than in more hospitable environments.
Making systems more reliable for extreme environments is an important goal. Greater reliability means an increased probability of continuous, correct operation and the mitigation of the risk of failures. Digital twin technology can bring efficacy to, and reduce the risk of, designing, building, and operating complex systems in extreme environments—making systems in extreme environments more reliable. Moreover this technology space holds promise to be able to advance the ability to anticipate failures and perform preventive maintenance, avoiding serious failures and reducing costs.
There is an intrinsically close relationship between digital twin technology and the Internet of Things (IoT). The intelligence and models built into digital twins can reduce the dependence on, and risk of, large numbers of expensive, specialized or custom sensors, while maintaining or even improving the ability to monitor the state of remote systems. The promise is for improvements in the ability of an entity’s digital twin to anticipate failures and perform preventive maintenance or preemptive self-healing prior to a failure. This becomes increasingly important for faraway systems in extreme environments that are not practically accessible.
Finally, this talk will discuss the oft-ignored or misunderstood crux of the digital twin value proposition: enablement of interoperability, automation, reduced risk of human error, and concomitant cost reductions across companies and enterprises, industries, academia, industry, government. Digital twins will further bring value by improving supply chains, procurement, governance, compliance, and many other aspects of coordination and cooperation across large entities participating in large industrial R&D and manufacturing.
