Results of Application Demonstration of Autonomous Offshore Power System Supporting Multiple Mobile and Static Assets

Over the last decade, several technology trends have dominated the innovation cycle within the terrestrial economy. Electrification, cloud computing, decarbonization, digitization, and autonomy are representative examples of macro trends that have had a rapid and fundamental impact; an impact felt not only in user-facing technologies, such as electric vehicles and software-as-a-service, but also in the infrastructure required to deliver those technologies. However, the scale of the impact and rollout has not been felt equally between the terrestrial and ocean economies. Here, the innovation cycle in the ocean economy is significantly slower. What accounts for the difference and are there solutions to this issue?

Enabling the Electrification of Offshore Activities – Co-Demonstration of Next-Generation Autonomous Offshore Power System and Resident, Uncrewed Mobile and Static Assets at PacWave Wave Energy Test Site

Oceans cover two-thirds of the earth's surface and form the world's biggest and best – yet largely untapped – battery. Ocean waves have more energy density than other renewables, including wind, solar, and biomass, and have the potential to supply 4x the world's annual energy consumption (Masterson, 2022; Zic, 2020). In addition to the impact wave energy can have on decarbonizing and diversifying the electric grid, it offers a significant value proposition in the emerging blue economy sector (LiVecchi et al, 2019). The blue economy consists of industries operating offshore, including shipping, oil and gas, defense and security, aquaculture, and research. These industries require bringing people and energy on site to perform daily work, but current energy costs in the blue economy are extremely high. Here, the prevailing processes are complex, including shore dependencies and fuel transportation logistics. Few alternatives for reliable power generation exist, with the most prominent being high cost and high carbon emissions diesel generation. Because of this lack of affordable, reliable power, the trends of electrification, digitization, and automation that have led to substantial innovation and improvements in the terrestrial economy over the last two decades are slow to come to the blue economy.

Preparing for the 90s using today's communications assets

Such existing NASA/U.S. facilities and spacecraft as those of the Deep Space Network, VLA, and Arecibo are presently judged capable, at modest additional investment during the next five years, to acquire unique space science data, to generate mission planning data for missions to be launched in the early 1990s, and to evaluate and demonstrate communications and navigation technology for missions of the late 1990s and beyond. The more ambitious of these efforts will contribute the continuation of space research attractiveness for students, as well as furnish an important part of their scientific training.

Graphical programming: A systems approach for telerobotic servicing of space assets

Satellite servicing is in many ways analogous to subsea robotic servicing in the late 1970's. A cost effective, reliable, telerobotic capability had to be demonstrated before the oil companies invested money in deep water robot serviceable production facilities. In the same sense, aeronautic engineers will not design satellites for telerobotic servicing until such a quantifiable capability has been demonstrated. New space servicing systems will be markedly different than existing space robot systems. Past space manipulator systems, including the Space Shuttle's robot arm, have used master/slave technologies with poor fidelity, slow operating speeds and most importantly, in-orbit human operators. In contrast, new systems will be capable of precision operations, conducted at higher rates of speed, and be commanded via ground-control communication links. Challenge presented by this environment include achieving a mandated level of robustness and dependability, radiation hardening, minimum weight and power consumption, and a system which accommodates the inherent communication delay between the ground station and the satellite. There is also a need for a user interface which is easy to use, ensures collision free motions, and is capable of adjusting to an unknown workcell (for repair operations the condition of the satellite may not be known in advance). This paper describes the novel technologies required to deliver such a capability.

Research and Development, Technology Requirements, and Use of Existing Space Assets

Technology requirements are addressed in three categories: (1) Passenger-carrying STS(s); (2) orbital facilities (including on-orbit operations such as servicing) and human factors (crew and passenger training and recreation, on-orbit environmental control, etc.); and (3) ground infrastructure. An example tourism trip scenario is used in discussing possible targets for technology development activities. Some general comments are made as are considerations for other working groups.

Microgravity Research, An Agency-Wide Asset: Using NASA-Generated Knowledge to Solve its Own Problems

The National Center for Microgravity Research (NCMR) is a vital and successful operation, effectively supporting NASA's program in many ways beyond technical monitoring. NCMR is supplying leadership for certain new initiatives important to NASA's future. NASA might regard NCMR as kind of a small laboratory of innovative research management, and should support it generously.
