From page 18...
... NASA is planning to store all of the tools for the ISS in a centralized, ground-based storage area under the control of United Space Alliance. Efforts are also under way by EVA planners to develop standardized tools to reduce training time as ISS EVA training evolves from task-specific training (the mode of operation dunned ISS assembly)
From page 19...
... Virtual-reality training, a comprehensive form of asynchronous training, has proved to be a useful complement to underwater training and has the potential to enable more extensive on-orbit training protocols in the absence of the neutral buoyancy facility. The training ratio for Shuttle EVAs has historically been in the range of 10:1 (i.e., 10 hours 19 of neutral buoyancy training for each hour of actual EVA)
From page 20...
... , decreasing the payload weight required to replenish space suit consumables, extending operating life, and using microprocessors to control and monitor space suit systems. Payload weight required to replenish consumables might be reduced by regeneration of carbon dioxide absorbers, removing heat without evaporative water loss, decreasing oxygen leaks, and using advanced oxygen supplies.
From page 21...
... VISUAL INSPECTION AIDS Additions to robotic systems on the ISS that could relieve astronaut EVA requirements would also yield substantial benefits after Assembly Complete. One of the most significant robotic capabilities currently under development is an enhanced visual inspection system.
From page 22...
... Significant progress in robotics research promises to enhance the performance of robotic servicing systems through improved teleoperation modes and supervised-autonomous modes of operation for all of the planned or proposed robotic systems for the ISS. Two research and development programs, the Ranger Project and the Robonaut Project being developed by NASA Johnson Space Center, are sufficiently well developed and have a high enough probability of yielding significant improvements to the operation of the ISS post Assembly Complete to warrant serious consideration.
