There is a need to develop accelerated life test techniques and scale factors that people can believe in. Space Station Need improved bearings, lubricants and gears. Type is dependent on application. Manned missions to Mars. Need improved bearings, lubricants and gears.
Type is dependent on the application.
Shuttle flights to space station. Cryogenic propulsion issues. Technology barriers for future space drive systems Qualification testing methodologies inadequate. Significant technology milestones we should strive for. Improved accelerated life testing techniques.
