ABSTRACT:
NASA has many high-technology programs planned for the future, such as the space station, Mission to Planet Earth (a series of Earthobserving satellites), space telescopes, and planetary orbiters. These missions will involve advanced mechanical moving components, space mechanisms that will need wear protection and lubrication. The tribology practices used in space today are primarily based on a technology that is more than 20 years old. The question is, is this technology base good enough to meet the needs of these future longduration NASA missions? This paper examines NASA's future space missions, how mechanisms are currently lubricated, some of the mechanism and tribology challenges that may be encountered in future missions, and some potential solutions to these future challenges.
