A New Synthetic Hydrocarbon Liquid Lubricant for Space Applications
TL;DR: In this paper, synthetic hydrocarbon liquid lubricants based on polyalphaolefins have been developed for use in space applications and their physical properties have been fully characterized and their properties reported which include: kinematic and absolute viscosity, visco-ity index, vapor pressure, evaporation, specific gravity, pour point, coefficient of thermal expansion, refractive index, and flow activation energy.

Research on Liquid Lubricants for Space Mechanisms
TL;DR: In this article, four research areas at the NASA Glenn Research Center involving the tribology of space mechanisms are highlighted, including soluble boundary lubrication additives for perfluoropolyether liquid lubricants, a Pennzane dewetting phenomenon, the effect of ODC-free bearing cleaning processes on bearing lifetimes and the development of a new class of liquid lubricant based on silahydrocarbons.
