Abstract

Space Lubricants In article number 2110429, Aurélien Saulot, Tobin Filleter, Guillaume Colas, and co-workers engineer a high-performance space lubricant for the extreme environments faced by spacecrafts. The co-deposition of MoS2 with tantalum produces a synergistic effect where the tantalum preferentially oxidizes in terrestrial environments and enhances lubrication in deep space vacuum, resulting in low friction and wear despite the harsh conditions seen by spacecrafts.
