Why graphite is a better lubricant on moon than earth?

Question:-
Why graphite is a better lubricant on moon than earth?
Answer:-
Graphite and graphite powder are valued in industrial applications for its self-lubricating and dry lubricating properties. There is a common belief that graphite's lubricating properties are solely due to the loose interlamellar coupling between sheets in the structure. However, it has been shown that in a vacuum environment (such as in technologies for use in space), graphite is a very poor lubricant. This observation led to the discovery that the lubrication is due to the presence of fluids between the layers, such as air and water, which are naturally adsorbed from the environment. This molecular property is unlike other layered, dry lubricants such as molybdenum disulfide.
Hey!!!
Graphite is a better lubricant on moon because there is no gravitational pull and it is easy for graphite to act as a lubricant.
