RES meaning in Space Science ?

Answer: What is Reservoir mean?

A reservoir (; from French réservoir [ʁezɛʁvwaʁ]) is most commonly an enlarged natural or artificial lake created using a dam to store fresh water.

Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees.

Defined as a storage space for fluids, reservoirs may hold water or gasses, including hydrocarbons. Tank reservoirs store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum, below ground.
