Degradation of these thermo-optical properties can cause an undesirable change in temperature of the spacecraft or its components. Loss of transmittance through solar cell coverglass materials, such as by contamination, can result in decreased output of solar arrays and thus a reduction in overall spacecraft power.

Delta-v - Wikipedia

en.wikipedia.org/wiki/Delta-v

Delta-v (literally "change in velocity"), symbolised as ∆v and pronounced delta-vee, as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launch from, or landing on a planet or moon, or in-space orbital maneuver. It is a scalar that has the units of speed.

Hall-effect thruster - Wikipedia

en.wikipedia.org/wiki/Hall-effect_thruster

In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume.Hall-effect thrusters (based on the discovery ...
