1. A method of assembling a system to perform multi-stage cleaning of material from a space suit worn by an astronaut in a deep space environment, the method comprising:
installing one or more discharge units external to an interior volume of a facility in the deep space environment, each of the one or more discharge units configured to release one or more substances, wherein the one or more substances includes water or air and the interior volume of the facility is defined by an interior hatch that is separated from an exterior hatch leading to the deep space environment by an airlock; and
installing one or more collection units external to the interior volume, each collection unit being configured to trap released material that is released from a space suit based on the multi-stage cleaning to prevent the released material from entering the interior volume;
wherein the installing the one or more discharge units includes configuring the one or more discharge units to release air to blow off the material from the space suit or to release positively and negatively charged ions to neutralize the material on the space suit in a first stage of the multi-stage cleaning, to release water to clean off remaining material from the space suit in a second stage of the multi-stage cleaning, to release air to dry off the space suit in a third stage of the multi-stage cleaning, and to release wax to coat the space suit in a fourth stage of the multi-stage cleaning.
