A "White Room"—also called a "clean room"—is a highly clean enclosed area where satellites and rocket parts are assembled and tested prior to launching. White rooms provide the necessary controlled environment to ensure that a satellite is ready for launch. Instruments onboard satellites are very sensitive to dust and degrade when exposed to oil or humidity, so a White Room maintains a constant temperature and humidity, eliminates dust, and protects the satellite during its development, construction, and testing.

Typically, White Rooms are also designed to guard against electromagnetic hazards. For example, the floor of a White Room might be constructed to avoid a buildup of static electricity. These precautions ensure that electronic and electrical testing of electrical systems...
