Testing
Spacecraft propulsion systems are often first statically tested on the Earth's surface, within the atmosphere but many systems require a vacuum chamber to test fully. Rockets are usually tested at a rocket engine test facility well away from habitation and other buildings for safety reasons. Ion drives are far less dangerous and require much less stringent safety, usually only a large-ish vacuum chamber is needed.
Famous static test locations can be found at Rocket Ground Test Facilities
Some systems cannot be adequately tested on the ground and test launches may be employed at a Rocket Launch Site.
