Whatever the mission‚ be it manned or unmanned‚ for scientific research‚ applications or space transportation‚ a spacecraft must withstand the extreme stresses which occur during the launch phase‚ and once in orbit‚ the rigours of the space environment. There is one way of making sure of this: to test the spacecraft on Earth under conditions simulating‚ as closely as possible‚ those it will meet during the launch and its orbital life. This can be done with with tests which demonstrate by application
