Test
Qualification
tests demonstrate design suitability
of the spacecraft hardware and software.
Component Qualification
Qualification
hardware
is a set of components built exclusively for qualification
testing. This hardware is used to build the qualification
spacecraft that is also tested at qualification
levels.
Flight
hardware
first off the production line is tested at qualification
levels then assembled into the proto-flight spacecraft,
which is also tested at qualification levels before
launch.
Vibration
occurs during launch from launch vehicle acoustics
and engine resonance coupled through payload mounts.
Shock
comes from pyrotechnic explosions that separate
stages, jettison aerodynamic fairings and deploy
solar arrays, antenna or sensor appendages.
Thermal
vacuum
is the environment of space. Vehicle rotation and
planetary shading set the spacecraft's thermal cycle
of heating and cooling.
Electromagnetic
compatibility
(EMC) tests check for interference between electrical
and electronic components that could degrade performance.
