    Abstract
    The tools, technologies, practices, policies, procedures and procurement process developed and implemented over 50 years to produce highly reliable spacecraft and spacecraft subsystem equipment have yielded spacecraft and launch vehicles whose reliability is dominated by premature equipment failures and surprise equipment failures at yearly rates as high as 25% that increase risk and decrease safety, mission assurance and effectiveness. Large, complex aerospace systems such as aircraft, launch vehicle and satellites are subjected to most exhaustive and comprehensive acceptance-testing program at the factory that is also used in other industries and that also suffer from the high premature failure rates. Desired/required spacecraft equipment performance is measured confirmed during factory testing, however equipment usable/mission life requirement is not measured but calculated manually and so the spacecraft and launch vehicle equipment that will fail prematurely are not identified and replaced before use. Spacecraft equipment mission-life is calculated using stochastic equations from probability reliability analysis engineering standards such as MIL STD 217. The change in the engineering practices used to manufacture and test spacecraft to identify the equipment that will fail prematurely include using a prognostic and health management (PHM) program. The PHM includes using predictive algorithms to convert equipment analog telemetry of any type into a measurement of equipment usable life by demodulating the telemetry behavior in time, amplitude, frequency and phase. The conversion of equipment analog telemetry from performance data to a measurement of usable life is done in a prognostic analysis. A prognostic analysis includes an engineering analysis that is shared with manufacturing and test, but results in premature equipment failures at rates as high as 70% once the equipment gets to space in space, but also includes a scientific analysis of the analog telemetry so that conjecture and speculation is not used to identify the presence as systemic noise.

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
