Everyone in the space industry is very much aware of the data-corrupting consequences of radiation in deep space, and will only use radiation-hard components for space missions.
On scientific missions to deep space a wealth of data is gathered, analyzed and compressed on-board before being relayed back to earth. The data cannot be sent to earth in its entirety since modern instruments gather much more data than can be communicated back to earth. For a correct interpretation of what is going on in space, and valid answers to exciting questions it is key that the compressed and processed data is correct.
Unfortunately, reliably processing and compressing of data might be easier said than done, as the only existing European digital signal processor (DSP) for space is obsolete: it provides less than 6% of the 1000 MFLOPS performance expected today. European space missions currently rely on a combination of FPGAs and commercial off-the-shelf (COTS) components, with the drawbacks of limited reliability and significant extra mass, complexity, and power consumption.
With the planning for the Cosmic Vision programme in mind, ESA plans to have a standard ASIC with a space qualified rad-hard Digital Signal Processor and a performance of at least 1000 MFLOPS in its portfolio.
