In my last few blogs we have had an underlying principle which is the high reliability required for space applications. We've looked at the different sources of radiation and discussed in length the different types of radiation tests including SEE and TID testing. We looked at how temperature extremes can occur in a space application. In the last blog we looked at different space mission lifetimes from a sampling of NASA missions over the last 30 years or so. Specifically, when you look at the long mission lifetimes you can start to see why there is a lot of screening performed on a product. When you place a device into space for 10, 15, even 20 years or longer then it is imperative to know before it is ever launched that it can withstand the rigors of the environment. As I've mentioned before there pretty much isn't a replacement plan if a component fails. There are exceptions like the Hubble Telescope where work has been performed to correct issues after it was launched, but that is definitely not the norm. For something that is flying to Jupiter such as the Juno probe, there isn't a way to replace any defective parts after launch. So let's take a closer look at the screenings where in this installment I discuss the various screenings steps for ADI's standard space product offerings. As you can see from the table there are quite a few steps performed in order to ensure the reliability is sufficient for operating in space.
