Saving Data

One of the things I most definitely am is a data junkie. I like it raw, filtered, in charts...graphs, or even all over my screen at work. Data is what drives everything, and preserving it is even more important. One of the most important parts of energy modeling is having statistically significant data, and enough of it to have the mathematical support for your bayesian analysis. This little blurb though is just to show why you always preserve data, from NASA no less. Ok, IEEE did the work but NASA generated the data

The article focuses on the deceleration that occured in Pioneer 10 and 11 as they reached the outer solar system, subsequently befuddling scientists the world over for the last 30 years. IEEE has an article on how the pioneer data was looked at again by some people with thermal modeling expertise to explain, with some confidence, that the deceleration was due to excessive thermal radiation, about 60W total...or as the article says "about the same as the backward push your car experiences in reaction to the photons spit out by its high-beam headlights'
