Science = false will turn off FeatureScience and disable all science related patches: hard drives, experiments, background transmission. DataRateDampingExponent essentially controls how fast the data rate drops with distance. Realistically, for real solar system scales, you would use 2 here. But the KSP stock sytem is much, much smaller (I think Jool is approximately as far removed from Kerbol as Mercury is from our Sun) so the standard value gives data rates that are too high for what I'd
