What satellites help to show us is we've actually only found a fraction of a percent of ancient settlements and sites all over the world... It's the most exciting time in history to be an archaeologist.

Scientists use satellites to track weather, map ice sheet melting, detect diseases, show ecosystem change... the list goes on and on. I think nearly every scientific field benefits or could benefit from satellite imagery analysis.

Archaeologists use datasets from NASA and commercial satellites, processing the information using various off-the-shelf computer programs. These datasets allow us to see beyond the visible part of the light spectrum into the near, middle, and far infrared.

From a good lie in the middle of a fairway bunker, I'll make the same swing as I do from an average fairway lie. I'll dig my feet in slightly and keep my lower body stable so I won't slip, but I don't change my club selection or setup. It's only when the ball is sitting down in the sand that I'll make some modifications.
