Absolutely astounding!

I guess that star never asks the question "are we there yet?" :) (ignoring the actuality of relativity and space/time for a second)

And ignoring the actuality of traveling in a circle!

Simply amazing that they are able to gain/interpret that type of data. From the earth to the moon in less than 2 min. Wow!
