Cubesats equipped with ion thrusters, could change how we explore space

These tiny satellites, equipped with ion thrusters, could change how we explore space

Any advancements that could reduce operating costs are worth investigation. Money seems to be the limiting factor so many times.

How close is the nearest star. If our sun was a grain of sand alpha centari is 4 miles away. The earth is 1.5 million times times smaller than the sun. So imagine how small we are. The distance is huge.

Then I think about how small an atom is or trilobite or nano technology we develop

Then, we see a photo like "Hubble's Ultra Deep Field" and we realize again how insignificant we are. I find that reassuring.
