Space is gooood.
The technology developer thus far to reach and use space has yielded numerous technologies that we now take for granted. Technologies that transform industries, save lives and allow us to live more comfortably. Simple things like cell phones rely on a complex network of satellites and earth-based stations, as does the GPS.
Satellites have been used for exploration of not only space, but the land and oceans too. Logging companies use them to determine the most efficient and least destructive method for cutting down trees for lumber. Various scientific organizations use them for studies in climate change, population studies and more, even ancient temples hidden under masses of foliage and soil have been found using space technology.
The list goes on and on. On the other hand, technology developed to explore the oceans has yielded little in the way of advancement. I suppose the fishfinder is a decent invention.
