The main connection between technology and exploration is that technology makes exploration possible. At the same time, the desire to explore can help stimulate the creation of technology.
Over the years, the invention of new technology has typically helped bring about more exploration. The invention of the caravel, for example, made it much more possible for Europeans to explore in the Age of Exploration. The invention of things like guns and cannon that could be put on ships also allowed exploration to take place. In the more modern world, the invention of submersible technologies allowed exploration of the deep ocean to take place.
There are times when the desire to explore can help to stimulate the creation of technology. For example, the desire to get relatively cheap and reusable craft into space has led to the creation of new technologies for that purpose.
Overall, then, we can say that technology and exploration are closely connected. This is because technology is so necessary for many types of exploration.
