what motives people to explorer?

Answer 1

When Edmund Hillary (who was the first to climb Everest along with Sherpa Tensing) was asked why he wanted to get to the top of Everest he replied, "Because it's there".
I think the urge is in all lively minded people just to go somewhere we have never been before.

Answer 2

The poet Kipling asked this question 100 years ago. He imagined himself a wife of a Viking pirate in springtime, asking her man who was about to cross the cold North Sea in search of plunder:

"What is a woman that you forsake her,
And the hearth fire and the home acre,
To go with the old grey widow-maker?"

Most humans have a relentless curiosity. As Walt Whitman, I think it was, put it:
"We sing the restless discontent
That leaps from star to star."
It is a desire to know, a desire born in all of us because the Unconquerable Soul knows everything, and the mind thinks that it can find out by the intellect and the senses. Our minds were made that way, it is one of the basic givens that have enabled humans to succeed as a species, our ability to solve problems by logical left-brain thought and imaginative right-brain creativity. Every tiny tot that was ever born starts life by exploring the world s/he has just come into, touching this, dropping that, pushing the other, pulling it to see if it comes apart.

So I figure the short answer to your Q is "the desire to satisfy our unfulfilled desires".
