Insect wings may have begun to evolve as lateral extensions of the body that were used as heat dissipaters for thermoregulation.
Mariulka [41]

Exaptation

Explanation:

In this example, the lateral extensions that developed were meant for thermoregulation.

But these became sufficiently large to support gliding through the air and later on were used for flight.

Thus the structure assumed a function for which it was not meant and its original function shifted to a completely different dimension giving rise to modern insect wings. So we can say that this is an example of Exaptation.

Answer:

There are many reasons why manned space probes to Saturn are simply  unachievable. Getting to space is incredibly hard. The force of gravity is very hard to escape.

Second, we simply don’t have the technology to make it that far with a manned probe. Saturn is more than a billion miles away. It would take more than several years to go that far. To keep astronauts alive, entertained, and sustained is also a big challenge. In conclusion these are some reasons why a manned space probe to Saturn is unachieveable.
