Reading about this always makes me remember how much we stand at the shoulders of giants.

Thinking about things like on each of those voyages half the crew will die of Scurvy and other illnesses, for hundreds of years.

Now it is going to the moon or Venus, or Mars what requires a significant risk to do, because of danger like radiation or absence of civilization out there.

Some day in the future, traveling to Mars will be routine and people would barely think on those that made it possible.

How much people think about the incredible thing it is we could travel to the other side of the planet on a single day?
