There are no human habitable worlds. There are a few places in the
Solar System where we might find life, and those have active missions
or missions in the works. One of the most important questions we're
still working on is the formation of planetary systems. So a detailed
look at another gas giant makes very good sense.

Mars is a world that can be settled by people. Not that terraforming it would
be practical with foreseeable technology, but people can live in underground
habitats, with the surface not being so inhospitable that they can't go to the
surface to set up solar collection mirrors, to collect resources, and so on.

Of course, much the same could be said of the Moon, but Mars does have
more resources, and the gravity there is not quite as low, although it is
significantly lower than that of Earth, which is still a problem.

Mars is no more habitable than the bottom of the ocean. Less. At our
current level of technology, there is no hope of people living on it
without extreme dependence on the resources of Earth. That's not what
I would call "habitable".
