folks being asked. I think it would be rates just after "Columbus
discovering America" in the US, but not that high elsewhere. The age of the
people polled would also matter....I think you would get a higher percentage
with that response at our age than among those <35.

But, this assumes a particular future. For example, in space exploration,
why this date instead of the date Sputnik was launched, or the day we first
soft landed a craft on the moon, or the first time we reached a planet?

will be true. If a significant part of humankind lives off planet, then
that might be true, but I'm guessing that living in habitats will not be an
attractive option compared to living in open spaces. If lift costs became
minimal, I could see space tourism....and I could definitely see all sorts
of automated equipment in space.
The first explorer to get somewhere does deserve some credit, but the
importance of first contact rests somewhat on what happens next. For
example, if it was discovered that the Vikings did reach North America, it
wouldn't make this anywhere as important as the start of the sea contact
between Europe and the Americas....because the latter had a tremendous
effect on our lives, and the former had minimal effect.
Nearly 40 years after the moon program, we have only marginal improvements
in lift costs, even though the government has invested billions in NASA
every year. Contrast this with the cost of computing power. I've
personally seen, since ~1984, a million fold drop in the cost of running
MCNP...a nuclear transport model.
The reason for this is clear to me....fundamental physics. This will need
to be chanced before it makes sense to send humans into orbit. In a sense,
the moon is somewhat like Everest....it's an achievement to get there, but
there is little practical to do once on gets there.
Indeed, I'd argue whether we have a moon base now will have very little to
do with how extensive our present man space program is. If we land humans
on Mars in 2015, 2025, 2050, or 2100, it will have minimal impact on how
extensive the utilization of space is in 2500. The reason I say this is
because the practicality of an extensive presence in space relies on new
technologies that are dependent on new sciences. There is no indication
that the development of the scientific knowledge needed to have a large
practical presence in the solar system is dependant on the nature and extent
of the manned space program in the first part of the 21st century. Thus,
the present manned space program finds a parallel in the Viking explorers of
the early 2nd millennium. Neither will have much of an impact on later
