This is a good math opportunity for any humans, unschoolers or not.
If it takes a magnification of 75 for Mars to look as big as the moon,
that's not nearly as big as the moon.
Opportunities that are once-in-a-lifetime (and I think it's cool; not saying
it's not) aren't unschooling opportunities. They're once-in-a-lifetime
opportunities and those who are interested will be interested regardless of their
school status.

Unfortunately, the original message is simply in error. This *October*,
Mars will reach opposition with the Earth, and while it's a good apparition,
August 2003 was quite a bit closer.
And, to give you an idea of what all of this means in terms of observing
Mars, I pushed my telescope with a 16" (40 cm) wide mirror to several
hundred power (I don't have my logs in front of me, so I'm not sure what the
exact power was), under PERFECT conditions, and I was able to discern a few
of the most prominent of Mars' features.
Bear in mind, too, that observational astronomy is very much a learned skill
-- so where I could pick out features on Mars, a novice stepping to the
eyepiece for the first time might have seen little more than a smeary orange
disk.
I don't say this to discourage folks from observing Mars this fall -- but I
always hate to see people terribly disappointed when they are pumped up by
claims such as these, only to learn that, as is so often the case, there's
no easy shortcut to the most rewarding of experiences.
The availability of Hubble and other very high-quality images of a wide
variety of astronomical objects has made it all too common for a first-time
observer to expect to see what they've found in books and magazines. You'll
see many beautiful things through a telescope, and many will become only
more beautiful as your skills improve, but you'll rarely get views that
compare to the photographs.
Hope this helps -- and please feel free to ask me any questions that may
come up about astronomical matters; I relish the experience of seeing people
come to understand just how incredibly grand our universe is, and how much
they can learn about it with their own eyes.

Unfortunately, this happened in 2003, and will not happen this year.
See http://www.snopes.com/science/mars.asp
Fortunately, it happens every 15-17 years, so will happen again in our
lifetimes, so if you missed it then, you can catch the re-runs in 2018 :-)

Thanks for the extra insight! We're pretty lucky to
have a university observatory nearby and they love to
have people come out and peek and learn. We'll take
advantage and pick their brains when October rolls
around!
