is a skill pretty much taken for granted now, but it wasn't
. Accurate maps were once prized state secrets, laborious efforts that cost a fortune and took years (or even decades) to complete.
How things have changed. (Yours now, $110
) It took almost 500 years to map North America, but it's only taken one tenth of that to map just everything else. In the last 50 years, we've been able to create acurate atlases of two planets
and one moon
(with a second
in the works). Actually, we've done a lot more than that
. We're actually running out of things to map.
