It is actually very common to use "Cloud Seeding
" to cause the clouds to start raining, after
which they will lighten up or disappear. Either way, the risk of rain is near-eliminated.
I believe it is the Russians who frequently use military planes equipped with the specific equipment to clear the skies for their national holiday.
The planes cause the clouds to rain down away from the destination, thus making sure that they don't reach the parade or test site.
If clouds posed such a large problem for NASA, I am sure they would find a way to cope with it - Without HAARP.
jameshawkings beat me to it.
