The main tech that the launch will put to the test, however, is the Black Brant sounding rocket itself -- mainly its motor in a two-stage configuration. In addition, the launch will test a new way to fabricate payload, as well as three new carbon nanotube composite materials.

According to the agency:

These technologies will bring significant value to a wide range of aerospace and defense products --including launch vehicles, spacecraft, aircraft and marine vehicles -- from the estimated 40-60 percent mass savings, increased technical performance and reduced maintenance over traditional materials.

The encircled parts in the map above show areas where the launch and the vapor clouds will be visible, but if you live elsewhere, you can watch the live coverage on UStream. Note that if the weather isn't ideal for a rocket launch tomorrow, NASA will postpone it (in fact, the original date was October 6th), as it has a launch window of October 6th to 12.
