Here is some more background on the specs of this mission in regards to weather and logistics:

The scenario for the test calls for a high-altitude balloon to carry the LDSD aloft from the U.S. Navy’s Pacific Missile Range Facility on the Hawaiian island of Kauai. The LDSD would be dropped from a height of 120,000 feet, and then fire its rocket engine to go even higher — 180,000 feet.

On the way up, the LDSD would hit a top speed of Mach 4, or four times the speed of sound. On the way down, the doughnut-shaped cushion — known as the Supersonic Inflatable Aerodynamic Decelerator, or SIAD — would be inflated to a diameter of 20 feet (6 meters).

Because so much depends on the drift of the high-altitude balloon before the launch, and the drift of the parachute after the launch, the winds have to be blowing in just the right direction for launch. If the winds aren’t right, the test won’t happen.

Well we hope that the conditions are proper soon as we’d like to see an actual flying saucer..wow.  More to come and updates as they get closer to launch!
