Abstract:

Reentry weather measurements conducted under the Minuteman Natural Hazards Program are described. The missions described here are PVM-6 and PVM-7, which were postured to reenter through heavy weather. Documentation was accomplished primarily by instrumented C-130E and Cessna Citation aircraft, by high-power radar, and by satellite. The weather objective was met in a qualitative sense, in that the vehicles reentered through a thick cloud mass that was remarkably uniform horizontally in the reentry corridor. The weather Severity Indices WSI for the PVM-6 trajectories were 4.3, 5.9, and 3.6 for RVs 1, 2, and 3. The weather system was weakening by the time of the PVM-7 reentry, so that the WSI was 2.0 and 1.6 for RVs 1 and 2.
