A space processing applications rocket, SPAR V, was launched at 11am CDT September 11, from White Sands, N.M., the Marshall Star reported. The SPAR V science payload contained 4 experiments to be processed during about 4min of near-zero gravity achieved by the suborbital flight. The flight appeared, from limited data, to have gone extremely well, lasting about 15min and reaching a height of around 102.5 statute mi. The payload was recovered about 55 to 60mi down range in a low mountain area. The payload had no external damage and had been returned to the missile range.
Two of the experiments studied resolidification of molten materials in low gravity, from photographs made at 1-sec intervals during the process. Another experiment verified results of a SPAR II experiment during which an immiscible liquid processed in an electric furnace exhibited unexpected massive separation. The fourth experiment both melted and crystallized several samples of materials during the low-gravity processing period, while a camera recorded particle behavior.
