Hyflex

 1996-S07


The HYFLEX lifting body was launched on the first test flight of the J-1 rocket. The J-1 performed perfectly and Hyflex reentered the atmosphere, proving performance of the heat shield tiles and control systems. However, the vehicle's flotation device separated after splashdown and Hyflex sank before it could be recovered. 12 of the 14 experiments returned their data via telemetry successfully, but the post-flight condition of the thermal protection system could not be inspected.

Splashdown was at 143.5E 28.5N.

Mass was 1054 kg, size was 4.4 l 1.4m dia.
