Abstract : The Hydra-Iris is a two-stage system, employing a cluster of three Mk 6 Mod 0 Sparrow motors as a booster and an Iris sustainer that is capable of being launched from any spot on the ocean's surface. Two Hydra-Iris vehicles with payloads were designed to telemeter performance functions, to provide an insight into the feasibility of placing scientific payloads in a water-launched vehicle, and to supply telemetry data relating to the in-flight operation and reliability of two infrared radiometers and one ultraviolet radiometer that are so calibrated as to display a gradient or profile of the earth's terrestrial horizon. Two such vehicles were launched from approximately 500 miles at sea, and the 121-pound payloads were placed 182 statute miles above the earth's surface. Telemetry was received on the entire first flight. No trajectory was available, and only partial radar tracking was received on the second flight. The data is being analyzed and will be reported separately.
