Hopi Dart

Launch vehicle · USA

Original archive entry. The text, images and links below are kept as they were written.

American sounding rocket, flown by NASA Huntsville on aeronomy missions 1963-1964. The Hopi-Dart vehicle consisted of a Hopi III booster as first stage, and an unpowered dart as second stage.

The second stage was an inert dart, 0.035 meters in diameter and 1.128 meters long that contained aluminized Mylar chaff and the payload ejection system. At first stage burnout (2.4 seconds), differential drag caused separation of the first stage from the dart. The dart then coasted to an apogee of 85 kilometers. The payload ejection from the dart was designed to occur at approximately T+ 135 seconds. The Hopi-Dart was launched from a rail attached to an I-Beam structure.

An FPS-16 radar skin tracked the Dart and then the chaff payload from apogee to an altitude of 70 km or loss of signal. Data were obtained by radar printout of time, elevation and azimuth angles, and slant range position, and also by reducing the radar plotting board which was a graphical location of the chaff by altitude, time, and position. Only three of this type system were fired at Cape Kennedy.

Payload: 4.99 kg (11.00 lb) to a 115.8 km altitude.
