Design
Hopi-Dart was a two-stage vehicle, combining a solid-fuelled Hopi III first stage with an unpowered "dart" second stage.[1] It was originally capable of carrying a payload of 4.5 kilograms (10 lb) to an apogee of 64 kilometres (40 mi); an upgrade, sometimes known as "Hopi Plus", increased the apogee to 97 km (60 mi).[2]
Operational history
Eleven test and eleven operational aeronomy missions were flown, with Wallops Island, the Tonopah Test Range, and the Cape Canaveral Air Force Station Launch Complex 43 being used as launch sites. Four of the test launches were failures.[1]
