Sparta used surplus American Redstone rockets as its first stage, a Thiokol Antares-2 as a second stage, and a WRE BE-3 Alcyone solid-propellant engine as a third stage.[2][3]

A first stage was recovered from the Simpson Desert in 1990 after being found in searches by explorer Dick Smith the previous year.[4]:76–80

Launches

Several Spartas were launched between 1966 and 1967 from Woomera Test Range LA8 in Woomera, South Australia as part of a joint United StatesUnited KingdomAustralian research program aimed at understanding re-entry phenomena, and the US donated a spare for the scientific satellite launch into polar orbit.[5][2][3]

The first launch was a failure, while the rest were successful.[3]
