The Sparta (or Redstone Sparta) was a three-stage rocket that launched Australia's first Earth satellite,WRESAT,on 29 November 1967. [1] [2] [3]
Sparta used surplus American Redstone rockets as its first stage,a Thiokol Antares 2 from Scout rocket as a second stage,and a WRE BE-3 Alcyone solid-propellant engine as a third stage. [2] [3] [4]
A first stage was recovered from the Simpson Desert in 1990 after being found in searches by explorer Dick Smith the previous year. [5] : 76–80
Several Spartas were launched between 1966 and 1967 from Woomera Test Range LA8 in Woomera,South Australia as part of a joint United States–United Kingdom–Australian research program aimed at understanding re-entry phenomena,and the US donated a spare for the scientific satellite launch into polar orbit. [6] [2] [3]
The first launch was a failure,while the rest were successful. [3]
