was launched from Woomera, propelled by a Raven VI and Goldfinch boost,
the payload head comprised a prototype star-pointing ACU with a University
of Leicester stellar X-ray astronomy experiment.
Preparation: SL812 had been the subject of much pre-flight
technical discussion on its aerodynamic stability, but the actual flight
showed no signs of flutter.
Flight: The vehicle
successfully propelled its heavy star-pointing ACU to 219 km (136 miles)
with no sign of flight instability. Unfortunately this Phase 1 version of the Stage 5 ACU then failed to lock, see below.
parachute recovery system did not work.
noted above, the prototype star-seeking payload ACU (Attitude Control
Unit) failed, as it did not acquire the correct target stars because of
faults in the magnetometer & Moon sensor areas. Hence the University of
Leicester astronomy experiment was unsuccessful.
