Full Scale Test Launch

May 9, 2019

Polaris was first launched in early May 2019, to an altitude of 11,254 ft.

SA Cup Competition Launch

June 20, 2019

Polaris was subsequently lost in a motor catastrophe at take-off during its competition launch. Thermal expansion sustained from higher-than-expected on pad temperatures and longer on-pad wait times resulted in an over-constrained mount, leading to over pressurization and subsequent disaster.
