Resolves YES on any orbital rocket launch from a launch site located in an Australian state or territory, including external territories, before the end of 2024.
"Orbital rocket launch" means a launch intended to reach orbit, or nearly so, so as to demonstrate obital capabilities. Thus slightly suborbital trajectories will count, as long as the planned trajectory would be a convincing demonstration of orbital capabilities.
Only the planned trajectory matters - whether the launch sucessfully reaches the planned trajectory or not does not matter.
"Launch" means liftoff from the pad, however slight - the rocket can explode without clearing the pad and the market will still resolve YES, as long as the planned trajectory was orbital or near-orbital.
Only credible plans will count - this market will not resolve on someone launching a bottle rocket to an altitude of 100m and declaring that it was intended to go to orbit.
The relevant timezone for determining whether a launch is prior to the end of 2024 is the local time at the launch site.
