Elon Musk has tested his enormous Starship rocket three times so far this year, and three times the rocket has gone pop. SpaceX, the company behind the venture, says every one of those spectacular failures is a valuable learning opportunity.

A major highlight is the testing of the booster's engine redundancy during its landing phase: one of the core engines will be intentionally disabled during descent, forcing a backup engine to take over.

Official SpaceX Starship ten launch coverage will start in about ten minues. Weather is indicating 55% chance of a launch.
