SpaceX looks ready to proceed to the next crucial phase of its Starship spacecraft development program: A 15km (50,000 feet) test flight.

This would far exceed the max height that any prior Starship prototype has achieved so far, since the current record-setting hop test maxed out at around 500 feet.

Elon Musk says that SpaceX will look to make its first high-altitude attempt sometime next week.
