The largest, most powerful rocket ever built is about to launch on its sixth test flight. SpaceX's Starship upper stage and Super Heavy booster are stacked next to the launch tower at the company's Starbase launch and test facility in southern Texas ahead of the vehicle's next mission, which is scheduled for tomorrow evening (Nov. 19).

The latest flight test comes roughly a month after the Super Heavy booster was successfully caught by two robotic arms and returned to the launch site during the Starship's fifth flight test. The sixth flight test hopes to build on that momentum with upgrades made to both hardware and software controls.

SpaceX’s Starship rocket will be launched for a sixth test flight next week, the latest experiment by the Elon Musk-owned aerospace firm to create reusable spacecraft after a previous test resulted in a “seminal moment” for the company.
