Elon Musk's Starship rocket faces crucial 10th test flight following multiple previous failures as SpaceX works toward moon and Mars missions.

Flight 10's goals will be similar to those of Flight 9. SpaceX plans to bring Super Heavy down in the Gulf of Mexico about 6.5 minutes after launch and guide Ship to a controlled splashdown in the Indian Ocean, off the coast of Western Australia, about an hour after that.

The rocket was filled with millions of pounds of propellant and set to launch when SpaceX, around 8:00 p.m. ET, opted to call off the day's launch and turn the operation into a launch rehearsal, considering the weather forecast would remain unfavorable throughout the launch window.
