Thursday, SpaceX got its huge Starship rocket off the ground, but just minutes into its test flight, it exploded.
The company, which is run by billionaire Elon Musk, called the blast a "rapid unscheduled disassembly before stage separation."
Thursday, there was a short delay in the launch, which took place on the Gulf Coast of Texas.
It's not clear if the rocket blew up because of the technology problems that caused the delay.
Starship is described as a "transportation system that can be used over and over again."
This was the second time SpaceX tried to launch the rocket. This week, technology problems stopped a launch that was supposed to happen.
