SpaceX tried to fly its big rocket, Starship. But it had problems. A door did not open all the way. So, it could not let out the fake satellites. The rocket started to spin and fell into the ocean. It broke into many pieces. Elon Musk, the boss, said they learned a lot. He wants to try again fast. They used an old part of the rocket, but it also broke in the water. They wanted to test a heat shield, but they could not. NASA needs Starship to go to the moon. So, these tests are very important.
