SpaceX has successfully completed a test fire of its Super Heavy rocket booster, powered by 31 Raptor engines capable of generating 16.5 million pounds of thrust. The booster is designed to carry payloads of up to 140,000 pounds to low Earth orbit and up to 37,000 pounds to Mars. The test fire marks a major milestone for SpaceX, and the booster's maiden flight is expected to take place as early as next month as part of the company's Starship spacecraft, which is designed to carry humans to the Moon and Mars.
