SpaceX’s next generation vehicle—BFR—will be the most powerful rocket in history, capable of carrying humans to the Moon, Mars, and beyond.

This evening, SpaceX CEO Elon Musk gave an update on the design of SpaceX’s future massive rocket, the Big Falcon Rocket (BFR), during an event announcing the first passenger who will fly on the vehicle.

The rocket’s capability has changed. Musk claims that once the rocket is complete, it will be able to take up to 100 tons of payload all the way to Mars. That’s if the rocket gets refueled in orbit by some kind of tanker spacecraft. He also showed off a simulation of how the vehicle will land on the surface of Mars. “I can’t wait,” Musk said at the even. “I’m super fired up about this. This is amazing.”

The BFR is instrumental to SpaceX’s plans of sending humans to the Moon and Mars. In its final form, it will be a gigantic rocket, reaching a height of nearly 348 feet. That’s about the size of a 35-story building and roughly the same height as NASA’s Saturn V rocket that went to the Moon. It will also be powered by 31 main Raptor engines, a new SpaceX design that can provide a combined 5,400 tons of thrust.

Overall, the BFR is a combination of a giant rocket booster and a massive cargo spaceship, called the Big Falcon Spaceship (BFS), which can hold up to 100 passengers comfortably. Both pieces are meant to do powered landings, meaning they use their engines to lower down the surface of Earth — or other worlds. It’s akin to how SpaceX lands its Falcon 9 rockets right now.
