SpaceX would build a huge rocket: the BFR, or Big Falcon Rocket—or, more crudely among staff, the Big Fucking Rocket
The new rocket is still known as the BFR, a euphemism for 'Big (fill-in-the-blank) Rocket.' The reusable BFR will use 31 Raptor engines burning densified, or super-cooled, liquid methane and liquid oxygen to lift 150 tons, or 300,000 pounds, to low Earth orbit, roughly equivalent to NASA's Saturn 5 moon rocket.
