"And finally, there's the BFR: the ship Musk wants to use to colonize Mars.
On paper, SpaceX's Big Falcon Rocket looks like the megarocket to end all megarockets. It's a completely reusable launch system and features a massive spaceship on top of an equally massive booster powered by 31 SpaceX Raptor engines. (The Falcon Heavy uses 27 of the company's Merlin engines.) [The BFR: SpaceX's Mars-Colonization Architecture in Images]
The combined rocket and spaceship will stand 348 feet (106 meters) and will be able to launch 150 tons (136 metric tons) to low Earth orbit (LEO), making the BFR more powerful than NASA's Saturn V moon rocket, which could launch 135 tons (122 metric tons) to LEO. (The Falcon Heavy may be the most powerful rocket in operation today, but it would take more than one to match the Saturn V, Musk said.)" Space.com
I hope to see the BFR fly. pl
