Some speculation about the MCT

Elon Musk of SpaceX has big plans for going to Mars, and they involve a very big rocket, the Mars Colonial Transporter. No official details have been released, but as this article shows, it’s possible to put together a pretty detailed picture of what the MCT might look like given what’s already known about what SpaceX is working on. And it’s big.

The single-core booster will launch and land in a similar fashion to the first stage of the SpaceX Falcon 9. However, it may require as many as 30 sea-level Raptor engines in order to generate sufficient thrust. Consequently, it could be enormous: 49 feet( 15 meters) in diameter and 394 feet (120 meters) tall—taller than the Apollo Saturn V rocket, and some 50 percent wider than the launch vehicle that sent men to the Moon.
