GUADALAJARA, Mexico – In order to make the figures work for Elon Musk’s plan to put settlers on Mars, SpaceX will have to build boosters and interplanetary spaceships for less than the price of a Boeing 777x jet, on a shorter time frame.

What’s more, Musk is aiming to ramp up to building 1,000 of those spaceships. That’s three times the number of 777x orders to date.

So what else is new?
