: At The International Astronautical Congress in Adelaide, Australia billionaire founder of SpaceX presented an updated plan for colonizing Mars.
Musk previously called it the Interplanetary Transport System, but this year he adopted a new name: the BFR, which is short for "Big F---ing Rocket.” SpaceX's goal is to make it cheaper to ride to Mars than to buy a house, with a cost at or below $100,000 per passenger. Making both the booster and spaceship fully reusable is key to vastly reducing the steep costs of launching people and cargo off of Earth. The company is already performing simulations of its Mars spaceship, including slowing down in the planet's atmosphere and sticking the landing. Musk offered one final vision during his presentation, saying this spaceship could provide 30-minute flights from almost any point on Earth to another, putting the Concorde jet to shame.
