Elon Musk's goals for the BFR system are clear, he wants nothing short of making humanity a multiplanet species; with a moon base, a manned mission to Mars in 2024, and rocket-trips around Earth too.
The Mars Scientific City aims to be a fully functioning simulation of what it will be like on an actual Mars base. Scientists can spend a year there completely isolated from the outside world.
Elon Musk has posted a simulation video of the planned Interplanetary Transport System ahead of his main speech which he will be giving at the 68th International Astronautical Congress in Australia.
Musk outlines his Interplanetary Transport System which he says will be refueled in space, carry over 100 people, be the biggest rocket in history, and will be "great fun" to travel in.
