At this morning’s International Astronautical Congress in Adelaide, Australia, SpaceX founder and Lead Designer Elon Musk announced the most ambitious plans yet for the colonization of planets and satellites beyond Earth, including the establishment of a lunar base and a permanent Mars colony by 2022.

“The future is vastly more exciting and interesting if we’re a space-faring species than if we’re not,” said Musk during his keynote. “It’s about believing in the future and thinking the future will be better than the past.”

ON-ORBIT REFILLING

Starship leverages tanker vehicles (essentially the Starship spacecraft minus the windows) to refill the Starship spacecraft in low-Earth orbit prior to departing for Mars. Refilling on-orbit enables the transport of up to 100 tons all the way to Mars. And if the tanker ship has high reuse capability, the primary cost is just that of the oxygen and methane, which is extremely low.

I'M A TITLE

The timetable for implementation of the Mars colony is shockingly imminent: by 2022, a minimum of two cargo ships will land on the red planet, using robotics to begin setting up power, mining and life support infrastructure while confirming water resources and potential hazards. Just two years later in 2024, two ships will carry humans to the surface for the first time, who will build a propellant production plant and begin preparing the base for expansion.

The plan involves focuses the company’s energy entirely on one rocket, the SpaceX BFR, which will power the existing Falcon 9, Falcon Heavy and Dragon models to allow for the service of both the International Space Station and interplanetary missions.

LANDING ON MARS

<<<<<<>>>>> 

Starship will enter Mars’ atmosphere at 7.5 kilometers per second and decelerate aerodynamically. The vehicle’s heat shield is designed to withstand multiple entries, but given that the vehicle is coming into Mars’ atmosphere so hot, we still expect to see some ablation of the heat shield (similar to wear and tear on a brake pad). The engineering video below simulates the physics of Mars entry for Starship.
