This is What Elon's Musk's Promise to Make Happen Next Year

This is What Elon's Musk's Promise to Make Happen Next Year.
But how realistic is it??

So here we have the mating of 2 Starships in Space. One impregnates the other with its fluids, or fuel. Enabling one Starship to travel to Mars, while the other returns safely to Earth.

But the Maths seems to not add up.

You see each Starship has 1200 tonnes of fuel capacity. But they are only able to bring 100 tonnes of payload into low Earth orbit. So to fully fuel a Starship in space, we would need to send 12 other Starships.
So why is SpaceX building this?

Well as some suspect, part of it is for the dream of space gas stations. But it's also because most rocket fuel is spent just leaving Earth's atmosphere. Once you are out, just a bit more fuel can cut a trip to Mars down from months, to weeks.
