It’s gonna take you to Mars.
Last time the US Congress checked with NASA, the cost to send a five-person crew to Mars was $50 billion. $10 billion a person. Elon thinks that to make the blue circle sufficiently large, it needs to cost $500,000 a person. 1/20,000 of the current cost.
That’s like looking at the car industry and saying, “Right now a new Honda costs around $20,000. To make this a viable industry, we need to get the cost of a new car down to $1.”
