In this sense, he stressed that “making life multiplanetary has a fundamental problem, which is the cost per ton for transfers to Mars“. He then explained: “Currently, It costs about $1 billion per ton of payload to the surface of Mars. That figure needs to be improved to $100,000 per tonne to build a self-sustaining city there, so the technology needs to be 10,000 times better. Extremely difficult, but not impossible“.

The start of travel on Tuesday, according to Elon Musk
Through their social networks, Elon Musk He stated that “the first Starships to Mars will be launched in 2 yearswhen the next Earth-Mars transfer window opens. These will not have a crew to test the reliability of an intact landing on Mars. If these landings go well, the first manned flights to Mars will take place in four years.”
He also noted that “the rate of flights will grow exponentially from there, with the goal of building a self-sustaining city in about 20 years. Being multiplanetary will greatly increase the probability of conscious life, as we will no longer have all of our eggs, literally and metabolically, on one planet.”
