The profitability of trips to Mars.

The first years on Mars will be difficult, there will be deficiencies of all kinds, the difference in gravity will cause problems, the closed environments will cause syndromes of all kinds, claustrophobia, health problems, etc., where will the resources come from to pay for those trips and everything else? , because bringing machinery, equipment or anything from the earth will be worth more than its weight in gold.

They would have to discover a diamond mine at ground level, without having to drill, or platinum or I don't know and even so, I doubt that it would be profitable to be able to build a city, a colony on Mars, that part is what I see as completely impossible, which of sending a StarShip and trying to land an empty StarShip on Mars without humans inside is the part that I see as most possible, perhaps not within two years, but perhaps within four.

Keep in mind that SpaceX is currently doing well due to the business involved in the creation of the Starlink satellite constellation and the services for transporting cargo and astronauts to space, whether satellites commissioned by private companies, space agencies or materials and astronauts that They have to go to the international space station, but on Mars there is nothing with which they can do business to make the construction of a city profitable.

It would be more profitable to create a city in the Australian desert or in Greenland or on some island in the Canadian Arctic or in the Algerian desert, but if Elon Musk wants to melt his fortune in a ghost city on Mars that would be his problem, now that whoever goes , I know it's going to be very difficult, I don't know what you think about this point.

On the moon, space mining activity would be profitable to supply these space factories, but on Mars, you could have space factories around Mars, but imagine all the distance and fuel expense to bring all the materials to Earth that you need. This is where the market would be, I don't see it for this century, perhaps in the more distant future yes, but not for this century.

In addition, there is another important issue, the StarShip can really land on Mars or the moon, right now the real commitment of SpaceX, what it has to do because it has a contract is to build a lunar lander with a variant of the StarShip, it would be The StarShip HLS would be for the Artemis missions led by NASA, NASA has a contract with SpaceX and the one above would be the designed ship or the ship that they have presented, but I highly doubt that this design is true.

That ship cannot land either on the moon or on Mars, because to begin with, there is no landing platform on the moon and nowhere outside the earth. On the moon, one leg can be perched on sand, another on a rock and another on inclined terrain, the center of gravity of the StarShip in this image is very high and the gravity on the moon complicates things a lot, it would be very easy for this ship to collapse as the cases of the Peregrin ship or Probe have shown, for example. of the United States and the Japanese SLIM ship of the Jaxa agency that have been left lying down.
