Did you consider the aerobraking part of arrival? That must be the limiting factor for a given size and weight.

I was, quite obviously, refering to the use of space. Very different between ISS and Starship. You chose to misunderstand.

Funny, how you build up unsuitable scenarios and unreasonable comparisons.

The ISS is full of science racks. What's left are mostly corridors for passing, tht take up a lot of space because of the size and shape of the modules.

Buildup of Starship is very different. Little space needs to be wasted like this.

Prepacked meals like on the ISS are very weight and volume consuming. Ingredients during transit to Mars will be taken out of large containers.

The Earth is flat, and everybody knows it. ;)

Yes it is. Not on early flights. 100 people to Mars, when there is an operational settlement, ready to house and feed them on arrival.

Engineers that have developed the ISRU tech, will IMO be part of the first crew.

Elon hinted, that he sees the biggest risk for the chopsticks and they have a spare ready.

True about the total number of launches. But Falcon has now far exceeded Soyuz on reliability.

That's one possible interpretation of the difference.

Another is that the anonym writer expresses the general feeling about it, while Kathy Lueders is managing expectations, the way Elon frequently does.

To know more, we need to go to Mars with crew.

They have it on Falcon boosters. Need to adjust the parameters. They needed some tries for Falcon. But they have it now.

I'm fairly certain spaceX plans on at least supporting a moon mission in the near future before Mars is on the table if memory serves me right?

SpaceX will sure love to provide transport to the Moon. It will pay.

They won't let themselves be distracted from Mars by this.

The substantial atmosphere and gravity is what makes mars a much harder problem. Mars and the moon will kill you just as quickly and in almost the same manner.

That's a myth spread by some people in NASA a few decades ago. In ancient times, when I was still young. Mars atmosphere makes everything easier. Landing takes substantially less delta-v than on the Moon.

Launch is harder due to higher gravity, but then is made easier due to ISRU enabled by the CO2 in the atmosphere. There is a huge amount of nitrogen too. Essential for breathable atmosphere.

The atmosphere protects from micrometeorites. It even reduces surface radiation, though not as much as the atmosphere of Earth does.

We have a vast store of data at NASA. From orbiters and from rovers on the ground.

the spaceship is ok,

That's very much contested. If it were true, the capsule would be back on the ground already.

They can't fly the 737 since titanium parts have turned out to be counterfeit titanium.

At least in this case the supplier raised the alarm. The components themselves may well be up to spec, only the source was not certified.

(aren't they detached after splashdown?)

I hope not. Floating discarded parachutes are not cool.
