When do you think the mankind will finally land on Mars?

Not before the 2030's. The problem is not just the rocket to get there, it's also due to the astronauts themselves. The rocket will be done in a couple years, but not their crews.

Astronauts will need very specific training for Mars which will be much more extensive than for the Moon because it takes much longer to go there and you have to stay there for much longer before you can actually go back to earth (260 days to stay on the planet on most trajectories before you can go back home to earth). In other words, they need training to be able to live in such a hostile environment for 2 years straight, travel time included.

They will probably also need a constant stream of supplies from earth just to be able to live there, like food, water and oxygen. Starship can transport a lot, but I doubt it can hold enough supplies for an entire crew for such a long time. Which is especially true if they are supposed to build stuff there, something they will have to do or need to be done by robots beforehand to avoid radiation since Mars doesn't have a magnetosphere anymore.

I think a lot of people like you still think of 2030 like way into the future, people keep forgetting 2030 is in less than 8 years time. Nothing will change in 8 years, they can go to mars and come back, maybe, but not land, no way it could be done before 2040. And even if they start planning the mission today, it would take minimum 10 years to put the mission into action.

also replying to @drkohler here.

With 2030's I meant the suicide mission I posted above, meaning a one-way mission with no plans of any return trip. Since these astronauts would know they're doomed from the start, space radiation would thus be considered not something they'd need so much shielding for - they would die from radiation (or anorexia or simply lack of supplies) on the planet some time after landing anyway.

That is of course only if someone would be stupid enough to go and approuve such a ludicrous plan. Otherwise yes, 2030 won't nearly cut it, not even sure if it could happen in our lifetimes without such a mission.
