Bientôt une taxe d'eau sur Mars
It's amazing that we haven't been to Mars yet. WTF happened to NASA, What happened to Humanity dreaming?
There is no competition to the Usa. When you have no competition you start behaving like a monopoly and that's exactly what the Usa are doing. Start a second cold war, have another country competing for space superiority and we'll put human on mars soon enough.
I'm not saying that The cold war was good, nor am I wishing for a second one, but it clearly made it happen for the moon IMO.
what are you talking about lol? What monopoly? NASA is not Hydro Quebec. It doesn't generate revenue and the government spends billions on it every year for research. Its not a question of competition lol

Wether it's public funding or private money, with no competition you get complacent and stop pushing yourself.
SpaceX will change things though.. They already have a better track record than NASA or any space program, and are able to ship satellites to spaces for a fraction of the price.

Placing cargo in space is something any company with a decent aerospace department should be able to do.
Placing said cargo in orbit is slightly different and also a bit more crafty but not too difficult, the arithmetic is known and not even that hard as the gravitational theory is regularly mastered (albeit usually in 2D rather than real life 3D) by high-school students.
Sending cargo to the moon wouldn't be that hard after placing it in earth orbit but sending it to Mars? That's a whole different game.
The moon is around 385.000km from Earth, it varies but from memory it's largely the accepted average distance.
Mars distance from Earth varies of course, but by a much wider margin than the moon. It can be as far as 400 MILLION kms (but for practical reasons it would make sense to send people there when it's closer to the Earth) and can be as close as around 45 million kms. Keep in mind both planets revolve in the same direction around the sun so when they're far apart, they're far apart for a rather long time as Mars rotates around the sun almost twice as slowly as the Earth.
From memory it takes close to 2 years on Earth for Mars to go around the sun once which means we pass by the "closer" flyby only about every other year so missing the "window" on the way there would not be too bad as you would be able to survive two extra years on Earth with relative ease compared to on the way back, as being stranded on Mars an extra 2 years would likely kill you.
We will not see people on Mars during our lifetime. To be honest I don't even think we'll witness an ATTEMPT to place humans on Mars. There are far better (and more lucrative) ways to spend money on space exploration than going to Mars.
