No, going to the moon and back was a week long, and going just TO Mars is 9 months long at the closest point.
Your looking at least at a 10x-20x increase in radiation dose over the mission which would be around 1Sv to 2Sv. That’s a very high lifetime dose in a short period of time.
Not to mention, there is still a scale of size, time and resource contraint. We can’t send humans to Mars with all the tools they don’t know they need yet, just like we can’t send the rovers with all the tools we can imagine.
For humans to benefit from rapid discovery on Mars, they’d need to be able to produce those tools, chemicals, power, etc.
It would take decades to set up anything useful for a longer term mission on Mars, and it again becomes a numbers game. The longer period of time you have to account for, the wider the room for error. I don’t know many people who would be comfortable traveling through space knowing that they may not see Earth again either.
