There are far to many problems to be overcome to send humans on extended missions. The main problem is cosmic radiation, not to mention length of mission, micrometeorites, weight concerns (supplies) and such.
The robotics of today and even the foreseeable future will never compare to human exploration. But I belive that robots are the way to go.
Mankind may set foot on Mars, and that is a huculean feat to say the least. But no way can humans do much more than that for at least 50 years. Robots not only can, but ARE doing these types of things far more cheaply, and with less risk.
I think you are wrong we will overcome dangers in less than 50 years.. I think we will be on Mars in the 2020’s..
There are too many problems with extended manned missions to justify any human travel beyond Earth’s orbit. Due to its lack of atmosphere, Mars will never be inhabitable. So what would be the point of going there to plant a flag and pick up some rocks? And distance, radiation, space debris, etc. dictate that we will never go past the asteroid belt.
Hmmmmmmm? Didn’t they say that about Olde Columbus, and Orville and Wilbur among others! Another few months and you will have thousands volunteering to go anywhere in this Universe where Zero Hussein Isn’t:-)
