Check Yes or No.
YES.
(Obviously, when you answer, you’re answering with respect to your own lifetime, not mine.) 
A year ago I’d have said, “Definitely”. Now I’m not so sure. I’ll give it a 95% chance. If we spiral into a Depression, there’ll be very much less of a chance of one; conversely if we discover life there, then we’ll almost certainly send an expedition.
50/50. I’m 24.
NO.
It could happen, but I expect that global warming is going to become an increasingly all-consuming issue over the next several decades, and there won’t be much enthusiasm or many resources available for the space program.

YES.
Recent findings give a pretty strong indication that there might be life there. Assuming we don’t fall into a global depression or war, I see no reason that we cannot accomplish this in the next 50-60 years.
YES.
It’s a question of drive more than anything else. I doubt that it will be a mission dominated by the USA, but I expect that it will launch in my lifetime, and probably even within my parents’ lifetime.
Of course, this question could include how much better our geriatric medicine is going to get. I’m sure that will improve as well.
NO
Or at least, I kinda hope not-- I think there are better ways to use limited resources.
No. Goddammit.
No. Far too costly for any one nation to bear, perhaps for the world as a whole to bear. Much better idea to send a robot, do experiments, and send samples back. No life support to transport, much less cost to liftoff, can have longer mission, no lives lost in case of failure. IF it ever happens, will not be until after 2050.
Possibly?
Not if the space agencies are smart. Why send men to do what robots can do better?
I wouldn’t think so.
- It’s too expensive
- It’s too dangerous
- The value of such a mission wouldn’t justify the investment
We’ve got to many ignored priorities here on earth to worry about joy riding into space.
Manned? No. Robotic sample retrieval, yes.
At least not based on currently available data.
Depending on what the samples returned reveal, that no can become an emphatic yes.
Yes.
By China.
It will be a stupid PR stunt, accomplishing nothing and costing a fortune.
Yes.
No. Ferchrissakes.
You and me both, kid. Before 9-11 and the economic meltdown and the Federal budget deficit reaching appallingly huge proportions, my answer would’ve been different.

No. The technological hurdles are too great, the cost is too high, the benefits are too small.
YES. And probably a private one, too.

Much as I would LIKE to see it, I don’t think the cost can be justified. We can learne everything about Mars from robotic probes. Pretty soon we will have a sample return mission, and that will answer most ofthe questions.
Still, if we could perfect a nuclear ramjet, there might be a chance.
