we have the technology to send someone to mars. but we have 3 huge, I mean HUGE, problems to overcome.
1) Cost. no money no trip
2) radiation. most people do not realize how much radiation there is in space. The people making the trip on the fastest route possible will have to endure 3 years one way in high radiation. (most of this is in cosmic rays) and no making the ship with 3 foot thick lead walls won't help. by the time they get there they would have already received a lethal dose of radiation. also 3 years in space makes you very very weak and osteoporosis will have long set in and you would be strong enough to lift your own body weight.
3) how are you gonna get them off the mars planet to return home? there is no martian cape Canaveral.

The United States has already landed unmaned exploration vehicles on Mars, but since there's only 3 years left in this decade I don't think there would be enough time to get a maned exploration on Mars.

Personally, I see no point in sending a man there. Nor a woman. We already know that the environment on the Moon and on Mars is hostile to humans. That the trip would be seriously dangerous. And that manned missions are much more expensive and complicated than unmanned ones.
Right now, there is no science out there that cannot be better carried out by a robot.
Until we actually have the technology to live on Mars, there's no point in sending a person there. Sending one just there to find out if is possible is rather stupid.

Almost certainly not. The US is however planning to send someone to mars in the 2020s or 2030s. The orion project is preparing to send people back to the moon by aruond 2020 as a beginning for a mars mission. Technically we already have the necessary tecchnology to send people to mars. Its the cost that's holding us back.

As the economies of countries fail, less money will be available for non-essential space ventures. Also, the more we discover about Mars, the less need to endanger humans by going there. I don't think we will be there even by 2020, and hope the think tanks of the world come to that realization.

Not even close.
We have to rebuild our long lost technical capacity and drive first.
Our present management systems place extreme burdens on such explorations beyond the straight forward tasks to just get there.
Our entrepreneurial spirit has been squelched. The value of manned Martian missions is dubious versus the potential economic and ecological boon from mining and refining the vast deposits of Helium-3 on the Moon.

All of the national space programs are rocketry based 'bigger is better' efforts. If anyone reaches Mars before 2020 it will be by application of radical technology and radical thinking. That is far more likely to come from private mavericks.

no, if by "this decade" you mean before 2010. Someone could've gone there by 2020 though

No way. Its tough enough getting back to the Moon.
