Nasa is going to populate Mars, so in us all tax money goes in to the space

everybody is going to populate mars eventually, so this means nothing. nasa's budget is less than half percent of total us budget, you could check it on special wiki page https://en.wikipedia.org/wiki/Budget_of_NASA if you weren't so stupid

Nasa is going to populate Mars, so in us all tax money goes in to the space and to army and army actions.

You need to look at the budget, you silly.

The only one that has some kind of chance to get at Mars is Musk, the guy behind Paypal, SpaceX and Tesla Motors, as he is stockpiling money and technology to get there and is very motivated.

NASA is running on a shoestring budget since the end of Apollo.

Any trip to mars with current space propulsion technology is basically gonna be a one way trip. Sure we might be able to get a handful of people there, but it would be so cost prohibitive to get them back home that it just won't happen. We need a new form of space propulsion that can exert something like 1 kilonewton for extended time frames. There is nothing that exists like that.

Yes, with the turd "let's do a US coast-to-coast carrying ALL our own fuel" approach of Apollo and earlier missions (also Shuttles weren't terribly smart either, with their "let's make a vehicle that can lift more or less the same payload of a Saturn V, but let's waste it in carrying up and down a huge, heavy and mostly pointless vehicle instead of keeping the capsules+ space stations approach").

If you use the more sane "why not refuel along the way" approach, costs go down and it looks less stupid.

It's going to be relatively cheap (compared to the average war), if the general plan is to send tanks of propellant there in mars orbit, then when they are there and safe you can send the manned vehicle.

If they place fuel manufacturing on the moon (nothing terribly complex, it's just take water and hydrolize it to make fuel, using the plentyful solar power that in the inner system pwns even nuclear power.

EDIT: Googling on the matter I found this highly interesting link.

US-based equivalent are NERVA engines (as noted there), which existend and were tested in real life, they weren't just paper engines. There were also (on paper) the more advanced LANTR (they add oxygen after the nuclear reactor to get an afterburner-like effect).
Point is, neither is worth the annoyance. They are just a bit better than plain chemical engines, but are ludicrously more dangerous and expensive.

If you want 1 kilonewton for long times, the only thing that can deliver is the good ol Orion Drive. Aka nuclear pulse propulsion.

In reality you don't need so high accelerations, you can get anywhere with a constant 3-or-so milligee acceleration. But that can be done only by very very OP fusion engines or exotic external-powered systems like kinetic impactor propulsion (the more powerful cousin of lasers shining on solar sails).
