Will We Go To Mars?

I was wondering if humans could go to Mars?

Mars is like the moon, but here are the known obstacles:

Different orbit than the moon, making flights to mars about as rare as annually; the Moon goes around the Earth, Mars has it's own orbit.

How are we supposed to land there? There's half as much gravity (62%, to be precise) but, getting the ship on an angle to land without hurting the astronauts would be difficult.

And supposedly what would it be like on Mars?

This is just an Idea of what Mars would look like if we went there. From http://en.es-static.us/upl/2011/06/humans_on_mars.jpg

But obviously that won't be for a while. Because:

Where are we getting the ca$h from?

When is Earth going to line up with Mars?
