There ought not to be something in the whole universe
that a man can't poke his nose in to.
That's the way we're built
and I assume there's a good reason for it.
-Robert A. Heinlein
Much of the technology necessary to get to Mars has already been invented, and is already either in use or is being tested. "Technology" is a very wide definition of all the stuff we’ll need, so I’ve broken it in to several sections.
We may not need to use all this stuff, but it’s good to know it’s out there in case we do.
This lists the designs and stuff we’re currently planning to use in different stages of the mission. I suggest you read them in order. This is pretty much an overview of the mission.
