18. Possibly, however...

One thing is for sure. Hibernation is not likely going to be used on a Mars mission considering that they would likely not be doing a mere boots on the ground mission after months in transit each way. They will likely be staying there a while.

I guess one could argue that consumables would be a huge issue on a Mars mission. Months in transit; possibly months on the planet. If we don't want to embrace cannibal astronauts they are going to have to take along a helluva lot of food and water.

This brings up a topic that the Orion capsule is in no way Mars mission capable. It just isn't big enough, let alone able to land on Mars. A docked Mars lander would have to be significantly larger than the Orion itself. Maybe they could send a landing craft ahead of time.

Plus, how does one shield the Orion astronauts from a probable CME? If the Sun belches one of those, those guys would be toast, maybe literally.

It is a very tough mission no matter how one looks at it.

And no, we are not even close to having hibernation technology.
