Can't walk, can't dance when landing back on Earth

This wouldn't make an heroic film scene, but it would be correct

Dr. Charles said he thought NASA could already send astronauts to Mars and bring them back alive. But given the huge expense of such a mission, he said it was crucial that the astronauts arrived productive and in great health. 

“My goal,” he said, “is to see a program that doesn’t deliver an astronaut limping to Mars.” 
The additional goal of everyone remaining mentally intact and still speaking to each other is likely an even bigger challenge than keeping body and soul together on the long ride to Mars.

Interesting that NASA has the fantasy that they will bring people back from Mars - that's at least five years, round trip, with not much of a stop over on Mars. 

Human bodies not made for space
