I doubt that's the case. Suits will be tough, and undoubtedly come with patch kits, and folks will use the buddy system.

A penny-sized hole would give time to patch, and suits would likely be designed to compartmentalize in a leak. In a true worst-case scenario, chimp studies in the 1970s showed they could survive several minutes of total vacuum.

How long a human would survive is one thing. How much medical care they'd need is another. They'd be on Mars, not Earth, and I imagine being a quadruple amputee on Mars would effectively be a death sentence.

Musk's plan is to have ships going back and forth every launch window. I'd expect anyone disabled like that to be offered a trip home.

I'll believe that when I see it.
