Given that Mark is about to be launched into space with only a strip of Hab canvas separating him from the lifeless void, we'd say he has good reason to be afraid. The bright side is that this will be the last time he has to do something like this—hopefully.

Mark must feel really weird to be leaving Mars. Although he hasn't had a great time during his stay, Mark has become used to his lifestyle there, no matter how bizarre it might be. That being said, we're still willing to bet he won't be back anytime soon.
