What makes it difficult, however, is that you don’t seem to be much of a ‘people person.’
If you were more of a people person, we would have commissioned you aboard the Starship Enterprise. But since you don’t care much for the complications of dealing with your fellow man… we have another deep-space mission, more tailored for your tastes… a way for you to enjoy the benefits of high-tech civilization without having to put up with civilization itself. Let’s set you up to pursue the solo career of a deep space explorer. You can go ahead and hibernate through the boring parts of your mission, and not worry so much about being a few decades out of touch with your fellows by the time you get home. In fact, you pretty much don’t have to deal with people at all, but you can still enjoy a high-flying adventure of a life. Far, far away from the madding crowd, you get to play with your scientific instruments, serve your glorious civilization, and do interesting things with strange discoveries in exotic places.

The career might work out all right. Look what it did for Charlton Heston.
