He might care because he wants to go to Mars and so presumably it's totally reasonable to assume he might have the opportunity to go to space more than once. He might want to do a 3 day tour of the Earth as the beginning of that. He might just because he's the kind of guy who pretty much makes loads of his decision 'because he can'. Plaid? Model's S 3 X Y (sexy)? acceleration speeds that are almost unsafe for normal drivers to be handling? A lot of his decisions are outside the norm, which is why (some of us) love him.
