While the bat was battling the joker, the joker launched a missile and batman cap got caught on the top of the missile.
While being lunched in to space he disabled the blowup system, also while being launched into space batman or the joker did not know but nearby a young photo man took a picture and his name is Alejandro. So then he was lost in space, but luckily he was wearing his space suit under his costume and so he activated his suit and he was able to breath.
