i was in a bike shop yesterday (salvagetti's, downtown denver) and they had a surly moonlander with really fat tires.
got me to wondering.
could one ride a bike on the moon's surface?
i have no idea what the bright side temp is.
is space absolute zero? if so, would you have to have all lubed parts degreased to prevent the lubes from freezing and preventing riding?
what about the air in the tires? would you have to use solid tires?
i suppose the space suits' bulkiness would be an issue. put on huge pedals, snort! and you'd use up air faster.
imagine the cost to have nasa run one up there as part of a mission. probably a one way trip.
ok, do-able, but not practical.
any rocket scientists out there to offer comment? of all the sci-fi authors who wrote juvenile stories, clarke, heinlein, asimov, anderson i think the only times a bike was mentioned was when the kid rode it on earth. transport elsewhere was powered.
