By the time astronaut Scott Kelly comes back down to Earth, he will have spent 342 consecutive days in space -- and one of those days is Halloween.
Even if he can't exactly go door to door to trick-or-treat, he's celebrating the spooky holiday all the way out on the International Space Station.

On Friday, Kelly tweeted a video of himself eerily floating around the International Space Station, wishing his followers a Happy/Creepy Halloween.
#HappyHalloween from @space_station! Have a great weekend, and be safe down there. #YearInSpacehttps://t.co/aRGMsRAF1D— Scott Kelly (@StationCDRKelly) October 30, 2015
Kelly, who is in space as part of a yearlong mission, embarked on his journey in March. On Oct. 16, Kelly became the record holder for the longest time spent in space by any NASA astronaut.
