Over the course of the day, I will be popping in to retweet the best #ValentineFromSpace I can find. Bring on your cheesiest!Chris Hadfield

@Cmdr_Hadfield Betelgeuse is red. Rigel is blue. Neither of these stars shine as bright as you. #valentinefromspaceDale Foote

@Cmdr_Hadfield "My love for you burns brighter than a solid rocket booster, my Valentine." #ValentineFromSpaceMarjan

@Cmdr_Hadfield Love as a black hole : infinite attraction, so dangerous but absolute need to know what’s behind… #ValentineFromSpaceFlorence Porcel
