Are Dippin' Dots like the ice cream that astronauts eat? You know, astronaut ice cream?

“While Dippin' Dots ARE out of this world...no, they aren't astronaut ice cream. Dippin' Dots ice cream is flash frozen and can still melt if not stored at the appropriate temperature. The foods that the astronauts eat during their space missions are freeze-dried and in the case of ice cream, do not melt.”
