What does the astronaut eat at the international space station? This has always been a topic of concern. Black caviar, crab sticks and other seafood products are the astronauts'home dishes, Russia's chief space nutritionist Dobrovliski said on the 25th. Dob Lo Wallis Ki said that catering for astronauts will also take into account their taste needs. "At present, we regularly deliver canned black caviar to the space station by cargo or manned spacecraft, as required by astronauts."

Besides black caviar, canned seafood is also a favorite food for astronauts. Dob Lo Wallis Ki said they would also send crab sticks, sturgeon canned food and seafood cooked by sea cucumbers and fish to the space station. These foods were tested before weightlessness.

Dobrowalski also said visitors will have the opportunity to taste the food of the astronauts at the upcoming 2013 Moscow International Air Show.
