"There is such a tradition in NASA - after the whole cycle of training, before the crew goes on a flight, the so-called "cake ceremony" is appointed," she told RIA Novosti.

According to Kikina, on this day a huge cake with the emblem of the crew is being prepared and specialists are invited to ensure the operation of the simulators and all the training of the crew.

"Astronauts and cosmonauts say words of gratitude to employees, everyone who provided them with training, and all together eat a piece of cake, communicating in a pleasant environment," she explained.

Earlier, cosmonaut Anna Kikina said that the flight on the Crew Dragon was wonderful.

Roscosmos clarified that Kikina will continue rehabilitation in Star City for several weeks.

On March 12, SpaceX's Crew Dragon manned spacecraft with the crew of the Crew-5 mission and Russian Anna Kikina splashed down in the Gulf of Mexico off the coast of the US state of Florida after a mission to the ISS.
