Serena Auñón-Chancellor, Alexander Gerst of the European Space Agency and Roscosmos cosmonaut Sergey Prokopyev docked with the ISS on Friday and came on board to join Expedition 56. The only thing missing were traditional flower leis.
The three crew members already on board, NASA's Drew Feustel and Ricky Arnold and Oleg Artemyev of Roscosmos, had a reason for wearing the bright blue shirts adorned with white flowers. The trio previously arrived at the ISS in March in a Soyuz spacecraft flying under the call sign "Hawaii."
The Hawaiian theme doesn't end there. The crew broke out guitars, drums and flutes for an impromptu jam session in April and named their group AstroHawaii.
There's no word on whether the space station is stocked with any Spam supplies.
