Get your wardrobe ready, Tuesday is Hawaiian Shirt Day, at least for those of you living on the International Space Station.
Officials at U.S. Mission Control in Houston will also be donning "aloha" shirts. It's all in honor of astronaut Edward Tsang Lu on his fortieth birthday.
Mr. Lu, who considers Honolulu his hometown, has an affection for Hawaiian shirts, and has been spotted wearing them since arriving on the Space Station in April for a six-month stay.
The commander of Mr. Lu's expedition, cosmonaut Yuri Malenchenko, has also become a fan of the colorful flowered shirts. Several new ones arrived at the space station a few weeks ago aboard a Russian resupply craft.
