These are scientists. Going on a semi-dangerous very serious scientific mission. And they're playing dress-up.
NASA just revealed the official poster for Expedition 45 and it is a Star Wars-themed masterpiece. These brave Jedi will be heading to the International Space Station beginning this September.
Entitled "International Space Station Expedition XLV: The Science Continues," the poster features the station's first year-long mission crew Scott Kelly and Mikhail Kornienko (right, bottom and middle), together with NASA astronaut Kjell Lindgren (left, bottom), Russian cosmonauts Sergei Volkov and Oleg Kononenko (right, top and left, top) and Kimiya Yui with the Japan Aerospace Exploration Agency.
