If you follow NASA HQ PHOTO or NASA Johnson then your feed has been full of photos documenting the preparations for the Expedition 47 manned mission to the International Space Station. Today is finally the day for launch, and within the hour a Soyuz rocket will launch from the Baikonur Cosmodrome in Kazakhstan carrying crew members Jeff Williams, Alexey Ovchinin and Oleg Skripochka on their way to the ISS.

While you wait for the launch, take a look at some of the photos from the last few weeks here on Flickr.
