SPACE CADETS / SPACE STATION GUIDED VIRTUAL TOUR.

Italian astronaut Samantha Cristoferreti demonstrates how hatches open and close between modules on the
International Space Station.  She is located in the "Columbus" module. See image below (upper
right hand corner).

NASA has posted a virtual tour video of the space station whereby astronaut Samantha Cristoforetti gives a tour of each major section of the International Space Station. 

The red circle shows
where you happen
to be on the tour of ISS

Everyone will come away with a different view of this video, but what fascinated me was how the astronauts move around the weightless orbit vehicle by using the railings.  If Samantha wants to stop and remain stationery she simply tucks her foot under a railing. 

This video has prompts that allow you to read details regarding the station.  Also, as you click through each space station module, the small image within an image shows you where you are in relation to the rest of the ISS.
