Thanks to the efforts of European Space Agency astronaut Samantha Cristoforetti, you can share the dizzying experience of floating through the International Space Station's many modules.
For the benefit of those of us stuck on Earth, Cristoforetti photographed the ISS interior in all of its glory, which you can now experience in this epic virtual tour of the entire ISS.
Cristoforetti holds the record for spending the longest consecutive amount of time of any woman in space, a lengthy 199 days and 16 hours. She returned to Earth last June.
In the tour, you can see places like the dining area, water dispenser, crew quarters, and airlock.
The photos below show off some of the many rooms of the ISS you can see in the tour:

Right now, there are six astronauts aboard the ISS as part of Expedition 44, including NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko.
Kelly and Kornienko are participating in the ISS's One Year Mission to study the effects of life in space on the human body. Scott Kelly's identical twin, former astronaut Mark Kelly, will be monitored on Earth during the same period as part of NASA's Twins Study.
The Expedition 44 crew has also been investigating crop growth in space and observing "potentially threatening" microbes.
