Life aboard the ISS (pictures)

Astronaut Scott Kelly and cosmonaut Mikhail Kornienko are preparing to spend an entire year aboard the International Space Station, hoping to give NASA more insight into the effects on humans of long-term exposure to space, and paving the way for expeditions to Mars in the coming decades.

The yearlong ISS mission will begin in 2015 and for Kelly and Kornienko will present the challenge of living in a confined space -- eating, sleeping, exercising, and relaxing in a highly technical, cramped environment.

What will that life be like? In this gallery we'll get an idea, by taking a look back at previous scenes of life among the stars.

Above, we see cosmonaut Yury Usachev sorting food in the kitchenlike corner of the Zvezda service module aboard the International Space Station on July 16, 2001.
