Astronauts perform a scientifically planned exercise program, largely to counter the atrophy some muscles experience in a weightless environment. Cards and other games, books and taped music can be taken onboard.
Tape recorders are available.
Sleeping accommodations aboard the Shuttle vary, depending on the requirements of the particular mission. On the first flight, astronauts Young and Crippen slept in the commander and pilot seats. They wanted to be instantly available if needed. Later crews slept in their seats, in sleeping bags, in bunks, or by simply tethering themselves to the orbiter walls. A bunkbed kit was made available by the time of the STS-9 mission.
