missions on the International Space Station (ISS)．ISS crewmembers

usually live in space for at least a quarter of a year.They work five

collection of family photos，messages，videos and reading material for

the astronauts to look at when they will be floating 370 kilometers above

the Earth.During their mission，the crew also receives care packages with CDs, books，magazines，photos and letters.And as from early 2010，the
