The term 'HOME IN SPACE' can be solved by the three-letter word MIR. MIR was a Soviet/Russian space station that operated in low Earth orbit from 1986 to 2001. It was the first modular space station and was assembled in orbit from 1986 to 1996. The station served as an important research facility for the study of the effects of long-term spaceflight on the human body. It also served as a base for numerous international missions, including the first space tourist, Dennis Tito.
