Design
The Zarya spacecraft would have differed from all previous spacecraft by having an array of a dozen rocket engines for making a soft landing upon return to Earth, without using a parachute.[

Mission
Zarya spacecraft would have brought crew and supplies to ''Mir
''Mir'' (russian: Мир, ; ) was a space station that operated in low Earth orbit from 1986 to 2001, operated by the Soviet Union and later by Russia. ''Mir'' was the first modular space station and was assembled in orbit from 1986 to&n ...

It would have had a normal crew of one or two and offered the possibility of carrying a maximum of eight to twelve if used as a ''Mir'' lifeboat.
