Priroda was the last of the scheduled five Russian modules of the Mir space station complex and was launched from the Baykonur cosmodrome by a Proton-K rocket to dock after 3 days rather than the usual 9 days. The launch itself was 3 days earlier than the planned date in order to facilitate an American microbiology program.

Khrunichev State Research and Production Space Center is a Moscow-based producer of spacecraft and space-launch systems, including the Proton and Rokot rockets and is currently developing the Angara rocket family. The Proton launch vehicle launches from Baikonur and Rokot launches from Baikonur and Plesetsk. Angara will launch from Plesetsk and Vostochny.
