The Vostok rocket (Russian Восток, translated as "East") was a derivative of the Soviet R-7 ICBM designed for the human spaceflight programme but later used for other satellite launches.
The major versions of the rocket were:
- 8K72 - used to launch the prototype Vostok spacecraft
- 8K72K - a refined version of the above. This was the version actually used for human spaceflight
- 8A92 - used for launching Zenit spy satellites throughout the 1960s
- 8A92M - modified version for launching Meteor weather satellites into high orbits.
