OS-1 Space Station

Russian manned space station. Study 1969. By 1969 the giant OS-1 space station had evolved to this configuration.

Although pursued at least to the mock-up stage, all plans for orbiting the OS-1 had to be constantly deferred until the N1 booster proved itself. The termination of the N1 launch vehicle program ended any possibility of launching the station.

By 1969 the OS-1 had evolved to this configuration, as described in the official RKK history. In 1991 engineers from Energia and other design bureaus taught a course on "Russian Manned Space" at MIT. Among them was Dr. Vladimir Karrask, the first chief designer for the UR-500 (Proton), who told of a shroud he designed for the N-1. The shroud was cylindrical - 6 m diameter x 30 m long - with a very "Proton-like" blunt conical top. He indicated that it had flown on the N-1. Another engineer, S. K. Shaevich, stated that flight hardware (including a backup) was ready for the N-1 flights. There were those who believe that the last two N-1 flights had the Karrask shroud, and possibly the OS-1 station, mounted on them. It was not known if any OS-1 stations actually reached any stage of completion. All plans for the OS-1 had to be constantly deferred until the N1 booster proved itself. This did not prevent the design team from undertaking an even more grandiose study - the MKBS - in which OS-1 derived modules would form mere subunits of a huge space complex. At any rate the termination of the N-1 launch vehicle program ended any possibility of launching the station - unless it was the same as the Mir 2 jumbo space station that was planned for launch by the Energia booster in the 1990's.

Associated Launch Vehicles
  • N1 1969 Russian heavy-lift orbital launch vehicle. The N1 launch vehicle, developed by Russia in the 1960's, was to be the Soviet Union's counterpart to the Saturn V. The largest of a family of launch vehicles that were to replace the ICBM-derived launchers then in use, the N series was to launch Soviet cosmonauts to the moon, Mars, and huge space stations into orbit. In comparison to Saturn, the project was started late, starved of funds and priority, and dogged by political and technical struggles between the chief designers Korolev, Glushko, and Chelomei. The end result was four launch failures and cancellation of the project five years after Apollo landed on the moon. Not only did a Soviet cosmonaut never land on the moon, but the Soviet Union even denied that the huge project ever existed. More...
