The American space program officially beat the Soviets to the moon with the Apollo 11 landing in July 1969 but they hadn’t given up on many of their ambitious goals. One of these goals was realized in April 1971 when they successfully launched the world’s first space station – Salyut 1. The station’s development and construction was partially an outgrowth of their program for military stations which unlike the USAF’s cancelled plans continued well into the late 1970s.

Salyut 1 stayed in orbit successfully from April 1971 until October 1971 when, following the Soyuz 11 disaster, it was decided to de-orbit. There were two missions to the station – Soyuz 10 and Soyuz 11 – with Soyuz 10 achieving the first soft-docking with a space station and Soyuz 11 achieving the first hard-docking and first occupancy of a space station which lasted 21 days. A number of instruments, both publicly acknowledged civilian and highly secretive military, were used successfully during the 21-day occupancy. However the success of Soyuz 11’s mission was overshadowed by the terrible tragedy of accidental depressurization leading to the death of its three cosmonauts – Georgy Dobrovolsky, Vladislav Volkov, and Viktor Patsayev.

The Soviets hoped to return to Salyut 1 with a second occupancy and initiated the first orbital boost of a space station between July and August 1971. However the long redesign process of the Soyuz spacecraft would require additional orbital boosts, beyond the fuel capacity of the station, it would be nearly three years until another Soyuz crew visited a space station.

The Baruti 1, more formally the Baruti DOS-1, is an approximation of Salyut 1 and while designed for a crew of 2-3 it can act as a shelter for up to 8. It is designed to dock with a single Sangh 7K-OKS craft, typically with a crew of three, although any craft that uses the correct active docking port shouldn’t have any problem. It has extensive electric charge with two sets of solar panels making this a fairly simple long-term space station. The RCS is pretty simple and not meant for lengthy maneuvers but should be enough for easy rotation and orientation. The station also possesses a modified Sangh service engine module which provides about 200-300 dV for changing orbital parameters. It is recommended that you save most of the fuel to de-orbit the station but it can also be used for circularize your orbit or make small inclination changes.

The station’s launcher is modified from the available craft files and approximates the Proton-K launcher. However I’ve had to make a couple of changes to stabilize the ascent such as adding sets of stabilizer fins which weren’t on the actual Proton-K lifter. The ascent process can be a bit difficult as the lifter has a tendency to flip in the lower atmosphere so your angle-of-attack should be below 4 degrees and not include unnecessary rolls or pitch adjustments. It will be a fairly vertical ascent with the massive first stage being decoupled once you are in the upper atmosphere and having reached your desired apogee. The second stage will be more than enough for the rest of ascent and circularization and should be ejected upon reaching orbit. The third stage is somewhat optional but can be used to fix any mistakes in your initial orbit, further circularize your orbit or make last-minute burns to adjust your final orbit.

I recommend an orbit between 130 and 150km, similar to the historical parameters, although anything within LKO (Low Kerbin Orbit) should be manageable. If you plan on using my other craft such as the Sangh 7K-OKS then keep in mind its range. If you place the station too high in orbit you might have trouble successfully de-orbiting it.
