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 originally modified from the available craft files and approximates the Proton-K lifter. The thrust-to-weight ratio is fairly low which may make the initial ascent rather difficult and cumbersome. I highly recommend keeping an angle-of-attack of 5 degrees to avoid accidentally flipping the entire thing. The massive first stage should get you into the upper atmosphere after which the second stage will complete the ascent. The vessel should be more controllable upon decoupling of each stage. I also recommend deploying the fairings upon reaching space so you can use the space station’s RCS for finer control with your orbital burn. The orbital burn can be handled either by the remains of the second stage, unless its already been used by the ascent, or by the third stage which is easier to control.

The historical Salyut 1’s orbit changed a number of times so a historical approximation can be anywhere from 130 to 220km but depending on your inclination any LKO (Low Kerbin Orbit) should be manageable. You should also factor in the abilities of the manned spacecraft you intend to dock with the station. You may also encounter problems successfully de-orbiting the station if your altitude is too high.

Built in the VAB in KSP version 1.4.3.
