Before October 2003 there had only been two nations capable of independently sending manned missions into space, the United States and the Soviet Union/Russia, but all of that changed with the success of Shenzhou 5 and its astronaut (or taikonaut dubbed by some), Yang Liwei. The Chinese space program either began in March 1956 with the beginning of its ballistic missile program or in 1958 when Mao Zedong declared that for the PRC to be taken seriously as a super power it would have to launch its own satellite. It wouldn’t achieve this until 1970 with the launch of Dong Fang Hong (The East is Red 1), and the manned program didn’t start earnest development until the mid-1990s. The Shenzhou spacecraft remains the only manned vehicle of the program, with variants and modifications depending on the mission, and is vaguely related to the Soyuz spacecraft. It was launched by another staple, the Long March 2F rocket which was partly based on Russian technology and stretched back to the original rocket from the early 1970s.

The Khi SZ 2-5-7 is a basic approximation of the Shenzhou spacecraft as flown for the Shenzhou 5 while incorporating some features from Shenzhou 6 and 7. Much like its real-life counterpart it has a number of similarities to the Soyuz/Sangh spacecraft with a number of key differences. The most important is that its orbital module can be detached and operated independently, albeit in a limited fashion. The descent module carries two kerbonauts and the orbital module only carries one so it can’t be used as any kind of emergency shelter per se. However the orbital module has its own monopropellent thrusters, electric capacity, and solar panels so a single kerbonaut could technically survive in orbit and be rescued later. The orbital module isn’t equipped with a front-facing docking port so the combined craft can’t be docked with another spacecraft.

Most of the other functions of the Khi SZ 2-5-7 are fairly basic and can be used for any number of LKO (Low Kerbal Orbit) missions. I have left it with full liquid fuel and monopropellent tanks which far exceed its intended mission parameters. This was done for weight balance issues during ascent but should still be fine if you want to reduce the amounts for a more intended mission. I would recommend leaving yourself with about 300-400 dV in the service module and to leave the monopropellent in the orbital module alone.

The Khi II launcher is based on the Long March 2F rocket used as the lifter for the Shenzhou spacecraft. It is similar in a fashion to the Soyuz R7-derived launcher in that it has a booster stage which is fired along with the main stage. The combined booster and main stages should put you into the upper atmosphere nearly to the edge of stage. The boosters will exhaust themselves first and are decoupled not long before the main stage is also exhausted. The much smaller second stage will finish out the ascent and handle orbital circularization.

Once your mission is completed you can end it several different ways witht he Khi SZ 2-5-7. The first is to simply burn to retrograde and decouple the service module and orbital module upon reaching the atmosphere. They will be destroyed during re-entry and the descent module will open its parachute in the lower atmosphere. Another procedure could be to undock the orbital module and leave it as an unmanned probe in orbit. Since it has its own independent systems and a few instruments it could be visited by future missions. The rest of the spacecraft will still function without the orbital module especially if it’s about to land.

Built in the VAB in KSP version 1.3.0.
