OS-M
OS-M is the name of a range of launch vehicles from the Chinese space company OneSpace . It also stands for the smallest of these missiles, also known as the OS-M1.
background
OS-M is one of many small satellite launch projects that have emerged since the Chinese space market opened to private capital in 2014. The private providers are supported by technology transfer from the state space industry.
OneSpace was founded in 2015 and initially developed the suborbital rocket OS-X.
Models
OS-M (OS-M1)
The OS-M - also called OS-M1 to distinguish it from the model series of the same name - is a four-stage rocket with solid propulsion engines . It is 19 meters high and is supposed to bring satellites weighing up to 200 kg into low earth orbit (LEO). OneSpace specifies the possible inclination of the track at 42–100 °. There are two different sized payload fairings to choose from.
So far, the rocket has only completed one unsuccessful flight: It took off from the Jiuquan Cosmodrome on March 27, 2019 and, after the first stage was disconnected, went into a tailspin because the attitude control of the second stage did not work due to a defective gyro instrument .
OS-M2
The OS-M2 is still under development. It is based on the OS-M, but also has two side boosters . This increases the LEO payload capacity compared to the OS-M to around 500 kg. There are two versions with differently strong boosters ("Type A" and "Type B").
OS-M4
As the most powerful model, the OS-M4 is equipped with four cross-shaped side boosters, also in versions A and B. OneSpace specifies the maximum payload for low orbits at around 750 kg.
