    Orlan-MK can operate in a vacuum and withstand huge fluctuations in temperature for up to seven hours. It is equipped with a built-in cosmonaut rescue system. Special engines help the cosmonaut to return to the space station in the event that he drifts away. 
    There are just six space suits of this model. They have a service life of four years, after which they need to be replaced.
