The plan is to combat stresses of space faced by the cosmonaut during space visit. However, during the initial trials, the experiment jeopardized the life of an astronaut hence it was put on hold for the time being but the recent successful trips to space insinuates that such quick trips might become useful and can be a standard for future travel to the ISS.
