The possibility of using a cable system placed on a near-Earth orbital station for a flight to Mars is considered. A comparison of the fuel costs of two options for departure to Mars is carried out. The first option is provided for a normal departure from a reference circular near-Earth orbit two hundred kilometers high. The second option assumes a preliminary flight from the reference orbit to the orbital station. After docking with the orbital station and deploying the cable system, the launch is carried out from the upper platform of the cable system relative to the Earth. The orbital station is moving in a circular orbit with a height of four hundred kilometers. It is shown that for cables made from real materials, fuel economy can reach 70%. But this result is possible only in the case of a one-time use of the cable system. If one wants to use the cable system repeatedly, then they need to take into account the additional fuel costs for restoring the initial orbit of the cable system. In order to preserve the initial position of the center of gravity of the cable system, it is proposed to separate the second spacecraft from the lower platform of the cable system simultaneously with the separation of the spacecraft from the upper platform, with its further descent to the Earth. The results of calculations of the gain in fuel consumption are given.
