"Requirements for the elements of building an extraction system:
fuel components of the second stage, non-toxic oxygen (oxygen-kerosene for the combustion engine, peri-hydrogen for the second stage combustion engine);
MTKS stages should consist of unified modules of the launch vehicle system with minimal modifications.
General requirements for the components and elements of the launch and return system are given in the relevant sections of the technical proposal.
2.2.2. The requirements for the ground-based support complex, in terms of determining the technical capabilities and costs of creating a ground-based complex, are as follows:
the ground complex should provide a program of 20-25 launches per year with a guaranteed period of reliable operation of 10 years;
the MTKS launch and landing complex must provide direct launching objects into synchronous solar orbits (i = 97-102) and orbits with an inclination in the range i = 51-63°;
two autonomous starting devices must allow parallel preparation and launch of two products;
the technical position must ensure the simultaneous assembly of two products;
The landing strip with dimensions of 5x0.1 km is located near the launch complex."
