At present, RSC Energia has developed a conceptual configuration for the interplanetary orbiter where the crew will work during the entire interplanetary transit. This incorporated the experience of work on space stations.

Based on the analysis of failure statistics for those space stations, a concept was developed for the functional and unit redundancy needed to assure a high level of reliability of the orbiter. Layout of Interplanetary orbiter sections

Модуль-М (42 325 bytes)The first experimental spacecraft (Module-M) is to be delivered to ISS on-board Progress spacecraft, to be subsequently assembled by the crew during an EVA and moved away from the space station. Using electric propulsion main engines, the spacecraft will raise its orbit to 1200 km. This mission will study the effects of long operation of electrical propulsion engines on the equipment.
At present, Energia's manufacturing plant has built the spacecraft structure, virtually all the mechanical units and assemblies have been tested, and the spacecraft support systems and scientific payloads have passed the phase of developmental testing in the lab. However, since the funding for this work has stopped, manufacturing of further elements for the spacecraft is suspended.
The next spacecraft, Module M2, is to be sent to a Lagrangian point (H= 1,500,000 km). Along with developmental testing of solutions to fundamental problems of the interplanetary vehicle flight, this spacecraft is also to be used for early warnings of magnetic storms on Earth caused by the solar activity.
And, finally, Mars-Module is to be sent to Mars to study the planet. It will be the first spacecraft, which, along with the developmental testing of the interplanetary vehicle will be intended for Martian research using remote sensing equipment and landers with the necessary equipment, which it will deliver. It will support the operation of the equipment in Mars orbit for more than two years. If need be, this spacecraft will be capable of returning to low Earth orbit.
Mars-Module will be capable of addressing the following Mars research tasks:

  • Study of Mars climate, surface and internal structure;
  • Global photographic survey of the Martian surface;
  • Mars remote sensing.

A main feature of the series of spacecraft for developmental testing of the interplanetary vehicle is that they will be de3livered to ISS on-board Progress spacecraft to be assembled by the space station crew.
