Space expeditions will fly to the Mars in fifteen years if all prerequisites are successfully met. For the future interplanetary expedition Moscow scientists have developed an efficient system to protect the crew from space radiation during the long-term travel to the Mars and back. Russian scientists have designed automated systems of radiation control and safety for the Martian expedition. During this expedition a lot of things will be executed for the first time, e.g. a complicated sensor system, controlled by the on board computer, will protect the cosmonauts from the destructive space radiation.
