Relating to Mars Express: "At the same time, ESA’s Mars Express mission is continuing its investigations of Mars, painting a new picture of the 'red planet'. This includes the first ever probing below the surface of Mars, new geological clues with implications for the climate, newly-discovered surface and atmospheric features and, above all, traces of the presence of water on this world." |

I have another concern on ExoMars telecommunication capability since it will carry only UHF and it will be relying on American-European orbiters for the communications.
It is lacking the redundancy for any emercengy. I think ExoMars must bring another telecom equipment as a Low Gain Antena (Beacon Mode) in which it would be very useful for just in the case of any emergency that any orbibers are available or disponible for any reason. By incorporating the HGA would be much better but it is up to the ESA to evaluate about the benefits and costs. According to MER experience, the HGA was not very much utilized (less than 3% of cases). The additional weigth and cost will be compensated by the robustness of the mission. Rodolfo |
