That came the apparent end of the mission, Dawn, the probe is simply lost in the pile asteroids
NASA has lost contact with the Dawn space probe, it`s just silent, maybe out of range or has long been out of order. Engineers from NASA repeatedly tried to contact the probe, but all attempts were at least not successful, after analyzing the situation, the conclusion was drawn, with a high degree of probability, experts believe that the device does not communicate due to the lack of on Board the proper supply of fuel that it needs in order to keep the antenna in the right direction. Probably the probe is flying somewhere, but the contact with the Ground he can not, because he is not able to send and adjust the direction of the antennas towards the ground station tracking. No directional antenna, there is no communication. Perhaps there is another reason, some experts believe that the Board has run out of batteries, and solar panels do not work for any reason. Could be damage from the outside, it may be purely a technical failure, and it may be all right, and there`s no fuel to turn so that the panel was in the area of illumination of our Sun.
If we talk globally, the completion of NASA`s Dawn mission means only one, the mission ended with the onset of November 2018. It was possible to study two quite interesting objects from the asteroid belt, but the larger mission was not enough.
Tracked and controlled the probe through a network of ground antennas Deep Space Network NASA, the last session was October 31 and then everything stopped. Although NASA likes to give away secrets to the left and to the right, but the fact that engineers believe the reason for the lack of communication with the probe seems to be more true than fiction. According to NASA`s probe Dawn has completed the inventory of hydrazine. All the fuel that was on Board has already been spent, so that`s it, the mission even according to NASA ended. NASA`s mission Dawn is considered quite successful, because it has successfully worked for a period of 11 years, was able to deliver a lot of information to scientists about two large bodies in the asteroid belt. Between Jupiter and Mars there is a belt with asteroids, and there the probe studied the dwarf planet Ceres, by the way, its orbit and now he is spinning, there he hung for the rest of the time. In addition to Ceres, the asteroid studied and West, scanned the surface of these two huge bodies of the asteroid belt, now scientists have a very large layer of information on the asteroid belt in the Solar system. Perhaps it will give some impetus to the knowledge of all that surrounds us in the near space Can be on the basis of new discoveries by scientists a hundred and even assume that something that in principle even the head will not wear. But in any case, everyone is happy, the probe worked 100% well and went to honors.
Launched the Dawn device back in 2007, before the first volume of work the probe flew 6.9 billion kilometers. On Board the probe was installed the most fashionable at the time the ion engine, largely thanks to modern technology probe during the set many kind of records. First of all, we can say that the Dawn probe is the first artificial satellite in the orbit of Ceres. This is not the smallest asteroid in the asteroid field, it ate the size of almost a small planet. The second record or achievement can be considered that the probe visited two large objects in the asteroid field. In NASA on what the consider, that on Ceres can be find life and apparently for this reason its so courting. And apparently for this reason, pulled his dying probe as far as possible from the surface. Now, in the absence of fuel, the probe will fly for decades in orbit around the dwarf planet, but all this will not be eternal and when it still falls to the surface and fill it with man-made fragments.
