From the beginning accuse succumbed to a slip in the product controlling the Fregat's trajectory. Be that as it may a review of the flight parameters elucidated the circumstances: the two mentality control thrusters — little thrusters that keep the shuttle and its impetus motor pointed in the right heading — neglected to flame when they needed to. "At the point when an engine capacities, and afterward quits working, it implies that the fuel is no more getting there," says Mario de Lépine, a representative of Arianespace, who controlled the dispatch.
The fuel — hydrazine — didn't achieve the thrusters on the grounds that it solidified in its sustain line, which was so close it would have been impossible an alternate food line convey fluid helium. Both lines were mounted on a same help structure that, lamentably, worked as a warm scaffold cooling the hydrazine. The shortcoming has likewise been found in other Fregat arranges that are presently under development in Russia, and was obviously brought on by ambiguities in the outline records of Fregat.
An Independent Inquiry Board proclaimed the disclosure of the issue at a gathering on 7 October at the Arianespace Headquarters in Evry, close Paris. The shortcoming is effectively remedied, and Stéphane Israël, Chairman and CEO of Arianespace, said after the gathering that he expects that its effect on the Galileo system will be little. "We are taking a gander at the resumption of Soyuz dispatches from Guiana Space Center as right on time as December 2014."
However space engineers at the European Space Agency (ESA) aren't not excited for the following dispatch to be to soon, says ESA representative Dominique Detain. One of the reasons is that the two satellites, stranded in wrong circles, can at present acquire back the cost of 150 million euro (US $190 million). "We are attempting to recuperate the mission by doing tests on all their frameworks — to the extent that we can — to perceive how these satellites carry on in space," says Detain.
"In the event that we find something the issue with the satellites, this could likewise be a deficiency in alternate satellites. It is better to hold up, until we have the affirmation that everything works, or we have data that something must be altered, before sending up alternate ones," says Detain.
The timing of the following dispatch will be chosen in the following few weeks. There are additionally more alternatives. "The following dispatch will comprise both of two satellites propelled by a Soyuz, or four satellites with an Ariane-5
