The Metop-C./ DR satellite
A Soyuz rocket that departed from Guyana on Tuesday night has successfully "placed" Metop-C into a polar orbit, a meteorological satellite for Eumetsat, the European body responsible for the development of satellite weather systems, Arianespace said in a statement.
Soyouz was torn from the ground at 9:47 pm on Tuesday (1 am 47 Wednesday in Paris), for the 19th time since his shooting point in the town of Sinnamary northwest of Kourou. The rocket then followed a trajectory that was qualified as "nominal". The separation of the satellite took place as planned a little over an hour after takeoff.
Metop-C is the third and final satellite of a program devoted to applied meteorology, according to Arianespace. Metop-A and Metop-B, launched by Starsem from Baikonur in Kazakhstan, respectively in 2006 and 2012, are still operational, the company said the markets on the market.
Developed and built by Airbus Defense and Space
Metop satellites contain weather forecasts from 12 hours to 10 days in advance.
The mission of Metop-C, developed and built by Airbus Defense and Space, will "strengthen, optimize and complement the capabilities of the two other satellites in the series," Arianespace said.
With a total take-off weight of just over 4 tons, Metop-C, designed to work five years, will have a runway that goes through the poles at 811 kilometers altitude with nine instruments on board including French IASI.
This instrument "measures, in addition to the temperature and humidity of the atmosphere, more than 25 atmospheric components with great precision and participates in monitoring the climate", the National Center for Space Studies (CNES) indicated.
"With the launch of this third and final EPS satellite (Eumetsat Polar System), Arianespace is helping Eumetsat and Europe once again to improve global weather forecasting and climate monitoring for a better future, living on earth," Arianespace said in a statement at the end of the mission.
The previous launch of a Soyuz rocket ended in failure
This launch is the eighth of the year for Arianespace in French Guyana and the second in 2018 with the Soyuz launcher since the local Sinnamary field. At this stage of eight launches since the beginning of the year, 50% of the Arianespace launches were made in favor of the commercial market, the other half for European institutional partners, according to the company.
The previous launch of a Soyuz rocket from Baikonur on 11 October failed.
The flight to the international space station Nick Hague and Alexey Ovchinin was stopped two minutes after takeoff and caused the automatic ejection of the capsule with the two men.
According to the findings of the Committee of Inquiry, announced last Thursday, the failure caused by the accident is due to a "deformation" of a sensor during the assembly of the missile in Baikonur.
