Next Ariane 5 mission - Launch of T-16 and EUTELSAT 7C satellites - ICARE-NG instrument set to fly on CARMEN-4 mission

On the night of Thursday 20 and Friday 21 June, Ariane 5 will be sent aloft from the Guiana Space Centre (CSG), Europe’s spaceport in Kourou, carrying the T-16 satellite for AT&T and the EUTELSAT 7C satellite for Eutelsat. The launch will mark Ariane 5’s 104th flight, the 71st with the ECA variant, its second in 2019 and the fifth of the year from the CSG.

With a launch mass of 6,330 kilograms, T-16 was built by Airbus Defence and Space. It will provide high-power broadcast services and great operational flexibility from five orbital slots, covering the continental United States, Alaska, Hawaii and Puerto Rico. The satellite has an expected lifetime of 15 years.

With a launch mass of 3,400 kilograms, EUTELSAT 7C is a high-power telecommunications satellite built by Maxar Technologies for markets in Africa, Europe, the Middle East and Turkey. The satellite has an expected lifetime of 15 years.

As part of efforts to develop flight experiments to measure Earth’s radiation environment, CNES has been working for close on 30 years on international cooperation agreements to carry radiation monitors on satellites. The CNES-Eutelsat cooperation agreement signed in 2016 provided the framework to fly the ICARE-NG instrument on EUTELSAT 7C. This mission, named CARMEN-4, seeks not only to measure the space environment in geostationary orbit but also and above all to characterize it throughout the orbital positioning phase using the satellite’s electric thrusters each time it crosses the radiation belts. This unprecedented experiment will improve spatial coverage of spectrometry data on proton and electron fluxes.
