Live coverage: Ariane 5 rocket launches TV broadcast satellites

A Vega rocket launched from French Guiana at 0149:24 GMT Tuesday (8:49:24 p.m. EST Monday) with Europe’s fifth Sentinel environmental satellite. The Sentinel 2B observatory will take the pulse of Earth’s vegetation, monitoring crops, forests, urban sprawl, and pollution from polar orbit.

Russia’s Proton rocket took off on its first launch of the year Sunday with a commercial satellite to expand Inmarsat’s next-generation mobile communications network. Liftoff occurred at 1231 GMT (7:31 a.m. EST), and it took more than 15 hours to place the Inmarsat spacecraft in the correct orbit.
