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.

SpaceX launched 60 more Starlink Internet satellites Wednesday aboard a Falcon 9 rocket. Liftoff from pad 39A occurred at 3:30 p.m. EDT (1930 GMT), and the Falcon 9’s previously-flown first stage successfully landed on SpaceX’s offshore drone ship.
