SpaceX’s Falcon 9 rocket carried a satellite into orbit early Tuesday morning, marking a milestone 50th launch for the company’s workhorse rocket.

The six-ton satellite is set to improve television, broadband, and telecommunications services in Europe and Northwest Africa, and it was “almost the size of a city bus,” as Elon Musk tweeted, adding that it’s the largest geostationary satellite his company has ever flown.
