SpaceX successfully launched an Inmarsat-5 F4 communications satellite into orbit on a Falcon 9 rocket on Monday, May 15.

The Inmarsat-5 F4 is the fourth and final communications satellite sent into orbit to support the London-based Inmarsat company’s Global Xpress network, which delivers broadband support across the planet. The Inmarsat-5 F4 satellite weighed 13,380 pounds, nearly all of the Falcon 9 rocket’s full capacity, according to NASA Spaceflight.
