Launch Details
The Inmarsat-6 F1 launch took place on Wednesday, December 22, from Japan's Tanegashima Space Center at 10:32 a.m. EST (1532 GMT).
The satellite was launched aboard a Mitsubishi Heavy Industries H-2A rocket.
The Inmarsat-6 F1 is the first of two "I-6" spacecraft that London-based company Inmarsat plans to loft to geostationary orbit, about 22,240 miles (35,790 kilometers) above our planet.
The satellite weighs 12,060 pounds (5,470 kilograms).
Wednesday's launch had originally been targeted for Tuesday, but concerns about possible bad weather caused a one-day delay.
The I-6 pair "are the largest and most sophisticated commercial communications satellites ever launched", Inmarsat representatives wrote in a fact sheet.

Mission and Destination
The Inmarsat-6 F1 satellite has a destination of Geostationary Transfer Orbit. This satellite is part of a dual mission to augment both L-band and Ka-band Global Xpress services.
Inmarsat-6 F1 is the first of two "I-6" spacecraft that London-based company Inmarsat plans to loft to geostationary orbit, about 22,240 miles above our planet. It's a huge satellite, weighing in at 12,060 pounds.
The Inmarsat-6 F1 satellite will be compatible with existing terminals for Inmarsat's already-operational ELERA and Global Xpress networks. This means that users won't need to worry about upgrading their equipment to use the new satellite.
The Inmarsat-6 F1 satellite carries a large 9 m aperture L-band antenna and nine multibeam Ka-band antennas. This setup provides a high level of flexibility and connectivity for users.
