SpaceX Missions Section (with Launch Manifest and info on past and future missions) L2 SpaceX Section[2013] Inmarsat to purchase fourth Inmarsat-5 satellite from BoeingInmarsat has triggered an option to purchase a fourth Inmarsat-5 spacecraft under its existing contract with Boeing Satellite Systems International.
The programme schedule from Boeing has a satellite delivery date of mid-2016.
The fourth satellite will have a dual strategic role firstly, as an early available spare in the unlikely event of a launch failure of any of the first three Inmarsat-5 satellites.
...
Boeing will immediately begin construction of the fourth Inmarsat-5 satellite. The total cost of the option and certain related expenditure will be between US$220 million and US$250 million.
Inmarsat: The I5 SatellitesThe I-5 satellites, based on Boeings proven 702HP spacecraft platform, will deliver consistent high-performance download speeds of up to 50Mbps and up to 5Mbps over the uplink from their position in geosynchronous orbit. Their impressive statistics include:
The I-5 body at 6.98 metres (22.9ft), the height of a double decker bus
User beams 89 Ka-band beams generated by two transmit and two receive apertures
Spot beams six steerable spot beams to direct additional capacity where it is needed
Solar arrays a wingspan of 33.8 metres (111ft)
Solar panels five panels of ultra triple-junction gallium arsenide solar cells generate 15 kW of power at start of service and 13.8 kW by end of life
Station-keeping thrusters a xenon ion propulsion system (XIPS) handles in-orbit manoeuvring
Launch mass 6,100kg
Mission lifespan 15 years

Chopper on the live view. We have info they at pad clear/area secure, so heading into prop load next. Venting will be our sign of this being about 30 mins away.
Then we'll see the static fire. But we'll wait for the SpaceX tweet to call it as that only happens after the quick look review that the static fire was as required.
