[2013] Inmarsat to purchase fourth Inmarsat-5 satellite from Boeing
Quote
Inmarsat 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 Satellites
Quote
The I-5 satellites, based on Boeing’s 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

Now the NROL-76 mission has launched, next up will be this one.

Per L2 KSC Schedule, the Static Fire is currently NET May 11. This is - as always - pending post launch 39A Pad shakedown report (required to check if any repairs are required ahead of the next rocket heading to the pad).

You want to be inspired by things. You want to wake up in the morning and think the future is going to be great. That's what being a spacefaring civilization is all about. It's about believing in the future and believing the future will be better than the past. And I can't think of anything more exciting than being out there among the stars.

All quiet on this one, but as of latest, everything is still holding towards the Static Fire on May 11.

39A Shakedown Report was great again.

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.
