[2013] Inmarsat to purchase fourth Inmarsat-5 satellite from Boeing (http://www.inmarsat.com/news/inmarsat-to-purchase-fourth-inmarsat-5-satellite-from-boeing-2//)
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 (http://www.inmarsat.com/the-i-5-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

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).

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.

Thanks to Steven, Zach and Chris - plus all the folks who chip in - with the coverage!

Per tradition. ONE POST EACH of congrats are allowed in this live thread (for nostalgia). All discussion and such go in the other threads.

Thanks again to the L2 members for paying for these amazing servers that allow us to cope with the massive demand of these launches.

Also, my own congrats! Per the pre-launch coverage and some reports from sources - and pending post launch review - this could be the cleanest mission yet! (No issues with the flow, LRR, etc. First time launch, etc.)

For us really a boring launch, which is a good thing for Space!!!  Thank's to NSF for the great coverage. Congrats to Inmarsat and good luck with the checkout. And big congrats to SpaceX. This is a level of proficiency that really shows off. I think that's just the way to sell rockets to customers with really expensive payloads!

SpaceX works hard... So it looks easy for us...
Pitty on the naked rocket, but getting a 6ton payload to GTO is no small feat for F9 !
Hope no more expendable first launches !
Cheers !

Even on an expendable launch (funny how strange this sounds already), they weaseled in some advancements; compacting the count by 10 minutes. SpaceX never misses an opportunity to continuously improve in every aspect of their operation. Great work!

Inmarsat press release:

Inmarsat confirms successful launch of the fourth Global Xpress satellite

16 May 2017: Inmarsat (LON: ISAT), the world’s leading provider of global mobile satellite communications, has confirmed the successful launch of the fourth, high-speed broadband communications satellite in its transformational Global Xpress (GX) constellation.

Inmarsat GX is the world’s first globally available, broadband connectivity service and was created to enable communities across the world to benefit from the emerging digital society.

Inmarsat-5 F4 (I-5 F4) was launched by SpaceX on a Falcon 9 rocket at 00:21 (BST) / 19:21 (ET) from the historic launch pad 39A at NASA’s Kennedy Space Center in Florida. Following satellite separation at 00:53 (BST) / 19:53 ET, we acquired telemetry from our Perth ground station at 01:04 BST / 20:04 ET.

The launch team from Inmarsat and Boeing Network & Space Systems, the manufacturer of I-5 F4, are now raising the spacecraft to a geostationary orbit, at which point the satellite will deploy its solar arrays and reflectors, and undergo payload testing.

I-5 F4 joins the three GX satellites already in orbit, which have, since December 2015, been delivering unprecedented service speeds, global coverage, reliability and security to users on land, at sea and in the air.   The fourth satellite adds further capacity to the GX network, as well as in-orbit redundancy that further upgrades the reliability and resilience of Inmarsat’s service offerings.

“For Inmarsat, reliability and resilience are paramount,” said Rupert Pearce, CEO, Inmarsat. “Delivering global commercial services over the GX network, which we achieved at the end of 2015, was only the start of our Global Xpress project.  I-5 F4 augments the capabilities of GX and, alongside our existing L-band constellations, enables Inmarsat to provide guaranteed global connectivity to industries and governments worldwide.

“I would like to thank all my colleagues at Inmarsat, whose hard work and dedication is seeing Global Xpress setting a new standard of excellence for broadband communications in established VSAT markets, such the maritime and government sectors, while also rapidly gaining strong traction in new market areas, such as the rapidly expanding aviation passenger connectivity sector.

“I also wish to extend my sincere thanks to our satellite manufacturing partner Boeing and our launch partner SpaceX for delivering a successful launch outcome.”

Boeing-Built Satellite Will Enhance Global High-Speed Broadband Network

Fourth and final Inmarsat-5 satellite adds further capacity and coverage to the Global Xpress network


EL SEGUNDO, Calif., May 16, 2017 – The fourth Boeing [NYSE: BA] Inmarsat-5 satellite, which was launched yesterday, will noticeably expand the high-speed broadband service available through Inmarsat’s Global Xpress network after the satellite becomes fully operational later this year.

The Inmarsat-5 satellites are uniquely able to provide seamless communications coverage through fixed and steerable beams that can be adjusted in real time to accommodate demand surges.     

“Inmarsat-5 F4 joins our existing Global Xpress constellation, which is already being adopted as the new standard in global mobile broadband connectivity by companies, governments and communities around the world,” said Michele Franci, CTO, Inmarsat. “Boeing has been an outstanding partner in our journey to make Global Xpress a reality.”

This is the fourth Inmarsat-5 satellite Boeing has built for Inmarsat’s Global Xpress network. After reaching its final orbit, the satellite will undergo testing and checkout before being declared operational. 

“Our partnership with Inmarsat has enabled the creation of the world’s only commercial global, mobile Ka-band network,” said Mark Spiwak, president, Boeing Satellite Systems International. “This unique achievement is an example of Boeing’s continuing commitment to deliver reliable, affordable and innovative solutions for our customers.”

Boeing has a strategic marketing partnership with Inmarsat and currently provides both military Ka-band and commercial Global Xpress services to U.S. government customers.

Do not confuse the publication of TLEs with the detection of maneuvers.  It can take a while to collect enough observations and fit an element set that is of high enough quality to be published.  *Sometimes* the flyers of the satellite will announce successful maneuvers (like ISRO does) long before a TLE gets published....
