Congrats on a successful expendable F9 mission.
Keep up the consistent good work and robust design as you continue to deliver launch services at the lowest prices and with the most-accessible manifest of all launch service providers globally!

Congratulations to SpaceX, Inmarsat, and the range guys. Never boring for me!
The number of commerial Falcon customers is gradually overtaking the government ones- a sign of a very healthy program, IMO.

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.”

Never boring - I'm always anxious during any launch; manned or unmanned.

42699 FALCON 9 R/B 2017-025B 1410.43min 24.47deg 70181km 384km
I believe these are identified backwards: the payload is in the 384 x 70,181 km orbit; and the Falcon-9 upper stage rocket body is in the 381 x 69,839 km orbit. Expect 18 SPCS to swap these in the next couple of days.

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.

Roughly a 1,570m/s deficit to GEO. That's almost Zenit-3SL/Proton-M/Briz-M performance.
