SES switches SpaceX and Arianespace launches to mitigate cost of satellite failure
by Peter B. de Selding | Aug 28, 2017
PARIS — Satellite fleet operator SES, which this year has suffered both predictable satellite-launch delays and unpredictable satellite failures, on Aug. 28 said it would move a satellite from launch-service provider SpaceX to Arianespace to minimize revenue losses.
As a result, the SES-14 satellite will launch aboard an Ariane 5 ECA rocket early in Q1 of next year rather than a less-clear Q1 launch date offered by SpaceX. SpaceX instead will launch the heavier SES-12 satellite, up to now slated for an Ariane 5, on a Falcon 9 vehicle in Q1 2018.

[The Jakarta Post] Telkom to replace troubled satellite in August 2018State-owned telecommunications company PT Telekomunikasi Indonesia (Telkom Indonesia) plans to launch its Telkom 4 satellite in a year’s time to replace the troubled Telkom 1.
“We have signed a contract to launch the Telkom 4 satellite. It will be launched from the United States in August 2018,” said PT Telkom president director Alex J. Sinaga during a press conference with Communications and Information Minister Rudiantara in Jakarta on Wednesday.

Does anyone know,
Which one of Spaceflight flights is the one with Space IL, and what is the chance for that to launch on time for the Xprize?
Guess they are still with SpaceX, maybe on the Spaceflight GTO rideshare?
[Space.com] Calling the Moon: Startup to Put Cellphone Tower on the Moon PT Scientists has a launch contract for late 2018 with Space X as a secondary payload on the Falcon 9 rocket. Becker said the company believes it will be the first private entity to reach the surface of the moon, suggesting that none of the Google Lunar X Prize participants are likely to meet the December 2017 deadline for the competition. (PT Scientists itself withdrew from the Google Lunar X Prize earlier this year due to the time constraints of the competition.)
The Falcon 9 will carry the team's spacecraft, Alina, to the geostationary transfer orbit, a highly elliptical Earth orbit whose highest point is 26,000 miles (42,000 kilometers). From there, Alina will continue on its own to the moon.

Tweet from Jeff Foust:Kacific announces that it’s selected SpaceX to launch its Boeing-built Kacific-1 broadband satellite on a Falcon 9 in 2019.
Kacific selects SpaceX to provide launch service
Kacific Broadband Satellites Group (Kacific) has selected SpaceX as the launch provider for its Kacific-1 satellite, which is being built by The Boeing Company.
Kacific-1 will be launched on a SpaceX Falcon 9, a two-stage orbit-class rocket designed from the ground-up for maximum reliability and reusability.
“SpaceX has a breadth of vision that appeals to us,” says Christian Patouraux, Kacific CEO. “The company is committed to changing the way people think about space and the possibilities it represents. Signing with SpaceX as our launch service provider is a major step towards delivering our own vision. We look forward to seeing Kacific-1 atop a Falcon 9 Rocket in 2019.”
“SpaceX is proud to partner with Kacific on the milestone launch of the company’s first satellite, Kacific-1.” said Gwynne Shotwell, President and COO of SpaceX. “We appreciate their confidence in our proven capabilities and look forward to delivering their satellite to orbit.”
In February 2017 Kacific placed an order with The Boeing Company for the Kacific-1 satellite. Based on the reliable 702 satellite platform, Kacific-1 is designed to deliver high speed broadband via 56 narrow Ka-band beams, with the most powerful signal level ever achieved in a commercial satellite in the South East Asia and Pacific regions.
About Kacific
The Kacific Broadband Satellites Group is a satellite operator developing a high-speed broadband offering for underserved, remote and rural markets with disseminated pockets of population. It addresses the gap in supply with specifically designed satellites using the latest multi-beam and high throughput space communications and ground technology transmitting over the Ka Band.
Using cost-effective technology and a lean business model Kacific aims to provide better broadband quality at significantly less than current retail prices, fostering greater internet usage and fuelling economic growth and improvements in service delivery across covered regions, with its first deployment focusing on South East Asia and the Pacific.
Kacific’s headquarters are in Singapore with main operations out of Vanuatu.

So, at least four GTOs recently added... possibly five, plus Kacific this week.
Must be making impression on the market that backlog is under control.

If the four or five you're referring too are the ones Skyrocket listed, only the Sirius flights are really new.

Telkom-4 is this year (we heard about it a few months ago). PSN-6 (SSL) we've known about for over a year. Eutelsat is one of those old contracts that's never been assigned a firm payload, speculation was it would be the Eutelsat Quantum satellite but apparently there is political pressure to launch that one on a European rocket since it has government funding.
edit: the Eutelsat contract was from early 2016 for either Quantum or something else...

I guess it was good planning on SpaceX's part to not have another launch planned at the Cape for a month.

Do we have any idea when the SXM-7 and SXM-8 launches were awarded to SpaceX or the potential value? Just a surprise to see these going on a Falcon 9 since previously they've only launched on a Zenit or Proton vehicle.

I know you meant it as a joke, but September is the peak of the hurricane season. Maybe this factored into the mission planning.

It would be interesting to know what fraction of the critical path through September was allocated to: expected weather disruption (check!), Hawthorne/McGregor work (unaffected), or Cape work (likely to be delayed).

Here is the math.
Using Blk 5's that have flown only in 2018, and that only BLk'5 will fly in 2018.
That each Blk 5 will be capable of 3 flights 1 as new and 2 as used without much refurbishment work. Mostly just inspections and tests, little or no hardware swap-out.
That the initial quarter of 2018 (2018 Q1) launches 4 new Blk'5. The build rate of 1st stages remains at 4 per quarter. The build rate of US starting in 2018 is increased each quarter until reaching a build rate of 12 per quarter by 2018 Q4.
Then by EOY 2018 there will have been 32 launches, with 67% of then in the last quarter being used. This used to total rate will become steady state such that a total of 48 launches is possible in 2019.
This is without requiring more manufacturing floor space.
By decreasing the 1st stage build rate to 3/quarter and increasing the US build rate to 16/quarter. By increasing the re-flight rate for each booster by 1 to 1 new and 3 used flights for a total of 4, enables a total number of launches per year of 64 also without the need for more floor space. The used to total flights rate will then be 75%.
