Satellite fleet operators Telesat of Canada and APT Satellite Co. Ltd. of Hong Kong have agreed to divide the cost of a new satellite to replace their jointly owned Telstar 18/Apstar-5 at 138 degrees east, with the successor, called Telstar 18 Vantage/Apstar-5C, to be built by Space Systems Loral and launched in early 2018.The satellite will carry 63 C- and Ku-band transponders, including both regional Ku- and C-band beams and a high-throughput (HTS) Ku-band payload. It will be Ottawa-based Telesat’s third Ku-band HTS-equipped satellite...In a Dec. 24 statement to the Hong Kong Stock Exchange, APT said it would be paying a London-based subsidiary of Telesat a total of $118.83 million for a 57.47 percent share of the satellite’s resources, which the company said is equivalent to 36.2 transponders. The satellite will be capable of generating 14 kilowatts of power to its payload at the end of its service life of more than 15 years.
18/08/2017As of Aug 2017, the construction of the APSTAR-5C satellite has made significant progress. System CDR was conducted successfully in September 2016, the result showed the performance of the satellite is in line with specifications. Currently the satellite has entered into the AIT (assembly, integration and test) phase, mating process of SM (service module) and CM (communication module) has been conducted successfully. Installation and testing for each subsystem is under way.Current schedule shows that APSTAR-5C will be ready for shipment in the first half of 2018, then be launched by SpaceX’s Falcon-9, and replace the in-orbit APSTAR-5 satellite in the second half of 2018. Through APSTAR-5C, we will be able to maintain highly reliable services for our existing customers on APSTAR-5 satellite, assuring their businesses not be interrupted by the replacement. Meanwhile, APSTAR-5C satellite will carry more transponders, and expand to broader service areas, especially its high-throughput (HTS) capacities will satisfy growing market demand in Southeast Asia.
FOR IMMEDIATE RELEASE (From SSL)June 21, 2018Maxar’s SSL ships first of three advanced communications satellites scheduled to launch on the SpaceX Falcon 9 this summerCommercially driven advances help SSL customers to connect people and transform lives around the worldPalo Alto, Calif. – SSL, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.) (NYSE: MAXR, TSX: MAXR), today announced it shipped the first of three satellites that SSL will deliver to the SpaceX launch base at Cape Canaveral Air Force Station in Florida over the next month. Driven by commercial advances, the three satellites will bring communications capability to connect people and transform lives around the globe.Telstar 19 VANTAGE, an advanced high throughput satellite (HTS) built for Telesat, one of the world’s leading satellite operators, marks the 50th SSL-built communications satellite to launch this decade. It arrived safely at the launch base this week for a launch scheduled next month.Two more SSL communications satellites are scheduled to ship to SpaceX launch base over the next month including a second HTS for Telesat, Telstar 18 VANTAGE, and the Merah Putih satellite (previously known as Telkom-4), for Indonesia’s largest telecommunication and network provider, PT Telkom Indonesia (Persero) Tbk.“SSL has a long legacy of leveraging its commercial mindset to provide satellite operators with spacecraft systems that address their requirements and enable global transformation,” said Dario Zamarian, group president, SSL. “The cadence this month of shipping out three satellites for launch demonstrates our ongoing market leadership and commitment to quality, reliability, and performance.”Telstar 19 VANTAGETelstar 19 VANTAGE is one of a new generation of Telesat spacecraft designed to serve today’s bandwidth intensive applications. It will support a range of services, including advanced broadband connectivity for consumer, enterprise and mobility users across the Americas and Atlantic from its prime orbital location of 63 degrees West, the same location used today by Telesat’s Telstar 14R. Like all Telesat VANTAGE satellites, Telstar 19 VANTAGE combines broad regional beams and powerful HTS spot beams enabling customers to maximize throughput and spectral efficiency while optimizing network performance. Its Ka-band HTS capacity will serve Telesat customers operating in Northern Canada, the Caribbean, the North Atlantic Ocean, and South America. Additional Ku-band HTS spot beams will serve growing South American markets in Brazil and the Andean region. Telstar 19 VANTAGE will also bring new Ku-band broadbeam capacity over the North Atlantic Ocean enhancing Telesat’s coverage of this important mobility market. Telstar 18 VANTAGETelstar 18 VANTAGE, the third HTS in Telesat’s global fleet, will be located at 138 degrees East, an ideal position for connecting Asia to the Americas. It will replace and expand on the capabilities of Telesat’s Telstar 18 satellite through its extensive C-band coverage of Asia, its Ku-band HTS spot beams over Indonesia and Malaysia, and its six additional Ku-band regional beams. These high performance beams will enable Telstar 18 VANTAGE to meet growing demand for mobility, enterprise networks and telecom services across the Asia region. As previously announced, Telesat has partnered with APT Satellite of Hong Kong in the design and procurement of this spacecraft, which APT calls Apstar-5C. “Telesat has worked closely with SSL and the Maxar family of companies for many years and we are pleased to have collaborated with them on our newest Telstar VANTAGE high throughput satellites,” said Dan Goldberg, President and CEO of Telesat. “These state-of-the-art spacecraft are going to provide important competitive advantages for our customers across the Americas and Asia. It’s great news that Telstar 19 VANTAGE is now at the launch base and that Telstar 18 VANTAGE is nearly finished and in the queue to ship.”Merah PutihMerah Putih, a name which represents the red and white of the Indonesian flag, will be integrated into Telkom’s greater telecommunications network to provide service throughout the 17 thousand islands of the Indonesian archipelago, as well as India and other parts of South and Southeast Asia. Satellite forms the telecommunications backbone that connects Indonesia, along with other technologies, such as submarine cable.Merah Putih, which was completed ahead of schedule, will replace Telkom-1, at 108 degrees East, where it will expand on Telkom’s coverage to serve new markets. Its all C-band payload will enhance both internet and telephone service for populations in remote regions and offload backhaul for cellular service.“Satellite plays a vital role in our telecommunications infrastructure,” said Mr. Mr. Zulhelfi Abidin, Chief Technology Officer of Telkom. “SSL has been an excellent spacecraft supplier and has completed the satellite construction ahead of schedule. We look forward to traveling to Florida to see the satellite launch later this summer.”

Do we know which booster yet?B1047.2 ? same as Telstar 19V? 22 July 18 to 17/18 August, less than a month? Possible with block 5?B1046.2 ? Flew May 11 but was going for months of tests.B1048.2 ? flying from Vandenberg so more likely reuse also from Vandenberg with SAOCOM July 25th to Sept 5thB1050 ? B1049 flying 2 Aug, so doesn't seem like B1050 would be ready?
That's strange. It's out at the pad next to the TEL. Maybe they're taking it in through the door on the pad side for some reason?
B1049 arrives at SLC-40
About 3000 lbs less than T19V.I could have had exact but really my only concern is temps and pressure, I trust the propulsion team to know their target weights.

Prelaunch campaign @SpaceX #Telstar18v staticfiretest for launch NET Aug23 has begun!Evidenced by TE up at #pad40 noon today-minus booster. By 1245PM lowered,planes flew overhead/landed.I saw 1st stage arrive last week during #merahputih . @ken_kremer spaceupclose.com
Launch has slipped 2 days. New launch day and window:25 August at 23:33 EDT to 03:33 EDT on 26th.... which is 26 August from 0333-0733 UTC.
Payload Vehicle engineer for Telstar 18 on Reddit says there is a 5-10 day delay for the launch, may not be in August. Any confirmation for this?https://www.reddit.com/r/spacex/comments/95cte4/telstar_18v_apstar_5c_launch_campaign_thread/e4kgxuw/?context=3
Hate to tease you but right now there is no officially released reason so I can't say. Even being on the customer side they won't tell me too much.
A 24 day gap is no way to hit a 30 launch per year pace, especially when it's followed by a 30 day gap.
I don't think SpaceX can be criticized for being slow about launching rockets, since they launch more than anyone else in the world.
I have a theory.Telkom-4 (Merah Putih) was originally expected to launch on F9 core B1049. Unexpectedly after having loaded that core into the SLC-40 hangar in preparations for flight they pulled it out and took it back to the LC-39A hangar and the sooty and flight proven B1046 was moved into the SLC-40 hangar and ended up being the rocket that performed the mission.Now here we are and B1049 is scheduled to launch Telstar 18V and the mission was delayed from August 16th to 23rd to 25th and now into September.I'm wondering if there is something wrong with that booster that's taking longer than expected to fix?
That's a myth. China has launched 22 times this year compared to SpaceX with 15 launches.

Not sure if I'm reading this right. So launch has adjusted a few minutes, which now puts it just after midnight EDT on Sunday, 9 September? Or are we still at roughly 23:23 EDT on 8 September and this another one of the 45th's EDT/UTC mismatches?
I figure no news is no news...Is the static fire still on for tonight?
Why was this pushed back anyway?

The new launch date was announced as Sunday night. I think we can rule out hurricane as the explanation, since it will be closer to the landing site on Sunday than Saturday.

Quote from: Nehkara on 09/07/2018 09:47 pm[Image]Does anyone know the current location of OCISLY?Is it anywhere near this brand new yellow X on the map?We don't know where it is now, but the planned recovery location--based on the FCC filing for this mission--was approximately in the area I marked below (BTW, I borrowed the marker directly from the underlying image, so it's no longer indicating the post storm remnants). Whether that recovery zone is still the current one or if sea states or other long range storm effects have necessitated any changes we don't know. Also, please note (Nehkara, Alexphysics, and all others): NSF site preference/guidelines is that all images be attached instead of directly linking to them. It requires an extra step of first saving/downloading a copy of the original image so that you can then attach it as a file when you comment, but it is easily accomplished by just right-clicking on the original image and choosing "save image" or similar option. Attaching, instead of linking, prevents the images from interfering with NSF's ability to have the site layout automatically adjust to fit variously sized screens. This policy should not only be adhered to by those posting but also by those quoting comments that include a unknowingly linked image. If you're unsure how to do this, you can look at how either @gongora or I have quoted Nehkara's comment and then edited the actual image link out of it (I just deleted the line of text which had the url/hyperlink and then included a placeholder marker). Thank you.
For Sunday’s Falcon 9 launch, I’ll be accompanied by some folks from VICE! They’re making an HBO special about my coverage for this launch, looking at what goes into covering photographing rocket launches as a member of the media.

Was it just me or did the rocket seem to have more acceleration, especially coming off of the pad?
It looks to me that S1 is leaning to the right.Optical illusion or possible deformation of the legs?
MECO seems to happened lot sooner than timeline show, also meco to stage separation (mainly to the change view to inside of the intersatge) feels lot longer. Of course there can't be any actual problem coz S1 is on the droneship...
A first object has been cataloged:2018-069B/43612 in 259 x 18060 km x 26.95°
I liked how they used a graphic of Martian terraforming as a placeholder for their webcast long prior to the launch:They've probably been doing that for awhile, but this is the first SpaceX launch I've watched live in some time.
Which works out to GTO-2267. Very similar to Telstar 19V (243 x 17863 km x 27.00º orbit, GTO-2277).

Is it advantageous for satellite company to built heavy satellite with large amount of fuel to make ~2200 m/s maneuvr?Because Falcon 9 has a kerosene upper stage, it's performance changes pretty rapidly with the delta-v required. Customers really, really want to get the price from SpaceX they can get from letting SpaceX recover the core, so they need to let SpaceX have the margin for propellant to land on the barge. That means lower first-stage delta-v and higher second stage delta-v, which drops payload pretty quickly. For instance, while F9 with ASDS landing can deliver about 7 metric tons to this GTO-2270 orbit, it can only deliver about 4 metric tons to GTO-1800. That's the difference between the satellite making it to GTO with a beginning-of-life mass of 2.25 metric tons or 3.35 metric tons. Thus, by loading the satellite with more propellant and having it act more as its own "third stage," you can more efficiently split the delta-v and get almost 50% more mass to geostationary orbit--and more importantly launch a bus of a commercially standard size while still allowing the core to be recovered.Given how well this size fits on F9 with this mission mode, I'm not sure I'd see satellites of this size switching to Falcon Heavy. However, anything larger would need to, as there's not much further the technique can be pushed.
Block 5 can do much better than 4,000 kg to GEO-1800 with a landing. F9 Block 3 has delivered 5200 kg to a super synchronous GEO-1773 with ASDS landing, and Block 5 is substantially more powerful. It can do at least 5,500 kg to GEO-1800, and probably more, depending how hot they want to let the booster get on entry.https://forum.nasaspaceflight.com/index.php?topic=40725.msg1735694#msg1735694

I wonder if these big birds move over to the FH in a year or two.
Quote from: wannamoonbase on 09/10/2018 01:38 pmI wonder if these big birds move over to the FH in a year or two.Why would they do that?It seems obvious that Telstar decided to trade launcher performance for lower cost with these launches in electing to put up a heavy fuel mass in the sat to a subsynchronous GTO. Switching to FH would be going in the opposite direction.
I tried to look up the cost delta, thanks. Seeing the trade between hypergol, ion thrusters, cost and revenue would be interesting.
I don't know. The Everyday Astronaut mentioned in his coverage of the launch that having the sat be it's own third stage allowed it to be about 500kg heavier than if the Falcon 9 second stage did all the work. I don't know the source of those numbers.

Last view before landing. Landing confirmed!
Quote from: JimO on 09/10/2018 07:32 pmDid stage-2 do a small apogee slow-down burp to deorbit?They don't have the capacity right now to deorbit second stages on GTO missions and this should be on the discussion thread.
So overall, by using this strategy, the satellite manufacturer gets about 500 kg more to a GEO-apogee GTO than they would have gotten from the F9 directly.

(They may choose not to do this for many reasons)

This wouldn't be possible if it was a shadow cast on the grid fin.
