Are you sure that Gsat-11 will fly on September 5th ? Where is the satellite at the moment ? Has it left India ?

We're sure that GSAT 11 won't be flying on 5 September. The co-passenger for VA243 is Horizons 3e. We don't know when GSAT 11 is launching.

Per the Arianespace Launch schedule by Salo, GSat 11 is scheduled for NET November 2018.

However, it could be delayed a bit further. If not, then the date will stay intact.

Horizons 3e was announced at about 6.5 tons. This means Azerspace-2 can not weigh more than 3.5 tons.
The mass of Azerspace-2 is unknown, but based on its data:
35 transponders with 150 watts, I had assumed that it is heavier.
Obviously not.

Intelsat promises the service of Horizons 3e for the end of 2018. So the launch has to take place soon.

Looks like Intelsat 38 may have just been delivered (there was an AN-124 flight from Mountain View to Cayenne).

Looks like Horizons 3e was just delivered to Cayenne, saw an article or tweet somewhere yesterday confirming Azerspace-2/Intelsat 38 was on the previous Antonov flight.

Horizons 3e is currently scheduled for launch on 7 September, 2018 during a window that is currently scheduled to open at 5:56 pm EDT and closes at 6:31 pm EDT. Following a successful launch, Horizons 3e will be placed at the 169° East orbital location, where it will undergo in-orbit testing prior to its expected in-service date in the first quarter of 2019.

Already the 8th of September in Japan

The team in Kourou continues to prepare Azerspace-2/Intelsat 38 for launch.
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

Keeping the launch pace with Flight VA243 in September

Arianespace’s Flight VA243 on September 7 will be a milestone in the career of Ariane 5, marking the 100th liftoff of the workhorse heavy-lift vehicle. For this evening launch, the Ariane 5 ECA version – equipped with the ESC-A cryogenic upper stage – will be used on another of Arianespace’s dual-payload missions to geostationary transfer orbit. The Ariane 5 is provided by ArianeGroup as production prime contractor.

Horizons 3e, to be installed as Ariane 5’s upper passenger on Flight VA243, is owned by a joint venture of Intelsat and SKY Perfect JSAT Corporation. In completing Intelsat’s EpicNG global coverage, it will provide coverage for aeronautical and maritime mobility, fixed and wireless operators, as well as mobility and government customers. Built by Boeing, this is the first Intelsat EpicNG satellite to feature entire Ku-band spot beams utilizing multiport amplifiers that optimize power across the satellite.

The Azerspace-2/Intelsat-38 payload to be orbited by Flight VA243 from Ariane 5’s lower passenger position is designed to provide a range of telecommunications relay duties at the service of its two operators.

For Azercosmos – a company owned by the government of Azerbaijan Republic – the satellite will support growing demand for Direct-to-Home (DTH), government, and network services in Europe, Central and South Asia, the Middle East and Sub-Saharan Africa. For the Luxembourg-headquartered Intelsat, the spacecraft is to deliver continuity of service from the 45 deg. East longitude orbital location, which provides DTH platforms for Central and Eastern Europe as well as the Asia-Pacific region, while also offering connectivity for corporate networks and government applications in Africa.

Azerspace-2/Intelsat-38 was built by Palo Alto, California-based SSL.

At the end of the ADM-Aeolus webcast the commentator said VA243 is launching on 10 September. Go to 1:48:30 in the video.

The Horizons 3e satellite is fueled for a history-making dual-passenger flight on Ariane 5

The Horizons 3e telecommunications satellite has been fueled at the Spaceport in French Guiana, readying it for the 100th launch of a heavy-lift Ariane 5 – which also will carry the Azerspace-2/Intelsat 38 relay platform on this milestone Arianespace flight planned for September 25. ...

How is this mission "history-making"? Will Horizons 3e & Azerspace 2/Intelsat 38 break the record for the heaviest launch to GTO using Ariane 5?

When is the NLT date for this launch campaign not to interfere with the VA245/B-C launch campaign?

still within its window.

BC is in final stacking phase (2/4 components/2.3 SC stacked now) before transfer to the BAF for integration with the launcher. There will likely now be a multi launcher transfer performed when AS-2 and IS-38 rolls out with all three launch tables switching places.

The mission completed its Qualification Acceptance Review in the last week, which confirms it is on track for its 19 October launch. The three-spacecraft mission is currently scheduled to launch on an Ariane 5 at 03:45 CEST (01:45 GMT) on 19 October, or 22:45 local time in Kourou on 18 October, with the launch window remaining open until 29 November.

There are only 2 launch tables.

VA243 launcher has been moved to BAF (no image proof yet but that was the plan looking at the fueling of the S/C)
VA245 launcher will be stacked in BIL soon (my guess is by end of the coming week)

between the 2 launches there is still margin as range reconfig time is around 2 weeks.

maybe

Quote
Stage 3: Measuring the dry mass of the spacecraft – This task is performed on a special measurement system (load ring) that must be accurately calibrated. This is an important parameter because when fueling, the total mass of the spacecraft with fuel cannot exceed the contractual mass, which for Intelsat 38 is 3,500 kilograms. Since the lifetime of the spacecraft is directly dependent on the amount of fuel available, it’s important to utilize the remaining mass to its maximum potential by filling up the propellant tanks as much as the system allows.

The exact launch-mass of Horizons-3e is not yet known.
At the conclusion of the contract, 6500 kg were announced.

About 10 t net payload mass.

VA-237 holds the record.

Quote
The Ariane 5 ECA also set a new performance record into geostationary transfer orbit, carrying a total payload of 10,865 kg. (of which 9,969 kg. was the net liftoff mass for the two satellites).

---

Anyway... If the dates for VA243 and VA245 does not change, this is the shortest distance between two Ariane 5 launches.
