Looks like our #Galileo launch next year will be the last launch of the  #Ariane5 ES model ever..... #ATV #VA233 #VA240

More #Galileo launcher info, heard that the spare Aestus EPS engine (sn55) for next years A5 launch was tested successfully in July @DLR_en

Ariane 5 ES was mainly there to launch ATV's. Now that those are no longer flying there is also no longer any need for the EPS upper stage.

Well, what if there was a failure in the ESC-A upper stage? Then they would resort to the EPS upper stage during that investigation.

Well after 62 missions of the ESC-A upper stage and 195 flights total of the HM7B engine it's pretty safe to rule out any non-discovered design issues.

And since there is no EPS in storage the lead time to build a new one (if  possible) would be prohibitive as well.

Advance apologies if this is a re-stating of the obvious to the reader...I looked to see if there were any more payloads like Envisat (massive satellites bound for LEO) in the Ariane manifest which might be better served by an EPS upper stage vs. ESC-A...there are no more such payloads.

No there are 0 large LEO/SSO payloads on ESA/European institutions launch manifest that can not be launched by a Soyuz. Ariane 5 ES (galileo) was cheaper when it orbits four Galileo satellites, than two Soyuz launches with two Galileo satellites.
After this (last) Ariane 5 ES 4x Galileo launch. The next launch is 2x A62 with both two galileo satellites.
I predict t this will be the second and fifth Ariane 6 launches.
There are Ariane 5 launcher serial numbers reserved for aditional Ariane 5 ES flights. But those will most likely not be used.

AFAIK there is a agreement between Arianespace (ESA) and IHI (JAXA) that Ariane 5 and H2 serve as backup for each other,  in case of a anomaly. So I don't think A5ES will launch in the unlikely event of a A5 ECA failure.

I've to add this tweet from DutchSpace:
Apperently ESA has a option for a aditional Soyuz (2× Galileo) launch.
But most likely it will not be taken (only if more clocks fail, and Sats loose functionality, I guess).

sure, VA244 on the 25th of July if all goes to plan it will be the 100th Ariane 5 launch

Nope, with the VA243 rescheduled, VA244 will be the 99th Ariane 5 launch, but the 100th Ariane 5 built

SATELLITE PAIR ARRIVE FOR GALILEO’S NEXT RUMBLE IN THE JUNGLE

9 May 2018

The next two satellites in Europe’s Galileo satellite navigation system have arrived at Europe’s Spaceport in Kourou, French Guiana, ahead of their planned launch from the jungle space base in July.

Galileo satellites 23 and 24 left Luxembourg Airport on a Boeing 747 cargo jet on the morning of 4 May, arriving at Cayenne – Félix Eboué Airport in French Guiana that evening.

They were then unloaded, still in their protective air-conditioned containers, and transported by truck to the cleanroom environment of the preparation building within Europe’s Spaceport.

This pair will be launched along with another two Galileo satellites, which are due to be transported to French Guiana later this month.

The quartet will be launched together on a customised Ariane 5 on 25 July.

The Galileo System began Initial Services on 15 December 2016, and a growing number of commercial devices are using Galileo today. Completion of the constellation should improve Galileo’s positioning accuracy further still.

But Galileo satellites will continue to be launched into the future: a further 12 Galileo ‘Batch 3’ satellites were ordered last June, supplementing the 26 built so far to provide further in-orbit spares, and replacements for the oldest Galileo satellites, first launched in 2011.

A steady stream of orbital spares, ready to replace satellites reaching the end of their operational lives, is essential to ensure Galileo continues operating seamlessly.

Looking further ahead, with the aim of keeping Galileo services as a permanent part of the European and global landscape, replacement satellites will be required by the middle of the next decade, offering improved performance and added features.

About Galileo

Galileo is Europe’s own global satellite navigation system, consisting of both the satellites in space and their associated ground infrastructure.

The definition, development and in-orbit validation phases were carried out by ESA, and co-funded by ESA and the European Commission. This phase created a mini-constellation of four satellites and a reduced ground segment o validate the overall concept, ahead of further deployment.

Success led to the current Full Operational Capability phase, fully funded by the EU and managed by the Commission. The Commission and ESA have a delegation agreement by which ESA acts as system design authority and procurement agent on behalf of the Commission.
