At ongoing ESA Ariane 6 press bfg, ESA DG Aschbacher still won't say when the 1st launch might be, even whether it will be in first half of 2024.

Ariane 6 joint update report, 4 September 2023

04/09/2023

ESA / Enabling & Support / Space Transportation

The Ariane 6 Launcher Task Force consists of top management at ESA, the overall Ariane 6 procuring entity and launch system architect, launch base prime contractor and French space agency CNES, launcher system prime contractor ArianeGroup and launch service provider Arianespace. This group reports regularly on progress being made towards inaugural flight of the new Ariane 6 launcher.

The next update is expected in October.

Key milestones towards inaugural flight:

18 July 2023: Combined tests, hot firing test of the main stage with Vulcain 2.1 engine ignition - At Europe’s Spaceport in Kourou, French Guiana, engineers from ArianeGroup, CNES and ESA, successfully completed for the first time a launcher preparation and countdown sequence.

The 26-hour test included the removal of the mobile gantry, the chill-down of ground and launcher fluidic systems, the filling of the upper and core stage tanks with liquid hydrogen (–253°C) and liquid oxygen (–183°C), and the successful completion of a launch chronology up to the ignition of the Vulcain 2.1 engine thrust chamber by the ground system.

During the exercise fully representative of a launch chronology, the teams successfully tested many degraded and contingency modes, demonstrating that the launcher and the launch base fit correctly. Operational procedures, lower and upper stages, avionics, software, launch base and control bench worked correctly together, and the performance of the full launch system was measured with excellent results.

1 September 2023: Upper stage hot firing test, Lampoldshausen - At German aerospace agency DLR’s rocket engine test centre in Lampoldshausen, Germany, engineers from DLR, ArianeGroup and ESA completed another hot-fire test, representative of the inaugural flight.

Assembled at ArianeGroup’s site in Bremen, Germany, the Ariane 6 upper stage incorporates some of the launcher’s main innovations, enabling it to carry out the widest possible range of launch missions, including complex ones such as large-scale deployment of satellite constellations in low Earth orbit (LEO), or successive injection of payloads into different orbital planes. At the end of its mission, the stage is de-orbited.

The stage includes two main tanks for cryogenic propellants (liquid hydrogen and oxygen) to power the Vinci engine which can be re-ignited up to four times, and the innovative Auxiliary Power Unit (APU).

The upper stage test sequence was representative of its full operating phase during Ariane 6’s inaugural flight.

It involved more than 11 minutes (680 seconds) of operation of the Vinci re-ignitable engine in two boosts in parallel with operation of the APU (Auxiliary Power Unit) which was in operation for a cumulative period of nearly 30 minutes.

The APU makes it possible for Vinci to restart in space, by maintaining adequate pressure in the fuel tanks and preventing bubbles in the fuel lines. The APU uses small amounts of liquid hydrogen and oxygen from the main tanks – replacing a system which relied on large quantities of tanked helium. 

Next milestones:

5 September 2023: Combined tests, hot firing test of the main stage with Vulcain 2.1 engine stabilized operation, Kourou – This second hot-fire test of the main stage will be very close to the previous one (18 July), but will end with 4 seconds of stabilized operation of the Vulcain 2.1 engine.

This test is a key milestone in the combined tests campaign. Its success will enable qualification of all the operations of an Ariane 6 launch countdown. It is part of the overall qualification of the launch system, comprising the launcher and its ground installations, notably the ELA4 launch complex dedicated to Ariane 6, and its ZL4 launch zone.

3 October 2023: Combined tests, long-duration hot firing test of the main stage with Vulcain 2.1 engine stabilized operation, Kourou – This long-duration test will end with about 8 minutes (470 seconds) of stabilized operation of the Vulcain 2.1 engine.

This test will cover the entire flight phase of the core stage and will contribute to “flight-ready” qualification of the main stage.

End-2023: Upper stage hot firing test, Lampoldshausen – Further hot-firing test of the upper stage planned to examine stage behaviour in degraded cases. The objective is to deliver a more robust Ariane 6.

Ariane 6 is an all-new design, created to succeed Ariane 5 as Europe's heavy-lift launch system. With Ariane 6's upper stage restart capability, Europe's launch capability will be tailored to the needs of multiple payload missions, for example to orbit satellite constellations. This autonomous capability to reach Earth orbit and deep space supports Europe's navigation, Earth observation, scientific and security programmes. Ongoing development of Europe's space transportation capabilities is made possible by the sustained dedication of thousands of talented people working in ESA's 22 Member States.

Ariane 6 media briefing – September 2023

If data consumption and bandwidth are not an issue, it is best to watch the source video. Download: SOURCE mp4
The compressed mp4 has a poor quality and a audio offset.
Unfortunately, the pointless blue "picture frame" remains.

I looked into this, and sure enough, the mobile gantry had rolled back leaving the rocket exposed and venting was visible near the pad!

News release: Fuelled-up dress rehearsal for Ariane 6

06.09.2023

At Europe’s Spaceport in French Guiana, ESA’s new Ariane 6 launch vehicle, consisting of its upper and core stage has been fuelled up and its core stage engine fired. With the rocket standing on its launch pad, the Vulcain 2.1 engine was ignited, fired for four seconds as planned and switched off before its liquid oxygen and liquid hydrogen fuels were drained to their separate underground tanks. These tests are the continuation of an earlier test on 18 July.



The exercise, conducted by CNES and ArianeGroup under the lead of ESA, checked pre-launch procedures and ignition, and showed again, that the system can be kept safe in the event of a launch abort, as already demonstrated during the 18 July test. Fuelling and ignition was the latest in an ongoing series of tests to validate that the rocket, launch pad, protective gantry and all related fluid and electrical connections work properly as a combined system.



The Ariane 6 rocket now installed on the launch pad is not intended for flight – the solid rocket boosters are inert – but it is almost identical to a flight model for purposes of testing. Flight models, including the rocket that will make Ariane 6’s inaugural flight, are being manufactured and assembled under the responsibility of ArianeGroup, the prime contractor in Les Mureaux, France and Bremen, Germany. The solid rocket boosters for the first flight are being aseembled in Kourou, French Guiana.



Coming soon will be a longer-duration firing of the Vulcain 2.1 engine, of about 470 seconds to simulate an actual flight. This test will also be done on the launch pad.

ESA Director of Space Transportation Toni Tolker-Nielsen remarked: "We have a fantastic team working on this programme. We can all feel it - we are taking the final steps towards entering into the Ariane 6 era.”



Ariane 6 is an all-new design, created to succeed Ariane 5 as Europe's heavy-lift launch system. With Ariane 6's upper stage and its reignitable Vinci engine, Europe's launch capability will be tailored to the needs of multiple payloads, for example to orbit satellite constellations. This autonomous capability to reach Earth orbit and deep space supports Europe's navigation, Earth observation, scientific and security programmes. Ongoing development of Europe's space transportation capabilities is made possible by the sustained dedication of thousands of talented people working in ESA's 22 Member States.

Ariane 6 task force update: great data and results from the hot-fire September tests for #Ariane6 both in French Guiana and Germany. However, an anomaly was detected in the thrust control vector hydraulics when preparing for the next test and the long-duration hot firing test will no longer take place on 3 October as teams investigate the causes. We will come back to you with more updates when available.

🚨Ariane 6 update🚨
In order to optimise the #Ariane6 testing schedule, the test sequence has been inverted. This allows us to anticipate the launch rehearsal test, followed by the long-duration firing test of the main stage Vulcain 2.1 engine, and ultimately reduces any impact on the overall schedule.

*Next milestones*
October: Combined test, launch rehearsal with ignition of the main stage, Kourou, French Guiana

November: Combined test, long-duration firing of the main stage with Vulcain 2.1 engine, Kourou, French Guiana

December: Upper stage firing test, Lampoldshausen, Germany

Ariane 6 joint update report, 19 October 2023

19/10/2023

The Ariane 6 Launcher Task Force consists of top management of ESA, as the overall Ariane 6 procuring entity and launch system architect, of the French space agency CNES, as the launch base prime contractor, of ArianeGroup as the launcher system prime contractor and of Arianespace as the launch service provider. This group reports regularly on progress being made towards inaugural flight of the new Ariane 6 launcher.

Key milestones towards inaugural flight:

On the way towards the inaugural flight of Ariane 6 two important tests have already been implemented. On 18 July the hot firing test of the main stage with the Vulcain 2.1 engine ignition in Kourou was successful, completing for the first time the launcher preparation and countdown sequence. On 1 September the upper stage hot firing test in Lampoldshausen was also a success, representing the full operational phase during Ariane 6’s first flight.

During the preparatory operations for the next test, the long-duration firing test, initially planned on 3 October in Kourou, an anomaly has been detected on the core stage’s hydraulic group. This equipment made by SABCA (Belgium) is part of the Thrust Vector Control (TVC) system of the core stage. The role of the TVC system is to maintain the launcher's correct attitude by gimballing the Vulcain 2.1 engine during its operation. Activation of the TVC is part of the long duration firing test.

A group of experts has been tasked to analyse and propose solutions to resolve the anomaly, characterised by an abnormal internal pressure of the hydraulic group. Because of the time needed by the experts to disassemble the equipment, assess the problem and determine the root cause, the schedule for Ariane 6 launch rehearsals has been adapted. In order to optimise the schedule the test sequence has been inverted leading to the anticipation of the launch rehearsal test under different environmental conditions followed by the long-duration firing test of the main stage Vulcain 2.1 engine.

The modification of the test sequence allows the Ariane 6 teams to keep the pace on the progressive achievement of qualification objectives and to reduce any impact on the schedule.

Next milestones:

October 2023: Combined test, launch rehearsal with ignition of the main stage, Kourou, French Guiana

As part of the test sequence reconfiguration, the Ariane 6 Task force decided to bring forward to end of october a rehearsal test originally planned to be held after the long firing test.

This full-scale 36-hour long test is compatible with the parallel resolution of the anomaly on the hydraulic group. It consists in the execution of a full launch chronology enriched by qualification tests on several launch system functions including ventilation of cavities, launch range interfaces, and environmental characterisation. This time, operations will be executed during the coolest hours of the day at dawn time. 

The test results will be part of the Ariane 6 qualification.

November 2023: Combined test, long-duration firing of the main stage with Vulcain 2.1 engine, Kourou, French Guiana. 

Similar to the previous hot-firing rehearsals, this test will end with a full eight minutes (470 seconds) of firing of the Vulcain 2.1 engine, representing the entire flight phase of the core stage.

The anomaly affecting the hydraulic group of the TVC system resulted in a change of the test schedule. ArianeGroup as prime contractor and SABCA as supplier already prepared a replacement specimen of the hydraulic group, without waiting for the results of the technical investigation. Once the equipment is integrated on the Ariane 6 launcher specimen, teams will finish preparations for the test which is now planned on 23 November.

As per standing plan, the Ariane 6 first flight launch period estimate will only be given when the combined long firing test will have been carried out and the test results are analysed.

December 2023: Upper stage firing test, Lampoldshausen, Germany

It is planned to examine stage behaviour in degraded cases.

The adaptation of the test sequence keeps the Ariane 6 development on track for a launch in 2024.
