Lengthy delays for the debut of Europe\u2019s future flagship rocket may have an end in sight. During a briefing with press on Thursday, European Space Agency Director General Josef Aschbacher announced that Ariane 6 would have its first launch between mid-June and the end of July in 2024.<\/p>\n

The announcement comes a week after a seven-minute hot fire test of the rocket\u2019s core stage engines in Kourou, French Guiana. The hefty delays to a launch vehicle that was originally supposed to debut in 2020 stem from a combination of \u201cvery severe\u201d technical issues and a mismanaged schedule, according to Aschbacher.<\/p>\n

\u201cWhen I started as DG of ESA some two and a half years ago, I asked immediately for an assessment of the situation on Ariane 6 and it became crystal clear after a few months of very intense investigations that the schedule and some technical issues on Ariane 6 are not in a very good shape,\u201d he said. \u201cThis is something that of course is highly disturbing.\u201d<\/p>\n

The intention was for the Ariane 6 to start flying while overlapping the Ariane 5, so that there would be a smooth transition of launch capabilities, similar to what United Launch Alliance is doing with its shift away from its Atlas 5 and Delta 4 Heavy rockets and towards Vulcan.<\/p>\n

ESA was hit with a double whammy when its small launch vehicle, Vega C, was grounded late last year following an anomaly about 150 seconds into flight.<\/p>\n

Aschbacher said there were two main lifelines that are helping them navigate this European launch \u201ccrisis\u201d: working to aggressively book flights on the Ariane 6 and the Vega C through the end of the decade and kicking off a launcher challenge to spur the creation of more commercial rockets.<\/p>\n

\u201cThis looks beyond Ariane 6 and beyond Vega C to create a new launcher of the future, which of course will only fly in the next decade,\u201d Aschbacher said.<\/p>\n

He pointed to the Ariane 6 Launcher Task Force, which has also helped in steering the ship towards getting the rocket on track towards a summer 2024 launch.<\/p>\n

One of the biggest milestones before the Ariane 6 maiden launch was the hot fire test, which happened on Nov. 23 and was designed to cover \u201cthe entire core stage flight phase,\u201d according to the latest task force summary.<\/p>\n

While the burn of the Vulcain 2.1 engine didn\u2019t last the full, advertised 470 seconds, Toni Tolker-Nielsen, the director of space transportation at ESA, said that they were still able to achieve all of their test objectives.<\/p>\n

With that in the rearview mirror, there are two more key milestones on the agenda for the remainder of 2023. The first is targeting Dec. 7 and will be a hot fire test of the Ariane 6\u2019s upper stage engine and the second is the combined test loading (CTLO3) on Dec. 15. That second test, essentially a wet dress rehearsal, will conclude with a short engine burn.<\/p>\n

Assuming both are successful, the ship carrying the components of the Ariane 6 will depart Europe near the end of January or the beginning of February, arriving in French Guiana near the end of February. Following assembly, the rocket would arrive at the launch pad by the end of April.<\/p>\n

Martin Sion, the CEO of AiraneGroup, said if that all goes well, the test campaign would take place in May and the start of June, leading to the earliest possible launch date of June 15.<\/p>\n

Aschbacher said that date is their ideal target, but they built in \u201crisk margin\u201d through the end of July on the off-chance that not everything goes to plan. He said they expect to be able to narrow down the date around the March or April timeframe.<\/p>\n

\u201cThis is a very complex undertaking to bring a launcher to the launchpad. Literally, it is rocket science that is here at stake and therefore, it is to be expected that there may be one or another delay that can occur,\u201d Aschbacher said. \u201cWe will continue our task force meetings towards the maiden flight and as soon as we can narrow that down as we progress\u2026 we will be in a good position to fix a date or maybe its a date plus or minus a few days of margin.\u201d<\/p>\n

The first mission\u2019s payloads were announced more than a year ago, but the list was updated to include a CubeSat from NASA\u2019s CubeSat Launch Initiative (CSLI). The ELaNa 48 (Education Launch of Nanosatellites) mission includes the CURIE (3U) CubeSat.<\/p>\n

The CubeSat Radio Interferometry Experiment from University of California at Berkely will be among those hitching a ride on this first flight.<\/p>\n

Future outlook<\/b><\/p>\n

Assuming everything can stay completely or mostly on track and a successful summer launch is completed, St\u00e9phane Isra\u00ebl, the CEO of Arianespace, said they are targeting a commercial launch by the end of 2024.<\/p>\n

\u201cWe will do as many flights as possible in 2025 and we will benefit from the return on experience of the two flights of 2024,\u201d Isra\u00ebl said. \u201cAnd you know that on a steady basis, Ariane 6 would go to nine to ten flights per year.\u201d<\/p>\n

Several customers are eager to see the Ariane 6 start flying at a regular clip. Amazon is among those relying on the rocket to start getting a reliable cadence going, since it purchased 18 launches to deploy its Project Kuiper broadband internet satellites.<\/p>\n

\u201cFor years and years, Arianespace has been dedicated on the commercial to the GTO (geostationary orbit) market\u2026 and now more and more, we will work for low Earth orbit constellations,\u201d Isra\u00ebl said. \u201cAnd the good here, and I really want to insist on that, is the fact that Ariane 6 is perfectly adapted to this shift in the market.\u201d<\/p>\n
