Measured over 13 original posts from a 30-day window, last computed on September 5, 2026.
Engagement
A typical post picks up 114 interactions against 303K followers, an engagement rate of 0.038%. Measured over 13 original posts, its engagement rate beats 44% of 6,874 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 6.3K times each, and 1.80% of those impressions turn into an interaction. That is about 2.09% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.77 post a day over the last 30 days, with activity on roughly 50% of days. Most posts go out around 17:00 UTC, and Monday is the busiest day of the week. Of the 13 posts sampled, 100% carry an image or video and 8% are part of a thread. The account's strongest tracked post pulled 1.3K interactions, about 12x its own typical post. Recurring topics include #rocketmakers, #civil, #ariane6.

Compared with accounts its own size
ArianeGroup's engagement rate beats 44% of the tracked X accounts closest to it in follower count (6,874 accounts, accounts of similar size (decile 7 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 63% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.
Where this sits in the catalog
At 0.038%, ArianeGroup sits above the 25th percentile of the 66,128 accounts in this comparison. That places it in the below the median band, which runs 0.016% to 0.1%.

Posting timing
This account posts most often around 17:00 UTC, and Monday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 100% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 0% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 100% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 0% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 336 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

🚀 A major milestone for Themis at Esrange Space Center. On 23 July 2026, ArianeGroup and SSC Space teams completed a flight chronology rehearsal, also known as a wet dress rehearsal, with the Themis reusable stage demonstrator, as part of the EU-funded SALTO test campaign. Using liquid nitrogen in place of liquid oxygen and liquid methane, the teams simulated launch operations under cryogenic conditions, with temperatures as low as -200°C. The full-day rehearsal covered the countdown chronology, from the pre-flight preparation of the demonstrator and launch pad to the post-virtual-launch operations required to safe the site. This test has provided essential data for the next stages of the campaign and marks further progress towards the Hop Test: Europe’s first flight test with recovery. Following SALTO’s test-and-learn approach, each successive demonstration helps develop and mature the technologies required for reusability, bringing Europe closer to sovereign capabilities in reusable space technologies. The teams are now working to define the window for the next test. #RocketMakers #Civil #Themis @SSCspace @EU_Commission @ESA_transport @projectsalto

ExoMars: heat shield enters integration phase The European ExoMars Rosalind Franklin Mission has reached another major milestone at ArianeGroup’s Issac site with the arrival of the Martian capsule’s Front Shield structure. Following a successful vibration test campaign designed to validate its mechanical resistance to the stresses of launch and the journey to Mars, the Front Shield has now entered the integration clean room. Teams have begun installing the Norcoat® Liège HPK space-grade cork thermal protection system, a material qualified by ArianeGroup to withstand the extreme conditions of Martian atmospheric entry. A key element of the mission, this heat shield will protect the Rosalind Franklin rover during its entry into the Martian atmosphere, when the capsule will reach speeds of nearly 21,000 km/h and temperatures of up to 1,800°C. With this new industrial phase, ArianeGroup teams continue to contribute to one of Europe’s most ambitious Mars exploration missions. ExoMars overall Program is led by @Thales_Alenia_S Italia (TAS-I) for the @esa. The Rosalind Franklin rover, developed by @Thales_Alenia_S Italy and Airbus Defence and Space UK, will search for signs of past or present life on Mars, notably using a drill capable of extracting samples from up to two metres below the surface. #RocketMakers #SpaceIndustry #Civil #Innovation

One mission. Different answers. Long-range ballistic systems are game changers on the battlefield: Range, payload, accuracy and mission profile can be tailored to meet a wide range of operational needs. That is why a ballistic line-up is not built around a single system, but around complementary solutions designed to address different mission profiles. Only a few actors are mastering the related technologies. ArianeGroup B-STRIKE line-up is not a single solution: based on a shared foundation, it offers a set of sovereign capabilities adapted to different mission profiles. Because meeting operational needs starts with having the right system. #RocketMakers #Defence #BStrikeLineUp

What makes a ballistic system… ballistic? A ballistic system leaves the atmosphere within moments, accelerates to extremely high speeds, and re-enters into the atmosphere, undergoes high thermal and mechanical stress and reaches precisely its objective on a previously calculated trajectory. This flight profile combines speed, altitude and precision to deliver long-range capabilities while following a trajectory calculated in a few minutes before launch. Behind this seemingly simple principle lies decades of expertise in propulsion, re-entry technologies, guidance, navigation and flight control. At ArianeGroup, this expertise forms the foundation of the B-Strike ballistic line-up, building on decades of experience acquired through France's strategic deterrence programmes since the 1990s. #RocketMakers #Defence #BStrikeLineUp

Behind every ballistic system stands an industrial ecosystem. Designing a sovereign ballistic capability goes far beyond developing a single product. It brings together engineers, industrial teams and decades of expertise across propulsion, guidance, navigation, flight control and system integration. Every discipline contributes to the final performance. Every team plays a part. Because sovereign capabilities are never built by a single technology. They are built by people. #RocketMakers #Defence #BStrikeLineUp

🚀 A launcher's fairing has one mission: protecting the payload. Achieving that mission is far more complex than it looks. https://t.co/itpgnok6n4

🚀 We all know Ariane 6's propulsion. Solid boosters.
Vulcain 2.1.
Vinci. But once MTG-I2 separates from the launcher, another ArianeGroup propulsion system takes over. Because launch is only the beginning of the journey. #RocketMakers #SpacePropulsion #MTGI2 https://t.co/KHfMbOKv4A

🚀 Why add two more boosters? Because some missions need more than a launcher. They need more power. 🧵 https://t.co/DclmOkVo3O

Reading these numbers
A typical post picks up 114 interactions against 303K followers, an engagement rate of 0.038%. Measured over 13 original posts, its engagement rate beats 44% of 6,874 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 6.3K times each, and 1.80% of those impressions turn into an interaction. That is about 2.09% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.77 post a day over the last 30 days, with activity on roughly 50% of days. Most posts go out around 17:00 UTC, and Monday is the busiest day of the week. Of the 13 posts sampled, 100% carry an image or video and 8% are part of a thread. The account's strongest tracked post pulled 1.3K interactions, about 12x its own typical post. Recurring topics include #rocketmakers, #civil, #ariane6.
- What is ArianeGroup's engagement rate on X?
- ArianeGroup (@ArianeGroup) has an engagement rate of 0.038%, based on the median interactions across 13 original posts from the last 30 days against 302,529 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.038%, ArianeGroup sits above the 25th percentile of the 66,128 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @ArianeGroup have real engagement?
- Its engagement rate beats 44% of the tracked X accounts closest to it in follower count (6,874 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @ArianeGroup post?
- Most posts go out around 17:00 UTC, and Monday is its busiest day, at roughly 0.77 posts per day across the measured window.
