International Space Station engagement report
@Space_Station - 8.9M followers on X
Measured over 56 original posts from a 30-day window, last computed on October 24, 2026.
Engagement
A typical post picks up 1.0K interactions against 8.9M followers, an engagement rate of 0.011%. Measured over 56 original posts, its engagement rate beats 36% of 20,444 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 80K times each, and 1.26% of those impressions turn into an interaction. That is about 0.9% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.1 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 18:00 UTC, and Thursday is the busiest day of the week. Of the 56 posts sampled, 80% carry an image or video and 93% link out. The account's strongest tracked post pulled 15K interactions, about 15x its own typical post. Recurring topics include #crew13, #hwhap, #icymi.

Compared with accounts its own size
International Space Station's engagement rate beats 36% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 10 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 54% 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 0.011%, International Space Station sits above the 10th percentile of the 204,491 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.024%.

Posting timing
This account posts most often around 18:00 UTC, and Thursday 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 | 80% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 93% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 80% 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.
- 93% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 222 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
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.

I‘ll stop posting timelapses of the aurora from the @Space_Station when I’m tired of looking at them . . . so basically never! Another unforgettable display of this ethereal phenomenon as it danced beneath us last night, this one even more special as it was shared with @astro_anil, as he witnessed it for the first time with such intensity. The red wavelengths (above the green) were particularly bright in this pass.

[🇫🇷 version FR 👇] Day 183 orbit 2837 — 🚨 Did you know I will be going out on my first EVA on Tuesday 18 August? @astro_anil and I will spacewalk together to replace a Space-to-Ground antenna which (as its name indicates) is a critical piece of hardware, allowing communications between the ground control teams in Houston and the International Space Station. Spacewalks don't start when the hatch opens. They begin long before that, with countless hours of preparation: readying the spacesuits, charging and replacing batteries, inspecting safety tethers, organizing the equipment we'll carry into space, servicing the SAFER jet packs, and much more. These photos were taken during suit fit checks. Since our first EVA training sessions in the NBL, each astronaut has worked closely with a dedicated suit engineer who helps customize every detail of the spacesuit 🧑🚀 until it feels right, from fingertips to toes. Whether it's relieving a pressure point or adjusting a component, they always seem to have a clever solution. And when you're preparing for one of the most challenging tasks astronauts perform, comfort inside the suit is not a luxury, it’s a necessity. The suit was powered on and pressurised – no leaks – and we successfully checked the biosensors, as well as the communication and life support systems! 👌 I’m ready to go! 📸 @esa / @NASA Jour 183, orbite 2837 – 🚨 Savez-vous que je vais effectuer ma première sortie extravéhiculaire le 18 août ? @astro_anil et moi sortirons dans le vide spatial pour remplacer une antenne SGANT – un équipement essentiel qui permet les échanges entre le Centre de contrôle à Houston et la Station spatiale internationale. Une sortie dans l’espace commence bien avant l’ouverture du sas, avec d’innombrables heures de travail en amont : préparation des scaphandres, recharge et remplacement des batteries, inspection des longes de sécurité, organisation du matériel que nous emporterons à l’extérieur, entretien du propulseur de secours (SAFER) et bien plus encore. Ces photos ont été prises lors d’essais du scaphandre. Depuis les premières séances d'entraînement dans le NBL, chaque astronaute travaille avec un ingénieur dédié qui aide à adapter minutieusement le scaphandre 🧑🚀 pour qu’il soit le plus confortable possible, du bout des doigts jusqu’aux orteils. Qu’il s’agisse de soulager un point de pression, d’ajuster un composant ou d’améliorer un détail, ils ont toujours une solution ingénieuse à proposer ! Et lorsqu’on se prépare à l’une des tâches les plus exigeantes du métier d’astronaute, le confort n’est pas un luxe, c’est une nécessité opérationnelle. Le scaphandre a été mis sous tension puis pressurisé, et aucune fuite n’a été détectée. Nous avons également vérifié avec succès les capteurs biomédicaux, ainsi que les systèmes de communication et de support de vie. 👌 Je suis prête ! #εpsilon • @Space_Station • @NASAJohnson • @CNES • @esaspaceflight • @ESA_fr

Day and night over Istanbul: Türkiye’s Bosphorus Strait splits the city, separates Europe and Asia, and links the Sea of Marmara with the Black Sea. By night, older amber lights contrast with newer, brighter LEDs. Istanbul Airport also stands out clearly in these views from the orbital outpost.

Reading these numbers
A typical post picks up 1.0K interactions against 8.9M followers, an engagement rate of 0.011%. Measured over 56 original posts, its engagement rate beats 36% of 20,444 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 80K times each, and 1.26% of those impressions turn into an interaction. That is about 0.9% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.1 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 18:00 UTC, and Thursday is the busiest day of the week. Of the 56 posts sampled, 80% carry an image or video and 93% link out. The account's strongest tracked post pulled 15K interactions, about 15x its own typical post. Recurring topics include #crew13, #hwhap, #icymi.
- What is International Space Station's engagement rate on X?
- International Space Station (@Space_Station) has an engagement rate of 0.011%, based on the median interactions across 56 original posts from the last 30 days against 8,884,643 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.011%, International Space Station sits above the 10th percentile of the 204,491 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 @Space_Station have real engagement?
- Its engagement rate beats 36% of the tracked X accounts closest to it in follower count (20,444 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 @Space_Station post?
- Most posts go out around 18:00 UTC, and Thursday is its busiest day, at roughly 3.07 posts per day across the measured window.
