International Space Station engagement report
@Space_Station - 8.9M followers on X
Measured over 52 original posts from a 30-day window, last computed on September 1, 2026.
Engagement
A typical post picks up 1.1K interactions against 8.9M followers, an engagement rate of 0.012%. Measured over 52 original posts, its engagement rate beats 49% of 3,881 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 124K times each, and 0.887% of those impressions turn into an interaction. That is about 1.39% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.4 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 19:00 UTC, and Friday is the busiest day of the week. Of the 52 posts sampled, 85% carry an image or video and 75% link out. The account's strongest tracked post pulled 15K interactions, about 13x its own typical post.

Compared with accounts its own size
International Space Station's engagement rate beats 49% of the tracked X accounts closest to it in follower count (3,881 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 53% 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 0.012%, International Space Station sits above the 25th percentile of the 37,701 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.081%.

Posting timing
This account posts most often around 19:00 UTC, and Friday 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.

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

I was worried I might get used to seeing sights like this. I don’t. This was a moon rise, on an iPhone, during a break from a required workout which is nearby the window. It reminds me to carry that same sense of awe when I return. Also, I can’t wait until we land on the moon again.

A bittersweet day on the @Space_Station, as we prepare to say goodbye to the Soyuz 74S crew. Expedition 74 has been full of science, technology demonstrations and station maintenance, and most importantly, enduring friendship and “huggles”. See you back on Earth my friends! https://t.co/B84kuzNq16

- What is International Space Station's engagement rate on X?
- International Space Station (@Space_Station) has an engagement rate of 0.012%, based on the median interactions across 52 original posts from the last 30 days against 8,897,178 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.012%, International Space Station sits above the 25th percentile of the 37,701 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 49% of the tracked X accounts closest to it in follower count (3,881 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 19:00 UTC, and Friday is its busiest day, at roughly 2.4 posts per day across the measured window.
