Alexander Gerst engagement report
@Astro_Alex - 1.1M followers on X
Measured over 2 original posts from a 30-day window, last computed on September 1, 2026.
Engagement
Early reading. We have captured 2 original posts for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 704 interactions against 1.1M followers, an engagement rate of 0.067%. Posts are seen about 30K times each, and 2.34% of those impressions turn into an interaction. That is about 2.87% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.07 posts a day over the last 30 days, though only 7% of days saw any activity at all. Most posts go out around 07:00 UTC, and Tuesday is the busiest day of the week. Of the 2 posts sampled, 100% carry an image or video and 50% link out. The account's strongest tracked post pulled 26K interactions, about 37x its own typical post. Only 2 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 07:00 UTC, and Tuesday 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.

Currently editing tonight's shot... and WOW. This is probably my new favorite ISS transit shot... beating out the one I captured with the silhouette over Tycho crater. Here's that photo for reference: https://t.co/dbqbUt44w4

Godspeed my friends. I don’t have words to describe this feeling. Say hi to the Moon, and see you in 10 days. https://t.co/e96klRTk3m

Ein riesen-Tröööööt zum 50. Geburtstag, lieber #Elefant!🐘🎉 Deine Abenteuerlust und dein großes Elefantenherz inspirieren uns alle. Als #Maustronaut hast du mit mir gemeinsam bereits die Internationale Weltraumstation erkundet – und wer weiß, vielleicht heben wir bald wieder ab. Dein Raumanzug wartet in jedem Fall auf dich! https://t.co/5tnTIU2C4I

„Wir begannen als Wanderer, und wir sind immer noch Wanderer.“ Heute beginnt die zweite Welle der Erforschung des Weltraums. Vier von uns brechen auf, um weiter zu reisen als je ein Mensch zuvor, um zu sehen, was noch kein Mensch je gesehen hat. Und mit der Kraft dieser Welle werden wir dauerhaft als Forschende auf dem Mond bleiben – so wie wir es in der Antarktis getan haben. Europa und Deutschland sind Teil dieses Abenteuers – das erfüllt mich mit Freude. Gute Reise, Reid, Christina, Victor und Jeremy! Ich kann es kaum erwarten, den Donner eures Aufbruchs zu spüren – und freue mich noch mehr auf eure Rückkehr in 10 Tagen, zu dieser wunderschönen blauen Murmel, mit einer Geschichte, die uns alle berühren wird. @NASAArtemis @esaspaceflight

Unbeschreibliches Gefühl, einen Helikopter mit den eigenen Händen auf der Zugspitze im Schnee zu landen. 🚁🏔️ Hätte ich nicht für möglich gehalten, dass ich sowas in nur drei Wochen Training lernen kann. Krasses Kompliment an die Instruktoren der Bundeswehr Heeresflieger! 👏🏼 Landemanöver in engen Schluchten, auf schmalen Felsplateaus und im tiefen Schnee helfen uns, die nötige Präzision fürs vertikale Landen zu trainieren – eine Fähigkeit, die für @AstroSamantha, @astro_matthias , @Thom_astro, @astro_luca und mich bei möglichen künftigen Missionen zum Mond entscheidend sein wird. Denn die Mondlandefähren, die derzeit entwickelt werden, sind ebenfalls dafür ausgelegt, vertikal zu starten und zu landen. 🌕

Rollout has begun at #NASAMichoud, and several members of our NASA workforce are watching the move on this beautiful morning. This core stage will serve as the backbone of the SLS rocket for the Artemis III mission. Learn more at: https://t.co/wsbiHtVo9i https://t.co/HD7vq2tJ7k

Wenn ihr schonmal eine Sandburg gebaut habt, kennt ihr das sicher: Überall Sand – in den Schuhen, in der Kleidung, auf der Haut. Nervig! Aber stellt euch mal vor, der Sand wäre noch viel feiner, schärfer und hartnäckiger – und ihr könntet ihn nicht einfach mit Wasser abspülen. Genau so ist es auf dem Mond! 🌕 Damit wir besser verstehen, wie man mit diesem Mondstaub umgehen kann, wurde in Köln die Mondforschungshalle LUNA gebaut. Dort wird der Mond nachgebaut – mit speziellem Sand aus einem Steinbruch ganz in der Nähe. Ich war für euch vor Ort und habe mir angeschaut, wie das alles funktioniert und was man dort für zukünftige Mondmissionen lernt. 👨🚀✨ Neugierig? Dann schaut mal rein! – am Montag, 21.04. um 9:25 Uhr bei der Sendung mit der Maus oder zum Nachschauen in der ARD-Mediathek https://t.co/A67IVJ2wTR @WDR

Die Maus als Entdeckerin hat mich mal wieder auf ein Abenteuer begleitet – diesmal fast bis zum Südpol auf der Suche nach Meteoriten. Extreme Kälte, Stürme, atemberaubende Landschaften und wichtige Forschungsarbeit für das Verständnis der Welt – und das Beste: Es hat sogar etwas mit dem Mond zu tun! Jetzt unser Antarktis-Abenteuer in der ARD-Mediathek miterleben: https://t.co/PwB3ePlehd
