NASA's Glenn Research Center engagement report
@NASAglenn - 326K followers on X
Measured over 8 original posts from a 30-day window, last computed on October 12, 2026.
Engagement
A typical post picks up 105 interactions against 326K followers, an engagement rate of 0.032%. Measured over 8 original posts, its engagement rate beats 39% 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 4.4K times each, and 2.40% of those impressions turn into an interaction. That is about 1.34% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.3 post a day over the last 30 days, with activity on roughly 50% of days. Most posts go out around 18:00 UTC, and Wednesday is the busiest day of the week. Of the 8 posts sampled, 100% carry an image or video and 50% link out. The account's strongest tracked post pulled 1.2K interactions, about 12x its own typical post. Recurring topics include #dawgpound, #hwhap, #spaceapps.

Compared with accounts its own size
NASA's Glenn Research Center's engagement rate beats 39% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 9 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 68% 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 0.032%, NASA's Glenn Research Center sits above the 25th percentile of the 205,152 accounts in this comparison. That places it in the below the median band, which runs 0.024% to 0.143%.

Posting timing
This account posts most often around 18:00 UTC, and Wednesday 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 | 50% 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.
- 50% 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 502 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.

It was great spending time with the team at @NASAglenn. One of the best parts of this job is hearing directly from the people making our missions possible. The engineers, scientists, technicians, and support teams at Glenn are contributing to the Moon Base architecture, the future of aeronautics, and getting NASA underway on nuclear power in space.

Today marks the late astronaut Neil Armstrong’s 96th birthday (the namesake of NASA Glenn’s Neil Armstrong Test Facility in Sandusky, Ohio)! 🎂 He was the first person to step foot on the Moon’s surface, saying the famous quote, “That’s one small step for [a] man, one giant leap for mankind.” As NASA looks ahead to Artemis III and beyond, we remember Neil Armstrong as a trailblazer of space exploration. Fun fact: Armstrong was born on Aug. 5, 1930, in Wapakoneta, Ohio. He began his professional career at the Lewis Flight Propulsion Lab (now NASA Glenn) as a research pilot.

Kryptonite may weaken Superman, but real‑life krypton fuel is giving our electric propulsion thrusters a “super” boost! NASA Glenn engineers tested two 12‑kilowatt HERMeS Hall thrusters running side by side — the same type set to take the Space Reactor‑1 Freedom spacecraft to Mars. Instead of traditional xenon, the thrusters ran on krypton, which is more cost-effective for long-duration journeys but can be tougher on hardware. Researchers studied their performance and how quickly their parts wore down. They found that Glenn’s magnetic shielding technology reduced wear-and-tear significantly, giving krypton-fueled thrusters the lifetime needed for round-trip Mars missions. As the thrusters were moved closer together, they continued to operate smoothly — a major step forward for future NASA electric propulsion spacecraft. More: https://t.co/6gI89726dN

Back and better than ever! 📡 After Typhoon Mawar caused severe damage to @NASA's Guam Remote Station in 2023, its central antenna is now fully rebuilt and back online. With restoration efforts led out of NASA Glenn, our experts played a key role in bringing the site back to full operations, ensuring critical missions operating near-Earth, like the @Space_Station and @NASAHubble, can continue transmitting important science and exploration data.

Reading these numbers
A typical post picks up 105 interactions against 326K followers, an engagement rate of 0.032%. Measured over 8 original posts, its engagement rate beats 39% 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 4.4K times each, and 2.40% of those impressions turn into an interaction. That is about 1.34% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.3 post a day over the last 30 days, with activity on roughly 50% of days. Most posts go out around 18:00 UTC, and Wednesday is the busiest day of the week. Of the 8 posts sampled, 100% carry an image or video and 50% link out. The account's strongest tracked post pulled 1.2K interactions, about 12x its own typical post. Recurring topics include #dawgpound, #hwhap, #spaceapps.
- What is NASA's Glenn Research Center's engagement rate on X?
- NASA's Glenn Research Center (@NASAglenn) has an engagement rate of 0.032%, based on the median interactions across 8 original posts from the last 30 days against 326,392 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.032%, NASA's Glenn Research Center sits above the 25th percentile of the 205,152 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 @NASAglenn have real engagement?
- Its engagement rate beats 39% 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 @NASAglenn post?
- Most posts go out around 18:00 UTC, and Wednesday is its busiest day, at roughly 1.3 posts per day across the measured window.
