NASA Science engagement report
@NASAScience_ - 1.3M followers on X
Measured over 15 original posts from a 30-day window, last computed on August 31, 2026.
Engagement
A typical post picks up 456 interactions against 1.3M followers, an engagement rate of 0.034%. Measured over 15 original posts, its engagement rate beats 54% of 3,758 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 31K times each, and 1.48% of those impressions turn into an interaction. That is about 2.32% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, with activity on roughly 63% of days. Most posts go out around 17:00 UTC, and Thursday is the busiest day of the week. Of the 15 posts sampled, 100% carry an image or video, 40% are part of a thread and 47% link out. The account's strongest tracked post pulled 1.2K interactions, about 2.7x its own typical post.

Compared with accounts its own size
NASA Science's engagement rate beats 54% of the tracked X accounts closest to it in follower count (3,758 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 62% 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 0.034%, NASA Science sits above the 25th percentile of the 36,378 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.08%.

Posting timing
This account posts most often around 17:00 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.

Every discovery begins with light. Explore @NASARoman before launch to see how it will capture light, turn it into data, and send its observations back to Earth from about a million miles away. Explore the spacecraft: https://t.co/dLekuwXszE https://t.co/4XVB2erxSA

Scientists may be able to spot new active regions on the Sun before they break through its surface. A NASA-led team just built an AI model that flags these brewing regions up to 12 hours before they break through the Sun's surface, by "listening" for tiny shifts in the star's sound waves: https://t.co/WtYQp5HK3Y 📸: Irina Kitiashvili/Spiridon Kasapis

How does our universe change over time? @NASARoman will provide a treasure trove of data to help us answer this question. Gravity should slow our universe’s expansion, but instead it’s speeding up. Dark energy appears to drive this acceleration, but we have a lot to learn. ⬇️ https://t.co/dukfW5gzDW

A typical 1980s video game screen had ~61,000 pixels. @NASARoman will capture 300 million. That’s nearly 5,000× more detail, giving scientists an unprecedented view of the universe. https://t.co/fmPUbPP6ab
Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.

Reading these numbers
A typical post picks up 456 interactions against 1.3M followers, an engagement rate of 0.034%. Measured over 15 original posts, its engagement rate beats 54% of 3,758 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 31K times each, and 1.48% of those impressions turn into an interaction. That is about 2.32% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, with activity on roughly 63% of days. Most posts go out around 17:00 UTC, and Thursday is the busiest day of the week. Of the 15 posts sampled, 100% carry an image or video, 40% are part of a thread and 47% link out. The account's strongest tracked post pulled 1.2K interactions, about 2.7x its own typical post.
- What is NASA Science's engagement rate on X?
- NASA Science (@NASAScience_) has an engagement rate of 0.034%, based on the median interactions across 15 original posts from the last 30 days against 1,328,414 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.034%, NASA Science sits above the 25th percentile of the 36,378 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 @NASAScience_ have real engagement?
- Its engagement rate beats 54% of the tracked X accounts closest to it in follower count (3,758 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 @NASAScience_ post?
- Most posts go out around 17:00 UTC, and Thursday is its busiest day, at roughly 1.9 posts per day across the measured window.
