A typical post picks up 342 interactions against 933K followers, an engagement rate of 0.037%. Measured over 20 original posts, its engagement rate beats 55% of 3,774 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 19K times each, and 1.80% of those impressions turn into an interaction. That is about 2.04% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.2 posts a day over the last 30 days, with activity on roughly 67% of days. Most posts go out around 15:00 UTC, and Wednesday is the busiest day of the week. Of the 20 posts sampled, 100% carry an image or video, 40% are part of a thread and 55% link out. The account's strongest tracked post pulled 77K interactions, about 226x its own typical post.

Compared with accounts its own size

NASA Goddard's engagement rate beats 55% of the tracked X accounts closest to it in follower count (3,774 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 67% 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 0.037%, NASA Goddard sits above the 25th percentile of the 36,521 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.08%.

Engagement rate as a share of followers, across the 36,521 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 107,166 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 15:00 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.

Engagement by hour posted, UTCTwenty-four bars, one per UTC hour. Each bar shows how posts published in that hour compare with their own authors' median engagement. Bars above the centre line ran higher than the median, bars below ran lower. A marker flags Busiest hour: 15:00 UTC.

    NASA and Katalyst Space have determined that Katalyst’s LINK spacecraft will not capture or boost our Swift observatory to a higher altitude to extend its science mission, due to an ongoing attitude control issue with the spacecraft. However, LINK will still attempt to conduct rendezvous and proximity operations with Swift, to demonstrate key capabilities for the future of space exploration. More: https://t.co/RV9QOBoRVL

    LINK, the robotic spacecraft from Katalyst Space designed to boost our Swift mission’s orbit, experienced issues with attitude control over the weekend, causing the spacecraft to spin and resulting in sporadic communications. The team is working to stop LINK’s spin over the next few days and then will update LINK’s guidance, navigation, and control to accommodate the spacecraft’s new configuration.

Reading these numbers

A typical post picks up 342 interactions against 933K followers, an engagement rate of 0.037%. Measured over 20 original posts, its engagement rate beats 55% of 3,774 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 19K times each, and 1.80% of those impressions turn into an interaction.

What is NASA Goddard's engagement rate on X?
NASA Goddard (@NASAGoddard) has an engagement rate of 0.037%, based on the median interactions across 20 original posts from the last 30 days against 932,525 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.037%, NASA Goddard sits above the 25th percentile of the 36,521 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 @NASAGoddard have real engagement?
Its engagement rate beats 55% of the tracked X accounts closest to it in follower count (3,774 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 @NASAGoddard post?
Most posts go out around 15:00 UTC, and Wednesday is its busiest day, at roughly 2.2 posts per day across the measured window.
