NASA Goddard engagement report
@NASAGoddard - 933K followers on X
Measured over 16 original posts from a 30-day window, last computed on October 19, 2026.
Engagement
A typical post picks up 344 interactions against 933K followers, an engagement rate of 0.037%. Measured over 16 original posts, its engagement rate beats 54% of 20,182 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 13K times each, and 2.71% of those impressions turn into an interaction. That is about 1.36% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.5 posts a day over the last 30 days, with activity on roughly 63% of days. Most posts go out around 14:00 UTC, and Tuesday is the busiest day of the week. Of the 16 posts sampled, 94% carry an image or video, 63% are part of a thread and 50% link out. The account's strongest tracked post pulled 77K interactions, about 225x its own typical post.

Compared with accounts its own size
NASA Goddard's engagement rate beats 54% of the tracked X accounts closest to it in follower count (20,182 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 76% 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 204,491 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 14:00 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.

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 | 94% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 50% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 94% 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 288 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.

Here comes (a storm from) the Sun 🎶☀️ NASA’s PUNCH mission is sharpening forecasts with four satellites that monitor the Sun’s surface in 3D. Its first test predicted a storm’s arrival within 30 minutes, which is 10 times better than current methods. https://t.co/r2wJsZLNjg

A Statement from the Director of NASA’s Goddard Space Flight Center A Sept. 15 NPR story does not accurately reflect NASA’s Goddard Space Flight Center. Look no further than the Nancy Grace Roman Space Telescope. Roman launched last month ahead of schedule and on budget, is operating, healthy, and on its way to its permanent orbit. The story’s inaccurate claims that work on the telescope was affected do a disservice to the outstanding and dedicated Goddard team that actually brought the mission to fruition. Likewise, the GRITSS CubeSat mission launched on time in July and remains in its commissioning phase without issue. Regarding some of our future work, the DAVINCI mission development has been accelerated, and will be the first spacecraft to go to the surface of Venus in more than 40 years. It is our commitment to take complete accountability for every mission we develop and launch. That was the case when I started here 35 years ago, and it is still the case today. We at Goddard made hard, but necessary choices over the past several years to consolidate into a more effective campus footprint – and we are better positioned for the future because of it. The aerospace industry is changing rapidly, and Goddard will continue to lead through that change. We are focusing first on the capabilities that only NASA can provide – and because of our deliberate, strategic choices we will now be able to invest further in our most critical technologies and facilities in the coming years. I want to be absolutely clear: Goddard is not looking backward. We are moving forward, and as center director, I am confident in the exciting future that we are positioned for, with the vision and backing of NASA Administrator Jared Isaacman, to continue our legacy as NASA’s preeminent Earth and space science spaceflight center. I’ve had the privilege of being part of many missions over the years at Goddard, and am honored and excited to lead the center at this moment. With the dedication, perseverance, and brilliance of our workforce, my pledge to the Goddard team is that we will deliver nothing short of the best on behalf of the nation.

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

Massive stars don’t just live in their environment—they shape it. In nebula N44, stellar winds and supernovae from enormous stars carved out a giant central void, pushing cold gas into an outer shell where a new generation of stars are forming. https://t.co/oAa4meURmY https://t.co/0Jm1NwsdPe

Reading these numbers
A typical post picks up 344 interactions against 933K followers, an engagement rate of 0.037%. Measured over 16 original posts, its engagement rate beats 54% of 20,182 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 13K times each, and 2.71% of those impressions turn into an interaction. That is about 1.36% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.5 posts a day over the last 30 days, with activity on roughly 63% of days. Most posts go out around 14:00 UTC, and Tuesday is the busiest day of the week. Of the 16 posts sampled, 94% carry an image or video, 63% are part of a thread and 50% link out. The account's strongest tracked post pulled 77K interactions, about 225x its own typical post.
- 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 16 original posts from the last 30 days against 932,558 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 204,491 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 54% of the tracked X accounts closest to it in follower count (20,182 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 14:00 UTC, and Tuesday is its busiest day, at roughly 1.53 posts per day across the measured window.
