NASA Armstrong engagement report
@NASAArmstrong - 515K followers on X
Measured over 6 original posts from a 30-day window, last computed on October 18, 2026.
Engagement
Early reading. We have captured 6 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 104 interactions against 515K followers, an engagement rate of 0.02%. Posts are seen about 5.0K times each, and 2.10% of those impressions turn into an interaction. That is about 0.969% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.33 posts a day over the last 30 days, though only 27% of days saw any activity at all. Most posts go out around 16:00 UTC, and Wednesday is the busiest day of the week. Of the 6 posts sampled, 100% carry an image or video and 83% link out. The account's strongest tracked post pulled 15K interactions, about 144x its own typical post. Only 6 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 16:00 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 | 83% 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.
- 83% 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 320 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.

Happy Birthday, Neil Armstrong! Before becoming an astronaut in 1962, Armstrong served as a research pilot here at NASA’s Armstrong Flight Research Center. As a project pilot on pioneering high-speed aircraft, including the iconic X-15, which reached speeds over 4,000 mph, he flew more than 200 different aircraft spanning jets, rockets, and helicopters. Today, we honor his enduring impact on aerospace research, space exploration, and aviation history. His legacy continues to inspire generations of explorers, innovators, and enthusiasts.

#OTD in 1961, Major Robert M. White was the first pilot to exceed Mach 5 in an aircraft. Flying the X-15, White reached an altitude of 107,700 feet and a speed of 3,603 miles per hour. The highly successful X-15 program provided valuable data that contributed to the development of the Mercury, Gemini, and Apollo spaceflight programs, as well as the Space Shuttle program. 🔗: https://t.co/dwcqInz7cm NASA History | NASA Aeronautics
