Firefly Aerospace engagement report
@FireflySpace - 203K followers on X
Measured over 7 original posts from a 30-day window, last computed on October 8, 2026.
Engagement
Early reading. We have captured 7 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 487 interactions against 203K followers, an engagement rate of 0.239%. Posts are seen about 30K times each, and 1.61% of those impressions turn into an interaction. That is about 14.9% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.27 posts a day over the last 30 days, though only 23% of days saw any activity at all. Most posts go out around 12:00 UTC, and Wednesday is the busiest day of the week. Of the 7 posts sampled, 57% carry an image or video, 14% are part of a thread and 43% link out. The account's strongest tracked post pulled 1.4K interactions, about 2.8x its own typical post. Only 7 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 12:00 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 | 57% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 43% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 57% 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.
- 43% 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 384 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.

The next era of Moon exploration has begun! We're proud to announce a $75 million subcontract from @NASAJPL to deliver four drones above the Moon's south pole with our Elytra orbiter. In support of @NASA's MoonFall mission and larger Moon Base initiative, these drones will help map safe landing spots and resources for future Artemis missions.

We just reached another mile marker as we prepare for our journey to the Moon's far side! The team completed static load testing for our Elytra barrel and dual payload attach fitting that houses ESA's Lunar Pathfinder satellite. This rigorous testing at our Rocket Ranch verifies the structures can handle the extreme pressure they'll experience during launch. This achievement means all primary structures have passed acceptance testing for Blue Ghost Mission 2 and are ready to be assembled together!

Production is ramping up! From our engines to our composite structures, avionics, batteries, and harnesses, our teams are building faster and smarter. We’ve optimized assembly lines, expanded production space, upgraded manufacturing capabilities, and increased throughput across our spacecraft and launch product lines. Built reliably. Built for space.

Oh wait, that’s literally a rocket! 🚀 Two years ago, as students sang the national anthem, our Alpha rocket lit up the sky in the distance, creating an unforgettable moment. This weekend as we celebrate Independence Day, we’re reminded of 250 years of American innovation, ambition, and unity. Happy 4th of July from all of us at Firefly!

Blue Ghost on repeat! Firefly was awarded a $144 million @NASA CLPS contract to return to the Moon's near side and deliver three science instruments with our proven Blue Ghost lander. This marks our sixth contracted lunar mission, demonstrating rapid, repeatable access to the lunar surface. Read more here: https://t.co/3rCMWi0uCP

First the Moon, up next Mars! Firefly landed a $13 million subcontract from @NASAJPL to build and test the aeroshell for @NASA's SkyFall mission that will deploy three helicopters. Using our proven technologies and experience from the Moon, Firefly will help advance the next generation of Mars exploration. Read more here: https://t.co/swVtsDKCDo

Our Alpha rocket is going global! Yesterday Firefly and @SSCspace celebrated several milestones for Launch Complex 3C at the Esrange Space Centre in Sweden. With key infrastructure and regulatory agreements in place, we’re undergoing final pad construction and taking the next step towards a critical orbital launch capability from mainland Europe.

Our Automated Fiber Placement machine is winding the way to efficiency for our rockets and spacecraft! We were able to produce not just one, but three Elytra spacecraft structures at once. These structures were precision cut on our robotic power mill into their final shape. This approach allows us to reduce manufacturing time and improve efficiencies as we scale up our Elytra production line.

The next evolution of Alpha. Block II is the next-generation configuration of our Alpha rocket and the only operational U.S. 1-ton rocket. The striking white exterior isn't just for looks—it enhances thermal protection and is one of several engineering upgrades across the vehicle. ✅ 7-foot length increase ✅ In-house batteries & avionics ✅ Enhanced thermal protection ✅ Stronger carbon composite structures built with automated systems A bold new look. Built with purpose.

- What is Firefly Aerospace's engagement rate on X?
- Firefly Aerospace (@FireflySpace) has an engagement rate of 0.239%, based on the median interactions across 7 original posts from the last 30 days against 203,337 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.239%, Firefly Aerospace sits above the 50th percentile of the 204,956 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 @FireflySpace have real engagement?
- There is not yet enough sample to rank this account against others of its size.
- When does @FireflySpace post?
- Most posts go out around 12:00 UTC, and Wednesday is its busiest day, at roughly 0.27 posts per day across the measured window.
