A Falcon 9 rocket left Cape Canaveral before sunrise on October 13, 2026, and within minutes it had turned the sky into something that looked less like a launch and more like a bloom of glowing jellyfish drifting through the dark. The image spread fast across social media and local news stations from Florida to Washington, D.C. By midday, outlets including the Washington Post were running galleries of the glowing cloud, and drone footage shot above the St. Augustine Lighthouse by AccuWeather storm chaser Aaron Rigsby became one of the most shared clips of the event, as AccuWeather reported.
The rocket itself was almost incidental to the spectacle. What people actually saw was sunlight hitting an expanding plume of rocket exhaust at high altitude while the ground below sat in pre-dawn darkness, a lighting trick that has fooled sky watchers before and will again. But the scale of this sighting, stretching across half a dozen states and the nation’s capital, and the fact that it rode on a working NASA cargo mission rather than a test flight, makes it worth unpacking properly: what launched, why the plume glowed the way it did, and what the hardware involved tells us about where Falcon 9 sits in a launch market that keeps getting more crowded.

What Happened on October 13: CRS-35 Lifts Off From Cape Canaveral
The launch was SpaceX’s Falcon 9 carrying a Cargo Dragon spacecraft on NASA’s 35th Commercial Resupply Services mission, designated CRS-35. Liftoff from Cape Canaveral Space Force Station in Florida came at 6:33 a.m. EDT, according to multiple outlets covering the mission, including Fox 35 Orlando. The Cargo Dragon carried more than 6,300 pounds of supplies and hardware bound for the International Space Station, a routine but essential resupply run that keeps the orbiting laboratory stocked with everything from food and spare parts to active science payloads. That 6,300-plus-pound figure describes the cargo aboard Dragon, not the mass of the Falcon 9 itself, which is why the “6,300-lb launch” in the headline refers to the payload and not the rocket.
CRS-35 is one in a long-running series of SpaceX resupply flights for NASA that has become so routine it barely makes news on its own merits anymore. What changed this time was the lighting. Pre-dawn launches put the rocket high enough, fast enough, that its exhaust plume catches direct sunlight several minutes before sunrise reaches observers on the ground. The result, as it has in past twilight launches, was an eerie, expanding bloom of light that onlookers instantly nicknamed a jellyfish, tentacles and all.
The Physics Behind the Jellyfish Glow
None of this requires anything exotic from the rocket. It requires timing. During a twilight launch, the sun has not yet risen over the horizon as seen from the ground, but it has effectively “risen” for an object tens of miles up, because altitude pushes the horizon line further away. Once the rocket’s upper stage and its exhaust plume climb into that zone of sunlight while the observer below is still standing in darkness, the plume lights up like a lantern against a black sky.
Rocket exhaust at high altitude also behaves differently than it does near the ground. Thinner air lets the plume expand far more than it would at sea level, spreading the exhaust into a widening cloud rather than a tight column. Add in the way unburned propellant and ice crystals scatter light, and the plume takes on a soft, backlit glow instead of a hard, bright trail. Combine that spreading motion with a glowing core and faint streaks trailing below it, and the resemblance to a jellyfish body with dangling tentacles becomes obvious to anyone looking up.
This is a well-documented optical effect, not a malfunction or anything unusual about this particular Falcon 9 flight. Twilight and pre-dawn launches have produced similar glowing clouds during past SpaceX missions, and the same physics shows up with other rockets launched at the right time of day. What made the October 13 event notable was simply how far the plume was visible and how many people happened to be awake, outside, and looking in the right direction at 6:33 a.m.
Where Sky Watchers Caught the Glow
Reports of the glowing plume came in from a wide swath of the eastern United States. Observers in Florida had the closest view, naturally, but the sighting radius extended through the Southeast and into the Mid-Atlantic, with specific reports from Georgia, South Carolina, Tennessee, Missouri, and Washington, D.C. Fox 5 Atlanta ran a photo gallery from viewers across Georgia, while KFVS12 documented sightings as far away as the Missouri Heartland, hundreds of miles from the launch pad.
That geographic spread is itself a reminder of how visible a rocket plume becomes once it clears the densest part of the atmosphere. A Falcon 9 launch at ground level is a local event. The same launch’s upper-stage plume, lit by a sun that has not yet reached the ground, can become a regional one. It’s the same mechanism that made the Cargo Dragon portion of this mission visible as far north as Cincinnati, a sighting distance that would be almost impossible to explain without the altitude and lighting angle involved.
The Hardware Doing the Work: Falcon 9 and Cargo Dragon
Falcon 9 is SpaceX’s workhorse rocket, and the Cargo Dragon riding on top of it is the company’s purpose-built freighter for NASA resupply missions. Together they form the hardware backbone of the Commercial Resupply Services program, the contract structure NASA uses to keep the International Space Station supplied without operating its own fleet of cargo rockets. The pairing has flown often enough that a pre-dawn CRS mission barely raises an eyebrow among space-industry watchers, right up until the plume lights up the sky and turns a routine cargo run into a viral event.
That routineness is the point. NASA does not want its resupply missions to be exciting in the way a first-of-its-kind test flight is exciting. It wants them boring, repeatable, and on schedule, because a cargo shortfall on the space station is a genuine operational problem, not just a headline. The hardware behind CRS-35 reflects that priority: a proven rocket paired with a cargo spacecraft that has made this exact kind of run dozens of times before.
Inside CRS-35: NASA’s 35th Resupply Run to the Space Station
The “35” in CRS-35 is not a marketing number. It reflects three and a half decades’ worth of cumulative experience, spread across more than a decade of SpaceX-operated flights under the Commercial Resupply Services umbrella, in keeping the space station stocked. Each mission carries a mix of consumables, hardware replacements, and active science experiments, and this one was no exception, delivering over 6,300 pounds of supplies and equipment to the orbiting outpost.
This mission sits alongside other CRS-35 coverage already published on this site, including a detailed breakdown of the launch itself and its Cape Canaveral liftoff, as well as reporting on the specific science payloads riding along, such as LambdaVision’s ninth retina-tissue experiment aboard the station and NASA’s mini-brain and artificial retina research now underway in orbit. Those stories cover the mission’s cargo manifest and science goals. This one is about the hardware and the sky show that hardware produced.
Not the First Jellyfish: Twilight Launches Have Done This Before
Sky watchers and space photographers have reported glowing, jellyfish-like plumes after previous early-morning and dusk launches, including a Falcon 9 jellyfish over California on February 10, 2025, one over Florida on July 26, 2025, and one over Vandenberg on September 28, 2025, according to Wikipedia’s list of such events, though the October 13 CRS-35 event stands out for how widely it was reported across state lines in a single morning. The pattern is consistent: a launch timed close to sunrise or sunset, clear skies along the flight path, and a rocket climbing fast enough to reach sunlit altitude while observers remain in darkness below.
What has changed over the past few years is less the physics and more the audience. SpaceX now launches rockets often enough, and enough people now carry phone cameras capable of capturing a faint plume against a dark sky, that these twilight effects get documented and shared within minutes rather than fading as a local curiosity. ABC News 4 in South Carolina’s Lowcountry ran a full photo gallery submitted by viewers within hours of the launch, a turnaround that simply did not exist a decade ago.
Why Viral Sky Photos Matter for SpaceX
It would be easy to dismiss a glowing plume as a pretty picture with no business implications, but that undersells how much public goodwill matters to a launch provider that depends on government contracts, regulatory approval, and continued access to launch sites near populated areas. Every viral jellyfish photo is also free, favorable publicity for a company whose business model depends on flying often, close to population centers, and without generating local opposition to launch noise or airspace closures.
Routine cargo runs rarely get this kind of attention on their own. A resupply mission to the space station, however essential, does not typically trend the way a crewed launch or a dramatic landing attempt does. When a plume effect turns an otherwise unremarkable Tuesday morning cargo flight into a shared regional event, it reinforces the sense that rocket launches are now a normal, even welcome, part of the sky rather than a disruptive industrial event. That perception shift has real value for a company planning to keep increasing its launch cadence in the years ahead.
Competitive Landscape: Rival Launch Providers and Cadence
Falcon 9’s flight rate remains the defining advantage SpaceX holds over its rivals in the US launch market. United Launch Alliance, Blue Origin, and Rocket Lab all operate orbital-class rockets capable of reaching the space station’s orbit or beyond, but none currently matches Falcon 9’s combination of reusable boosters and flight frequency. Space.com reported that an August 2026 mission marked SpaceX’s 100th Falcon 9 flight of 2026, and a current fleet summary counts 695 physical Falcon 9 liftoffs by October 13, 2026. That gap matters directly for NASA’s resupply planning, because a launch provider that flies often and reliably is the one that gets picked to keep a space station stocked on a predictable schedule.
It also explains why a cargo mission like CRS-35 barely registers as news in its own right until something like a twilight lighting effect pushes it into public view. NASA currently splits its resupply contracts between SpaceX’s Cargo Dragon and Northrop Grumman’s Cygnus spacecraft, giving the agency redundancy in case either provider faces a delay. SpaceX’s higher flight cadence has made its side of that arrangement the more frequently exercised option, which is part of why Falcon 9 cargo runs happen often enough to occasionally collide with ideal twilight lighting conditions.
Market Impact: The Business Behind Resupply Missions
Commercial Resupply Services missions are not glamorous, but they are a dependable revenue stream for SpaceX and a core piece of how NASA keeps the space station operating through the 2020s. Each flight represents a fixed, contracted delivery of cargo mass to orbit, priced and scheduled well in advance, which gives SpaceX a predictable baseline of launch business even as its higher-profile Starship program continues development and testing on a separate track, including recent work detailed in coverage of Starship’s Ship 40 returning to Texas after time at sea.
That dual-track approach, a mature Falcon 9 and Cargo Dragon combination handling routine cargo work while Starship absorbs the risk of next-generation development, lets SpaceX keep NASA’s resupply schedule steady without pausing it to wait on a program that is still working toward full operational status. The steadiness of that cargo side of the business is exactly why a launch like CRS-35 can fly without major advance fanfare, right up until a plume lights up half the East Coast’s sky and turns it into the story of the day.

What Comes Next for SpaceX’s Resupply Schedule
CRS-35’s Cargo Dragon is now on its way to dock with the International Space Station, where its cargo will be unloaded and its science payloads activated over the coming weeks. NASA and SpaceX typically follow a resupply mission with a planned return flight, bringing completed experiments and station waste back down for recovery, though exact scheduling for that return has not been detailed publicly as of this writing.
For SpaceX, CRS-35 folds back into a launch cadence that also includes regular Starlink deployments, such as a recent Falcon 9 flight carrying 27 Starlink satellites, alongside national security and commercial customer launches such as the Bandwagon-5 rideshare mission on October 20, which carried 32 payloads. That mixed manifest is what keeps Falcon 9 flying often enough that a pre-dawn or dusk launch, and the glowing plume that comes with the right lighting conditions, is now a matter of when rather than if.
Predictions: What to Watch For
- Expect more viral “space jellyfish” sightings as SpaceX’s launch cadence keeps climbing, simply because more launches mean more chances for a plume to catch the right light at the right time.
- Local TV stations and weather accounts will likely keep building rapid-turnaround photo galleries from viewer submissions, since this event showed how quickly that content can be assembled and published.
- NASA’s Commercial Resupply Services program will almost certainly keep favoring the higher-cadence provider for routine cargo runs, reinforcing Falcon 9’s role as the default workhorse for ISS logistics.
- Rival launch providers chasing reusability and higher flight rates will face continued pressure to close the cadence gap, since contract awards for cargo and crew work increasingly reward providers that can fly on a predictable, frequent schedule.
- As SpaceX’s Starship program matures, expect NASA and SpaceX to eventually discuss folding larger cargo runs into that vehicle, though Falcon 9 and Cargo Dragon are likely to remain the primary resupply workhorse for the immediate future.
Frequently Asked Questions
What caused the “space jellyfish” seen on October 13, 2026?
A SpaceX Falcon 9 rocket launched NASA’s CRS-35 cargo mission at 6:33 a.m. EDT from Cape Canaveral. Sunlight hit the rocket’s expanding exhaust plume at high altitude while observers on the ground were still in darkness, creating a glowing, jellyfish-shaped cloud.
Where was the space jellyfish visible?
Reports came in from Florida, the broader Southeast, and the Mid-Atlantic, including specific sightings in Georgia, South Carolina, Tennessee, Missouri, and Washington, D.C.
What was CRS-35 carrying?
The Cargo Dragon spacecraft carried more than 6,300 pounds of supplies and hardware to the International Space Station as part of NASA’s 35th Commercial Resupply Services mission.
Is the jellyfish effect dangerous or a sign something went wrong?
No. It is a known optical effect tied to the timing of twilight and pre-dawn launches, not a malfunction. The same lighting conditions have produced similar glowing plumes during past launches.
Who captured the most widely shared footage of the event?
AccuWeather storm chaser Aaron Rigsby captured widely circulated drone footage of the glowing plume above the St. Augustine Lighthouse in Florida.
Why does Falcon 9 produce this effect more often than other rockets?
It is less about the rocket itself and more about flight frequency. Falcon 9 launches so often that it simply has more opportunities to fly during the narrow twilight windows that produce the jellyfish lighting effect.
Will the Cargo Dragon return to Earth?
Cargo Dragon missions typically return later with completed experiments and station waste, though specific return timing for this mission has not been detailed in public reporting as of this writing.
Does this affect NASA’s resupply schedule going forward?
No disruption has been reported. CRS-35 proceeded as planned, and the jellyfish effect was purely visual, tied to lighting conditions rather than any issue with the rocket, spacecraft, or mission timeline.
