SpaceX CRS-35 Launch: Space Jellyfish at 6:33 AM [2026]

SpaceX is set to launch a Falcon 9 rocket carrying a Dragon cargo spacecraft from Florida’s Space Coast before sunrise on Tuesday, Oct. 13, 2026, and the predawn timing means sky-watchers from Jacksonville to West Palm Beach could catch a rare optical phenomenon nicknamed the “space jellyfish.” Liftoff is targeted for 6:33 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Space Force Station, according to Florida Today. The mission, designated CRS-35, is the latest in SpaceX’s long-running cargo resupply contract with NASA, and it is carrying more than 6,300 pounds of supplies and science hardware bound for the International Space Station.

What makes this particular SpaceX launch newsworthy beyond the routine cargo run is the lighting. A launch that lifts off in the narrow window around dawn or dusk, when the ground is still dark but the upper atmosphere is already catching sunlight, can produce a glowing, radial burst of color around the rocket’s exhaust plume. Photographers and residents across Central Florida have captured the effect after several 2026 launches, and outlets including Fox 35 Orlando, WKMG, the Orlando Sentinel, Island Free Press and the Post and Courier have all flagged Tuesday’s early-morning CRS-35 flight as a likely candidate for another appearance of the phenomenon.

SpaceX CRS-35: What’s launching and when

CRS-35 is a Commercial Resupply Services mission, the program under which SpaceX has flown cargo to the International Space Station for NASA for well over a decade using the Falcon 9 and Dragon hardware stack. For this flight, a Falcon 9 rocket is scheduled to lift off at 6:33 a.m. EDT on Tuesday, Oct. 13, 2026, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida, according to Florida Today’s launch tracker. The rocket is carrying a Dragon cargo spacecraft loaded with more than 6,300 pounds of supplies and science-investigation equipment for the astronauts aboard the orbiting laboratory, a figure NASA itself used in describing the mission.

NASA’s own description of the flight, as quoted in coverage of the launch, said that a SpaceX Dragon spacecraft on a Falcon 9 rocket would lift off from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida loaded with more than 6,300 pounds of supplies. That payload mix typically spans crew provisions, hardware upgrades for station systems and externally mounted or internally stowed science experiments that researchers on the ground have been waiting to get into orbit.

Because this is a Commercial Resupply Services flight and not a crewed mission, there is no astronaut aboard the Dragon capsule. The spacecraft is designed to dock autonomously with the station once it reaches orbit, a capability that has become routine for SpaceX’s cargo variant of Dragon since the company re-introduced propulsive docking-assist hardware and refined its rendezvous software over the past several resupply flights, as described in WFTV’s coverage of the mission.

The Falcon 9 and Dragon hardware behind the mission

The hardware doing the work on Tuesday morning is familiar to anyone who has followed SpaceX’s cargo program. The Falcon 9 is a two-stage, kerosene-and-liquid-oxygen rocket, and the company has spent years refining the booster so that individual first stages can be reused across dozens of flights. Dragon, the spacecraft riding on top, is the cargo-only configuration of the vehicle SpaceX also flies in a crewed version for NASA’s Commercial Crew Program. The cargo variant carries pressurized cargo in its cabin and can also carry unpressurized hardware in its trunk section, which is jettisoned before the capsule returns to Earth.

Space Launch Complex 40, the pad hosting Tuesday’s liftoff, is one of two Falcon 9 pads SpaceX operates on Florida’s Space Coast, the other being Launch Complex 39A at the neighboring Kennedy Space Center. SLC-40 has become the workhorse pad for Dragon cargo missions and most Starlink satellite deployments, and its proximity to the Atlantic coastline is part of why early-morning and dusk launches from the site are visible across such a wide swath of the Eastern Seaboard when weather cooperates.

What is a “space jellyfish,” exactly?

The space jellyfish effect is not a rare astronomical event in the way a comet or an aurora is. It is a predictable consequence of rocket exhaust physics and the timing of sunrise or sunset. The phenomenon occurs during the few minutes just before sunrise or just after sunset, when the ground below is still dark but sunlight is reaching the upper atmosphere where the rocket’s exhaust plume expands. As the plume billows outward in the near-vacuum of the upper atmosphere, it catches that high-altitude sunlight and glows, often with a translucent, tentacle-like bloom that expands and twists as the rocket climbs, which is how it earned its nickname.

A SpaceX official has previously described the visual directly. Jessica Jensen, a SpaceX official, explained the mechanics of the effect this way: “Basically, what’s happening is, it’s still dark outside, but you have the sun illuminating the plume as it’s in space.” Jensen has also used the nickname herself, saying she likes to refer to it as the space jellyfish that’s coming down after the spacecraft. Her comments, captured in coverage of an earlier predawn Dragon launch, remain the clearest on-record explanation of why the glow appears exactly when it does.

Florida residents have seen versions of this glow repeatedly through 2026. A July 9 Falcon 9 launch produced a widely photographed jellyfish effect that was visible as far away as Tallahassee and north Florida, according to the Tallahassee Democrat. Another launch window roughly six weeks later produced a similar glow that reportedly extended visibility into New York, New Jersey, Virginia and Delaware, per Florida Today’s reporting. Because Tuesday’s CRS-35 liftoff is scheduled for 6:33 a.m. EDT, well within the predawn window where the ground is dark but the sky at altitude is already catching the sun, meteorologists and local reporters have flagged it as another strong candidate, though neither NASA nor SpaceX has specifically predicted the effect for this particular flight.

Where the launch could be visible

Visibility for any Cape Canaveral launch depends on three variables: cloud cover, the rocket’s flight trajectory and how much ambient light is already in the sky at the moment of liftoff. For Tuesday’s CRS-35 mission, reports indicate visibility could extend from Jacksonville Beach in the north down through the Space Coast to West Palm Beach in the south, assuming clear skies and a cooperative trajectory. That is a stretch of Florida coastline spanning roughly 300 miles, which is typical for a clear-weather predawn Falcon 9 launch from Cape Canaveral.

Inland visibility is less certain and more weather-dependent. Past Falcon 9 launches from the Space Coast have been reported as visible in Tallahassee, more than 250 miles northwest of the pad, when skies were clear and the trajectory favored a northward-arcing path. Whether Tuesday’s CRS-35 ascent, which is headed toward the International Space Station’s orbital plane, produces similar inland visibility is not something NASA or SpaceX has confirmed, and local outlets have been careful to frame it as a possibility rather than a guarantee.

Even states well north of Florida have had a stake in SpaceX’s Space Coast launch cadence this year. As covered in our report on the International Space Station’s pass over New Jersey, the station itself, as distinct from the rocket’s exhaust plume, could be visible passing over New Jersey skies around the same week, a separate visibility event tied to the station’s orbital path rather than the glow of Tuesday’s liftoff.

How this launch compares to other Space Coast missions in 2026

Cape Canaveral’s launch cadence in 2026 has been dominated by two very different mission types: frequent Starlink satellite deployments and the periodic, higher-profile cargo and crew flights to the International Space Station. A Falcon 9 carrying 27 Starlink satellites lifted off from California earlier this year as part of that steady broadband-constellation buildout, a mission with a very different purpose and audience than Tuesday’s ISS resupply run. CRS-35 belongs to the smaller, slower cadence of cargo missions that NASA schedules against the station’s actual consumable needs and experiment timelines, rather than the near-weekly rhythm of Starlink launches. SpaceX’s broadband constellation has also drawn scrutiny well beyond Florida, including regulatory delays holding up Starlink’s India launch.

That distinction matters for sky-watchers. Starlink launches, because they happen so often, have become background noise to many Florida residents. A cargo mission to the space station, by contrast, draws more attention in local coverage precisely because it is rarer and because the destination — a laboratory with a human crew aboard — gives the mission a different kind of stakes. The predawn timing of CRS-35 adds a second layer of interest that a midday Starlink launch simply does not generate: the chance of the jellyfish glow.

Why SpaceX still flies NASA’s cargo missions

SpaceX’s cargo resupply contract with NASA dates back more than a decade, and it remains one of the steadiest revenue lines in the company’s launch business even as SpaceX has grown into a broadband operator through Starlink and a prospective deep-space launch provider through Starship. The Commercial Resupply Services program exists because the International Space Station still depends on regular deliveries of food, water, spare hardware and freshly built science experiments, none of which can be manufactured or indefinitely stored aboard the orbiting laboratory itself.

For SpaceX, missions like CRS-35 also serve as a continuing proving ground for the same Falcon 9 and Dragon hardware the company relies on for crewed flights. Every successful autonomous docking, every clean ascent and every recovered booster adds to the reliability record NASA and other customers weigh when deciding how much to trust the hardware with astronauts aboard. That track record has become part of why investors like Cathie Wood have floated eye-popping valuations for SpaceX ahead of any future public offering, and it feeds into the operational case analysts have made for the company’s next-generation Starship program.

Historical context: a decade-plus of Florida launch spectacles

Florida’s Space Coast has produced glowing exhaust-plume photographs for years, but the nickname “space jellyfish” has only become a mainstream talking point in local and national coverage within the past couple of years as launch frequency climbed. With SpaceX now flying Falcon 9 missions at a pace unimaginable a decade ago, the odds of any individual launch window lining up with dawn or dusk twilight have gone up simply because there are so many more launches on the calendar. What used to be an occasional curiosity captured by dedicated space photographers has become a recurring local news story that outlets like Florida Today, the Tallahassee Democrat and Fox 35 Orlando now cover on a near-monthly basis whenever a predawn or post-dusk window lines up.

That shift says as much about SpaceX’s operational tempo as it does about atmospheric optics. A company that once needed weeks to prepare a single Falcon 9 for flight now turns around boosters in days, and the sheer volume of twilight and predawn launch opportunities has turned a once-rare photographic event into something Central Florida residents have learned to watch for on their phones the night before a scheduled liftoff.

The science of the glow: plume physics in plain terms

The physical explanation boils down to altitude and light. Once a Falcon 9’s second stage is burning in the thin upper atmosphere, the rocket’s exhaust is no longer confined the way it would be at sea level. It expands rapidly into a wide, often symmetric plume of ice crystals and combustion byproducts. If the sun is below the horizon from the perspective of someone standing on the ground, but that same sun is still shining on the plume because the rocket is tens of miles higher up, the plume lights up independently of the dark sky around it. The effect is similar in principle to why high-altitude clouds can glow pink or orange well after sunset, except a rocket plume moves and twists as the vehicle accelerates, which produces the rippling, tentacled look that gives the jellyfish its name.

This is also why the effect is tied so specifically to launch timing rather than to any particular rocket. Any vehicle launching in that dawn or dusk twilight window from a site with a high enough second-stage burn altitude can, in principle, produce a similar glow. SpaceX’s Falcon 9 produces it often simply because the company launches so frequently and because its Florida missions regularly fall within that twilight window given NASA’s scheduling needs for space station resupply and crew rotation.

What happens after liftoff: Dragon’s trip to the station

Assuming an on-time 6:33 a.m. EDT liftoff, the Dragon spacecraft will spend roughly two days in transit before reaching the International Space Station. NASA’s stated plan for the mission describes an autonomous docking around 11 a.m. on Thursday, Oct. 15, at the space-facing port of the station’s Harmony module. That timeline is standard for Dragon cargo flights, which typically launch on a multi-day rendezvous profile rather than the same-day docking NASA sometimes uses for crewed Dragon missions.

Once docked, the station’s crew will spend the following weeks unloading the more than 6,300 pounds of cargo and integrating any new science hardware into ongoing experiments. Dragon’s cargo variant is also designed to return items to Earth, meaning the same capsule will eventually be loaded with completed experiments, hardware due for inspection on the ground and other return cargo before it undocks and splashes down off the Florida coast weeks later.

Weather and trajectory: the real wildcards

Launch visibility and the jellyfish effect both hinge on conditions that can change right up to the moment of liftoff. Cloud cover along the Space Coast or anywhere along the potential 300-mile viewing corridor between Jacksonville Beach and West Palm Beach can block the view entirely, even if the plume itself is glowing as expected. Florida’s October weather pattern, which can bring overnight cloud banks rolling in off the Atlantic, adds genuine uncertainty to any specific viewing prediction made the day before a launch.

Trajectory plays a role too. A Falcon 9 heading to the International Space Station’s orbital inclination follows a specific flight path up the Eastern Seaboard, which is part of why past CRS missions have occasionally been visible as far north as New Jersey and New York. But a slightly different launch azimuth, even by a few degrees, can change which coastal communities end up with a clear line of sight to the ascending rocket and its glowing plume.

Market and industry impact of a crowded launch calendar

For the commercial space industry, missions like CRS-35 are less about headline-grabbing new hardware and more about proving that high-frequency, reliable launch has become the normal state of business for SpaceX’s Florida operations. Every additional cargo flight reinforces the operational case investors and NASA officials have made for SpaceX’s broader valuation story, which has become a talking point of its own as analysts debate the company’s eventual public market prospects, including Morgan Stanley’s bullish read on SpaceX’s Starship progress. A steady drumbeat of successful Falcon 9 and Dragon missions, even routine cargo runs, is part of the track record underpinning that valuation debate. SpaceX’s reliability has also drawn comparisons to newer entrants like Europe’s Isar Aerospace, which is still working to match SpaceX’s launch cadence.

There is also a quieter economic dimension tied to local tourism and media attention. Each widely visible or photogenic Space Coast launch, jellyfish effect or not, draws visitors to Florida’s beaches before dawn and generates a fresh wave of local and regional news coverage, from Florida Today’s live launch trackers to television segments on WKMG and Fox 35 Orlando. That attention has become a modest but real economic multiplier for Brevard County’s tourism and hospitality sector, which has increasingly built marketing around “launch viewing” as a visitor draw in its own right.

Predictions: what to expect from Florida’s launch calendar

Expect more predawn and post-dusk Falcon 9 launches to produce jellyfish-effect coverage through the rest of 2026, simply because SpaceX’s Florida launch cadence shows no sign of slowing.
Local Florida outlets will likely continue publishing same-day “will it be visible” guides ahead of each twilight-window launch, mirroring the format used for Tuesday’s CRS-35 coverage.
NASA’s cargo resupply cadence to the International Space Station is likely to continue on a roughly similar multi-week rhythm, keeping missions like CRS-35 a recurring rather than one-off news event.
Visibility reports stretching hundreds of miles from Cape Canaveral, as seen with past launches reaching Tallahassee, New Jersey and New York, will likely keep happening on especially clear mornings or evenings.
Continued high-frequency, reliable Falcon 9 and Dragon flights will likely keep feeding into broader financial and industry narratives about SpaceX’s operational track record.

How to watch the SpaceX CRS-35 launch

For anyone hoping to catch the liftoff in person, the advice from Florida-based outlets covering the Space Coast consistently comes down to the same basics: find an unobstructed eastern horizon, get into position well before the 6:33 a.m. EDT target time, and check for last-minute scrubs, since weather or technical holds can push a launch by minutes, hours or days. Coastal viewing spots along the Atlantic side of Florida tend to offer the clearest sightlines, while inland viewers further from the coast are more dependent on favorable trajectory and clear skies to catch any part of the ascent, let alone the jellyfish glow itself.

NASA and SpaceX typically provide livestream coverage of Commercial Resupply Services launches, which remains the most reliable way to watch regardless of weather or location, though it does not replicate the experience of seeing the glowing plume firsthand from the ground.
