SpaceX Falcon 9 Launch Creates Stunning Space Jellyfish Over Florida Skies

Malcolm Denemark was already in position before sunrise on March 4, framing a derelict boat just offshore north of the Beachline and west of the Banana River bridge as foreground when the SpaceX Falcon 9 lifted off at 5:52 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station. The result, which Florida Today named its Photo of the Week, was exactly what experienced launch photographers stake out in the dark waiting for: a full-blown space jellyfish. Denemark called it "worth getting up for."

The Starlink 10-40 mission was carrying 29 broadband Starlink satellites into low-Earth orbit, but for anyone watching from the Space Coast that morning, the payload was almost beside the point. Within minutes of liftoff, the Falcon 9's exhaust plume expanded into a luminous, billowing shape that glowed against the still-dark sky. Ken Kremer, photographing from Titusville, described watching "the growing space jellyfish and separation of the Falcon 9 first and second stages" simultaneously. The timing was the key ingredient: 5:52 a.m. put the rocket in the air just as sunlight was reaching the upper atmosphere but the ground remained dark.

The physics behind the effect is straightforward once you know what to look for. FOX 35 meteorologist Brooks Garner explained that "the space jellyfish phenomenon forms due to the sunlight high in the atmosphere reflecting off the exhaust from the rocket." The more detailed mechanism involves crystallization: exhaust particles and water vapor freeze in the cold upper atmosphere, and those ice crystals then catch and reflect sunlight that hasn't yet reached the surface. The result is a structure that glows with pastel colors while everything below it is still in shadow, which is exactly the pre-dawn window that makes dawn and dusk launches so worth chasing with a camera.

Coverage spread quickly across the state. Bay News 9 reported that most of the Tampa Bay area had clear skies and picked up the jellyfish from that side of Florida, including a viewer photo from Michelle Lombardo shot on Gulf Boulevard between Bellair Bridge and Sandkey Bridge in Pinellas County. Residents in Tallahassee reportedly couldn't believe what they were seeing. Garner noted the effect was likely visible as far north as Georgia and along the U.S. northeastern coast, consistent with the rocket's northeasterly trajectory up the East Coast into virtually clear skies.

On the technical side, this was no rookie booster. The first stage, tail number B1080, flew for the 25th time before touching down successfully on the ASOG droneship positioned off the coast of South Carolina roughly eight minutes after liftoff.

This kind of shot has a short history but a passionate following. People magazine referenced a similar jellyfish from a May 2022 Falcon 9 launch out of Kennedy Space Center at 5:40 a.m., when photographer Kyle Morgan grabbed a frame from his favorite spot on Jekyll Island almost on a whim. "I instantly knew it was going to be a good photo but had no idea it would get the attention it has," Morgan said at the time.

With Starlink launches now running at a pace that makes booster flight 25 sound almost routine, the pre-dawn jellyfish has become one of the more repeatable grand slams in launch photography. The formula is simple: check the liftoff time against sunrise, pick a foreground that gives the shot a sense of place, and don't sleep in. Denemark's boat says everything about why compositional preparation matters as much as the phenomenon itself.
