On the morning of October 13, 2026, SpaceX's Falcon 9 lifted off from Cape Canaveral at 6:33 a.m. EDT on the CRS-35 cargo mission to the International Space Station — and painted a glowing jellyfish across the pre-dawn sky, visible from Florida to the Carolinas. Thousands of phones captured it. The jellyfish effect is one of the most photogenic sights in spaceflight, and you need nothing more than a smartphone to photograph it well. The real challenge is being ready when it happens.

Step one is picking the right launch. The jellyfish appears only on twilight launches — roughly thirty to ninety minutes before sunrise or after sunset — when the ground is dark but the rocket's high-altitude plume is caught in sunlight. Follow a launch schedule tracker and filter for dawn or dusk windows; CRS-35's just-before-sunrise liftoff was textbook. Set alerts for any Falcon 9 or Starship flight in these windows, because the effect is most dramatic on launches heading northeast along the coast, which keep the plume in view longer.

Step two is location and preparation. Choose a spot with a clear view toward the launch direction and minimal nearby light — a beach, open field, or rooftop works — and arrive at least fifteen minutes early so your eyes dark-adapt and you can frame test shots of the horizon. Charge your phone fully, free up storage, and decide your composition in advance: a wide shot of the sky with a silhouetted foreground makes the glowing cloud look enormous and gives your photo context. Photographers chasing sky phenomena also study APOD's sonified Eagle Nebula pillars for ideas on presenting cosmic imagery in fresh ways.

Step three is the phone setup. Switch to night mode or a long-exposure camera app and mount the phone on a small tripod or prop it firmly against something stable — the plume evolves over minutes, and stability is what separates a glowing smear from a crisp, detailed jellyfish. Frame wide for the first shots, because the plume expands dramatically and a tight crop will cut off the tendrils. Tap to focus on the bright plume and drag exposure down slightly so the colors stay rich instead of washing out.

Step four is timing your sequence. Start shooting the moment the sky begins to glow, before the rocket is even visible — the earliest phase often shows the most saturated colors. Keep capturing frames as the plume expands and thins; within five to ten minutes the crisp jellyfish softens into a wispy streak, which photographs beautifully in its own right. If your phone supports it, shoot a short time-lapse of the whole event, then pull your favorite stills from the footage afterward.

Step five is the follow-up. Check the launch schedule again immediately after a sighting, because Falcon 9's rapid flight rate means another twilight window may come within days or weeks. Share your photos with local skywatching groups — comparing shots from different distances reveals how the plume's shape changes with viewing angle, and your image might help others understand what they saw. And if you are building a habit of chasing these sky shows, the slow-motion footage of a Starship launch is worth studying to see how launch plumes evolve second by second.
