How to Land a Rocket Launch ‘Space Jellyfish’

A space jellyfish is a rare and visually striking phenomenon that occurs during sunrise or sunset, when a rocket's exhaust plume rises over the Earth's curve and reflects sunlight. The plume can take on shapes resembling jellyfish, and the event is becoming more common due to increased launches, particularly from SpaceX. The last five years saw a record number of launches worldwide, with 2026 continuing this trend. SpaceX may attempt a first-ever orbital launch of Starship on September 15th, and launches along the Gulf of Mexico could make space jellyfish a common sight in the Gulf and Caribbean region.

• SpaceX's launches from the Florida Space Coast and Vandenberg Space Force Base in California are prime locations for observing space jellyfish.
• The 2015 MUOS-4 launch from Virginia Beach is an example of a space jellyfish.
• The 2025 Starlink morning launch from Virginia Beach is another example.

The phenomenon is supported by the launch schedules and the direction of the launch. A 2AM launch with a long window might be worth watching, as it could slip through the twilight to well past local sunrise.
