The SpaceX Starlink 10-40 mission deployed another 29 broadband internet satellites into low Earth orbit. The Falcon 9 rocket, soaring from Cape Canaveral, followed a north-easterly trajectory. This particular launch marked a milestone as the 600th Starlink satellite launched in 2026.
The "space jellyfish" effect occurs when the rocket's exhaust interacts with sunlight in the upper atmosphere, creating a vibrant, jellyfish-like visual. This phenomenon was widely photographed and shared across social media.
The mission utilized Falcon 9 first stage booster B1080, which has an impressive flight history, including multiple astronaut missions and cargo resupply missions for NASA. Its successful landing on the drone ship marked the 145th landing on that vessel and the 581st booster landing for SpaceX to date.
For those interested in witnessing future launches, key viewing locations along Florida's Space Coast include Playalinda Beach, Space View Park in Titusville, and various parks along Merritt Island and Cocoa Beach. Visibility is highly dependent on weather conditions.
