Did you see a gigantic, glowing jellyfish in the night sky early on Tuesday morning (Oct. 13)? If so, it’s not an alien invasion (sorry); it was SpaceX launching its latest mission to the International Space Station (ISS).
What is it?
Just before dawn on Tuesday (Oct. 13), a SpaceX Falcon 9 rocket lifted off from Cape Canaveral Space Force Station in Florida, carrying to space a robotic Dragon capsule filled with thousands of pounds of cargo.
It will take Dragon a couple of days to reach the orbiting lab. If all goes to plan, the capsule will autonomously dock with the ISS’ Harmony module around 11 a.m. EDT (1500 GMT) on Thursday (Oct. 15).
Why is it incredible?

Imagine you wake up early in the morning. Perhaps you’re rushing to get ready for work, or maybe you’re just having a quiet moment with your coffee in the pre-dawn twilight. Then imagine you look out the window and see what looks like a gigantic, glowing jellyfish made up of orange and blue light and gas stretching across much of the slowly brightening sky.
If you’re not expecting such a sight, or it’s your first time seeing the remnants of a rocket launch, this would probably catch you off-guard. But don’t worry; there isn’t anything dangerous about this sight.
This “jellyfish” is created by the water vapor and carbon dioxide that are expelled by the rocket after takeoff. In the cold upper skies, those gases start to freeze into ice crystals, flowing off of and behind the rocket. If a launch occurs around dusk or dawn, sunlight hits this flowing plume of frozen gases while the ground and skies remain mostly dark, resulting in a uniquely spectacular (albeit, unusual) view.
