After a #rocket #launch, the exhaust, often mostly water, can create a condensation trail, which is twisted by the wind. And when the Sun is just beyond the horizon, it can illuminate these trails high in the atmosphere in fantastic, #colorful ways. This #phenomenon is sometimes called a #launchjellyfish because the trail can expand in different ways depending on the #launchvehicle and weather conditions, sometimes taking the shape of a giant #jellyfish in the sky.
This trail was created by the a United Launch Alliance #ULA #DeltaIV Medium+ with a 5 meter fairing and 4 #GEM60 solid rocket boosters #SRBs, carrying #WGS5, the fifth Wideband Global #Satcom satellite for the US #DoD and international partners.
