Lingering exhaust clouds of the Delta 2 rocket which launched the Mars-bound spacecraft Phoenix, as seen from Kennedy Space Center in Cape Canaveral, Fla on Aug. 4, 2007. Peter Smith, principal investigator for the Phoenix mission at the University of Arizona, said predawn winds blew the cloud into the shape of a mythical phoenix bird, which was lit by the sun before it rose over the horizon.
