STS-121 Flight Day 1 Highlights
S121-E-05138 (4 July 2006) --- This ice, floating freely several yards from Discovery, is believed to have come from the orbiter's main engine nozzles and was photographed by the STS-121 crew shortly after the spacecraft reached orbit on July 4. The presence of similar ice has been seen on previous missions and is a normal occurrence.
