STS-127's fifth launch attempt, on 13 July 2009, was also scrubbed due to anvil clouds and lightning within of the launch site, which violated launch safety rules. STS-127 finally launched successfully on its sixth launch attempt, on 15 July 2009 at 18:03 EDT. Pieces of foam were observed falling off of the External Tank during the ascent, the same occurrence that had led to the loss of "Columbia" in 2003. However, "Endeavour" received only minor scuffs to its heat shield, the damage not enough to cause concern over reentry. The shuttle landed at Kennedy Space Center 16 days later at 10:48 EDT on 31 July 2009.
