the station giving the shuttle crew an opportunity to photograph the station's current configuration in all directions. Then a final separation burn was completed at 3:09 pm EDT. July 29 (Flight Day 15) The OBSS was grappled by the shuttle's robotic arm and used to inspect Endeavours thermal protection system for damage from orbital debris. The imagery will be analyzed to clear the shuttle for reentry. Meanwhile, the foam loss on the external tank was initially attributed to substrate contamination ahead of the application of the foam. Later during the processing of STS-128, voids in the foam was highlighted as a trigger for the shedding. The air trapped in the voids could have expanded due to the high temperatures generated during ascent thus breaking the foam. July 30 (Flight Day 16) The crew checked out the shuttle's systems for the landing, and successfully deployed the DRAGONSat and ANDE-2 satellites. The shuttle was cleared for reentry, with the TPS imagery showing no concerns. The shuttle tracked two chances of landing at KSC on July 31, and could land no later due to its limited carbon dioxide-scrubbing LiOH supply. July 31 (Flight Day 17, Landing) After a 16-day mission, Endeavour'' landed successfully at Kennedy Space Center at 10:48 EDT on July 31, 2009. The landing had to be undertaken before August 1, due to -scrubbing lithium hydroxide limitations. There were two opportunities to land on July 31, of which the first was ultimately utilized. EVAs Five spacewalks were conducted during STS-127. Wake-up calls NASA began a tradition of playing music to astronauts during the Gemini program, and first used music to wake up a flight crew during Apollo 15. Each track is specially chosen, often by the astronauts' families, and usually has a special meaning to an individual member of the crew, or is applicable to their daily activities.
