October 23, 2007 11:38 a.m. EDT. Launch occurred on time with no delays.

The primary payload was the Harmony Node 2 module, to be installed on the International Space Station (ISS). There were four spacewalks during the mission. The first spacewalk was conducted on October 26, 2007 and lasted 6 hours, 14 minutes. Astronauts Parazynski and Wheelock installed the Harmony Node 2 module in its temporary location, readied theP6 Truss for its relocation, retrieved a failed radio communications antenna and snapped shut a window cover on the Harmony Node 2 module that had opened during launch.
The second spacewalk was conducted on October 28, 2007 and lasted 6 hours, 33 minutes. Astronaut Parazynski and ISS Flight Engineer Daniel Tani disconnected cables from the P6 Truss, and inspected the ISS starboard solar alpha rotary joint (SARJ). SARJ had shown increased friction and metal shavings were collected from underneath the joints multi-layer insulation covers. The astronauts also outfitted the Harmony Node 2 for its permanent installation.
The third spacewalk was conducted on October 30, 2007 and lasted 7 hours, 8 minutes. Astronauts Parazynski and Wheelock installed the P6 Truss Segment with its set of solar arrays to its permanent location. During the spacewalk, astronaut Wheelock noticed a small hole in the outer layer of his right glove thumb.
The fourth spacewalk was conducted on November 3, 2007 and lasted 7 hours, 19 minutes. Astronauts Parazynski and Wheelock successfully repaired a torn ISS solar array. A planned fifth spacewalk was cancelled due to the solar array repair, and this spacewalk was reassigned to the ISS crew.
