STS-120 was a space shuttle mission to the International Space Station (ISS) that launched on 23 October 2007 from the Kennedy Space Center, Florida. The mission is also referred to as ISS-10A by the ISS program. STS-120 delivered the Harmony module and reconfigured a portion of the station in preparation for future assembly missions. STS-120 was flown by Space Shuttle Discovery, and was the twenty-third space shuttle mission to the ISS.
As commander of STS-120, Pamela Melroy became the second woman (after Eileen Collins) to command a space shuttle mission. Additionally, the Expedition 16 crew that received STS-120 was commanded by Peggy Whitson, the first female ISS commander. The flight of STS-120 thus became the first time two female mission commanders were in space at the same time.
Prior to the Space Shuttle Columbia disaster, the original crew manifest for STS-120 was:
The STS-120 mission patch was designed by Michael Foreman before he was reassigned to STS-123.
STS-120 delivered launch package 10A to the International Space Station (ISS). It consisted of the U.S. Harmony module (also known as Node 2), with four DC-to-DC Converter Unit (DDCU) racks and three Zero-g Storage Racks (ZSR) installed; a Power and Data Grapple Fixture (PDGF) for the station's robot arm, and a Shuttle Power Distribution Unit (SPDU). Harmony was built for NASA by Thales Alenia Space in Torino, Italy, as part of an agreement between NASA and the European Space Agency and was the first pressurized habitable module delivered to the station since the Pirs docking compartment was installed in August 2001.
