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.
context_section_description: The Shuttle and station crews spent the day transferring cargo, and resting in preparation for Monday's departure of Discovery. Nespoli and Melroy spent some time in the morning speaking to the Italian media, and later in the day the crew had some off-duty time. Following the traditional farewell ceremony, the hatches were closed at 20:03 UTC. During the emotional ceremony, Anderson spoke to the ground crew, expressing his gratitude for their support during his 137 days as an Expedition crewmember.
  You all kept me safe, you've shown me unwavering patience and professionalism... And you've all overlooked my shortcomings, and it's my hope that maybe you've even had a few laughs along the way... What I'd like to say is: What we are doing here is very important for all of human kind. It's worth the risk, it's worth the cost, and you folks on the ground are the people who make it happen. So I want you to take pride in your work and constantly look toward the heavens, for it is there you will see your future. For all the flight control, training and engineering teams in Houston, Huntsville and Moscow... I say thank you, you are indeed the best and the brightest that our world has to offer.
