KENNEDY SPACE CENTER, FLA. -- NASA Node 2 module sits inside the Space Station Processing Facility highbay with its new name, Harmony, revealed. The name, Harmony, was chosen from an academic competition involving thousands of students in kindergarten through high school. The Node 2 Challenge required students to learn about the International Space Station, build a scale model of the module, and write an essay explaining their proposed name. This will be the first U.S. piece of the space station named by someone other than a NASA official. Node 2 is a pressurized module that will act as a connecting port and passageway to additional international science labs and supply spacecraft. It also will be a work platform for the station's robotic arm. The module is scheduled to fly on mission STS-120 aboard Space Shuttle Atlantis targeted for later this year.

KENNEDY SPACE CENTER, FLA. -- Service platforms surround Space Shuttle Atlantis as it sits in Highbay 1 inside the Vehicle Assembly Building, while repair work continues on the external tank. In late February, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation and minor surface damage to about 26 heat shield tiles on the shuttle's left wing. A new target launch date has not been determined, but teams will focus on preparing Atlantis for liftoff in late April on mission STS-117. Photo credit: NASA/Jack Pfaller

Astronaut George Zamka, STS-120 pilot, is seated at the pilot's station on the forward flight deck of the Space Shuttle Discovery during rendezvous and docking operations with the International Space Station (ISS). The STS-120 mission launched from Kennedy Space Center's launch pad 39A at 11:38:19 a.m. (EDT) on October 23, 2007. The crew also included Scott E. Parazynski, Douglas H. Wheelock, Stephanie D. Wilson, all mission specialists; Pamela A. Melroy, commander; Daniel M. Tani, Expedition 16 flight engineer; and Paolo A. Nespoli, mission specialist representing the European Space Agency (ESA). Major objectives included the installation of the P6 solar array of the port truss and delivery and installment of Harmony, the Italian-built U.S. Node 2 on the ISS.

These seven astronauts took a break from training to pose for the STS-120 crew portrait. Pictured from the left are astronauts Scott E. Parazynski, Douglas H. Wheelock, Stephanie D. Wilson, all mission specialists; George D. Zamka, pilot; Pamela A. Melroy, commander; Daniel M. Tani, Expedition 16 flight engineer; and Paolo A. Nespoli, mission specialist representing the European Space Agency (ESA). The crew members were attired in training versions of their shuttle launch and entry suits. Tani joined Expedition 16 as flight engineer after launching to the International Space Station (ISS) and is scheduled to return home on mission STS-122. STS-120 launched October 23, 2007 with the main objectives of installing the U.S. Node 2, Harmony, and the relocation and deployment of the P6 truss to its permanent location.

A photographer used a fisheye lens attached to an electronic still camera to record a series of photos of the Space Shuttle Discovery at the launch pad while the STS-120 crew was at Kennedy Space Center for the Terminal Countdown Demonstration Test in October 2007. The STS-120 mission launched from Kennedy Space Center's launch pad 39A at 11:38:19 a.m. (EDT) on October 23, 2007. The crew included Scott E. Parazynski, Douglas H. Wheelock, Stephanie D. Wilson, all mission specialists; George D. Zamka, pilot; Pamela A. Melroy, commander; Daniel M. Tani, Expedition 16 flight engineer; and Paolo A. Nespoli, mission specialist representing the European Space Agency (ESA).

Back dropped by Earth's horizon and the blackness of space, the Italian-built U.S. Node 2, Harmony, is featured in Space Shuttle Discovery's cargo bay during the STS-120 mission. This image was photographed by an Expedition 16 crew member on the International Space Station (ISS) while Discovery was docked with the station. The aluminum node is 7.2 meters (23.6 feet) long and 4.4 meters (14.5 feet) in diameter. Its pressurized volume is 75.5 cubic meters (2666 cubic feet), and its launch weight is approximately 14,288 kilograms (31,500 pounds). The installation of Harmony increases the living and working space inside the station to approximately 500 cubic meters (18,000 cubic feet). It also allows the addition of international laboratories from Europe and Japan to the station.

The STS-120 patch reflects the role of the mission in the future of the space program. The shuttle payload bay carries Node 2, Harmony, the doorway to the future international laboratory elements on the International Space Station (ISS). The star on the left represents the ISS; the red colored points represent the current location of the P6 solar array, furled and awaiting relocation when the crew arrives. During the mission, the crew will move P6 to its final home at the end of the port truss. The gold points represent the P6 solar array in its new location, unfurled and producing power for science and life support. On the right, the moon and Mars can be seen representing the future of NASA. The constellation Orion rises in the background, symbolizing NASA's new exploration vehicle. Through all, the shuttle rises up and away, leading the way to the future.
