STS-120 Mission Specialists Scott Parazynski (left) and Paolo Nespoli talk before their return to flight to Houston. A welcoming ceremony for the crew is planned at NASA's Hangar 276 on the south end of Ellington Field in Texas. On the 15-day mission, the STS-120 crew continued the construction of the station with the installation of the Harmony Node 2 module and the relocation of the P6 truss. They landed Nov. 7 at NASA's Kennedy Space Center.

While anchored to a foot restraint on the end of the Orbiter Boom Sensor System (OBSS), astronaut Scott Parazynski, STS-120 mission specialist, participated in the mission's fourth session of extravehicular activity (EVA) while Space Shuttle Discovery was docked with the International Space Station (ISS). During the 7-hour and 19-minute space walk, Parazynski cut a snagged wire and installed homemade stabilizers designed to strengthen the structure and stability of the damaged P6 4B solar array wing. Astronaut Doug Wheelock (out of frame), mission specialist, assisted from the truss by keeping an eye on the distance between Parazynski and the array. Once the repair was complete, flight controllers on the ground successfully completed the deployment of the array.

The main objective of the STS-100 mission, the sixth International Space Station (ISS) assembly flight, was the delivery and installation of the Canadian-built Space Station Remote Manipulator System (SSRMS), or Canadarm2. In this photograph, astronaut Scott E. Parazynski, mission specialist, works with cables associated with the robotic arm during one of two days of extravehicular activity (EVA). Both space walks were shared with Chris A. Hadfield, mission specialist representing the Canadian Space Agency (CSA), who is visible in the helmet visor of Parazynski. STS-100 launched April 19, 2001 aboard the Space Shuttle Orbiter Endeavour for an 11 day mission.

S120-E-007080 (28 Oct. 2007) --- Astronaut Scott Parazynski, STS-120 mission specialist, participates in the second of five scheduled sessions of extravehicular activity (EVA) as construction continues on the International Space Station. During the 6-hour, 33-minute spacewalk Parazynski and astronaut Daniel Tani (out of frame), Expedition 16 flight engineer, worked in tandem to disconnect cables from the P6 truss, allowing it to be removed from the Z1 truss. Tani also visually inspected the station's starboard Solar Alpha Rotary Joint (SARJ) and gathered samples of "shavings" he found under the joint's multi-layer insulation covers. Also the spacewalkers outfitted the Harmony module, mated the power and data grapple fixture and reconfigured connectors on the starboard 1 (S1) truss that will allow the radiator on S1 to be deployed from the ground later.

Hadfield, both mission specialists for STS-100, are pictured on the middeck of the Space Shuttle Endeavour in what is a scene very typical of nearly all the shuttle missions to the International Space Station (ISS). One common denominator of the shuttle-to-station missions is the large load of supplies and equipment transferred from Earth to the outpost, as well as the necessary inventory tasks that accompany the gear. This image was recorded by a fellow crew member using a digital still camera.

Parazynski, mission specialist, works at one of two areas onboard the Shuttle which support the Protein Crystal Growth (PCG) experiment. This particular section is called the Vapor Diffusion Apparatus (VDA), housed in a Single Locker Thermal Enclosure (STES). Together with the Crystal Observation System, housed in the Thermal Enclosure System (COS/TES) the VDA represents the continuing research into the structures of proteins and other macromolecules such as viruses. In addition to using the microgravity of space to grow high-quality protein crystals for structural analyses, the experiments are expected to help develop technologies and methods to improve the protein crystallization process on Earth as well as in space.
