Spacewalker Oleg Kononenko is on the Strela boom getting ready for inspection work on the Soyuz crew vehicle.
Expedition 57 Flight Engineers Oleg Kononenko and Sergey Prokopyev of Roscosmos completed a spacewalk lasting 7 hours and 45 minutes.
The two cosmonauts opened the hatch to the Pirs docking compartment to begin the spacewalk at 10:59 a.m. EST. They re-entered the airlock and closed the hatch at 6:44 p.m. EST.
During the spacewalk, the two examined the external hull of the Russian Soyuz MS-09 spacecraft attached to the space station, took images, and applied a thermal blanket. They also retrieved science experiments from the Rassvet module before heading back inside.
Prokopyev, NASA astronaut Serena Auñón-Chancellor, and ESA (European Space Agency) astronaut Alexander Gerst are scheduled to depart the station in the Soyuz MS-09 at 8:42 p.m. Dec. 19, returning home to Earth after a six-and-half-month mission.
Kononenko, on his fourth spacewalk today, is designated extravehicular crew member 1 (EV1), and is wearing a spacesuit bearing red stripes. Prokopyev, on his second spacewalk, is wearing blue stripes and is designated extravehicular crew member 2 (EV2).
Coverage of the spacewalk continues on NASA Television and the agency’s website.

Spacewalkers Oleg Kononenko (left pic from February 2012) and Sergey Prokopyev (right pic from August 2018) will examine the Soyuz MS-09 spacecraft that will return three Expedition 57 crew members to Earth Dec. 19.
Over the course of about six hours, the duo will use this spacewalk to examine a section of the external hull of the Soyuz MS-09 spacecraft currently docked to station, and if time permits, retrieve external experiments.
In late August, a pressure leak occurred from the space station that was traced to the Soyuz. Within hours after finding the source of the leak, crew members sealed the hole and the station has since maintained steady pressure.
The cosmonauts will take samples of any residue found on the hull and take digital images of the area before placing a new thermal blanket over it. The samples and images will provide additional information that will aid the investigation in the cause of the pressure leak.

Dragon Attached to Station, Returns to Earth in January
Dec. 8, 2018: International Space Station Configuration. Six spaceships are attached at the space station including the U.S. resuppy ships Northrop Grumman Cygnus and the SpaceX Dragon; and Russia’s Progress 70 and Progress 71 resupply ships and the Soyuz MS-09 and MS-10 crew ships all from Roscosmos.
Three days after its launch from Florida, the SpaceX Dragon cargo spacecraft was installed on the Earth-facing side of the International Space Station’s Harmony module at 10:36 a.m. EST.
The 16th contracted commercial resupply mission from SpaceX delivers more than 5,600 pounds of research, crew supplies and hardware to the orbiting laboratory. Among the research it will bring to station, science investigations and technology demonstrations aboard Dragon include:
The Global Ecosystem Dynamics Investigation (GEDI) will provide high-quality laser ranging observations of the Earth’s forests and topography required to advance the understanding of important carbon and water cycling processes, biodiversity, and habitat. GEDI will be mounted on the Japanese Experiment Module’s Exposed Facility and provide the first high-resolution observations of forest vertical structure at a global scale. These observations will quantify the aboveground carbon stored in vegetation and changes that result from vegetation disturbance and recovery, the potential for forests to sequester carbon in the future, and habitat structure and its influence on habitat quality and biodiversity.
A small satellite deployment mechanism, called SlingShot, will be ride up in Dragon and then be installed in a Northrop Grumman Cygnus spacecraft prior to its departure from the space station. SlingShot can accommodate as many as 18 CubeSats of any format. After the Cygnus cargo ship departs from station, the spacecraft navigates to an altitude of 280 to 310 miles (an orbit higher than that of the space station) to deploy the satellites.
Robotic Refueling Mission-3 (RRM3) will demonstrate the first transfer and long-term storage of liquid methane, a cryogenic fluid, in microgravity. The ability to replenish and store cryogenic fluids, which can function as a fuel or coolant, will help enable long duration journeys to destinations, such as the Moon and Mars.
Growth of Large, Perfect Protein Crystals for Neutron Crystallography (Perfect Crystals) crystallizes an antioxidant protein found inside the human body to analyze its shape. This research may shed light on how the protein helps protect the human body from ionizing radiation and oxidants created as a byproduct of metabolism. For best results, analysis requires large crystals with minimal imperfections, which are more easily produced in the microgravity environment of the space station.
Dragon is scheduled to depart the station in January 2019 and return to Earth with more than 4,000 pounds of research, hardware and crew supplies.

The SpaceX Dragon cargo craft is moments way from being captured with the Canadarm2 robotic arm.
While the International Space Station was traveling about 250 miles over the Pacific Ocean north of Papua New Guinea, Expedition 57 Commander Alexander Gerst of ESA (European Space Agency) and Flight Engineer Serena Auñón-Chancellor, captured the Dragon spacecraft at 7:21 a.m. EST using the space station’s Canadarm2 robotic arm.
Ground controllers will now send commands to begin the robotic installation of the spacecraft on bottom of the station’s Harmony module. NASA Television coverage of installation is scheduled to begin at 9 a.m. Watch online at www.nasa.gov/live.
The Dragon lifted off on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida Wednesday, Dec 5 with more than 5,600 pounds of research, equipment, cargo and supplies that will support dozens of investigations aboard the orbiting laboratory.
The International Space Station is an accessible space laboratory with unparalleled capability that is increasing knowledge of engineering and physical sciences, biology, the Earth, and the universe through research and technology demonstrations and providing the foundation for continuing human spaceflight beyond low-Earth orbit. NASA’s human research is closing the gaps in current scientific understanding of how best to predict, assess, and solve the problems that humans encounter while living and working in space, and extend that knowledge to protect the women and men who will go forward to the Moon and Mars.
