Approximately 2 hours into today’s spacewalk, astronauts Tim Kopra and Tim Peake have completed the replacement of a failed voltage regulator that caused a loss of power to one of the station’s eight power channels last November.

The astronauts will now continue with additional tasks, including the routing of cables in advance of International Docking Adapter installment work to support U.S. commercial crew vehicles.

The solar arrays that convert energy to electricity on the space station are made of thousands of solar cells. Altogether, the arrays can generate 84 to 120 kilowatts of electricity — enough to provide power to more than 40 homes, and the space station’s electrical power system is connected by eight miles (12.9 kilometers) of wire.

U.S. EVA #35 Tasks

List of tasks to be performed during U.S. EVA #35 tomorrow at 7:55 a.m. EST.

Commander Scott Kelly and one-year crewmate Mikhail Kornienko continue their contribution to the fluid shifts study with the aid of Russian cosmonaut Sergey Volkov. Data from this long-term study hopes to reveal correlations between the distribution of fluid in the body and changes in vision during prolonged stays in microgravity.

Final preparations are underway for tomorrow’s spacewalk by Tim Kopra and Tim Peake to replace the failed Sequential Shunt Unit and regain the use of power channel 1B that went down on November 13. The 6 ½ hour spacewalk will also involve the spacewalkers deploying cables for the future installation of International Docking Adapters on Pressurized Mating Adapters that will accommodate the arrival of U.S. commercial crew vehicles.

Make sure to tune in to NASA TV tomorrow morning for a live look at U.S. EVA #35. Coverage begins at 6:30 a.m. EST: www.nasa.gov/nasatv

Expedition 46 Spacewalkers U.S. Spacewalk 35

NASA’s Timothy Kopra and ESA’s Timothy Peake will perform 6.5 hour spacewalk on January 15.

Preparation continues for Tim Peake and Tim Kopra for Friday’s 7:55 a.m. EST spacewalk. Today, they will be re-familiarizing themselves with the tools needed to perform the Sequential Shunt Unit (SSU) change out.

Aside from spacewalk preparation, Commander Scott Kelly and Tim Peake will also be setting up the JAXA Electrostatic Levitation Furnace (ELF) equipment. It will be installed into the Multi-purpose Small Payload Rack 2 (MSPR2) work volume inside of the Japanese Experiment Module (JEM).

Commander Scott Kelly and Mikhail Kornienko continue their fluid shift activities with help from Russian cosmonaut Sergey Volkov. Today’s activities are the third part of this experiment in which the Russian Chibis (Lower Body Negative Pressure – LBNP) is worn and ultrasound measurements of their eyes are taken.

Astronauts prepare for busy week of fluid shift experiments and end of week spacewalk

NASA astronauts Scott Kelly and Tim Kopra help ESA (European Space Agency) astronaut Tim Peake with his Extravehicular Mobility Unit (EMU) fit check.

Astronauts Tim Peake and Tim Kopra continue to prepare for their 6.5 hour spacewalk on Friday of this week. During the spacewalk they will be replacing a failed voltage regulator which will return power to one of the eight power channels.

Meanwhile, Commander Scott Kelly is gathering hardware for the fluid shifts experiment. Tomorrow, he and his one-year mission crewmate Mikhail Kornienko will be putting on the Russian Chibis suit, a lower body suit which redistributes fluids back to their legs. During this part of the experiment, they will be taking ultrasounds of their eyes to explore the correlation between body fluid distribution and potential changes in vision.

Russian cosmonaut Sergey Volkov has been taking readings for the Vibrolab experiment. Monitoring micro vibrations can help to understand how tiny movements affect science experiments on station.

Expedition 46 Crew Members

Four crew members of Expedition 46 pose for the camera after taking turns getting a quick haircut onboard the International Space Station. From left to right: Roscosmos cosmonauts Mikhail Kornienko and Sergey Volkov, NASA astronaut Timothy Kopra and ESA (European Space Agency) astronaut Timothy Peake.

Two astronauts were back at work today preparing the spacesuits and tools they will use next week during a maintenance spacewalk. The crew also wrapped up some plumbing work while continuing a wide variety of space science.

Flight Engineers Tim Kopra and Tim Peake checked out their U.S. spacesuits ensuring a good fit and readied their spacewalk tools. The duo from the United States and Britain will exit the International Space Station Jan. 15 to replace a failed voltage regulator and work on other maintenance tasks.

The station’s restroom, the Waste and Hygiene Compartment, is back in operation after some parts and cables were replaced. That work was completed after a leak was discovered.

Commander Scott Kelly joined his fellow One-Year crewmate Mikhail Kornienko for the ongoing Fluid Shifts study. That experiment explores how microgravity increases brain pressure pushing back on a crew member’s eye possibly affecting their vision.

Kelly observed a moment of silence this morning to mark the 5th anniversary of the shootings in Tucson, AZ. Rep. Gabrielle Giffords, married to Kelly’s twin brother and ex-astronaut Mark Kelly, was gravely wounded that day. Kelly, who was in space that day as commander of Expedition 26, was joined by his crewmates today for the silent moment.
