Two astronauts switched their spacesuits to battery power this morning at 6:22 a.m. EST aboard the International Space Station to begin a spacewalk planned to last about six-and-a-half hours.

Expedition 50 Commander Shane Kimbrough and Flight Engineer Thomas Pesquet of ESA (European Space Agency) will install adapter plates and hook up electrical connections for the remaining three of six new lithium-ion batteries installed on the station’s starboard truss. Kimbrough is designated extravehicular crew member 1 (EV 1), wearing the suit bearing red stripes. Pesquet is designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes.

The new channel lithium-ion batteries installed Friday, Jan. 6 during the first spacewalk with Kimbrough and Flight Engineer Peggy Whitson of NASA are functioning properly and all electrical loads are being routed normally to systems through that power channel.

Earlier this week, the robotic ground controllers used the Canadian-built “Dextre” Special Purpose Dexterous Manipulator to move the three new lithium-ion batteries for today’s spacewalk into their slots in the Integrated Electronics Assembly. Engineers also moved one of the old nickel-hydrogen battery onto the HTV External Pallet for disposal and two others to one of Dextre’s arms for temporary stowage.

In all, nine old nickel-hydrogen batteries will be stowed on the external pallet for disposal when the HTV is deorbited to burn up in the Earth’s atmosphere later this month. The power channel for the last of the new batteries will be activated during the spacewalk after adapter plates are moved into place on the Integrated Electronics Assembly.

Watch the spacewalk on NASA TV and on the agency’s website.

Expedition 50 astronauts Shane Kimbrough and Thomas Pesquet are ready for their mission’s second spacewalk that starts Friday at 7 a.m. EST. The duo will wrap up power maintenance work to connect new lithium-ion batteries and install adapter plates. Kimbrough and NASA astronaut Peggy Whitson started that work last Friday during a six-hour, 32-minute spacewalk.

Both spacewalks complement the ongoing robotics work that started at the end of December. Ground controllers have been remotely-operating the Canadarm2 robotic arm and Dextre robotic hand to remove and stow the old nickel-hydrogen batteries and the install the new batteries.

The three cosmonauts have been staying focused on their set of Russian space research and lab maintenance. Station veterans Andrey Borisenko and Oleg Novitskiy collected blood samples for a pair human research studies looking at bone loss and stress responses caused by living in space. First-time station resident Sergy Ryzhikov explored chemical reactions caused by jet engine exhaust in the Earth’s upper atmosphere.

Six International Space Station crew members are heading in to the Thanksgiving holiday with human research activities and orbital lab maintenance.

NASA astronaut Peggy Whitson is the most experienced crew member in space right now getting ready to spend her third holiday season on orbit. Today, she stowed the tools used for space plumbing work done on Tuesday putting the Waste and Hygiene Compartment, the station’s toilet, back in service after a leak was discovered.

She and her new crewmates, Oleg Novitskiy from Roscosmos and Thomas Pesquet from the European Space Agency, are in their first week aboard the space station. They are getting used to their new home in space and familiarizing themselves with station emergency gear and procedures today. Whitson is beginning her third mission aboard the orbital complex while Novitskiy is starting his second mission. Pesquet is on his first mission and is France’s fourth astronaut to visit the space station.

The rest of the crew members, including Commander Shane Kimbrough and Flight Engineers Sergey Ryzhikov and Andrey Borisenko, are beginning their second month in space.

Today’s science work included collecting breath samples to help doctors understand how living in space affects bone marrow and blood cells. A new device that indirectly measures an astronaut’s intracranial pressure is being checked out today while the crew is also conducting eye exams.

The Expedition 49 crew is getting ready for the mid-October arrival of the Orbital ATK Cygnus spacecraft. The trio is also exploring human research and setting up a student Earth observation experiment.

First-time astronauts Kate Rubins and Takuya Onishi are brushing up on the robotic capture techniques necessary to grapple the Cygnus cargo craft. The Cygnus private space freighter is targeted to launch from Virginia between Oct. 9 and 13 and arrive at the International Space Station about 2-1/2 days later.

The duo will be inside the cupola at the robotics controls monitoring Cygnus’ arrival then capturing it with the 57.7 foot long Canadarm2. Ground controllers will then take over robotic operations and remotely attach Cygnus to the Unity module. Cygnus is delivering crew supplies, scientific research and hardware to the station crew members.

Before the pair began training today, Rubins sampled the station’s water for microbes and stowed the Hard to Wet Surfaces research gear. Onishi tested his fine motor skills on a mobile tablet device and logged his diet for the ENERGY experiment.

Commander Anatoly Ivanishin set up the Sally Ride EarthKAM experiment inside a Harmony module window today. The Earth imagery gear allows students to take pictures of Earth from space and share them on the internet.

SpaceX Dragon Splashes Down in Pacific Ocean

Baja California
The SpaceX Dragon splashed down on time off the Pacific coast of Baja Calfornia completing its ninth cargo mission. This photograph of Baja California and the Mexican coastline was taken Aug. 22, 2016 from the International Space Station.

SpaceX’s Dragon cargo craft splashed down in the Pacific Ocean at 11:47 a.m. EDT, approximately 326 miles west of Baja California, marking the end of the company’s ninth contracted cargo resupply mission to the International Space Station for NASA.

Following splashdown, Dragon will be recovered from the ocean and put on a ship for transportation to a port near Los Angeles, where some cargo including research will be removed and returned to NASA within 48 hours. Dragon will be prepared for a return journey to SpaceX’s test facility in McGregor, Texas, for processing. Dragon is currently the only space station resupply spacecraft able to return a significant amount of cargo to Earth at this time.

Dragon is returning more than 3,000 pounds of NASA cargo and science samples from a variety of technological and biological studies about the International Space Station. Results from the Heart Cells study, which investigated how heart muscle tissue contracts, grows and changes in microgravity, may help advance the study of heart disease and development of drugs and cell replacement therapy on Earth and on future space missions. Other experiments returning include tomato “space seeds” that were flown to station and will be planted on Earth as part of STEM education program with NanoRacks; Multi-Omics, which looked at impacts of space on astronauts’ immune systems; and OASIS, which studied the behavior of liquid crystals in microgravity, including their overall motion and merging of crystal layers.

Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins concluded their spacewalk at 2:02 EDT. During the five-hour and 58-minute spacewalk, the two NASA astronauts successfully installed the first of two international docking adapters (IDAs).

The IDAs will be used for the future arrivals of Boeing and SpaceX commercial crew spacecraft in development under NASA’s Commercial Crew Program. Commercial crew flights from Florida’s Space Coast to the International Space Station will restore America’s human launch capability and increase the time U.S. crews can dedicate to scientific research, which is helping prepare astronauts for deep space missions, including the journey to Mars.

Space station crew members have conducted 194 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 1,210 hours and 46 minutes working outside the station.
