NASA astronauts Scott Kelly and Kjell Lindgren ended their spacewalk at 3:19 p.m. EDT with the repressurization of the U.S. Quest airlock, having completed most of the major tasks planned for their excursion outside the International Space Station.

Kelly and Lindgren applied a thermal cover on the Alpha Magnetic Spectrometer; applied grease to a number of components in one of the latching ends of the Canadarm2 robotic arm; and began work to rig power and data system cables for the future installation of a docking port to the station that will be used for the arrival of the Boeing Starliner CST-100 and SpaceX Crew Dragon spacecraft.

Greasing numerous parts of the robotic arm took somewhat longer than anticipated, and flight controllers chose to forego the lubrication of one component. However, engineers are satisfied the work that was completed sufficiently enhances the performance of the latching end effector. A lower priority task to reinstall a valve on the station will be assigned to crew members during a future spacewalk.

The 7-hour and 16-minute spacewalk was a first for both astronauts. Crew members have now spent a total of 1,184 hours and 16 minutes conducting space station assembly and maintenance during 189 spacewalks.

Kelly and Lindgren will venture outside the International Space Station again on Friday, Nov. 6. The two spacewalks were scheduled around milestones in space. Tomorrow, Kelly becomes the U.S. astronaut who has lived in space the longest during a single U.S. spaceflight, and Monday the crew celebrates the 15th year of a continuous human presence in space aboard the station.

During the second spacewalk, the astronauts will restore a truss cooling system to its original configuration following a 2012 spacewalk in which another team of astronauts attempted to isolate a leak of ammonia coolant. They also will top off ammonia on the station’s truss reservoirs. NASA Television coverage will begin at 5:45 a.m. EST ahead of the spacewalk’s planned start time of 7:10 a.m.

Approximately 2 hours and 30 minutes into today’s spacewalk, astronaut Kjell Lindgren successfully placed a thermal cover over the Alpha Magnetic Spectrometer (AMS) outside the International Space Station. First launched aboard the space shuttle Endeavour in May 2011, the AMS is collecting and analyzing billions of cosmic ray events and identifying dark matter.

Scott Kelly has been removing some insulation from a power switching unit on the station’s truss to facilitate its future robotic replacement.

Next up, Kelly will apply grease to several components of the 57.7 foot Canadarm2 robotic arm. Lindgren is working on routing power cables for the future installation of a docking port for commercial crew spacecraft.

NASA astronauts Scott Kelly and Kjell Lindgren will begin the first of two spacewalks Wednesday morning to service and upgrade the International Space Station. The duo have completed reviewing their procedures, preparing their U.S. spacesuits and organizing their tools inside the U.S. Quest airlock. NASA Television will cover the spacewalk live beginning at 6:30 a.m. EDT.

They will spend six hours and 30 minutes to cover the Alpha Magnetic Spectrometer with a thermal blanket, lubricate the leading edge of the Canadarm2 and route power and data cables for a future docking port. This will be the first spacewalk for both astronauts who will also be assisted from inside the station by Japanese astronaut Kimiya Yui. Monitoring the activities from the ground will be Tracy Caldwell, a veteran of three spacewalks.

Meanwhile, on the Russian side of the orbital laboratory, the trio of veteran cosmonauts stayed focused on their ongoing maintenance and science activities. Sergey Volkov spent time assisting Kelly and Lindgren today then looked at how the immune system is affected by stress in space. One-Year crew member Mikhail Kornienko explored blood circulation adaptation then worked on cargo transfers from the Progress 60 resupply ship. Oleg Kononenko studied material physics as he observed plasma crystals and liquid crystals.

Two astronauts are getting ready for a six-hour, 30-minute spacewalk Wednesday morning. They and the rest of the Expedition 45 crew also worked on international science and laboratory maintenance.

Commander Scott Kelly and Flight Engineer Kjell Lindgren are preparing for two spacewalks on Oct. 28 and Nov. 6 to upgrade and service the International Space Station. Lindgren was assisted by Japanese astronaut Kimiya Yui checking out the SAFER spacesuit jetpacks a spacewalker would use in the unlikely event they became untethered from the station. Kelly collected and organized the spacewalk tools he and Lindgren will use during both spacewalks. Watch a 3D animation illustrating the Oct. 28 spacewalk activities.

Kelly started his day with Mikhail Kornienko, his One-Year mission crewmate, as they swapped turns on the Fine Motor Skills experiment. Yui spent his morning stowing a small satellite deployer that ejected 14 Cubesats outside the Kibo lab module a few weeks ago.

Cosmonaut Sergey Volkov explored human metabolism in space and charged a satellite phone. Cosmonaut Oleg Kononenko looked at microgravity’s effects on a crew member’s cardiac and respiratory behavior before testing remotely controlling a rover on the ground from space.

The crew started their day checking out Cubesat gear and researching a wide variety of science to benefit humanity on and off Earth. Later, two astronauts tried on their spacesuits to ensure a good fit before next week’s spacewalk.

Commander Scott Kelly and Flight Engineer Kjell Lindgren were in the Kibo lab module Thursday morning inspecting and photographing a small satellite deployer mechanism. The mechanism failed to eject a pair of Cubesats two weeks ago and payload controllers are troubleshooting the issue.

During the afternoon, the duo got back together inside the U.S. Quest airlock and tried on the spacesuits they will wear on spacewalks scheduled for Oct. 28 and Nov. 6. They were assisted inside the airlock by Japanese astronaut Kimiya Yui and cosmonaut Sergey Volkov. Yui will guide the spacewalkers and operate the 57.7 foot Canadarm2 robotic arm during the spacewalks.

More human research took place today as the crew looked at brain adaptation and cognitive performance on the space station. The crew also explored sleep disturbances and changes in cardiac and respiratory behavior during long-term missions.

The International Space Station crew is gearing up for a couple of spacewalks to service and upgrade the orbital laboratory. Meanwhile, the crew is also working long-term life science to improve life on Earth and in future space crews.

The U.S. Quest airlock is getting busy as NASA astronauts Scott Kelly and Kjell Lindgren get their spacesuits and tools ready for a pair of spacewalks set for Oct. 28 and Nov. 26. They are checking their suit electronics and safety systems and also building custom tools.

The first spacewalk is set to last six-hours and 30-minutes after Kelly and Lindgren set their spacesuits to battery power. The duo will exit Quest to place a thermal cover over a dark matter detection experiment, lubricate the 57.7 foot Canadarm2 robotic and route power cables for a future docking port.

The entire crew still continued the work of on-orbit science, the primary purpose of the space station. Cosmonaut Mikhail Kornienko, along with Kelly and Lindgren performed cardiac scans with an ultrasound for the Ocular Health study. Japanese astronaut Kimiya Yui set up a mouse habitat inside the Cell Biology Experiment Facility.

The deployment of two Cubesats is on hold after they failed to eject a couple of weeks ago. Also, more spacesuit servicing and biomedical investigations took place today.

The deployer mechanism that ejected 14 of 16 Cubesats is back inside the Kibo laboratory module’s airlock. Two of the Cubesats did not deploy due to a secondary latch mechanism that hung up inside a deployer slot.

Japanese astronaut Kimiya Yui scrubbed cooling loops inside the spacesuits that NASA astronauts Scott Kelly and Kjell Lindgren will wear on two upcoming spacewalks. Lindgren also collected and organized spacewalk tools he and Kelly will use during the Oct. 28 and Nov. 6 spacewalks. The duo will exit the U.S. Quest airlock to service and upgrade hardware outside the International Space Station.

Cosmonaut Mikhail Kornienko joined Kelly, his One-Year crewmate, and Lindgren for Ocular Health eye exams in the afternoon. Veteran cosmonauts Sergey Volkov and Oleg Kononenko partnered up for two different experiments. They first studied heart and lung activity in microgravity then moved on to exploring using sound waves to determine the location of micrometeoroid impacts.
