NASA astronauts Scott Kelly and Kjell Lindgren are looking ahead to Friday morning’s spacewalk to return the port truss cooling system back to its original configuration after repair work completed in 2012. Japanese astronaut Kimiya Yui will assist the spacewalkers before they get out the door and coordinate their activities from inside the International Space Station.
Today, the trio reviewed the cooling system servicing spacewalk procedures and organized their tools. Kelly and Lindgren will work with ammonia fluid cables and tanks during the spacewalk scheduled for Friday at 7:10 a.m. EST. Yui joined the duo and trained for the possibility their spacesuits may come in contact with ammonia coolant flakes.
Today marks 15 years of continuous habitation aboard the International Space Station. Expedition 1, the first station crew, docked Nov. 2, 2000 after launching two days earlier inside the Soyuz TM-31 spacecraft.
The young space station at the time consisted of just three modules including the Zarya module, the Zvezda service module and the Unity module. Commander William Shepherd and Flight Engineers Sergei Krikalev and Yuri Gidzenko spent 141 days in space, saw two space shuttle missions and the addition of a solar array truss structure and the U.S. Destiny laboratory module.
The current six-member crew, Expedition 45, consists of NASA astronauts Scott Kelly and Kjell Lindgren, Japanese astronaut Kimiya Yui and veteran cosmonauts Sergey Volkov, Mikhail Kornienko and Oleg Kononenko. Kelly and Kornienko are spending nearly a year in space.
The crew worked a wide variety of lab maintenance and advanced science exploring how life adapts to long-term space missions with potential benefits to Earth-bound humans and future astronauts. Today they researched new exercise techniques and how living in space affects a crew member’s attitude.
The crew also explored how the station’s habitat affects the orbiting resident’s mental state and how lack of sleep and fatigue affects a crew member’s cognition. Another ongoing experiment that took place today researched the dynamic loads the space station experiences during spacecraft dockings, spacewalks and even crew exercise.
Kelly and Lindgren are inspecting their tethers today which keep spacewalkers attached to the International Space Station. They are also reviewing procedures for the upcoming spacewalk and organizing their tools.
Japanese astronaut Kimiya Yui, who is also the spacewalkers’ internal coordinator, worked in the Kibo lab module attaching science samples to an experiment platform. He then moved on to studying how plants grow in space without gravity to guide them.
On the Russian side of the orbital laboratory, the cosmonauts explored tools and acoustic methods to detect micrometeoroid impacts on the station. The veteran trio of Sergey Volkov, Mikhail Kornienko and Oleg Kononenko, also researched the physics of plasma crystals and how a crew member adapts to piloting a spacecraft.
Expedition 45 Commander Scott Kelly has been in space longer than any other NASA astronaut. Today he exceeds Michael Lopez-Alegria’s record of 215 days on a single spaceflight. He passed Michael Fincke’s record of 382 cumulative days in space on Oct. 16.
Kelly also completed his first spacewalk along with Flight Engineer Kjell Lindgren on Wednesday. The duo worked outside for seven hours and 16 minutes on a series of tasks to service and upgrade the International Space Station. They wrapped a dark matter detection experiment in a thermal blanket, lubricated the tip of the Canadarm2 robotic arm and then routed power and data cables for a future docking port.
Meanwhile, the crew is back at work today on advanced space science and routine laboratory maintenance. Japanese astronaut Kimiya Yui explored how plants grow without gravity to guide them. Kelly recorded his impressions of the space station’s living and working space for the Habitability study. Lindgren trained for the VIABLE experiment that researches microbe development on station surfaces.
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.
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 switched their spacesuits to battery power at 8:03 a.m. EDT, signifying the start of today’s planned 6-hour, 30-minute spacewalk. NASA Television is broadcasting the spacewalk at www.nasa.gov/nasatv.
Kelly is wearing a spacesuit with red stripes and is designated EV1. His helmet camera displays the number 18. Lindgren’s spacesuit is white without stripes; he is designated EV2. His helmet camera displays the number 17. This is the first spacewalk for both astronauts.
The first tasks for the astronauts will be to install a thermal cover over a dark matter detection experiment, the Alpha Magnetic Spectrometer, and to remove a piece of thermal insulation from a power switching unit to facilitate its robotic replacement in the future.

U.S. astronauts Scott Kelly and Kjell Lindgren will venture outside the space station’s Quest airlock on Wednesday, Oct. 28 to perform a spacewalk in support of space station assembly and maintenance, 189th of the space station. The six-and-a-half hour walk will be streamed live beginning at 6:30 am E.T. You can watch the spacewalk live on NASA TV, on the NASA app on your smartphone or follow live updates on @Space_Station Twitter.
The spacewalk is the 32nd U.S. spacewalk, and will focus on station upgrades and maintenance tasks, including installing a thermal cover on the Alpha Magnetic Spectrometer, which is a state-of-the-art particle physics detector that has been attached to the station since 2011. NASA TV coverage will begin at 6:30 a.m. ET, with the spacewalk scheduled to begin at 8:10 a.m.
Another spacewalk is scheduled for the pair on Nov. 6. That will be the 33rd U.S. spacewalk, and will attempt to restore the port truss ammonia cooling system to its original configuration. A spacewalk conducted in November 2012 tried to isolate a leak in the truss’ cooling supply, but the leak was subsequently traced to a different component. NASA TV coverage will begin at 5:45 a.m., with the spacewalk scheduled to begin at 7:10 a.m.
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.
