A pair of spacewalkers are conducting final reviews as they get ready for Wednesday morning’s spacewalk scheduled to start at 7:10 a.m. EST. They will be assisted by Italian astronaut Samantha Cristoforetti who will be the spacewalk choreographer and robotic arm operator.
NASA astronauts Barry Wilmore and Terry Virts will go outside for more cable routing work and lubrication work on the Canadarm2. This will be the second in a series of three spacewalks meant to ready the International Space Station for a pair of International Docking Adapters. The third will be Sunday morning.
The duo will also prepare the Tranquility module for the relocation of the Permanent Multipurpose Module. They are also readying the station for the new Bigelow Expandable Activity Module set to arrive later this year.
The three cosmonauts focused on maintenance tasks and their set of microgravity science to benefit life on Earth and future crews. Cristoforetti also worked on maintenance and science work in between her spacewalk preparations.
Ground controllers have maneuvered the space station’s large robotic arm Canadarm2 in place for work planned for Wednesday’s spacewalk. Spacewalkers Barry Wilmore and Terry Virts will start their second spacewalk at 7:10 a.m. EST to lay more cables and lubricate one of Canadarm2’s two latching end effectors, which serve as tip or base for the robotic arm. They will also prepare the Tranquility module for the relocation of the Permanent Multipurpose Module and the new Bigelow Expanded Activity Module later this year.
While the duo is reviewing its procedures and getting its tools and spacesuits ready, Italian astronaut Samantha Cristoforetti worked a variety of advanced life science and high-flying plumbing work. She wore gear for the Drain Brain experiment that studies how blood flows from the brain back to the heart in microgravity.
NASA astronauts Barry Wilmore and Terry Virts ended their spacewalk at 2:26 p.m. EST with the repressurization of the Quest airlock. Wilmore and Virts completed all the scheduled tasks for today and one get ahead task. They rigged a series of power and data cables at the forward end of the Harmony module and Pressurized Mating Adapter-2 and routed 340 of 360 feet of cable. The cable routing work is part of a reconfiguration of station systems and modules to accommodate the delivery of new docking adapters that commercial crew vehicles will use later this decade to deliver astronauts to the orbital laboratory.
The 6-hour, 41-minute spacewalk was the first for Virts. Wilmore now has spent 13 hours and 15 minutes in the void of space during two spacewalks. The spacewalk began this morning at 7:45 a.m. Astronauts have now spent a total of 1,159 hours and 8 minutes conducting space station assembly and maintenance during 185 spacewalks.
The duo will venture outside the space station again on Wednesday, Feb. 25, to deploy two more cables and lubricate the end of the space station’s robotic arm. NASA TV coverage will begin at 6 a.m. Wednesday ahead of a planned 7:10 a.m. start time for the spacewalk.
Approximately 2 hours and 30 minutes into today’s spacewalk, astronauts Barry Wilmore and Terry Virts have finished attaching several new cables on the port side of Pressurized Mating Adapter-2. The duo will reinstall a debris shield before moving to attach another new cable on the starboard side and route additional cables during their remaining time outside the International Space Station.
The crew is routing more than 300 feet of cable during today’s spacewalk and a second one planned for Wednesday as part of a reconfiguration of the station to enable U.S. commercial crew vehicles under development to dock to the space station in the coming years.
NASA astronauts Barry Wilmore and Terry Virts switched their spacesuits to battery power at 7:45 a.m. EST, signifying the start of today’s planned 6-hour, 30-minute spacewalk.
Wilmore and Virts will attach power and data cables to the port and starboard sides of Pressurized Mating Adapter-2 at the forward end of the Harmony module where the first of two International Docking Adapters will be installed later this year. Boeing built the two new docking adapters, and they will be delivered to the station on a pair of SpaceX Dragon cargo spacecraft this year. Boeing’s Crew Space Transportation (CST)-100 and SpaceX’s Crew Dragon will use the adapters to deliver astronauts to the space station later this decade.
Wilmore is wearing a spacesuit with red stripes and is designated EV1. His helmet camera displays the number 18. Virts is wearing a spacesuit with no stripes and is designated EV2. His helmet camera displays the number 20. This is second spacewalk for Wilmore and the first for Virts. It is the 185th spacewalk in support of space station assembly and maintenance.
NASA Television will provide live coverage of tomorrow’s U.S. spacewalk conducted from the International Space Station beginning at 6 a.m. EST. The spacewalk is scheduled to begin at 7:10 a.m. and run about 6 1/2 hours.
Expedition 42 Commander Barry Wilmore and Flight Engineer Terry Virts will venture outside the orbital complex in the first of three spacewalks in the coming days to prepare cables and communications gear for new docking ports that will allow future crews launching from Florida on U.S. commercial spacecraft to dock to the space station.

NASA astronauts Barry Wilmore and Terry Virts are counting down to the first of three assembly spacewalks set to begin Friday at 7:10 a.m. EST. The duo checked out their rescue jet packs they would use in the unlikely event they became untethered from the International Space Station. The spacewalks will prepare the station for new commercial crew vehicle docking ports.
The latest supply ship to dock to the orbital lab, Progress 58, had its hatches opened Wednesday morning, following its Tuesday arrival. The Expedition 42 crew members will now begin unloading several tons of food and supplies that will replenish the station residents for the next few months.
Meanwhile, the six-member crew continued the International Partners’ mission of conducting advanced microgravity science. Ultrasound eye scans and blood pressure checks were conducted with remote guidance from doctors on the ground today. The crew also studied cell cultures grown on orbit and explored techniques to improve Earth observation photography.
The Expedition 41 crew is working advanced microgravity science while a pair of space freighters await launch. Orbital Sciences’ Cygnus is set for a 6:22 p.m. EDT launch today while Russia’s ISS Progress 57 will begin a six-hour trip to the station at 3:09 a.m. Wednesday.
NASA astronauts Reid Wiseman and Barry Wilmore reviewed operations for the Rodent Research study. German astronaut Alexander Gerst, from the European Space Agency, had a medical exam and worked a variety of science experiments.
The cosmonauts worked on their complement of Russian science and maintenance. Alexander Samokutyaev collected his blood and saliva samples and stowed them in a science freezer for later analysis on the ground. Commander Max Suraev began preparing for his Nov. 9 departure while finishing cleanup work after an Oct. 22 spacewalk. Elena Serova assisted her fellow cosmonauts with science and departure work.
Cosmonauts Max Suraev and Alexander Samokutyaev are working on their Russian Orlan spacesuits after Wednesday’s three-hour, 38-minute spacewalk. Elena Serova, Russia’s first female cosmonaut to live and work aboard the International Space Station, worked maintenance, checked the station’s air and collected radiation readings.
Astronauts Reid Wiseman and Alexander Gerst took turns Thursday scanning each other’s eyes with an Ultrasound. NASA astronaut Barry Wilmore checked out a hardware and control panel that will be used to communicate with the Cygnus private space freighter after it launches Oct. 27.
