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 TV Providing Live Coverage of Saturday Spacewalk

ISS042E277380 (02/16/2015) — U.S. Astronaut Terry Virts, Flight Engineer for Expedition 42 on the International Space Station Feb. 16, 2015 checks out his spacesuit in preparation for the upcoming Extracurricular Activity (EVA) or Spacewalk for installation of a new port. This port will be for the commercial spacecraft as well as other craft in the future.

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 preparing to ready the International Space Station for a pair of international docking adapters (IDAs) that will allow future commercial crew vehicles to dock. The duo is almost set to start a series of three spacewalks routing cables and preparing the Canadarm2 for the installation of the IDAs to be delivered later this year.

The first spacewalk is now set to begin Saturday at 7:10 a.m. EST with NASA TV live coverage starting at 6 a.m. The second and third spacewalks are planned for Feb. 25 and March 1, both beginning at 7:10 a.m.

Amidst the spacewalk preparations, the Expedition 42 crew members continued ongoing advanced microgravity science benefiting life on Earth and current and future crew members. The crew looked at stem growth for the Aniso Tubule botany experiment, cell cultures grown on orbit and a crew member’s cardiac activity during long-duration missions.

Astronauts Preparing for Friday Spacewalk

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.

Progress 58 Docks to Station’s Zvezda Service Module

Traveling about 257 miles above the Atlantic Ocean northeast of Puerto Rico, the unpiloted Progress 58 Russian cargo ship docked at 11:57 a.m. EST to the rear port of the Zvezda service module of the International Space Station. The craft is delivering three tons of food, fuel, supplies and experiment hardware to the six crew members aboard the orbital laboratory. Progress 58 is scheduled to remain docked to the space station until August.

Meanwhile, astronauts in the U.S. segment of the station are reviewing procedures for a trio of spacewalks. The first is set to begin Friday at 7:10 a.m. Spacewalkers Barry Wilmore and Terry Virts will exit the orbital lab to set the stage for a pair of new commercial crew vehicle docking ports to be installed later this year.

Outside the station on Sunday, robotics controllers on the ground maneuvered the Canadarm2 with the Dextre attached to remove and replace a faulty Remote Power Controller Module (RPCM). The RPCM provides backup commanding capability to the port Thermal Radiator Rotating Joint.

Marking an end to the 7-year era of European space freighter supply to the International Space Station, ESA’s (European Space Agency) “Georges Lemaitre” cargo vehicle entered the Earth’s atmosphere and burned up over the Pacific Ocean around 12:12 p.m. Central time Sunday following a pair of engine firings that first lowered the ATV-5’s orbit, then enabled it to drop out of orbit for its fiery entry into the Earth’s atmosphere. The end to the ATV came one day after it undocked from the aft port of the Zvezda Service Module. After losing telemetry from the vehicle, ATV flight controllers at the ATV Control Center in Toulouse, France offered their thanks to the Flight Directors at Mission Control, Houston and the Russian Mission Control Center in Korolev, Russia for the years of support during the ATV program, and offered best wishes for the future years of ISS operations.

Although the entry smoke trail could not been seen on ISS external cameras, Expedition 42 Commander Barry Wilmore of NASA radioed down that he could see the plasma trail as ATV descended into the atmosphere and documented its demise with still and video cameras.

Meanwhile, at the Baikonur Cosmodrome in Kazakhstan, the Russian ISS Progress 58 cargo craft rolled to its launch pad in frozen fog and temperatures hovering around 18 degrees for its launch Tuesday morning to the station to deliver more than three tons of food, fuel and supplies. Launch is scheduled at 5 a.m. Central time, with docking to the aft port of Zvezda planned at 10:58 a.m. Central time.

Europe’s ATV-5 Leaves Station

ESA’s (European Space Agency) fifth and final Automated Transfer Vehicle (ATV) undocked from the International Space Station’s aft port of the Zvezda service module at 8:42 a.m. EST.

ATV-5 will move to a safe distance from the space station for its deorbit and destructive entry in the Earth’s atmosphere Sunday.

This is the last in a series of European resupply spacecraft that began servicing the space station in the spring of 2008. In all, the ATVs delivered approximately 34 tons of supplies to the complex while docked to the station of 776 days. ESA is applying its technology and knowledge from the cargo ship to develop the service module for NASA’s Orion spacecraft.
