Today is homecoming day for International Space Station Commander Barry “Butch” Wilmore of NASA and Flight Engineers Alexander Samokutyaev and Elena Serova of the Russian Federal Space Agency (Roscosmos) as they prepare for landing in their Soyuz TMA-14M spacecraft at 10:07 p.m. EDT this evening, southeast of Dzhezkazgan, Kazakhstan.
At this time, there are no concerns or issues being worked.
Wilmore handed over command of the orbiting complex to fellow NASA astronaut Terry Virts in a ceremony on Tuesday, March 10. When the Soyuz undocks, Expedition 43 formally will begin.
NASA Television coverage times for Soyuz activities are listed below. These activities also will stream online at https://www.nasa.gov/ntv.
Here is a timeline of the Expedition 42 undocking and landing.
Expedition 42 Commander Barry Wilmore handed over control of the International Space Station to NASA astronaut Terry Virts in a Change of Command Ceremony today. Virts will lead Expedition 43 when Wilmore and Soyuz Commander Alexander Samokutyaev and Flight Engineer Elena Serova undock Wednesday at 6:44 p.m. EDT in their Soyuz TMA-14M spacecraft.
Back on Earth, a new Expedition 43 trio is relaxing as they count down to their March 27 launch. Riding with Soyuz TMA-16M Commander Gennady Padalka are One-Year crew members Scott Kelly and Mikhail Kornienko who will live in space until March 2016. Padalka will stay in space till September.
Meanwhile inside the station, Virts continues installing cables so future commercial crew vehicles can communicate with a pair of International Docking Adapters to be installed later this year. He and Flight Engineers Anton Shkaplerov and Samantha Cristoforetti also reviewed their emergency roles and responsibilities and practiced communication and coordination.
Expedition 42 crew members Barry Wilmore, Alexander Samokutyaev and Elena Serova are two days away from ending their stay aboard the International Space Station. The trio is packing gear and cleaning crew quarters as they prepare to undock in their Soyuz TMA-14M spacecraft Wednesday at 6:44 p.m. EDT and land in Kazakhstan at 10:07 p.m.
Wilmore, the commander of Expedition 42, will handover control of the orbital laboratory Tuesday to NASA astronaut Terry Virts who will command Expedition 43. The Change of Command Ceremony will take place live on NASA TV at 10:25 a.m.
Meanwhile, advanced microgravity science and laboratory maintenance is ongoing aboard the space station. Among the experiments, the crew studied body size and shape in space for suit sizing and looked at airway inflammation in astronauts. Ethernet cables were also installed in the Harmony module that will enable future commercial crew vehicles to communicate with a pair of upcoming International Docking Adapters.
Astronauts Terry Virts and Samantha Cristoforetti were in the U.S. Quest airlock conducting airflow monitor tests, measurements and calibrations. The tests were part of the Airway Monitoring experiment that is looking for possible indicators of airway inflammation in astronauts during spaceflight.
Their crewmate Anton Shkaplerov worked in the Zarya cargo module sampling equipment surfaces for microbial analysis. He also photographed the condition of the surfaces inside the Zarya module.
Their homebound crewmates Expedition 42 Commander Barry Wilmore, Soyuz TMA-14M Commander Alexander Samokutyaev and Flight Engineer Elena Serova practiced a Soyuz descent drill ahead of their March 11 departure and landing in Kazakhstan.
The next trio of space station to crewmates to launch to the International Space Station conducted a news conference Friday then laid flowers at the Kremlin Wall at the Red Square in Moscow. One Year crew members Scott Kelly and Mikhail Kornienko along with Soyuz TMA-16M Commander Gennady Padalka are set to launch March 27 to join their Expedition 43 crewmates.
The Expedition 42 crew completed the deployment of numerous nanosatellites while also preparing for the departure of a Soyuz crew. The six-member crew also worked on advanced microgravity research and the upkeep of their orbital laboratory and home.
The final pair of Cubesats was deployed overnight completing the launch of a total of 16 nanosatellites from outside the Kibo lab module. The Cubesats were launched from the International Space Station to perform a variety of research.
Commander Barry Wilmore and his Soyuz crewmates Alexander Samokutyaev and Elena Serova are counting down to their departure March 11. Staying behind will be new Expedition 43 Commander Terry Virts and Flight Engineers Samantha Cristoforetti and Anton Shkaplerov.
They will be waiting for new Expedition 43 crew mates Scott Kelly, Mikhail Kornienko and Gennady Padalka who are scheduled to lift off March 27. Kelly and Kornienko are in Star City, Russia, completing final mission preparations and will stay aboard the station until March 2016.
Soyuz TMA-14M Commander Alexander Samokutyaev and Flight Engineer Elena Serova are counting to their departure March 11 with Expedition 42 Commander Barry Wilmore. The two cosmonauts trained on Soyuz descent procedures and checked out emergency communications gear. Wilmore also prepared for his departure and began packing gear for the return home.
Meanwhile, One-Year crew members NASA astronaut Scott Kelly and cosmonaut Mikhail Kornienko are in Star City, Russia, getting ready for final qualification exams in the Soyuz trainer. They are at the Gagarin Cosmonaut Training Center preparing for their launch aboard a Soyuz TMA-16M spacecraft March 27 from the Baikonur Cosmodrome. The veteran space duo will take a six-hour, four-orbit ride to the International Space Station where they will live and work until March 2016.
As a pair of astronauts cleans up their spacesuits after completing a set of spacewalks, more nanosatellites were deployed from Japan’s Kibo lab module. The International Space Station also raised its orbit Tuesday morning to set the stage for the upcoming crew departure.
Astronauts Barry WiImore and Terry Virts scrubbed the cooling loops inside the spacesuits after their third and final spacewalk on Sunday. They also sampled the water from the loops and talked about their experiences with spacewalk experts on the ground.
Wilmore is also getting ready to return home March 11 with Soyuz crewmates Alexander Samokutyaev and Elena Serova. Samokutyaev and Serova spent Tuesday getting their Soyuz spacecraft ready for next week’s undocking and packing gear for the return home.
NASA astronauts Terry Virts and Barry Wilmore ended their spacewalk at 12:30 p.m. EST with the repressurization of the Quest airlock. Virts and Wilmore completed installing 400 feet of cable and several antennas associated with the Common Communications for Visiting Vehicles system known as C2V2. Boeing’s Crew Transportation System (CST)-100 and the SpaceX Crew Dragon will use the system in the coming years to rendezvous with the orbital laboratory and deliver crews to the space station. They completed one additional task to retrieve a bag to cover equipment on the outside of the station.
The 5-hour, 38-minute spacewalk was the third for Virts and the fourth for Wilmore. Virts has now spent 19 hours and 2 minutes outside during his three spacewalks. Wilmore now has spent 25 hours and 36 minutes in the void of space during his four excursions.
Crews have now spent a total of 1,171 hours and 29 minutes conducting space station assembly and maintenance during 187 spacewalks.
Approximately three hours into today’s spacewalk, NASA astronauts Terry Virts and Barry Wilmore have installed cables for the Common Communications for Visiting Vehicles (C2V2) system and completed tasks along the port side of the space station’s truss. To complete the system’s installation, they will route the remaining cables along the starboard side.
They are about an hour ahead of the timeline. Both astronauts continue to report that their spacesuits are functioning perfectly.
