The Expedition 46 crew continued studying how living off the Earth affects exercise, the biological clock and fire today. The orbiting space residents also worked on a spacesuit and other lab maintenance tasks.
NASA astronaut Tim Kopra scanned his legs mid-morning with an ultrasound for the Sprint study exploring exercise techniques for crews working in space for long periods. Kopra then moved on to fire research observing how different materials burn in space potentially improving fire safety on Earth and in space.
Kelly then joined British astronaut Tim Peake for ongoing gear replacement work inside a U.S. spacesuit for the rest of the day. Peake ended his shift attaching sensors to himself so doctors can monitor how a crew member adapts to 16 sunrises and sunsets a day while in low-Earth orbit.
The three cosmonauts worked on their share of station science and upkeep today. Sergey Volkov looked at the human digestive system while Yuri Malenchenko explored interactive ways to train crews on orbit. Mikhail Kornienko changed a lens on camera that students can control to photograph Earth features.
The Expedition 46 crew members participated in immunology research today helping scientists learn to keep astronauts healthy on longer and farther space missions. The crew also continued more vision checks and explored heart health.
Commander Scott Kelly, British astronaut Time Peake and cosmonaut Mikhail Kornienko each participated in a different experiment looking at the immune system of space residents.
Kelly collected body samples looking for microbes that could potentially cause infections or allergies and stowed them in a science freezer for analysis. Peake took a saliva sample for an experiment that is researching biomarkers for immune dysfunction in space. Kornienko explored how radiation and other unique factors of living in space could affect a crew member’s immune system.
NASA astronaut Tim Kopra also joined Kelly and Kornienko for eye exams for an experiment studying vision impairment reported by some International Space Station astronauts. Kopra and Peake also partnered up for ultrasound scans of their arteries with guidance from doctors on the ground. The ongoing Cardio Ox study looks at an astronaut’s carotid and brachial arteries before, during and after a space mission.
The Expedition 46 crew members kicked off their work week today with a series of physics experiments and life science studies. The crew also worked on U.S. and Russian spacesuits and continued packing trash inside the Orbital ATK resupply ship.
British astronaut Tim Peake wrapped up maintenance work on the Electrostatic Levitation Furnace which will study the thermophysical properties of various materials. NASA astronaut Tim Kopra tested the flammability of different textiles inside the Microgravity Science Glovebox for the BASS-M experiment.
Peake also explored crew immunology to potentially improve astronaut health and life on Earth. Kopra continued taking out the trash today loading the Cygnus spacecraft before its release on Feb. 19 for disposal over the Pacific Ocean.
Peake then joined Commander Scott Kelly in the Quest airlock to get a U.S. spacesuit ready for gear replacement work on Wednesday. Kelly also partnered up with cosmonaut Mikhail Kornienko for vision tests and blood pressure checks for the Ocular Health study.
Cosmonaut Yuri Malenchenko is recharging Russian Orlan spacesuit batteries after completing a spacewalk last week. His fellow cosmonaut Sergey Volkov also helped stow spacewalk tools.
The Expedition 46 crew members are wrapping up their work week on different types of research including botany, bone loss and pilot testing. The crew also checked for pressure leaks, worked on life support gear and continued cleaning up after a spacewalk.
Plants are being grown on the International Space Station so future crews can learn to become self-sustainable as they go farther out in space. Commander Scott Kelly took photos of the botany work today as part of the Veggie experiment.
The commander started his day in Japan’s Kibo lab module with British astronaut Tim Peake stowing a Cyclops satellite deployer and checking for leaks in the airlock. Kelly also joined Flight Engineer Tim Kopra cleaning up after installing the refurbished Carbon Dioxide Removal Assembly the day before.
Cosmonaut Mikhail Kornienko participated in a couple of experiments today looking at bone loss and pilot performance in space. He also checked for pressure leaks before the Progress 61 supply ship undocks March 29. His fellow cosmonauts Sergey Volkov and Yuri Malenchenko are still stowing tools and gear after Wednesday’s spacewalk.
Flight Engineers Yuri Malenchenko and Sergey Volkov completed the third spacewalk of Expedition 46 after installing hardware and science gear and conducting experiments. Today the duo are cleaning and recharging their Orlan spacesuits and stowing their tools.
Commander Scott Kelly and NASA astronaut Tim Kopra partnered together to swap parts inside the Carbon Dioxide Removal Assembly (CDRA). Kelly then packed trash inside the Orbital ATK Cygnus cargo craft due to leave the International Space Station on Feb. 19. Kopra later wrapped up the CDRA maintenance work.
Yuri Malenchenko and Sergey Volkov of Roscosmos began a planned 5.5-hour spacewalk from the Pirs Docking Compartment of the International Space Station at 7:55 a.m. EST.
Both spacewalkers are wearing Russian Orlan spacesuits with blue stripes. Malenchenko is designated as extravehicular crew member 1 (EV1). Volkov is designated extravehicular crew member 2 (EV2).
Prior to the start of today’s spacewalk, Malenchenko has spent 30 hours and five minutes outside the space station in support of space station assembly and maintenance. Volkov has previously accumulated 18 hours and 35 minutes.
Among their tasks today, the pair is scheduled to retrieve the EXPOSE-R Experiment, a collection of biological and biochemical samples placed in the harsh environment of space. The EXPOSE program is part of ESA’s (European Space Agency) research into astrobiology, or the study of the origin, evolution and distribution of life in the universe.
NASA Television is broadcasting the spacewalk. Watch live:
Two cosmonauts are getting ready for a spacewalk to install hardware and science experiments outside the International Space Station’s Russian segment. Meanwhile, the other four crew members are working on research hardware, water testing and trash stowage.
Veteran flight engineers and spacewalkers Yuri Malenchenko and Sergey Volkov are finalizing their reviews and preparations for the second Expedition 46 spacewalk in less than a month. NASA Television will provide live coverage of the Russian spacewalk set to begin tomorrow at 8:10 a.m. EST. They are scheduled to work outside in their Russian Orlan spacesuits for about 5 hours and 30 minutes on scheduled maintenance tasks.
Commander Scott Kelly set up a portable 3D printer today inside the Destiny laboratory module. The test fabrications on the device may precede the installation of a full-sized 3D printer in the future. Kelly also replaced fuel gear inside the Combustion Integrated Rack.
European astronaut Tim Peake collected and tested samples from water dispensers in the U.S. and Russian segments of the orbital lab. The samples will also be returned to Earth inside a Soyuz spacecraft for further analysis. NASA astronaut Tim Kopra continued stowing trash inside the Orbital ATK cargo craft while also checking the status of pistol grip tools used during spacewalks.
A pair of cosmonauts is getting ready for the 193rd International Space Station spacewalk beginning Wednesday at 8:10 a.m. EST. The other four Expedition 46 crew members worked on science, cargo transfers and maintenance today.

NASA TV will cover the spacewalk activities Wednesday starting at 7:30 a.m. The duo will install hardware and science experiments and photograph the external condition of the space station.
NASA astronaut Tim Kopra was back at work studying how materials burn in microgravity potentially improving fire safety on Earth and in space. British astronaut Tim Peake retracted a small satellite deployer back in the Kibo lab module and performed some maintenance work on the BioLab incubator.
Commander Scott Kelly packed trash and discarded gear inside the Orbital ATK Cygnus cargo craft scheduled to depart Feb. 19. Cosmonaut Mikhail Kornienko performed a series of interactive tasks on a tablet for the Fine Motor Skills investigation. Kelly and Peake also participated in the study that observes how astronauts work on touch-based, sensitive and detailed tasks on long duration space missions.
