Artemyev and Matveev will exit out of the Poisk module about 9:20 a.m. EDT to begin the approximately six-and-a-half-hour excursion. Artemyev will wear a Russian Orlan spacesuit with red stripes, while Matveev will wear a Russian Orlan suit with blue stripes. This will be the eighth spacewalk for Artemyev and the fourth for Matveev. It will be the eighth spacewalk at the station in 2022 and the 253rd spacewalk for space station assembly, maintenance, and upgrades.
Today’s spacewalk will complete the unfinished tasks of the previous spacewalk on Aug. 17, which was cut short after Atemyev’s Orlan spacesuit showed abnormal battery readings about 2 hours and 17 minutes into the extravehicular activity. Before the spacewalk ended, Artemyev and Matveev completed the installation of a pair of cameras on the arm and removed parts attached to the arm’s end effector.
The European robotic arm will be used to move payloads and equipment outside the Russian segment of the station, joining the Canadian-built Canadarm2 robotic arm and the Japanese arm already supporting station maintenance, operations, and research.
Two cosmonauts are finalizing preparations for a spacewalk to configure the European robotic arm (ERA) for payload operations on the outside of the International Space Station. The rest of the Expedition 67 crew is continuing to research how to heal wounds in the microgravity environment.
Roscosmos Commander Oleg Artemyev and Flight Engineer Denis Matveev have been given the go to exit the space station’s Poisk airlock on Friday at 9:20 a.m. EDT beginning a spacewalk to continue outfitting Europe’s robotic arm. The duo was joined today by Flight Engineer Sergey Korsakov for a final procedures review and last minute Orlan spacesuit checks ahead of the planned six-hour spacewalk.
The spacewalkers will complete the tasks left unfinished during the previous spacewalk that took place on Aug. 17. The tasks Artemyev and Matveev are scheduled to complete include relocating the ERA’s external control panel and testing the arm’s ability to grasp payloads. Korsakov will help the two cosmonauts in and out of their spacesuits, monitor the spacewalking activities, and maneuver the ERA on Friday.
The orbiting lab’s four other astronauts spent the entire day in the Kibo laboratory module learning how to heal wounds in weightlessness. A key characteristic of living and working in space is the accelerated aging of skin that astronauts experience. Researchers are studying those molecular processes and how they affect the healing process potentially advancing wound treatments both in space and on Earth.
Using Kibo’s Life Science Glovebox, NASA astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins, along with Samantha Cristoforetti of ESA (European Space Agency) practiced surgical techniques including biopsies, suture splints, and wound dressing. The quartet will continue the biomedical research on Friday helping NASA and its international partners keep astronauts safe and healthy on long-term space missions while improving health conditions on Earth.
The way skin heals and how plants grow in space are critical research topics aboard the International Space Station. NASA and its international partners glean insights from the scientific data to boost human health and plan successful crewed missions to the Moon, Mars, and beyond.
Hines then wrapped up his workday in ESA’s Columbus laboratory module supporting the XROOTS space botany investigation. The NASA astronaut mixed a nutrient solution and recirculated fluids to nourish radishes and mizuna greens growing inside Columbus’ Veggie botany research system. The experiment uses hydroponic and aeroponic methods as a way to promote space agriculture and sustain crews on long-term space missions.
Cristoforetti started her day charging spacesuit video camera batteries, servicing the U.S. oxygen generation system, and documenting her meals for a nutrition study. Following her mid-afternoon support for the skin study, Cristoforetti finished her day performing light plumbing duties and checking portable fire extinguisher components.
Cosmonauts Oleg Artemyev and Denis Matveev began their day studying the tasks and maneuvers they will use to configure the European robotic arm on an upcoming spacewalk. The pair from Roscosmos also checked Orlan spacesuit components and systems. Flight Engineer Sergey Korsakov spent Wednesday maintaining laptop computers and electronics systems throughout the orbiting lab’s Russian segment.
Vein scans and human research samples comprised the majority of the research schedule for the Expedition 67 crew members on Tuesday. Spacesuit work is also ongoing aboard the International Space Station as the cosmonauts prepare for a spacewalk.
Three astronauts took turns on Tuesday morning using the Ultrasound 2 device to scan each other’s neck, shoulder, and leg veins. NASA Flight Engineers Kjell Lindgren, Bob Hines, and Jessica Watkins started the day inside the Columbus laboratory module with researchers on the ground remotely guiding the biomedical study. The ultrasound scans produce an echo that bounces off human tissue converting it to a video signal that is downlinked to Earth in real-time for analysis. Scientists view the imagery to observe how microgravity affects crew health.
The crew members also regularly collect their own blood, saliva, and urine samples, stowing the specimens in science freezers for later analysis. Shortly after Lindgren woke up on Tuesday, he spun his blood samples in a centrifuge for the Phospho-aging study to understand space-caused accelerated bone loss and muscle atrophy. ESA (European Space Agency) Flight Engineer Samantha Cristoforetti collected her blood and urine samples during the afternoon for future examination. Earlier, she documented her meals for a nutrition study then swapped material samples inside the Electrostatic Levitation Furnace, a high-temperature research facility.
Cristoforetti and Watkins also spent time inside the U.S. Quest airlock servicing a U.S. spacesuit. The duo split their day on a variety of suit activities including swapping components and cleaning cooling loops. Hines spent his afternoon charging computer tablets and downloading security updates for the devices.
Commander Oleg Artemyev and Flight Engineer Denis Matveev spent the day activating and inspecting a pair of Orlan spacesuits, testing their communication systems, and performing leak checks. The two cosmonauts have been busy this week preparing for an upcoming spacewalk to prepare the European robotic arm for payload operations on the station’s Russian segment. Flight Engineer Sergey Korsakov worked throughout Tuesday maintaining electronics systems and life support hardware inside the orbiting lab’s Russian modules.
Space biology kicked off the week for the Expedition 67 crew on Monday to help NASA and its international partners support astronauts on long spaceflight missions. Two cosmonauts are also preparing for a spacewalk to continue outfitting the International Space Station’s third robotic arm.
Lindgren downloaded the muscle data captured from the Myotones device to a laptop computer connected to Columbus’ European Physiology Module, a research rack that supports neuroscientific, cardiovascular, and physiological studies. Afterward, the two-time station resident collected and stowed urine samples in a science freezer for later analysis.
Hines then went over to the Kibo laboratory module to continue studying how wounds heal in space. He joined Flight Engineers Jessica Watkins of NASA and Samantha Cristoforetti of ESA (European Space Agency) and practiced surgical techniques such as biopsies, suture splints, and wound dressing, inside Kibo’s Life Science Glovebox. Researchers are exploring the molecular processes behind space-caused skin aging that may impact the way wounds heal and possibly improve skin healing treatments for both astronauts and Earthlings.
Cosmonauts Oleg Artemyev and Denis Matveev continued setting up their tools and Orlan spacesuits today ahead of another planned spacewalk to configure the European robotic arm (ERA) for payload operations on the station’s Russian segment. Roscosmos Flight Engineer Sergey Korsakov spent his morning on computer maintenance inside the Nauka multipurpose laboratory module before switching to orbital plumbing duties during the afternoon.
International Space Station studies about wound healing and cardiology kicked off the week for the Expedition 67 crew following last week’s departure of a U.S. resupply ship. A variety of other space research, spacesuit cleaning, and maintenance rounded out the day for the seven orbital residents.
Lindgren then installed an AstroPi science computer in the Harmony module where Cristoforetti would adjust its camera lens allowing European students to take night time photography of the Earth below. Watkins recorded video of the AstroPi activities and downlinked it for viewing by the participating students on Earth. Hines checked fluids and plants growing for the XROOTS botany study that uses hydroponics and aeroponics techniques to promote space agriculture.
The SpaceX Dragon resupply ship completed its cargo mission after 34 days attached to the space station on Friday. It undocked from the Harmony module’s forward port at 11:05 a.m. EDT and parachuted to a splashdown off the coast of Cape Canaveral, Florida, on Saturday at 2:53 p.m. Shortly afterward, support personnel retrieved the commercial cargo craft, packed with scientific cargo and station gear, floating in the Atlantic.
Cosmonauts Oleg Artemyev and Denis Matveev continued stowing spacewalking gear today after last week’s spacewalk to outfit the European robotic arm for payload operations on the station’s Russian segment. The duo also researched cardiology onboard the station today exploring how weightlessness affects blood circulation. Roscosmos Flight Engineer Sergey Korsakov also participated in the heart research before he and Artemyev studied how to pilot spacecraft and maneuver robots on future planetary missions.
SpaceX’s uncrewed Dragon cargo spacecraft splashed down at 2:53 p.m. EDT Saturday, Aug. 20, north of Cape Canaveral off the Florida coast, marking the return of the company’s 25th contracted cargo resupply mission to the International Space Station for NASA. The spacecraft carried more than 4,000 pounds of valuable scientific experiments and other cargo back to Earth.
Space’s impact on materials: The Materials International Space Station Experiment-15-NASA (MISSE-15-NASA) experiment tests, qualifies, and quantifies the impact of the low-Earth orbit environment on new materials and components, such as spacecraft materials and wearable radiation protection. Successful experiment results could have applications both in the harsh environments of space and on Earth.
Spacesuit cooling: Spacesuit Evaporation Rejection Flight Experiment (SERFE) demonstrates a new technology using water evaporation to remove heat from spacesuits and maintain appropriate temperatures for crew members and equipment during spacewalks. The investigation determines whether microgravity affects performance and evaluates the technology’s effect on contamination and corrosion of spacesuit material.
Cell signaling in microgravity: The ESA (European Space Agency) sponsored investigation Bioprint FirstAid Handheld Bioprinter (Bioprint FirstAid) enables the rapid use of formerly prepared bio-inks, containing the patient’s own cells, to form a band-aid patch in the case of injury.
The Expedition 67 crew will wait an extra day before seeing a U.S. space freighter depart the International Space Station. In the meantime, the cosmonauts are cleaning up following a shorter-than-planned spacewalk after a power issue on a Russian Orlan spacesuit.
Mission managers representing NASA and SpaceX waved off Thursday’s undocking of the Dragon cargo craft due to adverse weather conditions at the splashdown site off the coast of Florida. Dragon is now due to leave the Harmony module’s forward port at 11:05 a.m. EDT on Friday.
Four of the station’s astronauts including Kjell Lindgren, Bob Hines, and Jessica Watkins, all from NASA, with Samantha Cristoforetti of ESA (European Space Agency), will finish packing Dragon with critical research samples early Friday morning before closing the commercial resupply ship’s hatch. Dragon is scheduled to parachute back to Earth on Saturday loaded with over 4,000 pounds of cargo including completed scientific experiments for analysis. NASA TV, on the agency’s app and website, begins its live undocking coverage at 10:45 a.m. on Friday.
Just over two hours after Thursday’s spacewalk began, Artemyev informed Russian mission controllers his spacesuit was experiencing abnormal battery readings. Mission controllers directed Artemyev to return to the Poisk’s airlock and connect his spacesuit to the station’s power supply. Matveev continued his tasks before cleaning up and heading back to Poisk after managers called off the robotic maintenance excursion. Korsakov maneuvered the ERA to a safe post-spacewalk configuration while the cosmonaut spacewalkers were never in any danger.
