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.

During a four-hour and one-minute spacewalk on Wednesday, Commander Oleg Artemyev and Flight Engineer Denis Matveev installed a pair of cameras on the European robotic arm (ERA) and removed parts attached to the arm’s end effector. Today, the cosmonauts powered down their Orlan spacesuits and removed suit components. Flight Engineer Sergey Korsakov reconfigured the Poisk module back to normal operations.

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.

Dragon Cargo Craft Undocking Postponed to Friday

The SpaceX Dragon resupply ship carrying over 5,800 pounds of cargo approaches the space station above the south Atlantic Ocean on July 16, 2022.

The Expedition 67 crew split up today with the astronauts studying wound healing techniques and the cosmonauts preparing for a spacewalk to prepare a new robotic arm for operations. A U.S. space freighter has also been given the “go” to return to Earth at the end of the week.

Researchers are exploring tissue regeneration in the International Space Station’s microgravity environment to develop new ways to heal wounds benefitting humans living in space and on Earth. The astronauts took turns throughout Tuesday investigating how spaceflight conditions, such as weightlessness and radiation, affect genetic expressions that occur during the healing process.

NASA Flight Engineers Kjell Lindgren and Jessica Watkins began the day’s first set of experiment operations taking place in the Kibo laboratory module’s Life Science Glovebox. Astronauts Bob Hines of NASA and Samantha Cristoforetti of ESA (European Space Agency) took over in the afternoon continuing the biology study that utilizes basic surgical techniques.

The skin healing experiment will wrap up on Wednesday when the astronauts load the research samples and other cargo inside the SpaceX Dragon resupply ship for analysis by scientists and engineers on Earth. Mission managers have approved Dragon’s departure for 11:05 a.m. EDT on Thursday when it will undock from the Harmony module’s forward port. The commercial cargo craft will parachute to a splashdown off the coast of Florida on Friday with over 4,000 pounds of cargo and research for retrieval.

Meanwhile, two cosmonauts are ready for their spacewalk to continue outfitting the European robotic arm (ERA) for payload operations on the orbiting lab’s Russian segment. Roscosmos spacewalkers Oleg Artemyev and Denis Matveev are finalizing their task list reviews and Orlan spacesuit checks today with assistance from Flight Engineer Sergey Korsakov.

Artemyev and Matveev are scheduled to exit the Poisk module’s airlock at 9:20 a.m. on Wednesday and spend about six-and-a-half hours servicing the ERA. The duo will install cameras on the ERA, move its external control panel, remove the robotic arm’s launch restraints, and test the arm’s grasping mechanism. Korsakov will monitor his cosmonaut crewmates during their excursion and help them in and out of their spacesuits. NASA TV, on the agency’s app and website, will begin its live spacewalk coverage at 9 a.m.

Mission managers have given the “go” for the seventh spacewalk of the year scheduled to take place in the middle of the week. A U.S. cargo craft is also nearing the end of its mission with its undocking and return to Earth planned for the end of the week.

Two cosmonauts are gearing up for a six-and-a-half-hour spacewalk to continue setting up the European robotic arm (ERA) for operations on the outside of the International Space Station’s Russian segment. Commander Oleg Artemyev and Flight Engineer Denis Matveev will exit the Poisk module’s airlock at 9:20 a.m. EDT on Wednesday in their Russian Orlan spacesuits. The pair will install cameras on the ERA, move its external control panel, remove the robotic arm’s launch restraints, and test the arm’s grasping mechanism. NASA TV, on the agency’s app and website, will begin its live spacewalk coverage at 9 a.m.

Roscosmos Flight Engineer Sergey Korsakov is assisting his fellow cosmonauts with the spacewalk preparations while also maintaining orbital lab systems and conducting space research. Today, he worked on ventilation systems inside the Nauka module then explored effective exercise techniques to maintain physical fitness in microgravity.

Meanwhile, the SpaceX Dragon resupply ship is nearing the end of its monthlong stay on the Harmony module’s forward port. Expedition 67 Flight Engineers Jessica Watkins of NASA and Samantha Cristoforetti of ESA (European Space Agency) spent Monday afternoon packing Dragon with some of the more than 4,000 pounds of station gear and completed science experiments it will return to Earth. Dragon will undock at 11:05 a.m. on Thursday and parachute to a splashdown off the coast of Florida the following day for retrieval. Live undocking coverage on NASA TV begins at 10:45 a.m. on Thursday.

NASA Flight Engineers Kjell Lindgren and Bob Hines spent Monday focusing on life science to improve human health on and off the Earth. Lindgren set up tissue stem cell samples inside the Life Science Glovebox (LSG) to explore how weightlessness affects immunological aging possibly promoting therapies to protect astronauts and Earthlings. Afterward, Hines cleaned up the LSG in the Kibo laboratory module to prepare for experiment operations that will use the microgravity environment to develop new wound treatment techniques.

Skin healing processes and spacewalk preparations filled the work schedule aboard the International Space Station on Friday. The Expedition 67 crew members are also readying a U.S. space freighter for its return to Earth next week.

Four astronauts aboard the orbiting lab practiced surgical techniques to heal wounds in microgravity on Friday in the Kibo laboratory module. The quartet split up in groups of two with NASA astronaut Bob Hines joining ESA (European Space Agency) Flight Engineer Samantha Cristoforetti for the first practice session during the morning. In the afternoon, NASA Flight Engineers Kjell Lindgren and Jessica Watkins began their session studying how to take biopsies and suture wounds inside the Life Science Glovebox.

During the middle of the day, the foursome had time set aside time for gathering frozen research samples inside science freezers and preparing them for departure back to Earth inside the SpaceX Dragon resupply ship. Dragon is due to leave the station on Aug. 18 loaded with over 4,000 pounds of station supplies and science experiments after 33 days docked to the Harmony module’s forward port. The commercial cargo craft will parachute to a splashdown off the coast of Florida the next day for retrieval by NASA and SpaceX personnel.

Watkins and Cristoforetti started the day collecting blood samples for spinning in a centrifuge then stowing them in a science freezer. Lindgren  evaluated the effectiveness of the Butterfly IQ Ultrasound device that uses mobile-computing technology to promote crew autonomy. Hines wrapped up his day with light orbital plumbing tasks and spacewalk tether inspections.

Two cosmonauts are gearing up for a spacewalk on Aug. 17 to continue configuring the European robotic arm (ERA) for operations on the station’s Russian segment. Commander Oleg Artemyev and Flight Engineer Denis Matveev tried on their Orlan spacesuits, tested communications gear, checked for leaks, and practiced maneuvers planned for next week’s six-and-half-hour excursion. Flight Engineer Sergey Korsakov assisted the duo during the spacewalking dry run and will be on duty monitoring his two crewmates when they exit the Poisk module’s airlock next week for the ongoing ERA work.

Healing wounds in space and growing crops in low-Earth orbit and beyond were the main research topics aboard the International Space Station on Thursday. Meanwhile, the Expedition 67 crew is also packing a U.S. cargo craft and preparing for a Russian spacewalk next week.

Two-time space station resident Kjell Lindgren of NASA set up hardware during the morning inside the Life Science Glovebox for a biology experiment studying how skin heals in weightlessness. He was joined in the afternoon by fellow astronauts Bob Hines and Jessica Watkins, both from NASA, and Samantha Cristoforetti of ESA (European Space Agency) for an experiment procedures review and a conference with the payload developer on the ground. Observations may provide insights improving wound healing techniques for astronauts and Earthlings.

Hines and Watkins began their day drawing their blood samples, spinning them in a centrifuge, then stowing them in a science freezer for later analysis. Hines then inspected seeds and recirculated fluids for the XROOTS botany study growing mizuna greens and radishes to explore agricultural techniques in space. Watkins later worked on orbital plumbing duties inside the Unity module.

Cristoforetti began her day servicing research gear as she downloaded Acoustic Monitor data to a laptop computer then swapped components on a fluorescence imaging microscope. At the end of the day, she continued stowing cargo inside the SpaceX Dragon resupply ship readying it for its return to Earth later this month.

Cosmonauts Oleg Artemyev and Denis Matveev are gearing up for another spacewalk on Aug. 17 to prepare the European robotic arm (ERA) for operations on the station’s Russian segment. The duo has been readying their Russian Orlan spacesuits, spacewalking tools, and the Poisk module’s airlock for next week’s planned six-and-half-hour spacewalk. Flight Engineer Sergey Korsakov, who will assist the spacewalkers next week, is also configuring the ERA for the upcoming excursion, which would be this year’s seventh spacewalk.
