The seven Expedition 69 crew members are turning their attention to a pair of spacewalks and a cargo mission after saying goodbye to their Axiom Mission-2 (Ax-2) guests on Tuesday. Meanwhile, a pair of experiments onboard the International Space Station on Wednesday looked at monitoring health and 3D printing.

The four astronauts and three cosmonauts that comprise Expedition 69 are resuming their standard mission activities today following the departure of four Ax-2 astronauts. Next up in June for the orbital residents are a pair of spacewalks to upgrade the station’s power generation system and a commercial resupply mission.

Mission managers will preview the upcoming power upgrade spacewalks during a news conference live on NASA TV at 12 p.m. EDT on Thursday. The first spacewalk will begin at 9:15 a.m. on June 9 with NASA Flight Engineers Stephen Bowen and Woody Hoburg. The duo will exit the Quest airlock in their Extravehicular Mobility Units (EMUs), or spacesuits, and install a new roll-out solar array on the orbital lab’s starboard-side truss segment. The second spacewalk will take place on June 15 with a duo going back out in EMUs and installing another roll-out solar array on the starboard truss.

Bowen and Hoburg started Wednesday morning reviewing their spacewalk activities and cleaning spacesuit cooling loops. The pair then joined Flight Engineers Frank Rubio of NASA and Sultan Alneyadi of UAE (United Arab Emirates) in the afternoon for spacewalk training. The quartet logged into a computer and practiced the Canadarm2 robotic arm maneuvers necessary to support the solar array installation work planned for next Friday.

Both roll-out solar arrays are packed inside the trunk of the SpaceX Dragon cargo craft that is counting down to liftoff at 12:35 p.m. on Saturday from NASA’s Kennedy Space Center. Dragon will arrive at the station for an automated docking to the Harmony module’s space-facing port at 5:36 a.m. on Monday. The new solar arrays will be extracted from Dragon’s trunk with the Canadarm2 two days before the first spacewalk begins and staged on a pallet attached to the starboard truss. Dragon is also carrying new experiments, food, supplies, and hardware to replenish the station crew.

Microgravity science is still continuing onboard the station while the crew gets ready for the upcoming cargo mission and spacewalks. Alneyadi put on the Bio-Monitor vest and headband at the end of the day testing their ability to monitor an astronaut’s health while minimally interfering with crew activities. Commander Sergey Prokopyev worked on a 3D printer to demonstrate printing tools and parts in space reducing the crew’s reliance on cargo missions for hardware.

Prokopyev also partnered with Roscosmos Flight Engineer Dmitri Petelin installing upgraded data cables in the Zvezda service module. Flight Engineer Andrey Fedyaev spent his day on ventilation and electronics maintenance.

Life science for the benefit of human beings living on and off the Earth once again filled the research schedule aboard the International Space Station for the Expedition 69 and Axiom Mission-2 (Ax-2) crew members.

Flight Engineers Frank Rubio of NASA and Sultan Alneyadi of UAE (United Arab Emirates) worked on a pair of space biology studies with Ax-2 Mission Specialists Ali Alqarni and Rayyanah Barnawi throughout Friday. Alneyadi partnered with Barnawi during the morning treating human cell samples inside the Kibo laboratory module’s Life Science Glovebox (LSG) for a study observing their inflammatory response to microgravity. Barnawi then spent the afternoon servicing stem cell samples in the LSG with Rubio for a study that seeks to improve regenerative cell therapies on Earth. Alqarni began the stem cell study during the morning inserting the samples into a fluorescence microscope for imaging inside the Destiny laboratory module.

At the end of the day, Alneyadi got together again with Barnawi and Alqarni for the Bio-Data investigation helping the private astronauts measure their blood pressure, blood oxygen, heart rate levels, and investigate changes in brain blood flow and function in microgravity. The human research study is assessing different tools that monitor brain and eye health and may offset the long-term effects of living in weightlessness.

Ax-2 Commander Peggy Whitson and Pilot John Shoffner also worked on different biomedical research studies exploring ways to improve life on Earth and in space. Whitson removed tumor cell samples from a research incubator and placed them in the fluorescence microscope for imaging to learn how cancers form and possibly develop ways to predict and treat cancer on Earth. Shoffner exercised while wearing a specialized skinsuit to demonstrate its ability to prevent space-caused and Earth-bound back problems.

NASA Flight Engineers Stephen Bowen and Woody Hoburg had their hands full on Friday reviewing spacewalk procedures and organizing cargo for return to Earth. The duo first took turns studying maneuvers on a computer for an upcoming spacewalk to install a roll-out solar array on the orbital outpost’s truss structure. Bowen and Hoburg then spent the afternoon together collecting and prepacking gear that will be stowed inside the SpaceX Dragon cargo vehicle after it arrives in June.

The space station’s three cosmonauts spent their day on cardiac research, cargo duties, and life support maintenance. Commander Sergey Prokopyev first attached sensors to himself measuring his heart activity for a long-running Roscosmos cardiac study. Afterward, he replaced components inside the Vozdukh carbon dioxide removal device then checked its performance. Flight Engineers Dmitri Petelin and Andrey Fedyaev partnered together in the morning updating station data files to account for Wednesday’s arrival of the ISS Progress 84 resupply ship. The duo then split up for the rest of the day working on orbital plumbing and ventilation systems.

The Expedition 69 and Axiom Mission-2 (Ax-2) crews worked throughout Thursday conducting a multitude of space research aboard the International Space Station. Meanwhile, the orbiting lab’s three cosmonauts started unpacking a new cargo ship and worked on the European robotic arm controller.

Science is moving full speed ahead aboard the orbital outpost as four Expedition 69 astronauts and four Ax-2 private astronauts focused their research activities on a variety of space biology studies on Thursday. The life science and human research studies may provide insights unattainable on Earth promoting healthier astronauts living in space and humans on the ground.

UAE (United Arab Emirates) astronaut Sultan Alneyadi assisted Ax-2 Mission Specialist Rayyanah Barnawi in the Kibo laboratory module as she treated samples for a study exploring the effects of microgravity on the inflammatory response of human cells. Afterward, Barnawi was joined by NASA Flight Engineer Frank Rubio as she serviced stem cell samples inside Kibo’s Life Science Glovebox to potentially improve regenerative cell therapies on Earth.

Ax-2 Pilot John Shoffner and Ax-2 Mission Specialist Ali Alqarni joined each other for eye and brain scans. The private astronauts took turns in the morning scanning each other’s eyes with the Ultrasound 2 device in the Columbus laboratory module. The pair then got back together in the Destiny laboratory module during the afternoon, each wearing a cap filled with sensors, for a scan of their brains’ oxygen levels using near-infrared light. The scans are part of a single Ax-2 study that may provide insights into the effects of weightlessness on cognition and vision.

NASA Flight Engineers Stephen Bowen and Woody Hoburg also participated in a pair of eye scans on Thursday. The duo’s first test saw them scanning each other’s eyes with the Ultrasound 2 in Columbus. Afterward, Hoburg examined Bowen’s eyes using standard medical imaging hardware in the Harmony module that can be found in an optometrist’s office on Earth. Doctors on the ground assisted the pair during both eye checks to understand how an astronaut’s eye shape and vision may change while living long-term in space.

Ax-2 Commander Peggy Whitson began her day swapping tumor cell samples inside a fluorescence microscope to help researchers understand how cancers form and possibly develop ways to predict and treat cancer on Earth. The former NASA astronaut would later spend the rest of the day supporting her Ax-2 crewmates.

Station Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin, both from Roscosmos, began Thursday disassembling the new ISS Progress 84 (84P) resupply ship’s docking mechanism following its arrival at 11:19 a.m. EDT on Wednesday. Petelin would go on and unpack priority cargo from inside the 84P. Prokopyev studied futuristic spacecraft and robotic piloting techniques then stowed trash and discarded gear inside the ISS Progress 83 cargo craft. Meanwhile, Flight Engineer Andrey Fedyaev worked throughout Thursday configuring data on the European robotic arm’s internal controller located inside the Nauka science module.
