Space Station

The Expedition 69 crew members continue preparing the International Space Station for the arrival four private astronauts early next week. Meanwhile, the orbital residents also stayed focused on their life science activities and lab maintenance tasks.

The SpaceX Falcon 9 rocket, with the Dragon Freedom crew ship attached, rolled out to its launch pad at the Kennedy Space Center in Florida on Thursday morning. It is scheduled to launch four Axiom Mission-2 (Ax-2) astronauts at 5:37 p.m. EDT on Sunday to the orbital outpost. Former NASA astronaut and Ax-2 Commander Peggy Whitson will lead first-time space flyers Pilot John Shoffner and Mission Specialists Ali Alqarni and Rayyanah Barnawi aboard Dragon during its space flight. Dragon will automatically approach and dock to the space-facing port on the Harmony module at 9:24 a.m. on Monday.

Two station flight engineers spent a portion of Thursday configuring station equipment to support the four Ax-2 crew members during their stay aboard orbital lab. NASA astronaut Stephen Bowen gathered and staged emergency hardware on midday Thursday to accommodate the additional astronauts and their Dragon vehicle. UAE (United Arab Emirates) astronaut Sultan Alneyadi relocated a station computer from the Kibo laboratory module to the Harmony module for Ax-2 crew use.

Bowen would go on and work the rest of the day inside the Destiny laboratory module servicing life support gear that cools station hardware and rejects heat using water loops. Alneyadi charged batteries, removed components, and practiced installing jetpacks on the Extravehicular Mobility Units, or spacesuits, in preparation for upcoming spacewalks.

NASA Flight Engineer Frank Rubio worked inside the Kibo lab installing protein crystal research hardware and a centrifuge supporting life science and physics research. NASA astronaut Woody Hoburg wrapped up the checkout and activation of the Treadmill 2 in the Tranquility module following its inspection and cleaning earlier in the week.

Commander Sergey Prokopyev joined Flight Engineer Dmitri Petelin after breakfast for ultrasound scans of their stomachs to understand microgravity’s effect on the digestion process. Roscosmos Flight Engineer Andrey Fedyaev attached sensors to himself recording his heart activity while pedaling on an exercise cycle for a fitness evaluation. Fedyaev that partnered with Prokopyev at the end of the day transferring cargo from the ISS Progress 83 resupply ship docked to the Zvezda service module’s aft port.

The Expedition 69 crew spent Wednesday servicing an array of science gear, maintaining orbital lab systems, and readying gear for the next private astronaut mission. The International Space Station crew members also joined each other at the end of the day and practiced responding to a variety of emergency scenarios.

NASA Flight Engineers Frank Rubio and Woody Hoburg worked during the morning on science hardware supporting different space biology experiments. Rubio uninstalled video components inside the Cell Biology Experiment Facility, a research incubator that generates artificial gravity. Hoburg deployed a computer on the Tranquility module’s life support rack before ground controllers loaded network security software into the device.

Rubio later joined UAE (United Arab Emirates) astronaut Sultan Alneyadi and returned the station’s Treadmill 2 to its normal configuration inside Tranquility. Alneyadi and Hoburg had worked the day before on the treadmill rotating it out of its stowage position to inspect and clean its electronic components.

NASA Flight Engineer Stephen Bowen swapped out pharmaceutical samples inside the Microgravity Science Glovebox for the Ring Sheared Drop experiment that seeks potential treatments for neuro-degenerative diseases. He also removed a vest and headband he was wearing that recorded his vital signs and prepared the medical data for review by doctors on the ground.

Bowen also prepared computer tablets that will be used during the upcoming Axiom Mission-2 (Ax-2). Bowen configured the devices to allow the Ax-2 crew to access ground resources and connect to the internet. Ax-2 will be commanded by former NASA astronaut Peggy Whitson who will lead first-time space flyers Pilot John Shoffner and Mission Specialists Ali Alqarni and Rayyanah Barnawi. The private quartet is scheduled to launch aboard the SpaceX Dragon spacecraft at 5:37 p.m. EDT on Sunday from NASA’s Kennedy Space Center and automatically dock to the orbiting lab at 9:24 a.m. on Monday.

Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin worked throughout Wednesday on life support maintenance before partnering together and testing ultrasound gear for a human research study. Flight Engineer Andrey Fedyaev spent his day inspecting surfaces inside the Roscosmos station modules.

At the end of the day, all seven crewmates joined each other for a regularly scheduled emergency training session. The orbital residents reviewed how they would coordinate their response to unlikely emergency events such as a fire, an ammonia leak, or a pressure leak. They familiarized themselves with escape routes, safety gear, and communication protocols with mission controllers.

Mission managers have given the go for the launch of the second private astronaut mission to the International Space Station on Sunday. The Expedition 69 crew is preparing to meet the new astronauts while also keeping up its human research, maintaining orbital lab systems, and stowing spacewalk tools.

Axiom Space, SpaceX, and NASA managers met on Monday and agreed to launch four Axiom Mission-2 (Ax-2) crew members to the space station at 5:37 p.m. EDT on Sunday. Veteran astronaut and commander Peggy Whitson will lead first-time space flyers Pilot John Shoffner and Mission Specialists Ali Alqarni and Rayyanah Barnawi aboard the SpaceX Dragon spacecraft and guide it to an automated docking at 9:24 a.m. on Monday. The private astronauts will enter the station through the Harmony module’s space-facing port and begin several days of research, outreach, and commercial activities before returning to Earth.

Four station flight engineers joined each other during Tuesday afternoon and reviewed the Ax -2 mission schedule. NASA astronauts Stephen Bowen, Frank Rubio, and Woody Hoburg, along with UAE (United Arab Emirates) astronaut Sultan Alneyadi familiarized themselves with the upcoming mission activities and reviewed how the crews will coordinate during docked operations.

In the meantime, the seven space station residents continued ongoing microgravity science and kept up the maintenance of the orbital outpost. Spacesuit work and cargo transfers also rounded out the day.

Bowen was back on human research Tuesday morning servicing samples in a centrifuge for a study exploring the immunity systems of astronauts. Rubio powered on the Astrobee free-flying robotic assistants then removed experiment hardware from inside the Kibo laboratory module’s airlock.

Hoburg and Alneyadi spent most of the day working on the Tranquility module’s treadmill. The duo rotated the exercise rack from its stowage position to gain access to its internal electronics components for inspection and cleaning. Alneyadi then spent a few moments testing the operations of the Astrobees for an upcoming student competition to control the robotic devices.

Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin continued cleaning up after last week’s spacewalk. The duo reconfigured the Poisk airlock and stowed the tools and hardware used during the five-hour and 14-minute excursion that saw the deployment of a radiator on the Nauka science module. Prokopyev also partnered with Roscosmos Flight Engineer Andrey Fedyaev unpacking cargo from the ISS Progress 83 cargo craft, while Petelin also explored how weightlessness affects the cardiovascular system.
