Following Science, Spacewalk Cleanup a Planned Cygnus Boost Approaches

The Expedition 69 crew is continuing to unpack a U.S. cargo craft before it fires engines to reboost the International Space Station on Friday. The orbital residents are also continuing their science and maintenance activities while cleaning up the day after a spacewalk.

NASA astronauts Frank Rubio and Stephen Bowen continued unpacking some of the several tons of science and supplies still packed inside the Cygnus space freighter on Thursday. Cygnus will also fire it engines on Friday reboosting the orbital outpost. This will raise the station to the correct altitude for the upcoming arrival of a Roscosmos cargo craft in two weeks. The station will also be in the proper phasing for a Soyuz crew swap mission planned in mid- to late September.

Rubio also opened up the Combustion Integrated Rack to troubleshoot the computer electronics inside. Bowen monitored his blood pressure throughout the day and swapped samples in the Microgravity Science Glovebox for a space manufacturing study.

NASA Flight Engineer Woody Hoburg spent his day on inflight maintenance as he replaced charcoal filters in the Harmony module and loaded new software on a tablet computer. UAE (United Arab Emirates) astronaut Sultan Alneyadi organized food bags, helped Rubio unload the Cygnus cargo craft, then finally replaced window scratch panes in the cupola.

Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin are cleaning their Orlan spacesuits and stowing spacewalking gear following Wednesday’s spacewalk. The duo spent six hours and 35 minutes in the vacuum of space installing orbital debris shields and relocating a portable workstation on the Roscosmos segment of the space station.

Flight Engineer Andrey Fedyaev is returning the European robotic arm (ERA) to its stowage configuration on the Nauka science module.  Fedyaev commanded the ERA during Wednesday’s spacewalk moving the workstation from the Rassvet module to Nauka and testing its ability to maneuver a spacewalker with Prokopyev attached for the first time.

The Roscosmos trio got a late start on Thursday after sleeping in following a good night’s rest. During their cleanup activities, Prokopyev and Petelin also called down to mission controllers to discuss the previous day’s spacewalk activities.

Cosmonauts Finish Spacewalk Installing Shields and Relocating Hardware

Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin concluded their spacewalk outside the International Space Station at 5:19 p.m. EDT after 6 hours and 35 minutes.

Prokopyev and Petelin attached three debris shields to the Rassvet module and tested the sturdiness of a work platform affixed to the end of the European robotic arm attached to the Nauka multipurpose laboratory module.

This was the eighth spacewalk in Prokopyev’s career, and the sixth for Petelin. It was the tenth spacewalk at the station in 2023 and the 267th spacewalk for space station assembly, maintenance, and upgrades.

Cosmonauts Begin Spacewalk for Station Upgrade Work

Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin began a spacewalk at 10:44 a.m. EDT to attach three debris shields to the Rassvet module outside the International Space Station and to test the sturdiness of a work platform that will be affixed to the end of the European robotic arm attached to the Nauka multipurpose laboratory module.

Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website.

Prokopyev is wearing an Orlan spacesuit with red stripes, while Petelin is wearing the suit with blue stripes. This is the eighth spacewalk in Prokopyev’s career, and the sixth for Petelin. It is the tenth spacewalk at the station in 2023 and the 267th spacewalk for space station assembly, maintenance, and upgrades.

Cosmonauts Exiting Station for Spacewalk Soon Live on NASA TV

NASA coverage is underway for today’s spacewalk with Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin. The duo will exit out of the International Space Station’s Poisk module about 10:45 a.m. EDT to attach three debris shields to the Rassvet module. They also will test the sturdiness of a work platform that will be affixed to the end of the European robotic arm attached to the Nauka multipurpose laboratory module.

Coverage of the spacewalk is on NASA Television, the NASA app, and the agency’s website.

Prokopyev is wearing the Orlan spacesuit with red stripes, while Petelin is wearing the suit with blue stripes.

This will be the eighth spacewalk in Prokopyev’s career, and the sixth for Petelin. It will be the tenth spacewalk at the station in 2023 and the 267th spacewalk for space station assembly, maintenance, and upgrades.

Cancer Therapy, Agriculture Studies One Day Before Spacewalk

Stem cells and space botany were the top research objectives for the Expedition 69 crew on Tuesday while still working to unpack a new U.S. cargo craft. Two cosmonauts are also “go” to exit the International Space Station on Wednesday for more upgrades on the orbital lab.

Life science in microgravity enables researchers to observe biological phenomena and achieve unique insights that would be impossible in Earth’s gravity environment. Scientists then apply the new knowledge potentially improving a variety of Earth-bound conditions including human health and agriculture.

Two experiments aboard the station today addressed new cancer therapies and ways to grow crops in space. NASA Flight Engineer Frank Rubio worked in the Kibo laboratory module servicing stem cell samples for the StemCellEX-H Pathfinder study that seeks to improve therapies for blood diseases and cancers such as leukemia. UAE (United Arab Emirates) astronaut Sultan Alneyadi harvested leaves from thale cress plants that are similar to cabbage and mustard for the Plant Habitat-03 experiment to learn how to grow food and sustain crews on future space missions.

NASA astronauts Stephen Bowen and Woody Hoburg focused their day primarily on orbital maintenance. Bowen replaced air filters in the Destiny laboratory module while Hoburg monitored the performance of the advanced resistive exercise device for troubleshooting in the Tranquility module. The duo also had time set aside for some science activities as Bowen processed his blood samples for analysis and Hoburg tested station potable water samples for quality.

All four astronauts continued unpacking some of the 8,200 pounds of science and supplies delivered aboard the Cygnus space freighter on Friday. Cargo activities will be ongoing until late October when Cygnus departs the station completing a three-month orbital stay.

Two cosmonauts are ready to begin the 10^th spacewalk at the station this year to install orbital debris shields and relocate hardware on the orbital outpost’s Roscosmos segment. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin have completed their procedure reviews and Orlan spacesuit configurations and will begin a six-and-a-half-hour spacewalk at 10:45 a.m. EDT on Wednesday. NASA TV, on the agency’s app and website, begins its live spacewalk coverage at 10:15 a.m.

Flight Engineer Andrey Fedyaev will support the two spacewalkers on Wednesday as he commands the European robotic arm (ERA) from inside the Nauka science module during the planned six-hour and 30-minute excursion. Fedyaev started his day joining Prokopyev and Petelin for the final spacewalk procedures review. He then spent the rest of the day configuring the ERA preparing it for hardware transfers during Wednesday’s spacewalk.
