Crew Works Ongoing Spacecraft Operations, Robotics, and Combustion Science

Docked spacecraft operations were the main focus at the International Space Station on Thursday with crew departure training, cargo packing, and an orbital reboost also taking place. The Expedition 72 crew also worked on science hardware activating a free-flying robotic assistant and preparing for a fire safety experiment.

NASA’s SpaceX Crew-9 members which includes NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, as well as Roscosmos cosmonaut Aleksandr Gorbunov joined each other on Wednesday for a refresher session and practiced on a computer the procedures for reentering the Earth’s atmosphere aboard the SpaceX Dragon crew spacecraft. The quartet is planned to undock from the space station about a week after NASA’s SpaceX Crew-10 mission arrives carrying NASA astronauts Anne McClain, Nichole Ayers, Roscosmos cosmonaut Kirill Peskov, and JAXA (Japan Aerospace Exploration Agency) Takuya Onishi. Crew-10’s four crew members are targeted to launch no earlier than March 12 from the Kennedy Space Center in Florida.

Hague and Gorbunov also trained to use a new tool that measures airflow velocity from vents aboard the station. Williams replaced ammonia leak emergency response procedures with new safety manuals delivered on Aug. 6, 2024 aboard the Cygnus space freighter. Wilmore swapped fuel bottles inside the Combustion Integrated Rack to prepare for a spacecraft fire safety study that explores how flames spread in microgravity.

NASA Flight Engineer Don Pettit was back on robotics duty on Wednesday powering up an Astrobee robotic free-flyer for the Astrobee-Zero Robotics student competition to program the toaster-sized device to make a variety of maneuvers. Winning students had their algorithms uploaded to Astrobee testing its ability to autonomously detect and move objects within a time limit aboard the Kibo laboratory module.

The space station is orbiting higher after the Progress 89 cargo craft, which is docked to the rear port of Zvezda service module, fired its thrusters for over 22 minutes on Wednesday night. The reboost places the station at the correct altitude to receive the new Progress 91 craft after it launches on Feb. 27 then docks on March 1.

Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner packed the Progress 89 with trash and discarded hardware in preparation for cargo craft’s undocking on Feb. 25. Ovchinin also prepared the Progress 89 for its departure removing air ducts and checking its hatch. Vagner moved on and serviced Zvezda’s oxygen generator while Gorbunov photographed the condition of stowage areas in the Zarya module. Following the Progress 89’s departure, Zvezda’s rear port will be vacated where the Progress 91 will dock beginning a six-month cargo mission.

Spacesuits, Exercise Gear, and Spacecraft Operations Fill Wednesday Schedule

On Wednesday, the Expedition 72 crew aboard the International Space Station focused its efforts mostly on spacesuits and advanced exercise gear. The orbital residents also worked on crew and cargo spacecraft operations at the orbital outpost.

NASA Flight Engineers Butch Wilmore and Nick Hague joined each other in the Quest airlock and swapped components on a spacesuit in preparation for a spacewalk planned in the spring. Next, Wilmore wrapped up the suit work and stowed the spacewalking hardware in Quest. Hague relocated medical operations gear from Quest into the Tranquility module and checked their wireless configurations.

Station Commander Suni Williams worked inside the Columbus laboratory module on futuristic exercise gear designed by the European Space Agency. She powered up the Portable Pulmonary Function System (PPFS) and tested its network connectivity with other space station exercise systems. The PPFS measures a variety of respiratory and cardiovascular factors such as oxygen intake, heart rate, blood pressure, and more helping researchers learn more about space biology and determine the effectiveness of space exercise techniques.

NASA’s SpaceX Crew-9 astronauts also joined Roscosmos cosmonaut Aleksandr Gorbunov and reviewed procedures on computer tablets for unlikely spacecraft emergency scenarios such as a fire or depressurization. The quartet is targeted to return to Earth aboard the SpaceX Dragon crew spacecraft in March several days after the SpaceX Crew-10 mission launches which is currently targeted for no earlier than March 12.

NASA Flight Engineer Don Pettit kicked off his day in the Kibo laboratory module inspecting and swapping out wireless communications gear. Next, he documented his daily food and medicine intake before he installed a pair of temporary hatch window covers in the Unity and Harmony modules.

Gorbunov worked on water transfers between the U.S. and Roscosmos segments of the orbital lab then cleaned ventilation systems inside the Poisk module. His fellow cosmonauts, Flight Engineers Alexey Ovchinin and Ivan Vagner, continued packing trash and discarded gear inside the Progress 89 cargo craft due to leave the station on Feb. 25. Ovchinin, along with Gorbunov, then took a test documenting his experience communicating with mission controllers from around the world. Vagner pointed a camera with a spectrometer installed toward Earth and photographed landmarks in a variety of wavelengths.

Crew Works Robotics Competition and 3D Bioprinter to Manufacture Cells, Tissues

The Expedition 72 crew spent Tuesday setting up a free-flying robotics competition for students and a cleaning a 3D bioprinter. The International Space Station residents also conducted blood and saliva tests, cleaned crew quarters, and packed a cargo ship for departure.

Flight Engineer Don Pettit powered up an Astrobee robotic free flyer at the beginning of his shift on Tuesday and cleared space in the Kibo laboratory module to allow the toaster-sized device to maneuver on its own. Ground controllers then took over and tested Astrobee’s autonomous flight trajectories and its ability to recognize hand gestures. The operations are being set up in advance of the Astrobee-Zero Robotics competition that will see students write algorithms controlling Astrobee to clear objects inside Kibo in a set amount of time.

The BioFabrication Facility (BFF), located in the Columbus laboratory module, is being tested for its capability to print biological, or organ-like, tissues in space and eventually fabricate human organs off the Earth. NASA Flight Engineer Nick Hague spent his shift cleaning pumps, replacing components, and installing bio-ink syringes inside the BFF ensuring ongoing research operations. Print files are uploaded from the ground to the 3D bioprinter, then cells are printed inside a cassette, and finally the cassettes are stowed in a sample processor for 60 days before being returned to Earth for later analysis.

Hague also joined station Commander Suni Williams collecting their blood and saliva samples for testing. The duo processed the blood draws in a centrifuge then stowed the samples in a science freezer for later analysis. Researchers on Earth will examine the specimens to understand how living in weightlessness affects an astronaut’s health. Williams then spent the rest of her day charging batteries on an eye imaging tool, draining orbital plumbing systems, and analyzing station water samples for contaminants.

A Roscosmos Progress 89 cargo craft is due to depart the orbital lab on Feb. 25 after six months docked to the rear port of the Zvezda service module. Cosmonauts Alexey Ovchinin and Ivan Vagner packed the Progress 89 with trash and discarded gear and transferred fluids inside the resupply ship before it completes its mission. The Progress 91 cargo craft will replace the Progress 89 when it launches on Feb. 27 and docks to Zvezda’s vacated port two days later.

Cosmonaut and Flight Engineer Aleksandr Gorbunov began his shift powering down an Earth observation camera before inspecting and servicing electronic and ventilation systems inside the orbital outpost’s Roscosmos segment. Gorbunov had a light duty shift during his afternoon then wrapped up his day with a standard medical conference.

Muscle Research, Blood Tests To Promote Healthy Crews End Week

Muscle stimulation and blood tests topped the International Space Station research schedule on Friday helping doctors learn how to keep astronauts healthy on long-term missions. The Expedition 72 residents also winded down the work week cleaning spacesuits and life support gear aboard the orbital outpost.

Astronauts use their legs less often aboard the station and need to exercise daily to offset the muscle loss. NASA Flight Engineers Nick Hague and Don Pettit partnered together inside the Columbus laboratory module and explored using electrical stimulation to maintain their leg muscles in addition to the crew’s two-hour daily exercise sessions. Hague was attached to a control unit and electrodes as electrical signals excited his muscles, potentially improving muscle function and endurance in space, while Pettit monitored the research operations. The lack of gravity impacts the human body in many ways and scientists are studying the physiological changes astronauts experience to learn how to counteract those changes. Results may lead to more efficient space exercise methods and smaller, lighter workout equipment on space missions.

The two astronauts started their day collecting their blood samples for processing and stowage in a science freezer. The samples will later be analyzed to understand the physiological changes astronauts experience while living and working on long-term space missions. Hague would later review procedures to install space botany hardware while Pettit prepared the Mochii electron microscope for future imaging operations.

Station Commander Suni Williams spent her day in the Quest airlock servicing a spacesuit following a Jan. 30 spacewalk she conducted with Flight Engineer Butch Wilmore. She emptied and filled suit water tanks, cleaned cooling water loops, and installed lithium-ion batteries ensuring the suit’s readiness for future spacewalks.

Wilmore worked inside the Destiny laboratory module on Friday inspecting, cleaning, and installing new components on an experimental carbon dioxide removal system. The Four Bed Carbon Dioxide Scrubber seeks to demonstrate improved reliability and performance for next-generation life support systems on future spacecraft. Researchers examine carbon dioxide samples from the device and monitor the station’s atmosphere and monitor its operation as crews of various sizes come and go.

Roscosmos Flight Engineers Aleksandr Gorbunov and Alexey Ovchinin took a regularly computer-based hearing test in the quiet area of their crew quarters. Gorbunov also worked throughout Friday on orbital plumbing duties in the Nauka science module. Alexey Ovchinin also replaced electronics and communications hardware before filling an oxygen generator with water. Flight Engineer and cosmonaut Vagner cleaned pumps and pipes inside the Zvezda service module and photographed materials that had been exposed to the external environment for a Roscosmos space experiment.

Vein Scans, Muscle Study on Station Informing Ways to Keep Crews Healthy

Human research, the series of ongoing investigations to understand how to keep astronauts healthy while living long-term in space, was the main science topic aboard the International Space Station on Thursday. The Expedition 72 residents also continued packing a cargo craft for its upcoming departure and conducted an emergency drill to stay familiar with response, communication, and coordination procedures.

Four NASA astronauts took turns Thursday morning in the Columbus laboratory module using the Ultrasound 2 device to scan their neck, shoulder, and leg veins. Flight Engineers Butch Wilmore and Nick Hague kicked off the biomedical work as Wilmore powered up the Human Research Facility and its ultrasound hardware. Next, Wilmore scanned Hague’s veins as doctors on the ground monitored in real-time guidance.

Hague then took control of the Ultrasound 2 and scanned the veins of station Commander Suni Williams while she relaxed in the Columbus lab. Afterward, Hague handed over the ultrasound device to Flight Engineer Don Pettit taking his turn as crew medical officer to scan the veins of Wilmore with remote guidance from specialists on Earth. Doctors will use the downlinked medical data to gain insights into crew health and learn how the human body adjusts to living and working in weightlessness.

After the vein scans, Pettit began setting up hardware and connecting electrical gear for the new Muscle Stimulation experiment that seeks to counter space-caused muscle atrophy in crew members’ legs with improved exercise methods. Hague collected his urine samples and stowed them in a science freezer for future testing. Wilmore finalized packing radio communications hardware that had been removed from outside the orbital outpost during a Jan. 30 spacewalk.

Williams also activated an Astrobee robotic free flyer that maneuvered inside the Kibo laboratory module demonstrating its ability to capture and stream live video back to Earth. Williams then retrieved samples of engineered yeast from an incubator and stowed them in a science freezer for later analysis to determine their ability to produce on-demand nutrients on future missions.

Roscosmos cosmonaut Aleksandr Gorbunov pointed a camera out a Zvezda service module window and photographed Earth landmarks in a variety of wavelengths. Flight Engineer Alexey Ovchinin collected trash and obsolete gear for disposal aboard the Progress 89 cargo craft before its departure at the end of February. Flight Engineer Ivan Vagner worked on ventilation maintenance in the Nauka science module.

At the end of their shift, all seven Expedition 72 crewmates gathered together and practiced a regularly scheduled emergency drill. The orbital septet worked in conjunction with mission controllers around the world and followed simulated emergency drill steps on computer tablets. The crew then reviewed procedures to follow in the unlikely event of a depressurization, chemical leak, or fire aboard the space station.
