Crew Explores Cellular Immunity, Digestion and Waits for Cargo Mission

Cellular immunity and digestion were the main research topics on Wednesday as the Expedition 72 crew explored space biology aboard the International Space Station. The orbital residents also worked on spacesuit maintenance and prepared for the arrival of a new cargo mission this weekend.

NASA Flight Engineer Nick Hague began his day collecting his blood and saliva samples for the Immunity Assay investigation. Before breakfast, he began his saliva work processing and stowing the samples in a science freezer. Then he treated his blood samples and spun them in a centrifuge before finally loading the specimens in a pair of temperature controlled Kubik incubators. The samples will be analyzed on the space station to understand space-caused cellular stress and tissue damage. Results may reveal how an astronaut’s immune system responds to the lack of gravity and improve ways to monitor crew health on missions farther away from Earth.

Spacesuit work filled the day for NASA Flight Engineers Don Pettit and Butch Wilmore who partnered together inside the Quest airlock. The duo cleaned water cooling loops, swapped components, and checked the communications system on a spacesuit following a pair of spacewalks in January and before another spacewalk planned for the spring. Pettit later loaded disposable cargo inside the Cygnus space freighter while Wilmore removed space physics hardware from inside the Microgravity Science Glovebox.

NASA’s station Commander Suni Williams spent her day on inspection activities throughout the orbital outpost’s U.S. segment. She looked at portable fire extinguishers, breathing masks, emergency air supply tanks, and other safety hardware ensuring their functionality. Williams completed her shift inside the Columbus laboratory module inspecting air ducts inside temporary crew quarters that host visiting crews for short periods of time.

Roscosmos Flight Engineers Aleksandr Gorbunov and Ivan Vagner joined each other for ultrasound scans of their stomachs before and after breakfast on Wednesday to understand how weightlessness impacts their digestion system. Gorbunov then collected air samples in the Zvezda, Nauka, and Rassvet modules for analysis. Vagner later joined Flight Engineer Alexey Ovchinin and trained for an upcoming cargo mission.

The Roscosmos Progress 91 cargo craft is at its launch pad at the Baikonur Cosmodrome in Kazakhstan counting down to launch at 4:42 p.m. EST on Thursday. The Progress 91 is scheduled to dock to Zvezda’s aft port at 6:03 p.m. on Saturday delivering three tons of food, fuel, and supplies to the Expedition 72 crew. Vagner and Ovchinin prepared for the Progress 91’s arrival and trained on the TORU, or telerobotically operated rendezvous unit, located in Zvezda that can remotely command and control an approaching Roscosmos spacecraft if necessary.

Free Flying Robotics, Space Agriculture Ahead of Cargo Mission Swap

Free flying robotics and space agriculture topped Tuesday’s research schedule as the Expedition 72 crew helps advance the space industry. The International Space Station will also see the departure of a cargo craft and the arrival of its replacement this week.

NASA’s station Commander Suni Williams began her day setting up and activating the Astrobee robotic assistant, a cube-shaped, toaster-sized technology demonstration device, inside the Kibo laboratory module. Next, she outfitted the Astrobee with tentacle-like grippers for a test of its ability to autonomously detect and capture simulated orbital debris. Afterward, ground controllers took control of Astrobee and programmed the robotic free flyer to perform maneuvers to locate a capture target then reach out and grapple the free-floating object. Researchers are testing the ability of robots to safely remove orbital debris and protect satellites.

Following the robotics demonstration, NASA Flight Engineer Don Pettit worked in Kibo installing research components on the Advanced Plant Habitat hosting growing Red Romaine lettuce. The space botany hardware divided the young plants into quadrants for observation and provided a temperature sensor device measuring leaf temperature between watering periods. Insights from the Plant Habitat-07 investigation may inform ways to grow crops on future space missions.

NASA astronauts Nick Hague and Butch Wilmore spent their day primarily focusing on science hardware, life support maintenance, and cargo transfers. Hague started his shift in the Columbus laboratory module partially uninstalling the Navigation and Communication Testbed that could provide a more accurate alternative to satellite systems for lunar navigation. Hague then powered up a pair of incubators for biology research later in the week. Wilmore began his day draining recycling tanks then loaded trash inside the Cygnus space freighter ahead of its departure next month. Wilmore wrapped up his shift installing software on a science laptop computer in the Destiny laboratory module.

Roscosmos’ Progress 89 cargo craft is poised to depart the space station at 3:17 p.m. EST today when it undocks from the Zvezda service module’s aft port completing a six-month cargo mission. It will be replaced by the Progress 91 cargo craft after it launches at 4:24 p.m. on Thursday from the Baikonur Cosmodrome in Kazakhstan. The Progress 91, carrying three tons of food, fuel, and supplies, will dock to Zvezda’s vacant port at 6:03 p.m. on Saturday where it will stay for another six months.

Cosmonauts Alexey Ovchinin and Ivan Vagner prepared on Tuesday for the Progress 91’s arrival setting up the TORU, or tele-robotically operated rendezvous unit, inside Zvezda. The TORU can be used to command and control an approaching spacecraft from Roscosmos if necessary.

Vagner then moved on and scanned cosmonaut Aleksandr Gorbunov’s eyes with the Ultrasound 2 device for a regularly schedule exam. Gorbunov also completed a 24-hour session that measured his cardiac activity and blood pressure with portable electrodes.

Crew Off-Duty Monday Before Week of Research, Cargo Spacecraft Missions

The seven-member Expedition 72 crew relaxed on Monday before beginning a week with a host of advanced space research into robotics, biology, and more at the International Space Station. The orbital residents will also send off a cargo craft after a six-month mission before another resupply ship arrives to replace it this weekend.

The orbital outpost’s four NASA astronauts and three Roscosmos cosmonauts began the workweek with an off-duty day following a weekend of light science duties and housecleaning tasks. The crewmates will go into the rest of the week exploring a variety of science of topics running the gamut of advanced space technology, space agriculture techniques, and how astronauts adapt to long-term weightlessness.

Some of the experiments will include NASA’s station Commander Suni Williams setting up an Astrobee robotic free flyer for a demonstration of its ability to autonomously detect and capture space debris with tentacle-like grippers. NASA Flight Engineer Don Pettit will install space botany hardware for an investigation growing Red Romaine lettuce to learn how to grow crops on future space missions. NASA Flight Engineer Nick Hague will focus his scientific attention on human research this week as he collects his blood and saliva samples for analysis and explores electrical muscle stimulation to supplement space exercise.

NASA Flight Engineer Butch Wilmore is due to spend his week on spacesuits and cargo packing. Wilmore will join Pettit cleaning cooling loops and replacing components on a pair of spacesuits inside the Quest airlock. He will also complete a space physics experiment before packing trash and discarded gear inside Northrop Grumman’s Cygnus space freighter.

Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner are gearing up for the undocking of the Progress 89 cargo craft from the Zvezda service module planned for 3:17 p.m. EST on Tuesday. The duo finalized packing the Progress 89 for its departure and Ovchinin will be photographing the resupply ship as it backs away from the orbital outpost.

The Progress 91 spacecraft will launch from the Baikonur Cosmodrome in Kazakhstan at 4:24 p.m. on Thursday before docking to Zvezda’s vacated port 6:03 p.m. on Saturday. Ovchinin and Vagner will be on duty Saturday monitoring the Progress 91’s automated approach and docking.

Roscosmos Flight Engineer Aleksandr Gorbunov spent an hour-and-a-half on Monday attaching electrodes to himself for a 24-hour session monitoring his cardiac activity and blood pressure.

Muscle, Eye, and Breath Research Keeping Crews Healthy in Weightlessness

The muscle, eye, and respiratory research that took place Friday on the International Space Station is helping doctors keep crews healthy on long term space missions and informing possible treatments on Earth. The Expedition 72 crew members also explored space agriculture while working on spacesuits and emergency training.

NASA Flight Engineer Nick Hague attached electrodes to his legs that stimulated his muscles for an investigation exploring ways to counteract space-caused muscles loss. He worked in the Columbus laboratory module where a control unit sent electrical signals exciting his leg muscles. Results may improve muscle function, shorten workout sessions, and lead to lighter exercise equipment in space.

Afterward, Hague joined NASA Flight Engineer Don Pettit for eye exams using standard medical imaging gear in the Harmony module. Pettit assisted Hague as he peered into the optical device while doctors on the ground observed Hague’s eyes in real time. Spaceflight can cause swelling where the optic nerve attaches to the back of the eye. Researchers are exploring a B vitamin supplement as a way to offset that condition, called Spaceflight-Associated Neuro-ocular Syndrome, or SANS, and protect astronauts as NASA and its international partners plan missions to the Moon, Mars, and beyond.

Earlier, Pettit removed samples from inside the Electrostatic Levitation Furnace (ELF) and stowed them inside a bag for return to Earth. The ELF, located inside the Kibo laboratory module, safely heats materials with a high melting temperature to study thermophysical properties unobtainable in Earth’s gravity. The benefits of microgravity research inside the high temperature physics device may lead to the creation of new materials leading to new industrial applications.

NASA astronaut and current space station Commander Suni Williams spent her day inside the Quest airlock servicing spacesuit and spacewalking tool batteries. NASA Flight Engineer Butch Wilmore also joined her activating communication and oxygen systems and swapping life support gear on two spacesuits. Earlier in his shift, Wilmore thinned the leaves of Red Romaine lettuce plants growing inside Kibo’s Advanced Plant Habitat. The lettuce is growing to study how to grow crops on future space missions.

Roscosmos Flight Engineers Alexey Ovchinin and Ivan Vagner partnered together and wore sensors measuring their exhalation rate for an experiment to understand how microgravity affects the respiratory system. Flight Engineer Aleksandr Gorbunov worked on life support systems throughout Friday then wrapped up his shift installing imaging hardware to observe Earth’s nighttime atmosphere in ultraviolet wavelengths.

At the end of the day, all seven Expedition 72 crew members gathered together and trained to use the Anomaly Gas Analyzer (AGA) emergency hardware. The AGA can measure and detect gases in the station’s environment that may require the crew wear protective masks. The orbital septet also reviewed ammonia leak emergency procedures then conducted a safety conference with ground teams.
