The Expedition 66 crew split its research schedule between space botany and life science aboard the International Space Station today.
NASA Flight Engineer Thomas Marshburn started Thursday watering plants growing for the Veggie PONDS study that explores ways to reliably grow vegetables in microgravity. Afterward, the three-time space station visitor verified the operability of the two robotics workstations, located in the U.S. Destiny laboratory module and the cupola, that control the Canadarm2 robotic arm.
Matthias Maurer, flight engineer from ESA (European Space Agency), printed samples from a handheld bioprinter for analysis back on Earth. The samples were printed to investigate how to develop tissues in microgravity to advance personalized medicine on Earth and in space.
The three other NASA Flight Engineers aboard the orbiting lab, Raja Chari, and Kayla Barron, Mark Vande Hei, worked throughout the day on a variety of life support and science maintenance tasks. Chari was on plumbing duty draining and transferring fluids in station tanks. Barron serviced the lab’s exercise cycle before replacing components in the waste and hygiene compartment, the station’s bathroom. Vande Hei processed samples for DNA analysis for the Food Physiology experiment that documents how diet affects a crew member’s health during a long-term space mission.
The station’s commander, Anton Shkaplerov of Roscosmos, was back on exercise research on Thursday exploring how to maximize the effectiveness of working out in weightlessness. Russian Flight Engineer Pyotr Dubrov cleaned up the Zvezda and Poisk modules, returning them to a post-spacewalk configuration following his excursion with Shkaplerov on Jan. 19.

Space agriculture dominated the research schedule aboard the International Space Station today to learn how to sustain long-term crews far beyond low-Earth orbit. The Expedition 66 crew also had time set aside for ongoing life science work to help keep astronauts and Earthlings healthy.
NASA Flight Engineers Raja Chari and Kayla Barron spent Wednesday afternoon servicing cotton plant cell samples for the Plant Habitat-5 space botany study. The experiment is investigating how microgravity affects cotton genetic expression possibly impacting plant regeneration on and off the Earth.
NASA Flight Engineer Mark Vande Hei worked on a similar botany study today nourishing Arabidopsis plants grown on petri plates. That study is exploring how plant molecular mechanisms and regulatory networks adapt to the weightless environment of space.
Astronauts Thomas Marshburn of NASA and Matthias Maurer of ESA (European Space Agency) worked throughout the day on research hardware supporting investigations into how space affects biology. Marshburn installed a centrifuge inside the Cell Biology Experiment Facility, an incubator with an artificial gravity generator that cultivates cells and plants inside the Kibo laboratory module. Maurer stowed science gear used for a visual function study after the experiment samples were returned to Earth on Monday inside the SpaceX Cargo Dragon resupply ship.
Commander Anton Shkaplerov from Roscosmos continued his exercise research today studying how to maintain the physical fitness of crew members in weightlessness. Flight Engineer Pyotr Dubrov assisted the commander during the workout study and also swapped fuel bottles inside the Combustion Integrated Rack.
