The Expedition 68 crew members conducted space health experiments and prepared for the final plant harvest aboard the International Space Station while inspiring the next generation of explorers in a virtual robotics competition.
NASA Flight Engineer Woody Hoburg spent most of his day installing tissue cassettes for the BFF-Meniscus-2, an investigation to print and culture a meniscus using the BioFabrication facility aboard the space station. Crew members who experience musculoskeletal injuries on future deep space missions may benefit from the capability to bioprint tissue to promote recovery. The research could lead to the ability to print complex tissues and organs that may be used to treat patients on Earth.
NASA Flight Engineer Frank Rubio conducted the Astrobee-Zero Robotics operations, a programming competition where students earn the opportunity to control an autonomous flying robot and observe its performance aboard the space station. Finalists have their code downloaded by NASA to the Astrobee platform and observe its performance. Rubio also continued to transfer the 6,200 pounds of research hardware and supplies between the orbital outpost and the uncrewed SpaceX CRS-27, which arrived at the space station on March 16.
Afterward, Rubio spent the rest of his day preparing for the final harvest of the Veg-05 plants by collecting plant swabs and water samples to be stored in cold stowage for later use in research. The plant botany study is the next step in addressing the need for a food production system in space. The Vegetable Production System supplies crew members with a continuous source of fresh food and a tool for relaxation and recreation.
NASA Flight Engineer Stephen Bowen installed Materials International Space Station Experiment-17-Commercial hardware onto the Japanese Experiment Module airlock slide table. The investigation tests how the space environment affects the durability of materials and components, including 3D-printed polymers, thermal protection systems, spacecraft materials, biopellets made from dried microbes, paraffin wax thermal protection, and thin solar cells.
Flight Engineer Sultan Alneyadi from UAE (United Arab Emirates) removed the Dry-EEG Headband and synchronized the unit to the European Physiology Module laptop for data transfer. The sleep monitoring technology investigates astronauts’ sleep quality by measuring duration, sleep stages, heart rate, and the number of awakenings. Alneyadi then positioned the Astrobee free flyer in the Japanese Experiment Module and conducted software test runs.
Flight Engineer Andrey Fedyaev of Roscosmos continued to replace the condensate evacuation lines that carry away excess moisture from the cabin atmosphere. Meanwhile, Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin prepared cargo to return in the Soyuz MS-22 spacecraft, slated to undock from the station’s Rassvet module on March 28.

The Expedition 68 crew members conducted experiments and maintained equipment aboard the International Space Station while activities for cargo transfers continued.
NASA Flight Engineer Frank Rubio performed microscopy and video recordings on eight BioCell tissue chambers for the Cardinal Heart 2.0 in the Life Sciences Glovebox. This investigation uses heart organoids to test whether clinically approved drugs reduce microgravity-induced changes in heart cell function. Rubio also removed the Advanced Resistive Exercise Device’s (ARED) cylinder flywheel and inspected the treadmill as part of monthly maintenance. The ARED exercises all major muscle groups while focusing on the primary resistive exercise: squats, deadlifts, and heel raises. Crew members exercise daily on ARED to maintain preflight muscle and bone strength during long periods in space.
Flight Engineer Sultan Alneyadi from UAE (United Arab Emirates) recorded a video of Cardinal Heart 2.0 tissue chambers. The investigation tests clinically approved pharmaceutical drugs to reverse the negative effects on heart cells and tissues caused by prolonged exposure to the space environment. Afterward, Alneyadi removed the Bio-Monitor garment and headband and synchronized the unit to the controller for data transfer. Alneyadi donned the Dry-EEG Headband overnight for sleep studies in space. Considering the central role of sleep in human behavior and health, sleep quality is a key factor for current and future exploration missions. The investigation monitors crew members’ quality of sleep by measuring duration, sleep stages, heart rate, and the number of awakenings.
Additionally, Rubio and Alneyadi spent the evening continuing to transfer the 6,200 pounds of research hardware and supplies between the space station and the uncrewed SpaceX CRS-27, which arrived at the orbital outpost on March 16.
Flight Engineer Andrey Fedyaev of Roscosmos continued to replace the condensate evacuation lines that carry away excess moisture from the cabin atmosphere.
