Aboard the International Space Station, the Expedition 55 crew continued exploring how plants adapt to gravity and began preparing for a suite of combustion experiments. The trio is also continuing the maintenance of the station’s life support systems and its microgravity science operations.
NASA astronaut Scott Tingle put his green thumb to work today supporting a pair of botany experiments. He set up gear for an upcoming run of the Plant Gravity Perception experiment that will monitor how plants perceive light and gravity. Tingle also watered and harvested red lettuce for consumption today for the ongoing Veggie-03 study.
After lunch, Tingle opened up the Combustion Integrated Rack and installed new gear to get ready for the Advanced Combustion Microgravity Experiment (ACME). ACME is a set of five independent studies researching gaseous flames in space that may enable more fuel efficient and less polluting technologies.
Flight Engineer Norishige Kanai of the Japan Aerospace Exploration Agency worked on networking gear in the Kibo lab module before inspecting smoke detectors in the Columbus lab module. Kanai then collected data on new adjustable lights installed inside Kibo before conducting plumbing work in the station’s Waste and Hygiene Compartment. Finally, he and Tingle wrapped up the work day with an Earth photography session of Baja California and China.
Commander Anton Shkaplerov continued his work on Russian life support systems through the day. He ended his work day with a photographic inspection of a pair Russian docking modules.
