New Expedition#73 Crew Photos: Part 1 | International Space Station

NASA astronauts (left to right) Anne McClain and Nichole Ayers, both Expedition 73 Flight Engineers, pose for a portrait together aboard the International Space Station's Harmony module. Moments earlier, Ayers finished trimming McClain's hair using an electric razor with a suction hose attached that collects the loose hair to protect the station's atmosphere.

Astronauts Takuya Onishi of Japan Aerospace Exploration Agency (JAXA) and Nichole Ayers of NASA, Expedition 73 Commander and Flight Engineer respectively, are pictured inside the International Space Station's Harmony module. Ayers trims Onishi's hair using an electric razor with a suction hose attached that collects loose hairs to protect the station's atmosphere.

Astronauts Jonny Kim of NASA and Takuya Onishi of the Japan Aerospace Exploration Agency (JAXA), Expedition 73 flight engineer and commander respectively, work inside the International Space Station's Harmony module gathering and organizing cargo to be packed inside the SpaceX Dragon cargo spacecraft before its departure.

NASA astronaut and Expedition 73 Flight Engineer Anne McClain works inside the Destiny laboratory module's Materials Science Research Rack and swaps filters inside the Kermit microscope. Kermit is an all-in-one fluorescence microscope system used to conduct biological, physical, and materials science research.

NASA astronaut and Expedition 73 Flight Engineer Nichole Ayers conducts research operations inside the Kibo laboratory module's Life Science Glovebox aboard the International Space Station. Ayers was processing samples of deep-sea bacteria to test a specialized 3D microscope for its ability to monitor water quality, detect potentially infectious organisms, and study liquid mixtures and microorganisms in space and on Earth.

NASA astronaut and Expedition 73 Flight Engineer Nichole Ayers replaces components on an experimental carbon dioxide removal device. Also called the Thermal Amine Scrubber, the advanced life support mechanism is testing a new method that removes carbon dioxide from the station’s atmosphere and recovers water for oxygen generation.
