The Expedition 61 crew members contributed to hundreds of experiments in biology, Earth science, human research, physical sciences and technology development, including improvements to the Alpha Magnetic Spectrometer in an effort to extend its life and support its mission of looking for evidence of dark matter and testing 3D biological printers to print organ-like tissues in microgravity.
Koch shared her most memorable moments, from her arrival to the space station on March 14, 2019, to her first glimpse of her hometown on Earth from space, to her first spacewalk.
