 NASA Astronaut Christina Hammock Koch will be making her second flight to space on the Artemis II mission, serving as a mission specialist. Koch served as flight engineer aboard the space station for Expedition 59, 60, and 61. Koch set a record for the longest single spaceflight by a woman with a total of 328 days in space and participated in the first all-female spacewalks. Photographer: Robert Markowitz

Rep. Robert Aderholt, R-Ala., is seen as he watches the beginning of the first all-woman spacewalk on Friday, Oct. 18, 2019, from the Space Operations Center at NASA Headquarters in Washington. The first all-woman spacewalk in history began at 7:38am EDT with NASA astronauts Christina Koch and Jessica Meir venturing outside the International Space Station to replace a failed battery charge-discharge unit. This is the fourth spacewalk for Koch and Meir’s first. Photo Credit: (NASA/Joel Kowsky)

Front Row: Commander Reid Wiseman, Howard Hu, Mission Specialist Christina Koch, Mission Specialist Jeremy Hansen, General David Stringer, Back Row: Carlos Garcia Galan, Howard Hu, John Zang, Josh Pawlak, Nicole Smith, Jan-Henrik Horstmann, Robert Overy, Kathryn Oriti pose in front of the Orion Environmental Test Article at Armstrong Test Facility in Sandusky, OH. The team has begun vibro-acoustic testing on the Orion spacecraft that flew around the Moon on Artemis I, now known as the Environmental Test Article. The testing will help ensure the safety of future crews aboard Orion. Employees meet three of the four astronauts who will venture around the Moon on Artemis II, the first crewed flight paving the way for future lunar surface missions. Commander Reid Wiseman and Mission Specialists Christina Koch and Jeremy Hansen will be on hand to discuss their upcoming mission and participate in a Question and Answer session with employees afterward. Hansen is an astronaut with the Canadian Space Agency. Victor Glover, the pilot and fourth crew member, will not be present. Awards were given to employees that participated in Orion for Artemis I.

jsc2023e010175 (2/28/2023) --- This image shows a monospecies biofilm through the view of a scanning electron microscope. The image was colored to visualize the bacterial cells (orange) embedded in the biofilm matrix (blue). The biofilm was formed by a strain of the bacterial species Staphylococcus capitis that was isolated from the International Space Station. The ESA-Biofilms investigation studies bacterial biofilm formation and antimicrobial properties of different metal surfaces under spaceflight conditions in altered gravity. The image was taken as part of the preflight experiments for ESA-Biofilms together with the Robert Koch Institute in Berlin, Germany. Image courtesy of DLR, CC BY-NC-ND 3.0.
