Time Perception in Microgravity: The crew performed Time Perception sessions. A program on the laptop induces visual and audio stimuli to measure a subject’s response to spatial and time perception in a microgravity environment. The accurate perception of objects in the environment is a prerequisite for spatial orientation and reliable performance of motor tasks. Time is fundamental to motion perception, sound localization, speech, and fine motor coordination.

Rodent Research-12 (RR-12): The crew performed research ops today. Rodent Research-12, Tetanus Antibody Response by B cells in Space (TARBIS), examines the effects of spaceflight on the function of antibody production and immune memory. Spaceflight is known to have a dramatic influence on immune response, but there is little research on its effect following an actual challenge to the body’s immune system. Using a mouse model makes this possible, as the mouse immune system closely parallels that of humans.

Genes in Space-6: The crew performed Genes in Space-6 operations by loading samples from Experiment kit 1 into the Biomolecule Sequencer and the analysis run was initiated. Deoxyribonucleic Acid (DNA) damage caused by increased exposure to radiation can affect the long-term health of astronauts. Genes in Space-6 determines the optimal DNA repair mechanisms that cells use in the spaceflight environment. The investigation evaluates the entire process in space for the first time by inducing DNA damage in cells and assessing mutation and repair at the molecular level using the miniPCR and the Biomolecule Sequencer tools aboard the space station.
