NASA Space Station On-Orbit Status 21 May 2019 - Preparing for the Next Russian Spacewalk.

The Expedition 59 crew is spending all day Tuesday exploring how astronauts adjust with Earth's gravity no longer bearing down on them. Spacewalk preparations and lab maintenance are also ongoing aboard the International Space Station.

Station crewmembers and future astronauts going to the Moon in 2024 have to adjust to the lack of a sunrise/sunset cycle humans experience everyday on Earth. As a result, time perception is impacted and may affect sleep and work patterns. Astronauts Anne McClain, Nick Hague and David Saint-Jacques started the day on a study, going on since July 2017, exploring subjective changes in time that can alter physical and cognitive performance.

Hague later sequenced DNA samples for a study exploring how increased exposure to space radiation impacts crew health. He used the Biomolecule Sequencer for the investigation to demonstrate DNA sequencing in space. The Genes In Space-6 experiment is researching how space radiation damages DNA and how the cell repair mechanism works in microgravity.

Immune system studies continued full speed ahead today to test the hypothesis the immune response decreases in space. Astronaut Christina Koch teamed up with McClain and Saint-Jacques throughout the day observing mice for the study. Observations may help scientists develop advanced vaccines and therapies benefiting both astronauts and Earthlings.

Commander Oleg Kononenko continues to set up a pair of Russian Orlan spacesuits and outfit the Pirs airlock as the May 29 spacewalk approaches. Flight Engineer Alexey Ovchinin worked on space cardiology research before switching to space plumbing and pumping urine into the Progress 71 cargo craft.

On-Orbit Status Report

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.
