On Thursday, the Expedition 72 crew began activating new experiments after a full day unpacking the SpaceX Dragon cargo spacecraft. They deployed new scientific equipment and stored new research samples on the International Space Station (ISS).
Senior flight engineer Don Pettit focused on DNA research, starting with collecting water samples on the station to test for microbes. He then extracted DNA from these microbial samples for analysis and identification. Meanwhile, flight engineer Nick Hague placed biological equipment in the Life Sciences glove compartment of the Kibo laboratory module to investigate how space conditions might cause inflammation in organisms. Later in his shift, Pettit used medical imaging equipment to examine Haig’s eyes, testing the hypothesis that B-Complex vitamin supplementation could help prevent vision problems caused by long-term space travel.
NASA flight engineer Butch Wilmore worked in the Destiny laboratory module and installed new physics equipment in the Microgravity Science Glovebox, which measures the motions of particles in liquids. The research uses microgravity to learn how to separate viruses from biological fluids to detect diseases. Commander Suni Williams activated mixing tubes containing proteins and bacteria for student-designed NanoRacks Module-9 experiments, improving the health of crew members and encouraging future space explorers. Williams also worked on various scientific maintenance tasks while continuing to unpack the Dragon spacecraft.
The Canadarm2 robotic arm is on the Harmony module to retrieve experimental solar wind measurement equipment from the trunk of the SpaceX Dragon cargo spacecraft. Robotic engineers on site will remotely control Canadarm2 and its finely tuned Dextre robotic arm to carefully remove the solar meter from the Dragon on Saturday. Then on Monday, the solar experiment will be installed on the left side of the orbital outpost’s integrated lattice structure and will soon begin operating there. The CODEX, or Coronal Diagnostic Experiment, will use the coronagraph to filter bright sunlight to reveal the outer atmosphere, or corona, and investigate how the solar wind forms.
