ISS Daily Summary Report – 2/01/2019

Circadian Rhythms: Today a crewmember doffed the Circadian Rhythms hardware. This completes the 3rd session for this increment. Circadian Rhythms investigates the role of synchronized circadian rhythms, or the “biological clock,” and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour cycle of light and dark affects crewmembers’ circadian clocks.

The ISS Experience: Today a crewmember setup the ISS Experience hardware in the US Lab in order to record portions of the CIR ACME reconfiguration and chamber insertion into the CIR rack. ISS Experience creates a virtual reality film documenting daily life aboard the space station. The 8 to 10 minute videos created from footage taken during the six-month investigation cover different aspects of crew life, execution of science aboard the station, and the international partnerships involved. The ISS Experience uses a Z-CAM V1 Pro Cinematic VR (Virtual Reality) 360-degree camera with nine 190° fisheye lenses. 

Advanced Combustion via Microgravity Experiments (ACME): Today a crew completed the part 2 of the ACME hardware reconfiguration. The ACME experiment series being performed in the CIR includes five independent studies of gaseous flames. The primary goals of ACME are to improve fuel efficiency and reduce pollutant production in routine fuel combustion activities on Earth. Its secondary goal is to improve spacecraft fire prevention through innovative research focused on materials flammability.

Universal Waste Management System (UWMS): The crew successfully installed a new double stall enclosure within Node 3 today. During the activity, the crew experienced a water leak while de-mating a Quick Disconnect (QD) for the potable water bus. Approximately 9.5 liters leaked before the bus was isolated by MCC-H flight controllers. The crew worked quickly to re-mate the leaky QD and soak up the water with towels. An alternate QD was then de-mated in order to continue with the installation. The new concept, referred to as the Universal Waste Management System (UWMS), includes favorable features from previous designs while improving on other areas from Space Shuttle and the existing ISS Waste Collection System (WCS) hardware. This double stall enclosure provides privacy for both the Toilet System and the Hygiene Compartment. The starboard side will provide access to the existing toilet and the port side will be used for hygiene until new replacement Toilet System arrives in early 2020.
