Sleep ISS-12 [The ISS-12 experiment monitors the ambient light exposure and crew member activity and collects data on the subjective evaluation of sleep and alertness. Ambient light and activity are monitored via a wrist-worn actiwatch that delivers actiwatch spectrums that are put through bio-mathematical models of sleep and light to predict circadian phase. Sleep logs will be kept by crew members as a subjective assessment of sleep quality and duration. It is hoped that this investigation can deliver requirements for lighting, sleep-shifting protocols and workloads for future space exploration missions.]

Ocular Health – Tonometry & Blood Pressure Measurements [OH is a human physiology study. Its full name is Prospective Observational Study of Ocular Health in ISS Crews. “The Prospective Observational Study of Ocular Health in ISS Crews (Ocular Health) protocol aims to systematically gather physiological data to characterize the Risk of Microgravity-Induced Visual Impairment/Intracranial Pressure on crewmembers assigned to a 6 month ISS increment,” the NASA experiment overview said. It is known that some (not all) astronauts in orbit experience changes in visual acuity (visual clarity) and intraocular pressure as a result of fluid shifts within the body as it is subjected to microgravity. About 20% is astronauts flying to ISS have reported these kinds of changes. Test subjects will undergo pre-flight, flight and post-flight testing of their eyes using a variety of techniques.]

PZEh-MO-8 Body Mass Measurement (All Crew Members) [Measuring body mass in Zero-G, where matter is weightless, but not massless, is accomplished by measuring the inertial forces that arise during the oscillatory motion of a mass driven by two helical metering springs with known spring constants. By logging the period of each oscillation of the crew member and comparing it to the period of a known mass, the unknown mass can be calculated.]

X2R14 Software Transition: ISS Multiplexers/Demultiplexers & Portable Computer Systems continue to be put through the transition to the latest software package.

Node 3 Carbon Dioxide Removal Assembly: CDRA experienced a Heater Controller B fault requiring the Lab CDRA to be activated. The Node 3 CDRA was configured for operation on a single heater string and re-started as planned, now in standby mode.
