NASA Space Station On-Orbit Status 2 October 2019 - Change of Command.

Two Expedition 60 crewmates and a visiting astronaut are returning to Earth on Thursday. The orbiting Expedition 61 residents staying on the International Space Station will then turn their attention to a series of spacewalks set to begin this weekend.

Commander Alexey Ovchinin handed over control of the orbiting complex today to astronaut Luca Parmitano of ESA (European Space Agency) during the change of command ceremony. The Expedition 61 mission will officially begin when the three Expedition 60 crewmates depart the station.

NASA astronaut Nick Hague is returning to Earth with Ovchinin and visiting astronaut Hazzaa Ali Almansoori of the United Arab Emirates. The trio will board the Soyuz MS-12 crew ship and undock from the station's Rassvet module on Thursday at 3:36 a.m. EDT. They will parachute to landing in Kazakhstan at 7 a.m. (5 p.m. Kazakh time).

There was still time for research today as NASA Flight Engineer Andrew Morgan took turns with Parmitano exploring cognition and motion in space. Morgan also installed the Small Optical Communication System, or SOLISS, that is testing the real-time downlink of large amounts of data from the station.

The first of five spacewalks to upgrade power systems on the orbital complex starts Sunday at 7:50 a.m. NASA astronaut Christina Koch will join Morgan and exit the station's Quest airlock in their U.S. spacesuits to begin installing new lithium-ion batteries on the Port-6 truss structure. The duo will work outside in the vacuum of space for about six hours and 30 minutes.

On-Orbit Status Report

Change of Command Ceremony and 58S Undock/Landing: Today, the ISS Crew participated in a Change of Command Ceremony during which Expedition 60 Commander Aleksey Ovchinin handed over command of the ISS to Expedition 61 Commander Luca Parmitano. Aleksey Ovchinin, Nick Hague, and Hazzaa Al Mansoori will return to Earth tomorrow morning on 58S with undocking scheduled for 2:36 AM CT and landing in Kazakhstan planned at 6:00 AM CT.

Acoustic Diagnostics: The crew set up the appropriate hardware and performed an ESA Acoustic Diagnostic experiment session. The investigation tests the hearing of ISS crew members before, during, and after flight. This study assesses the possible adverse effects of noise and the microgravity environment aboard the ISS on human hearing. The investigation compares the relationship between the detection of otoacoustic emissions, sounds naturally generated from within the inner ear, and hearing loss levels when exposed to noisy environments.

Food Physiology: The crew performed saliva collections in support of the food physiology experiment. The Integrated Impact of Diet on Human Immune Response, the Gut Microbiota, and Nutritional Status During Adaptation to Spaceflight (Food Physiology) experiment is designed to characterize the key effects of an enhanced spaceflight diet on immune function, the gut microbiome, and nutritional status indicators. These factors are interlinked, but diet is the only one that can be easily and meaningfully altered on Earth or during flight. This investigation aims to document the effect of dietary improvements on human physiology and the ability of those improvements to enhance adaptation to spaceflight.

GRIP: The crew performed the supine science 3 sessions. In these sessions, also known as the References Supine sessions, the crew performs the same set of trials as in References Seated, but in the supine position. The GRIP experiment consists of 3 protocols: Dynamics Seated, References Seated and References Supine. ESA's Grip investigation tests how the nervous system takes into account the forces due to gravity and inertia when manipulating objects. Results from this investigation may provide insight into potential hazards for astronauts as they manipulate objects in different gravitational environments. They also support design and control of haptic interfaces to be used in challenging environments such as space, and provide information about motor control that will be useful for the evaluation and rehabilitation of impaired upper limb control in patients with neurological diseases.

Rodent Research (RR) acoustic test: The crew installed an acoustic monitor in a RR habitat to better characterize the noise environment in the habitats in various locations. This is being done to address noises reported in the EXPRESS1 and EXPRESS2 rack areas. The Rodent Research suite of investigations study the effects of microgravity on mice.

SOLISS: The SOLISS (Demonstration of Small Optical Communication System) hardware was installed on the JEM airlock slide table in preparation for later installation onto an Exposed Facility location. SOLISS is planned to demonstrate use of an optical communication system to provide more than 100Mbps downlink speed from the International Space Station (ISS). This optical communication system employs a 1550nm laser emitted from an Erbium Doped Fiber Amplifier (EDFA) with a 500mW maximum laser output. SOLISS power, communication and cooling are provided from the EFU (Exposed Facility Unit) Adapter on the Japanese Experiment Module (JEM) exposed facility platform interface.

Time Perception: Using a head-mounted Oculus Rift display/headphones, a finger trackball, and support computer, the crew performed the Time Perception experiment sessions. In this experiment, 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.

USOS P6 Battery Extravehicular Activity (EVA) Preparations: Last night, ground operators completed robotic get-ahead operations to support the P6 Battery EVAs.The Special Purpose Dexterous Manipulator (SPDM) was used to release the H1 bolts and break torque on the H2 bolts for all 6 Li-Ion Batteries on Exposed Pallet (EP) 8. The first P6 Battery EVA is planned for this Sunday, October 6.
