NASA Space Station On-Orbit Status 9 July, 2020 - Studying Water Conservation

The International Space Station was orbiting almost directly above Marfa, Texas, on a southeastern orbital trek that would take it over Mexico and across South America.

The International Space Station was a hive of activity today with the Expedition 63 crew practicing emergency skills, examining eyes and studying water conservation.

Two astronauts also will continue more battery swaps in a pair of spacewalks set to begin next week.

Living 260 miles above the Earth and orbiting the planet 16 times a day presents a unique set of risks that space residents must be prepared for. Today, NASA Commander Chris Cassidy joined Roscosmos Flight Engineers Anatoly Ivanishin and Ivan Vagner for a simulated emergency evacuation of the station. The trio spent the afternoon practicing quickly entering their Soyuz MS-16 crew ship for a rapid undocking and Earth re-entry.

Afterward, Cassidy partnered up with his fellow NASA astronauts Doug Hurley and Bob Behnken for eye exams at the end of the day. Hurley led the effort as the Crew Medical Officer and used optical coherence tomography gear to scan the retinas of his two crewmates.

Behnken and Cassidy are set to go out on two more spacewalks scheduled for July 16 and 21. The duo will continue replacing aging nickel-hydrogen batteries with new lithium-ion batteries on the starboard portion of the station's truss structure. The batteries store and release power collected from the orbiting lab's main solar arrays.

Robotics controllers overnight commanded the Canadarm2 robotic arm to replace a failed remote power control module (RPCM) on the port truss segment. The replacement restores redundancy to the solar alpha rotary joint after the old RPCM failed last week.

In the Russian side of the station, Vagner primarily worked on housekeeping chores as he checked water tanks and cleaned air filters. Ivanishin spent some time photographing the effects of Earth catastrophes and exploring how international crews and ground controllers communicate with each other.

On-Orbit Status Report

Droplet Formation Study (DFS) installation: The crew installed the DFS investigation hardware into the Microgravity Science Glovebox (MSG). The investigation is scheduled to begin later this month. Droplet Formation Studies in Microgravity (Droplet Formation Study, or more simply DFS) evaluates water droplet formation and water flow of Delta Faucet's H2O kinetic shower head technology. To conserve water, flow rates in shower devices have been reduced, but this lower flow rate also reduces the effectiveness of these devices and often causes consumers to take longer showers, undermining the goal of using less water. Gravity's full effects on formation of water droplet size are unknown, and research in microgravity could help improve the technology, creating better performance and improved user experience while conserving water and energy.

Fluids Integrated Rack/Light Microscopy Module/Advanced Colloids Experiment (FIR/LMM/ACE) module photos: The crew gathered and took images of several ACE-T10 and ACE-T12 modules. This will allow the experiment team to determine the viability of the samples and plan future operations accordingly. ACE-T10 studies crystal nucleation in colloidal fluids, the origin of ageing in glasses and gels, as well as the heterogeneous nature of the microscopic dynamics in these structures. ACE-T12 involves design and assembly of complex three-dimensional (3D) structures from colloids, or particles of different sizes suspended in a fluid. It employs a recently discovered technique, Nanoparticle Haloing (NPH), which uses highly charged nanoparticles to stabilize much larger, non-charged particles.

Materials Science Research Rack/Materials Science Laboratory (MSRR/MSL) review: The crew reviewed the materials and gathered the hardware needed for tomorrow's furnace exchange from the LGF (Low Gradient Furnace) to the SQF (Solidification and Quench Furnace). This furnace exchange is needed to support the next planned MSL experiments. The MSL is used for basic materials research in the microgravity environment of the ISS. The MSL can accommodate and support diverse experiment modules. Many material types, such as metals, alloys, polymers, semiconductors, ceramics, crystals, and glasses, can be studied to discover new applications for existing materials and new or improved materials.

Urine Transfer System (UTS) installation: The crew continued with the installation of the UTS. The UTS is part of a new toilet system that will serve as both a technology demonstration, and a capability to support additional crew members on the ISS. The UTS is used to collect pre-treated urine and connects to the ISS Urine Processor Assembly (UPA) for recycling. The UTS allows operation of both the existing Russian Toilet (ACY) located in the Waste and Hygiene Compartment (WHC) rack and the new Toilet. The UTS consists of valves and controllers which open and close depending on the priority flow path from either the Toilet or WHC. Each toilet can deliver pretreated urine to the UPA or a Russian urine tank (EDV-Y).

Systems

ExtraVehicular Activity (EVA) H-Fixture Review: The EV crew was unable to remove the H-fixture during US EVA #66. Ground teams uplinked three videos showing options for removing the H-Fixture from the mounting bracket and requested the crew's feedback. The crew reviewed the videos today and provided feedback for the ground teams to consider for the upcoming Channel 3B EVA 1.

H-II Transfer Vehicle (HTV)9 Cargo Operations: Today, the crew continued to perform HTV9 cargo transfer operations. Ground teams estimate approximately 2 hours remain to complete available cargo ops. Total cargo ops time remaining will become better defined as additional disposal chits are processed.

On Board Training (OBT) Soyuz Emergency Drill: Today the 62S crew performed an Emergency Egress Drill. During this drill, the 62S crew reviewed procedures needed during off-nominal situations before using the onboard trainer to practice the actions required in the event of an emergency egress and Soyuz descent. The crew also completed self-study reviews of various nominal procedures to include Sokol suit donning and leak checks. This training is scheduled every 12-14 weeks and ensures the crew is adequately prepared to respond to an on-orbit emergency.

Health Maintenance System (HMS) Eye Exams: Today the crew performed a routine eye exam using Optical Coherence Tomography (OCT). OCT is an imaging technique analogous to ultrasound imaging that uses light instead of sound to capture micrometer-resolution, two and three-dimensional images of tissue. Eye exams are performed regularly onboard in order to monitor crewmember's eye health. Eyesight is one of the many aspects of the human body affected by long-duration stays in a microgravity environment.

United States On-orbit Segment (USOS) Hatch Seal Inspection: The crew performed this regularly scheduled preventive maintenance to clean and inspect USOS hatch seals, hatch plate sealing surface and hatch handle mechanisms for foreign object debris or damage. The crew inspected the Airlock IV, PMM, JPM Zenith, JLP, and Node 3 (Fwd, Stbd, Nadir) hatches.

Mobile Servicing System (MSS) Ops: RPCM P32B_A was robotically replaced and powered up successfully. The robotic arm stowed the failed RPCM in the Cargo Transportation Container-5 (CTC-5) located on the Express Logistics Carrier-3 (ELC-3). MDM P3-2 is now powered on and in its nominal state and the Port SARJ was returned to autotrack. The Mobile Transporter (MT) was successfully translated from Work Site (WS) 7 to WS5 in support of the SPDM stow prior to setup for Channel 3B EVA 1.
