ISS Daily Summary Report – 9/14/2020


Burning Rate Emulator (BRE): The crew reconfigured the ACME hardware in preparation for BRE experiment runs. This includes swapping in Igniter Arm #2. The Burning Rate Emulator (BRE) investigation is conducted in the Combustion Integrated Rack (CIR) on the International Space Station (ISS), as part of the Advanced Combustion via Microgravity Experiments (ACME) project. In this fire safety study, the flammability of solid and liquid materials is simulated by burning gaseous fuels under key conditions corresponding to the solid and liquid materials. This technique has been demonstrated for a wide variety of materials in normal-gravity and could provide an efficient way to screen and select fire-resistant materials for use in spacecraft, if the technique is similarly effective in microgravity.

Light Microscopy Module (LMM): The crew removed the ACE-T4 module and configured the LMM for Confocal Target test operations. The Light Microscopy Module (LMM) is a modified commercial, highly flexible, state-of-the-art light imaging microscope facility that provides researchers with powerful diagnostic hardware and software onboard the International Space Station (ISS). The LMM enables novel research of microscopic phenomena in microgravity, with the capability of remotely acquiring and downloading digital images and videos across many levels of magnification. The way that matter is organized and moves on the microscopic level profoundly affects the macroscopic world and an understanding of such processes helps scientists and engineers build more efficient materials and machines both for both the earth and space environments.


Robotics External Leak Locator (RELL) Checkouts: Today, robotic ground controllers (ROBO) activated the Mobile Servicing System (MSS) Special Purpose Dexterous Manipulator (SPDM) and are currently in the process of performing checkouts of the two RELL units that are stowed in the Robotic Tool Stowage (RiTS). RELL survey operations are planned for the Radiator Beam Valve Modules (RBVM) of the S1 truss Heat Rejection System (HRS). The RELLs are mass spectrometer “sniffers” that will be used to assist in the investigation of possible External Active Thermal Control System (EATCS) anhydrous ammonia (NH3) leaks. The EATCS coolant loops cool external electrical systems as well as transport heat away from internal water cooling systems that are required keep critical ISS avionics from overheating.

Environmental Health System (EHS) Total Organic Carbon Analyzer (TOCA) Water Recovery System (WRS) Sample Analysis & Data Record: Crew performed an analysis of the water processing assembly (WPA) using the TOCA. The TOCA unit oxidizes organic carbon species present in the water to carbon dioxide gas and measures the concentration using nondispersive infrared spectroscopy. Analysis of the potable water using the TOCA occurs on a weekly basis. The crew replaced the TOCA Waste-Water Bag (WWB) just prior to the sample collection to preclude overfill.
