NASA Space Station On-Orbit Status 23 October 2020 – Station Maintenance

It is back to work for three Expedition 64 crewmates today following a day of rest on Thursday.
The trio is ramping up space research while continuing the upkeep of the International Space Station.

NASA astronaut Kate Rubins began her day replacing batteries in devices that detect smoke and compounds in the station’s atmosphere. She then serviced a variety of research hardware including Spectrum which images proteins in fluorescent light. Rubins then worked on a device that applies a known force to a crew member and uses the resulting acceleration to calculate an astronaut’s mass in microgravity.

Station Commander Sergey Ryzhikov had a light duty day Friday. The two-time resident of the orbiting lab spent some time dusting and cleaning crew quarters before replacing components in the Russian toilet.

First-time space flyer Sergey Kud-Sverchkov inspected Russian hardware today including a food warmer and an onboard control system. The cosmonaut Flight Engineer also configured a pair of laptop computers with assistance from mission specialists on the ground.

On-Orbit Status Report

Payloads

SPECTRUM Plate Remove: The crew powered off the SPECTRUM facility, opened the SPECTRUM facility access door and removed and trashed the SPECTRUM-001 plant growth plates. The goal of the session was to check out the SPECTRUM facility capabilities with a plant growth plate inserted. Although some network difficulties were experienced, the SPECTRUM team was able to successfully check out the facility. Spectrum takes fluorescent images of biological specimens contained within a controlled environment. A high resolution, monochrome camera captures images of fluoresced proteins of plants within Petri plates. Ground crews control the growth lighting, CO2 levels, and ethylene levels within the Spectrum’s research chamber over a typical 12-day growth period while routinely capturing images and telemetering these images back to Earth.

Turbine-Ceramic Manufacturing (T-CMM) Module: The crew installed the T-CMM and related cables into its EXPRESS rack location and took photos of the installed hardware. Turbine CMM demonstrates manufacture of single-piece turbine blade/disk combinations (blisks) in microgravity for commercial use. Manufacturing blisks in space could produce parts with lower mass, lower residual stress, and higher strength than those made on Earth due to greatly reduced sedimentation of the solution in microgravity.

Systems

Compound Specific Analyzer-Combustion Products (CSA-CP) Extended Maintenance: The crew replaced battery packs in all six deployed CSA-CPs and zero calibrate all units. The CSA-CPs provide real-time readings following a combustion event and subsequent clean-up efforts. The CSA-CP is also used for continuous monitoring of carbon monoxide levels in the ISS

Space Linear Acceleration Mass Measurement Device (SLAMMD): The crew set up the SLAMMD equipment and then conducted mass measurement runs for five cargo bags of varying mass and size. The use of SLAMMD is intended to provide an accurate means of determining the on-orbit mass of humans or cargo items.
