NASA Space Station On-Orbit Status 28 October 2020 – Space Physics Research
The Canadarm2 robotic arm and the Cygnus resupply ship.

The Expedition 64 crew continued this week’s run of space physics and human research aboard the International Space Station today.
The orbital trio also spent the day servicing laptop computers and life support systems.

During Wednesday morning, Flight Engineer Kate Rubins of NASA installed material samples inside the Handhold Experiment Platform (HXP) that will soon be exposed to the harsh environment of space. She then placed the Japanese external experiment platform inside the Kibo laboratory module’s airlock. From there the Japanese robotic arm will grapple the HXP with the samples inside and install it outside Kibo. Scientists observe the materials over time to understand how space radiation and extreme temperatures affect a variety of samples, impacting the design of future spacecraft and advanced materials.

Rubins then moved onto fluid physics during the afternoon, setting up hardware for the Drop Vibration experiment. Engineers may be able to take advantage of the results to design advanced fuel, water, and air systems on spacecraft.

Flight Engineer Sergey Kud-Sverchkov of Roscosmos began wrapping up operations for a Russian immune system study. After collecting his saliva samples, he stowed the experiment’s hardware and transferred science data for later analysis. He also participated in a space exercise study to maintain a crew member’s health during long-term missions.

During the morning, Commander Sergey Ryzhikov took part in the same exercise study as his fellow cosmonaut. The veteran cosmonaut then explored ways to improve interactions among international crews and mission control teams. Ryzhikov also upgraded software on a variety of laptop computers and checked airflow sensors throughout orbiting lab’s Russian segment.

On-Orbit Status Report


Drop Vibration Gather and Review: The crew reviewed the procedures and gathered the appropriate hardware to support the installation on Thursday. Inertial Spreading with Vibration and Water Coalescence (Drop Vibration) examines the behavior of big liquid drops whose perimeter of contact, called the contact line, moves rapidly as the drops change shape either forced by vibration or freely by merger. These motions, fast and small on Earth, become slower and larger in microgravity and so can be more closely observed. Such observations improve the currently limited understanding of contact lines, important in applications such as self-cleaning surfaces, water harvesting devices, anti-frost coatings and the fabrication of semiconductors.

Exposed Experiment Handrail Attachment Mechanism (ExHAM) Sample Attach: In support of ExHAM #2, the crew installed Handhold Exp (HXP) Platform s/n 002 on the HXP adapter and stowed HXP s/n 001. Following this, the crew installed the ExHAM#2 experiments/samples. Taking advantage of Kibo’s unique function of having both an airlock and a robotic arm on the ISS, the ExHAM facility enables space experiments to be performed in the exposed space environment, by attachment to the Japanese Experiment Module Kibo’s Exposed Facility.


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.
