NASA Space Station On-Orbit Status 18 January 2018 - Preparing for U.S. Spacewalk 47

A pair of spacewalks are planned for Jan. 23 and 29 to swap and stow external robotics gear. NASA astronaut Mark Vande Hei will lead both spacewalks.

Flight Engineer Scott Tingle will join him on the first spacewalk with Japanese astronaut Norishige Kanai joining Vande Hei on the second.

Vande Hei, Tingle and Kanai checked the spacesuits today they will wear outside the International Space Station for the two robotics maintenance spacewalks. Flight Engineer Joe Acaba assisted the spacewalkers with their spacesuit fit checks and helped collect spacewalk tools.

Vande Hei and Tingle will exit the U.S. Quest airlock Tuesday at 7:10 a.m. EST for six-and-a-half hours of work on the Canadarm2 robotic arm. NASA TV will cover the spacewalk live beginning at 5:30 a.m. The duo will swap a Latching End Effector (LEE) with a spare one. The LEE is the part of the Canadarm2 that grapples and releases spaceships and station hardware.

On-Orbit Status Report

Plant Habitat Gaseous Nitrogen (GN2) Hose Connection: Today the crew removed and replaced the acoustic blanket and growth chamber door before retrieving the GN2 filter and connecting it to the EXpedite the PRocessing of Experiments to Space Station (EXPRESS) Rack nitrogen. The other end was connected to the GN2 hose in order to perform a GN2 leak check. Plant Habitat is a fully automated facility that will be used to conduct plant bioscience research on the International Space Station (ISS). It occupies the lower half of the EXPRESS Rack and two International Subrack Interface Standard (ISIS) drawers, providing a large, enclosed, environmentally controlled chamber.

Circadian Rhythms: Today a 53S crewmember instrumented themselves with Thermolab Double Sensors, mounted the Thermolab Unit to their belt, and began 36 hours of monitoring for the Circadian Rhythm investigation. Circadian Rhythms investigates the role of synchronized circadian rhythms, or the "biological clock," and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour cycle of light and dark affects crewmembers' circadian clocks. The investigation also addresses the effects of reduced physical activity, microgravity and an artificially controlled environment. Changes in body composition and body temperature, which also occur in microgravity, can affect crewmembers' circadian rhythms as well. Understanding how these phenomena affect the biological clock will improve performance and health for future crewmembers.

Wireless Sensor Network (WiseNet) Hardware Installation: Today the crew installed the WiseNet Base Station on MagVector rack front panel, inserted the USB Boot Stick, and installed WiseNet sensors at dedicated locations inside the US Lab, Node 2, and Columbus. The goal of the WiseNet technology demonstrator is to establish the functionality of low power Radio Frequency (RF) networks within the ISS environment using low power sensor-nodes. These sensors form a wireless network on board ISS to monitor environmental factors such as temperature, pressure, and humidity.

Earth Imagery from ISS Target (EIISS): The crew took images of Southern California using the Red camera. EIISS is used to support creation of a series of videos highlighting Earth views taken from space. The videos are taken with cameras on the ISS in 6K hi-resolution and are integrated into videos for screensavers for public enjoyment.

Transition to (X2) R16 Software: In order to complete the R16 software transition, ground controllers configured the Environmental Control and Life Support System (ECLSS) and Thermal Control System (TCS) equipment and then updated the software on the S0, LSYS, and LA-2 Multiplexor-Demultiplexors (MDMs). After the MDM updates were completed, the ground controllers returned the ECLSS and TCS equipment to the nominal configuration.

Extravehicular Activity (EVA) Operations: The crew performed on orbit fit verification (OFV) operations to configure Extravehicular Mobility Units (EMUs) 3003 and 3008 properly for the upcoming EVAs. The crew also configured EVA tools for use outside the station. Next Tuesday, two crewmembers will exit the station and perform maintenance on the Space Station Remote Manipulator System (SSRMS) by swapping a Latching End Effector (LEE) from the SSRMS with a spare.
