The International Space Station (ISS) has been a cornerstone of human space exploration since its inception, serving as a microgravity and space environment research laboratory. On January 27, 2016, the ISS was in the midst of Expedition 46, a mission that provided valuable insights into long-duration spaceflight and its effects on the human body. This article delves into the status of the ISS on that date, highlighting crew activities, scientific experiments, and operational updates.

Expedition 46 Overview

Expedition 46 commenced in March 2015 and was scheduled to conclude in March 2016. The crew comprised six members: NASA astronaut Scott Kelly, Russian cosmonauts Mikhail Kornienko and Sergey Volkov, British astronaut Tim Peake, and American astronauts Tim Kopra and Kimiya Yui. Notably, Kelly and Kornienko were undertaking a one-year mission to study the physiological and psychological effects of extended space travel on the human body. This mission aimed to gather data crucial for future deep-space exploration, including potential missions to Mars. ([nasa.gov](

Crew Activities on January 27, 2016

On January 27, 2016, the ISS crew engaged in a series of activities that underscored the station's multifaceted operations:

  • Preparation for Nanosatellite Deployment: The crew prepared for the deployment of two nanosatellites from the Japanese Kibo laboratory. These student-designed satellites were part of an educational initiative aimed at fostering interest in space science and technology among students. ([nasa.gov](
  • Cygnus Cargo Operations: The crew loaded trash into the Cygnus cargo spacecraft, which was scheduled to depart the station. This routine activity ensured the efficient management of waste and the maintenance of a clean environment aboard the ISS. ([nasa.gov](
  • Spacewalk Preparations: The crew reviewed timelines and procedures for an upcoming spacewalk planned for February 3, 2016. This spacewalk aimed to continue the installation of International Docking System Standard (IDSS) components, enhancing the station's capability to accommodate future spacecraft. ([nasa.gov](
  • Orbital Reboost Maneuver: The ISS conducted an orbital reboost to adjust its altitude in preparation for the upcoming crew swap and cargo delivery activities scheduled for March. This maneuver ensured the station's orbit remained optimal for docking operations. ([](

Scientific Research and Experiments

Beyond daily operations, the ISS continued to serve as a hub for scientific research on January 27, 2016:

  • Human Physiology Studies: Astronauts Scott Kelly and Tim Kopra participated in eye and blood pressure checks as part of the Ocular Health study. This research aimed to understand how long-duration spaceflight affects vision and cardiovascular health, providing insights into the challenges of extended missions. ([nasa.gov](
  • Touch-Based Technology Research: British astronaut Tim Peake conducted experiments to study how living in space affects the use of touch-based technologies. This research was crucial for developing user interfaces suitable for space environments, ensuring astronauts can effectively interact with onboard systems. ([](

Environmental Control and Life Support Systems (ECLSS) Status

Maintaining the ISS's life support systems is critical for crew safety and mission success. As of January 27, 2016, the status of key ECLSS components was as follows:

  • Elektron: Operational
  • Vozdukh: Manual mode
  • SM Air Conditioner System (SKV1): Operational
  • SM Air Conditioner System (SKV2): Offline
  • Carbon Dioxide Removal Assembly (CDRA) Lab: Operating
  • Carbon Dioxide Removal Assembly (CDRA) Node 3: Override mode
  • Major Constituent Analyzer (MCA) Lab: Idle
  • Major Constituent Analyzer (MCA) Node 3: Operating
  • Oxygen Generation Assembly (OGA): Processing
  • Urine Processing Assembly (UPA): Standby mode
  • Trace Contaminant Control System (TCCS) Lab: Full Up mode
  • Trace Contaminant Control System (TCCS) Node 3: Offline

These systems are integral to maintaining a habitable environment aboard the ISS, ensuring the crew's health and safety during their mission. ([](

Upcoming Events and Preparations

Looking ahead, several key events were scheduled for the ISS in the days following January 27, 2016:

  • Cygnus Cargo Transfer: The Cygnus spacecraft was set to depart the ISS, carrying waste and unneeded items, thereby maintaining the station's cleanliness and operational efficiency. ([](
  • PS120 J Installation: Installation of the PS120 J component was planned, contributing to the station's ongoing upgrades and maintenance. ([](
  • JPM Internal Port Camera Relocation: A camera relocation within the Japanese Pressurized Module (JPM) was scheduled to enhance visual monitoring capabilities. ([](
  • Lonestar Deployment: The deployment of the Lonestar experiment was planned, aiming to advance scientific research in space. ([](
  • Spacewalk (EVA) 3: A spacewalk was scheduled for February 3, 2016, to continue the installation of IDSS components, enhancing the station's docking capabilities. ([en.wikipedia.org](

These activities reflect the ISS's continuous efforts to advance scientific knowledge, maintain operational readiness, and prepare for future missions.
