Mission Diary – 27 January

On this day Tim Peake conducted his Day 46 cognition test. He also assisted Kelly in one of the experiments in the Japanese Experiment Module.

Individualized Real-Time Neurocognitive Assessment Toolkit for Space Flight Fatigue (Cognition) is a battery of tests that measure how spaceflight-related physical changes, such as microgravity and lack of sleep, can affect cognitive performance. Cognition includes ten brief computerized tests that cover a wide range of cognitive functions, and provides immediate feedback on current and past test results. The software allows for real-time measurement of cognitive performance while in space.

Human exploration of space requires astronauts to maintain a high level of effective cognitive performance in the presence of a range of fatigue-related conditions associated with perturbations of sleep and circadian neurobiology, excessive cognitive and physical workloads (e.g., EVAs), and environmental stressors (e.g., CO2, hypoxia , radiation). It is unknown to what extent fatigue is a result of (or interacts with) other occult neurobehavioral risks in space flight (e.g., reports of cognitive space fog; symptom reports of neurasthenia (nervous exhaustion); visual field deficits from papilledema (edema of the optic disk) and/or the possibility of elevated intracranial pressure (ICP) in space).

Given the breadth of neurocognitive functions required for effective performance in space, the need to medically manage sleep and fatigue in space, the very limited neurocognitive assessment tools currently in space flight, and the often anecdotal nature of cognitive complaints from space flight, there is a critical need for rapid objective assessment of a range of neurocognitive performance functions in space flight.

This project achieves this goal by developing a much-needed practical, yet comprehensive cognitive test battery; validating its sensitivity to fatigue and fatigue countermeasures; determining astronaut norms for the test battery; and establishing space-flight feasibility of the battery. The result is a software-based Neurocognitive Assessment Toolkit for Spaceflight (Cognition) that permits rapid, real-time measurement of astronaut cognitive performance across a much broader range of neurocognitive functions than can be currently assessed in space.

The Cognition battery is a 20-30 minute computerized test battery of cognitive tests. Besides a sleep questionnaire and brief subjective evaluations at the beginning, Cognition contains the following 10 tests (each test is mentioned with the primary cognitive domains covered):

  1. Motor Praxis (MPraxis): Sensory-motor ability
  2. Visual Object Learning (VOLT): Visual object learning and memory
  3. Fractal 2-Back (F2B): Attention and working memory
  4. Abstract Matching Task (AMT): Abstraction
  5. Line Orientation (LOT): Spatial orientation
  6. Emotion Recognition (ER): Emotion recognition
  7. Matrix Reasoning (MRsT): Abstract reasoning
  8. Digit Symbol Substitution (DSST): Complex scanning, visual tracking, attention
  9. Balloon Analog Risk (BART): Risk decision making
  10. Psychomotor Vigilance (PVT): Vigilant attention and psychomotor speed.

While living and working in orbit, astronauts must be able to perform complex tasks despite fatigue and stress. Cognition provides a way to test crew members’ cognitive performance by using a battery of tests. The experiment validates the sensitivity of the battery to fatigue and its effectiveness for use in space. Future missions could use Cognition software to measure crew members’ performance more effectively than current tests.

A minimum of 6 ISS crew members are needed as subjects for this experiment. Cognition software is loaded on the subject’s laptop for pre/post-flight testing and on the Human Research Facility Laptops for in-flight testing. The Cognition battery should be performed in the evening within 2 hours of going to bed and with as little distraction as possible. Consumption of caffeine and medications potentially influencing performance will be recorded by the software prior to the start of each test battery. Pre- and post-flight data is uploaded to the PI’s secure website after test completion. In-flight data will be downlinked within a week of each test session.

Cognition is completed 11 times in-flight. For a six month mission, the first 4 tests are completed weekly and the remaining tests are completed once every few weeks. For a one year mission, the first test is completed on FD 6 and subsequent tests are performed at 34 day intervals All testing occurs on the Human Research Facility Laptops and data is downlinked within a week of each session.

ISS Daily Report 26 January

Burning and Suppression of Solids – Milliken (BASS-M):  Yesterday Kopra completed reconfiguration of the Microgravity Science Glovebox (MSG) Facility and started setup of hardware for BASS-M. Today he completed the BASS-M setup. During the setup, there was an issue with the data from the power/video unit. He was able perform troubleshooting and recover the data, however due to the extended time the first BASS-M run had to be deferred. The BASS-M investigation tests flame-retardant cotton fabrics to determine how well they resist burning in microgravity. Results benefit research on flame-retardant textiles that can be used on Earth and in space.

Low Earth Orbiting Navigation Experiment for Spacecraft Testing Autonomous Rendezvous and Docking (LONESTAR):  Today Kelly and Peake opened the Japanese Experiment Module (JEM) Airlock inner hatch and extended the Airlock Slide Table into the JEM. They then installed the Cyclops deployer on the Slide Table, installed a Small Fine Arm (SFA) Plate on Cyclops, and then installed the Lonestar on Cyclops.  Lonestar contains satellites AggieSat4 (built by Texas A&M University students) and Bevo-2 (built by University of Texas students).  Deployment is planned for Friday, January 29. After free-flying safely away from the ISS, AggieSat4 will eject the BEVO-2 satellite. Both satellites then perform cross-linking communications, exchange data, link to GPS, and transmit to ground radio stations. LONESTAR is used to further develop and refines autonomous navigation, rendezvous and docking software and procedures.  Future NASA missions to destinations such as asteroids and other celestial bodies require the use of autonomous navigation systems.

Cognition:  Peake performed his Flight Day 46 session of the Cognition experiment today. The Individualized Real-Time Neurocognitive Assessment Toolkit for Space Flight Fatigue (Cognition) investigation is a battery of tests that measure how spaceflight-related physical changes, such as microgravity and lack of sleep, can affect cognitive performance. Cognition includes ten brief computerized tests that cover a wide range of cognitive functions, and provides immediate feedback on current and past test results. The software used allows for real-time measurement of cognitive performance while in space.

Dynamic Surf 3: Peake exchanged the Video Recording Unit (VRU) hard disk drive within JAXA’s Image Processing Unit (IPU) for the Dynamic Surf 3 investigation.  A disk drive filled with data generated from the experiment was replaced with a fresh drive for continued recording. The Dynamic Surf 3 investigation is part of a series of JAXA experiments designed to provide insight into the underlying principles of Marangoni convection. These experiments demonstrate in microgravity the flow transition phenomena from steady to oscillatory, chaotic, and finally turbulent. Observations are made of fluid convection during formation of a silicone oil liquid bridge that is generated by differential heating of two discs within the Fluid Physics Experiment Facility (FPEF). The results of this investigation could ultimately drive the design and development of more efficient fluid flow based systems and devices.

Ras Labs-CASIS-ISS Project for Synthetic Muscle: Resistance to Radiation (Synthetic Muscle):  Peake took a set of historical photos of the synthetic muscle samples.  The purpose of this investigation is to measure the effects of radiation on proprietary synthetic muscle materials in space and earth environments. Robots made of these materials could provide assistance to humans in space, enhance survivability of robots during deep space travel, and provide support in extreme radiation environments on Earth.

Fine Water Mist Portable Fire Extinguishers (PFE) Deployment:  Kopra deployed two Fine Water Mist PFEs today. Once the Fine Water Mist PFEs were stowed in the USOS Portable Emergency Provision (PEP) locations, Kopra attached new instruction cue cards to the exterior of each location. Fine Water Mist PFEs are the preferred type of fire extinguisher for open cabin fire scenarios, but cannot be used behind racks. In the event that a Fine Water Mist PFE is unavailable, a CO2 PFE may still be used.

Orbital ATK (OA)-4 Cargo Operations:  All three USOS Crew will continue transferring Cygnus cargo to ISS today. As of yesterday afternoon, approximately 22 hours remain to be completed. Cygnus is scheduled to unberth from ISS on 19 February.

ISS Reboost:  ISS performed a reboost this afternoon using the Progress 61P thrusters. This reboost is the second in a series of reboosts to target the planned conditions for the Soyuz 44 landing on 2 March, Soyuz 46 four orbit rendezvous on 19 March, and Progress 63 four orbit rendezvous on 31 March.

Payload Multiplexer/Demultiplexer (MDM) #2 Loss Of Communications:  Overnight Payload MDM #2 experienced a High Rate Data Link (HRDL) card latch up, which prevented communications with the MDM and ISS Payloads. Flight Controllers attempted to command a reset of the card twice without success. They then commanded a MDM transition to Payload MDM #1 and have restored communications to ISS Payloads. Later, Ground teams power-cycled Payload MDM #2 in order to recover communications with the unit. The MDM is currently serving as a backup to Payload MDM #1
